WEATHER OF THE WEEK ENDING JUNE 29
HIGHLIGHTS: The hottest temperatures in many years occurred over the Southwest.
The coolest weather in several weeks spread over the Northeast. Numerous severe
thunderstorms spotted south from Texas to South Carolina.
PRECIPITATION: Wide areas from California to the central Great Plains received
no rain or only light sprinkles during the week. Numerous light to moderate
scattered thundershowers occurred in the Northwest but most weekly totals did not
exceed 0.50 inch. Much heavier showers in the Northeast and across the South from
Texas to the Atlantic Ocean. Generous showers fell in the Northeast on Friday and
Saturday with flash flooding resulting in parts of Pennsylvania. Heavy rain fell
early in the week in North Carolina where Wanchese received 8.10 inches from
Sunday afternoon to Monday night, June 21 and 22. Hail as large as baseballs fell
at Bethlo, Florida, Tuesday afternoon. On Wednesday heavy thunderstorms became
general from the central Great Plains to the western gulf coast. Palacios, Texas,
received 3.96 inches Wednesday forenoon when 4.50 inches fell at Ottumwa, Iowa.
More torrential rains fell in the afternoon with Corpus Christi, Texas, receiving
4.72 inches and Memphis, Tennessee, 2.28 inches. Much needed rain fell in all
parts of South Carolina. One of the heaviest weekly totals, 6.58 inches, fell
at Sumter, South Carolina. Strong winds raked western Montana late Saturday and
early Sunday. High winds raised clouds of dust in the agriculatural areas of the
Southwest.
TEMPERATURE: The week began sunny and pleasant especially over the North Central
States. Minimums were mostly in the 50's from the northern Rocky Mountains to New
England and as far south as the central Great Plains. Warm humid weather pre-
vailed over the Deep South with temperatures ranging from the 70's in the morning
to the 90's in the afternoon. The West warmed early in the week and | the heat
intensified as each day passed. Miles City, Montana, registered 100° or higher.
By Thursday numerous locations in the Southwest set new high-temperature records.
Afternoon maximums at Thermal and Blythe, California, reached 122° and Needles
recorded 121°. In Arizona, Phoenix registered 116° and Flagstaff 95°. The extreme
heat spread eastward. By Sunday, 100° maximums were common over the central Great
Plains from Grand Forks, North Dakota, to Wichita Falls, Texas. Almost all areas
in Nebraska and Kansas warmed to 100° or higher on Sunday. Meanwhile, cool
temperatures became general over the Northeast with minimums tumbling to the 40's
and low 50's as far south as Kentucky and Virginia. Weekly temperatures averaged
above normal from the Pacific Ocean to the northern and central Great Plains
and below normal from Texas to New England. Much of the Northeast averaged 3° to
8° cooler than normal. (Summary supplied by Environmental Data Service, ESSA.)

ARMYWORM (Pseudaletia unipuncta) - NEBRASKA - Adults light at light traps in
Lancaster County area. (Keith, June 19). IOWA - Larvae averaged less than 1 per
25 sweeps in bromegrass and oats in Harrison County and in oats in Woodbury
County. Visual check in bromegrass in Woodbury County showed 1 per square yard
or less on June 24. In central area, 90 percent of larvae observed June 23-25
parasitized by tachanids. Braconids noted under windrowed hay. (Iowa Ins. Sur.).
Larvae one-fourth to one inch long in bromegrass at Ankeny, Polk County, June
18. Nearly 50 percent parasitized. This occurrence nearly normal; not observed in
1969. (Iowa Ins. Inf.). SOUTH DAKOTA - Infestations found in 9 counties to date.
Mostly on rye with some winter wheat. Most larvae small. Larvae increasing in
Brookings County. Some parasite activity. Adults numerous first half of June;
another heavy larval brood may occur by mid-July. (Jones). MINNESOTA - Moth
collections in blacklight trap much lighter, and larvae still light. Larvae 2-3
per square foot in parts of ryefield in Lincoln County. Small grain should be
watched closely in west-central and northwest districts for larvae from moth
flights of last 2 weeks. Other areas appear past greatest danger although second
generation may be problem in late July. (Minn. Pest Rpt.). WISCONSIN - Larvae
heavy near Arcadia, Trempealeau County; damage minimal; mostly last instars in
corn. Very few larvae found along margins of peafields, but conditions right
for another outbreak, since adult flights increasing. (Wis. Ins. Sur.).
MICHIGAN - Larvae damaged wheat, timothy, and some corn in Cass County. Virus
disease killed many larvae as of June 22, and undoubtedly keeping numbers down
this year. (Ruppel). Moth collections minimal at all blacklight stations.
Last instars in small grains, numbers still below problem level. (Newman,
June 22). INDIANA - Large increase of adults in southwest district light trap
week ending June 20, and more recently in northwest district blacklight trap.

EUROPEAN CORN BORER (Ostrinia nubilalis) - NEW YORK - Egg laying and hatch
started early week of June 8 and continuing at heavy rate in Monroe, Orleans, and
Genesee Counties. Moths not waiting for corn to reach 7 to 8-leaf stage. (N.Y.
Wkly. Rpt., June 22). DELAWARE - Late instars in early planted corn, adults 1-2
per night in blacklight traps in Kent and Sussex Counties. (Burbutis, Kelsey).
MARYLAND - First-generation larvae pupating in Somerset, Wicomico, and Worcester
Counties in earliest sweet corn. Expected to remain heavy throughout Eastern
Shore production areas, where infested stalks ranged as high as 10 percent in
many fields. Heaviest, averaged 82 percent in 16 acres of field corn, in central
= Aas
area near Thurmont, Frederick County. (U. Md., Ent. Dept.). VIRGINIA - European
corn borer larvae damaged corn in Amelia County June 19. (Roberts). INDIANA -
Averaged less than one per plant on 14 percent of 30-inch plus corn in central
district. Mostly early instars with occasional whorl penetration. Occasional
adults still seen. (Meyer). MICHIGAN - Moths peaked at all blacklight stations:
609 at Lenawee County station and 586 at Livingston County station. About 60
percent of hatch completed; egg laying will peak within 10-14 days. Food will be
sufficient for peak of hatch. (Newman, June 22). WISCONSIN - Leaf feeding light
in southern and southwestern areas; highest 20 percent. (Wis. Ins. Sur.).
ILLINOIS - Not too severe in fields examined. About 5-10 percent of corn mature
enough for high larval survival. About 10-20 percent of these fields have enough
borers to warrant controls. Few eggs still deposited in area north of St. Louis,
south of Rock Island, and west of U.S. Highway 51. Borers entering stalks. Light
in east area; few fields require protection. (Sur. Bull.). MINNESOTA - Moth

Larvae ranged 0-16 per 100 plants. First and second instars in south counties.
(Minn. Pest Rpt.). IOWA - Larvae per 100 plants in corn with Sudan grass 22 and
2 in cultivated corn. Forty percent of early corn at Ankeny, Polk County. showed
leaf feeding in whorls June 18. Larvae averaged 60-65 per 100 plants with 80
percent first instar and 20 percent second instar. (Iowa Ins. Inf.). MISSOURI -
Leaf feeding averaged 83.5 percent on 48-inch corn in southwest area field.
Larvae averaged 3.6 per plant. Instars ranged 10 percent second, 80 percent
third, 10 percent fourth. Chemical controls applied. Leaf feeding on 51 percent
of plants on 38-inch corn in 2 fields. Larvae averaged 2.4 per plant; 40 percent
second and 60 percent third instar. (Munson).
NEBRASKA - European corn borer very light, less than 1 percent of plants infested
in 2 fields near Ceresco in Saunders County. (Campbell, Keith). Flights peaked
at Lincoln, Lancaster County, June 6, at Concord, Dixon County, June 8. Catches
at Concord heavy, with 643 moths. First-brood damage likely in area on early
planted corn. (Berogan, Keith). KANSAS - Infested 5-20 percent of corn in
Jefferson, Atchison, Brown, Jackson, and Shawnee Counties. (Iselin).
BLACK CUTWORM (Agrotis ipsilon) - WISCONSIN - Damage appearing on corn in
scattered fields in Dane, Dodge, Fond du Lac, Green Lake, Dunn, Walworth, and
Racine Counties. Damage varies considerably even within field and in most cases
restricted to low areas and along margins. Middle plantings appear hardest hit.
(Wis. Ins. Sur.). ILLINOIS - Apparently decreasing in corn. Some problems in
control; present methods and insecticides vary in results. (Sur. Bull.).
CUTWORMS - NEBRASKA - Agrotis ipsilon (black cutworm) and Feltia subgothica
(dingy cutworm) still damaging in east, southeast, and central areas. Dingy
cutworm averaged 5.3 per 10 square feet in untreated areas in corn near Wahoo,

Determined by M. Gardner and W. Bauer. This is a new State record. The 0.25-inch
larvae feed externally on growing tips of Sitka spruce (Picea sitchensis). Larvae
work under bud scales which form a terminal cap which remains in place causing
new needles to balloon. New growth develops somewhat normally, but some webbing
causes bunching of several needles to stand out along new shoot. Later needle
- 449 -

1969 CEREAL LEAF BEETLE INFESTATION AND OATS CROP LOSS SURVEY aly
M. Curtis Wilson 2/, Robert E. Treece 3/
: and Richard E. Shade 2/
The cereal leaf beetle (Oulema melanopus (L.)) survey, designed to estimate larval
populations and loss to the oats crop from foliar feeding damage, was conducted
for the third season in 1969. Previous reports have been published by Wilson’ and
Treece (1968), and Wilson, Treece, and Shade (1969). In the last report (CEIR
19(23) :409-417, 1969), it was pointed out that the cereal leaf beetle had not
only spread rapidly, but was building up populations at a massive rate, particu-
larly in eastern areas 300 to 500 miles distant from the focal point of initial
infestation. An expanded survey of 222 counties (Illinois 12, Indiana 59, Michigan
58, Ohio 65, Pennsylvania 16, West Virginia 5, Wisconsin 4, and Ontario 3) con-
firmed this in 1969.
Data from this survey are tabulated in four tables. Table 1 summarizes losses from
the cereal leaf beetle from 1967 through 1969. Table 2 shows a breakdown of losses
by State districts. Districting is basically the same as that used by the
Statistical Reporting Service. Some districts, however, have been subdivided into
A and B areas according to infestation levels. Where counties that occur in the
district are not listed, they have been excluded because cereal leaf beetle popula-
tions were generally too low to be of economic significance. In Table 3, a
comparison of infestation estimates for each of the three years the survey was
conducted is tabulated. Some general infestation comparisons based on State
averages are shown in Table 4.
Surveys continue to reveal that ecological conditions have been more favorable
for cereal leaf beetle buildup from north-central Indiana eastward than they have
been in a westward direction from the same point (La Porte County). This is
apparent in all tables. Losses occurred in Pennsylvania (Tables 1 and 2) after
only two years of known infestation, while after six years in western Indiana and
eastern Illinois, there are still no damaging populations.
The comparisons in Table 4 show that population levels east and southeast of La
Porte County in north-central Indiana are comparable to the high populations of
Michigan, but south and west they appear static at low numbers. On the otherhand,
in an eastward direction, five counties in West Virginia attained populations one
year after detection equivalent to those found in western Indiana after six years.
In western Pennsylvania counties, after two years, populations were threefold
those in western Indiana. Comparative infestation levels are shown on the map
on page 468.
1/ The following agencies cooperated to complete this survey: USDA, Plant
~ Protection Division; Indiana State Entomologist's Office, Purdue University;
Ohio Department of Agriculture, Ohio Agricultural Research and Development
Center; Michigan State University; Pennsylvania Department of Agriculture,
Pennsylvania State University; Wisconsin Department of Agriculture; and the
University of West Virginia.
Estimates of oats acreage from which losses were calculated were obtained
from the USDA Statistical Reporting Services of Indiana, Ohio, Michigan, and
Pennsylvania. The value of oats was estimated at 59¢ per bushel by the
Statistical Reporting Service Office at Lafayette, Indiana.

With the exception of Indiana, cereal leaf beetle infestations increased and
losses were greater in all of the States that had previously suffered losses.
In Indiana and Illinois there was a downward trend in populations. In Illinois
and parts of western Indiana they were sufficiently low that even traces of
damage were not detected by this survey as in previous years.
In contrast, conditions in an eastward direction from Indiana have been so
favorable for the cereal leaf beetle that the loss in the oats yield increased 44
percent in 1969 over 1968. All population estimates are calculated from foliar
feeding data and are based on consumption of approximately 20 percent of the
foliage per larva per stem (Wilson et al, 1969). The index for loss of 3.17
bushels of oats per larva per stem infestation used in the 1968 report was also
applied to the 1969 data.

WEATHER OF THE WEEK ENDING JULY 6
HIGHLIGHTS: A warming trend occurred over the West and weekend cooling ended the
sweltering heat in the East. Moist areas received less than normal precipitation.
PRECIPITATION: Light showers occurred in the Northwest. Strong hot winds raised
Clouds of dust in parts of Arizona and the central Great Plains and caused fur-
ther depletion of the soil moisture. Snow fell in parts of the northern Rocky
Mountains Tuesday morning accumulating to 2 inches at West Yellowstone, Montana.
Violent weather occurred from the central Great Plains to the Atlantic Ocean on
Thursday and from southeastern Texas across the Deep South to Georgia on Friday.
The violent weather included severe thunderstorms with scattered hail and strong
winds, and a few tornadoes. Weekly rainfall totals over the western half of the
Nation ranged mostly from none in most of the Southwest to about 0.10 inch in
the Northwest. Over the eastern half, weekly totals ranged generally from about
0.25 inch to 1.25 inches. A large area from Missiouri to Texas, Alabama, and
Mississippi, received no rain or only light sprinkles. A few spots in the East
received over 2 inches of rain during the week.
TEMPERATURE: Temperatures averaged below normal in the northern Rocky Mountains
and the Great Basin, above normal in the central Rockies and southwestern deserts,
and near normal in most other areas. A warming trend occurred in the Northwest
with afternoon temperatures increasing from the 60's and 70's on Monday to 100°
in desert areas of Washington. Sharp cooling brought subfreezing weather to some
areas along the western slopes of the Rocky Mountains on one or two mornings
early in the week. West Yellowstone, Montana, registered 28° and Bryce Canyon,
Utah, 307 Tuesday morning. The southwestern deserts remained hot throughout the
week. Maximum temperatures at Blythe, California, averaged 108°. Sweltering heat
covered the northeast quarter of the Nation, from Minnesota and Iowa to the
Atlantic Ocean early in the week but much cooler and less humid weather occurred
over the weekend. Maximum temperatures reached the 90's over wide areas each
afternoon until Thursday but dropped to the 60's and 70's by Saturday. Minneapo-
lis, Minnesota, registered 90° Thursday afternoon but no higher than 71° the
following day. A warming trend over the Central and Southeast pushed maximum
temperatures above 100° on Thursday and Friday. Temperatures dropped sharply by
Saturday. Maximums at Chattanooga, Tennessee, on Friday and Sunday were 102 and
83°, respectively. Minimum temperatures dropped sharply, also, from the 70's
Saturday morning to the 50's by early Monday. (Summary supplied by Environmental
Data Service, ESSA.) For 30-day forecast see page 487.

