WEATHER BUREAU'S 30-DAY OUTLOOK
JULY 1969

The Weather Bureau's 30-day outlook for July is for temperatures to average below
seasonal normals over the northern third of the Nation and in most areas west of
the Continental Divide. Above normal temperatures are expected over the southern
Plains and the South while near normal values are indicated for unspecified areas.
Precipitation is expected to exceed normal in the Pacific Northwest as well as
from the central Plains to the Ohio Valley. Subnormal totals are indicated for

the central and southern Plateau region, and gulf coast region and most of the
South Atlantic Coast States. Elsewhere near normal rainfall 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 FOR THE WEEK ENDING JULY 23

HIGHLIGHTS: The Northern States were mostly cool, cloudy, and rainy last week.
The South and East were hot and humid, Stormy weather occurred frequently along
the fronts that separated the cold and hot air masses.

PRECIPITATION: Substantial rains fell last week over most Northern States. Totals
of 1 to 3 inches were common over the northern Great Plains but weekly amounts
ranged up to 5 inches in Montana and North Dakota with some local flooding in
Montana. It was the 4th consecutive wet week in Minnesota where weekly totals in
the southern part of the State ranged up to about 10 inches. Lakefield and Worthing-
ton, both in Minnesota, received 7.50 and 6.37 inches, respectively, late on the
28th. A few stations in Wisconsin also registered weekly totals approaching 10
inches. Numerous tornadoes and severe thunderstorms struck from the central Great
Plains to the Great Lakes and eastward to the Atlantic Ocean. On Monday afternoon
winds gusting to nearly 60 m.p.h. Swept the Philadelphia, Pennsylvania, airport
while hail 3 inches in diameter pounded nearby Cherry Hill, New Jersey. Up to 8
inches of rain in north-central Tennessee and up to 9.5 inches in south-central
Kentucky caused severe flooding and drowned 2 persons in Tennessee. Tornadoes
caused $150,000 damage to buildings, trees, and power lines in the Ripley, Perkins,
and Cushing Lake vicinities in Oklahoma on Monday. On Tuesday evening heavy thun-
derstorms dumped 2-5 inches of rain in central and eastern Nebraska. State highway
officials reported a number of roads under water. Several inches of snow fell in
the Colorado Rockies and in Oregon, snow fell as low as 3000 feet. Midweek brought
severe storms from Kansas, Oklahoma, and Missouri northward to Minnesota and
Wisconsin, Winds gusted to 85 m.p.h. at Kansas City, Missouri, and to 90 m.p.h. at
St. Joseph, Missouri, and Winona, Minnesota, St. Joseph received 1.25 inches of
rain in 15 minutes Thursday afternoon, Nine inches fell at Diamond Springs, Kansas.
More destructive storms struck the Central States over the weekend. Numerous heavy
thundershowers, Some accompanied by hail and strong winds, occurred along fronts
that stretched across mid-America from New England to southern Utah. Dry areas
included the Southwest and the Deep South, In parts of the Deep South, this was the
7th consecutive dry week.

TEMPERATURE: Temperatures averaged cooler than normal north of a line from south-
western New Mexico to Lower Michigan and warmer than normal south of that line,
Temperatures from central Oregon to the western edge of the Great Plains averaged
6° to 15° cooler than normal. Most of the South and East as far north as Pennsyl-
vania averaged 3° to 7° warmer than normal, Strong winds reaching 40 to 50 m.p.h
poured unseasonably cool air southward over parts of the West. In contrast, hot ;
humid gulf air flowed northward over much of the eastern half of the Nation, By
the weekend, 90° heat had reached New York and New England. Washington, D.C
registered 100° on Saturday, the highest temperature at Washington since July 3
1966, when the mercury reached 101°. Hundred-degree heat also occurred over the
southwestern deserts, the western edge of the central and southern Great Plains
and the Deep South as far north as the Missouri Bootheel. The high humidity in the
East combined with the hot temperatures made the weather especially uncomfortable

WEATHER OF THE WEEK ENDING JULY 7

HIGHLIGHTS: The Northern States continued cool and comfortable while heat and
humidity intensified in the South. Thundershowers accounted for almost all of the
precipitation.

PRECIPITATION: Local showers fell almost daily along and north of a quasi-
stationary front that stretched from the central Great Plains eastward to the
Great Lakes. The heaviest rains in the early part of the week fell from Kansas

to the lower Ohio River Valley. Some heavy thunderstorms struck the Deep South
early Tuesday and violent winds and damaging hail occurred in the Kansas City,
Missouri, area in the early morning hours on Wednesday. Torrential rains fell from
severe thunderstorms on Friday, from Lake Erie and vicinity to extreme northern
West Virginia. Portions of this area received 4 to 10 inches from the storms. One
severe thundershower caught boaters anchored near Cleveland waiting for the
Holiday fireworks. Many boats were overturned. The storm caused over 33 deaths;
100 persons are still missing and property damage tentatively estimated to run into
several million dollars. Wide areas from California to New Mexico, much of central
Texas, and scattered areas in the Deep South received no rain. In many southern
areas, the showers missed the places where they were needed most.

TEMPERATURE: Heat and humidity intensified over the Southern States during the
past week. Needles, California, registered 115° or higher on several afternoons.
Many stations from the southwestern deserts to Mississippi registered 100° or
higher on Friday and by Saturday, 100° heat pushed northward to the Missouri
Bootheel. Maximums at Washington, D.C., averaged 93°. Weekly temperatures averaged
above norma 1 south of a line from Los Angeles to Boston. Much of the area averaged
3° to 5° warmer than normal. Also, for most of this area, it was the second hot
week. More comfortable weather prevailed in the North with early morning tempera-
tures in the 40's, 50's, and 60's and afternoon temperatures mostly near 80°. In
Minnesota, it was the fifth week with below~normal temperatures. The border States
from Idaho to upper Michigan averaged from 6° to 9° cooler than normal. (Summar

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

A SCARAB (Phyllopertha nazarena Marsuel)

Economic Importance: The species, first described from Israel in 1878, is a seri-
ous peSt Of wheat, other cereals, and many dicotyledonous plants. Severe damage
was observed at Merhavia, Israel, in 1936. Yellow patches began appearing in
young wheat, each patch was about 1/4 to 1 acre in size. Of a field of 550 acres
66 acres were destroyed. In 1938 normal yield of the region was 264 pounds per
0.2 acre while average yield of infested wheatfields was 66 pounds per 0.2 acre.
Larvae feed on roots of young plants, causing loss of vigor, and reducing yield

In some fields, damage to 25 percent has been reported. In Israel, it is known to
be a serious grain pest only in the inland valleys. ‘

Distribution: Israel, Syria, Jordan, and possibly Cyprus.

Hosts: Wheat, barley, other small grains and many dicotyledonous plants.

General Distribution of Phyllopertha nazarena Marsuel

Life History and Habits: In Israel, adult females oviposit in cracks in the soil
during June. Eggs are laid at a depth of 15-24 inches, where temperature and low
humidity cannot affect them. Eggs are dormant until rains begin during November.
Absorption of water causes them to hatch. The larva feeds at night on cereal
roots from December into March; descends into the soil, prepares a cell where it
remains until the first rain in November. The larva molts, crawls to upper soil
levels to feed. This cycle is repeated about two times. After the third cycle,
the larval length has increased to about 30 mm. The larva descends again about
April and pupates. Pupal stage lasts 5-15 days. The young beetle remains in the
cell until the body hardens about late May. Adults emerge 3 years after hatching.
They are active from 8 to 10 a.m. and 4 to 6 p.m., but seek shelter when tempera-
tures go above 27° C. The adults do not feed, and the life span is only 10-20
days. The males fly about searching for females which remain hidden in the soil
and seldom emerge. Males enter the hiding places to mate.

Soil moisture is one of the most important factors governing occurrence and
increase of this species. Moisture is an essential factor in the hatching of the
eggs and the interruption of the larval diapause.

Coleoptera: Scarabaeidae No. 182 of Series

WEATHER OF THE WEEK ENDING JULY 14

HIGHLIGHTS: Northern States enjoyed cool nights and mild afternoons while the
South broiled under cloudless skies with hot afternoons and warm nights. Heavy
rains fell along already flooding rivers and on soaked agricultural lands while
no rain or only widely scattered light sprinkles fell in some of the southern
areas which had endured up to 8 weeks of dry weather.

PRECIPITATION: The precipitation situation last week was, to some extent, a
repetition of the previous week's regime. Heavy thundershowers again fell over

a wide band extending from the central Great Plains to the middle Atlantic coast.
Already soaked lands received additional surplus rain which caused local flash-
floods in Iowa, Kansas, Missouri, and Illinois. Some flooded areas in Missouri
received heavy rains on Thursday: Brunswick, 6.35 inches; Jennings, 6.00 inches;
and Salisbury, 4.88 inches. Meanwhile, parts of the Deep South, where little rain
had fallen in’8 weeks, sizzled under cloudless skies. The weekend brought showers
to southwestern Georgia which had been quite dry. Light sprinkles spotted the Far

Northwest and the Great Basin but weekly totals in those areas were generally of
little consequence.

TEMPERATURE: The temperature regime which persisted in the two previous weeks
changed little in the week ending Sunday, July 13. A polar High over the Great
Lakes brought cool nighttime temperatures to the Northeast. Minimums in the 40's
were common on several mornings. Mild afternoon temperatures, mostly in the 70's
and 80's continued. Another High, stationary off the south Atlantic coast pumped
hot, humid air across the southern Great Plains pushing afternoon temperatures
into the high 90's and, in Some areas, to 100° or higher, and holding nighttime
minimums to the high 70's and low 80's. Sweltering heat intensified across the
South and by the end of the week 100° temperatures had occurred in more than a
dozen States on 2 or more days. Valentine, Nebraska, registered 107° on Saturday
afternoon. Darkness brought slight relief from the oppressive heat and humidity.
The lowest temperature at Kansas City, Missouri, Wednesday morning was 81° and
at Memphis, Thursday, 80°. Temperatures over the West, below normal during the

week, warmed to near normal over the weekend. (Summary supplied by Environmental
Data Service, ESSA.)

BENEFICIAL INSECTS

Establishment of Microctonus aethiops (Nees) in New Jersey - Cooperative survey by
New Jersey Department of Agriculture and U.S. Department of Agriculture showed that
this braconid parasite of alfalfa weevil (Hypera postica) is present in all 13
counties of New Jersey which have significant acreages of alfalfa. Collections of
514 overwintered adult alfalfa weevils in mid-May showed M. aethiops present in 33
of 34 fields. Parasitism averaged 79 percent. (Note: Since these weevils were
nearing end of life span, beneficial effect was not so great as that of second
generation of M. aethiops, which parasitizes about 25 percent of new weevil
adults.) M. aethiops has been released in more than 20 States east of the Missis-
sippi River by U.S. Department of Agriculture and State entomologists. This bra-
conid is known to be established in 7 counties in Pennsylvania, 3 in Delaware, 3
in New York, and one county in New Hampshire. Further survey probably would show
that 7 aethiops is established in many more counties and States. (Day, Metter-

SELECTED REGIONAL LISTS OF NORTH AMERICAN APHIDS

Mortimer D. Leonard 1/

This bibliography has been compiled at the suggestion of Dr. V. F. Eastop, Depart-
ment of Entomology, British Museum (Natural History) as an aid to individuals pre-
paring maps or other material dealing with the distribution of North American
aphids. The papers are, for the most part, those which give only distribution
records although some also include descriptions of new species and new genera,
Distribution data are given in many other papers in which new species and new
genera are described but it is not felt desirable to include the titles of these.
Records of the occurrence of aphids in many States are given in the weekly U. S.
Department of Agriculture Cooperative Economic Insect Report.

