WEATHER OF THE WEEK ENDING AUGUST 12

Reprinted from Weekly Weather and Crop Bulletin supplied by
Environmental Data Service, NOAA.

HIGHLIGHTS: Rains fell across most of the Nation east of the
Rocky Mountains last week. Good rains fell over the Texas High
Plains for the second week. The critically dry Corn Belt area
received 1 inch or more of rain while some parts of north-central
and northwestern Ohio got only minimal 2 inches to over 7 inches,
San Antonio, Texas, reported 7.13 inches, Tulsa, Oklahoma got
3.12 inches for the week. Temperatures were below normal across
most of the Nation last week. The Great Lakes area and the
interior portions of California northward through Oregon and

into the Columbia River Basin in Washington were above normal

for the week.

PRECIPITATION: Widespread, heavy rains fell across eastern
Virginia, North Carolina, South Carolina, Georgia, Alabama, and
along the Florida Peninsula averaging from 2 inches to over 6
inches last week. Isolated heavy Showers were reported through-
out the Midwest with amounts of one inch or more common. Over

3 inches soaked the Louisville and Lexington, Kentucky, areas.
West-central Montana received 1 inch or more of rain with 2.63
inches reported at Havre. Little or no rain fell in the Far West.
Monday, rainfall was heavy near the southern Atlantic coast in
the south-central Plains, and on the southern Plateau. Between
one inch to 3 inches of rain fell throughout north-central

Texas, western Oklahoma, and south-central Kansas. Laverne,
Oklahoma, and Turon, Kansas, received almost 3 inches while
Abilene, Texas, Gage, Oklahoma, and Dodge City, Kansas, received
1 inch or more. Tuesday, an area of scattered thundershowers
extended from southern Texas into northwest Missouri-providing
the first rain for some areas in many weeks. Most Showers were
light and of little real help to the already parched land. The
heaviest activity was centered in north-central Texas. Wednesday,

SPECIAL INSECTS OF REGIONAL SIGNIFICANCE

ARMYWORM (Pseudaletia unipuncta) - TENNESSEE - Larvae present in
fields of Iate corn in scattered areas of State. Growers and
homeowners advised to check pastures and lawns regularly for
larvae from now until frost. (Gordon). KENTUCKY - Damaged corn
in Bath County; 70-80 percent of plants damaged at one location.
(Barnett). MICHIGAN - Controls applied to 400 acres of corn and
small grains in Alger County. (Norlin). OKLAHOMA - Two larvae
collected from cornfield in Trupin area, Beaver County. (Okla.
Ghon.s)-Sur...).

CORN EARWORM (Heliothis zea) -—- FLORIDA - Comprised 90 percent of
pests in supervised, scouted peanut fields totaling 900 acres in
southwest Alachua and Levy Counties; overall larval problem
rated "very mild."' Larvae attacked foliage and flowers. Only 195
percent of total acreage treated by July 31. (Fla. Coop. Sur.).
GEORGIA - Moth catches increased sharply in Spalding County
blacklight trap; from less’ than one per night to 50 per night. by
August 8. (Tippins). TENNESSEE - Larvae heavy in several fields
of late-planted corn in State. Larvae feeding as budworms,
control difficult. Only very few fields surveyed this period
expected to show significant yield reduction. (Gordon). NORTH
CAROLINA - Adults observed laying eggs on soybean blooms in
Sampson and Duplin Counties. Light trap catches showed moth
flight from corn underway. Larvae expected in 7 to 14 days on
soybeans. However, fields should be scouted as disease incidence
very high. (Hunt).

VIRGINIA - Survey of corn in mountainous counties in southwest
area Showed zero H. zea infestations in Montgomery, Botetourt,
Pulaski, Franklin, Wythe, and Giles Counties, 20 percent in
Roanoke County. Overall infestation 4 percent in these counties.
(Allen). Damage much lighter than usual this season on Eastern
Shore. Sweet corn harvested in Painter area showed about 33 per-
cent of ears damaged this season in contrast to near 100 percent
normally expected for this time of year. (Hofmaster). MARYLAND -
Moth catches in blacklight traps increased, particularly in
middle Eastern Shore area. Egg counts on corn silks also increased
i Most, Seetions..(U. Md..5° Ent. Dept. ).