WEATHER OF THE WEEK ENDING JULY 13
HIGHLIGHTS: Typical summer heat prevailed over much of the Nation. Scattered
thundershowers, some locally heavy, occurred from the Rocky Mountains to the
Atlantic Ocean.
PRECIPITATION: High pressure and mostly clear rainless skies prevailed over
most of the Nation early in the week. Scattered thundershowers, some accompanied
by hail and high winds, occurred across mid-America early Wednesday. At midweek
nighttime and early morning showers fell across the warm, humid Southland and
from the eastern Great Lakes to the Middle Atlantic States. Locally heavy showers
occurred Thursday afternoon along the gulf and Atlantic coasts. Washington, D.C.,
National Airport received 4.69 inches Thursday afternoon and evening, flooding
some roads and underpasses. Rainfall totals west of the Rocky Mountains were
generally only a small fraction of an inch and many far-western stations
received no rain. Heavier rains fell over the Great Plains with weekly totals
mostly from 0.10 to 0.75 inch. The heaviest showers fell in southern Pennsylvania
and nearby parts of Maryland and West Virginia with a number of locations
receiving several inches of rain Thursday afternoon and evening and early Friday.
TEMPERATURE: High pressure brought mostly fair weather last week. Early morning
temperatures ranged mostly from the 50's across the Northern States to the 70's
across the South. Ocean breezes cooled the Pacific coast but hot afternoons,
typical for this time of year, were general over inland portions of the Nation
from the Canadian to the Mexician border. Temperatures reached 100° or higher
in eleven States on Wednesday afternoon. Temperatures averaged slightly below
normal along the Pacific coast, but several degrees above normal from southeastern
Washington to the southwestern deserts. Near-normal weekly average temperatures
occurred from the Great Basin to the middle Mississippi River. Most of the East
averaged slightly cooler than normal. (Summary supplied by Environmental Data
Service, ESSA.)

WEATHER OF THE WEEK ENDING JULY 20
HIGHLIGHTS: Temperatures ranged widely soaring to over 100° at some localities
in over a dozen Western and Central States to a few degrees above freezing in the
central Rockies. Spotty showers dotted much of the Nation being heavier over the
eastern half.
PRECIPITATION: Most areas in the western half of the United States received no
rain or only light sprinkles. The main exceptions included the Idaho Panhandle,
western Montana, and some mountain localities in Arizona and New Mexico where a
few weekly totals exceeded 1 inch. Showers were more generous over the eastern half
of the Nation with many small areas receiving 1 to 2 inches of rain. Hail and high
winds accompanied some of the heavier showers. Some spots in the East missed by
the rains need moisture badly.
TEMPERATURE: Ocean breezes cooled the Pacific coast last week but the heat
intensified over the western interior with the mercury reaching 100° or higher
over much of the West. Maximum temperatures Wednesday afternoon included: Ephrata,
Washington, 100°; Portland, Oregon, 102°; Boise, Idaho, 100°; Winnemucca, Nevada,
102°; Grand Junction, Colorado, 100°; Needles, California, 117°; Prescott and
Winslow, Arizona, 100° and 103°, respectively. A warm humid airmass lay over the
eastern half of the Nation through most of the week. Sharp cooling dropped
maximums near the Great Lakes late in the week. Green Bay, Wisconsin, registered
89° Friday afternoon but no higher than 74° Saturday. Greater contrasts occurred
the following day in the northern and central Great Plains. Norfolk, Nebraska,
recorded 98° Saturday but the highest temperature Sunday was 68°. Minimum tempera-
tures from the Dakotas were about 15° to 20° colder Sunday morning than 24 hours
earlier, dropping from the 60's Saturday to the 40's on Sunday. The Saturday and
Sunday minimum temperatures at Sioux Falls, South Dakota, were 63° and 45°,
respectively. Weekly temperatures averaged slightly below normal from the northern
Great Plains to the Atlantic Ocean and from southern Texas to the Florida
Panhandle and above normal over most other parts of the Nation. Parts of the
southwestern deserts averaged 6° to 10° above normal. (Summary supplied by
Environmental Data Service, ESSA.)

Lancaster County, and Concord, Dixon County, week ending July 10. Collected 428
moths at Lincoln July 7. (Berogan). SOUTH DAKOTA - Larval damage heavy in one
field of second-growth alfalfa east of Spearfish, Lawrence County. Full-grown
larvae per square foot ranged 10-15 in protected locations and 3-5 in exposed
areas. Controls applied. (Jones). WISCONSIN - Light damage in Marathon County
cornfield near Wausau. Light in sweet corn in most localities from Illinois
border north to Jackson, Pepin, and Marathon Counties. (Wis. Ins. Sur.).
MICHIGAN - Larvae heavy in field of no-till corn in Osceola County. Controls
warranted. (Ruppel, July 13). INDIANA - Blacklight trap catches July 5-11 by

ASTER LEAFHOPPER (Macrosteles fascifrons) - NORTH DAKOTA - Continues to increase,
adults and nymphs up to 2,000 per 100 sweeps in some small grain fields in eastern
counties. Range per 100 sweeps: 40-2,000 (average 645) in Cass County, 50-2,000
(averaged 475) in Traill County, and 20-400 (averaged 142) in Richland County.
Some controls applied; results poor. (Brandvik).
CORN EARWORM (Heliothis zea) - TENNESSEE - Damage moderate to heavy to whorls of
late-planted corn throughout State. Damage light to moderate to early planted
corn. (Gordon). ARKANSAS - Larvae 1 on 5-10 row feet of early blooming sorghum in
Pope County. Moths above average in cotton fields in all counties visited in upper
Arkansas River Valley. (Boyer). OKLAHOMA - Heavy in corn and sorghum in Craig
County, moderate in corn in Cleveland County, and light in corn in Choctaw County
and on peanuts in Caddo County. (Okla. Coop. Sur.). NEBRASKA - Moth catches light
at Lincoln, Lancaster County, and Concord, Dixon County. (Roselle). UTAH - Larvae
moderate in Washington County; moths in early silked corn in northern counties.
(Knowlton).
CORN LEAF APHID (Rhopalosiphum maidis) - UTAH - Very light on field corn in Utah
and Cache Counties. (Davis, Knowlton). Conspicuous in many barley fields in Iron
County; 500 acres sprayed. (Sjoblom). Conspicuous in some Millard, Beaver, and
Cache County barley. (Knowlton). NEW MEXICO - Generally medium to heavy in most
grain sorghum-growing areas. Many growers treating. (N.M. Coop. Rpt.). TEXAS -
Infestations in High Plains still widespread on sorghum but declined in most
headed sorghum fields. Little evidence of injury observed in fields heavily
infested prior to heading. (Rummel, Clymer). OKLAHOMA - Very heavy in many
sorghum fields in southwest area. Light to heavy in Texas and Cimarron Counties.

County fields. (Roselle, Keith). Found on most corn plants in 6 Lincoln County
fields. (Campbell). ILLINOIS - Corn leaf aphid numerous in some fields; may seem
to "explode" within next 14 days. Limited surveys indicate possibility of serious
problems. Predator numbers low, but disease killing some aphids, and high tempera-
tures slowed reproduction. Corn in late-whorl and early tassel stages appears to
have most aphids. Early fields in which pollination already occurring should
escape damage. (Sur. Bull.).
WISCONSIN - Corn leaf aphid increasing, and large colonies evident on individual
corn plants. In fields surveyed, fewer than 10 percent of plants infested and
colonies generally comprised of less than 300 aphids. Heavier in few fields and

reported in Cottle County. Continued to infest grain sorghum throughout Blacklands
area, light to medium in some fields. (Rummel et al.). OKLAHOMA - Increased,
ranged up to 1,000 per leaf in some older grain sorghum in Jackson County.

plant in scattered areas in Texas and Cimarron Counties. (Okla. Coop. Sur.).
KANSAS - Developing in widely scattered areas of State. Winged forms present and
colonies developing on underside of lower leaves in Wabaunsee County. Some in
Doniphan and Thomas Counties. Up to 100 per leaf from one field in Finney County.

per plant and egg masses common in fields surveyed. A braconid (Lysiphlebus
testaceipes) very light, less than 1 percent of greenbugs parasitized. If drought
conditions continue and predators do not increase rapidly, serious problem may
develop. (Keith). SOUTH DAKOTA - Several thousand per plant in 50 acres of grain
sorghum near Meckling, Clay County. Sorghum expected. to head out in 10 days.
Treatments to be applied. Other infested fields required treatment in northern
Clay County. Trace on sorghum sampled near Mitchell, Davison County, and near

WEATHER OF THE WEEK ENDING JULY 27
HIGHLIGHTS: Temperatures averaged slightly cooler than normal over the western
and eastern thirds of the Nation and much cooler than normal over the central
portion. Tropical storm Becky brought rains almost daily to portions of the
Southeast.
TEMPERATURE: Cold air poured into the North-central States early in the week
dropping temperatures sharply. Monday morning readings plummeted to the 40's
and 50's as far south as the northern portions of Kansas and Missouri. Spring-
field, Missouri, registered 44° early Tuesday morning. These temperatures are
near normal for September but are about 15° below normal for July. Warm humid
weather continued over the Deep South and hot weather persisted in the South-
west. Temperatures continued near normal over the West at midweek. Over the
East, however, cool air continued to pour southward. Afternoon temperatures re-
mained in the 70's and low 80's over a large area from Minnesota to New England
and southward to the central gulf coast. Alexandria, Louisiana, registered The)
Wednesday afternoon in contrast to the 92° maximum Monday. Afternoon maximums in
the 70's are common over the Deep South in October. Late in the week, a High
pressure area remained centered over the central Appalachians. This system
brought the return of high temperatures and increased relative humidity to the
eastern half of the Nation. By the weekend, maximums in the upper 80's and lower
90's were common from Minnesota to New England. Weekly temperatures averaged
above normal over most of California, western Nevada, southwestern Arizona, and
New England, and below normal over the rest of the Nation. Parts of the central
Great Plains averaged.6° to 10° cooler than normal.
PRECIPITATION: Generous showers fell early in the week along the gulf and
Atlantic coasts while lighter, more scattered showers fell in the Southwest
Interior, the Great Basin, and the northern Rocky Mountains. Scattered showers
occurred over the northern and central Great Plains late in the week and light
rains began in the Far Northwest on Sunday. Tropical Storm Becky was responsible
for most of the other precipitation last week.
Weather continued on 547.

west-central 45. (Huber).
ASTER LEAFHOPPER (Macrosteles fascifrons) - MINNESOTA - Remains heavy, ranged
500-1,500 per 100 Sweeps, in west-central and northwest districts. Trace aster
yellows disease in some flax. Expect higher than normal infection in these
districts later this season. (Minn. Pest Rpt.). WISCONSIN - Mass flight night of
July 16. Controlled in commercial plantings of lettuce, but about 4 percent of
early crop affected by aster yellows. Leafhoppers 3 per 10 sweeps in adjacent
fields of mint. (Wis. Ins. Sur.).
CORN EARWORM (Heliothis zea) - NEW YORK - Some fourth instars found in about 1,000
ear tips in various Ulster County fields on July 17. First moth in Poughkeepsie
trap on July 20. (N.Y. Wkly. Rpt.). DELAWARE - Freshly emerged adults 3 per night
in blacklight trap collections in most areas. (Burbutis et al.). MARYLAND -
Heaviest adult flights at Salisbury, Wicomico County, and Centreville, Queen Annes
County; averaged 2-3 per night in blacklight traps. Flights expected to increase
rapidly throughout Eastern Shore next 21 days. (U. Md., Ent. Dept.). VIRGINIA -
Expect 50 percent infestation on sweet corn in Holland area, Nansemond County,
and no danger at this time to soybeans, based on light trap catches. (Allen).
WISCONSIN - About 4 pércent of ears of early planting of sweet corn infested in
western Dane County. Infestations reported in Portage and Walworth Counties.
(Wis. Ins. Sur.). TENNESSEE - Moderate to heavy damage on whorls of late-planted
corn and on ears of earlier-planted corn in many central areas. Control in some
cases not effective. (Gordon). ARKANSAS - Averaged less than one larva to 10 row
feet of sorghum. (Boyer). OKLAHOMA - First to third instars increased in alfalfa
in Jackson County. Ranged 5-7 per 10 sweeps in alfalfa in Muskogee and Wagoner
Counties. Averaged 1 per ear in corn in Greer County. Moderate in corn and sorghum
in Craig County, and light in corn in Choctaw County. (Okla. Coop. Sur.).
NEBRASKA - Infested 40 percent of sweet corn ears examined in planting at Lincoln,
Lancaster County. (Keith). IDAHO - Incidence in cornfields greater than usual in
Canyon County. Average 1-12 percent in some fields indicating heavy ear infesta-
tion likely. (Homan). UTAH - Moderate in Washington County sweet corn. (Knowlton,
Huber). ARIZONA - Larvae averaged 2 per ear of field corn at Safford, Graham
County. (Ariz. Coop. Sur.).
CORN LEAF APHID (Rhopalosiphum maidis) - ALABAMA - Found on corn and grain sorghum
in all fields examined throughout State. Corn stunt virus and/or maize dwarf
mosaic heavy in most corn in Shelby and Bibb Counties. Noticeable in corn through-
out most of north area. Estimate corn yields will be reduced by 75 percent in more
heavily infested fields in Bibb County. (Clarke et al.). MARYLAND - Corn leaf
aphid infested isolated cornfields throughout Eastern Shore, heaviest in 30 acres
near Trappe, Talbot County, and 15 acres near Kennedyville, Kent County. Averaged
10 percent of stalks infested. (U. Md., Ent. Dept.). INDIANA - Colonies in about
half of cornfields checked in northern fourth of State. Ranged 4-44 percent of
plants infested. Colonies ranged small to medium, and mostly confined to whorls.
(Meyer). ILLINOIS - Percent plants infested heavy. No increase from previous
reports due to cool rainy weather in northern, western, and southern areas. No
threat yet. (I1l. Ins. Rpt.). WISCONSIN - Colonies generally still low in most
fields but some corn heavily infested in central areas. Appearance of large

TROPICAL STORM BECKY: Becky began quite humbly as a weak tropical depression
that formed in the central Atlantic Ocean about 750 miles east of the Lesser
Antilles late on July 14. The depression moved westward into the Caribbean,
causing some shower activity over Cuba and the Florida Straits. Once reaching
the Gulf of Mexico, the depression begans to intensify rapidly, and by afternoon
on the 20th, a poorly organized tropical storm had formed. Becky moved northward
and continued to intensify, Becky continued northward toward the Florida Panhandle
with just below hurricane-force winds near the center, and hurricane warnings
were issued from Fort Walton to Point St. Joe, Florida. The storm remained poorly
organized, however, and by 3 a.m. on the 22d she had begun to weaken and turn
slightly towards the northeast. At 5 a.m. on the 22d, hurricane warnings for the
Florida coast were discontinued. Gale warnings remained in effect from Panama
City to St. Marks, Florida. Tropical storm Becky moved inland near Point St. Joe
at 7 a.m. on the 22d, bringing heavy rain and squalls to the Florida Panhandle.
A total of 8.16 inches of rain was dumped on Tallahassee, which also recorded a
sustained 29 m.p.h. wind with gusts to 44 m.p.h. A tornado destroyed three
houses in Panacea, Florida, but no injuries were reported, and a high tide of
3 feet above normal was recorded at Panacea. Becky rapidly became extratropical,
but the remnants of the storm continued northward bringing rain to the south-
eastern and Middle Atlantic States. Flash flood warnings were issued for the
Appalachian region. The storm moved through Georgia, Tennessee, and Kentucky,
and by the morning of the 24th she had completely dissipated over Indiana,
leaving behind a great deal of moisture. In Georgia, 3.34 inches of rain fell
in Augusta and a tornado demolished two houses in Jefferson County, injuring one
person seriously. Columbia, South Carolina, had 2.72 inches of beneficial rain
and no adverse effects from the storm. Elsewhere the rainfall was widespread
south of the Great Lakes and east of the Mississippi River. (Summary supplied by

WEATHER OF THE WEEK ENDING AUGUST 3
HIGHLIGHTS: Hot humid weather continued through most of the week in the Central
and East. Spotty nighttime thundershowers brought little relief from the heat
and humidity.
PRECIPITATION: Widely scattered showers and thunderstorms dotted the Nation last
week, They occurred principally over the northern and southern Rocky Mountains
early in the week from the northern Great Plains to New England and across the
Deep South at midweek, and over the weekend. Gusty winds and hail accompanied
some of the nighttime thunderstorms in the central and eastern parts of the
country. A few tornadoes occurred but caused relatively little damage. Weekly
totals ranged widely from none or only light sprinkles to near 1 inch over the
West and from sprinkles to 2 inches or so over the East. A few spots in the East
received more than 2 inches.
TEMPERATURES: Cool weather prevailed only along the northern Pacific coast last
week with temperatures reaching the 60's in the afternoons and dropping to the
50's at night. The Southwest continued hot with nighttime temperatures in the
upper 70's and 80's and daytime maximums from the 90's to 110° or more, Maximums
in the southwestern deserts averaged about 110°. Summer heat and high humidity
continued in the stagnant air that lay east of the Rockies. At midweek,
temperatures from the Great Plains to the Atlantic Ocean were mostly in the upper
80's and 90's except 100° or warmer over the central Great Plains. Nighttime
minimums ranged from the 60's in the northern border States and Appalachian
Mountains to the 70's elsewhere, The high relative humidity in this large stagnant
airmass added to the discomfort caused by the high temperatures. Cooler drier air
moved over the Northeast Sunday. Weekly average temperatures were below normal
northwest of a line from Bakersfield, California, to Fargo, North Dakota, and
above normal elsewhere, A large area from the central Great Plains to New England
averaged 3° to 9° above normal. (Summary supplied by Environmental Data Service,
ESSA).