Several lists of aphids are nearing completion, These are as follows: Alberta

by A. M. Harper, British Columbia by A. R. Forbes and Oklahoma by H. W. Van
Cleave.

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-JULY TO MID-AUGUST 1969

The Weather Bureau's 30-day outlook for mid-July to mid-August is for temperatures
to average above seasonal normals east of the Continental Divide except for near
to below normal in the northern border States. West of the Divide below normal
temperatures are indicated for the northern half of the area and near normal
elsewhere. Precipitation is expected to exceed normal in northern border States
and also over the southern Rockies. Subnormal totals are indicated for the
Atlantic coast and most of the South except for near normal along the gulf coast.
Little or no rainfall is expected in central and southern California. Elsewhere
near normal rainfall 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 JULY 21

HIGHLIGHTS: Precipitation ranged widely from none in the Far West to flood
producing heavy local downpours in several North Central States.

PRECIPITATION: Widely scattered thunderstorms dropped light amounts of rain from
the Rocky Mountains to the western Great Lakes and along the gulf coast early in
the week. Heavier thundershowers fell in Iowa, northern Illinois, and the middle
gulf coast on Wednesday. Amounts ranged up to 5.5 inches in south-central Iowa and
to more than 5 inches in southern Alabama. Moline, Illinois, received more rain in
the first 18 days of July 1969 than in any previous July of record. Widely
scattered heavy local showers fell Thursday night from North Dakota to the Gulf

of Mexico. A station near Brainard, Nebraska, received 3.50 inches in 20 minutes.
Over 5 inches fell at Beulah, North Dakota, during the night and more than 6 inches
fell in some of Chicago's suburbs. Weather of the week continued on page 585.

10-15. Adults still emerging and will continue to annoy acutely for 3-4 weeks.
Heavy rains July 13 and 15 started 2 new broods of A. vexans, Storm conditions
aided distribution of adult A. vexans from breeding sites, So that heavy popu-

MISCELLANEOUS WILD PLANTS

GRASSHOPPERS - FLORIDA - Nymphs, mostly Schistocerca obscura, severe in 2 large
areas on Everglades Experiment Station June 27, 1969. Development 2-3 weeks
earlier than normal, Heaviest, 15-30 second to last instars per sweep, in 40

acres of elderberry (Sambucus Simpsonii) scrub; bushes 50+ percent defoliated.
Larger nymphs heavily debarked bushes although ample foliage available. Few S.
obscura adults noted. Also infested old 15-acre planting of ramie (Boehmeria _
nivea). Population 98+ percent S. obscura. Few Paroxya sp., Dichromorpha viridis,
Tryxalis brevicornis, Chortophaga viridifasciata auStralior, and Romalea microptera
(eastern lubber grasshopper) also present. S. Obscura infestation in ramie about
half that in elders, but higher percentage of very young nymphs indicated possi-
bility of population equalling that in elderberry stand. Elderberry is noneconomic
wild host and ramie is no longer economic crop in State. Due to noneconomic status
of hosts, controls not contemplated. Infested area is original release site of the
northern Indian black francolin, a game bird, Cultural control would destroy use-
fulness of area aS a francolin covert and probably drive birds to less desirable
habitat. By July 3, grasshoppers had completely defoliated 40-acre elderberry
stand and were moving to pastures and sorghum fields. (Genung, Janes, Lewis).

Weather of the week continued from page 566. :
Over 5 inches fell late Friday afternoon at Gulfport, Mississippi. Sunday morning
brought more than 6 inches of rain to some of Cleveland's suburbs forcing 60
families from their homes. The Far West and the southern High Plains received no
rain or only light widely scattered sprinkles. Light weekend showers occurred in
New England and New York with totals ranging up to about an inch.

TEMPERATURE: Hot humid weather, while maintaining its grip on the South, Central,
and Southeast, spread northward over the Northeast. By midweek, 90° heat

reached New York and New England. Millinocket, Maine, registered 95 on Wednesday
afternoon. Maximums reached the 70's and 80's in the Dakotas and Minnesota in

the "cold" air north of the quasi-stationary front that stretched from the central
Rockies to the St. Lawrence River Valley. A warming trend in the West late in the
week pushed afternoon temperatures into the 90's as far as the Canadian border
with Omak, Washington, registering 90° or higher on the last 3 days. A cooling
trend in the Northeast dropped afternoon temperatures slightly. Weekend maximums
in New York, New England, and Pennsylvania ranged in the 70's and 80's where the
temperatures had reached the 90's earlier in week. Ninety degree heat continued
from Virginia southward. (Summary supplied by Environmental Data Service, ESSA.)

Measuring Insect Infestations
You are aware of the increasing need for more adequate means for measuring insect
populations. As you know, survey methods are available for about 80 pests,
Limitations of some of these methods are recognized, but they do give a common
language. What can be done about the many economic species for which survey
methods have not been developed? With a little effort, we believe a lot can be
done by simply making counts or numerical estimates if actual measurement is not

possible or practical.

A review of the "Cooperative Economic Insect Report" will show that much survey
information is reported in indefinite terms: Heavy, light, medium, moderate,
rather heavy, considerable, troublesome, etc. It would seem that many of these
abstract evaluations could be stated in definite terms such as insects per square
foot, per square yard, per sweep, per plant, per animal. There is also a great
need for more concrete information on insect damage. Compare the following
reports on the same condition: "Approximately 40 percent defoliation in a 100-

acre grove." "'Heavy defoliation in one large grove."

The use of more numerical evaluations in insect survey would greatly improve
communications between entomologists and others interested in survey results.

Such evaluations would also make the data much more useful for records purposes.

We ask your help in improving the quality of reports on insect populations and
their damage. We are aware that only through more research can we have better
methodology in measuring insect populations and damage. Adequate research in this
area is not likely to be forthcoming in the foreseeable future, however. In the
meantime, we believe there are some constructive steps that can be taken to improve

the existing situation.

The guidelines on the next page are offered as a reference for reporting insect
conditions. If you have other suggestions, please send them to the address shown

on the inside front cover of CEIR. They will be appreciated.

Preparation of Notes for Cooperative Economic Insect Report

Requests have been received relative to the type of information desired for the
Cooperative Economic Insect Report.

The report is organized on a principal crop basis. This format is designed to
make the material more accessible and readable. It is hoped this approach will
also stimulate greater participation by pointing out lack of reporting on individ-
ual crop problems. Efforts will continue to be made to evaluate and present the
information in ways to make it more useful in insect control.

Forecasting statements will be developed wherever field reports support such
action. Reporters are encouraged to include this important information in their
notes. The Cooperative Economic Insect Report will focus on the important insect
problems of a regional and national nature. Notes on routine insect occurrence
will be kept to a minimum. Routine notes submitted on common insects will be
added to the National insect files as warranted, however.

The following guidelines are suggested for preparation of notes. It is realized
that all of the information outlined will not be available in each situation, but
give the following information when possible.

1. Common (if available) and scientific name of species involved. Stages
of insect involved. (If a taxonomic problem exists, it should be
noted).

2. Location (definite, recognized area within state, such as region,
county or town), date, name of observer or reporter. If note is for
period other than current reporting period, give date of observation.

3. Host involved, scope and extent of infestation in number of acres,
trees, animals, etc. Also stage of host.

4, Quantitative evaluation of infestation according to recognized survey
methods. Where such methods are not available, give numerical data
such as number per linear foot, per plant, per sweep or per animal.
These data should be based on a representative Sampling. An adjectival
rating Should be accompanied by a numerical rating.

5. Estimation of extent of injury or damage.

6. Comparisons with previous infestations, outlook or predictions for
future infestations, unusual influences.

7. Status of natural or applied control.

8. When reporting new State, United States, or North America records in-
clude the above information insofar as applicable, as well as name of
taxonomist making determination.

Examples of notes including these data are as follows:

EUROPEAN RED MITE (Panonychus ulmi) - Egg populations have reached point
where protective sprays are warranted in 10 percent of apple orchards in
Knox County. Counts on June 30 showed 0 to 4.8 live mites per leaf and
0 to 37.6 eggs per leaf. Further increase and spread expected with
continued favorable weather. (Jackson, July 2).

EUROPEAN CORN BORER (OsStrinia nubilalis) - Oviposition and hatch practi-
cally complete in central counties. Fifty egg masses per 100 stalks in
northwest area. In southern counties, all corn 35 inches or taller, 70

to 100 percent infested with 2 to 22 larvae per stalk. Larvae from first
to third instar. (Smith).

WEATHER OF THE WEEK ENDING JULY 28

HIGHLIGHTS: Mild temperatures prevailed over most northern areas while the South
continued hot. Little rain fell from the Pacific coast to the western Great
Plains. Totals over the eastern half of the Nation ranged widely from a fraction
of an inch to more than 10 inches.

PRECIPITATION: Thunderstorms became widespread early in the week from the

Rocky Mountains to the middle and southern Atlantic coast. Most of ‘the activity
occurred in the hot humid gulf air which covered the South or in connection with
slow-moving cold fronts. Damaging winds accompanied some of the storms; a few
brought hail; and many produced torrential rains. On Monday afternoon and
evening, thunderstorms, with winds gusting to 74 m.p.h. caused flash floods in
the Lubbbock, Texas, vicinity. Thunderstorms occurred in 44 States on Tuesday.
Almost 3 inches of rain fell at Washington, D.C., in 1 hour on Tuesday afternoon.
By midnight more than 4 inches had fallen, flooding low places in many parts of
the city and its suburbs. Over 5 inches flooded parts of Richmond, Virginia.

Over 2 inches fell at Armour, South Dakota, in 20 minutes on Friday and 9.25
inches fell at Waldron, Arkansas, in the afternoon and evening. Two-day totals
(Friday and Saturday) at Leonardtown and Solomons Research Laboratory, Maryland,
were 12.44 and 11.85 inches, respectively. The heavy thunderstorms drenched some
areas which had been previously dry, relieving or ending the serious dryness
which, in some cases, had continued for several weeks. Totals west of the Rockies
were generally of little importance and most of the western Great Plains stations
received less than one-half inch.