INDIANA - Single H. zea moths taken in blacklight traps in
Lawrence County July 25, Tippecanoe County July 30, and Randolph
County July 31. (Barlow). ILLINOIS - Larval feeding light on ear
Paps ot cory i St. Claixc County. (ill..ins. Rpt.) ... ARKANSAS. =
Only occasional larvae found in grain sorghum surveyed in Ashley,
Jefferson, Lincoln, and Washington Counties. (Boyer). UTAH -
Blacklight trap catches decreased at Salt Lake City, Salt Lake
County, and Logan, Cache County, during past 3 weeks. aac es
Stephens). Larvae light in Utah County corn. (Duncan).

WASHINGTON - Caused 13 percent damage to test plot of corn at
Othello, Franklin County. (Antonelli).

- 645 -

CORN LEAF APHID (Rhopalosiphum maidis) - NEW MEXICO - Ranged

10-50 per whorl on corn and sorghum in Eddy and Chaves Counties.
(N.M. Coop. Rpt.). OKLAHOMA - Some scattered heavy infestations
still present in sorghum in Panhandle counties but no problems
expected as populations should decline rapidly in most fields as
plants mature and parasites become active. Moderate in Greer
County. (Okiaj Coop... ‘sur.).. NORTH, DAKOTA, — Antested Silage corn

in Morton, Sioux, Grant, and Bowman Counties; 50-100 percent of
plants infested with up to several thousand R. maidis per tassel.
Some honeydew evident. Averaged 250 per plant on Sudan grass in
Morton County. Colonies observed on pigeon grass in Bowman County.
(Brandvik). WISCONSIN - Heavy in many cornfields. Up to 30 percent
of plants in northwest area noted with colonies of 500 or more.
Similar infestations common throughout central sands area.
Populations much lighter elsewhere; nearly every area noted with
fields having 500 or more colonies on 10 percent of plants. This
is recommended treatment level. (Wis. Ins. Sur.). MARYLAND - Heavy
on 5 acres of sweet corn near Temple Hills, Prince Georges County.
Generally light statewide. (U. Md., Ent. Dept.).

GREENBUG (Schizaphis graminum) - TEXAS - Light to moderate damage
observed in grain sorghum in Jones County. Heavy infestations
damaged irrigated sorghum in Knox County; moderate infestations
reported in Wilbarger County. Populations reported as near peak
in High Plains. Beneficial insects increasing throughout area.
(Boring et al.). OKLAHOMA - Ranged light (25 per plant) to heavy
(3,000 per plant) in sorghum in Beaver, Texas, and Cimarron
Counties. Continued to increase Slowly in most areas but parasite
activity beginning. Scattered fields treating some for second time.
Greenbug light in Greer County. (Okla. Coop. Sur.). ARKANSAS -
Light in Lincoln County sorghum. This is a new county record.
None found in other counties surveyed. (Boyer).

NEBRASKA - Greenbug remained stable or increased; parasitism by
Lysiphlebus sp. (a braconid wasp) still light, less than 4 per-
cent over most of State. Many sorghum fields treated. Greenbug
ranged O-5,000 in 361 Clay County sorghum fields, Parasitism by
Lysiphlebus sp. averaged 3 percent compared with 58 percent same
time in 1973. (Gary, Keith). Greenbug heavy in 2 Lancaster County
sorghum fields; 2,000+ per plant with 2-3 lower leaves dead or
dying. (Roselle, Koinzan). Damage mostly light to moderate in 7

fields surveyed in Lincoln, Perkins, Chase, and Hitchcock Counties.

One Perkins County field had moderate to heavy damage with lower
two leaves killed. (Campbell). IOWA - Heavy on 20 acres of Sac
County grain sorghum. (DeWitt).

POTATO LEAFHOPPE” <Empoasca fabae) - WISCONSIN - Still serious
problem on untreated potatoes and beans. Seldom exceed one per
Sweep on commercial crops in southern and central districts.
Ranged 1-2 per sweep on soybeans throughout most of State. One
field each on Sauk, Dane, and Rock Counties noted with 4+ per
sweep. Nymphs noted on plants in all cases, problem will become
more severe aS nymphs mature. Ranged 3-4 per sweep on alfalfa
throughout State except in very few dry, sandy fields in southern
counties where up to 55 per sweep noted. Infestations about one
per sweep in Bayfield County. (Wis. Ins. Sur.). MICHIGAN -
Threatening populations appeared on Clinton County alfalfa;
continued threat on field beans in county. (Lasher, Ruppel).
INDIANA - Populations in alfalfa decreased in many fields due to

