PEST SURVEY


Vol. 18 August 1, 1938 No. 6



THE MORE IMPORTANT RECORDS FOR JULY

By the end of July effective baiting for grasshoppers gave a very high
degree of control throughout most of the infested area, especially where
idle lands did not breed tremendous populations. In the southern and
western counties of North Dakota, and in counties of South Dakota west of
the Missouri River, as well as in the eastern part of Wyoming and in 15
eastern counties of Montana, enormous populations of Molanoplus mexicanus
developed in idle lands in which effective baiting was not accomplished.
General migrations of adults began about July 4 and were observed at
different times until about the latter part of the month. The flights
were in northwestern, western, and southwestern directions from the western
portions of the Dakotas, eastern Montana, and eastern Wyoming.

The 1.ornon cricket infestation of south-central North Dakota is very
much heavier than it was last year, with but little damage occurring,
however. Contiguous to this infestation a light infestation extends almost
across the State of South Dakota. A similar light infestation occurs in
central and western Nebraska. Heavy migrations arc occurring in the Judith
Basin in Montana and some damage is being done in parts of Wyoming. Heavy
infestations, representing migrations moving down from mountainous areas in
which control was not conducted this year, are occurring at points in
southern Idaho, with damagc being reported in places to alfalfa seed pro-
duction. In Nevada there arc several areas of rather heavy infestation,
while in Utah, eastern Washington, and northeastern Oregon are several
scattered outbreaks. The infestation in Colorado has been reduced to in-
significant numbers. The cricets, for the most part, are mature and c-,i
laying is well under way although apparently it has not reached its peak
over most of the infested area.

Several species of wireworms wore reported as doing damage in limited
areas in South Carolina, in the Great Plains States, and California.

Japanese beetle was much more abundant than during preceding years in
southwestern New England, southeastern 'Jcw York, in Delaware, northeastern
Maryland, and the Eastern Shore of Maryland and Virginia.

BULLET IN











The Asiatic garden beetle has been reported as increasing in abundance
in the District of Columbia and nearby Maryland.

The white-fringed beetle has been discovered in the following localities
heretofore not known to be infestod:A rather general infestation in the
vicinity of Monroeville, Monroe County, Ala.; Conecuh County, Ala.; Mobile,
Ala.; Pass Christian, Harrison County, Miss.; Bolton, Hinds County, Miss.;
Carriere, Pearl River County, Miss.; and with a general extension of the
area known to be infested about Gulfport,-Missa:,---and New Orleans, La.

Tho stalk borer was reported as doing considerable damage to tomatoes,
sweet corn, and several flower-garden plants from New York to Maryland and
westward to Missouri and Nebraska.

The beet webworm was locally abundant on sugar beets and garden plants
in parts of the Great Plains and the Great Basin.

Armyworm outbreaks were reported from Now England, Middle Atlantic,
East Central, and Plains States.

Corn ear worm seems to be about normally abundant throughout the
Eastern and Southern States.

Heavy infestations of sweet corn by European corn borer were reported
from Connecticut, New York, Now Jersey, Ohio, and Indiana.

No serious chinch bug infestations developed in the East Central States.
This insect, however, did considerable damage in limited areas in Missouri,
Iowa, and Texas.

Three additional counties, Box Butte, Kimball, and Banner, in western
Nebraska, one county in northeastern Colorado, three counties in north-
central Wyoming, and two counties in southeastern Wyoming not previously
known to be infested by the alfalfa weevil were found infested this year.
The insect was also found in southeastern Douglas County, Oreg.

Codling moth infestations in the Eastern States were generally normal
to subnormal during July.

Fruit aphids, particularly the rosy apple aphid, were somewhat more
abundant this month in the Middle Atlantic and New England States, westward
to Minnesota, Missouri, and Kansas.

Oriental fruit moth is reported as moderately abundant in the New
England, Middle Atlantic, and South Atlantic States, but seems to bo on the
increase in parts of Virginia, northern Georgia, and parts of Ohio and
Kentucky.









-315-


Late peaches in central Georgia wore heavily infested by second-brood
plum curculio. Severe damage was also reported from Mississippi, parts of
Ohio, and Michigan.

Rather heavy infestations of grape leafhopper were recorded from New
York through the Lake States to the Great Plains and in Utah.

Colorado potato beetle has been found on the western edge of the Twin
Falls area, an important potato-growing section in south-central Idaho, not
previously infested. This insect is also more abundant than last year in
the Ogden-Clinton area of Utah.

