THE MORE IMPORT4A:T RECORDS FOR APRIL

The outstanding event of the month was the outbreak of the army-
worm and the variegated cutworm in northwestern Mississippi, northeastern
Louisiana, and east-central Arkansas. Oats and alfalfa were the prin-
cipal crops injured.

The unseasonably cool rainy weather the second week in April and
the continued unfavorable weather delayed hatching of grasshopper eg-:s
over much of the infested territory; however, somn hatching has; taken
place in Utah, southca.stcrn Colorado, and northwestern T;::., and is
practically complete in Oklahoma and Missouri.

Eggs of the Mormon cricket have hatched throughout Montana.

Damage by cutworms was reported from many localities, the most
injurious being the variegated cutworm in the Delta counties of Missis-
sippi and Louisiana and the army cutworm in western IlTorth Dakota.

May beetles were observed at lights as far north as Ch:dbourn,
N. C., La Fayette, Ind., and Kansas. Only moderate injury was reported
generally but pecan buds in Georgia wore severely injured. Injury by
the grub of the green June beetle occurred in Kentucky, Tcnnrsee, and
Georgia.

The spring brood of the hcssian fly is emoLrging in Indiana. The
insect in the pupal stage withstood abnormally low temixrav:r:s in Kan-
sas the second wck of the month. The infestation in Pennsylvania is
light generally.

The chinch bug has passed the winter successfully but has been
slow in leaving winter quarters. The first noticeable flights occurreoi
during the last 10 days of the month in Indiana, Illinois, and Missouri.

The survival of pupae of the corn ear worm, or bollworm, ia
cages in New Jersey, Virginia, Ohio, and Texas was higher than in 1937,
and in Kansas survival was recorded^ for the first time, cages having
been run' for 4 years. The insect also survived in Utah.

The pea aphid is appearing on alfalfa and peas along the Atlantic
coast from Virginia to Now Jersey, A few pea fields on the Eastern' Shore
of Virginia are heavily infested. The insect is increasing rapidly in
the pea fields of southern Wisconsin. On the Pacific coast the survival
was high, but cold wet weather in March delayed reproduction until
April, when the insect became numerous on alfalfa and Austrian field peas
in Oregon and California.

The codling moth is pupating generally over the country and
adults wore observed as far north as Indiana. Mortality in Washington
is very low.

The eastern tent caterpillar is very abundant from Now Hampshire
to South Carolina and westward to Tennessee.

Apple aphids hatched rather abundantly, but many were killed in
Connecticut, New York, and Pennsylvania by cold weather. An Qutbreak of
the rosy aphid is developing in southern Indiana and western Kentucky.

The vegetable weevil is more abundant and destructive in Alabama,
Mississippi, and Louisiana than usual, A new infestation, several miles
from the known infested area, was reported from Texas. The insect is
unusually destructive in southern Qalifornia.

The Colorado potato beetle is abundant from Virginia, through
North Carolina and Mississippi, to Louisiana.

The Mexican bean beetle is coming out of hibernation in the Nor-
folk district, the first one boing taken on beans in the field on April 11,
which is 9 days earlier than ever before recorded in that locality. Wino-
tar mortality in Colorado is 39 percent; normal mortality is between 60
and 70 percent.

The harlequin bug is appearing in great abundance as far north
as Chadbournt, N. C

The potato leoafhopper was taken at trap lights at Arlington, Ta.,
2 weeks earlier than previously recorded.













The tomato worn is appcarin,- earlier than usual in the tobacco
district of northwestern Florida.

Cold v weather has delayed planting and has killca much cotton
that was planted c-rly. Planting has also been delayed by drou.uht in sono
areas and by too much rain in others. The cold dry weather in April has
delayed the ener ence of boll weevils in .any places. By the end of the
month *:.c:.ther conditions favored the -rowth of cotton and the weevils
wore reported as novin( into the fields.

Early in the season the cotton flea hopper appeared in gre t
abundance, but it received a set-back by the cold weather arnd at present
is no more than normally abundanIt.

The great number of reports of, abundance of cankcrworn indi-
cate that the insect is occurring in outbreak forn in the Middle Atlantic
States from ITew Hampshire to South Carolina, also in Ohio and Mississippi.

The forest tent caterpillar is reported in abuni- rnco in South
Carolina and KIississippi.

An introduced ahid, Myzus ornatus Laing, is occurring in abun-
dance at Berkeley, Calif., and has been discovered in Los Angeles County.

DialcurIdes chittendeni Laing is being reported from Connecticut
for the first tine.

GENERAL FEEDERS

GRASSHOPPERS (Acrididac)

Connecticut. A. W. Morrill, Jr. (April): Reports wore received on
April 15 that springtails had boon eating newly sprouted tobacco
soedli:-..-s in plant beds at Windsor, in west-central Connecticut, for
about a week. On April 23, 15 or 20 specimens were brought in and
proved to be very young nymph grasshoppers, probably Molanoplus
feriur-rubrum (Dog.). Also on the 23d, egg pods wore discovered in the
ground adjoining beds containing grasshopper nymphs almost fully de-
veloped.

Florida. J. R. Watson (April 23): Lubberly grasshoppers, Romalea microp-
t.ora (Bcauv.), have been very abundant in Clay and adjoining counties,
doing damage particularly to bulbs of amaryllis, narcissus, iris, and
other plants. They began appearing in large numbers late in March
and most of them are now in the second and third instars.

Minnesota. A. G. Rugglos (April 19): E :: have not hatched yet to any
extent. A few nymphs of Chortophaga sp. have been found.

Missouri. L. Hasoman (April 25): During the first days of April in some
of the southern counties and since the middle of the month at Colum-
bia, the lesser migratory Lraisshoppcr (IM. mexicanus Sauss.) has been
hatching and, in places, great numbers have hatched and are beginning
to feed.

Nebraska. M. H. Swenk (April): A report, with specimens, from Holt
County indicated that Hippiscus rugosus Scudd-., C. viridifasciata Dog.,
and Arrlia xanthoptora Burn. were found attacking young alfalfa in
that county. Specimens of mitcs, Eutrombidiunm trigonum Hermann,
wore received from Douglas County on April 2, with the report that
they were very numerous, presumably feeding chiefly on grasshopper eggs.

Oklahoma. C. F. Stiles (April 30): E-,"-s are hatching in all parts of
the State, and hoppers are doing a little d:r.'e in a few counties.
The pgrcentagec of hatch varies from 10 to 75-

Texas. F. L. Thormas (April 22): Grasshoppers continue to be a potential
menace in northwestern Texas. Snow probably aided. in protecting
those that had already hatched.