TEMPERATURE: Hot sunny weather prevailed over the Southwest with maximums at
interior stations of California climbing to 100° or higher on 1 or more days.
Maximums reached the 90's in central and eastern Washington on several days.
Hot humid weather continued over the South with little day-to-day temperature
change. Mild temperatures near the Great Lakes were replaced by cooler weather
at the end of the week. New England and New Jersey remained cool with little

cena temperature change. (Summary Supplied by Environmental Data Service,

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE

ARMYWORM (Pseudaletia unipuncta) - NEBRASKA - Spotted and heavy local infestations
of second-generation larvae from central, east, and northeast crop districts and
panhandle area. (Keith). SOUTH DAKOTA - Economic in southeastern area; first
reported July 19. Areas included portions of northern Union and Clay Counties,
Yankton County, southeastern Bon Homme County, southern Lincoln and Turner
Counties; infestations spotty in southwestern Aurora County. Infesting mostly
oats damaged by hail and still green compared with surrounding fields. Damaged
corn in Bon Homme and Union Counties. Crossing State Highway 50, southeast of
Tyndall, Bon Homme County. Damage expected to continue and become more wide-
spread in areas which remain untreated, since larvae range from first to fifth
instar. Economic in Minnehaha, Moody, and Beadle Counties. Moths still taken in
blacklight trap at Brookings, Brookings County. (Jones, Kantack). MINNESOTA -
Economic in southern Nobles and Rock Counties; ranged 4-20 per square foot in

Quarterly Citrus Insect and Mite Outlook in Florida - June through September -
This outlook is based on the assumption that weather beyond the period of the
current U.S. Weather Bureau's 30-day Outlook will be normal, Therefore, the fore-
casts given below cannot be viewed with the same degree of contidence as those in
the "Insect and Disease Summary" usually released twice each month,

CITRUS RUST MITE expected to continue abnormally high until mid-August, then
decrease to low level in September. CITRUS RED MITE and TEXAS CITRUS MITE normal
and unimportant. BLACK SCALE will be abundant through July, then decrease. Young
crawlers expected to be numerous late in August but most will die. GLOVER SCALE,
PURPLE SCALE, YELLOW SCALE, and CHAFF SCALE will be present in majority of groves
but will likely be important in less than 10 percent. Decrease to low level
expected August through September. Unaspis citri likely to be found in new areas,
WHITEFLIES expected to be above normal and in high range through July, then
decrease to low level. MEALYBUGS will continue high through July, then gradually
decrease to low level in August and September. (W.A. Simanton),

ALABAMA - Culex pipiens quinquefasciatus larvae and adults increased sharply around
homes statewide, Recent rainS partly filled containers and provided extremes in
breeding places. (McQueen). OHIO - Wet spring and early summer brought about
unusually high counts. Heavy rain of July 4 and subsequent lesser showers virtually
created population explosion. Water enough in northern area so that biting should
be aS bad or worse for next 2-3 weeks. Aedes trivittatus daytime nuisance in corn-
fields and hayfields in northwestern area. Daytime bites per hour: 30 (moderate)
at Defiance, Defiance County, 150 (high) at Essex, Union County, and 200-300 (very
high) at Wauseon, Fulton County. Will continue very irritating in northern area

and St. Paul week ending July 19. Of 14,861 females in 16 traps, Aedes vexans
1,034 and Mansonia perturbans 3,415. Decreased in traps since July 19 so that peak
may already have been reached. Trap collections for week ending July 20, 1968,
totaled 35,000 females with over 55,000 in previous week. A. vexans now in 275 of
415 larval collections. Of 256 females in 21 evening bite collections, A. vexans
187 and Mansonia 17. Of 1,615 adults in 122 field samplings, A. vexans T,064,
Adults of hatch from heavy July 13 and 15 rains emerged July 30-22. Dispersal
will occur July 23-27 and moderate increase can be expected in Twin City metro-
politan area. Adults that emerged weekend of July 4 now passing out of picture
but being replaced by fresh adults from later broods. Unsuccessful control con-
tinues. (Minn. Pest Rpt.).

TABANID FLIES - OKLAHOMA - Tabanus spp. averaged less than 1 per head on Payne

FIG PSYLLID (Homotoma ficus (L,))

Economic Importance: A medium to heavy population of this large psyllid was
found on black miSSion fig, Ficus carica, in a yard in Concord, Contra Costa
County, California, on July 21, 1969, by c. Boissonou. Determination was by
R.F. Wilkey and confirmed by L.M. Russell. The evidence of damage and the
population indicate H. ficus may be a potentially Serious pest of fig in
California. The damage caused by this psyllid in the Mediterranean countries
where it is native is considered of little importance; the buds sometimes
open irregularly but this condition causes no appreciable damage to the host.

Host Plants: Cultivated and wild figs.

Distribution: France, Greece, Iran,
Italy, Lebanon, Libya, Syria, and Tunisia.
Also reported from Spain, Algeria, and
Dalmatia (Yugoslavia),

Life History: In France, adults are found
from June until the first cold weather in
autumn. They rest on the foliage and are
easily disturbed. Eggs are laid at the
end of Summer in the cracks formed by the
bud scales and are attached to the cuticle
by a stalk. Eggs also can be found on the
wood immediately below the bud. They are
laid singly, but are so numerous they
appear to be laid in regular rows. The
eggs are easily seen. They pass the winter
without hatching. At Antibes, eggs have
not been observed to hatch before the
first of April or when buds are swelling
and beginning to burst. Nymphs develop
rapidly (30-45 days). The early stages
feed on the buds. Later, nymphs move out
on the leaves where they are found on the
lower surfaces and along the veins. Adults
begin appearing in late May. There is only
Forewing and adult male one generation a year in the south of France.

A Trap for Tarnished Plant Bug Survey
A. L. Scales 1/
The trap described below for survey of tarnished plant bug (Lygus lineolaris) is

a modification of a trap designed by F.E. Strong, University of California, Davis,
California.

Adult virgin females (usually 10) used as bait are placed in the trap when
approximately 6 to 10 days old. Green beans are used as food for the bugs.

A half-gallon ice-cream container serves as the body of the trap (fig. 1). Both
ends of the carton are fitted with removable funnels fashioned from 16-mesh
aluminum screen. The screen funnels are pointed inward.

The bait insects are housed in a 40-dram plastic vial. Two windows are cut in

the vial. An aluminum screen cylinder fitting snugly against the side of the

vial is inserted. A stoppered hole in the vial is used for introducing the insects.
The green beans are wrapped in absorbent paper, placed in a one-ounce cup,

watered, and inserted in the plastic vial. The cap of the plastic vial is used

to close the open end of the cage.

A hole, slightly smaller than the diameter of the vial, is cut in the side of the
carton, and the vial is inserted. The inner surface of the carton is coated with
a Stikem to prevent trapped insects from escaping through the openings of the
funnels. :

The assembled trap is tied to a pole, and placed even with, or slightly above,
the plants growing in the area to be surveyed (fig. 2).

WEATHER OF THE WEEK ENDING AUGUST 4

HIGHLIGHTS: A large High brought a marked change in the weather over much of the
East. Pacific air cooled the Pacific coast but interior portions of the West
warmed to near or above 100° as the week progressed. Moderate to heavy local
showers spotted much of the East.

PRECIPITATION: Precipitation diminished over much of the Central and East early
in the week as a large High moved into that area. Heavy Showers persisted in the
Northeast and middle and southern Atlantic coast, however, as a slow-moving

front continued to squeeze copious moisture from the warm humid air. A sudden
downpour dumped over 2 inches of rain at Wappingers Falls, New York, in a short
period Wednesday morning and over 7 inches fell at Mt. Washington, New Hampshire,
in the 24-hour period ending at 8 a.m. Wednesday. By midweek, thunderstorms were
occurring along a front which extended from the western Great Lakes to. the
central Great Plains and a few isolated thunderstorms developed in the central
Rocky Mountains. The weekend brought heavy thundershowers along the eastern sea-
board and parts of the Deep South. Many weekend storm totals exceeded 4 inches
causing flash flooding and erosion. While much of the South became too wet, local
areas were missed by the generous showers and need more rain. No rain or only
light showers fell over most of the West.

TEMPERATURE: The Far West warmed daily to near or above 100°. Temperatures at
some desert locations ranged from the 90's at night to 110° in the afternoons.
Several stations in Arizona, California, and Nevada registered maximums from
WIZ" Fo WY” om Thursday af cerioon! Ocean breezes kept afternoon temperatures
along the northern Pacific coast in thé 50's and 60's in sharp contrast to the
90's recorded a short distance inland. Cool weather continued over the Central
States for the second consecutive week. A large High centered over mid-America
early in the week brought cooler, less humid air to much of the East ending the
Sweltering weather in that area. Warm humid weather persisted in the Deep South
and along the southern Atlantic coast. Temperatures dropped slightly in the
Southeast over the weekend but the humidity increased due to the numerous
showers. (Summary supplied by Environmental Data Service, ESSA.)

FLEA BEETLES OF THE GENUS CHAETOCNEMA (CHRYSOMELIDAE)

Four of the 30 species in North America are injurious to various crops, with corn,
sorghums, and small grains most frequently damaged. These four species are the
sweetpotato flea beetle, C. confinis Crotch, the toothed flea beetle, C. denticu-
lata (Illiger), the desert corn flea beetle, C. ectypa Horn, and the corn flea
beetle, C. pulicaria Melsheimer. Larvae of these beetles feed on roots of the
host Dlant, and the adults chew small holes in the leaves. Some species of these
beetles disseminate the bacterium causing Stewart's disease of corn.

A combination of characters is diagnostic for members of this genus. They are
dark colored, jumping beetles 1.3 to 3.5 mm. long. The Chaetocnema are the only
North American flea beetles of this size with the elytral punctures in distinct
rows (at least laterally) and with the apex of the hind tibiae broadly notched
and with a comb of bristles (see below). The tiny figure below the lateral view
equals actual size.

WEATHER OF THE WEEK ENDING AUGUST 11

HIGHLIGHTS: Summer heat continued in the West while more comfortable temperatures
prevailed in the East. Isolated light showers fell in parts of the West. In the
East, scattered thundershowers occurred early in week with heavier, more general
rains over the weekend. Killer tornadoes struck Minnesota and Ohio.

PRECIPITATION: A Slow-moving cold front, which moved from the Appalachian ridge
to the Atlantic coast, produced some generous showers and thunderstorms along
the Atlantic seaboard early in the week. About 3 inches of rain fell at
Chattanooga, Tennessee, in 1 hour Tuesday evening. At midweek, a cold front edged
into the northern Great Plains. Some killer tornadoes occurred in Minnesota
Wednesday afternoon. The tornadoes killed 15 persons, injured many, and caused
property damage estimated at $5 million. Up to 5 inches of rain fell 6 miles
south of Crookston, Minnesota, and hail 1 inch in diameter caused total damage
to crops 10 miles northeast of Hillsboro, North Dakota. A band of showers with

a mixture of turbulent weather occurred from Michigan to Kansas. The weekend
brought more violent weather to parts of mid-America. Severe thunderstorms, some
with hail or heavy showers, and a few tornadoes occurred across Indiana and Ohio
Saturday night. One of the worst left a path of destruction 0.25 mile wide and

7 miles long in the Cincinnati area on Saturday. It killed 4 persons, injured
235, and caused property damage estimated at $7 million.

TEMPERATURES: The warming trend in the Far Northwest continued after a brief
interruption early in the week. Afternoon temperatures in Montana, in the 90's
on Monday, dropped to the 70" s and 80's on Tuesday, but climbed to the upper
90's by Sunday reaching 99° at Havre. Sweltering heat continued in the desert
Southwest. On Monday afternoon, Palm Springs, California, registered 121°, the
hottest temperature in the Nation so far in 1969. Maximums in parts of the
desert averaged above 110°. Much of the area from southern California to the
central and southern Rocky Maui taal S averaged several degrees above normal.
Southerly winds warmed mid-Ameri@a early and late in the week with maximums in
the 90's from the Dakotas to Oklahoma and above 100° over most of Texas by
Sunday when Waco registered 109°. Near seasonal temperatures prevailed over most
of the East. Temperatures were especially pleasant over the Northeast where some
warmup occurred at midweek followed by a cool comfortable weekend. Temperatures
from Alabama to South Carolina averaged a few degrees cooler than normal.