Potato psyllid was causing very serious damage to potatoes in the North
Platte River valley in Nebraska.

The potato leafhopper is more abundant than it has boon for several
years in Ohio.

The harlequin bug was reported in damaging numbers in Delaware, Maryland,
Kentucky, Tennessee, Missouri, and Oklahoma.

Blister beetles were very generally reported from most parts of the
country, often doing serious damage to truck and flower gardens.

Heavy infestations of forest tent caterpillar are reported from Ver-
mont, Massachusetts, and New York.

General infestations by bagwormn are reported from Delaware southward
to Georgia and in the lower Ohio Valley States; also from parts of Texas.

Elmn leaf beetle was reported as quite generally prevalent in the New
England and Middle Atlantic States, southward to Virginia and westward to
Ohio.

Walnut caterpillar was unusually abundant in the Ohio and Mississippi
Valleys.

A very heavy outbreak of chironomid midges occurred during the month
in the artificial lakes oand lagoons on the site of the New York World's Fair.

The Lone Star tick was collected for the first time in New Jersey
this year.

THE MORE IMPORTANT ENTOMOLOGICAL FEATURES
IN CANADA, FOR JULY, 1938


Dry weather in Manitoba, in July, resulted in increased grasshopper
activity which necessitated the use of poisoned bait generally throughout
the southwestern part of the province. Maturing grasshoppers were caus-
ing some anxiety towards the end of the month, but damage had booeen compar-
atively light. In Saskatchewan, rains improved the grasshopper situation,
but severe damage to the wheat crop by these insects continued in the
southeast and northwest areas, with scattered trouble elsewhere. In some
districts the grasshoppers moved from unpoisoned summerfallow, causing
much defoliation generally, and forcing considerable cutting of the crop
for food. By July 19 heavy flights wore beginning in the southeast.
Early in July, grasshoppers were causing minor crop losses in certain
areas of Alberta. Grasshopper depredations in the interior of British
Columbia were aggravated by dry weather conditions.

Light to moderate outbreaks of the armyworm occurred in several
areas in Ontario, and locally in the Brandon district, Manitoba.

Say's stinkbug is abundant in southern Alberta in localized areas.
The infestation is concentrated in the Taber-Barnwell district, and is
more severe than at any time since observations were commenced in 1936.
Some losses have occurred along the margins of grain fields.

There is a general infestation of wheat stem sawfly over large areas
of Alberta and Saskatchewan. Throughout the greater part of the infested
area there are good crop prospects which will facilitate oviposition. This
year there is a tendency for the very severe infestations to occur along
the field margins.

The Colorado potato beetle is reported to be unusually abundant
throughout its range in the Dominion.

Cucurbits have been severely infested by the striped cucumber beetle
in southwestern Ontario, and locally elsewhere in Ontario and in Manitoba.
For the first time the species occurred in economic abundance in Saskatch-
ewan.

The beet webworm developed in great numbers in the provinces of
Manitoba, Saskatchewan, and Alberta, and in many districts caused moderate
to severe losses in garden crops. The activities of the insects were in
part beneficial, in that they fed upon noxious weeds.

The imported cabbage worm was reported unusually injurious to early
cruciferous crops in southwestern Ontario, and very scarce in southern
Alberta.









-317-


The codling moth infestation is about average in the Yiartra district,
Ontario. In the Okanagan Valley, British Columbia, unusually heavy infesta-
tions were expected following prolonged dry hot weather.

In the Niagara fruit district of Ontario, the oriental fruit moth is
at a low level. In the more heavily infested peach orchards in south-
western Ontario, the parasite situation is very encouraging.

Thirty percent of the cherries growing on a farm near Brentwood
(Vancouver Island), British Columbia, were infested by the cherry fruitfly.
Prior to 1937, this species had not been observed in the district since 1906.

Another year of heavy infestation by the European spruce sawfly is
expected in the Gaspo Peninsula, Quebec. Collections from southern Ontario
have shown that the species is well established and abundant at Galt, Toronto,
and Guelph. It has also been taken near Barrie, Angus, Peterboro, and
Lindsay." No previous records are known from this region.

The spruce budworm appears to be very active throughout southern
Ontario and in northwestern Ontario, east to Dryden. An infestation also
appears to be building up in southern Ontario.

GENERAL FEEDERS

GRBASSHOPPEPS (Acrididae)

Wisconsin. E. L. Chanmers (July 23): Only about 75 percent hatched. Very little
crop damage, mostly in the northweostorn quarter of the State.