WEATHER OF THE WEEK ENDING AUGUST 10
HIGHLIGHTS: Central and south Great Plains in the far southwest continued hot.
Some relief from heat and humidity occurred in the Northeast. Flood producing
thundershowers fell in parts of Iowa, Missouri, North Carolina, and Georgia.
PRECIPITATION: Hurricane Celia dumped some heavy rains in the southern portions of
Texas and New Mexico early in the week. Moderate to heavy Showers also fell in
other parts of the country. More scattered in the central and southern Rocky
Mountains, but not so scattered from the middle and southern Mississippi River
Valley to the middle and southern Atlantic coast. Heavy rains in Iowa, 4 to 7
inches at some spots, caused lowland flooding along some creeks and rivers on
Wednesday. The weekend brought scattered moderate to heavy showers from Missouri
and Arkansas to the western portions of the Carolinas and southward to the Florida
Peninsula, Many streams in North Carolina and in the Savannah area of Georgia
overflowed their banks. Precipitation was light over the western half of the Nation
with many western areas receiving no rain or only light sprinkles.
TEMPERATURE: Typical summer heat continued over much of the Nation last week.
Maximum temperatures reached the 60's along the Pacific coast but climbed much
higher over the rest of the country. The southwestern deserts and the southern
Great Plains warmed to 100° or higher on almost everday. Havre and Miles City,
Montana, registered 100° Wednesday and Goodland, Kansas, recorded 108° Thursday.
Kansas, Oklahoma and nearby parts of neighboring States averaged 3° to 9° warmer
than normal, The mercury soared to 114° at Thermal, California, Thursday. The
Deep South continued hot and humid with maximums in the 90's on most afternoons,
Wednesday afternoon readings included 99° at Macon, Georgia, and 96° at Palm Beach
and Miami, Florida. Sunny weather with a cooling trend occurred from the northern
and central Great Plains to New England. Temperatures from northern Minnesota to
Upper Michigan dropped to the 30's and 40's Tuesday morning but bounced up to
the 80's by Thursday afternoon, A large area from Iowa to New York averaged 3°
to 6° cooler than normal. The week ended with warmer weather returning to the
Northeast. (Summary supplied by Environmental Data Service, ESSA.)

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE
ARMYWORM (Pseudaletia unipuncta) - SOUTH CAROLINA - Economic infestations reported
from Aiken to Chesterfield Counties; particularly damaging to Coastal Bermuda
and other grasses in pastures and lawns. Large scale control efforts underway.
Equipment and chemicals adequate. Problem expected to continue and infestations
probably will be appearing to the north. Conditions favorable for development
because of rainy weather following extensive dry period. (Nettles). Worst out-
break in 7 years in Columbia area of Richland County. Up to 2,000 acres of lawns
and pastures damaged. Over 500 calls received during week ending August 7.
(Bailey). NEBRASKA - Occasional larvae in corn ears in Hall County; averaged less
than 1 percent in 20 fields. Larvae fourth to fifth stage. (Keith, Berogan).
BEET LEAFHOPPER (Circulifer tenellus) - CALIFORNIA - Curly top 100 percent in
about 2,500 acres of sugar beets in Antelope Valley, Los Angeles County. Damage
moderate to severe. Worst year of past 8 years. Cold weather, replanted fields,
and early flights favored pest. (Cal. Coop. Rpt.).
CORN EARWORM (Heliothis zea) - NEW HAMPSHIRE - Third-stage larva found in ear of
sweet corn in Hillsborough County August 3. Determined by J.G. Conklin. First
collection of season. (Blickle). NEW YORK - No larvae in several hundred untreated
ear tips examined in sweet and field corn. One moth taken August 1 at Poughkeepsie,
Dutchess County. (N.Y. Wkly. Rpt., Aug. 3). MARYLAND - Well below 1969 heavy
levels at this time. Heaviest on 26 percent of 40-acre stand on Eastern Shore near
Ruthsburg, Queen Annes County. Very low in ears this season, averaging below 10
percent throughout Eastern Shore area. (U. Md., Ent. Dept.). VIRGINIA - Heavy
population damaged 70 acres of corn in Goochland County. (Truett, July 30).
Infested 2 percent of ears of field corn in Charlotte County. (Hendrick). Moth
catches remain light but unsprayed sweet corn may show much damage. (Allen).
FLORIDA - Adults heavy on Bahia grass seed heads at Quincy, Gadsden County.
(Greene). Adults abundant in fields at Gainesville, Alachua County. (Mead). Very
light on soybeans, 7 larvae per 10 row feet, at Gainesville. (Whitcomb). ALABAMA -
Flights heavy througout northern area. Very heavy increase in larvae throughout
northern area on silking corn; infestation 50-100 percent. (McQueen). ARKANSAS -
Principal pest of sorghum in northeast area. Ranged 3.7-4.3 per row foot in
untreated fields in milk to dough stages in Independence County; planted in 38-inch
rows. Averaged 3.2 per row foot in Jackson County field planted in 30-inch rows
and sorghum in same stages of development. Larvae 0-0.25 per row foot in mature
fields in these counties. Control ineffective in treated field in Independence
County; larvae 2.6 per row foot. No larvae found in another field treated with
different material. Larvae averaged 0.2 per row foot in treated field in Jackson
County. (Boyer, Jones). INDIANA - Late instars in only one field in southern
districts. In fewer than 1 of 50 ears of early planted field corn. (Meyer, July
31). WISCONSIN - Few adults in blacklight trap at Arlington. Larvae reported in
sweet corn in few southeast area localities.» (Wis. Ins. Sur.). NEBRASKA -
Averaged less than 1 percent in 20 cornfields in Hall County. (Keith, Berogan).
KANSAS - Generally lighter than on silking corn. Averaged one per ear in Osborne
County, but none in fields in early silk in Stafford or Grant Counties. (Gates,
Aug. 5). UTAH - Light to moderate on corn in Weber (Boyer), San Juan and Grand
(Jones), and Cache Counties (Knowlton).
CORN LEAF APHID (Rhopalosiphum maidis) - NEW YORK - Prevalent in most early planted
sweet corn. Wingless and winged forms abundant on emerging tassels of sweet corn
in Hudson Valley. Honeydew slick with sooty mold on ears as infested tassels rise
above ears. (N.Y. Wkly. Rpt., Aug. 3). MARYLAND - Remained light on corn statewide
but infestation up to 50 percent in 75-acre field at Howell Point, Kent County.
Infested up to 72 percent of 6-acre field near Thurmont, Frederick County.
Infestations above 1 percent in 1 of 30 fields statewide. (U. Md., Ent. Dept.).
INDIANA - In only few fields of field corn in southern districts; mostly in
southeast district. Infested 72-94 percent of plants. (Meyer, July 31). ILLINOIS -
Heavy in some corn in east-southeast area and occasional field in other areas;
heaviest in pretassel corn. Populations light generally; decreased in many fields
as tassels emerged. No widespread outbreak expected. (Sur. Bull.). WISCONSIN -
- S76 -
Corn leaf aphid very heavy in some fields. Up to 100 percent of fields infested
in some areas; colonies of 500+ aphids per plant on 80 percent of plants in few
fields. Lady beetle adults and larvae and syrphid larvae numerous and preying on
aphids in all areas checked from Rock County to Door County. (Wis. Ins. Sur.).
NEBRASKA - Most aphids gone from fields examined in Lincoln County. (Campbell).
OKLAHOMA - Generally decreasing in panhandle counties. Most fields checked
averaged less than 500 per plant. Heavy on Craig County sorghum. (Okla. Coop.
Sur.). ARIZONA - Averaged 30 per 2-foot high sorghum boot in Yuma Valley, Yuma
County. (Ariz. Coop. Sur.).
GREENBUG (Schizaphis graminum) - NEBRASKA - Building up, ranged 100-6,000 per
plant in 12 fields in Lancaster, Gage, Jefferson, Thayer, Webster, and Franklin
Counties. Destroyed 4-acre field of grain sorghum about 10 inches in extended
leaf height in Saunders County; averaged 1,000 per leaf on 4 lower leaves in
another field. Beneficial insects increasing slowly. Lady beetle adults and
larvae averaged 2 per plant in most fields. Lysiphlebus testaceipes (a braconid)
parasitism less than 1 percent. Greenbug flights so heavy in Some areas that
plane windshields cannot be kept clear. Spraying increasing, but not extensive
due to drought damage to grain sorghum in east, southeast, and central areas.
(Keith et al., July 31). Currently declining in grain sorghum. Ranged 25-1,000,
averaged about 300 per leaf in 3 fields in Platte, Butler, and Saunders Counties.
In Gage and Lancaster Counties, ranged 10-275 (averaged about 50) per leaf in 6
fields. Most decline in east and southeast attributable to hard, driving rain,
accompanied by 50-100 mile per hour winds over weekend. Parasites and predators
continue to increase. L. testaceipes destroyed 5-35 percent or more of remaining
aphids in fields examined in east and southeast. Still many fields not out of
danger. (Keith et al.). Economic in 1 of 3 fields surveyed in Lincoln County.
(Campbell). KANSAS - Most fields in State infested. Average counts per sorghum
plant July 25-31 by county: Kearny 570 in one field, 90 in nearby field, Finney
240 in 1 field, beneficial insects extremely scarce in these 3 fields; Meade 250
in field in boot stage, mostly lady beetles or lacewing eggs on 80 percent of
plants examined and little doubt field under natural control within few days.
Seedlings up to 10-inch plants most critically infested and will be dead by August
12 in many cases if not treated. Beneficial insects appeared to decrease
greenbug counts in several cases in eastern area. In many cases, wilting plants
on dryland fields not supporting heavy greenbug populations. Irrigated sorghums
in west most likely will represent greatest amount of acreage needing treatment
next 7 days. (Gates, Aug. 5).
ARKANSAS - Greenbug survey of sorghum negative in Independence County. Found at
rate of one colony per 5 blades in Jackson County; this is a new county record.
(Boyer, Jones). OKLAHOMA - Continues to increase on sorghum in panhandle counties.
Up to 2,500 per plant in some fields. Scattered fields being sprayed. Heavy in
scattered fields in Payne and Ottawa Counties. (Okla. Coop. Sur.). NEW MEXICO -
Heavy on grain sorghum in Hidalgo County. Controls applied. (Hitson). Heavy on
some sorghum and broomcorn in Roosevelt County. (Durkin). ARIZONA - Averaged 25
per 100 sweeps in 4 sorghum fields in Yuma Valley, Yuma County. (Ariz. Coop.
Sur.). COLORADO - Up to 20 per plant in sorghum field in southwest Morgan County.
Damage very light. (Johnson).
POTATO LEAFHOPPER (Empoasca fabae) - MARYLAND - Averaged less than 5 per sweep of
alfalfa statewide; averaged 50 per sweep at Trappe, Talbot County. Ranged 20-30
per sweep on 50 acres at Chestertown, 25 acres at Howell Point, and 45 acres at
Coleman, Kent County. Heaviest in central counties, 7-25 per sweep in Thurmont,
Frederick County. (U. Md., Ent. Dept.). MICHIGAN - Very heavy on red kidney beans
in Kent County. (Cress, Aug. 3). Damaging numbers of adults and nymphs in few
fields of Clinton County beans. Adults common on alfalfa in Clinton County and
on beans in Huron, Ingham, and Tuscola Counties. Could increase to severely
damaging numbers very quickly, especially with drier weather. (Ruppel, Aug. 3).
WISCONSIN - Averaged 12 per 10 sweeps in alfalfa in Kewaunee County; ranged
4-35 per sweep in central and southern counties. Apparent damage severe in
portions of some fields. Spraying of second crop probably would not be economically
justified in Sauk County due to large yields of first-crop hay. Populations
= Oi =
variable in beans and potatoes. ''Hopperburn" severe on small Dane County potato
planting after adjacent alfalfa cut. Few found in Waushara County snap beans,
possibly due to treatment. Averaged 5 per linear foot in untreated garden plots
of beans and potatoes in Dane County. (Wis. Ins. Sur.).
SPOTTED ALFALFA APHID (Therioaphis maculata) - OREGON - Averaged less than one
per sweep at Hermiston, Umatilla County. (Goeden, July 31). UTAH - Ranged 2-50
per 25 sweeps of alfalfa in Delta area of Millard County. (Wayland, Hurst).
KANSAS - Infested field in Meade County. Could be present over wide area in
southwestern and western sections. If current weather continues without drastic
change this could be severe threat to establishment of new stands of susceptible
alfalfa. (Gates, Aug. 5). VIRGINIA - Averaged 200 per 100 sweeps in 36 acres of
alfalfa in Halifax County. (Hendrick).
TOMATO HORNWORM (Manduca quinquemaculata) - WISCONSIN - Numerous on tomatoes in
some truck gardens in Sauk County. Treatments underway; larvae half grown. (Wis.
Ins. Sur.). VERMONT - Heavy in early tomato varieties in gardens. (Nielsen,
Aug. 4).
CORN, SORGHUM, SUGARCANE
EUROPEAN CORN BORER (Ostrinia nubilalis) - COLORADO - Larvae 4-6 per 100 row feet
of corn to date in Kiowa Valley, Weld County. (Johnson). KANSAS - Some light
infestations in Saline and Ottawa Counties. Some infestations in Republic County.
Early second-generation larvae in northeast area feeding at base of upper leaves
and beginning to tunnel into some stalks. Egg masses common in some fields. Moths
still heavy, over 500 in Brown County light trap. (Gates, Aug. 5). NEBRASKA -
First-generation larvae in Cuming County heavy in most of 20 fields. Infested
47-100 (averaged 77) percent of plants. Adults of summer generation laying eggs.
Moths averaged 6 per square yard in weedy and grassy borders of corn at Mead,
Saunders County. Egg masses of 10-25 eggs on less than 1 percent of plants in
adjacent corn. Adult emergence and egg laying should peak in east area next few
days. Substantial infestation of second-generation larvae expected if conditions
remain favorable. (Hill, Keith, July 31). First-brood activity currently light
in Hall County. Percent infestation ranged 0-34 (averaged 13.7) in 20 fields.
None economic. Moth emergence well underway. Emergence continues in east and
southeast with little egg laying. (Keith, Berogan). IOWA - Pupation in laboratory
100 percent with 70 percent of these emerged July 30 at Ankeny, Polk County.
Adults not occurring in light trap, but many kicked up from fencerows. Second-
brood egg masses easy to find. With average rainfall and cooler than average
temperature, larval survival will be high. (Iowa Ins. Inf., Aug. 3). MINNESOTA -
Second-generation moth flights in southwest, central, and east-central districts.
None in blacklight traps. Larvae ranged 25.3-36 per 100 plants in southwest and
west-central districts. Moth emergence 16 percent in southwest district and trace
in west-central district. (Minn. Pest Rpt.).
WISCONSIN - European corn borer up to 8 egg masses per 100 plants in pretassel
corn August 4 at Arlington, Columbia County. Cool weather restricted moth
activity. Over half fifth instars and over one-fourth pupae or new moths at
Columbus and Beaver Dam area as of August 4. Few third instars in Dane and Door
Counties. Pupae as far north and east as Kewaunee County. Pupation heavy in all
areas. Severe infestations expected in late sweet corn when warm weather
facilitates egg laying. (Wis. Ins. Sur.). MICHIGAN - Near perfect weather of
past few weeks encouraged second-brood emergence at Lenawee and Livingston
County stations July 22, ten days earlier than in 1969. Indications of heavier
than average population this season. Few eggs deposited July 30. Expect explosive
larval populations on sweet corn next 10-14 days. (Newman). INDIANA - Egg masses
in only 1 cornfield in southern districts, 6 per 25 plants on tassel-in-whorl corn
in southwest district. First-generation moth emergence nearly completed. Corn
nearly all tasseled and many silks browned. (Meyer, July 31). Adults currently
in central districts on grasses and corn. Only one second-generation larva in all
fields visited. (Meyer). ILLINOIS - Laying eggs on late corn, will continue for
7-14 days in southern area, 14-21 days in central area, 21-28 days in northern
area. Third generation likely in southern and south-central sections in late
- 978 -
August and early September. (Sur. Bull.). ALABAMA —- Full-grown European corn
borer larvae medium throughout 400-acre field of mature corn in Escambia County.
This is a new county record. Old larvae light but scattered in all corn examined
in Lauderdale, Colbert, Lawrence, Morgan, Cullman, Winston, Walker, Lamar, Marion,
and Fayette Counties. Occurred with H. zea (corn earworm), Spodoptera exigua
(fall armyworm), and Diatraea grandiosella (southwestern corn borer). (Martin et
al.). VIRGINIA - Moths numerous in light trap at Holland, Nansemond County, and
still moderate at Warsaw, Richmond County. Susceptible crops may need protection.
(Allen). DELAWARE - Egg masses and young second-generation larvae very abundant
on corn and sweet peppers in most areas. Adults still abundant in blacklight
traps statewide. (Burbutis et al.). NEW JERSEY - Second-generation moths increased
on sweet corn in most areas. (Ins.-Dis. Newsltr.). PENNSYLVANIA - Second-genera-
tion moths increased rapidly, 34 in Clinton County light trap night of August 3.
No egg masses August 4. (Gesell). NEW YORK - Moth catches remained heavy in black-
light trap at Geneva, Ontario County, through last week of July. Egg laying begun.
Treatment should be considered first week of August. First-generation moths
increased sharply in field and trap on sweet corn in Hudson Valley. Egg mass
hatched August 2 at Poughkeepsie, Dutchess County. (N.Y. Wkly. Rpt.).
FALL ARMYWORM (Spodoptera frugiperda) - ALABAMA - Scattered and light infestations
of older larvae in whorls of silking corn in Lauderdale, Colbert, Lawrence,
Morgan, Cullman, Winston, Walker, Lamar, Marion, and Fayette Counties. Pupation
10-15 percent. New generation expected in northern area next 10-20 days. Larvae
1-3 on 80-90 percent of plants in several fields of pretassel corn of 3-6 acres
each in Marion, Fayette, and Walker Counties. Nearly full-grown larvae present.

