TIE MORE IMPORTANT RECORDS FOR MAY 1934

Early in May grasshoppers started hatching in the Great Plains region and by the end of the month the poisoning campaign, which is being carried on in cooperation with the States, was well under way.

Mormon cricket outbreaks were recorded from Ideaho, Montane, Wyoming, and Uti. Two outbreaks of the coulee cricket are occurring in limited. areas of Washington, one at Pasco, and the other near Wenatchee.

Heavy flights of the beet webworm and alfalfa webworm were recorded about the middle of the month from North Dakota, south to Kansas, and westward to Colorado.

The chinch bug outbreak has developed into what is probablythe most serious
outbreak in the past 50 years. The heavy drought over much of the chinch bug belt has prematurely dried the small grain and forced an earlier migration into the corn in some places.

The pea aphid was destructive over a wide area extending from the Gulf norhward to Nebraska and Wyoming.

The first adults of the codling moth were observed in the Hudson River Valley during the second week in May. They were observed in Delaware and Virginia during the first week in May. In the West the first moths were observed during the middle of April in Colorado and the Pacific Northwest, and in Kansas during the first week in May. The peak of emergence had practically passed in all sections by the end of May.

One of the most severe outbreaks. of the grape leafhopper ever recorded in the Napa and San Joaquin Valleys of California was reported this year.

Spring counts of Japanese beetle larvae indicate that this insect sufi red no abnormal winter mortality during the severe winter of 1933-34.

Single individuals of Brood VIII of the periodical cicada were recorded from Maryland in the vicinity of Washington, D. C. These records are well without the normal range of this brood, although previous records indicate that scattered individuals have been found in this region.

During the last week in April Mexican bean beetle adults -ere first observed
in the eastern ?Virginia trucking section, and during the middle of May in Maryland. By the end of the month the insect was appearing in numbers i, tihe South Atlantic States.














SPECIAL REQUEST OF OUR COLLABORATORS

California. A. E. Michelbacher (May 22): On this date young nymphs
were found in fair numbers. The species is probably M. differentialis
Thos.

Canada. Daily Digest (May 28): It is estimated that about 48 percent

COULVE CRICKET (Peranabrus scabricollis Thom.)

Washington. E. J. Newcomer (May 18): Two rather severe outbreaks of the
coulee cricket have occurred this spring, one near Pasco, in Franklin
County, in the wheat.fields, and the other near Wenatchee, Chelan
County. With the cooperation of c'eounty agents and specialists 'from '
the State college, growers are making an effort to stop the invasion,

CUTWORMS (Noetuidae)

New Jersey. R. C. Burdette and B. F. Driggers (May 25): Cutworms have been
unusually abundant and have caused considerable damage to newly set
plants.

Illinois. W. P. Flint tMay 22): Damage from cu-tworms, mostly the claybacked*(Feltia gladiaria Morr.) have been reported in many cases from
spring-plowed clover and swdetclovdr ground. Fall-plowed round seems
to have almost completely escaped damage.

Temnesee. G. M. Bentley (May): Lycophotia -margaritosa saucia Hbn.,
Agrotis c-nigrum L., A. ypsilon Rott., and F. dicena Walk. are very
abundant.

Nebraska. M. H. Swenk (May 15): Inquiries concerning the control of cutworms were received during the first week in May from central and western Nebraska, especially from Greeley, Sherman, Garden, and Box Butte
Counties.

Utah. G. F. Knowlton (May 10): Gutworms have caused considerable injury
to tomato seedlings in the northern part of Davis County. Plants in
a few hotbeds have also been damaged.

California. S. Lockwood (May 1): During the latter part of April the
variegated cutworm (L. margaritosa Haw.), and an unidentified species damaged Valencia'oranges in one grove in Tulare County. Young wood and bloesoms for the 1935 crop were destroyed over about 10 acres and
later the worms ate the ripe fruit. From o4 half to two field boxes
per tree were destroyed.

BEET WEBWORM (Loxostege sticticalis L.)