Ohio. T. H. Parks (July 25): Grasshoppers present in no more than usual numbers,
and no injury expected in any part of the State.

Indiana. J. J. Davis (July 26): Quite a few cases reported of grasshopper
abundance in vegetable and flower gardens, but no conspicuous outbreaks
in the State.

Illinois. W. P. Flint (July 23): Grasshoppers have decreased greatly during the
last month, owing to frequent and hoavy rains. Present indications are
that very little damage will occur in Illinois.

Michigan. Michigan Extension News (June): Control operations are under way in
a nurab:r of counties in the northern half of the Lower Peninsula.

Minncsota. A. G. Ruggles and assistants (July): Grasshoppers are moderately to
very abundant generally throughout the State.

Iowa. C. J. Drake (July 20): The population is quite heavy in western and south.
western Iowa, but more than normal numbers of hoppers occur here and there
throughout the State. Most of the damage up to the present has been done
by the two-striped rasnshoppor (Melanoplus bivittatus. Say), but the lesser
migratory (M. mexicanus Sauss.) and the differential grasshopper (j. differ.
entiali. Thos.), also occur in destructive numbers. Timely rains have
destroyed large numbers of newly hatched hoppers throughout most of the
State. Unusually large numbers of hoppers supported by wild growth, thus
being kept out of cultivated crops.

H. E. Jaques (July 24): The grasshopper situation is serious along
much of the western border of Iowa.

Missouri. L. Haseman (July 23): Grasshoppers have continued to be abundant but
scattered throughout the State during the month. The lesser migratory
species is much less abundant than a year ego and in the vicinity of
Columbia largely gone. Two-striped hoppers have been attracting greatest
attention up to the present and are now mostly- nature, with fully developed
eggs. The differential grasshopper is beginning to mature, although most
of them are still in the nyimphal stage. The common Carolina locust
(Dissosteira carolina L.) is maturing in the vicinity of Columbia and promises
to be as abundant as it ".ns a year ago.

North Dakota. J. A. Munro (July 22): Flight dispersal of the more migratory forms
is commonly observed in practically all parts of the State. The migrations
are especially pronounced in the south-central and southwestern areas. In
general, the flig-hts have been mainly in a north-estern direction, although
flights in other directions have occurred on warn days with the prevailing
wind currents. Observations made in the southw.central area on July 2
showed the predominating species, to be M. mexicgnua, while inspection in
the same locality 2 weeks later showed a marked shift in species, owing






-319-


apparently to M. mexicnnus having dispersed by flight, leaving M. differ.
ontialis, M. packardii Scudd., and otht.r less mit;ratory forms relatively
nero abundant.

South Dakota. H. C. Severin (July 9): ILany M. nexicanus and a few M. bivittatus
were nature by June 22. At present, ej:s of If. mexicanus, M. bivittatus,
It. difforontialis, and D. carolina are still hatching. Flights have
occurred during the last 2 .eoks. Considerable crops will be lost despite
successful control measures, owing to so much idle land whore the hoppers
brood and from which they nre nigrating.

Nebraska. M. H. Swvenk (July 23): Flights are commonly observed by the middle of
July. The two-striped -rasshopper was first noted as having retched the
adult strige at Lincoln on June 18, and adults wore numerous by Juno 24
over most of eastern Nebraska.

Kansas. J. R. Horton (July 22): A moderately heavy migration of grasshoppers
observed passing over Wichita on several days during the first week of
July, at the sane time that the number of individuals in local fields de-
creased naterially. The migrations are believed to have started here, or
to h:ive been joined by local hoppers; hoe;over, there are still mancr left,
and they are doing considerable damage.

H. R. Bryson (July 28): Less abundant in the eastern and central parts
of Kansas than earlier in the season. In the western psrt of the State they
are still doing some damage but are mostly well under control.

Oklahoma. C. F. Stiles (July 22): Owing to the control program, grasshoppers
have not danaged the crops seovorely in Oklahona, Tho number of -*rass..
hoppers is greatly reduced in the northern part of the State through
control monauros and some natural enemies, but the- are present in large
numbers in the southwestern quarter of the State. The principal species
are M. differentialis and M. packardii. M. bivittatus is rapidly dis-
Tppearing, the sane holding true for M. =xicnnun. Nnmphs of an undeter-
mined species in the second and third instar are showing up in large
numbers in Kay, Caddo, and Grady Counties, especially in alfalfa fields.
A report frnnom Cinarron County, the e-.trcne Panhandle county of the State,
states that D. longipennis Thos. are nor flying into the county.