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-AUGUST TO MID-SEPTEMBER 1970
The Weather Bureau's 30-day outlook for mid-August to mid-September is for temper-
atures to average above seasonal normals over the western half of the Nation
except for near normal along the west coast. Elsewhere temperatures are expected
to average near normal except for below normal in the Southeast and the Ohio
Valley. Precipitation is expected to exceed normal over the northeast coast, the
Ohio Valley, the Southeast and the central and southern Plateau. Subnormal totals
are indicated for the Great Plains and California. Elsewhere near normal precipi-
tation is in prospect.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C. 20250. Price $5.00 a year.
WEATHER OF THE WEEK ENDING AUGUST 17
HIGHLIGHTS: Summer heat continued last week over most of the Nation. Severe flash
flooding occurred in western North Carolina. Drought intensified in many areas.
PRECIPITATION: Early in the week, a quasi-stationary front extended from the
southern Great Plains to the southern Atlantic coast. Heavy downpours, up to 10
inches or more, fell in the Appalachians north of the front. Mortimer, North
Carolina, received 11.10 inches of rain in 48 hours ending at 2 p.m., Monday,
August 10. Severe flooding occurred in the central and southern Appalachians.
Moderate to heavy thundershowers occurred along the gulf coast during the first
half of the week. Lighter, more scattered showers dotted the Rocky Mountains and
adjoining Great Plains. Weekend showers occurred over the northern and central
Great Plains, and along the gulf and Atlantic coasts. Wide areas from the Pacific
coast to the western edge of the northern and central Great Plains received no
rain last week. Many smaller scattered areas in the Central and East were missed
by the showers. Drought intensified in many areas.
Weather of the week continued on page 618.

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE
ARMYWORM (Pseudaletia unipuncta) - CALIFORNIA - Larvae heavy in soil in 200 acres
of corn at Madera, Madera County. (Cal. Coop. Rpt.).
CORN LEAF APHID (Rhapolosiphum maidis) - NORTH DAKOTA - Up to 150 per plant in
half-ripe and green barley in Pembina, Walsh, Grand Forks, and northern Traill
Counties. Up to 500 per head, along with Macrosiphum avenae (English grain aphid)
in wheat. Heaviest populations in bearded wheat. (Kaatz). ILLINOIS - R. maidis
decreased rapidly on field corn, apparently due to disease. Negative in many
fields and others show dying populations, Very few (less than one percent)
serious, or heavy. (Ill. Ins. Rpt.). MARYLAND - Populations below economic
levels statewide. (U. Md., Ent. Dept.). TENNESSEE - Heavy on sweet corn in
central area. (Batey, Jennings).
CORN EARWORM (Heliothis zea) - IDAHO - Infestations 90 percent on July 28, 10
percent on August 6, and 50 percent on August 10, in mature sweet corn plots near
Parma, Canyon County. Extensive damage by July 28 and most larvae had left ears.
First and second instars by August 10 and damage confined to ear tips. (Scott).
UTAH - Light in sweet corn in Fort Duchesne, Uintah County (Mathews), and Wayne
and Piute Counties (Chapman); moderate in Sevier County (Rickenbach). KANSAS -
Light trap catches show moths increasing. Larvae averaged 0.5 per ear in corn-
field in Brown County; about 1 per ear in 2 fields in Geary County; and 0.9 per
ear in field in Stafford County. (Bell). Averaged 1 per row foot in field in
Cherokee County. (Brooks). OKLAHOMA - Moderate in sorghum in Coal County and in
peanuts in Bryan County. Very light in sorghum heads in northeast area. (Okla.
Coop. Sur.). TEXAS - Larval damage heavy to corn foliage and ears in Culberson
County. (Neeb). ARKANSAS - Infesting soybeans, mainly in southeast area. Counts
vary but heavy in some cases. Heaviest (larvae 10 per row foot) in Ashley County.
Infestations earlier than usual. (Boyer). TENNESSEE - Damaged sweet corn in
central area. (Batey, Jennings). GEORGIA - Light to heavy on peanuts, and light
to moderate on soybeans in south area. (French, Aug. 7). MARYLAND - Ear infesta-
tions increasing slightly on Eastern Shore. (U. Md., Ent. Dept.).
GREENBUG (Schizaphis graminum) - COLORADO - Ranged 0-2,000 per sorghum plant in
Arkansas Valley. Heaviest in Otero and Crowley Counties; counts increasing in
Prowers and Bent Counties. (Burchett). ARIZONA - Averaged 50 per sorghum plant
at Kansas Settlement, Cochise County. (Ariz. Coop. Sur.). NEW MEXICO - Decreased
on grain sorghum in Luna and Hidalgo Counties. Some isolated fields will need
controls. (N.M. Coop. Rpt.). TEXAS - Declining in grain sorghum in High Plains.
Predators abundant and parasites increased. About 64 percent greenbug reduction
in grain sorghum at Lubbock July 23-30. Light on grain sorghum in Martin and
Midland Counties. Heavy in fields of young preboot grain sorghum in Midland
County. Light to moderate in El Paso, Reeves, and Pecos Counties. Light to moder-
ate on grain sorghum in Haskell and Knox Counties. (Rummel et al.). OKLAHOMA -
Very light to absent in most sorghum checked in northeast area. Ranged 100-150
per plant in occasional younger fields (just beginning to bloom), especially in
Ottawa County; numbers declining even in these fields. Parasites and predators
important in some fields, but hot, dry weather and plant maturity probably more
important in many fields. Greenbug heavy in sorghum in Coal County. (Okla. Coop.
Sur.). KANSAS - Remains heavy in some fields even though predators appear
abundant, while in many fields populations declining and attributed to predation
and parasitism. Based on population found July 30 in field of sorghum in Riley
County, parasitism accounted for about 35 percent of decrease. (Bell). NEBRASKA -
Greenbug continues to decline in east, southeast, south, and central districts.
Negative in many fields. (Leininger et al.). Damage to grain and forage sorghums
continues in north and northeast districts, parasitism still low (less than 10
percent). (Ehlers, Thomas), Heavily infested plantings of barley at Halsey, Thomas
County, nearly destroyed; parasitism increasing, currently near 50 percent.
(Sexson). SOUTH DAKOTA - S. graminum heavy on sorghum, controls required near
Redfield and Frankfort, Spink County; at Wagner, Charles Mix County; and near
Mitchell, Davison County. (Kantack, Aug. 7).
- 604 -
PICKLEWORM (Diaphania nitidalis) - MISSISSIPPI - Heavy on squash in Oktibbeha
County, (SantorymAug, 7k
POTATO LEAFHOPPER (Empoasca fabae) - WISCONSIN - Heaviest in podded lima bean
fields, as high as 3 per leaf in Rock and Walworth Counties. Counts of 1 per 3
leaves in fields still in blossom. Bud drop evident in some fields. (Wis. Ins.
Surepe.
SPOTTED ALFALFA APHID (Therioaphis maculata) - COLORADO - Up to 1,000 (average
150) per 100 sweeps of alfalfa in Pueblo, Otero, Bent, and Prowers Counties.
(Burchett). WYOMING - Averaged 3 per 10 sweeps in third-crop alfalfa field near
Hawk Springs, Goshen County. (Parshall). OKLAHOMA - Averaged 200 per 10 sweeps
of alfalfa in Tulsa County. (Okla. Coop. Sur.). KANSAS - Found in all fields
checked. Counts per sweep averaged 7.5 in one field in Reno County, 35 and 40
in 2 fields in Sedgwick County, 1 in one field in Sumner County, 1 in one field
in Kingman County, 4 in one field in Barber County, 30 and 70 in 2 fields in
Comanche County (Bell); ranged 250-350 per sweep in test plots of Buffalo
alfalfa, averaged 40 per sweep in Cody alfalfa plot and 5 per sweep in Kanza
alfalfa in Stafford County (Bell, Lundquist); and 2.5 and 5 per sweep in two
fields in Meade County (Bell). WISCONSIN - Increasing in alfalfa on sandy areas;
counts as high as 50 per sweep in some fields. (Wis. Ins. Sur.).
TOBACCO BUDWORM (Heliothis virescens) - GEORGIA - Light to moderate on soybeans
in south area. (French, Aug. 7).
CORN, SORGHUM, SUGARCANE
EUROPEAN CORN BORER (Ostrinia nubilalis) - KANSAS - Second generation heavy in

Weather of the week continued from page 602.
TEMPERATURE: Typical midsummer temperatures continued over most of the Nation
with little change. Cool weather persisted along the Pacific coast and the
mercury dropped to or near freezing in the northern and central Rocky Mountains
on 1 or 2 mornings. Big Piney, Wyoming, registered 27° Monday morning, August 10.
Early morning chill also occurred in the Northwest, and across the northern
border States to the Northeast. Afternoon temperatures across the South ranged
from hot in the southwestern deserts to quite warm in the Southeast. Daggett,
California, recorded 113° Monday afternoon. Afternoon readings in the 90! s were
common over the western Great Plains. Some Texas stations warmed to 100° or higher
on several days. East of the Mississippi, the highest temperatures remained
mostly in the 80's until the weekend when the Northeast and the Deep South warmed
to the 90's. Condord, New Hampshire, registered 96° Sunday afternoon. Higher
humidity and increased pollution accompanied the return of hot weather to the
East. Weekly mean temperatures were below normal from the central Great Plains
to the middle and southern Atlantic coast and above normal over most of the rest
of the Nation. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING AUGUST 24
HIGHLIGHTS: Typical summer heat continued over most of the Nation last week. The
East became more comfortable over the weekend. Little rain fell in the West. Most
of the eastern half of the Nation received 1 inch or more with heavy thunder-
showers dumping 2 to 8 inches in spots.
PRECIPITATION: At the beginning of the week, a storm center lay over the central
Great Plains. Quasi-stationary fronts stretched from this storm center northward
across the Red River of the North Valley and eastward to the middle Atlantic
coast. A tropical depression was centered about 40 miles off the Carolina coast.
Thunderstorms developed along the front that stretched eastward from Kansas to
Virginia. Some of the thunderstorms were accompanied by strong winds, heavy rain,
and hail. Up to 4.50 inches of rain fell in parts of northern Missouri in the 24-
hour period ending at 2 p.m., Tuesday. Kirksville, Missouri, registered 4.53 inches
during that period, and Slater, Iowa, 4.20 inches. Scattered thunderstorms also
soaked portions of the gulf coast. Midweek brought widely scattered thunderstorms
to many parts of the Nation. In general, they were spread from the central and
southern Rocky Mountains in the West to southern New England and northern Florida
in the East. Many stations from northern Missouri to Pennsylvania received over
an inch of rain in the 24-hour period ending at 8 a.m., Thursday. Several stations
in Pennsylvania received from 2 to more than 4 inches during that period. Some
totals in the Texarkana, Arkansas, area also exceeded 4 inches. The weekend
brought clear weather to much of the Central and East. Rains continued along the
gulf and Atlantic coasts. A few light rains also occurred in the Puget Sound area
in Washington...
TEMPERATURE: Seasonally warm weather occurred over the western half of the United
States early in the week. Miles City, Montana, registered 102° Monday afternoon
when temperatures reached 100° or higher in western South Dakota, from central
Kansas to central Texas, and in the Far Southwest. Burwell, Nebraska, recorded
102° and Russell, Kansas, 108° Tuesday afternoon. Hot humid weather continued over
the southeast quarter of the Nation, with temperatures in the 90's as far north as
Richmond, Virginia. At midweek, a high-pressure area centered in southern British
Columbia brought cooler temperatures to the northern Great Plains. The maximum
temperature at Minot, North Dakota, Wednesday afternoon was 71° in contrast to 95°
recorded Monday. Early morning readings in the northern and central Rocky
Mountains dropped to near freezing. Big Piney, Wyoming, registered 31° Thursday
morning. The Northeast continued seasonally mild with maximums mostly in the 80's.
The cool spell was short-lived, however. A quick warmup occurred in the northern
Great Plains shortly after midweek. Weather of the week continued on page 631.