- 646 -

extreme drought conditions in southern districts; few immatures
present. Treatments still necessary in 5 of 30 fields examined.
(Frazee, Edwards). Adults and immatures still problem in northern
counties. (Edwards). OHIO - Potato leafhopper adults and nymphs
generally at economic or near economic levels, yellowed and
stunted alfalfa common statewide. Ranged 9-l1l per sweep in one
Fairfield County field. (Fox). PENNSYLVANIA - Adults per sweep by
county: Mercer, 0.8 in 10 to 15-inch aAltalta, ‘controls appilaed,
no damage reported; Lycoming, 0.5 in 6 to 8-inch al faire Si]
controls applied. (Palisin, Proseus).

SPOTTED ALFALFA APHID (Therioaphis maculata) - WISCONSIN - Up to
60 per sweep noted in central district alfalfa. Heaviest popula-
tions found on sandy soils. (Wis. Ins. Sur.). INDIANA - Averaged
20 per sweep of 14-inch alfalfa in one of few fields not yet
harvested in Vermillion County. (Meyer).

TOBACCO BUDWORMS (Manduca spp.) - TENNESSEE - Larvae infested 3
of 10 tobacco fields checked; one of 3 infested fields with
larvae at or above control levels. (Gregory). Topping of tobacco
well underway in State; few fields being cut. (Gordon).

CORN, SORGHUM, SUGARCANE
EUROPEAN CORN BORER (Ostrinia nubilalis) - MINNESOTA - First

eeneration nearing end of cycle, few adults emerged in east-central
and west-central districts. Trace moth counts noted in alfalfa as

WoMnas corm. Pereent infested corn plants by district: East—
central 3.7, southwest 18, west-central 6. Borers per 100 plants
by district: Hast-central 1.3, southwest 6, west-central 10.

(Minn. Pest Rpt.). WISCONSIN - Moth activity increased as night-
time temperatures increased. Warmer nightly temperatures should
induce more moth activity but blacklight trap catches expected to
be erratic through September depending on nighttime temperatures.
Fields of late sweet corn can develop problems from second genera-
tion larvae but now appears very unlikely significant problems
will develop in field corn. Most borers not yet pupated will
diapause until spring 1975. Second moth flight will be comprised
of only those in pupal stage to date; this flight expected to be
active until end of canning season. Egg masses noted in some
Walworth County fields. Most larvae in fourth and fifth instars

in Chippewa, Dunn, St. Croix, Pierce, and Pepin Counties. Many
second and third instars noted in one field, no pupae. Pupal
populations equal or exceed larvae in central sands area. Probably
most intense Second-generation activity will be in central sands
area on beans, potatoes, and sweet corn. (Wis. Ins. Sur.).

ILLINOIS - Feeding by second-generation European corn borer larvae
in corn widespread throughout southern half of State. (Ill. Ins.
Rpt.). MISSOURI - Infestations light to moderate on corn in north-
east area. Egg masses ranged 2-23 per 100 plants and 8-58 percent
of plants infested with first and second-instar larvae. (Munson).
MICHIGAN - Threatening in scattered cornfields from Monroe to
Mason Counties. (Nevel et al.). Adult activity increased.

Larvae active in sweet corn, peppers, and snap beans. Spray
schedules should be adjusted according to crop. (Cress).

KENTUCKY - Continued to damage corn, especially in Madison County.
(Barnett). MARYLAND - Moth catches in light traps declined, but
egg mass counts on corn remained heavy in most sections. (U. Md.,
Ent. Dept.). DELAWARE - Moths averaged 30 per night in blacklight
traps in western Sussex County. (Burbutis).

- 647 -

SOUTHWESTERN CORN BORER (Diatraea grandiosella) - OKLAHOMA -
Second-generation larvae present in most cornfields in Beaver,
Texas. and Cimarron Counties; infestations light in most fields.
One late-planted Texas County field noted with 17 percent of
emerging tassels infested. (Okla. Coop. Sur.). ARIZONA - Damaged
untreated, late-planted sorghum in Marana area of Pima County.
(Ariz, (ECOOps . SUAI))),.