Montana. H. B. Mills (April 20): Several reports have boon received of
hatching of grasshoppers, but those that have been investigated have
disclosed nynphs of the overwintering C. viridifasciata.

Colorado. S. C. McCampbcll (April 19): Men are making surveys of egg
beds in migratory grasshopper (Dissosteira longiponnis Thos.) area.
We will h"ve an infestation involving so-nething over 4,000,000 acres
of this species. Er;s arc developing very slowly, owing to spring
rains and snows. It is estimated that it will be 3 weeks before this
species hatches.







- 91 -


Utah. G. F. Knowlton (April 16): E'-:s are abundant and in good condition
west of EThrain, in Sanpete County, central Utah, and near Trenton,
in Cache County, northern Utah. Little hatching has occurred, as re-
peated snow storms stopped hatching about the middle of March.

MORMON CRICKET (Anabrus simplex Hald.)

Montana. H. B. Mills (April 20): Mormon crickets are hatching generally
throughout the State, and field work on control will probably start
before the end of April.

CUTWORMS (Noctuidae)

New York. N. Y. State Coll. Agr. News Letter (April 25): The well-marked
cutworm (Agrotis unicolor Walk.) was found on April l1, feeding on
spinach in ITascau County.

New Jersey. J. B. Schmitt (April 22): Cutworms are abundant in rubbish
in and around fields. Some plants have been destroyed in coldframes.

Virginia. W. J. Schoene (April 20): Climbing cutworms are very common
on peach trees.

H. G. Walker and L. D. Anderson (April 26): Cutworns are moder-
ately abundant in some fields at Norfolk.

Georgia. T. L. Bissell (April 25): A corresp-n.rdort sent in 15 specimens
of Lycophotio. m-rgaritosa saucia Hbn. from 1 tomato plant in a .-reern-
hous'e at Qlarks'on, They were eating fruits. Since February 13, 14
moths have been taken in light traps at Experiment and 6 on March 23.

C. H. Alden (April 20): Cutworms have cut off about one-sixth
of the tomato plants set out in the last week at Cornelia. These are
much more injurious than last year.

Florida. F. S. Chamberlin (April 5): Cutworms caused relatively little
damage in fields of newly set tobacco this season in Gadsden County.

AlabaSna. J. M. Robinson (April 23): These pests have attacked onions,
cabbage, and tomato plants to a great extent in central and southern
Alabama.

Mississippi. C. Lyle (April 21): H. Gladney of Ocean Springs reported
that he had observed damage to tomatoes, berins, and corn in Jackson
County, and N. D. Pects, of Brookhaven, indicated that cutworms were
numerous in gardens and flower bees in his districts. iierous re-
ports from the -1t. counties indicate the heaviest inf. toh of
varioratod cucn;cr .L margaritcsa .u.? in sOveral ye':s. Much
damage is being done to all winter cc^r c ro-os. As riny as 20 or 30
worms under a single bur-clover or alfalfa plant were refprted in
some instances. Some alfalfa is bei:-..- destr ycd by mixed infesta-
tions of the armyworm (Cirphis unipuncta Haw.) and the variegated

cutworm, which is very abundant in alfalfa, bur-clover, and other
cover crops. "

Louisiana. R. C. Gaines (April 21): While in East Oarroll Parish on
April 20, wo visited a 62-acre field of bur-clover which had been com-
pletely destroyed by cutworms.

Tennossoee. L. B. Scott (April 1): Several cutworms per square foot wore
noted in many pastures in Montgomery County on March 30. -Several
cases of severe damIge have been noted in tobacco plant beds. It is
not uncommon to find five cutworms per square foot in pastures. Ob-
servations indicate an unusually severe infestation in north-central
Tennessee. It is much more severe than the heavy infestation in 1937.
Damage is particularly severe to corn, tomatoes, tobacco-plant beds,
and strawberries.

Kentucky. W. A. Price (April 27): Claybackod'cutworms (Feltia gladiaria
Morr.) are present in large numbers and are causing much damage to
young tobacco plants in the bedand to clov6r and alfalfa. They seem
to be generally distributed over the State.-

Michigan. R. Hutson (April 25): Cutworms are abundant in -'. Berrien
County about St. Joseph, in Van Buren County at Paw Paw, and in Manis-
tee County. The species reported at Manistec is A. unicolor.

Missouri. L. Haseman (April 25): Cutworm moths accompanied the flights
of armyworm moths during the first part of the month, but they were
less abundant than the latter., To date, no complaints of cutworms
have been received, but the partly grown cutworms are abundant in the
sod. Variegated cutworms bred from ec-s in the laboratory are now
nearly full-fed.

Arkansas. W. F. Turner (April 15): Peaches in Cross County are being in-
jured by climbing cutworms.

North Dakota. J. A. Munro (April 16): Infestations of the army cutworm
(Chorizagrotis auxiliaris Grote), though spotted, are'heavy enough to
indicate serious injury to crops as soon as plants are above ground.
Reports have been received from five or six of the western counties.

Kansas, H. R. Bryson (April 25): The moths of C. au:xiliaris were abun-
dant at lights during the second and third weeks of April. The larvae
did not cause much injury to crops because the garden crops in most
localities were not up. Thoy were reported causing injury to oats
at Republic.

Kansas. H. R. Bryson (April 25): Eriopyga incincta Morr., Parastichtis
bicolorago Guen., and Feltia venerabilis Walk. wore observed destroy-
ing the leaves of reclaimed sand-dune land at Ianhattan. The last
was also found in gardens.

Oklahoma. C. F. Stiles (April 30): Armyworms are generally distributed
over the southern part of the State.








- 93 -


Texas. F. L. Thomas (April 20): Cutworms have been severe in, g-eneral.
They appeared early and da-i-ned wheat in Baylor County. One farmer
lost 35 acres. Cutworms were abundant throughout March on lettuce,
potatoes, corn, and strawberries in Galveston County.

Colorado. G. M. List (April 23): The western erny cutworn (C. auxiliaris)
is doing noticeable d-na;e in some alfalfa fields in Larimer County.
Two specimens of Porosazrotis orthogonia Morr. were brought in from
a 30-acre field in Adams County in which the wher.t had been destroyed.

Utah. G. F. Knowlton (April 25): Cutworms are abundant in the sandy
cultivated land from Lakeview to Pleasant Grove, in Utah County.
Alfalfa is suffering most from their attack.

C. J. Soronson (April 22): Modoratoly abundant in alfalfa
fields in Cache County.

Arizona. C. D. Lebert (April 21): Noctuid larvae, Leucocnenis sp.,
severely defoliated ash trees in the Phoenix area. They hide under
the bark by day and feed in the new growth by night.