WEATHER OF THE WEEK ENDING AUGUST 31
HIGHLIGHTS: Summer heat continued over the West and most of the Northern States.
Texas in the southeast averaged cooler than normal. Mid-America received no rain
or only light widely scattered showers. Generous rain fell along the gulf.
PRECIPITATION: Early last week, showers occurred along and in the moist air south
of a Slow moving front near the gulf and Atlantic coasts. Daily totals ranged to 1
or 2 inches and weekly totals were 3 to 4 inches or more. Lighter showers fell in
northern Great Plains, the Great Lakes region, and in New England. Light scattered
showers also fell in the northern and central Rocky Mountains. Heavy thundershowers
with hail occurred at Las Vegas, Nevada, on Wednesday and over 4 inches of rain
fell at Elko, Nevada, on Thursday. High pressure stretched along mid-America from
New Mexico to New York producing cloudless skies and no rain or only light
sprinkles from Arizona to Ohio and from Montana to Oklahoma. Only a few light
sprinkles fell in Kentucky, Virginia, and North Carolina except along the coast
of the latter States. Frontal activity produced weekend showers in the Northeast.
Scattered showers also continued along the gulf coast and widely scattered thunder-
showers occurred in the Great Basin and the Rocky Mountains.
TEMPERATURES: Hot weather was present throughout most of the West last week.
Temperatures averaged above normal except Slightly below along the coast as far
south as San Francisco. On most days, maximums reached the 90's as far north as
southern Washington and 100° or higher in the southwestern deserts. Thermal and
El Centro, California, registered 100° Saturday afternoon. Temperatures were
warmer than normal from the northern and central Great Plains, east across the
Great Lakes to Massachusetts. A large area from Texas to central North Carolina
averaged cooler than normal. The Atlantic coast areas and most of the Florida
Peninsula averaged slightly above normal. A large High brought comfortable
temperatures to much of the East last week. Early morning temperatures dropped
to the 40's and 50's in the Northeast. Nights were clear and days were sunny.
Afternoons were noticeably cooler and less humid than in the previous week.
Temperatures of mid-America climbed to 100° or more on 1 or 2 days at midweek,
reaching 103° at Bismarck, North Dakota, Chadron and North Platte, Nebraska, on
Wednesday. Cooler air moved into the northern Great Plains and Thursday tempera-
tures remained in the 70's over most of North Dakota with 90's in Nebraska. Early
morning fog occurred over much of the East early in the week. It was especially
widespread on Wednesday morning extending from Missouri to Maine, and from Lower
Michigan to northern Georgia. Weather of the week continued on page 650.
ROO i a
SPECIAL INSECTS OF REGIONAL SIGNIFICANCE
CORN EARWORM (Heliothis zea) - FLORIDA - Larvae 1 per 3 row feet of soybeans near
Gainesville, Alachua County. (Whitcomb et al.). ALABAMA - Larvae infesting soybean
pods in southern area; reported light to medium in many Geneva County fields.
Cotton, corn, and peanuts maturing in area; soybeans more attractive for egg
laying. Moth flights heavy. (Reynolds et al.). Larvae of H. zea, Spodoptera
frugiperda (fall armyworm), and Feltia subterranea (granulate cutworm) light to
medium and widespread throughout Covington County. Similar infestations throughout
9-county peanut area. (Pike et al.). SOUTH CAROLINA - Up to 25 larvae per row
foot on pods and blooms of early planted soybeans and on leaves and blooms of
younger plants in coastal Plain area. (Thomas). TENNESSEE - Increased moth
activity in soybeans expected. Corn and cotton becoming less attractive; soybeans
should be watched. (Gordon). VIRGINIA - Damaged 40 percent of ears in some Halifax
County fields. Larvae averaged 10 per 100 sweeps in 3 Charlotte County alfalfa
fields. (Hendrick). Widespread in peanut belt. Average per 100 sweeps and dominant
stage by county: Sussex 18, second instar; Southampton 80, third instar;
Nansemond 70, third instar; Isle of Wight 28, second instar. No larvae found in
peanuts in Prince George County. Surveys of soybeans in Sussex, Southampton,
Nansemond, Isle of Wight, and Prince George Counties indicate few larvae and less
than 1 percent of soybeans in any field cut. Reports from southern Piedomont area
indicate damage levels to soybeans similar. Based on blacklight catches, expect
Nansemond County and surrounding areas to experience much damage next few weeks.
Adult catches doubled at each light trap location, corn has dried in southern
Piedmont and Tidewater areas. This will force moths to peanuts and soybeans in
these areas. (Allen).

percent of plants; second brood averaged 1.7 per plant in about 10 fields
checked in Burt, Thurston, Dakota, Dixon, and Wayne Counties. Most second brood
in second to fourth instar and feeding mainly in ear tips. Many fields surveyed
suffering from drought, probably most important factor in high second-brood egg
and larval mortality. Populations heaviest in irrigated corn. (Hill et al.).
IOWA - Third generation of moths emerging at Ankeny, Polk County; appeared in
blacklight traps August 21. (Iowa Ins. Sur.). NORTH DAKOTA - Larvae ranged

FALL ARMYWORM (Spodoptera frugiperda) - SOUTH CAROLINA - One of worst economic
a Ga Tata ae a outbreaks in several years
Fall Armyworm Situation in South Carolina reported over large area. First
reported in Jasper County July
22. Within one month, infesta-
tions had spread to 22 counties;
damage was severe to lawns,
pastures, and golf courses.
Peak reached about mid-August.
Decline of spread and damage
attributed to control programs
by farmers and other property
owners. News media helpful in
alerting general public to
situation. Highly fertilized
areas more susceptable to
infestation than other areas.
Up to 90 percent defoliation
of Bermuda grass reported. No
attempt made to determine
total acreage infested. Very
little damage by Pseudaletia
unipuncta (armyworm) reported.

important species. Because of
rapid spread over such large
area, S. frugiperda moths
thought to have been blown in
Counties with severe damage by Hurricane Becky, as outbreak
reported. occurred shortly after storm.

pressures not so great as expected. Control satisfactory. Moth numbers did not
become heavy in northern counties, and egg numbers and small larvae remain light
in most fields. Treated 2,489 fields this period. (Barnes et al.). TENNESSEE -
Continues to cause much damage throughout west area. Most eggs being laid on
squares down in plant. Rank cotton remains attractive and should be watched.
(Locke). LOUISIANA - Moths abundant in cotton past 2 weeks; egg laying heavy in
many fields. Egg laying expected to be continuous as long as cotton growing and
squaring. Control good in most cases. (Tynes, Aug. 24). In Madison Parish,
damaged squares averaged 1.7 percent in 41 of 100 plots and fields. Damaged bolls
averaged 1.5 percent in 17 of 62 plots and fields. Moths increased; recovered

WEATHER BUREAU'S 30-DAY OUTLOOK
SEPTEMBER 1970
The Weather Bureau's 30-day outlook for September is for temperatures to average
below seasonal normals along the Pacific coast and also over the eastern third of
the Nation except for near to above normal in Florida, Above normal temperatures
are indicated for most of the intermountain region and the Great Plains. Else-
where near normal temperatures are in prospect, Precipitation is expected to
exceed normal over the Pacific Northwest, as well as eastern portions of the
Great Basin, and in the gulf coast region. Subnormal totals are indicated for the
upper and middle Mississippi Valley, the Ohio Valley, and the middle Atlantic
Coast States. In unspecified areas near normal precipitation is expected.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C, 20250. Price $5.00 a year.
WEATHER OF THE WEEK ENDING SEPTEMBER 7
HIGHLIGHTS: Rains in the Far Northwest dampened the forest and relieved the
dangerous forest fire situation, Soaking rains fell in spots in the Great Plains
and in some previously dry areas of the Southeast. Summer heat continued over much
of the Nation,
PRECIPITATION: As a high pressure area moved eastward from the northern Great
Plains early in the week, it was replaced by a low pressure area with a cold front
extending southward to Kansas and a warm front extending southeastward to South
Carolina, Scattered thunderstorms occurred over much of the Nation except the
Pacific Coast States and the Northeast. Heavy rains in southeastern Oklahoma and
eastern Texas at midweek caused considerable flooding along many streams in that
area. Sugarland, Texas, registered 3.84 inches in the 24-hour period ending at
7:00 a.m. Wednesday, and Tahlequah, Oklahoma, received 3.52 inches in the next
24-hour period. Shortly after midweek, light rains began to dampen the Northwest.
These helped the fire fighters in that area, At some locations these were the
first measurable rains since August 2. A number of violent thunderstorms occurred
in the central Great Plains. Winds gusting to 70 m.p.h. whipped Manhattan, Kansas,

the central Rocky Mountains Saturday evening. Damaging windstorms hit the central
Great Plains Sunday night. At Kearney, Nebraska, the gusts reached 81 m.p.h.
Weekly rainfall totals ranged widely within almost every State. California was
the main exception, receiving only widely scattered light sprinkles. Light
sprinkles occurred in parts of almost all other States with heavy showers falling
nearby. Rainfall was moderate to heavy in northern and western regions of the
important Corn Belt while the southern and eastern regions had generally light to
moderate precipitation.
TEMPERATURE: Canadian air cooled the Northeast early in the week. The interior
southeast continued hot and the Deep South warm and humid. Locations in the south-
western deserts warmed to 100° or more on several days. On Tuesday afternoon,
temperatures in the 90'S were common over a wide band from eastern Montana to
the eastern gulf and southern Atlantic coasts. Aberdeen, South Dakota, registered
102° Tuesday afternoon. Southerly breezes warmed the Northeast after midweek.
Rochester, New York, registered 44° Wednesday morning, but their lowest temper-
ature Friday morning was 73°. Most of Pennsylvania was 25° warmer Friday morning
than 2 days earlier. At other cool spots was Big Piney, Wyoming, where the
temperature dropped to freezing levels several mornings; 26° on Friday. Weekend
warming brought a return of 100° heat to spots in the central Great Plains. Huron,
South Dakota, registered 106° Sunday. Temperature and humidity increased in the
Northeast with 90° or warmer occurring at Washington, D.C., and Baltimore, Mary-
land, Temperatures averaged below normal over the Pacific States, the Great Basin,
and from Pennsylvania to Maine except along New England coast. Above normal
weekly averages occurred from the Continental Divide to the Atlantic Ocean except
the Northeast as noted above. Much of the northern Great Plains averaged 6° to
14° warmer than normal. (Summary Supplied by Environmental Data Service, ESSA).

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-SEPTEMBER TO MID-OCTOBER 1970
The Weather Bureau's 30-day outlook for mid-September to mid-October is for
temperatures to average above seasonal normals over the eastern third of the
Nation as well as in western portions of the central and southern Plateau region
and in Texas. Below normal temperatures are expected along the Pacific coast and
in the northern Plains. Elsewhere near normal temperatures are in prospect.
Precipitation is expected to exceed normal over the Mississippi Valley, the Great
Lakes, eastern portions of the Great Plains, and the north Pacific coast. Sub-
normal totals are indicated for portions of the middle and south Atlantic Coast
States, and also for California and the southern Plateau. In unspecified areas
near normal precipitation is expected.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the Weather Bureau. You can subscribe through the
Superintendent of Documents, Washington, D.C. 20250. Price $5.00 a year.
WEATHER OF THE WEEK ENDING SEPTEMBER 14
HIGHLIGHTS: The first winter storm hit the northern Rocky Mountains. Hurricane
Ella brought beneficial rains and no significant damage to Texas.
PRECIPITATION: Widespread sunshine covered most of the Nation last week. Pre-
cipitation occurred along a cold front as it advanced southeastward. On Monday,
these rains were scattered from Abilene, Texas, to Lower Michigan. Tuesday was
another fine day, except in the showers which prevailed from Kentucky to New
England. The northern and central Great Plains and eastward to Michigan and
Indiana received scattered showers Wednesday. Thursday's showers covered the
Northeast from West Virginia to New England. Light scattered rains continued along
the gulf. The first major winter storm swept into Montana on Friday. A low-pressure
area moved into the western part of the State from Alberta Thursday afternoon and
by Friday noon 3 inches of snow covered the ground at Cut Bank. Elsewhere in
Montana, the snowfall ranged from traces to several inches in the lower elevations
and there were reports of a foot or more in the southern mountains. Snow
accumulated to 14 inches on the highway in the Big Horn Mountains in Wyoming.
Weather of the week continued on page 680.

Weather of the week continued from page 668.
The snow hindered automobile travel and chains were required on many mountain
roads. Cold rain fell south and east of the snow area. By Sunday the rain area
extended from central Colorado to New England. Parts of the Corn Belt received
from 1.00 to 2.00 inches. Most of Texas received beneficial weekend showers as the
result of being caught between a cold front from the north and the peripheral
circulation of Hurricane Ella in southern Texas. The hurricane brought beneficial
rains but no important damage to Texas. California, Nevada, and parts of nearby
States received no rain or only light sprinkles last week.
TEMPERATURE: The approach of autumn brought the coolest weather of the season
to much of the Nation last week. Skies were mostly clear. Temperatures dropped
abruptly over the Great Plains as a cold front advanced southeastward. Aberdeen,
South Dakota, registered 98° Tuesday afternoon but the highest temperature at
Aberdeen Wednesday was 62°. Similarly, the maximum temperatures at Wichita,
Kansas, on Wednesday and Thursday were 102° and 76°, respectively. Southerly
winds on Friday brought the return of summer temperatures to the Great Plains,
86° at Aberdeen and 90° at Wichita. The Deep South and the Atlantic Coastal
States as far north as Maryland continued warm until the weekend approached.
Baltimore, Maryland, and Washington, D.C., registered 93° Thursday afternoon
before a cold front passed. Northerly breezes brought subfreezing temperatures
to the northern and central Rocky Mountains. Big Piney, Wyoming, registered 19°
Friday morning. Subfreezing weather also occurred in parts of the central Great
Plains. North Platte, Nebraska, recorded 30° and nearby Sidney, 29°, Friday
morning. Minimums in the 30's and 40's were common from Utah to Minnesota and
northern Wisconsin. Bryce Canyon, Utah, registered 28° Friday morning. Weekly
temperatures averaged above normal over most of California and nearby parts of
Nevada and Arizona and southeast of a line from southern New Mexico to northern
Ohio, and below normal over most of the rest of the Nation. A large area from
eastern Washington to western North Dakota and southward to the Nebraska
Panhandle averaged 9° to 14° cooler than normal. (Summary supplied by Environmental

WEATHER OF THE WEEK ENDING SEPTEMBER 21
HIGHLIGHTS: Light rain fell in the Northeast late in the week, Generous rain fell
in many parts in all eastern areas. The West continued cold, Summer weather per-
sisted in the East,
PRECIPITATION: Early in the week a storm moved northeast across the central Great
Plains to the Great Lakes. The combination of cool air north of this system
and the southerly flow of warm moist air replaced widespread rain and drizzle
from the north and central Great Plains to the north and middle Atlantic States.
A tropical depression developed Tuesday between the Florida Peninsula and the
Bahamas. It gained strength rapidly and moved across the Keys producing storm
gusting winds and locally heavy rains. Winds at Ft. Myers gusted to 58 m.p.h. and
over 4 inches of rain fell at Naples, Florida. Tropical storm Felice moved into
the Galveston, Texas, vicinity Tuesday afternoon, Winds at Galveston gusted to
55 m.p.h. and more than 6.25 inches of rain fell within a few hours, Felice moved
northward into north-central Texas and although decreased to 30 m.p.h., it con-
tinued to produce heavy rains with 3-6 inches at many locations and 5.80 inches
at Roanoke, Texas, in the 24-hour period ending Thursday morning. Thunderstorms
and shower activity continued Thursday night along a front that extended from
northeast Texas to the Great Lakes and in the warm moist gulf air that streamed
northward over the eastern half of the Nation, Heavy rains of 4-6 inches fell
Saturday in parts of northern Arkansas, Mostly cloudless skies dominated the
weather of the West until the weekend when light showers fell along the Washington
and Oregon coast,
TEMPERATURES: A low pressure area moved northeastward across the Great Plains
to the Great Lakes early in the week, Afternoon temperatures from Kansas to Lower
Michigan remained in the 40's and 50's Monday afternoon while the readings from
Texas to Ohio reached the 80's and 90's. The sharp contrast continued on Tuesday
when Concordia, Kansas, and Waterloo, Iowa, recorded 60° maximums and St. Louis,
Missouri, Springfield, Illinois, and Ft. Wayne, Indiana, registered in the 90's,
The heat spread eastward. On Wednesday, Baltimore, Maryland, registered 97°, a
record maximum for so late in the season, Subfreezing temperatures occurred in the
northern and central Rocky Mountains and much of the Great Basin early in the
week, Big Piny, Wyoming, registered 15° and Flagstaff, Arizona, 30° Tuesday
morning, The weekend brought the return of hot weather to mid-America. The mercury
at Imperial, Nebraska, reached 96° Sunday afternoon, Weekly temperatures were
below normal over the West, the North-Central, and the Northeast and above normal
elsewhere, Most of the Great Basin and northern Rocky Mountains averaged more than
6° colder than normal. (Summary supplied by Environmental Data Service, ESSA).