FALL ARMYWORM (Spodoptera frugiperda) - MISSISSIPPI - Continued

to infest pretassel corn throughout State as budworms. Hardest

hit areas in southern area where 90-100 percent of plants infested.
In central and northern areas, 30-60 percent of plants in fields
of young corn and sorghum infested. (Robinson). ARKANSAS -
Continued light in late sorghum. One field treated in Ashley
County; infestation very light, treatment probably not justified.
(Boyer).

CORN ROOTWORMS (Diabrotica spp.) - MISSOURI - Adults active in
northeast area. D. virgifera (western corn rootworm) ranged 2-3
per plant and D. longicornis (northern corn rootworm) 0-9.
(Munson). IOWA - Damage to corn silks by Diabrotica spp.
increased in central part of State. Treatments applied in Cedar,
Franklin, and Sac Counties where beetles ranged 10-15 per plant
im various fields: (DeWitt). ILLINOIS = Adults of D. virgiftera and
D. longicornis ranged 0-9 per corn plant in Logan, Woodford, and
Peoria Counties. (I1l. Ins. Rpt.). MICHIGAN - Adults caused much
damage to green silks of field corn which had been treated at
planting time in Eaton County. D. virgifera and D. longicornis
adults generally abundant in corn-growing areas of State. (Ruppel
et al.ps

WISCONSIN - Many Diabrotica spp. larvae and pupae still in soil in
Dane and Crawford Counties. Adult emergence still heavy at
Arlington, Columbia County. Cooler temperatures slowed emergence
and oviposition will last longer than normal. Adult populations
highly variable. Heavier in corn in which silks just beginning to
brown; few adults found in fields with little or no silking.
Average population in well-silked fields less than one per plant,
2-6 per plant noted, in Some, fields: Upto Lo per_plantenoted, in one
Dane County field. Heavy lodging (50 percent) noted in margins of
one Walworth County Puedd,. Average of 12 percent lodging noted in
Crawford County field. Due to many late fields of corn, heavy
populations could appear in some fields and cause much damage by
cutting si tkst Wis. Vins. Sur...) -

MINNESOTA - Preliminary results of adult Diabrotica spp. survey
showed generally light populations, but Occasional fields have
heavy counts and much lodging. Beetles averaged 1.03 per plant in
2 east-central district counties; lodging 90+ percent in several
fields. In 5 McLeod County fields surveyed no beetles found. Most
beetles still found in leaf axils but some feeding on silks.
(Minn. Pest Rpt.). SOUTH DAKOTA - Adults of D. virgifera and D.
longicornis found in most cornfields. Ratio of males to females
higher than normally expected in several infested fields in
Brookings, Lake, and Lincoln Counties. Lowest ratio of males to
females was 7:1. (Walgenbach, Kantack).

- 648 -

WESTERN CORN ROOTWORM (Diabrotica virgifera) - UTAH - Adults
heavy in many cornfields in Cache and Boxelder Counties. (Roberts
et al.). OKLAHOMA - Adults still light in most cornfields in
Panhandle counties. Some D. undecimpunctata howardi (southern

NEBRASKA - Averaged 0.86 per plant in 340 Clay County fields.
Ranged 2-8 per plant in 5 cornfields per county in Lancown.,
-Perkins, Chase, Dundy, and Hitchcock Counties. Overall averages
ranged 3-4 per plant. (Keith). MICHIGAN - Adults collected from
corn near Perry, Shiawassee County, and near Milford, Oakland

Lubbock and Amarillo. Some infestations in corn treated in Lamb
County. Scattered infestations needing treatment reported from
Amarillo area. (Boring et al.). OKLAHOMA - Still heavy in
untreated cornfields in Texas County; populations not increasing
due to cool, wet weather past 14 days. Generally light in Beaver
and, Cimarron (Counties... (Okla. .Coop....Sur .).

SMALL GRAINS

HESSIAN FLY (Mayetiola destructor) - ILLINOIS - Summer survey of
wheat stubble indicated very light population, same as past
several years. Heaviest count, 10 puparia per 100 tillers, found

Mason 1, Jersey 10, Clark 2, Saline 2, Wayne 2; zero in Morgan,
Effingham, Shelby, and Clinton Counties. (I11l. Ins. Rpt.).