Minnesota. A. G. Ruggles (May 29): Moths of the sugar-beet webworm have
been extremely abundant across the central part of the State.

North Dakota. J. A. Munro (May 6): Adults are moderately abundant at
dahpeton, Richland County, and at Fargo, Cas's County.

Nebraska. M. H. Swenk (May 15): Reports were received from Furnas and
Lineoln Counties the second week ip May of A great abundance of firskbrood moths in lawns and grasslands, presaging an outbreak in western.
Nebraska late in May .nd in June.






97





Colorado. G. M. List (May 26): Moths are flying in numbers sufficient to
indicate a normal infestation in'most of the sugar-beet areas. In some
of the plains areas in the eastern part of the State the infestation will be considerably heavier. Here the Russian thistle is one of the
important hosts.

ALFALFA WEBWORM (Loxostege commixtalis Walk.)
Kansas. H, R. Bryson (May 24): Moths of the alfalfa webworm (L. commixtalis) are reported as very abundant in pastures, grasslands, and weed
patches at Gretna, Phillips County, Garden City, Finney'County, Bird
City, Cheyenne County, and Hoxie, Sheridan County.

Colorado. G. M. List (May 26): The flight of moths in northern Colorado
was rather light this year. However, in the Arkansas Valley the moths
occurred in such numbers that the pest will undoubtedly be of considerable economic importance.

GARDEN WEBWORM (Loxostege similalis Guen.)

Iowa. C. J. Drake (May 28): Unusually large numbers of moths have been
found in alfalfa fields during the past week, indicating grave danger
of a serious webworm infestation in alfalfa.

VWHITE GRUBS (Phyllophaga spp.)

Vermont. H. L. Bailey (May 26): Adults are extremely abundant about
lights at Montpelier, Washington County.

Maryland. E. N. Cory (May 25): Adults are reported as injurious in Baltimore City and Baltimore.County.

The beetles are injuring 6ak trees acind EnglIsh walnut trees in PrinN
William County.

Pennsylvania. H. E. Hodgkiss (May 23): Adult emergence started in the
central counties on May 4; heavy statewide emergence at peak on May 21;
unusually heavy emergence. Records covering the past 16 years indicate that heavy emergence occurred in 1919, 1922, 1925, 1928, 1931, and
1934.

Ohio. T. H. Parks (May 24): May beetles have been unusually abundant,
flying about trees. Some reports of oak leaves being cut off'have bebn

Kentucky. W. C. Price (May 24): The first beetles of the season were observed on May 1. The flight was heavyabout Lexingto4 uitil May 18.
Foliage of many oak trees was badly damaged. Larvae have ruined many lawns at Paint Lick and Lancaster, Garrard County, and Lexington, Fayette County.

Wisconsin. C. L. Fluke (May 21): Adults of Brood C completely defoliated
oak trees in Lafayette, and Iowa Counties. They are less abundant in
surrounding counties.

South Dakota. H. C. Severn (May 9): Many requests have been received for
information on control of June beetles working on trees and bushes,
sometimes completely defoliating theme

Kansas, H. R. Bryson. (May 24): White grubs are reported injuring strawberries near Manhattan.

Alabama. J. M. Robinson (April 30): Brown June beetles are very abundant, eating pecan foliage at Brundidge, Pike County.

Nebraska. M. H. Swenk (May 21): May beetles are very abundant.

California. C. S. Morley, Kern County Agr. Comn. Monthly News Bull. (May 1):
Heavy, infestation in parts of the county. The beetles, hatched on uncultiveted lands and migrated to cultivated fields. Severe damage to
cotton and grapes has been reported. This is the first time serious
damage has been done by this pest in a number of years.


C E R E A L AN D F 0 R AB E C R 0 P IN.SECTS

WHEAT

CHINCH BUG (Blissus leucopterus Say)

Ohio. T. H. Parks (May 24): Bugs left their winter quarters and.were flying to small grain fields during the first week of May. We expect
serious damage to corn if the drought continues through June.