California. J. Wilcox and M. WV. Stone (Mlarch 25): Damage by Feltia annexa
Treit. was especially severe on lettuce at Costa Mese. Peas wcr'e also
attacked.

L'.0OTHS A-ID BUTTERFLIES (Lepidoptera)

Vermont. H. L. Bailey (April 20): The first specimen of the painted lady
(Vanessa cardui L.) was observed at Springfield, in thu southeastern
part of the State, today.

Connecticut. J. V. Schaffnor, Jr. (April 21): Cocoons of Philosamia
cynthia Drury are abundant in some sections of Ncv. Haven. J. E. R.
Holbrook and T. P. J. Duffy, of this laboratory, reTort then very
abundant in the vicinity of the Ihcw Haven freight yards, where there
are many ailanthus trees and saplings of natural reproduction.

Florida. J. R. Watson (April 23): The orang-e dog (P~apilio cresprhontes
Cram.) be.-an to be noticed on nursery stock early in April.

Louisiana. B. A. Ostcrberc-r (April l1): On the highway near Gonzales,
Ascension Parish, many larval stae cs, apparently of Esti:-.c:e acraea
(Drury) wore noticed nitrating across the paved highway.

Ohio. E. W. Mendonhall (March 30): The cecropia moth (Platysam ia cecropia
L.) is quite numerous this year. It- made its appearance early, about
the middle of M.:arch.

Utah. G. F. Knowlton (April 16): Mourning cloak butterflies (Har:-'ry-s
antiopa L.) have been seen on warm days in northern Utah since "'arch 6.

WIREWORIIS (Elateridae)

-CoYinecticut. A. W. Morrill, Jr. (April 1): Limonius agonus Say, which
usually appears about the end of April, was first observed in small
numbers under'freshly pulled stumps on March 16 at Windsor, in the
west-central part of the State. They were seen in the field when plow-
ing was begun on April 1, and have since been found in large numbers
in the soil, These fields will bb set to tobacco about June 1, at
which time untreated fields may be expected to suffer at least as much
damage as was recorded last year. Untreated.portions of the fields in
question did not produce marketable tobacco last year-and the expense
was increased by the fact that from five to six resettings by hand
were necessary.

Georgia. M. Mlurphoy (April 22): Larvae of Heteroderes laurentii Guer.
were collected in strawberry fruit grown at Atlanta. (Determined by
A. G. Boving.)

Kansas. H. R. Bryson (April 23): The true wiroworms have caused some
d:-tgc to wheat, in a few instances. Aeolus amabilis (Lec.) injured
spring wheat inr- some small plots at Junction City.

Utah. G. F. Knowlton (April 15): Wireworms were nurecrous in sod eoxmined
at Pctorson, in Morgan County.

Washington. H. P. Lanchcster (April 20): Melanotus orcgonensis Lec. has
been found in the adult stage during the l.st month at Walla Walla.
The larvae have buen noted only recently. L. infuscatus Mots. was
collected in both adult and larval stages from a nurmbcr of cultivated
fields, and in at least one instance was the prodominnzit form.

E. W. Jones (April 19): Larvae of the Pacific coast wireworm
(L. canus Lec.) and the sugar-beet wireworn (L. californicus Mann.)
wore found feeding on lettuce plants in gardens at Walla Walla as
early as April 7. Large numbers of the sur.r-beot wircworim were taken
by baiting in the week ended. April 18.

WHITE GRUBS (Phyrllophaga spp.)

North Carolina. W. A. Thouas (April 15): May beetles are just coning to
lights for the first tine at Ch.dbourn, but as yet are not very abundant.

J. F. Cooper (April 20): One-third of a 4--acre planting of wheat
in Alexander County was destroyed in February and March. No new
damv.ge was noted on April 13. Damage appeared only in those parts of
the field where wheat had been planted following lospedeza.

Georgia. G. F. Moznctte (April 4); P. forsteri Burn. and P. hirticula
Knoch have caused considerable injury to the opening buds and new
growth on pecan trees in orchards south of Albany. The damage has
been especially severe to the buds and r.eo; growth on top-worked pecan
trees, which were the first to put out in the spring. (Det., by P.
Luginbill.)








- 95 -


Mississippi. C. Lyle (April 21): Slight damage was done by May beetles
in one pecan orchard in Jackson County, according to H. Gladney, on
April 21, while I. D. Peets reported that he recently observed con-
sidcrable injury to pecan trees in the southwestern part of the State.

Louisiana. B. A. Ostorberger (April 21): June beetles have not been
very active since the cold weather the first part of April, which was
followed by heavy rains. The last few nights, flights have been very
light in East Baton Rouge Parish. The species collected ,were P. congrua
Loc., P. micans Knoch, and a few P. crinita Burm.

Indiana. P. Luginbill (April 25): The first May beetles to appear at
La Fayette were.a female and a male of P. forvida F., which were cap-
tured at traps on the night of April 19.

Kentucky. W. A. Price (April 27): May beetles begai flying in Lexington
on April 14. Lx

Kansas. H. R. Bryson (April 25): May beetles have booeen very abundant at
lights the last few nights. Larvae of the other broods arc causing
some injury in gardens and-strawberry beds.

GREEM- JLUVE BEETLE (Cotinis nitida L.)

Georgia. T. L. Bissell (April 15): Larvae have been damaging pimento
popper plant beds at:Zobulon, in central Georgia.

Tenn-ssee. L. B. Scott (April 26): The infestation on tobacco plants
in Montgomery County is about normal. Severe d-'.a. was nLoted
occasionally.

Kentucky. W. A. Price (April 27): Green June beetle larvae damaged
tobacco plants in the beds at Lexington, Versailles, and Danville.

JAPATIESE BEETLE (Popillia japonica Tewm.)

Maryland. H. C. Donohoc (April 22): ITu...I-ous samples of soil taken at
Princess Anne indicate an average population of more than 11 larvae
per square foot. The rvi-i .u-i obtained in any 1-square-foot sample
was 29 larvae. Vc-:.tation in the infested area is sparse native
cover, the most noticeable plant being wild strawberry, of which the
larvae appear particularly fond.

BLTr.2L FLOWZR BEETLE (uphoria inda L.)

Vermont. H. L. Bailey (April 22): Sevcrn.1 specimens wore collected at
Dorset, Bennington County, southwestern Vermont, today.

CEREAL AND FORAGE-CROP INSECTS


WHEAT AND OTHER SMALL GRAINS

ARMTIWOPU (Cirphis unipuncta Haw.)'