Missouri River. Damaged crops now include flax. New areas west of Missouri River
reported near Hot Springs, Fall River County, and at Sturgis, Meade County. South-
eastern areas, in southern Lincoln County, observed feeding on silks of corn;

no estimate of damage made, although 20 percent of ears with silks contained
larvae, and ranged second to fifth instar. (Jones, Kantack). NORTH DAKOTA -
Scattered in west-central and southwest counties. Infestations in hail-damaged
areas; numbers highest where hail damage most severe. On 1,280-1,920 acre area

Larvae 60 per square foot in margins of some adjacent corn and oatfields.
Severest damage occurred to oats where 100 percent of leaves stripped in parts

of some fields. Corn also damaged, 20 rows from edge in Dunn County. Larvae

ranged 2-30 per square foot in 3-4 township areas near Lefor; oats, barley,
wheat, and millet main crops damaged. Larvae feeding on heads after stripping
leaves in some oat and wheatfields. Also, swathed oats, cut for hay, had up to

80 larvae per square foot under windrows. Up to 90 percent of oat kernels clipped
in Stark and Hettinger Counties. Larvae ranged 3-30 per square foot in 6 township
areas south of Beach in oat and wheatfields; 90 percent of plants defoliated in
some fields in Golden Valley County. In all areas crops are regrowth from hail
damage and in flower to milk stage of development. Larvae vary in size from less
than half inch to 1.5 inch. Controls applied and effective. (Brandvik).

southern area; Spraying before combining required in some fields. Alfalfa and
other legumes "'seeded-down" with small grain damaged in some southwestern
counties after grain harvest; some fields sprayed. Damaged mostly weedy corn

in Rock,Pipestone, Nobles, and Wright Counties; damage severe in some fields.
Oat losses in southwestern area ranged 10-60 percent. Heavy; damaged about 5,000
acres, with about 1,000 acres sprayed in Chippewa County. High numbers picked up
in swath and plugging sieves in combines in southwest district. Some storage
bins topped with crawling larvae. Problem not over; expected to become more
evident in corn with larval growth and migration. Many full-grown larvae and
pupae but all sizes present and feeding. (Minn. Pest Rpt.). IOWA - About 5 per-
cent pupating July 30 in Lyon County; 30-50 percent smaller than 1 inch. In l

total loss of some grain fields in Dodge County to stripping of seedings in
Grand and Lafayette Counties. Larvae ranged 40 per square foot and 45 per corn
plant to less than 1 per 10 row foot. Infestations often spotty and dependent
upon site at time of oviposition, Larvae ranged about one-half inch to pupae;
most about half grown. Parasitism less than 3 percent in all areas. Parasitism
by a tachina fly, Winthemia quadripustulata, most noticeable; few cocoon masses
of Apanteles militaris in SpotS. Diseased larvae numerous in some fields but less
than 10 percent in most. Pea harvest essentially over and where controls applied
early enough results favorable. Corn seldom if ever damaged too severely. (Wis.
Ins. Sur.). MICHIGAN - Reported feeding on field corn last period. Problem on
field corn very mild, except for few fields. Bacterial disease beginning to take
some of larger larvae. (Janes, Aug. 4). Recovered 210 moths in blacklight traps

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-AUGUST TO MID-SEPTEMBER 1969

The Weather Bureau's 30-day outlook for mid-August to mid-September calls for
temperatures to average below seasonal normals in the southeastern quarter of
the Nation and also in the Pacific Northwest. Above normal temperatures are
indicated for the Southwest as well as from the Northern Plains through the
Northeast. In unspecified areas near normal temperatures are in prospect.
Precipitation is expected to exceed normal over the Atlantic coast and east
Gulf Coast States as well as over the northern Plains, the Pacific Northwest
and the Great Basin. Subnormal totals are expected in western portions of the
southern and central Plains and in the upper Great Lakes Region. Elsewhere near
normal rainfall is indicated.

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 18

HIGHLIGHTS: Hurricane Camille moved inland across the Mississippi coast. Hot
weather with only widely scattered light showers occurred over the West.
Temperature and humidity increased in the Northeast.

HURRICANE CAMILLE: Camille moved inland Monday with destructive winds, high
tides, and heavy rains. Gusts at Bay St. Louis, Mississippi, were estimated at
190 m.p.h. The winds and high tides (highest water 20 feet) caused extensive
property damage -- estimated in the millions of dollars. At least 50 persons lost
their lives and many more were injured due to the storm. It is too early to give
an accurate estimate of lives lost, injuries, and storm damage. Weather of the
week continued on page 665.

COTTON

BOLL WEEVIL (Anthonomus grandis) - OKLAHOMA - Punctured squares ranged up to 70
percent in Beckham, Kiowa, and Jefferson Counties. Averaged 4 percent in Tillman
and Marshall Counties; light in Bryan County. (Okla. Coop. Sur.). ARKANSAS -
Infested 4,469 or 71 percent of 6,299 fields; of this,1,770 or 28 percent above
recommended treatment level. (Boyer, Barnes). LOUISIANA - Remains light in most
Madison Parish fields. Punctured squares ranged 1-10 (averaged 2.9) percent in
100 fields; none found in 6 fields. None collected in wing traps. (Cleveland et
al.). MISSISSIPPI - Averaged 0.5-10 percent in 289 cotton fields in 4 western,
1 southwestern, 2 central, and 2 northeastern counties. (Sartor). Punctured

Weather of the week continued from page 656.

PRECIPITATION: Mostly fair weather prevailed early in the week. A few light
Showers fell along the gulf and southern Atlantic coasts in the first part of
the week; also some widely scattered Showers in the northern and central Rocky
Mountains. Thunderstorm activity increased after midweek. Strong winds and hail
accompanied some of the storms in the northern Rocky Mountains and in the
southern Great Plains. Almost 6 inches of rain fell at Kansas City, Missouri,
Friday morning. Strong winds filled the air with dust in the irrigated valleys
in southern Arizona during the week. Rainfall totals west of a line from western
Texas to Lake Superior was generally of little importance. Wide areas in the
Far West received no rain or only light sprinkles. Weekly totals ranged widely
over the South Central and East, generally from less than 0.5 inch to about 2
inchés but with spots receiving more than 2 inches.

TEMPERATURE: Hot sunny weather continued over the Southwest and much of the
Great Plains. On Monday afternoon, temperatures climbed to 100° or higher from
Minot, North Dakota, to Scottsbluff, Nebraska. It was the warmest week of the
year in North Dakota. Most of Texas broiled under 100° heat and maximums in the
southwestern deserts ranged from 105° to 115°. This was the second week of
sizzling temperatures in the Southwest and in Texas. More comfortable tempera-—
tures prevailed over the Northeast early in the week but a warming trend with
increasing humidity caused some discomfort as the week progressed. Temperatures
averaged near normal in the Northwest and slightly below normal in the Southeast.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

ORIENTAL RED MITE (Eutetranychus orientalis (Klein))

Economic Importance: Heavy infestations of this tetranychid mite have occurred

on citrus in Ethiopia and Iran. The species prefers citrus leaves, sucking the
sap from the upper side of the leaf. The chlorotic leaves appear finely stippled
and silvered. As the leaves drop from-the tree, the twigs and branches dry. As

a result of defoliation by the oriental red mite, very young trees die but older
trees lose the outer branches. In Severe cases, the species may affect blossoming
or fruit set. Under drought conditions, damage from a light infestation may be

as serious as from a heavy one.

Distribution: Aden, Afghanistan, Cyprus, Egypt, Ethiopia, India, Iran, Israel,
Jordan, Libya, Republic of South Africa (eastern Transvaal), Sudan, and Taiwan.

Eutetranychus banksi (McGregor) is restricted to North and South America. Old
World records of E. banksi refer to E, orientalis.

Hosts: Castorbean, chinaberry, citrus (prefers lemon), date palm, fig, frangi-
pani, lebbek, papaya, pumpkin, squash, walnut, white mulberry, and other plants,

General Distribution of Eutetranychus orientalis (Klein)

Life History and Habits: Under conditions in Israel, females oviposit along the
midrib on the upper Side of the leaf but in winter may deposit eggs on the lower
side. Up to eight eggs a day or 35 in a lifetime may be deposited by one female,
Under optimum laboratory conditions, eggs hatch in 2,5-3.0 days. Immature
stages are six-legged larvae, eight-legged protonymphs, and deutonymphs. Males
develop from unfertilized eggs. Depending on the season, an adult emerges in 7
to 24 days and lives for 12 to 21 days. Up to 18 generations a year have been
recorded, Climatic conditions which favor the development of this mite are high
temperatures ranging from 69.8° to 80.6°F. and a medium relative humidity
ranging from 59 to 70 percent. Temperature appears to be more influential than
relative humidity. Low relative humidity affects egg survival but has no effect
on other stages.

Acarina: Tetranychidae No. 183 of Series

WEATHER OF THE WEEK ENDING AUGUST 25

HIGHLIGHTS: Hot weather continued in the West while the coolest temperatures
Since Summer began occurred in parts of the East. Much of the West continued
dry. Thundershowers brought needed moisture but some local flooding in the
Great Plains. Estimates of deaths and destruction from Hurricane Camille and
the remnants of that storm continued to increase.

PRECIPITATION: Wide areas in the western half of the United States were missed
by the scattered light showers that fell in that part of the Nation. Where rains
fell, weekly totals ranged mostly from 0.1 to 0.5 inch but up to an inch or so
fell in spots in Utah and up to 3 inches fell in northeastern New Mexico.
Moderate to heavy Showers fell in the Great Plains. Thunderstorms produced some
3-inch showers in North Dakota and a few localities in Kansas received more than
5 inches. Minor flooding occurred in the Lawton, Oklahoma, vicinity following a
4.60-inch shower Friday evening. Also on Friday evening 3 to 8-inch rains in

the Burlington and Stratton area of Colorado produced local flooding. Showers
were both frequent and generous over most of Texas in the latter half of the week.
Only light rain fell from Wisconsin and northern Illinois eastward to New
England. Frontal showers occurred along the Ohio River. Much of the heavy rain
in the Southeast fell in connection with Hurricane Camille and the remnants of
that storm.

TEMPERATURE: Hot sunny weather continued over the western half of the Nation
throught the week. Afternoon temperatures soared to 100° or higher over the
interior valleys of California on several days early in the week, over the
southwestern deserts on almost every day, most of Texas on several days, parts
of Oklahoma on 1 or 2 days, and in Montana on 2 or 3 days late in the week.
Temperatures averaged 6° to 10° above normal over Montana and 2° to 5° above
normal over most other Western StateS. Cool comfortable weather covered most of
the Northeast from Minnesota to New England and as far south as the Ohio River.
In this large area, early morning temperatures ranged mostly in the 40's and
50's and afternoon maximums mostly in the 70's and 80's. Minimum temperatues in
the 50's were common in eastern Tennessee and South Carolina on 2 days late in
Weather of the week continued on page 685.

WEATHER OF THE WEEK ENDING SEPTEMBER 8

HIGHLIGHTS: Stifling summer heat and humidity continued in East. West ranged
from moderately cool in Washington and Idaho to 100° or warmer in southwestern
deserts. Spotty thundershowers ranging from light to excessive were widespread
over the eastern two-thirds of the Nation.

PRECIPITATION: Showers and thunderstorms covered the southeastern half of the
Nation early in the week in connection with a cold front that stretched from the
Northeast to the Texas Panhandle and in the hot humid air southeast of the front.
Amounts ranged widely from a fraction of an inch to about 4 inches with a few
totals approaching 6 inches. Heavy downpours in the El Paso, Texas, area Monday
afternoon and evening flooded one highway and washed out another. On Wednesday
afternoon, one inch of rain in a few minutes swamped buildings at Bettendorf,
Iowa. A 6-inch rain, the largest l-day total since 1944, at New York City

caused local flooding. Much of the East received light showers on almost every
day.