Illinois. W. P. Flint (May 22): The chinch bug situation is the worst
since 1887, and probably worse than at any time in the history of the










99


'State*. Young bugs are just beginning to hatch. Owing to the .large
.numbers of overwintering bugs and the severe droght, much small grain
has been killed by the old bugs. Unless heavy rains occur within the next 2 weeks, the chinch bug will destroy more than half of the smallgrain crop .

Michigan. R. Hutson (May 22): Chinch bugs are moderately abundant*

Minnesota. A.G. Ruggles (May 28): Chinch bugs are very abundant in
five townships in Goodhue County.

Iowa. C. J. Drake (May 28): The Rituation in Iowa is extremely serious,
many thousand fields of small grain having been badly injured o totally destroyed. The infestation is extremely heavy in the three most
southern tiers of counties.

Missouri. L. Baseman (May ?3): Adults are killing barley and oats in
places in central Missouri but doing little damage to wheat. This is
the worst outbreak in 50 years.

Nebraska. M. H. Swenk (May 15): Chinch bugs came out of hibernation in
great numbers in April and May and by the middle of May were concentrated chiefly in, the wheat and barley fields, where egg laying was in
progress. It is estimated that 30,000 Nebraska farms are threatened
with chinch bug injury in June.

Kansas. H. R. Bryson (May 24): Qhinch bugs are more abundant at Manhattan
than at any time since 1926-27. The adults made their last flight into
the wheat, barley, and oat fields on May 5 to 6. In fields where the
wheat is thin the old bugs are causing some injury to the plants retarded in growth by the dry weather. Nymphs are coming ou in large
numbers but most of the eggs have not yet hatched. Sorghums and corn have been retarded in germination and growth, which adds to the seriousness of the situation, as the young plants will be quite small when the
migration begins.

Oklahoma. C. F. Stiles (May 17): Chinch bugs are not so numerous as they
were at this time last year, and very.few :complaints have been received.

GREEN BUG (Toxoptera graminum Bond.) early
Mississippi. C. Lyle (May 23): Specimens were received/in May with a report that they were abundant on corn at Sarah, in Tate County.

Nebraska$ M. H. Swenk (May 15): The spring grain aphid was seriously injuring wpeat in southwestern Nebraska d eng the latter half of April.
Banner and Hftch'!ock Counties were mostheavily infested.

Kansas H. R. Bryson (May 24):.. Although the green bug caused, considerable
injury to wheat and oats during April and th& early part of JIay, the
amount of wheat destroyed was not as great as was anticipated. Recent









100



rains have enabled plants to recover if they were not injured too severely. Reports of injury this month have come from La Cygne, Lebo, Redfield, Coffeyville, Sedgwick, and Wilson.

Oklahoma. C. F. Stiles (May 17): The green bug infestation has been quite
severe throughout Noble County and in parts of Payne, Pawnee, Osage, Kay,
Grant, Garfield, Kingfisher, and Logan Counties, the heaviest infestation being in Noble County. A questionnaire was sent out by the county agent of Noble County and the returns show that 22,484 acres of wheat are
a total loss and 50,592 acres are damaged. *The oat crop has been destroyed on 21,840 acres and damaged on 27,000 acres more, which is quite a severe loss to this county. The infestation is at a standstill and
parasites are gaining rapidly.

GRAIN APHIDS (Aphiidae)

Oregon. L. P. Rockwood (May 16): Grain aphids, Macrosiphum granarium
Kby. and Rhopalosiphum prunifoliae Fitch, declined rapidly in April.
Moxt of this decline was due to an epidemic of the entomogenous fungus
Empusa aphidis, but this disease vwas aided in the final clean-up by
syrphid and coccinellid larvae.

A LEAFHOPPER (Dikraneura carneola Stal)

Idaho. R. W. Haegele (May 21): This insect is very common and, in many
wheat fields extremely abundant in Gem County. Damage was severe
enough in many fields to reduce yields.