E. E. Ivy (July 25): Grasshoppers did considerable injury to young
cotton at the edges of many of the fields in flcCurtain Coimnty, southeastern
corner of the State,early in the season, but at present the cotton is
easily outgrowing the injury.

Montana. R. A. Shoals (July 30): Ccnsidora' le crop loss occas ione, `nrin- the
last fow weeks in eastern "Montana by hordes of grasshoppers, which had
ni-rated into agricultural areas from nearby breeding -roundc in ran e
lands or waste areas. Flights were so heavy that damage occurred despite
extensive control measures.

Utah. G. F. Knowlton (July 12): Grasshopprs arco -iore Obudannt and damagin(n tVi:t
since 1931. Approximately 75 percent are adult in some localities, with
lare.-scalo hatching still occurring in some areas.





-320-


(July 25): Fungous disease killing many grasshoppers in the Paran-onah.-
Parowan area, southwestern Utah. This occurred in 1937 but did not pre-
vent heavy outbreaks in the area this year.

Ncvnw.a. G. G. Schweis (July 25):. Grasshoppers, principally M. mexicanus, are
occurring in groat numbers and control campaigns aro necessary in several
counties. Much da&nae reported to second-crop alfalfa.

California. C. C. Wilson (July 9): Infestation by M. devastator Scudd. in the
grazin. land of the foothills of 15 counties is nore serious than in 1937.
In Lesson County nore than 400 grasshoppers per square yard were present
in alfalfa. In Little Shasta Valley, in Siskiyou County, serious damage
to alfalfa and grain was experienced; whereas in the San Joaquin Valley
they 7oere less numerous than during the outbreak of 1936, although the
population is still sufficient to cause damage. j. marginatus Scudd. and
M. ferir-ibrun Doi. appear to be increasing in the alfalfa fields of
Sacramento County. The -axinun count in one alfalfa field was 1,224, with
a nou-in of 384 per squa-re yard. The grasshoppers at this density, and
mostly in the second and third instars, were sufficient to destroy 50 per-
cent of the second cutting of hay before it reached maturity.

C. S. Morley (July 8): One of the major insect problems in Kern County
during the last month is the control of erasshoppers which have begun to
cone in on the agricultural crops from dry pazture land, where they have
been --.cro abun&nt than for many years.

MORMON CRICKET (Anabrus simplex Hald. )*

Sruth Dakota. H. C. Severin (July): Mornon crickets are doing sono damageo.
Fully 85 percent are adult. More crickets present than ever in the history
of the State. For a complete report on the Mormon cricket soc pp. 324
and 325.
Nebraska. M. H. Swenk (July 23): The easternnost points from which this pest
has been reported in Nebraska are Oshkosh, Garden County, on July 15, and
Purdun, 3laine County, in the center of the Nebraska sandhills, on July
20. In the latter locality they were plentiful, diggVing holes in the
around to a. depth of 6 to 8 inches.
Nevnad. G. G. Schwois (July 25): Mornon crickets are as abundant as in 1937, and
a seonminly decided increase in the population westward.

WIREWORMS (Elatericlae)

South Carolina. 0. L. Cartwrijht (July 13): Unusually severe injury from wire-
worms, chiefly Horistonotus uhlorli Horn, is being eoxeorienced in Colleton,
Haptnn, Jasper, Dorchouztor, Horry, and other coastal counties of the
State durinI the present season. A considerable acreage of corn will be a
complDte failure because of the worms.
Iowa. C. J. Drake (July 20): Wireworns have daxiaeod some corn in the vicinity of
Hawarden nud Dysart, sone of the fields being very heavily infested.
For a complete report on the Mormon cricket, see pp'. 324 and 325.






-321-

of the wireworm, Monocrepidius vespertinus: F., attacking the 16owcr portion
of cornstalks.

California. R. E. Campbell (July 1): Dar'.-;c from the sugar-boet wirc-'rrm
(U.inonius californicus Mann.) is continuing, in a large number of lima bean
fields in Ventura County, southern part of the State, varying frr, no
apparent damage to at least 50 percent. In several fields there wore
larg-oe bare spots several acres in extent, in which practically all of
the plants had been killed, while in other fields danag e was scattered
throughout the field.