TEMPERATURES: Cool, sunny, pleasant weather prevailed over the northwestern half
of the Nation while hot, humid, gulf air covered the southeastern half. A front
separated the air masses. Temperatures reached the 90's in Montana and western
North Dakota Tuesday afternoon after which a cooling trend dropped minimums to
the 40's and 50's over the 2 northern tiers of States from the Pacific Ocean to
Wisconsin and Iowa. Subfreezing temperatures occurred on several nights in some

of the higher valleys in northern and central Rocky Mountains. Big Piney, Wyoming,

registered 17° on Friday morning. Temperatures averaged several degrees above
normal over much of the Southwest. Maximums reached 105 in the central valleys
of California and 117° in the desert valleys. Overnight minimums in the East
ranged from the 60's in the Northeast to the 70's in the Deep South. Maximums in
the 80's were common over most of the East but exceeded 90° in parts of the

Deep South on a few afternoons. Much of the area from Minnesota to southern New
England and as far south as Maryland averaged 5° to 9° above normal. Light winds
and high relative humidity made the air feel stifling in some areas, especially
Sd were frequent. (Summary supplied by Environmental Data Service,

WEATHER OF THE WEEK ENDING SEPTEMBER 15

HIGHLIGHTS: Summer lingered in the West as a touch of autumn spread over the
hast. Rains were widely scattered and mostly light except in the southern High
Plains of Texas and in coastal New England.

PRECIPITATION: Light rains fell over the Atlantic Coastal States early in the
week. The rains were heavier along the coastal portions of New England with totals
up to 4 inches in Maine as Hurricane Gerda moved northeastward along the coast.
Showers continued from the central and southern Rockies to Texas in the warm
moist air which moved northward around the western edge of a High. This was the
4th consecutive week with generous thundershowers in Texas. The extremely moist
tropical air spread into Arizona and southern California with light showers and
thunderstorms occurring on several days. A few snowflakes were seen at Sault Ste.
Marie late Wednesday night and scattered thundershowers developed in the central
Great Plains from eastern Nebraska to southern [llinois. Norfolk, Nebraska,
registered 1.13 inches but most stations received less than an inch.

TEMPERATURE: Warm Summer weather and widespread sunshine lingered in the Northwest
with maximums mostly in the 80's and 90's. Several stations in Washington and
western Montana registered maximums in the 90's at midweek. Summer heat also
continued in the interior valleys of California. Red Bluff recorded 102° on
Tuesday and 103° on Wednesday. At numerous desert stations, the mercury soared to
above 110°. It reached 114° at Thermal and Palm Springs, California, on Tuesday.
Southerly winds on the western side of a High carried warm moist air across Texas
to the central Rockies and a northerly flow brought a touch of autumn far south-
ward over the eastern part of the Nation. Birmingham, Alabama, registered 48° on
Thursday morning. Summer temperatures continued in Florida. A strong cooling trend
late in the week dropped temperatures sharpiy in Montana with subfreezing minimums
becoming general in the western valleys by Monday morning, September 15. Weekly
averages, however, were 6 to 10° warmer than normal. A warming trend in the East
produced mild weather by Sunday. The sunny skies and warm temperatures were
general over the East by the weekend but weekly averages were below normal. A
large area from the Ohio River to the Gulf of Mexico averaged 6° to 10° cooler
than normal. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER FOR THE WEEK ENDING SEPTEMBER 22

HIGHLIGHTS: Three areas received generous rains: The central Great Plains early
in the week; the Far Northwest at midweek; and the Southeast Saturday and Sunday.
Most rainy areas averaged slightly cooler than normal.

PRECIPITATION: Heavy showers and thunderstorms occurred along and ahead of a
front that stretched from the Great Lakes to the central Rocky Mountains early in
the week. The 2 to 3 days of heavy rains flooded many roads in Oklahoma on
Tuesday and by Wednesday flash flooding was occurring along some streams in
Kansas, Oklahoma, Missouri, and Illinois. By midweek, as the front moved south-
eastward, showers fell from the Great Lakes to the Gulf of Mexico and the
Atlantic coast. Meanwhile, an intense storm off the coast of southern British
Columbia was bringing rains to the coastal portions of Washington, Oregon, and
northern California. Totals ranged from light sprinkles in northern California

to over 5 inches at Quillayute, Washington. A tropical depression dumped 6 to 14
inches of rain on the eastern portion of the Florida Panhandle with local flooding.

TEMPERATURE: Cool polar air pushed into the northern Rocky Mountains early in
the week with minimum temperatures falling into the 20's on Monday morning in
northern Idaho and western Montana. A front stretched from the Great Lakes to the
central Rockies. The weather ahead of the front was warm, humid, cloudy, and
rainy. Cooler, drier, sunny weather followed the front as it advanced southeast-—
ward moving off the coast in the latter part of the week. The Far West cooled
during the week with much of California averaging 2°-6° below normal and about 10°
cooler than the previous week. Temperatures in Montana warmed to the 80's by
Wednesday before the cool rainy weekend dropped afternoon temperatures to the 50's
and 60's. Temperatures averaged slightly above normal over the northern Great
Plains and from eastern Texas to Mississippi and below normal in the Far West,

in the central Great Plains, and from Alabama to New England. (Summary supplied
by Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING SEPTEMBER 29

HIGHLIGHTS: Summer lingered in the western half of the Nation as autumn advanced
Over the East. In some eastern areas this was the third week of typical autumn
weather. Frontal thundershowers dotted much of the East.

TEMPERATURE: A series of fronts crossed the northern half of the country during
the week, each followed by a surge of cool, fresh, dry air. Subfreezing tempera—
tures occurred in the higher valleys in the Rocky Mountains on a few mornings

and Spencer, Iowa, registered 32° on Wednesday morning. More uniform temperatures
prevailed over the southern portions of the United States with afternoon maximums
mostly in the 80's and early morning minimums mostly in the 60's. The Southwest
continued hot. The temperatures at desert locations ranged from the high 90's

to a few degrees above 100° on most afternoons. Weekly ‘temperatures averaged above
normal from the Pacific Ocean to the western Great Plains and along the gulf
coast and below normal over the rest of the Nation. Parts of the Great Basin
averaged 3° to 7 below normal. A large area from the Great Lakes to central
Alabama averaged 3° to 6 below normal.

PRECIPITATION: Low-lying areas, many Secondary roads, and a few main arteries

in northwestern Florida became flooded following the torrential weekend rains in
the panhandle. Storm totals at Quincy and Litman were 18.41 and 21.5 inches,
respectively. Showers and thunderstorms covered much or the eastern third of the
Nation on Tuesday in the warm humid air in advance of a cold front that stretched
from the Great Lakes to the southern Great Plains. As this front moved to the
Atlantic Ocean, other fronts crossed the northern Great Plains bringing clouds
and mostly light to moderate showers. On Friday evening, however, a disturbance
brought torrential showers to north-central and northeastern Kansas producing
local flash floods along some of the streams. The Southern States remained mostly
cloudless and free from rain during the latter half of the week, except Florida
which received torrential thundershowers Sunday afternoon and evening. Pacific
storms brought light rains to the Far Northwest -- up to 4 inches along the
Washington coast and lesser amounts inland and farther south along the coast.
Most of the area from California to the central southern Great Plains received

no rain or only light sprinkles. Rainfall over the eastern half of the United
States ranged widely from light sprinkles to 2 to 4 inches due to the spotty
showers. Alabama received only light sprinkles. (Summary supplied by Environmental
Data Service, ESSA.)

WEATHER OF THE WEEK ENDING OCTOBER 6

HIGHLIGHTS: An early winter storm brought freezing temperatures to much of the
West and deep snow to the central Rockies. Torrential showers fell in Texas and
much of the South received soaking rains.

PRECIPITATION: Rain continued in the Far Northwest and, after midweek, snow fell
in the higher Rockies accumulating to 4 inches at Leadville, Colorado, by Friday
morning. A storm system brought showers and thunderstorms from the northern and
central Great Plains to the Great Lakes at midweek. Widespread rains occurred from
the Ohio River and the middle and eastern gulf coast in connection with a low
pressure system which moved inland at midweek. Torrential weekend rains caused
local flash floods in southwestern Kansas and between Del Rio and San Antonio,
Texas. Weekly totals ranged up to 5 inches in Kansas, and Uvalde, Texas, measured
12.70 inches Sunday morning. A weekend snowstorm dumped heavy snow in the North-
west and in the central Rocky Mountains. Snow fell above 4,000 feet in Washington.
It accumulated to 1 to 3 inches above 7,500 feet in southern Idaho. Denver,
Colorado, received 16 inches and more than 2 feet fell in the foothills west of
Denver.

TEMPERATURE: Autumn chill covered much of the East early in the week. Temperatures
dropped into the 40's Monday morning as far south as Tennessee. Beckley, West
Virginia, registered 34° Monday morning. There was a touch of frost from Michigan
to the central Appalachians. Mild weather continued farther south. On Tuesday
afternoon southerly current boosted the temperatures into the 90's as far north

as Kansas where Russell registered 97°. In sharp contrast, maximums in the Red
River of the North Valley remained in the 40's -- 42° at Devils Lake and Grand
Forks, North Dakota. Wintry weather pushed into the Northwest late in the week
with subfreezing temperatures occurring as far south as central Arizona and north-
western New Mexico. The cold air surge brought the coldest weather of the season
to much of the West. This contrasted sharply to the above normal temperatures
which have prevailed in most of the West for several weeks. The southwestern
deserts were not quite so warm after midweek with maximums in the 90's where
afternoon temperatures had climbed to above 100° on the first -3 afternoons.

The central Great Plains averaged warmer than normal in spite of the sharp

change to cooler weather over the weekend. A large area from eastern Oklahoma

to southern Wisconsin averaged 6° to 10° warmer than normal. (Summary supplied by
Environmental Data Service, ESSA.)

WEATHER OF THE WEEK ENDING OCTOBER 13

HIGHLIGHTS: A major storm brought heavy snow to 9 States, flood-producing rains
to several more, and the coldest temperatures of the season to the central and
southern Rocky Mountains.

PRECIPITATION: Early in the week, a large High, centered over the central Rocky
Mountains, brought fair weather to the western half of the Nation while another
ridge of high pressure extended from northern New England to the Carolinas.
Showers fell on Monday from lower Michigan to Texas along the cold front that
separated the Highs. As the front moved eastward, the precipitation zone moved
eastward also. Flood-producing showers fell in Louisiana Monday night -- 10.50
inches at Oaknolia in 12 hours. As a Pacific front approached the western coast,
gale winds pounded the shore from Washington to northern California and sub-
stantial rain fell in the Northwest. Snow began falling in the Colorado Rockies
late in the week and by late Sunday, a major autumn storm was affecting a 9-State
area. The storm brought 2 feet of snow to a foothill area southwest of Denver and
about a foot in other parts of eastern Colorado and the Nebraska Panhandle. In
some areas, strong winds drifted the snow badly. Freezing rain fell south of the
snow belt as far south as northern New Mexico and the Texas Panhandle. East of the
snow belt, showers and thunderstorms dumped heavy rain from Texas to the Ohio
River Valley. The 4 to 10-inch totals caused flash flooding along the streams in
several States, especially Oklahoma, Missouri, and Illinois. Wide areas in the
Southwest received no rain or only light sprinkles.