WEATHER OF THE WEEK ENDING SEPTEMBER 28
HIGHLIGHTS: The hottest weather of the year occurred in parts of the Northeast
before a cold front dropped temperatures 20° tc 30°. Heavy thunderstorms caused
flooding along some streams in the central Great Plains. Heavy snow fell in the
central Rocky Mountains. Brush fires burned uncontrollable in southern California.
PRECIPITATION: Showers and thunderstorms occurred early in the week along a
frontal system which extended from the upper Mississippi River Valley to Texas.
Heraldton, Oklahoma, received 6.00 inches and Blue Springs, Missouri, received
5.40 inches of rain in the 24-hour period ending Tuesday morning. Larger totals
fell in Oklahoma in the following 24-hour period, 7.93 inches at Stroud, and 6.38
inches at Norman. Tuesday afternoon, hail as large as baseballs fell about 10
miles south of Topeka, Kansas. These heavy rains caused overflowing of rivers
and flooding of lowlands. Heavy snow fell in the Wyoming and Colorado Rockies
shortly after midweek accumulating to 10 inches at Fraser, Colorado. Showers
continued over the central Great Plains and Ohio River Valley. The Northeast and
the gulf coast also received light rain Thursday evening and Friday morning.
Weekend showers and thunderstorms occurred along a sharp cold front as it
advanced southeastward across the Eastern States and the Deep South. The Far
Southwest continued dry. The unfortunate combination of no rain, low humidity,
and strong winds caused brush and forest fires to spread rapidly in southern
California and hindered their control.
TEMPERATURE: A large High centered off the northern Pacific coast brought
northerly winds, clear skies, and cool temperatures to most of the West. After-
noon temperatures were in the 50's and 60's on most days. Early morning readings
were generally in the 30's and 40's except in the Southwest where the 50's and
60's were common. Thursday morning, many stations in the northern Rocky Mountains
and parts of the Great Basin recorded temperatures in the 20's. Big Piney,
Wyoming, registered 14° on that day. Temperatures in the humid air that covered
the East and the Deep South ranged from warm to hot. Ninety-degree weather occurred
in central Ohio on Tuesday and Harrisbug, Pennsylvania, recorded 97° Thursday
afternoon. Numerous locations in the Northeast recorded higher temperatures than
had been previously recorded so late in the season. Trenton, New Jersey,
registered 90° or higher on 5 consecutive days; this is the first such occurrence
in late September in more than 100 years. The cold front that separated the
cold and warm airmasses reduced temperatures Slightly as it advanced southeast-
ward across mid-America. Weather of the week continued on page 706.

Weather of the week continued from page 694.
Another cold front, which pushed into the northern Rocky Mountains and northern
Great Plains shortly after midweek brought autumn weather to those areas.
Temperatures in Wyoming Thursday afternoon ranged from 39° at Lander to 58° at
Cheyenne. Thursday's maximums over the northern Great Plains ranged from the
50's near the international boundary to the 60's in northern Nebraska and Iowa.
As this front advanced southeastward, cool autumn weather replaced summer heat.
Much of the East was 20° or more cooler Sunday afternoon than on Saturday.
Temperatures averaged slightly above normal along the Pacific coast. Inland
portions of Washington, Oregon, and California and eastward to a line from
northwestern Wisconsin to southeastern Texas averaged cooler than normal. Much
of the Great Basin, the central Rocky Mountains, and the western edge of the
Great Plains averaged from 9° to 11° colder than normal. Most areas from the
northern and middle Atlantic coast averaged 6° to 15° warmer than normal.

WEATHER OF THE WEEK ENDING OCTOBER 5
HIGHLIGHTS: Last week was notable for an abundance of bright sunshine, pleasant
temperatures, and the absence of storms.
PRECIPITATION: For the Nation as a whole, the past week has been one of the
driest in many months. Except for a few light to moderate showers in the Atlantic
Coastal States early in the week, precipitation was mostly light and widely
scattered. A few flakes of wet snow mixed with rain fell in some higher elevations
in southern New York late Tuesday night and dense fog covered central and southern
Maine early Friday morning. Brief scattered showers and thunderstorms interrupted
the fine weather in southern Florida Friday and early Saturday. Rains also fell
late in the week from southern California to western Texas. Tucson, Arizona,
received over an inch of rain in one hour late Friday evening. The total rain
for the week at Tucson, 1.73 inches, is more than 2.5 times the September normal.
The rains in the Southwest helped bring the brush fires under control, The week-
end brought light snow flurries to northeastern Minnesota and Upper Michigan,
heavy thunderstorms, some with hail, to New England; and thundery weather to the
Southwest and to the lower Rio Grande Valley. A large area from Oregon and
California (except the extreme south) to the central and southern Appalachians and
from the Canadian border to the Gulf of Mexico received no rain during the week.
TEMPERATURE: Bright sunshine and unusually pleasant autumn temperatures prevailed
Over most of the Nation last week. Afternoon temperatures reached the 80's from
the northern Great Plains to Texas and eastward to the Florida Peninsula on
Wednesday afternoon. Cooler weather prevailed over the Northeast in sharp contrast
to that of the previous week. On Monday morning, September 28, subfreezing
temperatures occurred over northern Minnesota, western Wisconsin, and Upper
Michigan. Temperatures dropped below freezing several mornings in parts of the
Great Basin and the northern and central Rocky Mountains. Elsewhere minimums
ranged from the 40's in the North to the 50's and 60's in the South. In general,
temperatures averaged above normal from the Pacific Ocean to northern and central
Great Plains and below normal over the rest of the Nation. (Summary supplied by
Environmental Data Service, ESSA).

WEATHER OF THE WEEK ENDING OCTOBER 12
HIGHLIGHTS: An early winter storm spread subfreezing weather over the Rockies
and nearby areas. Snow fell as far south as the Texas Panhandle. Generous rain
fell ahead of the storm and along the frontal area.
PRECIPITATION: Only meager precipitation fell early in the week. This included
Tight rain in Washington and northwestern Oregon and scattered showers in
southern New Mexico, southwestern Texas, and southern Florida. A large storm
developed Tuesday over the northern Great Plains. Warm moist air streamed north-
ward ahead of the storm setting off showers and local thunderstorms from the
upper Mississippi River Valley to eastern Texas. Snow fell in the cold arctic
air behind the storm, driven by strong northerly winds. By 2 p.m. Wednesday the
snow at Wheatland, Wyoming, had accumulated to 12 inches. Three to 7 inches
covered other parts of Wyoming. By evening, snow up to 12 inches covered the
Colorado Rockies and 5- to 7-inch depths were common over Wyoming and western
Nebraska. The snow pushed southward and eastward. By midnight Wednesday, moderate
snow was falling as far south as Clovis, New Mexico, and Dalhart, Texas.
Thursday evening and Friday morning, snow reached measurable depths at Grand
Island and Lincoln, Nebraska. This was the first time either of those localities
has seen more than a few flakes of Snow so early in the season. About midweek a
tropical depression produced torrential rains in the Caribbean and caused
flooding in parts of some of the islands. At dawn Friday, 16 rivers in Puerto
Rico overflowed as the result of 25-33 inches of rain in 5 consecutive days. The
flooding waters destroyed or damaged hundreds of houses and numerous bridges.
Early Thursday morning, heavy local downpours of from over 5 inches to almost 12
inches in 6 hours caused flash floods in Oklahoma. As the weekend approached,
light rains continued in the Pacific Northwest, snow fell from western Minnesota
to eastern Kansas, bright sunny weather prevailed from California to western
Texas and widespread thundershowers covered the large area from the Great Lakes
to the Gulf of Mexico. These showers were especially heavy in southeastern Texas
and southwestern LouiSiana. Beaumont, Texas, received 11.50 inches of rain
Sunday. Much of the Southwest received no rain or only widely scattered sprinkles.
Weather of the week continued on page 724.

1971 necessary to prevent starvation. Very little brood present October 7. Many
colonies of mostly old bees will not survive winter. Increase of American
foulbrood expected. (Little).

FEDERAL AND STATE PLANT PROTECTION PROGRAMS
EUROPEAN CRANE FLY (Tipula paludosa) - WASHINGTON - Many males in light trap at
Mt. Vernon, Skagit County, September 1-14. (Eide).
MEXICAN FRUIT FLY (Anastrepha ludens) - CALIFORNIA - About 15,000 sterile flies
released each week at San Ysidro, San Diego County. Release began September 23
after recovery of 13 native flies since July 7. Will attempt to coincide weekly
releases with those on Mexico side of border. (PPD).
GRASSHOPPERS - ARIZONA - Extensive feeding injury in 3 older citrus groves in
Salt River Valley, Maricopa County. (Ariz. Coop. Sur.).
ORIENTAL FRUIT FLY (Dacus dorsalis) - CALIFORNIA - Single fly taken October 12 in
Garden Grove, Orange County. This catch is 3 miles east of location where third
fly was taken in Garden Grove September 18. Since September 4, a total of 7 flies
has been trapped in adjacent Orange and Los Angeles Counties. (PPD).
PINK BOLLWORM (Pectinophora gossypiella) - CALIFORNIA - Two fourth instars
collected from separate cotton bolls in 40-acre field at Bakersfield, Kern County,
October 5. (Cal. Coop. Rpt.). This is same field where first native moths trapped
this year. State personnel to apply controls 2 or 3 times to this field and those
within l-mile radius. Cotton will be harvested about November 1. All trash from
this and surrounding fields will be processed to recover larvae. Released
5,716,545 sterile moths October 2-8 at Bakersfield; total to date 64,889,185.
ARIZONA - Released 67,500 sterile moths at Redington, Pima County, during same
period; total to date 1,484,800. First moths sterilized at reduced dosage of 15
kilorad released at Redington. Boll infestation in 500-boll sample taken at this
location was 6.6 percent; infestation 19 percent previous week. Four native and
six sterile moths trapped for respective totals of 43 and 241. (PPD). Late-
planted cotton, formerly 15-20 percent infested, now 100 percent infested at
Safford, Graham County. (Ariz. Coop. Sur.). NEW MEXICO - Infested up to 32 percent
of bolls in 1-2 fields in southern Eddy County and up to 50 percent in 2 fields in
southern Dona Ana County. (N.M. Coop. Rpt.).
Weather of the week continued from page 718.
TEMPERATURE: High pressure, sunny skies, and pleasant temperatures prevailed
over most of the Nation early in the week. Late Monday a storm strengthened
over the northern Great Plains. Warm moist air streamed northward ahead of the
storm. Cold arctic air plunged southward behind the storm. Freezing temperatures
occurred in spots in the central Appalachians Tuesday morning, October 5, when
Elkins, West Virginia, registered 31°. Subfrezzing temperatures spread through
the Rocky Mountains, the Grat Basin, and the western portions of the Great Plains.
Sharp temperature drops occurred as the cold air replaced warmer weather.
Billings, Montana, registered 81° Tuesday afternoon but only 39° on Wednesday.
The maximum temperatures at Miles City, Montana, on Wednesday and Thursday were
86° and 39°, respectively. More than a dozen States saw subfreezing weather
Thursday morning with minimums ranging from a few degrees below zero in parts
of Wyoming to 26° at Flagstaff, Arizona, and 27° at Grants, New Mexico. Laramie,
Wyoming, registered 7° below zero. Strong winds reaching 50 m.p.h., raised clouds
of dust in parts of Arizona and New Mexico. In general, the western and central
portions of the Nation cooled during the week, becoming especially cold on
Saturday when maximums over the northern and central Rocky Mountains and northern
and central Great Plains were mostly in the 30's and 40's. Most of this area
averaged 6-16° below normal and 15-20° colder than the previous week. The East
warmed sharply. Portions of the Northeast averaged 3-9° above normal and 5-10°
warmer than the previous week. (Summary supplied by Environmental Data Service,
ESSA.)

WEATHER OF THE WEEK ENDING OCTOBER 19
HIGHLIGHTS: Most of the Nation enjoyed sunny, cool autumn weather. Snow fell in
the central Rockies, in the Syracuse, New York, vicinity, and in northern Maine.
Heavy thundershowers and a few tornadoes occurred in Mississippi.
PRECIPITATION: Early in the week, precipitation continued along a front that
stretched from the lower Great Lakes to southwestern Louisiana. Numerous
locations in Louisiana and Mississippi received more than 1.0 inch in the 6-hour
period ending at 8 a.m., Monday, October 5. Lake Charles, Louisiana, received
4.8 inches in the 24-hour period ending at that time. A few tornadoes occurred
Tuesday morning in Louisiana and Mississippi, and many more in the forenoon in
Mississippi. Damages were mostly light. A wide band of rainy weather spotted by
thunderstorms preceded the front as it moved eastward toward the Atlantic Ocean.
Snow flurries fell in southern Wyoming, northern Colorado, and western Nebraska,
and a mixture of rain and snow fell from the northern and central Great Plains to
the Ohio River Valley and the lower Great Lakes Wednesday. In the afternoon and
evening, snow continued in southeastern Colorado and spread to northern New
Mexico. Albuquerque, New Mexico, measured 5 inches late Thursday. Showers con-
tinued ahead of the cold front from New England to the southern Atlantic States
on Thursday. Light rain was still falling along the coast on Friday. Oklahoma
and northern Texas received light, scattered weekend showers. The weekend also
brought 5-10 inches of wet snow to some communities in the Syracuse, New York,
area; 5 inches at Pompey and 10 inches at Marcellus, early Saturday morning.
Several inches of snow fell in northern Maine Sunday forenoon. Elsewhere the
weekend was mostly sunny due to the large high-pressure area that extended from
the Great Basin to the Atlantic Ocean and from Canada to Mexico.
TEMPERATURE: Sunny, mild weather prevailed over most of the Nation early in the
week. Afternoon temperatures were mostly in the 40's and 50's in the North and
the 70's and 80's in the South. The main exception to the fine weather was a
cloudy, rainy area from Arkansas to the Great Lakes along and ahead of a front
that separated two high-pressure areas. By Wednesday much cooler weather was
spilling across the Nation's midsection. The front moved eastward and by
Thursday high pressure dominated the weather from the Rocky Mountains to the
Appalachians. This was accompanied by sunny, cool, dry weather over most of the
Nation. North Platte, Nebraska, registered 19° Thursday morning. In contrast,
Macon, Georgia, still in the warm air ahead of the front, registered 91° By
Saturday the cold front had moved off the coast, and Sunday morning subfreezing
temperatures were common in the central Appalachians and Piedmont. Columbia,
South Carolina, registered 31° Sunday morning. The Atlantic Coast States
averaged near or slightly warmer than normal in spite of the cool weekend. Else-
where over the Nation, weekly mean temperatures were mostly below normal. A