Virginia. H. G. Walker and L. D. Anderson (April 26): Larvae are injuring
oats and other crops at Norfolk and it is reported that they are
rather abundant on the Eastern Shore of Virginia. ,.

Mississippi. C. Lyle (April 25): A very destructive and widespread out-
break of the true ariayworm is occurring in several Delta counties.
First complaints were received on April 15. Most of the injury was
done to oats, but larvae were also found in alfalfa. Some of the heav-
iest da;iage is in Le Floro 3nd Sunflower Counties, although very ser-
ious injury was reported from various localities in Bolivar, Coahoma,
Quitman, Tallahatchie, Washington, Sharkey, Humphreys, and I.ssaquena
Counties. Some alfalfa is 1.in.- destroyed by mixed infdt.tations of
armywori and v.riegatod cutworm. Only a small percentage was parasitized.

Louisiana.. R. C. Gaines (April 20): Arrmyworms were observed'and reported
in M-.J ison anr.d .st Carroll Parishes. This appears to be a rather
serious outbreak. The insect was originally reported on April 15 in
Tonsas Ptrish and wa:; found in ever. oat field visited. Stripping was
in rapid progress throughout an entire field of 400 or 500 acres.
(Dot. by C. Hoinrich.) (April 19-2Q0): Infestations of true ar-,.,jorms
wore observed and *ropcorted on oats in Tcnsas, Madison, anrd East Carroll
Parishes. The darx:,;e appe-.rs to be most serious in Tensas, P-.arish.
Sone fields are being stripped now, and others apparently have enough
worms to cause complete stripping. Very little strippning has been re-
ported in. Madison Parish but there and in East Carroll Parish worms
can be found in many fields. The infestations appear to be light.
The worms in Madison Parish'and in ERst Carroll Parish, generally speak-
ing, appear to be smaller and less adv -.cod than those in'Tesas,
where ..:.ry of the wormr.s in some fields are about ready to pupate.
Lycophotia rargaritosa saucia Kbn. was taken in association with the
arm.yworm.

Missouri. L. Hasenan (April): During the first week in April armyworm
nmths wre extremely burj.nt throughout central Missouri, visiting
fruit blossoms. Following the severe freeze of April 8 and 9, moth
flights continued but moths w c!re leos .bundant hero. Following the
freeze in northwestern Missouri moths were reported as being extremely
abund'm.t. To date, no evidence of larvae has been reported.





Arkansas. D. Isely (April 19): There was an outbreak on oats in some of
the east-central counties where the insect was most destructive last
year. All oat fields scouted in Arkansas County wore infested.






- 97 -


California. A. E. Michelbacher (April 20): In the Patterson area the
armyworm was abundant in alfalfa fields the first part of April.

WHEAT 7HITE GRUB (Phyllophaga lanceolate Say)

Kansas. H. R. Bryson (April 23): These grubs cLUSCd a tremendous loss
to the wheat crop in the southern .and central parts of the State.

Oklahoma. F. A. Fenton (April 22): P. lanceolata is cousin: very little
injury at present.

HESSIAN FLY (Phytop:-a destructor Say)

Pennsylvania. C. C. Hill and E. J. Udine (April 21): Light infestations
prevail in fall wheat throughout most. of the State, except in -the East
where heavily infested fields were found in Bucks County. Ex.!minrition
of puparia from Cumberland County, made today, showed about 6-percent
mortality, 14-percent pupation, 12 percent emer--d. On this date- a
few scattered cFi in whoatfields showed the beginning of the ovi-
position period.

Indiana. C. Benton (April 25): Examination m&de in a heavily infested
field of wheat near Delphi on April 13,showed 88-percent pupation,
with 1 percent of the flies emerged. No eggs or larvae were found on
that date. On April 23, 90 percent of.the puparia were empty, the
flies having emerged. An egg count in wheat showed 92 percent of culms
infested, with an average of 18 unhatched eggs cper culm; a larval count
showed 84 percent of culms infested, with an average of 10 small larvae
per culm.

Kansas. H. R. Bryson (April 14): Adults were reported flying at Man-
hattan on April 14. They were observed by R. H. Painter.

J. R. Horton (April 16): The hessian fly.has demonstrated very
good ability to withstand unseasonably low temperature in the pupal
stage. On April 7 to 9 a population, of which 35 to 50 percent were
in the pupal stage, was subjected to ground-surface tempenratures of
30 F. for 40 hours and 280 for 10 hours more. The extent of mortality
resulting has not been determined, but as late as April 16 it shows no
striking increase above normal.

CHITICH BUG (Blissus leucopiterus Say)

Indiana. C. Benton (April 25): Migration from winter ouartors was slow
and gradual during April, many bugs still remaining in clumps of bunch
grass. Ex:aminmtion on April 14 of 5 winter wheatfields, totaling 182
acres, and one ryefield of 27 acros showed only 2 bugs, both concealed
in pieces of cornstalk. These fields situated near bunch-grass areas
are known to be rather heavily infested. Casual observations made in
winter wheat since Airil 12 show light infestation, evidently due to
minor flights. April weather has been cool, with frequent rains, but
even on several days of bright osunshine, with. air temperatures in the
901s, examination in infested clump grasses showed exposed chinch bugs









still with the tendency to hide, characteristic of the bugs
earlier in the season.
The first noticeable flight of the bugs and the first mating in the
field was observed on April 25, with the air temperature at 72Q

Illinois. W. P. Flint (April 20): Chinch bugs apparently came through the
winter with a very low mortality. There has been some flight during
the last few days, but not all of the bugs are out of winter quarters.
Missouri. L. Haseman (April 25): Chinch bugs wore observed on the wing on
warm days throughout centralMissouri during the last 10 days.

GREEN BUG (Toxoptera graminum Rend.)

Oklahoma. C. F. Stiles (April 30): Green bugs are dana.inj w:heat in parts
of Harmon emand Greor Counties.

Texas. F. L. Thonas (April): Report of damage to .-hc!t by the green bug
in Hale County on March 26; also in Floyd County on April 5.

CORN

CORN AR WORM (Heliothis obsoleta F.)

I.iw Jersey. F. F. Dicke (April): The survival of pupae in cages in the
later part of March was soriewhat higher than in 1937 (26.5 percent, as
compared to 20.5 percent). In a field examination 13.3 percent of the
pupae recovered were living. Above-normal precipitation late in the
summer and early in the fall resulted in considerable mortality. Win-
ter temperatures at Morristown were about normal. The indications are
that early maturing sweet corn in the Burlington section in New Jersey
will be somewhat less infested than in 1937.