M. W. Stone (July 17): L. californicus larvae were observed feeling
on young corn plants near Downo, Los Angeles County, as late as July 9.
Damaf c was so severe that replanting of over 3 acres was necessary.

FALSE WI1EORMS (Eleodoe spp.)

Kansas. J. R. Horton (July 22): Adults of the false wireworms, E. suturalis Say
and Z. tricostata Say, seen more frequently in the Wichita area than dur-
ing the last 2 years. Apparently they are on the increase, although not
nu.iorous -'t any point so f'-r observed.

JAPANESE BMETLE (Popillia japonica Newn.)
New En-la.nd. E. P. Felt (July 22): This pest has been much nmoro abundant and
destructive in southwestern New Eniland and southeastern New York than in
prccodirf- years.

Connecticut. J. P. Johnson (July 22): Bridgeport, New Haven, Greon,-ich, Hart.
ford, New London, Norwich, lNow Cana-In, mnd Danbury are n-ne-l in order of
infestation. The first four towns a(re heavily infested in !ocod-sized local
areas. In the other towns the infestation ranges from general to light in
localized areas. As a whole the beetle is very troublesome, and nany small
areas are comparable to New Jersey infestations. '

Rhode Island. A. E. Stone (July 29): Japanese beetle increase tremendous in the
older infestation, and there are quite a number of now places where they
have never ')eon previously reported.

ruined by the beetle in Cecil County. Over 20,000,000 beetles captured
on two farms alone. Also reported from the Eastern and Western Shores as
apparently increasing in ntmbere.

Virginia. H. G. Walker (July 26): The insect seems to be much more abundant at

MORMON CRICKET (Anabrus simplex Hald.)


North Dakota. T. J. Schmitt, Jr. (July 29): Farmers in Emmons County
estimate there are 50 times as many crickets present as last year,
but so scattered that no damage is apparent. Concentrations becoming
more noticeable in the hills and uncultivated fields. Bands now
scattered in Burleigh County over a wide area. Half the townships in
Mclntosh County infested but infestation not heavy.

South Dakota. T. J. Schmitt, Jr. (July 29): Lynan County lightly infested,
with a moderate infestation on the Brulo Indian Reservation, all
crickets in the adult stage, females predominating. Oviposition in
progress. Light infestations in Hand, Jorauld, and Buffalo Counties,
with egg laying in progress on the high ridges. Peak of egg laying
expected in about 2 weeks. Infestations in Potter, Walworth, and
Campbell Counties apparently moved eastward onto agricultural and
range lands. All crickets in the adult stare and egg laying taking
place in Walworth and Potter Counties. About 30 to 40 thousand acres
in north-central McPhorson County lightly infested.

Nebraska. T. J. Schmitt, Jr. (July 29): Infested area in Scotts Bluff
County about 10 miles long and 6 miles wide. Population very light
and widely scattered. Light infestations of Yornon cricket, or a
related species, in Cheyenne, Garden, and Lincoln Counties.

Montana. T. J. Schnitt, Jr. (July 29): Crickets in the adult stage through-
out the State, and laying eggs quite heavily. Heavy migrations from
the range and mountainous areas in Judith Basin County. Infestation
greatly reduced in the Big Coulee area of Stillwater and Golden Valley
Counties. Most of the egg beds in Sanders County found in lower areas.

Wyoming. T. J. Schmitt, Jr. (July 29): Ori-inal infestation apparently
in the Sixty-six Mountains on the state line between Nebraska and
Wyoming. Crickets in Goshen County very heavily bunched and causing
danazo to wheat in this area 2 weeks ago, but now spread over several
thousand acres of wheat and range lands. Peak of egg laying not ex-
pected for 2 or 3 weeks. Most of larger bands of crickets near crop
areas in Sheridan and Johnson Counties destroyed, or scattered. Many
small bands found to be brooding and laying eggs in areas whore control
operations have not been practical. Ovipositing in Campbell County.

Idaho. T. J. Schmitt, Jr. (July 29): Control measures to be concluded in
Elmore County on August 1. Production of alfalfa seed in this area
liable to necessitate extra work. Oviposition not complete and some
crickets still mating. In Tashin.ton County crickets in rather con-
centrated bunches, doing considerable damage to alfalfa seed. Excep-
tionally heavy migrations from the Forest Reserve toward agricultural

hornvorn appeared in the entire to'.acco territory, on the Western Shore.







-355-


POTATO FLEA BEETLE (Epitrix cucumeris HIarr.)