RICE STINKBUG (Solubea pugnax Fab.),

Texas. F. L. Thomas (May 23): Unusually abundant in Franklin County,
destroying some fields of oats.

CORN

SUGARCANE BEETLE (Euetheola rugiceps Lec.)

Mississippi. C. Lyle (May 23): Growers at Eupora, Webster County, and
near Yazoo City, Yazoo County, have recently reported severe injury to
young corn.

Tennessee. G. M. Bentley (May): An outbreak of this species, together
with Ligyrus gibbosus DeG., was observed in corn at Shelbyville, Bedford County, on May 10.

SOUTHERN CORN ROOT v1ORM (Diabrotica duodecimpunctata Fab.)

Georgia. T. L. Bissel (May 26): The budworm is very ihjurins on corn at
Experiment, both on plots that had had a cover crop and on those without cover. First adults of new generation were observed on May 22.













Mississippi. C. Lyle (May 23): A stand of young corn on a farm at
Toomsuba, Lauderdale County, was ruined in spots by larvae late in
April. Injury was also reported recently by a grower at touis-ville,
Winston County.

FLEA BEETLES (HalticinaeY

Tennessee. G. M. Bentley (May): Epitrix cucumeris Harr. wa's noted on
young corn at Greenfield, May 10.

Iowa. H. E. Jacques (May 24): Corn flea beetles have been'a severe
pest in corn in Henry County, making replanting necessary in some fields.

Kansas. H. R. Bryson (May 24): Flea beetles caused considerable injury to
the leaves of young corn at the agronomy farm at Manhattan.

60RN EAR WORM (Heliothis obsoleta Fab.)

Florida. J. R. Watson (May 21): The corn ear worm is very abundant but no
more so than usual.

Alabama. J. M. Robinson (May 22): The corn ear worm is moderately abundant
"at Aiuburn; adults observed, and larvae seen on young corn.

SOD WEBWORM (Crambus sp.)

South Carolina. W. C. Nettles (May 24): Ihis insect was injuring cdrn in*
Chesterfield County and also "damaging yang'c otton in Oconee County.

Iowao C. J. Drake (May 28): Sod webworms are unusually abundant and widely distributed. Large numbers of worms have been found in many fields
in southern Iowa during the past 2 weeks.

ALFALFA

ALFALFA WEEVIL (Hypera postica Gyll.)

Utah. C. J. Sorenson (May'26): The alfalfa weevil is very abundant in
Cache, Box Elder, and Utah Counties.

Nevada. Geo. G. Schweis (May 28).:. On the whole, damage has been less than
for several years past. However,'in some section the damage was severe
enough to justify control measures. Some airplane dusting was done
near Reno with good results.

California. A. E. Michelbacher (May 22): The alfalfa weevil is rather
difficult to find throughout most of the Tracy area. Only in th6 region
about Vernalis could the pest be collected in any numbers. There in one field an average of 48 adults and 3 larvae were collected per 100
sweeps, while in another an average of 29 adults and 2 larvae were taken.








102



CLOVER LEAF WEEVIL (Hypera punctata Fab. )

Maryland. E. N. Cory (May 25): Clover leaf weevils are numerous in
Harford and Kent Counties.

PEA APHID (Illinoia pisi Kalt.)

Alabama. J. M. Robinson (May 22): The pea aphid is very abundant. It
has destroyed 20 :acres of Austrian peas at Vincent, Shelby County.

Mississippi. C. Lyle (May 23): Severe infestations of aphids were reported on English peas by growers at West, in Holmes County, on'May 19.

Nebraska. M.H. Swenk (May 15): During the period from April 11 to May
7 there was a severe outbreak in the alfalfa fields in southeastern
and southern Nebraska.' Alfalfa was so seriously injured that in
thousands of fields the first cutting of hay was lost. Myriads of larvae of Hippodamnia convergans Guer. were in the fields and by the
end of the first week in May had largely gained control of the aphid.