TEMPERATURE: High pressure dominated the western half of the United States early
in the week and the eastern half of the Nation after midweek. The Highs brought
fair skies, mild days, and cool nights. Freezing temperatures occurred as far
south as central Arizona and northwestern New Mexico on Tuesday morning. On
Wednesday morning Alamosa, Colorado, registered 20° and North Platte, Nebraska,
32°. On Thursday, a cold front stretched from north to south across the northern
Great Plains. East of the front, brisk southerly winds carried gulf air northward
to the Great Lakes where Milwaukee, Wisconsin, registered 77° in the afternoon
after the mercury had dipped to 35 in the morning. West of the cold front, chilly
air swept southward across the northern Rocky Mountains and western Great Plains
holding afternoon maximums in the 50's and 60's. A severe weekend storm tumbled
the temperatures to below freezing over the northern Great Plains and much of the
central Plains. Las Vegas, New Mexico, registered 23° Sunday morning. By Monday
morning, the temperatures had dropped to zero at Alamosa, Colorado. Wyoming and
parts of neighboring States averaged 9° to 13° below normal. A wide band extending
from eastern Texas and the lower Mississippi River Valley to New England averaged
3 to 7 above normal. (Summary supplied by Environmental Data Service, ESSA.)

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE

ARMYWORM (Pseudaletia unipuncta) - KANSAS - Larvae heavy, moving from volunteer
into planted wheat. Portions of planted fields destroyed in areas of Clark County.
(Brooks). Occasional full-grown larva found on corn in Leavenworth, Jefferson, and
Johnson Counties. (Simpson). =

CORN LEAF APHID (Rhopalosiphum maidis) - WEST VIRGINIA - Colonies range 3-4 per
corn plant; all colonies dead in Jackson County. (Hacker). KANSAS - Small colonies
found in most wheat in Washington, Republic, Jewell, Mitchell, and Cloud Counties.

worth Counties. (Rummel, Oct. 3). Light in several panhandle counties. (Green).
KANSAS - Ranged 8-15 percent plants infested with 1-6 per leaf in sorghum in
Washington, Republic, Jewell, Mitchell, and Cloud Counties; greenbug in isolated
spots in every wheatfield examined. Ranged 1-25 per row foot in planted wheat and
1-35 per square foot in volunteer wheat. (Simpson). SOUTH DAKOTA - Averaged 2 per
row foot, up to 12 on some leaves, in all winter wheat sampled from eastern edge
to western edge of Brule County. No predators or parasites. Greenbugs may buildup
on south-central area wheat. (Jones).

SPOTTED ALFALFA APHID (Therioaphis maculata) - ARKANSAS - Ranged 1,000-1,500 per
100 sweeps in alfalfa in Washington County. Heaviest observed in State this year.
Extreme dry weather possible factor. Surveys negative in northeast areas where
moisture near normal. (Boyer).

CORN, SORGHUM, SUGARCANE

EUROPEAN CORN BORER (Ostrinia nubilalis) - MICHIGAN - Moths still in limited
numbers at blacklight Stations in Lenawee and Livingston Counties October l.
(Janes). SOUTH DAKOTA - Apparent increase in east-central area corn compared
to 1968. (Jones).

FALL ARMYWORM (Spodoptera frugiperda) - TEXAS - Larvae damaged grain sorghums
in Stonewall County. (Boring, Oct. 3). SOUTH DAKOTA - Infested 100 percent of
part of cornfield south of Kimball on Brule and Charles Mix county line. Mostly
last instars averaged 3 per stalk. (Jones).

SOUTHWESTERN CORN BORER (Diatraea grandiosella) - TEXAS - Heavy on corn in
several counties in northern panhandle. Found 80-95 percent of stalks in fields
infested; some lodging noted in Bailey County. (Clymer).

SMALL GRAINS

FALL ARMYWORM (Spodoptera frugiperda) - TEXAS - Heavy on small grains, grasses
and other crops throughout State. Larvae very heavy, averaged 6-8 per square foot
on oats near College Station, Brazos County. Found throughout High Plains;

appear to be decreasing. Heavy and widespread on Coastal Bermuda grass in Madison
County. Caused considerable small grain damage in many Rolling Plains counties
October 3. Larvae medium to heavy throughout central and north-central areas.
Spotted and heavy on small grain, grass, pastures, and ryegrass. Heavy in Falls
County small grain. Heavy and damaging small grain in Wichita, Wilbarger,
Throckmorton, Archer, Hall, Baylor, Motley, Stonewall, Cottle, Shackelford, and
Knox Counties. Controls applied. (Green et al.).

WHEAT STEM SAWFLY (Cephus cinctus) - NORTH DAKOTA - Survey of hard red spring
wheat stubble in 24 western counties complete. Cut stems ranged from 0-20
(averaged 0.5) percent in all counties surveyed. Decreased from 1.3 percent cut
stems in 1968. Fields with cut stems ranged zero in Dunn County to 100 percent
in Billings County. Forty-four percent of all fields sampled had cut stems.

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

CLOUDED PEACH BARK APHID (Pterochlorus persicae (Cholodkovsky) )

Economic Importance: The species is a serious pest of peach and related fruits
particularly in the Middle East. Persistent attacks have led to the death of the
trees in 10-15 years in Georgia and Armenia of the USSR. Severe infestations
have been reported in Afghanistan, Iraq, and Pakistan. Damage is caused by the
aphid sucking the sap from the bark and branches, As a result, fruit falls pre-
maturely and trees become weakened, In extreme cases, no fruit is produced and
growth is retarded. The large amount of honeydew, accumulating on the trees:
gives them a smothered appearance because of the sooty molds which grow on the
honeydew. Aphids, by the thousands, may obscure areas of the branches,

Distribution: Afghanistan, Cyprus, Egypt, Iran, Iraq, Israel, Lebanon, Pakistan,
Syria, Turkey, and USSR (Armenia, Azerbaidzhan, Crimea, Georgia, Murgab,
Turkestan, and Uzbekistan). Generally distributed in southern Europe to central
Asia.

Hosts: Almond, apple, apricot, cherry, citrus, peach, nectarines, pear, plun,
and quince,

General Distribution of Pterochlorus persicae (Cholodkovsky)

Life History and Habits: Under conditions in West Pakistan, the biology is as
follows: Reproduction may be parthenogenetic or sexual. Both viviparous and
Oviparous females occur. In Israel, males were not found (Bodenheimer 1957),

but they have been recorded elsewhere. Oviposition occurs in December and Janu-
ary in the Northwest Frontier Province of: Pakistan. Eggs, deposited in clusters
on the stems and branches, average over 350 per female. They are not in definite
rows but are scattered in the cluster. The species overwinters in the egg stage
and hatching begins in March, Immatures thrust their stylets into the bark and
suck the sap. The stem mothers produce about 30 living nymphs each, In the
spring, four generations of apterous viviparous females occur, each lasting. 25-30
days. The multiplication rate is greatly reduced from July through September.

Homoptera: Aphididae (Lachninae) No. 183 of Series

— 509) —

- 810 -

During these months five generations occur which average 12-15 days each. At
altitudes above 6,000 feet, the species reproduces rapidly even in the summer
months. Some alate viviparous females also occur from May through October. The
sexuales appear from early October to early December. Although the aphids are
active throughout most of the year in West Pakistan, they are most injurious in
spring and autumn, but in Israel they reach their lowest level in the fall. The
clouded peach bark aphid rarely seems to use its wings to fly. When the insect
is disturbed, it usually hops away by using its extremely long hind legs.

Description: ADULT - Alate viviparous female - Length 3.50-4.40 mm., hind leg
5.35 mm., and wing expanse 9.20 mm. Head about as broad as long, eyes black;
antennae short and black. Abdomen somewhat oval, not as broad as long as in
apterous viviparous female. Cornicles smaller than those of apterous female and
covered with scattered hairs on the tubercles. Legs reddish brown, Rostrum
large, extending almost beyond the cornicles. Wings rather slender with deeply
pigmented black areas. Apterous viviparous female - Length 4,48 mm. and hind
legs 5.35 mm. Color mainly a variegated black and white. Head black and eyes
very dark brown; antennae short. One white spot near middle of posterior edge.
Abdomen ovate and thickest around the cornicles which are large, black, truncated
on hairy cones. Numerous black spots in rows on dorsal side of body. Ventral
surface silvery white. Legs shining orange or reddish brown, extremely long.
Rostrum reaching 6th segment of abdomen. Apterous oviparous female - Quite simi-
lar to apterous viviparous female in external anatomy. Few secondary sexual
characters present. Male - Length of body 2,85-3.5 mm., wing expanse 9.13 mm,
Similar to alate viviparous female but smaller in size, with rather long antennae
(1.65 mm.) and with many more sensoria. Well developed genitalia.

WEATHER OF THE WEEK ENDING OCTOBER 27

HIGHLIGHTS: A cold wave brought record-breaking low temperatures to many north-
eastern localities on Thursday. Wet snow or cold rain fell from North Dakota to
New England. Parts of northern New England received unusually heavy snow. Heavy
rains delayed farm work in the Texas High Plains.

PRECIPITATION: Precipitation early in the week included light rains in the Far
Northwest, Snow in the lee of the Great Lakes and in New England, some heavy
thundershowers in the Southeast. A Pacific storm off the Washington coast
brought light rains to the Far Northwest. Northerly winds blowing across the
Great Lakes picked up moisture and deposited it as snow in New York and New
England. Montpelier, Vermont, received 7 inches of snow Wednesday forenoon.
Rochester, Vermont, received 1 foot of snow on Wednesday and even greater amounts
in the mountains. This was one of the heaviest October snows of record in New
England. Heavy rains fell at midweek in the southern portions of Arizona and New
Mexico and the nearby part of Texas. Over 3 inches of rain fell in the Lubbock,
Texas, area. Additional rain later in the week brought the Lubbock total to more
nearly 6 inches. Snow fell at the higher elevations in the southern Rockies
reaching a depth of 2 inches at Las Vegas, New Mexico, Wednesday forenoon. Week-—
end precipitation included more rain in Texas, the Florida Peninsula, and the

Northeast. A large area from California to South Dakota received no rain or only
light sprinkles.

TEMPERATURE: Unseasonally warm weather prevailed from southern New England to
the Gulf of Mexico early in the week. Boston, Massachusetts, registered 79 and
Baltimore, Maryland, 87 , on Monday. Cold northerly winds brought polar air
across the Great Lakes and pushed the freezing line steadily southward. By
Thursday morning, temperatures in the 20's, or lower, were common from the
Dakotas to New England and as far south as the Ohio River. Lexington, Kentucky,
registered 28 Thursday morning. In much of the Northeast, the cold temperatures
on Thursday morning were the lowest of record for so early in the season.
Warming occurred in the West in the first half of the week. Billings, Montana,
warmed to 73 Thursday afternoon before a cold front dropped the temperatures’
sharply. Parts of Montana remained below freezing from Friday morning to the end
of the week. Milder weather returned to the East over the weekend. Although
parts of the West were much warmer than the previous week, temperatures over most
Western States averaged below normal. Much of the Northeast averaged 3° to 9°
colder than normal. Above-normal weekly mean temperatures occurred along the
Gulf of Mexico. (Summary supplied by Environmental Data Service, ESSA.)

INSECTS NOT KNOWN TO OCCUR IN THE UNITED STATES

LARGE FLAX FLEA BEETLE (Aphthona euphorbiae (Schrank) )

Economic Importance: This chrysomelid beetle, one of the major pests of flax in
Europe, often causes sufficient damage to require replanting. Adults feed on the
tender parts of the plant above ground, leaving scalloped edges or holes in the
leaves. Overwintered adults may enter cracks in the ground to feed on seedlings
and cotyledons often killing them. New adults feed on shoot tips, blossoms, and
seed clusters, whereas larvae feed on the parts below the ground. The latter
gnaw Shallow grooves on the tap root or tunnel through the lateral roots.