Virginia. F. F. Dicko (April): The survival of pupae in late March in
cages established in mid-Septeibcr, was slightly higher than in simi-
lar cac..-s in 1937 (29.5 percent, as compared to 24.5 percent). In
field examinations the survival was found to be someswh-t lower than in
1937 (27.3 percent, as compared to 37.0 percent). The heavy rainfall
late in the summer and early in the fall of 1937 caused considerable
mortality of pupae in the field. The moisture content of the soil was
high throughout the fall and winter, a condition unfavorable for
successful hibernation. Temperaturcs wore above normal from December
to March. With normal temperatures and precipitation in May and June,
it is believed that the ear worm will probably be somewhat less abun-
dant in northern Virginia than in 1937.

Georgia. T. L. Bisscll (April): Crged female moths are laying c,~s in
large numbers at Experiment. The first v.'ore obtained the night of
April 26.

Ohio. F. F. Dicke (April): The pupal survival in cages the last week of
March was 10.5 percent, as compared to 9 percent in 1937, when moth
emergence in cages was first recorded at Marietta. The temperatures







- 99 -


at Marietta were somewhat lower during the winter of 1937-38 than during
that of 1936-37; however, they were above normal. Precipitation was
below normal between October and March. With normal temperatures ana
precipitation in May and June, indications arc that the insect will be
troublesome in early tomatoes and early maturing cweet corn in the Mar-
ietta section.

Georgia. T. L. Bissoll (April 18): One male, the first specimen of the
season, came to a light trap on April 17 at Experiment, in the central
part of the State.

Florida. J. R. Watson (April 23): Complaints are beginning to come in
of the depredations of the corn ear worm working as a budworm in all
parts of the State.

Kansas. J. R. Horton (April 16): For the first time the corn ear worn
succeeded in passing the winter in soil cages operated for 4 success-
ive years. It wintered over in the pupal stage, 6 percent of 200
worms surviving on April 2. The condition of soil and the depth of
pupation are about as usual. The winter was mild, except in December
when tho.official temperature dropped 1.00 below normal; in January
and February it was 4.5 above normal.

Utah. H. E. Dorst (April 23): Winter survival of pupae from overwintering
cages examined on April 21 shows a 17-percent survival, as compared to
65 percent from cases examined the first part of March. No survival
was observed in 1937.

EUROPEANT CORNB BORER (pyrausta nubilalis Hbn.)

Now Jersey. J. B. Schmitt (April 12): Surveys indicate that less than
5 percent of the overwintering larvae were destroyed by winter condi-
tions. Pupation is now in progress. The first pupae were found in
South Jorsey on April 12.

C. A. Clark (April 23): Spring pupation of the European corn
borer is about 2 weeks earlier than usual, owing to very warm weather
and suffiiont rainfall. Counts indicated from 15- to 25-percent
pupation in Burlington and Monmouth Counties by April 22.

Virginia. H. G. Walker and L. D. Anderson (April 26): A large percentage
of the overwintering larvae in an out-door cage at the Virginia Truck
Experiment Station have pupated and the moths have been emerging for
several days.

ALgULA

ALFALFA WEEVIL (Hypera postica Gyll.)

Utah. C. J. Sorenson (April 22): Moderately abundant in alfalfa in Cache
County.

California. A. E. Iichelbacher (April 20): There was only one field in







- 100 -


the San Joaquin Valley injured by the alfalfa weevil and this would
not be classed as economic damage. The average number of larvae
collected ner 100 swoops of an insect not in this field exceed 3,000.
The highest larval populations in other fields wore seldom more than
500 and in many fields the count did not exceed 100 per 100 sweeps of
a net. The hi-host average larval count per 100 sweeps was 89 at
Pleasnnton on April 17, and on the same day in the San Francisco Bay
area larval counts in fields not cut were from 49 to 476 per.100
sweeps. Parasitization of large larvae by Bathyplectos in different
fields in San Joaquin Valley on April 8 ranged from -14 to 76-percent.
At Pleasanton 96 percent of the largo larvae were parasitized on
April 6. In the San Francisco .Bay area parasitization ranged from
87 to 91 percent.

PEA APHID (Illinoia -pisi Kltb.)

Now Jersey. J. B. Schmitt (March): This aphid was found reproducing on
alfalfa the la1t week in M.-rch and is still reproducing.

Delaware. L. A. Stearns (April 23): Because of the unusually early season,
pc-L aphids are appearing in considecrable abundance in Sixessex County.

Virginia. H. G. Walker and L. D. Anderson (April 26): Many alfalfa fields
are rather heavily infested. Although they are not nearly as abmun-
dant as last year, these aphids are present in many of the pea fields.
Indications arc that most of the garden peas in Norfolk and Princess
SAnne Counties will esc.io serious injury. However, a few of the pea
fields on the Eastern Shore of Virginia are becoming rather heavily
infested and at least two of the larger canners have started control
operations.

Louisiana. C. 0. Eddy (April): Those insects appea-r in small numbers in
southern Louisiana but are ab'i.1.:.>r.t in the northern part of the State.

Kentucky. W. A. Price (April 27): The aphid is abundant on alfalfa at
Princeton and H'.'-.'rson in western Kentucky.

Wisconsin. J. E. Dudley, Jr. (April 19): The first anphid,; .'an adult stem-
mother, was found near MI-7.ison on April 4. This aijlid must havo hatch-
ed the first of April or before. Alfalfa w?. looked over twice weekly
since the midclc of March but esgs .vcre very scarce last fall.
Kansas. H. R. Bryson (April 25): Some pea aphids arc present in theP
State but are not causing damge.

Utah. G. F. Knoowlton (April 3): First-, second-, and third-instar aphids
and eg::s were found in a gravelly, west-sloping alfalfa field at Mill
Crook, in Salt Lake County. (April 21): A mature stem-mother, and
first- to fourth- instar nymphs of the second generation, some with
well-developed- wing pads, were found on alfalfa and sweetclo*Vcr at
Willara, Ogdcen, and near Prove. (April 25): A few winged and mature
sccond-:oncration apterous pea aphids are now present on alfalfa, In the
Payson-Benjar.in area of Utah County these insects arc particularly
abundant for this c..rly in the season.






- 101 -


C. J. Sorcnson (April 22): Pea aphids are very -bbundant in alfalfa
fields at Moab.

Washing-ton. R. D. Eichmann (April 2): Populations nearly stationary
duri..7 the last month on hay-meadaw alfalfa in the southeastern part
of the State. Very few are found on erosion-control alfalfa on higher
ground.