Connecticut. A. W. Morrill, Jr. (July 12): Ordinarily the second brood appears
about July 1 and reaches a maximum about July 23. This year tho in-
festation at the first of the season, when tobacco was set on Juno 1, was
as severe as last year and nore severe than normal. However, it was not
until July 12 that the first individuals of the second brood could be
found on a few tobacco plants and in some potato fields. (July 27):
3nergence of the beetle in appreciable numbers occurred in a few shade

beetle has not appeared in anythinG like normal numbers.


TAIUISHED PLANT DUG (Lvgus pratens is L.)

Connecticut. A. W. Morrill, Jr. (July 5): There is a severe infestation on one
side of a field in Collinsville, Hartford County. Plants had been attack-
ed while the leaves were still in the bud and the loaves wore badly mis-
shapen. In general this insect has not done great damage.


GREENHOUSE 7HITEFLY (Trialeurodes vaporariorum Westw. )

Florida. F. S. Chamberlin (July 12): Founu1 in several fields of shade-Crown
tobacco in Gadsden Comity this season. In three shades the fedclin- of the
insects and the accompanying sooty mold caused appreciable injury to the
crop. Whiteflies were found in fields of sun-grown tobacco but the feed-
ing caused no economic loss. Whiteflies have been collected on tobacco
in this region in the past, but, previous tn this season, no instances
had been observed where the insects have caused danaoe of economic
importance. (Det. by G. 3, Morrill.)

CAS TOR BEAI

SOUTIHE ARMWOM! (Prodenia eridania Cram.)


Florida. J. 11. Watson (July 22): A commercial planting of castor beann in
Manatee County, on the West coast, was seriously attacked by the semi-
trcpical arr7rworm.

Note: We are proparin2 a paper on the insects attacking the castor-Ie-.n
plant wherever it grows. We are, therefore, nmkin.- a special request
that the workers examine plants for insects this sum-nor and fall and send
the findings t- us. We should also zmpreci-ite m.r records you nay have
on hand.

COTTON INSECTS


BOLL WEEVIL (Anthonomus grandis Boh.)

South Carolina. F. F. Bondy and C. F. Rainwater (July 2): In Florence
County the first new weevils appeared on June 28. In 14 untreated
plots the infestation averaged 7.7 percent. (July 16): In 16 un-
treated cheok plo% the' oLyfetoaton averaged 12 percent. (July 23):
Weevils are increasing very fast and in many fields the infestation
has reached 50 or 60 percent. The weevil situation in Florence County
is more serious than for several years.

Georgia. P. M. Gilmor and P. A. Glick (July 10): In undusted Upland
cotton in southern Georgia from 18 to 50 percent of the squares were
punctured, and in Sea Island cotton that had been dusted the field
average was 8 percent. (July 17): iany late fields of cotton have
been seriously injured. Second brood is pupating. (July 24): Second-
generation weevils began to appear on July 18 and by the 23rd were
present in considerable numbers.

Florida. C. S. Rude and L. C. Fife (July 16): In 30 fields examined the
infestation was increasing rapidly. Lake County showed no infestation
in eight fields examined. In the northern counties the infestation
ran from 12 to 92 percent. (July 30): In Alachua and Gilchrist
Counties the square infestation ranges from 10 to 91 percent and in
many fields the bolls are heavily'infested. In Marion County the in-
festation is increasing and ranges from 10 to 91 percent. The only
field in Lake County thus far found to be infested has 30 percent
infestation.

Mississippi. R. L. McGarr, et al. (July 9): In Lowndes and Oktibbeha
Counties an examination of more than 10,000 squares in 15 untreated
fields showed an average infestation of 18 percent as compared with
12 percent for the previous week and 2 percent at this time last year.
(July 23): An examination of 10,600 squares in 19 untreated fields
showed an average infestation of 28.5 percent.

E. W. Dunnam and J. C. Clark (July 2): In Washington County
infestation counts made on seven plantations showed that the per-
centage of infested squares varied from less than 1 percent to 70
percent, with an average of 29 percent infested. (July 30): On
three plantations the average infestation vwas 49 percent.

Louisiana. R. C. Gaines, et al. (July 2): In Madison Parish 52,800
squares wore examined from untreated cotton, of which 2,157 were
punctured, or an average infestation of 4.1 percent. (July 30):. The
infested squares increased to an average of 36 percent in 19 untreated
fields examined; the infestations ranged from 7 to 69 percent.