Distribution: Belgium, Bulgaria, Cyprus, France, Germany, Great Britain, Hungary,
Italy, Libya, Netherlands, Poland, Rumania, Sweden, Syria, and USSR (European
portion and far eastern areas).

Hosts: Beets, Canada thistle, Euphorbiaceae, flax (Linum usitatissimum and Linum
Spp.), plum, and mustards. The species is polyphagous, but appears to reach
sexual maturity only on flax.

General Distribution of Aphthona euphorbiae (Schrank) )

Life History and Habits: Adults overwinter under brush or leaves at the edges of
forests. In northern Europe they usually emerge in May; in Italy, in April; and
in the Ukraine in early March or May. After feeding on the seedlings of various
plants, the overwintered adults shift to flax when this host germinates., Mating
and egg laying take place shortly thereafter. The female lays a few eggs on or
near the flax roots, and averages 300 eggs over a 2-week period. Eggs hatch in
10-22 days or less depending on the weather. Larvae feed on the roots for 26-30
days. Pupation occurs in a small cell built in the soil. Adults emerge about 9
days later at the end of June or the first half of July. They feed until August
or September or until the flax is harvested, whereupon they enter hibernation,
There is only one generation a year, Although this pest thrives under warn,
moist conditions, it can withstand low temperatures if the humidity is high, and
high temperatures if the humidity is low,

WEATHER BUREAU'S 30-DAY OUTLOOK
NOVEMBER 1969

The Weather Bureau's 30-day outlook for November is for temperatures to average
below seasonal normals east of the Rockies except for near normal in New England
and near to above normal over the Florida Peninsula. Above normal temperatures
are indicated for West Coast States while near normal values are expected in
unspecified areas. Precipitation is expected to exceed normal over the Atlantic
Coast States, the Midwest, and western portions of the central and southern
Plains. Subnormal precipitation is indicated west of the Divide except for near
normal totals in eastern portions of the central and southern plateau region

and along the central Pacific coast.

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 NOVEMBER 3

HIGHLIGHTS: This was the 4th consecutive cold week over mid-America. Rainfall
ranged widely from widely scattered light sprinkles in the Southwest to over 10

inches in the Florida Keys. Several inches of snow fell in the northern and
central Rockies.

PRECIPITATION: Early in the week, a large mound of arctic air covered the eastern
two-thirds of the Nation. Centered over the central Great Plains, it extended from
the Great Basin to the Atlantic Ocean and from Hudson Bay to the southern Great
Plains. This high pressure mass of polar air brought clear skies to much of the
Nation. However, as the cold air elbowed its way into Texas on Monday it nudged
aloft the warm moist air that lay over the southern Great Plains causing rains

and setting off thunderstorms. Locally heavy amounts of rain fell in the Rio
Grande Valley with several inches falling in the Laredo vicinity accompanied by
winds gusting to 68 m.p.h. Other thunderstorms occurred in the Florida Peninsula.
Key West received almost 5 inches of rain in 18 hours. Light precipitation also
occurred in the Far Northwest, rain along the coast and in the valleys and snow

in the mountians. Ten inches of snow fell at Bozeman, Montana, on Tuesday. Cold
air picked up moisture as it crossed the relatively warm waters of the Great

Lakes and caused light snow flurries from the lee shores of the Lakes to the
foothills of the nearby Appalachians. Weather of the week continued on page 830.

CHANGE IN SCIENTIFIC NAME

A Name Change in Dermestidae

i i i 1 is now to be known as
The dermestid known since 1954 as Trogoderma parabile Bea :
Trogoderma variabile Ballion, described in 1878. The change, first appearing in
M. Mroczkowski'’s 1968 catalog of the Dermestidae of the world (Polska Akad.
Nauk, Inst. Zool. 26(3):1-191), was confirmed by Dr. R.S. Beal, Jr.

Trogoderma variabile is a relatively common dermestid in stored products and
insect collections. Its distribution is rapidly becoming widespread through
commerce.

Weather of the week continued from page 824.

At midweek, a storm brought snow to the central Rocky Mountains and the nearby
western Great Plains. By Thursday snow had whitened most of Colorado, eastern
Wyoming, much of the Nebraska Panhandle and western Kansas, accumulating to
several inches over parts of those areas. Snow continued to fall along the
western edge of a wide rain area that extended from the eastern Dakotas to
eastern Texas. Amounts on Wednesday and Thursday ranged from less than 0.1

inch along the Red River of the North to over 2 inches at numerous localities

in eastern Texas. The weekend brought rains to wide areas from the Rocky Mountains
to the Atlantic coast. Gale winds accompanied the torrential rains along portions
of the Atlantic coast. The heaviest rains fell in Florida bringing weekly totals
to over 11 inches along the east coast and in the Keys. Jacksonville received
5.47 inches, over 3 times the November normal, in 24 hours ending at 7 a.m. on
Saturday. Over 7 inches fell at Myrtle Beach, South Carolina, in 6 hours late
Saturday evening. The storm weakened somewhat as it moved northward along the
coast but produced substantial moisture along the New England coast Monday,
November 3.

TEMPERATURE: The mountain of arctic air intensified the autumn chill over the
eastern two-thirds of the country. By Tuesday morning, the temperatures had
tumbled to the 30's as far south as Arkansas and Tennessee. The warmest areas
included the Far Southwest and the Florida Peninsula where afternoon temperatures
climbed into the 80's and the gulf where maximums reached the 70's. Some weekend
warming occurred in the Atlantic Coastal States. Weekly average temperatures were
above normal only in the Far West and from the middle Atlantic coast to Mobile,
Alabama. Most of the central and southern Great Plains averaged 6 to 12° colder
than normal. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-NOVEMBER TO MID-DECEMBER

The Weather Bureau's 30-day outlook for mid-November to mid-December is for
temperatures to average below seasonal normals over the eastern two-thirds of
the Nation except for near to above normal in the Northeast. Above normal
temperatures are expected west of the Divide while near normal temperatures
are indicated in unspecified areas. Precipitation is expected to exceed normal
over the Ohio Valley and the Northeast as well as in California. Subnormal
totals are indicated over the northern intermountain region as well as the
Mississippi Valley and eastern portions of the Great Plains. Elsewhere near
normal precipitation 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 NOVEMBER 17

HIGHLIGHTS: Wintry weather occurred over much of the Nation during at least part
of the week. Some warming occurred in the southern Great Plains over the weekend,
Heavy snow fell in the lee of the Great Lakes.

PRECIPITATION: High pressure and clear skies prevailed over most of the United
States early in the week, The main exceptions included the light snow flurries

in the northern Rockies and the more generous Showers in New England. Precipitation
continued in parts of the Northeast for 13 consecutive days. In some locations,
this was the most consecutive days with rain of record. The amounts of rain
received threatened to exceed previous November totals at some localities also.
About midweek, a blast of wintry weather moved into the northern and central

Rocky Mountains. Heavy snow driven by strong winds closed mountain highways in
Colorado. Snow squalls occurred in the lee of the Great Lakes over the weekend.
Snow accumulated to about 10 inches in the La Porte and South Bend, Indiana,
areas, to about 14 inches at Holland and 12 inches at Hancock in Michigan, and

6 to 10 inches in New York near Lake Erie, Niagara Falls, New York, received 6
inches in 1 hour Saturday evening. The central and southern Appalachians saw the
first major snowstorm of the season. Up to about 5 inches fell in the mountains

of Kentucky, North Carolina, and Virginia and up to 11 inches in West Virginia.
Meanwhile, another winter storm moved into the northern Rockies. By Sunday evening
9 inches of snow had accumulated at West Yellowstone, Montana. Except for locally
heavier totals, the weekly amounts over the western half of the United States

were generally less than 0.5 inch. weather of the week continued on page 848.

Weather of the week continued from page 844.

TEMPERATURE: High pressure, fine weather, and near-normal temperatures extended
almost from coast to coast early in the week. Afternoon temperatures reached the
40's and 50's across the North and the 70's and 80's across the South. Consider-
able fog lay over the Central and East. About midweek, fresh, cool, dry air pushed
the fog and pollution from the Central and East and a change in circulation brought
dry arctic air into Montana, By Friday, the leading edge of the cold air had
reached the Gulf of Mexico and by Saturday morning the temperatures in northern
Florida had tumbled into the 20's. The arctic air brought a hard freeze to much

of the Deep South. In areas from Alabama to North Carolina, such cold temperatures
had never previously occurred so early in the season, Mild weather lingered only
along the southern Atlantic seaboard, Saturday was sunny but cold over most of

the Nation, Blustery winds sharpened the bite of the cold. Southerly winds warmed
the southern Great Plains, Oklahoma City, Oklahoma, warmed to 70° on Saturday; the
highest temperature on Friday was 42°, Additional warming occurred in southern
Texas on Sunday. Temperatures averaged above normal over the western half of the
Nation and below normal over the eastern half. Large areas in the West averaged

4° to 7° warmer than normal, Parts of the East averaged 6° to 9° colder than
normal, (Summary supplied by Environmental Data Service, ESSA).

Forage Crop Insects in Massachusetts in 1969
D.E. Miller and F.R. Shaw

Population studies of the insect pests of forage crops, especially alfalfa, were
conducted during the 1969 season.

Collections were made at weekly intervals in Hampshire County and biweekly in
Berkshire County. The remainder of the counties of the State were sampled only
once, at the time high alfalfa weevil (Hypera postica) populations were expected
to be present. Fields were sampled by taking 100 sweeps with a 15-inch net. The
insects were identified in the laboratory. A summary of the population studies is
presented in Table l.

Compared with the 1968 collections, some differences in the 1969 insect popula-
tions were obvious. Early in 1968, the authors noted a few alfalfa leaves damaged
by larvae of a leaf miner fly. By fall, damage had increased. Leaf miner flies
became the most abundant insects present in 1969. Pea aphid (Acyrthosiphon pisum)
was the second most abundant species in Hampshire County, but alfalfa weevil was
second in abundance in Berkshire County. .The release of more parasitic species

in Hampshire County may account for the lower alfalfa weevil population in that
county. Plant bugs decreased from 11.9 percent in 1968 to 4.5 percent in
Hampshire County and 4.2 percent in Berkshire County. Similarly meadow spittlebug
(Philaenus spumarius) decreased from 11.48 percent to 3.5 and 1.2 percent in these
two counties, respectively. Leafhopper populations were Similar both years,
Beneficial insects, aS a group, were Somewhat less abundant in 1969 than in 1968.

Alfalfa weevil larvae were collected in Berkshire, Franklin, Hampshire, and
Plymouth Counties from May 13 through June 24 to obtain more information on the
percent of parasitism. Third or fourth-instar larvae were vialed singly and held
until the adult weevil or the parasites emerged. The data, summarized in Table 2,
substantiate the increase in parasitism by Bathyplectes curculionis (an ichneumon
wasp) and the decrease in parasitism by Tetrastichus incertus (a eulophid wasp)
observed during the period 1965 through 8.

Much time was spent investigating the leaf miner flies infesting alfalfa. Infested
alfalfa was brought to the laboratory and the larvae reared to adults. They were
determined as Agromyza sp. and Liriomyza sp. by K.A. Spencer. The extent of damage
to alfalfa by these leaf miners is presented in Table 3.