Kansas. H. R. Bryson (May 24): The pea aphid has been very abundant
in alfalfa in the eastern half of the State. The infestations were
quite general over the fields and the first crop was considerably injured. By May 7 practically all of the aphids had disappeared, owing
to the control effected by H. convergens.

Wyoming. C. L. Corkins (May 21): The pea aphid has done much damage
in southeastern Wyoming, but is now under fairly good control.

Colorado. G. M. List (May 26): The outbreak on alfalfa has subsided.
Control has been due largely to the work of Hi convergens.

Oregon. L. P. Rockwood (May 16): The aphid epidemic, which was at its
peak in vetch and Austrian pea fields late in March, has been reduced
below the average abundance for this season of the year. This reduction was initiated by an epidemic of the entomogenous fungus
Empusa aphidis, which killed more than 90 percent of the aphids. The
fungous disease reached its peak in early fall-sown vetch and pea fields
about April 10, and in latefall-sown and spring-sown fields late in
April. The few aphids surviving the disease were further reduced by predators,particularly the syrphids (Syrphus torvus 0. S., S. opinator 0. S.) and Lasiophthicue pyrastri L. Vetch and Austrian peas showed
some recovery.

A HARVESTER ANT (Pogonomyrmex occidentalis Cress.)

Nebraska. M. H. Swenk (May 15): The mound-building prairie ant was reported damaging alfalfa.in Dundy County the third week in April.

FRUIT INSECTS

APPLE

CODLING MOTH (Carpocapsa pomonella L.)

New York. N. Y. State Col. Agr. News Letter (May): The winter mortality
of larvae was high in many areas in the western New York fruit belt,
but low in the lake zone and in the Youngstown area in Niagara County.
Even in areas where the mortality was highest, there was a considerable
survival of larvae below the snow line. The first catch of moths in light traps in the Rome orchard at Geneva was 4 days earlier and nine
times heavier than the first catch in 1933. First adults observed in
Hudson River Valley on May 17; larvae and pupae in Ulster County, May 10,

Delaware. L. S. Stearns (May 22): Eighty percent of the overwintered
larvae had pujLated by May 19; first emergence of spring brood, May 7.

Pennsylvania. H. E. Hodgkiss (May 23): The following numbers of adults
were caught in bait pails in Franklin County on the dates indicated:
May 14, 14; May 15-18, none; May 19, 62; May 20, 372; May 21, 343.
H. N6 Worthley (May 28): The first moths emerged. on the night of
May 10, when the earliest varieties of apples were just ready for the
petal-fall spray. Abnormally high evening temperatures produced
heavy flight of moths on the evenings of May 19, 20, and 21, bait pails
averaging over 70 moths on the evening of May 20.

Virginia. W. Schoene (-May 23): Adults are very numerous in the
Roanoke district, where large numbers emerged between May 8 and 15.
Many worms were entering the apples on May 17, 18, and 19.

Georgia. Cc He Alden (May 21): The codling moth is scarce at Cornelia.
There has been very little egg laying byspring-brood moths.

Ohio. T. H. Parks (May 24): Emergence of adults began in Lawrence
County on May 5 and at Columbus on May 13, Wooster May 17, and Oak Harbor on May 20. Although not more than the normal number overwintered, the spring has been very favorable for egg laying.

Illinois, W. P. Flint (May 22): Conditions this spring have been highly
favorable to the codling moth, and first-brood adults have emerged in unusually large numbers and are more closely bunched than usual. The
peak of emergence occurred in southern Illinois about May 12.

Missouri. L. Haseman (May 23): The peak of emergence of first-brood codling moths is past in southern Missouri, In the central end northern parts of the State emergence reached its peak this week. Worms began
entering the apples about May 17.

Nebraska. M. H. Swenk (May ei): The codling moth is moderately abundant
in the southeastern part of the State.






lo4



Kansas. H. R. Bryson (May 24): Very abundant in Doniphan County, in northeastern Kansas, where the first moth was taken on May 7. First moths
were taken onl May 3 in the viciniy of Oxford, in the Arkansas River Valley.