-357-


Arkansas. D. Isely (July 20): The boll weevil was quite generally dis-
tributed over the cotton-producing part of the State by early July,
where it is more generally distributed than in any year on record
except 1923 and 1932. Since then excessive dry weather has appeared
to have chocked its development in many counties.

Oklahoma. F. A. Fenton (July 22): The infestation continues to be throat-
enin.g; however, a 2-week period of hot, dry weather in early July has
apparently checked the infestation somewhat.

C. F. Stiles (July 22): Appearing in larger numbers in south-
eastern Oklahoma than they have in a number of years.

E. E. Ivy (July 25): Infestation in McCurtain County has increased
steadily since early in .lay. Still somewhat spotted, some fields
having from 50 to 60 percent of the squares punctured, others having
less than 10 percent. Average probably near 25 or 30 percent at present.

Texas. R. W. Moreland and A. B. Beavers (July 2): In Brazes and Burleson
Counties in untreated chock plots in cotton fields the infestations
in cotton squares ranged from 12 to 31 percent, averaging 19.5 percent.
(July 30): In the untreated chock plots the infestations ranged from
14 to 77 percent, with an average of 45 percent. In the treated plots
it ranged from 2 to 31 percent, with an average of 12 percent. In the
untreated upland fields it ranged from l4 to 79 percent, with an
average of 47 percent.

K. P. Ewing, et al. (July 2): In Calhoun County 1,100 squares
examined in 11 untreated chock plots showed an average of 6.2 percent
boll weevil punctured squares as compared with 3.2 percent last week.
In Jackson County 17,600 squares were inspected in 11 fields which
showed an average of 78 percent weevil punctured squares. (July 30):
In Calhoun County the infestation was 3.6 percent. In Jackson County
the infestation decreased to 12 percent.

A WEEVIL (Epicacrus formidolosus Boh.)

Florida. C. S. Rude (June 30): Has beeoon very abundant in the cotton
fields in the Gainesville area. Estimated to be about 1,000 per acre
in experimental fields, but somewhat less abundant now. Found in
exactly the same parts of the cotton. plant as the boll weevil and
constant care required while making weevil counts not to confuse the
two insects. No damage found that could be directly connected with
the insect. Not found on weeds or other crops when area borderini-
those fields was searched. (Dot. by L. L. Buchanan.)

PI:r: BOLLWOP1 (Pectinophora gossypiella Saund.)

Texas. A. J. Chapman, ct al. (July 2): The bloom-infestation records in
the 12 fields in Presidio County were completed this week. The






-355-


results from the five records made in these fields showed the infesta-
tion to be extremely spotted. The infestation was unusually high in
the fields in which there was no winter pasturage or other cultural
practice that would tend to reduce the surface population. The fields
that were near retired cotton acreage also showed some increase in in-
festation. During 1937 a group of 25 fields was selected and only 1
examination of 1,000 blooms in each field was made during the latter
part of June. From the 25,000 blooms examined there were 843, or 3-37
percent, infested. In 1938 a group of 12 fields was selected and 5
records were made in these fields during the latter part of June.
The total number of blooms examined was 16,901, averaging 1,40g per
field, and 513, or 3.03 percent, were infested. (July 9): Boll in-
festation counts were made in one field in connection with the in-
secticide tests. There was an average of about one boll per plant at
the time that the record was made. Eleven of the 100 bolls examined
wore found to be infested. Since these wore the first bolls formed it
is apparent that there will be considerable damage in this field by
the close of the season. The field showed a high bloom infestation.
The cultural practices in this field were favorable for a high survival
as the stalks were not cut until late in the fall and wore not plowed
under until spring. (July 16): Bloom-infestation records were made
in the lower El Paso Valley (Hudspeth County) on July 5-7. The fact
that an infestation was found this carly in the year would indicate
that the worms had passed the winter in this area. (July 23): Bloom-
infestation counts were made in the Balmorhoa area during the week
ending July 16 with negative results.

COTTOIT LEAF WOPIv (Alabama argillacea Hbn.)

Mississippi. C. Lyle (July 25): First specimens found this year in
Holmes County, central Mississippi, on July 16. Found in Oktibboha

to sixth were found in one field near Delta Point, in Madison Parish.
(July ): L>rvae found about l14 miles south of Tallulah, in Madison
Parish. (July 23 and 30): Leaf worms have been found in practically
all fields of succulent cotton but not in sufficient numbers to cause
"ranging."






-359-


Arkansas. D. Isely (July 20): First record for 1939 received from Columbia
County, southwestern Arkansas, on July 16.