Oregon. M. M. Roehor and L. P. Rockwood (April 19): The long w=rm fall
of 1937 in the Willamotte Valley, following sufficient precipitation
to germinate self-sown and early fall-sown annual legumes, and a mild,
exceptionally wet winter were favorable to the winter survival of
viviparous forms. A wet, cold March delayed the spring build-up of
aphids until the first week of April. Since then a rapid increase :is
noted in several fields of vetch and Austrian winter field peas seeded
in September and early in October.. Fields seeded after October 25 at a
distance from earlier seeded annual legumes or from volunteer are free
from infestation., but sone migration into these fields is expected soon.
The only natural enemies present in appreciable numbers arc the two
species of fun-i Entomophthora aphidis and Empusa planchoniana, espec-
ially the former.

California. E. 0. Essig (April): Theo pea aphid, has been very b.-:nt..'nt in
the alfalfa fields of central and southern California since April 1. It
is especially numerous in the Antelope Valley near Lanca.ster.

COWPEA APHID (Aphis mcdicaginis Koch)

Arizona. C. D, Lebert (April 21): An extremely heavy infest:2tion of the
alfalfa or comwpoa aphid was observed in a 30-acre field of alfalfa
northwest of Phoenix. The alfalfa stems were bent over from the weight
of these pests.

CLOVMR

Maryland. E. N. Cory (April 19): This pest was reported from Ellicott
City attacking clover.

Kentuc-ky. W. A. Price (April 27): This weevil did some damage to clover
and alfalfa in the western part of the State.

Kansas. H. R. Bryson (April 13): The clover leaf weevil has been reported
as infesting alfalfa fields at Frcd.'nia.

Idaho. R. W. Haegele (April 19): This 7Ecv-il is much more abundant in
the southwestern part of the State than usual and in numerous areas is
damaging the early growth of alfalfa. Other outbreaks have been obser-
ved in springs following mild winters.

F. H. Shirck (April 15): Larvae are feeding in crowns of alfalfa
plants at Parma, in southwestern Idaho, thus preventin,- new growth.







- 102 -


Iiio is accentuated by the recent, cool weather, which has held alfalfa
from making normal growth. '

Utah. G. F. Knowlton (April 16): Adults were observed at Hooper.

C. J. Sorenson (April 22): Larvae were moderately abundant at
Hyde Park and Smithfield, Cache County. Two overwintering adults also

Georgia. T. L. Bissell (A-ril 14): Beginning March 19, frequent examina-
tions of vetch at Experimient, in central Geor.giao have yielde, .small
nurberf of c. 's, and. on that date one snail caterpillar was found. On
Ap-ril l4 it mn-tured to a moth. Moths were cor.imon at light traps and
around buildin.gs from December to March, inclusive.

STi'.VBZLPY RTITTWORI'v (Cnoplhasie. longana Haw.)

Oregon. D. C. Mote (April 27): First- and second-in-star larvae have been
abuncedant on vetch and clover at :Io.int Angel, Marion County, in north-
western Oregon, since the first of the month.

SUGAaRC-AE

SUGARCA3E IORSR (Diiatraoa saccharalis F.)

Louisiana. B. A. Osterberger (April 20)1 In Saint John the Baptist, As-
cension, and Est Baton Rouge Parishes the efrly spring weather was very
favorable for the early borer emer-gence, with indications of a very
early first generation. The first-generation -larval sta;e wr reduced
by frost an. low teniq0rftures accompanied by vind c'nd rain. in Aplril.
'.. ;s are being collected but to date no Tric' ogr-tnr a have boon taken.

FRUIT INSECTS


CALIFOITIA TENT CATERPILLAR (Milacosoma californica Pack.)

California. F. H. Vynore (April 19): Heavy infestation noticed of
the California tent caterpillar and a few colonies of M. disstria
Hbn. on prune and cherry trees in the orchards of the Asti Colony,
between Clovordale and Geyserville. From 12 to 15 colonies of
caterpillars were seen on many of the trees. Not a great deal of
d.ama.ge was apparent at that time, but most of the caterpillars
were in the second instar, so if nothing is done to prevent
feeding, a gre-t deal of da-iano will result.

LEF CRUIPLER (Mineola indigenclla Zell.)

Texas. F. L. Thomas (April 6): M.. indigenolla was found at El Campo
in Wharton County, on April U, on plum trees.

TARISiMD PLATT BUG (Lygus pratensis L.)

respectively. This is the result of a very mild winterr, the mini-
mum temperature having booeen 17 F.

SCUPJY SCALE (Chjonaspis furfura Fitch)

Connecticut. E. P. Felt (April 23): The scurfy bark louse was ex:treme-
ly abundant on an apple tree at Stamford.

Hatching' is expected to start about May 5. Pupation under rough
bark had reached only 33 percent by April-23.

Illinois. W. P. Flint (April 20): Survival very high. Pupation is
general in the southern part of the State. 1To adults have been ob-
served to date.

M1issouri. L. Hasoman (April 22): P'p-ttion has been under way since the
middle of the month, with 15 percent of the larvae in the pupal
stage in our breeding sticks in southwestern Missouri. At Columbia
some of the brecdi-.-cage material is showi:L:: nearly 30 percent pu-
pation, but examination at Columbia on April 22 showed the over-
wintering ''r.-i on the tree trunks still in the larval stage.

field on April 5; at present about one-third of the hibernating
larvae have pupated.

Kansas. H. P. Bryson (April 23): Codling moth is reported to be more
abundant in northeastern Iansas than for several years.

Washington. H. A. Others (April 5): Winter mortality at Yakima has
beeoon negligible owing to mild temperatures.

grain aphids were observed hatching the last week in March and the
first week in April in the lower Hudson River Valley and also
along the lake. A few specimens of these species, together with
the rosy aphid, were observed at Ithaca on Marc` 31. The rosy
aphid, although later, was being observed generally by the middle
of tho nonth.

Pennsylvania. H. E. Hodgkiss (April 19): Late-hatching aphids, -ostly
the rosy apple aphid, were killed in considerable nunbcrs by. freez-
in-- temperatures. The earlier individuals were plentiful enough to
cause considerable da:a-reo to apples.

Indiana. L. F. Stciner (April 25): The rosy aphid is as abundant in
southwestern Indiana as ever before observed, according to. n1uncros-.
growers. Serious injury is anticipated.

TERIPS iThysanoptera)

Pcnnsylvani.. H. E. Hodgkiss (April 19), Thrips adults are very abund-
ant on apple buds in sone orchards.