WEATHER OF THE WEEK ENDING OCTOBER 26
HIGHLIGHTS: The rainy season is getting underway in the Pacific Northwest.
Generous rains fell in the Deep South early in the week and over the weekend. Mid-
week rains soaked the central and southern Great Plains. Light autumn weather
prevailed over the northern Great Plains.
PRECIPITATION: Skies were mostly clear as the week began. The main exception was
an area from the central Great Plains to the Gulf of Mexico where clouds produced
intermittent rain. Heavy amounts fell at a few places, 5.89 inches at Meridian,
Mississippi, in the 24-hour period ending at 8:00 p.m. Monday. The rains spread
eastward over the Deep South with numerous localities from Alabama to Georgia
receiving 24-hour totals ranging from 2 to more than 3 inches. Light rains also
fell in the Pacific Northwest as the week progressed. A series of fronts brought
a changeable weather pattern, clouds and snow alternating with sunny skies. As
one system moved to the Atlantic late Thursday another produced thunderstorms,
some with winds and hail over the central Great Plains, and a third system, the
most intense, dotted the Washington coast with winds up to 70 m.p.h., soaked
coastal areas with heavy rains, and covered the mountains with snow. Snow depth
accumulated to over 30 inches in some of the higher mountains of Idaho and Wash-
ington. A large area from the southwestern deserts to the western portions of
Kansas, Oklahoma, and Texas received no rain or only widely scattered light
sprinkles during the entire week. To the other extreme, spots in the Deep South
received over 4 inches. Key West, Florida, received 6.88 inches and 4 to more than
6 inches fell along the northern Pacific coast where the rainy season is getting
underway.
TEMPERATURES: High pressure continued to bring clear skies and moderate tempera-—
tures to most of the Nation at the beginning of the week. As the week progressed,
a series of cold fronts brought clouds and in general, smaller daily temperature
ranges. The temperature range at Elkins, West Virginia, Monday was 45° from 22°
in the morning to 67° in the afternoon. On Thursday the range was 8° from 52
in the morning to 60° in the afternoon. Subfreezing minimum temperatures occurred
on 1 or 2 mornings over parts of the northern Great Plains and on several mornings
over the central Rocky Mountains. Alamosa, Colorado, registered 22° Monday morning.
A warmer trend occurred over the central and southern Great Plains during the
week. Maximums in Oklahoma increased from the 60's on Monday to the 70's on
Tuesday and the 80's on Wednesday and Thursday and dropped to the 60's and 70's
on Saturday. Weather of the week continued on page 751.

WHITEFLIES infested 88 percent of groves; economic in 29 percent. Increased and
near record high October level of year ago. Decrease to moderate level expected
in November. Highest districts north and east. (W.A. Simanton (Citrus Expt. Sta.,
Lake Alfred)).
Quarterly Citrus Insect and Mite Outlook in Florida - October through December -
This outlook iS based on the asSumption that weather beyond the period of the
current U.S. Weather Bureau 30-day Outlook will be normal. Therefore, the fore-
casts given below cannot be viewed with the same degree of confidence as those
in the "Insect and Disease Summary'' usually released twice each month by this
station.
CITRUS RUST MITE will continue in high range until December. Increase expected
until mid-November followed by gradual decrease. Heavy infestations will occur
in about 20 percent of groves. CITRUS RED MITE and TEXAS CITRUS MITE will increase
steadily until year's end. Statewide population not expected to exceed normal low
to moderate level. Heavy infestations of either species may build up rapidly in
young groves. WHITEFLIES will increase in October, then decrease in November and
December. Expected to be above average and in high range in most districts.
GLOVER SCALE, PURPLE SCALE, YELLOW SCALE, and BLACK SCALE will gradually increase
through December but not expected to become troublesome during rest of year. An
ARMORED SCALE (Unaspis citri) will attain higher statewide level than in any
=e Oli
prior month due to intensification within groves and probable spread to previously
uninfested groves by picking crews and equipment. MEALYBUGS will continue to
decline to very low level. (W.A. Simanton).

On the Scientific Name of the Brown-Banded Cockroach, Supella
longipalpa (Fabricius) (Dictyoptera, Blattaria, Blattellidae)
Ashley B. Gurney 1/
Ten years ago, my friend Dr. Karlis Princis of Lund, Sweden, reported finding
that the above Fabrician name applies to the species then almost universally
known as Supella supellectilium (Serville) (Princis, 1960, p. 193). Personally, I
wish that conservation of sSupellectilium (Serville, 1838) had been requested from
the International Commission on Zoological Nomenclature. However, that was not
done, and during the past 10 years there has been sufficient use of S. longipalpa
(F,) 1798 to make any current effort to conserve supellectilium unwarranted. For
this reason, I have recommended that S. longipalpa be adopted in the forthcoming
edition of the Common Name List.
That longipalpa has priority over supellectilium is clear. Fabricius (1798, p.
185) described Blatta longipalpa from “India orientali Dom. Daldorff," i.e.,
eastern India, Mr. Daldorff (collector). Princis (1960) examined the type specimen,
a male, which also was recorded by Zimsen (1964, p. 614) as part of the Fabrician
Collection in Copenhagen, Denmark, it having been obtained from a collection of
Fabrician specimens in Kiel, Germany. Earlier, Shelford (1908, p. 468) had reported
the unavailability of the type, but he was unaware of its presence at that time
in Kiel. Judging from the travels of D.K. (or I.K.) Daldorff, as reported by
Henriksen (1923, p. 121) and Zimsen (1964, p. 12), the type of longipalpa probably
was collected in Tranquebar, which is in the State of Madras, on the eastern side
of the Indian peninsula. It is not known how early longipalpa was established
there, but Annandale (1907) said that it was "found throughout the Peninsular
region." Daldorff arrived in Tranquebar in early 1791 and was there or nearby
much of the time for 7 years or longer. Princis (1963, p. 249) mistakenly listed
the type locality of longipalpa as "Ile-de-France (=Mauritius) ,"" probably by
inadvertence while thinking in terms of supellectilium.
Serville (1838, p. 114) described Blatta supellectilium from "Ile de France." Now
known as Mauritius, located in the Indian Ocean about 500 miles east of Madagascar,
the island was called Ile de France by the French who colonized it during 1715-
1810, but since then it has been under British administration. Prior to the
French, the island was colonized by the Dutch, so there was a long history of
international shipping to and from the island. Serville said that supellectilium
was reported to be very common on Mauritius only in houses, occurring always
amidst furniture, especially in the drawers of chests, and he referred to it
(in French, "Blatte des meubles") as the furniture cockroach, a common name which
has persisted in some countries. The species name is from the Latin noun
"supellex," meaning household goods, furniture, utensils, and the like. The logi-
cal depository for the type specimen of supellectilium is the Paris Museum, but
Rehn (1947, p. 65) said that Dr. L. Chopard wrote him that the type had been lost.
Even in the absence of a type specimen, however, it appears that what usually
has been called supellectilium is indeed the species agreeing in description and
behavior with Serville’s Species, and with longipalpa, so there is no reason to
question the synonymy reported by Princis (1960). Related species of Supella have
been reviewed by Rehn (1947, pp. 60-92) and Princis (1963, pp. 248-252; 1969).
Evidence from related species and early records of longipalpa (usually under the
name supellectilium) indicate clearly that the brown-banded cockroach is native to
Africa, whence it Spread by association with man. Rehn (1945, 1947, pp. 68-70)
has discussed its occurrence in Africa and the history of its growing distribu-
tion.
Prior to 1960 there was very little use of the name longipalpa in entomological
literature, consisting of only about a half-dozen catalogue-style listings.
Beginning in 1967, there have been at least 5 widely circulated papers: on
17 Systemic Entomology Laboratory, ARS, USDA, U.S, National Museum, Washington,
DCE
- 752 -
- 753 -
cockroach biology by Dr. Louis M. Roth, including an important review paper
(Roth, 1970) in which the name longipalpa is used. Also, usage of longipalpa has
begun in Canada, and a very strong precedent for accepting longipalpa has been
its use by Princis (1969) in a carefully prepared world catalogue of the cock-
roach fauna. Usage of the name supellectilium grew rapidly after 1900, as the
species became more generally established and came to the attention of entomolo-
gists in numerous countries, so that the list of references under that name by
Princis (1969) occupies the equivalent of about 4 full pages in the Junk Catalo-
gue format. In spite of this wide contrast in usage, the name longipalpa should
now be adopted because of priority and the extent to which longipalpa is already
being accepted in substantial literature.
Family and ordinal placement - In the most generally used or "modern" classifi-
cation, living (not fossil) cockroaches are placed in 5 families, in contrast to
the traditional recognition of only one family (Blattidae) or of numerous fami-
lies, as has been done by several entomologists. Accordingly, Supella now is
placed in the family Blattellidae, following the conclusions of McKittrick
(1964) , which are Supported in large part by current fundamental studies such as
those of Roth (1970).
Similarly, current“usage favors removal of cockroaches from the Orthoptera in a
restricted modern sense and placing them as a suborder, the Blattaria, in the
order Dictyoptera. The subordinal names Blattaria and Blattariae both were used
for suprageneric categories earlier than Blattoidea and several other more recent
names. Blattaria was introduced by Burmeister (1829, p. 32) and is preferable
to Blattariae, established by Latreille (1810, p. 244), because the ae ending
is the standard one for insect families and subfamilies, thus is misleading if
used in a subordinal sense. Blattaria is now used in the revised Imms textbook
(1960 printing) and many other standard works.
The modern classification of this species, therefore, now stands as follows:
Order: Dictyoptera
Suborder: Blattaria
Family: Blattellidae
Genus: Supella
Species: longipalpa (F,)

NATIONAL WEATHER SERVICE'S 30-DAY OUTLOOK
NOVEMBER 1970
The National Weather Service's 30-day outlook for November is for temperatures to
average above seasonal normals in northern border States extending from the
Rockies to the Appalachians and also in California and portions of the central
and southern Plateau. Below normal averages are indicated for the South and the
southern Plains. Elsewhere near normal temperatures are in prospect. Precipitation
is expected to exceed normal along the central and north Pacific coast and from
the Mississippi Valley to the east coast except for near to below normal in the
Northeast. Subnormal precipitation is indicated for the Southwest. In unspecified
areas near normal amounts are expected.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the National Weather Service. You can subscribe through
the Superintendent of Documents, Washington, D.C. 20250. Price $5.00 a year.
WEATHER OF THE WEEK ENDING NOVEMBER 2
HIGHLIGHTS: Flood producing rains fell in southwest Texas and nearby parts of
Louisiana. The West continued relatively cool, the East mild.
PRECIPITATION: A front stretched across the middle of the Nation from Wisconsin
to Texas early in the week. A blocking high pressure area lay east of the front.
By midweek, the southern end of the front had drifted only to Louisiana. A snow-
storm moved out of the central Rocky Mountains to the central Great Plains.
Several inches of snow fell Monday in parts of Nebraska and Kansas; 7 inches at
Hays Center in the latter State. Severe thunderstorms, heavy showers, several
funnel clouds, and a few tornadoes occurred in the warm moist air east of the
front. Five to eight inches of rain fell in some localities in Arkansas on
Tuesday forenoon, 8.20 inches at Jessieville, 6.12 inches at Little Fork.
Deweyville, Texas, received 17.53 inches in the 24-hour period ending at 7:00
p.m. Central Standard Time and the rain was still falling at that time. Soaking
rains occurred Tuesday night over a wide area from the Great Lakes to the Gulf
of Mexico. As the far end approached, the southern part of the front swung east
to Georgia. It brought rainy weather over a wide band from New York to Georgia.
A low, centered over eastern South Dakota, produced snow flurries over the
northern Great Plains and rain showers over the central Great Plains. A high in
the Far West was accompanied by fair weather. Weather continued on page 762.

WEATHER OF THE WEEK ENDING NOVEMBER 16
HIGHLIGHTS: Temperatures averaged above normal in the Northwest and from the
Great Lakes region to the Northeast and below normal over the South from Arizona
to Alabama. General rain fell in most of the Deep South.
PRECIPITATION: Early in the week a cold front extended from a storm centered in
southern Minnesota to the Gulf of Mexico, Lines of showers and ‘thunderstorms
occurred in advance of the front. A few light snow flurries were noted in Minne-
sota to the front and across the country from west to east during the week,
causing alternating periods of fair and inclement weather. Snow whitened the
northern Great Plains. Rainy, windy weather prevailed in the Far Northwest with
snow in the mountains. As the weekend approached, snow fell in the Rocky Mountains
and in the Great Plains from the Dakotas to Oklahoma. Rain flooded lowlands along
some streams in south-central Pennsylvania, northeastern West Virginia, and
extreme northern Virginia late Thursday night. The weekend weather was mostly
gloomy and depressing. The rains continued in the Pacific Northwest and generally
inclement weather prevailed from the Mississippi River to the Atlantic Ocean
TEMPERATURES: A cooling trend held afternoon temperatures over the northern Great
Plains to near freezing; elsewhere there was little temperature change during the
week. In both the West and the East maximums ranged from the 50's near the
Canadian border to the 70's across the South. Freezing temperatures occurred on
several mornings over the Great Basin, the Rocky Mountains, and the northern and
central Great Plains. Douglas, Arizona, registered 28° on November 9, Subfreezing
weather occurred on 1 or 2 mornings early in the week in the central Applachians.
Weekly mean temperatures were generally slightly above normal in the West and from
the Great Lakes region to the Northeast and much below normal in most of the Deep
South. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING NOVEMBER 23
HIGHLIGHTS: Subfreezing temperatures occurred over much of the Nation early in
the week. A weekend storm brought subzero temperatures to the northern Rockies
and the northern Great Plains, and strong winds accompanied by heavy snow and
freezing rain to those areas eastward to the Great Lakes.
PRECIPITATION: Light rain continued in the Far Northwest. Elsewhere precipitation
was mostly light and widely scattered early in the week. Snow flurries occurred
in the northern border States. High pressure dominated the West and the East and
a cold front lay between. The front brought little precipitation, however, and
fair weather prevailed until about midweek. By Thursday, Snow was occurring over
a wide belt from the northern Rocky Mountains to the Great Lakes and cold rain
fell from the central Great Plains to the middle Mississippi River Valley. Snow
also fell in northern Maine and at higher elevations in the northern Applachians.
A storm developed in the central Great Plains. The storm center moved from central
Oklahoma to Illinois on Thursday afternoon and evening setting off severe storms.
Tornadoes associated with the storm caused considerable damage and a few injuries
in Arkansas. Precipitation became widespread over the eastern half of the Nation.
Snow and fog reduced visibilities in the northern Great Plains. Late Thursday
evening, artic air streamed southward at the western edge of the northern Great
Plains causing intermittent snow accompanied by strong winds. This storm blanketed
the eastern slopes of the northern Rocky Mountains and the northern Great Plains
with 4-10 inches of snow. By late Sunday night, severe wintry weather and high
winds with heavy snow or freezing rain covered a large area from the Great Lakes
region to the southern Great Plains.
TEMPERATURES: A cooling trend early in the week brought subfreezing temperatures
over most of the Nation. The middle Atlantic coast escaped the freezing tempera-—
tures, Savannah, Georgia, and Jacksonville, Florida, registered 28° and 29°
respectively, however. Temperatures in the southern part of the Florida Peninsula
dropped to the 40's, 41° at Fort Meyes and 46° at Miami. Southerly winds warmed
the Great Plains. Grand Island and Lincoln, Nebraska, registered 62° Tuesday
afternoon. As the weekend approached, cold temperatures and strong winds moved
down across the western edge of the northern Great Plains. The temperatures at
Cut Bank, Montana, dropped 17° in 30 minutes Thursday afternoon, and by Friday
morning had fallen to 4 from 43° the previous afternoon. The weekend brought
cold weather to much of the Nation. Subzero temperatures occurred in the
northern Rockies Monday morning and subfreezing weather as far east as the
northern Applachians, and as far south as Little Rock, Arkansas, and Memphis,
Tennessee. Weekly mean temperatures averaged below normal from Montana and North
Dakota to western Colorado, and from the Ohio River Valley to the Gulf of
Mexico and the middle and southern Atlantic coast. The Great Basin and the wide
band from Minnesota to Michigan southwestward to Arizona, New Mexico, and Texas,
averaged warmer than normal. (Summary supplied by Environmental Data Service,