Oklahoma. C. F. Stiles (July 22): First worms this year collected on July
16 in Garvin County, south-central Oklahoma, one of the earliest
collections of this insect this far north in the State.

Texas. R. W. Noreland ;'nd A. B. Beavers (July 2): Several cotton loaf
worms wore collected during the week in Brazes and Burlcson Counties.
(July 16): Loaf worms were doing considerable "ragging" on some
farms. Some dusting was done on a number of farms. (July 30): Some
dusting being done for second generation.

K. P. Ewing et al. (July 2): Many fields in Calhoun County have
been dusted during the week for leaf worm control. (July 9): Most
of the leaf worms arc now in the pupal stage. (July 16): A new
generation has hatched in many fields and dusting is very general
throughout Calhoun County. A heavy infestation has appeared in the
Lavaca River bottom of Jackson County. The infestation is now as
heavy as it was at its peak in 1936. (July 23): The now gcnoration
of leaf worms of last week is completely under control. (July 30):
Leaf worns continue to hatch and control measures have been used in
many fields in Calhoun County during the week.

A. J. Chapman et al. (July 9): Leaf worms were found near Pre-
sidio on July 7. This is, so far as we know, the earliest record of
leaf worms in this area. The worms were full grown when found and had
already folded up leaves in preparation for pupation. The moths must
have reached here in June. This is apparently the first generation
as only a few worms were found. (July 23): Genernl infestation but
not yet abundant enough to cause serious damage.

BOLLWORM (Heliothis obsoleta F.)

South Carolina. F. F. Bondy and C. F. Rainwater (July 16 and 30): A few
found feeding in squares in Florence County.

Georgia. P. M. Gilmer and P. A. Click (July 10): Near Tifton bollworms
are in most fields in small numbers. (July 24): Appearing in sonc
numbers, but no serious damage to date.

Florida. C. S. Rudo and L. C. Fife (July 2): Not as numor'us as a few
weeks ago in Alachua and adjacent counties. (July 30): There are a
few in almost all fields but in general they are causing little danaoe.
In a few fields they are serious.

Mississippi. R. L. McGarr, et al. (July 16): Observed on cotton oc-
casionally this week in Lowndes and Oktibbeha Counties.

E. W. Dunna-_, and J. C. Clark (July 2): A few noted on two
plantations in Washington County.

Louisiana. I. J. Bocnol (July): Damaging young cotton bolls in several
northern parishes.

Oklahoma. E. E. Ivy (July 25): A few worms soon in cotton during the
last week in McCurtain County, southeastern Oklahoma.

Texas. R. W. Moreland and A. B. Beavers (July 2): A few eggs noted on
cotton in both upland and bottom fields in Brazos and Burloson
Counties. (July 9): Ninety-one oags wore found in examining 2,000
cotton terminals in bottom fields. Eggs ranked from 0 to 19 per 100
terminals, with an average of 4.55 c,7s per 100 terminals. In an up-
land field of succulent cotton 800 terminals wore examined and 8 eggs

INSECT CONDITIONS IN HJWAII

By 0. 0. McBride


The Mediterranean fruitfly (Oeratitis cawitat. Wied.) population level
showed a 'radual decrease from April 1931 through 1934. In 1935 there was a
rapid increase in population level, reaching the peak in 1936. During 1937 tho
population level started to decline and at the present time, July 1, 1938, it
is at "bout the 1932 level. Parasitization records of the Mediterranean fruit-
fly parasite (pius humilis Silv.) for the period 1914.1933 shows thaf, this
species reaches its maxinum abundance during March to May. During March to Juno
1939 parasite records were made on 260,000 fly pupae, fi6ld collected, only 4
specimens being obtained. Since last October only seven specimens have been re-
covorod. These records are for the Island of Oahu.

Growers of Kauai have reported that the rice borer (Ohilo simplex Butl.)
in certain areas is causing considerable Idamage to rice and is more abundant than
for the paat 2 or 3ylcam."

The taro leafhopper (Megamelus proserpina Kirk.) on the Island of Oahu,
at Honolulu and Kaneoho, is less abundant this season and is apparently coming
under control.

D. T. Fullaway reports that coconut palm scale (PinasPi buxi Bouche) is
increasing on the windward side of the Island of Oahu. Twenty-five large coco.-
nut palms were killed during the month of June. The scale is quite bad on
'banonns. Several species of ornamental palms are attacked.