PEACH

ORIEITTAL FRUIT IOTH (Grapholitha molesta Busck)

Delaware. L. A. Steamrns (April 23): Between 8O and 90 percent of the
overwintering' larvae have pupated on this date. Peaches are approach-
ing the shuck, stage.\

South Carolina. O'. L. Cartwright (April 2$): Infestation is moderate
to hcav:, in peoach orch-rds in the south-central section. The pest
is earlier than usual in its activities.

Georgia. C. H. Alden (April l1): Fruit noth caught on April l1 at Cor-
nelia. No eog laying or twig injury has been noted to date in this
section.

0,. Snnpp (April 22): Apractically naturod larva was found
in a peach drop on pril 9 at Fort Valley. 'The first pc-ch 'twig
injury w'r:s noticed on April 13. The larvwo in these twigs wore
fro: one-fourth to one-third grovmwn. The infestation is light.

:.ichi.'--n. R. -Hutson (April 25): The oriental fruit moth had approxi-
r;.tely pupatod 50 poirccnt on March 25 at St. Joseph, "and on April
11 fro- 30 to 50 percent at South Haven..

PEAC:': BO_2R (Conopia exitiosa Say)

Illinois. 0. I. Snapp (April 13): "During the ea-ininatiori, of 'peach trees
at Carboondale, southern Illinois, 53 p-ach'borers wore re-ovcd
front one large 10-ycar-old pcr. c" tree. This is believed to be a re-
cord for the r.xicr of borers in one tree.

PLUH CURCULIO (Conotrachelus ncie'-Iar Est.)

Delaware. L. A. Stearns (April 20): The first curculio of the season
was collected by jarring in Sussex County on April 6, about 2 weeks
earlier than usual. They are appearing in about normal nunbcrs.

Virginia. A. H. W1oodside (April 20): Plun curculio beetles are present
in very large numbers in th'e Crozet peach orchards. More than 330
beetles were jarred front 20 trees in the Zirklc orchard on April
13. This is the heaviest concentration I have observed.

Georgia. C. H. Alden (April 20): Peak c inergonce from hibernating quar-
ters occurred on arch 24 at Cornelia, when 130 wore caught by jar-
ring 20 largro poach trees.






- 109 -


0. I. Snapp (April 22): One nearly full-grown lirv-i. was ob-
served in a green poach a# Fort Valley, central Georgia, on April
8." Full-grown larvae wore recovered from peach drops in trays on
April 13, which is 3 weeks earlier than last year, and the peak of
larval emergence from peach drops occurred on April 19. Conditions
in peach orchards were favorable for the matured larvae to enter
the soil. Keavy rains beat peach drops into the soil and made the
soil wet for a considerable depth. This facilitated the entrance
of larvae into the soil and the construction of their soil ceils.
The infestation is now considered lighter than that of an avcr7L.-e
year, which is largely attributed to the light infestation last
year and the lighter than usual carry-over of adult beetles. It
is probable that at least the Elberta peaches in Georgia will be
subjected to a second brood of the curculio this year. The peakc of
the Hiley drop occurred on April 15, and the peak of the Elberta
drop on April 20. The drop was unusually heavy this yepar; but the
curculio infestation in the drop was light.

Mississippi. H. C. Peets (April 25): Zamage in sone peach orchards in
Lincoln County recently reported.

Tennessee. L. B. Scott (April 26): The infestation appears to 'be about
normal in north-central Tennessee. Da:aed peaches are very common.

was reported from Cadiz, and specimens were jarred from plun trees
at Hendoerson on April 18. Egg punctures were observed at Lexington
on April 25.

BLACK PEACH APHID (Anuraphis persicao-niger Smith)

Virginia. W. J. Schoene (April 20): The black peach aphid has been re-
ported over a wide area.

South Carolina. W. C. Nettles and F. Sherman (April 28): Black: peacch

the western part of the State.

LEA2:OPP:?.S (Cicadcllidae)

Virginia. A. H. Woodside (April 20): Loafhoppers are very numerous on
peach trees at Crozet and Tinberville. The most common specie is
Erythroncura obliqua(Say),but there are a few specimens of E. hartii
(Gill) and E. lawsoniana 3ak. E. lawvsoniana is fairly comon on apple,
together with a few individuals of the other two species.

PEAR

PEAR PSYLLA (Psyllia pyricola Focrst.)

most desert breeding areas of northern Utah is appro::i-:-.ntc.ly on.c-
fifth higher than last year. Winter survival has been high, but
the fall population of 1937 was reduced because of poor host plant
condition. Some survival has been observed in the agricultural
area. First-instar nymphs were first observed on April 22, as

captured. The description of the insect by the growers, together
with the numerous runs, seems to indicate that the infestation is
of mole crickets, which have not hitherto been found in seedbeds
here. Last year the first commercial attack was recorded by A. I.
Bourne in lassachusetts on potatoes. (See I. P. S. Bull. Vol. 17,

has been rather light because of the unfavorable weather conditions.
A rather high survival of weevils is indicated by activity in hiber-
nation cazcs, (April 30):, Weevils arc becoming abunant and in
some fields over 600 per acre have been found.

Florida. C. S. Rude (April 30): Only 2 few weevils have been found on
cotton in the vicinity of Gaincsville, and a few have been reported
from Madison County. .

Mississippi. E. W. Dunnamd (April 23): At Stoneville no weevils have
beeoon observed this year. None was reported on this date in 1936
or 1937, "out one was seen on April 19, 1935.

Louisiana. R. C. Gaines (April 30): No field examinations have been
made at Tallulah but more weevils are beinr caught on flight screens
than in April 1936 or 1937, and a high survival is indicated.

Texas. F. L. Thomas (April 22): Theo usual extensive survival in the
lower Rio Grande Valley did not occur this spring, because of the








- 123 -


fall clean-up of cotton fields. Severe early da-ine is therefore
not anticipated, despite the fact that the winter has bceon mild
and some weevils have already been found on cotton in the field.
Survival to date in central Texas is 0.7 percent, about normal for
this month.

F. L. Thomas (April 29): Boll weevil.1 emergence has been a
little morc than 2 percent and is less than -vcra-e in central
Texas. Normally, half of the weevils that survive the winter have
moved to the fields in search of cotton before May 1. This year's
figures indicate that the emergence will be below normal.

R. W. Moreland (April 3C); Weevils h&va been fairly active
in cages at College Station since the rains of April 25 and 26, but
none has been observed in the field.

X. P. Ewing, Port Lavaca. (April 9): Observqtions during the
first week of April showed continued weevil activity in stubble
cotton and punctured squares wore becoming numerous.