WEATHER OF THE WEEK ENDING NOVEMBER 30
HIGHLIGHT: Warming trends occurred over most of the South. Temperatures were
quite erratic over the northern border States and averaged below normal. Heavy
rains fell along the Pacific coast. Light to moderate precipitation occurred over
the Northern States. Little or none over the South.
PRECIPITATION: Only sparse precipitation occurred over much of Nation last week.
The area with little or no precipitation extended from Arizona to the Atlantic
coast. Cold air blowing across the relatively warm waters of the Great Lakes
became loaded with moisture and dumped heavy snow on the south and east shores
of the Lakes especially in western portions of Pennsylvania and New York where
snow depths ranged up to about 12 inches. Some roads became completely blocked.
A new surge of arctic air swept down into the northern and central Great Plains
at midweek. Winds at Minot, North Dakota, gusted to 58 m.p.h. Wednesday. Heavy
snow fell at some localities in the northern border States. As the weekend
approached, a Pacific storm centered off the Washington coast was bringing rain
along the coast as far south as northern California and snow in the coastal
ranges and Cascades and eastward to the western edge of the northern Great Plains.
At elevations of 3,000 to 5,000 feet in the Cascades snow sepths now range from
30 to 50 inches. Another low brought heavy weekend rains to southern California
and heavy snow at Mount Shasta where 35 inches fell in 36 hours Friday and
Saturday.
TEMPERATURE: The week began with a cold wave pushing southward over central and
eastern portions of the United States. On Monday morning temperatures in Iowa
had tumbled close to the zero mark and by Wednesday morning many Floridians
shivered in subfreezing weather with Tallahassee recording 13°. A warming trend
occurred over the West. The mercury at Chardon, Nebraska, climbed from 7 Monday
morning to 69° Tuesday afternoon and the minimum temperature at Salt Lake City,
Utah, Wednesday morning was 57°. Denver, Colorado, registered 76° Wednesday
afternoon, the warmest in that city so late in autumn. Temperatures were eratic
over the northern Great Plains, climbing from much below zero in northern Montana
Monday morning to 40° and 50° Tuesday afternoon, and tumbling back to near zero
Wednesday morning as a new cold wave moved in from Canada. Imperial, Nebraska,
registered 77° Wednesday afternoon before falling back to 27° Thursday and
remaining below freezing all day Thursday. A warming trend pushed afternoon
temperatures to 60° over Nebraska and Kansas on Saturday. Oklahoma and Texas
warmed to 70° and 80°. North Dakota remained below freezing. Weekly mean tempera-
tures were 6° to 12° below normal along the Canadian border from northeastern
Washington to the Great Lakes and 6° to 12° above normal from the Great Basin to
the Nebraska Panhandle, (Summary supplied by Environmental Data Service, ESSA.)

COOPERATIVE ECONOMIC INSECT REPORT
ESTIMATED LOSSES AND PRODUCTION COST ATTRIBUTED TO
INSECTS AND RELATED ARTHROPODS - 1969
Introduction
Prior to 1966, insect loss estimates were published in the Cooperative Economic
Insect Report as individual reports. An attempt has been made for the fifth year
to condense loss estimates from various States into a single report. This gives a
more meaningful and better overall picture of the crop losses. The data have been
compiled from the crop loss estimates submitted from 19 States. The entomologists
submitting the 1969 estimates are listed below.

NATIONAL WEATHER SERVICE'S 30-DAY OUTLOOK
DECEMBER 1970
The National Weather Service's 30-day outlook for December is for temperatures to
average below seasonal normals over the Pacific coast, the northern and central
intermountain region,and the northern Plains. Above normal averages are indicated
for the eastern third of the Nation as well as for the southern Plains. Elsewhere
near normal temperatures are in prospect. Precipitation is expected to exceed
normal over the Midwest, the northern Plains, northern and central portions of
the intermountain region, and along the Pacific coast. Subnormal totals are
indicated for the southern Plains while near normal precipitation is expected
in unspecified areas.
Weather forecast given here is based on the official 30-day "Resume and Outlook"
published twice a month by the National Weather Service. You can subscribe
through the Superintendent of Documents, Washington, D.C. 20250. Price $5.00 a
year.
WEATHER OF THE WEEK ENDING DECEMBER 7
HIGHLIGHTS: Unusually mild except very cold from northern Montana to northern
Minnesota. Wet and windy along the Pacific coast.
PRECIPITATION: Early in the week a cold front, accompanied by strong gusty winds
and blowing dust and sand, moved across mid-America. Rain and fog occurred in the
North and showers in the East. A Pacific storm produced rain in the lower valley
and hills and snow in the Cascades and northern Sierras. The mid-America storm
pushed eastward and by Thursday night had dumped 6 to 12 inches of snow from
northeastern Minnesota to Upper Michigan. The Pacific coast storm continued to
pound the Washington, Oregon, and California coasts over the weekend, with heavy
rain and winds at Cape Blanco, Oregon, gusting to 59 m.p.h. on Saturday. Snow
fell in the Cascades and the Sierras, and eastward to the Rockies. The low
pressure system centered north of Lake Superior on Saturday, and produced winds
gusting up to 60 m.p.h. and heavy snow squalls on the lee shores of the Great
Lakes. Snow depths up to a foot or more combined with the strong winds made
highway travel difficult. Stormy conditions in the Northeast slackened by late
Sunday as the storm moved toward Nova Scotia. The Pacific storm was still lashing
the Far Northwest with strong winds and rain. Weather of the week continued on
page 827.

HAWAII INSECT REPORT
New State Record - Twenty-one specimens of a GEOMETRID MOTH (Semiothisa santare-
maria (Walker)), a neotropical species, taken from light trap at Halawa, Oahu,
during October and November. On November 4, 1970, two adults collected live on
walls of building at this site by W. Au. Three more specimens collected by D.
Sugawa in dense growth of haole koa (Leucaena leucocephala) at Poipu, Kauai, on
November 13, 1970. Taxonomically, Semiothisa is a large genus, and santaremaria
a notoriously difficult species to determine. The species of the continental
United States have not as yet been adequately studied, and much less is known
about the neotropical species. Determined by D.C. Ferguson. (Kawamura).
Turf - Adults of a SKIPPER (Hylephila phylaeus) moderate on inflorescence of
Lantana sp. in landscaping at Salt Lake, Oahu, where first specimens collected
on Bermuda grass in September. Surveys negative at Moanalua and Honolulu Inter-
national Airport where specimens collected in October. (Kawamura).
General Vegetables - Larvae of BEET ARMYWORM (Spodoptera exigua) light, averaged
I per 3 plants, in 0.1 acre of green onions at Waimanalo, Oahu; heavy in adjacent
0.1 acre of same crop. All stages of GREENHOUSE WHITEFLY (Trialeurodes vapor-
ariorum) heavy in 0.5 acre of snap beans at Waimanalo; generally light in most
other fields of same crop and in 0.25 acre of daikon (Raphanus sativus longipin-
natus) in same area. (Kawamura).
Nuts - COCONUT LEAF ROLLER (Hedylepta blackburni) damage heavy to 80 percent of
coconut trees at Wailua, Waipouli, and Kapaa, Kauai; severely skeletonized fronds
of many trees. (Sugawa).
Forest and Shade Trees - Adults of a PLATASPID BUG (Coptosoma xanthogramma) heavy
on terminals of Erythrina sp. at Kaneohe, Oahu; 80 percent of eggs parasitized by
Trissolcus sp. (a scelionid wasp). Trace on 100+ Erythrina sp. at Keehi Lagoon
Beach Park and 33 similar trees at Makiki. (Au, Kawamura).
General Pests - CHINESE ROSE BEETLE (Adoretus sinicus) damage light to moderate on
foliage of 100+ Erythrina sp. at Keehi Lagoon Beach Park, Oahu. Damage light to
older leaves in 0.5 acre each of snap beans and edible ginger at Waimanalo.
(Kawamura).
Beneficial Insects —- A PUNCTURE-VINE STEM WEEVIL (Microlarinus lypriformis) in-

Weather of the week continued from page 822.
TEMPERATURE: A southwesterly flow of the upper levels of atmosphere brought
unseasonally mild weather to much of the Nation. On Monday afternoon, temperatures
climbed to the 70's from the southern Great Plains to the Atlantic Ocean, and to
the 80's in southern Texas and parts of the Florida Peninsula. Monday afternoon,
a cold front accompanied by winds gusting to 60 m.p.h. and a wall of dust that
reduced visibility to near zero moved into the Great Plains. At midweek, mild
weather continued over the East as subzero weather moved into the northern Great
Plains. At 2 pm Wednesday, the temperature at Cut Bank, Montana was 8° below zero
while persistent southerly winds brought record breaking high temperatures to 21
States from Kansas and Oklahoma to Maine and Florida. Weekly mean temperatures
averaged 12° to 18° below normal in northeastern Montana, 9 to 10° above from
Colorado to West Virginia, and 10° to 15° above normal in Arkansas and eastern
Texas. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING DECEMBER 14
HIGHLIGHTS: Winter cold prevailed along our northern border. It was especially
cold from Pennsylvania to New England. Mild temperatures predominated from Texas
to Virginia. Heavy snow fell from Great Lakes to New England.
PRECIPITATION: Fair weather continued over most of the Nation early in the week.
The exception included light precipitation from the northern and central Pacific
coast to the northern Rocky Mountains, and from the Great Lakes to the Northeast.
For the most part, precipitation was sparse in the first half of the week
although a blanket of fog covered central Oklahoma and much of Louisiana Wednesday
morning. A change of weather pattern began to take shape about midweek. Moist
Pacific air invaded the northern Rocky Mountains. As the storm system moved to
the Great Lakes, another system brought mixtures of snow, sleet, and freezing
rain, creating hazardous driving conditions across Upstate New York and northern
New England. A foot of fresh snow fell at Massena, New York, increasing the depth
at that location to 20 inches by early Wednesday evening, and by early Thursday
23 inches lay on the ground. By late Thursday, a major storm was sweeping across
the Great Plains. Several inches of snow fell from northeastern Nebraska to
southern Minnesota, and by Friday, the snow had spread eastward to the Great Lakes.
A band of rain and freezing rain lay south of the snow belt. Showers and thunder-
storms occurred in the middle Mississippi River Valley. The weekend brought
inclement weather from the Great Lakes to the Atlantic coast. Heavy snow fell in
the northern portion of that area. Madison, Wisconsin, received 16 inches, the
greatest 24-hour amount and the greatest storm total of record for that station.
Freezing rain coated wires, trees, and streets south of the snow area. Rain fell
further south, but parts of the Deep South received no rain. Some areas in Georgia
received rain on Saturday after three weeks of dry weather. Forest fire danger
increased in the rainless areas. By late Sunday, snow fall intensity was decreasing
in the Northeast, but a Pacific storm was approaching the western coast.
TEMPERATURES: Fair weather prevailed over most of the Nation early in the week.
Monday afternoon temperatures in the 60's were common in mid-America as far north
as Nebraska. Montana and North Dakota registered maximums in the 40's. The
Northeast was cool with afternoon readings near freezing. In the Southwest, the
mercury approached the 80° mark with 82° at Thermal, California, and at Tucson,
Arizona. Subzero temperatures occurred in northern Maine Tuesday morning. The
warming trend continued in mid-America with Grand Island, Nebraska, recording
73° Tuesday afternoon. Cooler air moved into the northern Great Plains Wednesday
when much of Montana and the Dakotas remained below freezing. The East warmed at
midweek. Washington, D.C., was about 20° warmer on Saturday afternoon than 24
hours earlier. Weather of the week continued on page 834.

HAWAII INSECT REPORT
Turf and Pastures -— GRASS WEBWORM (Herpetogramma licarsisalis) damage heavy,
larvae 28 per Square foot, to pastures of Kikuyu grass at Honomalino, Hawaii.
Larvae light to moderate in Bermuda and pangola grasses at Pahoa. Larval activity
remains light in pastures on Maui and Oahu; light trap collections at Kaneohe,
Waipahu, and Manoa, Oahu, indicate increase in adult populations in these areas.

WEATHER OF THE WEEK ENDING DECEMBER 21
HIGHLIGHTS: Coldest stormiest weather of the season occurred last week. Roseau,
Minnesota, registered 36° below zero and snow in Washington accumulated to more
than 100 inches above 5,000 feet.
TEMPERATURES: Clear cool invigorating weather prevailed over much of Nation
early in the week. Subfreezing temperatures occurred as far south as the Gulf
States on Monday December 14. Temperatures plunged to below zero at some northern
locations in sharp contrast to 60° temperatures in parts of the South, At 7 a.m,
Wednesday temperatures ranged from 25° below zero at Houlton, Maine, to 74° at
Key West, Florida, A gradual warmup occurred over the East during the week. By
Saturday, maximums were reaching the high 50's and low 60's as far north as the
Ohio River. Sunday was slightly cooler, A cooling trend over the northern Rocky
Mountains and the northern Great Plains dropped temperatures to below zero on 1
or 2 mornings. Big Piney, Wyoming, registered 26° below zero Sunday morning. One
of the coldest temperatures of the week occurred at Roseau, Minnesota, on the
21st, when the mercury plunged to 36° below zero, Temperatures averaged below
normal from the Pacific Ocean to the Great Lakes in the North and to the
Continental Divide in the South, Eastern New York and New England also averaged
cooler than normal, Above normal average temperatures prevailed from Oklahoma and
Texas to the middle Atlantic coast, Most of Montana, Wyoming, and the Dakotas
averaged 6° to 16° below normal,
PRECIPITATION: Precipitation was occurring in three areas early in the week. One
low pressure system centered north of Lake Erie was causing snow flurries from
Michigan to Maine, but accumulations were slight. A low centered over northeastern
New Mexico was dumping snow on the southern Rocky Mountains. A third storm pro-
duced snow in coastal ranges and the Cascades in Washington and Oregon, Precipi-
tation in the Northwest was accompanied by strong winds. Cape Blanco registered
86 m.p.h. gusts Tuesday. Several inland stations recorded wind gusts exceeding
45 m.p.h. By Tuesday morning, typical winter weather had replaced clear skies of
the previous day over much of the Country. At midweek the Pacific storm continued
to batter the Northwest, while another low centered over southwestern Arkansas
dumped heavy snow in eastern Kansas and northern Missouri, Heavy thunderstorms
occurred in the Deep South. By afternoon, precipitation was widespread from the
Mississippi River to the Atlantic Ocean, As the storm moved northeastward
Thursday, it dumped snow at the rate of l-inch an hour at some locations in the
Northeast. Portland, Maine, received 20 inches in 12 hours on Thursday. The
weekend brought rain along the Pacific Coast, snow in the western mountains,
northern border States, and the Northeast, and freezing rain in some areas south
of the snow belt. Light rain or drizzle fell from Texas to the southern Appala-
chians. Weekly precipitation totals ranged up to 4 inches or more along the