Colorado. Geo. Me List (May 26): The codling moth mortality was very low during the winter. The season is bringing the moths out earlier than
we have ever recorded. At Grand Junqtion, Mesa County, the first moths
were taken in traps on April 15. By April 25 the catches indicated
that the peak of emergence of the spring-brood moths was approaching.
J. H. Newton reported that the first moths were taken in traps at Paonia,
Delta County, on April 21 and that a large number was taken during the last days of the month. In the Fort Collins district the first moths
were taken in traps on May 15 and large numbers were taken on May 20 and
21.

Idaho. Re W. Haegele (May 21): The codling moth is very abundant.
Worms have been entering fruit since about May 1 in the southwestern
part of Idaho*

Utah. C. Sorenson (May 26): The codling moth is very abundant in Cache,
Davis, and Utah Counties.

Washington. E. J. Newcomer (May 18): Temperatures have been more norml
in ashington during May than in April, and only slight injury has occurred to the host fruits, apples and pears. What my prove to be the
maximum emergence took place from May 10 to 14.

EASTERN TENT CATERPILLAR (Malacosoma americana Fab.)

Northeastern U.S. J. V. Schaffner, Jr., (May 19 25): On May 12 C. W.
Collins noted very heavy infestations in the northern part of Delaware
and the eastern part of Pennsylvania. The first hatching noted was on
April 17 at Woodstock, Conn., and also at Melrose, Mass. On April 21 5. F6. R. Holbrook examined 51 egg clusters in the field at Melrose and
found 50 of them hatching and 27 densely covered with larvae. Infestation is generally heavy throughout Massachusetts, the northeastern
part of Connecticut, and the southern parts of Vermont, New Hampshire, and Maine. Through the northeastern part of Vermont and the northern
part of New Hampshire the tents are very scarce, and one can travel
many miles without seeing any. At Lyme, N.H., some wild cherry trees
were examined and several egg clusters were found which had failed to
hatch.

Maine. H. B. Peirson (May 20): The eastern tent caterpillar overwintered
well. Hatchihg started April 30 at Augusta and was apparently normal.
Larvae are very abundant and from Waterville south are more abundant

this may cause the second brood to be light or mray prevent it entirely. The general infestation increased during the month and is
heavier than average. Peach drops are very wormy in many orchards, and the alarm of growers over the increased infestation is resulting
in more diligent enforcement of control measures.

FO REST AND SHADE TREE INSECTS

ASIATIC 3EETLE (Anomala orientalis Waterh.)

Connecticut. W. E. Dritton (May 23): Grubs from a number of premises in New
Haven and West Haven have been brought to the xperiment station this spring,
Evidently they survived the subzero temperatures of last winter.

New York. C. H. Valley (April): The survey diggings at Jericho show an average
of 14 larvae per square foot, which is about the same as in the spring of
1933. The range in abundance this spring has been from none to 77 grubs per
square foot. At Jericho there has been some spread in the known area of
heavy infestation, as another lawn showing about 1 acre of ruined turf was
brought to our attention this sprig. This lawn is located northwest of
Jericho and nearly a mile from the older infestations. In Westchester @ount3 the abundance in the older infested area in the southern part of the county, extendiang from New Rochelle and Mount Vernon on the south to White Plains on
the north, shows very little change from last year. This season additional






117


infestations in the vicinity of Ossining, where there is considerable lawn
destruction, were brought to our attention.

in New 7aven.

New York. C. H. Tadley (April): The survey diggings at Jericho show an average
of 29 Asiatic garden beetle larvae per square foot, with a range of 1 to 60.
This indicates that they are a little more numerous than in the spring of 1933. The beetle is apparently more numerous now at Locust Valley than at Jericho. During April new infestations were discovered at Syosset in the extreme eastern part of Nassau County and on the grounds of the New York
State School of Applied Agriculture, east of Farmingdale, in Suffolk County.
The Westchester and 3ronx County infestations are about the same as last
season, except that the infestation has become considerably heavier in the
vicinity of Yonkers. Lawns in the northern part of Yonikers are showing
sufficient injury to necessitate rebuilding.