COTTO: FLEA HOPPER (Psallus seriatus Rout.)

Louisiana. K. C. Gaines (April 30): At Tallulah flea hoppers have
been taken in sweeping evening primrose, but they are not as
abundant as at this time last year.

Texas. F. L. Thomas (April 22): In central Texas the emergence of flea
hoppers the latter part of March was, with two exceptions, the
highest since 1920. During the first 2 weeks in April it was
higher than in 1935, a flea hopper year, indicating that early
cotton would have boeen,.subjcct to dr-a;'o had it not been destr.ycd.
Present indications arc that flea hopper damage in central Texas
nay be reduced because of the lateness of the cotton crop. In
northern Texas damage is not expected to be so severe as in 1937,
as records show flea hoppers to have been only half as numerous in
the fall of 1937 as in 1936. Such records constitute a good index
of the numbers that will be present the following spring.

F. L. Thomas (April 29): During the last 2 weeks cotton flea
hoppers' appear to have been delayed in hatchin,-. With two excep-
tions the hatch since April 15 has been the lo-rest.for 12 years.
Ordinarily g3 percent of the hatch occurs between M'arch 15 -nd
Mlay 1. This yc--r the nuaibcrs hatched during the 6-wock period
have been about three-fourths of normal. Late-hatched flea hoppers
usually find their preferred weed-host plants in a desirable stage
of growth, so that the curtonary early spring dispersal or miira-
tion becomes unnecessary and fewer of the insects reach the cotton
fields. Both adults and young have been found in Dallas County,
and hatching has begun in weeds collected from four counties and
caged.

K. P. Ewing (April 23): At Port Lavaca emergence from the
overwintering eogs in hibernation cages has been very low, only
about one-eighth as groat as in the previous 4 years. The move-
ment to the fields, as indicated by the catch on flight screens,
has been about three times as great as during the sare period in
the last three years. The heavy.migration to the fields, despite
low omncr.-- nce, was probably due to the very warm and favorable
weather until April 6, that was ideal for the maturity bf the
nyphs hatching In'Fehrmary and March. (April 30): Heavy emer-
,-ence from hibernation cages since the rains on April 25. The
peak of emergence is much later this year than ever before re-
corded,in southern Texas. ,

Arizona. W. A. Stevenson (April 16): The first nymphs of cotton flea
hoppers were found on snail croton plants near Rillito, in Pima
County. Plants were not numerous but hoppers were found on practi-
cally every one..

TIMIPS (Thysanop tora)

Louisiana. C. 0. Eddy (April): The flower thrips has been reported to
be unusually a-bundant. No thrips djaeo on cotton as yet.

Tex:as. F. L. Thomas (Aril 22); Thrips nu:-.cr'-,us in most cotton fields
of the lower Rio Gri.nde Valley, where dry weather has occurred.
Sufficient dor-a.'c to delay development of plants has resulted in
some fields.

K. P. Ewing (April 23): Report received from C. D. Dickey
that onion thrips (Thrips tabaci Lind.) are causing great damage
to cotton in the dry-land farming section of the lower Rio Grande
Valley, particularly near Raymondvillc. A largo acreae of onions
was .7ro.-nI and the thrips transferred from the mature onions to cotton.

BOLLC'C..! (Heliothis obsoleta 7.)

Texas. R. W7. loroland (April 2): At College Station no eggs have been
found to date on plants other than alfalfa. (April 9): The first
oegs were found on corn during the week. (April 16): Several
moths energed in hiler--.ation cages during the week. (April 30):
E_.-s at the rate of 4 per 100 plants wore found on corn on April 25,
the first .egJs found on corn since the rains on April 9 and 10.
EIcrence from hibernation cages averaged 22.5 percent, the highest
emergence ever recorded at this date.

K. P. Ewing (April 23): At Port Lavaca numerous bluebonnet
plants were examined for eggs during the week, with negative results.

PI::. BOLLW70P1? (Poctinoh-)r-r gossypiolla Saund. )

Texas. L. 7. Noble (April 23): Practically all cotton is up to a good
stand in the Big Bond area and shows no ill effects of the cold
wave on the gth and 9th. At Presidio pink bollworm moth emer-
gence in hibernation cnges continues to be exceptionally heavy, as
compared to that in other years.

COTTOILT LEAF WOiM (Alabama argillacoa Hbn.)

Texas. K. P. Ewing (::ay 2): One leaf worm about one-third 7romr_ was
found in stubble cotton in Calhoun County. This is the earliest
observation 6f-first appearance since 1922. In 1936 the first ap-
pjearance was on Hay 5, whereas in 1937 the leaf worm was not
found until M't-- 27.

South Carolina. C. C. Nettles (April 26): Forest tent caterpillar is
present in extra largo numbers in the lower part of the State.
Evidently so;-e check on the abundance of the insect is not opera-
tin-, as there was a bad outbreak last year and a more serious one
this year. It is necessary to keep the windows of houses down to
prevent the insect from coming in, from 15 to 20 caterpillars having
often bocn found in 1 room. A letter from the county agent at
oalterboro states that the outbreak in that county is the worst
ever hard of; that last year they took the major part of the honey
crop by' defoliating black gun and tupelo trees; and that this year
in the northeast corner of the* county, near Cottagcvillo., several
species of oak, even blackjack, hi-nve been attacked and defoliated*--

the "Adirondack black-fly," during the last few years has mado its
appearance in unusual abundance about Ithaca and is fast becoming
a pest of first importance about homes, both in the city and

EYE G'JATS (Hippelates spp.)

Florida. J. T. BiChan (April 26): Eye gnats and sore eyes were re-
ported very troublesome in January, February, and March, at
Okeechobee, just north of the lake, and at all points around the
eastern and southern shores of the lake. There was not much
trouble with them at .oore Haven, toward the western side. Gnats
are said to be scarce throughout the low, flat country northwest
of Moore Haven until higher ground is reached about 12 milcs south
of Lake Placid. From this point northward along the Ridge to
Haines City, a great deal of trouble was reported every place with
gnats and sore eyes. They wore abundant enough to be bothersome
in school rooms. Sore eyes are said to be most prevalent in the
spring from Sebring south. Although trouble from gnats or sore
eyes was not reported at all points along the hi-wnay skirting the
east coast of Florida, an abundance of them was reported in truck
fields in southeastern Florida on the edge of the Everplades, only
a few miles inland. A status trap, located 3 or 4 miles inland
from Fort Pierce, indicated the presence of considerable nu'wbcrs of
gnats in that locality. Eye gnats were not abundant in the .area