WEATHER OF THE WEEK ENDING NOVEMBER 24

HIGHLIGHTS: Weather events in the past week have removed any doubt that winter
Over most of the country has begun. In parts of eastern United States it was the
sixth consecutive cold week and the coldest since March.

PRECIPITATION: A powerful cold front stretched across mid-America from north to
South early in the week. Southerly winds brought mild, moist air northward ahead
of the front. Northerly winds pushed rigid arctic air southward west of the front.
Cloudinesss increased and rain fell ahead of the eastward-moving front. Some
thunderstorms occurred in the warm, moist air. By Tuesday, rain covered a belt
about 300 miles wide and extending from the Great Lakes to the Gulf of Mexico.
As the front approached, snow became mixed with rain in the northern and central
sections. Snow fell in the cold air after the frontal passage followed by
clearing skies. Cold air picked up moisture as it crossed the Great Lakes and
deposited heavy snow on the lee side of the lakes. Light snow flurries occurred
from the northern Rockies to the Great Lakes and in the Appalachians late in the
week. Other precipitation included rain early in the week along the Washington
and northern Oregon coast and several inches of snow in the Cascade and Olympic
Mountains. The weekend was mostly sunny.

TEMPERATURES: The strong cold front that stretched across the Nation early in
the week Separated two air masses which differed widely. To the east lay warm
moist gulf air. Cold, dry arctic air covered the northern and central Great Plains
west of the front. At noon Monday, Topeka, Kansas, registered 70° and Concordia,
about 100 miles west of Topeka , registered 37°, As the front moved eastward,
temperatures tumbled 10-15 within an hour. By Wednesday noon, only the eastern
seaboard lay in the warm air. After the front had moved to the Atlantic, sub-
freezing temperatures occurred as far south as the gulf coast. Temperatures from
Lake Charles to New Orleans, Louisiana, dropped from near 80° on Tuesday to below
freezing by Friday morning. Zero temperatures occurred in the Red River of the
North Valley late in the week and thin ice formed at some places in the northern-
most Great Lakes. Subzero temperatures also occurred in the central Rocky
Mountains. As a huge high followed the front it brought clearing skies and
warming occurred west of its center. Sydney, Nebraska, which had been no warmer
than 28° on Tuesday, warmed to 60° by Friday afternoon. The warming trend spread
eastward and by Sunday, sunny, pleasant weather covered most of the Nation.

TURF, PASTURES, RANGELAND

BILLBUGS (Sphenophorus spp.) - MARYLAND - Seventy-five specimens of S. sayi,

S. parvulus (bluegrass billbug), and S. venatus vestitus emerged from outer
‘exposed rolls of two trays of Merion bluegrass sod. bach tray contained 55 rolls
(500 square feet) of stacked commercially grown sod. Emergence occurred near
Poolesville, Montgomery County, October 9-11, 1969, following exposure to surface
irrigation and sunlight at temperatures in high 70's. Specimens were determined
by R.E. Warner as follows: 7 S. parvulus, 12 §. venatus vestitus, and 56 §S.

WEATHER OF THE WEEK ENDING DECEMBER 2

HIGHLIGHTS: Extensive sunny skies prevailed over most of the Nation last week.
Mild weather predominated over the northern Great Plains. Mild days and cool
nights were the rule over the East and Deep South.

PRECIPITATION: Wide areas from the Pacific Ocean to the Ohio River Valley
received no rain or only widely scattered light sprinkles last week. A Pacific
storm brought light rain to the Washington coast early in the week. Also early
in the week a low off the New England coast brought a blanket of snow to the
northern portions of Vermont, New Hampshire, and Maine. Light rain and drizzle
fell on several days along the gulf coast from southern Texas to Florida with
totals generally less than 0.20 inch except in southern Texas where generous
Showers dumped 2 to 4 inches at some locations. Two to 6 inches of snow fell in
the Trans-Pecos on Thursday. Light snow flurries fell from Minnesota to Michigan
shortly after midweek and several inches of snow fell over the weekend in western
New York along the lee shores of Lake Erie,

TEMPERATURE: Extensive high pressure areas produced mostly clear sunny weather
Over much of the Nation. Maximum temperatures ranged from the 30's and 40's over
the Northern States to the 70's and 80's across the South early in the week but
dropped about 10° by Thursday afternoon. Subfreezing temperatures occurred every
day as far south as the central Great Plains and by Thursday morning the freezing
line had plunged into the northern portions of Alabama and Georgia. Subzero
temperatures occurred on 1 or 2 nights in western Wyoming and spots in northern
Minnesota and northern New England. Temperatures averaged above normal in the
West and North Central and below normal in the East and South Central. Much of
the northern Great Plains averaged 6° to 12° above normal. It was the 7th

consecutive cold week in Pennsylvania. (Summary supplied by Environmental Data
Service, ESSA.)

WEATHER BUREAU'S 30-DAY OUTLOOK
DECEMBER 1969

The Weather Bureau's 30-day outlook for December is for temperatures to average
below seasonal normals in the eastern third of the Nation as well as the southern
Plains, California and northern and southern portions of the plateau region.
Above normal temperatures are indicated for the northern and central Plains while
near normal temperatures are in prospect in unspecified areas. Precipitation is
expected to exceed normal over the southern plateau, the southern Rockies and the
west gulf coast region. Subnormal totals are in prospect elsewhere west of the
Divide and also over the upper and middle Mississippi Valley, the Ohio Valley,

and the Middle and North Atlantic States. Elsewhere near normal precipitation
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.

COOPERATIVE ECONOMIC INSECT REPORT
ESTIMATED LOSSES AND PRODUCTION COST ATTRIBUTED TO
INSECTS AND RELATED ARTHROPODS - 1968
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 fourth 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 17 States. The
entomologists submitting the 1968 estimates are listed below.

WEATHER OF THE WEEK ENDING DECEMBER 8

HIGHLIGHTS: Winter continued in the East. It was the coldest week of the season
in New York and the 8th consecutive cold week in Pennsylvania. Heavy snow fell
in parts of the central Great Plains, the Great Lakes region, and the Northeast.

PRECIPITATION: Fair skies prevailed over most of the Nation early in the week

but midweek brought precipitation to about half of the States. Light rains fell
almost daily along the northern Pacific coast and in the nearby mountains snow
accumulated to 10 to 30 inches above 3,000 feet. Light widely scattered showers
occurred over much of the western half of the Nation but the weekly totals
generally did not exceed 0.25 inch. Wet snow fell above 5,000 feet in the

mountains in southern California and several inches fell east of Albuquerque,

New Mexico, on Thursday. Light snow fell in the northern and central Rocky
Mountains and western Great Plains at midweek with locally heavy accumulations of
up to 7 inches in northeastern Kansas and to 9 inches in northern Missouri. New
York received 2 to 8 inches of snow early in the week and up to 6 inches fell in
western Connecticut. Geauga County, Ohio, received 12 inches of snow on Wednesday
and a major storm dumped 6 to 12 inches on parts of Wisconsin and Michigan on
Sunday. Much of the Northeast received snow, sleet, freezing rain, or rain over the
weekend. On Monday night, December 8, Duluth, Minnesota, measured 21 inches. of snow
on the ground and it was still falling.

TEMPERATURE: Mild clear temperatures prevailed over the Great Plains early in

the week. Temperatures reached the 50's and 60's in Montana and North Dakota on
Monday, December 1. Cold weather lingered in the East. Frost occurred in northern
and central Florida on several days early in the week and at interior localities

in southern Florida on the Ist. At midweek, cold arctic air moved into the northern
Great Plains. Temperatures plunged to below zero in northern Minnesota, on

Thursday morning. By Friday, much of the Nation was in the grip of the cold air

and on Saturday afternoon, temperatures remained in the 40's and 50's in New

Mexico and in all of Texas except the extreme south. Subzero weather occurred in
the northern and central Rockies on Monday morning, December 8, when Alamosa,
Colorado, registered -8°. Southerly breezes brought some warming in the Deep

South on Sunday when afternoon temperatures reached the 50's as far north as the
Ohio River. Temperatures averaged below normal in the Far Northwest and from
eastern New Mexico to the Atlantic Ocean and northeastward to New England. Above-
normal temperatures predominated from Arizona to Lakes Superior and Michigan. Parts
of the northern Great Plains averaged 6 to 10° above normal in spite of the

extreme cold weather there. (Summary supplied by Environmental Data Service, ESSA.)

WEATHER BUREAU'S 30-DAY OUTLOOK
MID-DECEMBER 1969 TO MID-JANUARY 1970

The Weather Bureau's 30-day outlook for mid-December to mid-January is for
temperatures to average above seasonal normals over the western half of the
Nation and below normal over the eastern half with greatest departures in
Middle and South Atlantic States. Precipitation is expected to exceed normal in
the Northeast as well as over the central and north Pacific coast. Subnormal
amounts are indicated for the southern Plateau, and from the Rockies to the
Appalachians except for near normal totals in the southern Plateau, the gulf
coast, and Great Lakes regions. Elsewhere near normal precipitation is in
prospect.

Weather forecast given here is based on the official 30-day "Resume and Qutlook"
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 DECEMBER 15

HIGHLIGHTS: Winter storms brought rain accompanied by high winds to the Pacific
coast with snow above about 5,000 feet and heavy snow to parts of the Great Lakes
region and the Northeast.

PRECIPITATION: Several disturbances brought stormy weather to much of the Nation
Tast week. Precipitation fell in 40 States Tuesday forenoon. Light rain fell along
the Pacific coast, in the southern Great Plains, the lower Mississippi River
Valley, along the Gulf of Mexico from Texas to Florida, and in the Atlantic

Coast States. Snow fell from the interior sections of the Pacific States across
the Rockies to the upper Great Lakes. A number of tornadoes occurred in the
central Florida Peninsula on Wednesday forenoon. A storm off the Pacific coast
intensified after midweek. Winds gusting to more than 100 m.p.h. battered

WEATHER OF THE WEEK ENDING DECEMBER 22

HIGHLIGHTS: In the West, rains continued along the coast with snow at higher
elevations. The Northeast was cool, cloudy, and snowy. The Southeast was cool,
becoming rainy in the latter part of the week.

PRECIPITATION: Moderate to heavy rain fell along the northern and middle Pacific
coast and the nearby interior valleys with snow in the nearby mountains on most
days. Rains along the coast were accompanied by winds which in some areas gusted
to 50 m.p.h. or more. The snow depth left over 5 feet at Mount Baker Lodge,
Washington. Little precipitation occurred on the eastern slopes of the Rocky
Mountains and the western Great Plains. Strong winds raised clouds of dust in
local areas in eastern Colorado. Mostly light precipitation fell in the Great
Plains. Snow began early in the week in the Northeast with daily occurrences in
some areas. Totals ranged widely but some areas from Wisconsin and Indiana to
New England received 5 to 12 inches. Rain or drizzle occurred in the Southeast
mostly late in the week. Totals exceeded 1 inch from Louisiana to Georgia, but
were mostly less than 1 inch elsewhere in the Southeast.

TEMPERATURES: In general, clear skies and light temperatures prevailed from the
Great Basin to the Mississippi River. Much of the Great Basin averaged 9° to 12°
warmer than normal. This was the seventh consecutive mild week in Montana.
Temperatures turned sharply colder in the northeast where most days were cloudy.
Concord, New Hampshire, averaged 20° colder than the previous week. A large area
from the Ohio River to the mid-Atlantic coast averaged 6° to 10° cooler than
normal. Cool days and cool nights continued in the Southeast where clear skies
prevailed early in the week, followed by partly cloudy to cloudy weather.