JAPANESE DEETLE (Popillia japonica Newm.)

New Jersey. C. I adley (April): Winter mortality this year was no greater
than that of other years, despite the unusually low temperature of February.
A rather general reduction of the population, as compared with that represented at this tine last year, is indicated in the older established infestations. In the newer infestations an increase is indicated. As a result,
the population of the coming summer may be expected to be, in general, about
equal to that of last summer, with more or less striking regional or local
differences.

hackborry, elm, and unsprayed apple trees at Lawrence. There was considerable injury to elms, hackberry, and honey locust at Manhattan, despite the
fact that the trees were banded, as it was impossible to maintain sticky
bands during the entire period of emergence. Canker worms have also been
reported causing injury at Chanute, Scandia, and Oxford. At the latter place
they were reported to be very abundant on apple and maples.

FOREST TENT CATERPILLAR (Malacosoma disstria Irbn.)

Colorado. G. M. List (May 26): The forest tent caterpillar is occurring in
epidemic form in a number of localities, the heaviest infestation probably

J. A. Hyslop (May 22): An adult, the only one I have seen this year,
was collected near my home at Avenel (Silver Spring). A large colony of
Drood X is in the ground at this place and this may be an accelerated indivi
ual of that Drood.

DZEECH SCALE (Cryptococcus fagi Daer.)

Maine, New Ilampshire, Massachusetts. J. V. Schaffner, Jr. (Mlay 19): R. C. Drown
reports that in eastern Massachusetts and southern New :ampshire practically
no mortality can be attributed to the severe winter. A superficial examination in the vicinity of Liberty, Me., indicates practically complete mortality above
the snow line in certain sections, while in other nearby areas the insect does
not seen to have been much affected by the severe winter.

JUTNIPER AID CEDAR

JUNIPER VE7DWOR1M (Dichomeris marginellus Fab.)

Marylanid. G. S. Langford (May 25): On May 23 this insect was observed pupating
at College Park. This date of pupation compares favorably with that of
1931, when larvae pupated from May 14 to June 2. Considerable injury was
done to junipers during early spring, especially to Irish and Swedish juniper
Many junipers are heavily infested.

DEODAR 7WEEVIL (Pissodes deodarae Hopk.)

LARCH

LARCH CASE 3EAE. (Coleophora laricella Ibn.)

New England. J. V. Schaffner, Jr. (May 25): This case bearer seems to be present
on all larch trees throughout New England. The infestations, in general, are not quite as severe as last year. However, the trees in many areas, especially in Maine, are almost completely brown from the severe feeding.

Maine. H. D. Peirson (May 20): This insect suffered very little winter mortality.
Larvae have moved onto the foliage, which is beginning to show brown from the
effects of the feeding.

Vermont. H. L. Dailey (May 26): This insect is very abundant at Sharon, but
apparently the feeding was nearly over on May 23. General observation in
Essex County on May 24 indicated only slight infestation.

New York. H. E. Horsey (May): Caterpillars in overwintered cases were moving
onto new leaves on May 2 an. for about a week after that date. On May 23
considerable damage was to be found on American larch, fot which they seem
to show a preference. A number were observed on Dahurian larch (Larix amelini
japonica) and on Siberian larch (L. sibirica). The least infested are Japanese larch (L. kaenpferi) and European larch (L. decidua). The planting under observation contains trees from 20 to 70 feet in height. The damage
probably would be greater if the trees had not been sprayed in the early part
of the month. Several reports from western New York indicate that this insect
is becoming a serious pest on the larch.

OAK

INSECTS ATTACKING MAN AND

D 0 E S T I C ANIMALS

WINTR TICK (Dermacentor albipictus Pack.)

North Dakota. J. A. Munro (May 19): The ticks reported in the Insect Pest Survey
Dulletin vol. 14, no. 2, p. 62 (April 1934) have been determined by F. C.