TURF, PASTURES, RANGELAND

CHINCH BUG (Blissus leucopterus leucopterus) - MISSISSIPPI -
Caused very minor problems in turf, pastures, and rangeland this
Season compared with 1973. Possibly due to more frequent rains
in southern area. (Robinson).

GRASSHOPPERS - KENTUCKY - Adults and nymphs of various species

averaged 150 per 100 sweeps in roadside grasses, mostly fescue, in
Nicholas County. (Barnett).

- 649 -

light to moderate damage to alfalfa in several areas checked;
generally, damage not severe enough to warrant control. (Gall).
NEW YORK - Mines observed in Otsego County on second and third-
cutting alfalfa August 8 mostly in full-blotch stage; many empty
mines indicate high percent second-generation pupation. Plants

counts and foliage damage began to increase on soybeans on

Eastern Shore. (U. Md., Ent. Dept.). VIRGINIA - Larvae and new
adults moderate in few fields in Northumberland County. Control
not yet warranted as counts not high enough and predators are
heavy. (Allen). INDIANA - Heavy populations reported in

scattered fields throughout State south of U.S. Interstate Highway
70; treatment probably necessary in some instances. (Edwards).

BEAN LEAF BEETLE (Cerotoma trifurcata) - MINNESOTA - Found in
southwest district fields. Although infestations averaged less
than one percent, some fields appear heavily damaged with many
holes in leaves. Populations usually heavier in field edges
giving false impression of extent of damage. (Minn. Pest Rpt.).
OHIO - Complex of this species and Diabrotica undecimpunctata
howardi (southern corn rootworm) can be found in soybeans state-
wide; much more prevalent than for past 2 years. Beetles ranged

Weather continued from page 644,

a cold front caused widely scattered thundershowers in the

northern Plateau and Rockies. Elsewhere, heavy rains during the

past several days caused destructive flooding along the Lumber

River in the southern portion of North Carolina. Thursday,

scattered thunderstorms, rain, and hail along with a few

tornadoes, were reported from the Atlantic coast across the

Rockies, while heavy rains continued in the South. Some severe
thunderstorms occurred in Texas, Colorado, western Kansas,

Arkansas, Louisiana, and South Carolina, along with some heavy
rainfall in northern Oklahoma on Friday. Saturday, thunderstorms
produced locally heavy rains in the South. Isolated 2-inch |
rains were also reported from southwest Missouri and western
Iowa and 1.25 inches at Scottsbluff, Nebraska. Sunday, thunder-
storms were triggered by a cold front that trailed from the
central Great Lakes into the middle Mississippi Valley. Else-

where, widely scattered thunderstorms dumped locally heavy rains

on parts of New Mexico and western Texas. Roswell, New Mexico,
measured 2.32 inches of rain in only six hours,

TEMPERATURE: Cool weather blanketed most of the Nation last week.
Temperatures averaging from 9 to 10 degrees below normal were
reported in Nebraska, Kansas, Texas, and Wyoming. The second
consecutive week of below-normal temeratures prevailed across

the dry central United States. Only sections of California,
Oregon, WaShington, the Great Lakes, Pittsburgh, Pennsylvania,
and Miami, Florida, reported temperatures near normal or above.

A cool High pressure system brought new record morning low
temperatures to the Nations midsection on Monday. Records were
set from as far west as Casper, Wyoming, with 47 degrees and as
far east as Cincinnati, Ohio, where a new record of 53 degrees
was recorded. Tuesday morning, temperatures dipped to record lows
in Nebraska. North Platte recorded the third record low tempera-
ture for the month with a reading of 42 degrees, while Omaha

and Grand Island recorded record breakers for the fourth con-
secutive morning with readings of 48 degrees and 49 degrees,
respectively. Wednesday, fair weather prevailed over most of the
Nation west of the Continental Divide in the Plains, Great Lakes
region, and Northern Atlantic Coast States, but temperatures

were only in the 70's and 80's. Thursday, temperatures were below
normal for the season over just about all the Nation. Highs were
mostly in the 80's. Temperatures reached the 80's and 90's across
the country on Friday. In the northern sections, temperatures in
the 60's and 70's were recorded. Saturday, Denver, Colorado,
dropped to 45 degrees setting a new record morning low. Pleasant
weather continued over the Northeast as a cool, dry Canadian air
mass settled over the area. Most of thé area west of the Rockies
enjoyed fair weather with afternoon temperatures climbing into
