THE MORE IMPORTANT RECORDS FOR JU13, 1932

Over part of the Great Plains area where grasshoppers were destruc-
tive last year, wet weather has occasioned some disease among grasshoppers
and materially advanced crops and other vegetation to such an extent that
damage will undoubtedly be less severe than last year. In the northern
part of this area, however, the weather has been hot and dry and serious
damage is anticipated where control measures have not been possible.

The Mormon cricket appeared in outbreak numbers in southern Idaho.

The pale western cutworm is doing considerable damage in western North
Dakota and scattered localities throughout Montana.

Armyworm infestations are quite generally distributed over Iowa,
southeastern Nebraska, and eastern Kansas.

The Hessian fly and the chinch bug situations have not materially
changed since last month.

Sod webworms are reported as quite generally prevalent from the south-
ern Middle Atlantic States westward to Nebraska

The rose chafer is reported in destructive abundance throughout New
England, New York, Michigan, northern Indiana, and Nebraska.

There was no material increase in abundance of the more important
apple and peach insects.

A European leaf curling apple midge (Dasyneura mali Kieff.) is re-
corded from Massachusetts. This appears to be the first American record.

A cherry sawfly leaf miner (Profenusa collaris MacG.) is recorded
for the first time from the State of Michigan.

The vegetable weevil is recorded from 9 previously unrecorded counties
in Alabama and 1 county in Texas. This does not materially advance the
general distribution of this pest.

The larvae of a weevil (Phytonomus rumicis L.) was found in destructive
numbers on commercially grown sorrel in Connecticut. This European pest
was first recorded in this country in Iowa in 1917.

The Colorado potato beetle appears to be abnormally abundant over
the greater part of the Eastern States this year.

The Mexican bean beetle increased rapidly during the month and was
reported in destructive numbers throughout the greater part of its range.
This insect was found for the first time in Illinois this month.

The pea aphid is making decided inroads on the cannery pea crop in
Ohio, Michigan, and Wisconsin.

The pink boll worm has been discovered this spring in Florida at
Miami and extending south to Key West. The infested region is some 400
miles from comnTcrcial cotton plantings.

The European pine shoot moth is now in flight in New Enzlr.nd and is
appearing in increasingly destructive numbers in that region and in New
York State.

A Japanese weevil (Pseudocneorrhinnus setosus Roelofs) which was
first recorded in New Haven, Conn., in 1920, is this year proving to be
somewhat of a pest of privet and barberry.


THE MORE IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA, FOR JUNE, 1932.

The grasshopper situation is serious in the Prairie Privinces, par-
ticularly in southern and central Manitoba, where the worst outbreak in
mere than fifty years is reported over a wide territory. Wifdecsprend areas
are also affected in south and central Saskatchewan, but although the out-
break is severe it is lees intense than in Manitoba. The situation in
Alberta s much better than was anticipated, a general heavy downpour of
rain .-arly in May having caused a high mortality of the young npnphs. The
species involved throughout the affected territory are the lesser migra-
tory, two-striped,and clear-winged grasshoppers.

Over a lnrge part of Saskatchewan and Alberta, the -vale western cut-
worm is again in severe outbreak form, and is cousin., very serious crop
losses. The outbreak is considerLbl) more extensive than in 1931. The
army cutworm also has increased materially in the Prairie Provinces, out-
bre'tTs having occurred in rriny localities in southern Alberta and south-
western Saskatchewan, where important crop da re, usxu-lly mixed with p-ile
western cutworm damage, was effected. Army cutworm moths were present in
great n,.-,bers and have attracted much attention, not only in Alberta and
Saskatchewan, but also in southern M.nitoba, where the species is not a
*est. Another rpccies, the red-bncked cutw7orm;, is occurring over a wide
territory in the Prairie Provinces, but severe d.%mage has been done only
in localized areas, notably in M-nitoba.









-191-


Wireworrms caused severe damage to wheat in western Saskatchewan, and
to sugar beets, locally, in southern Alberta, this spring. Moisture con-
ditions were favourable to wireworms in the affected areas.

Moths of the beet webworm have been extremely abundant in Alberta,
Saskatchewar., and Manitoba, and very heavy and widespread outbreaks of the
larvae are indicated. Weeds such as lambs quarters and Russian thistle
are chiefly subject to attack, but the species is also a pest in gardens.

A large flight of June beetles (Phyllophaga anxia Lee.) occurred in
eastern Ontario, in late May and June, over an area of possibly 1,500
square miles. Heavy damage to crops by the resultant grubs is considered
probable in 1933.

Outbreaks of flea beetles, notably the potato flea beetle, are re-
ported from southern Ontario affecting potato, tobacco,and other plants.

Adults of the oriental fruit moth commenced emerging much later than
in 1931 in the Niagara district, Ontario. The first-brood infestation is
lighter than it has been in any spring since the species became of economic
importance as a peach pest in southern Ontario.

A serious outbreak of grape Icafhoppers developed in the Niagara
fruit district in Ontario.

The balsam bark louse, Dreyfusia piceae Ratz., continues to spread
slowly in southern New Brunswick and now extends up the St. John River
Valley a distance of a little more than 50 miles from the coast. This
insect occurs throughout Nova Scotia, where it is one of the most important
forest insect pests.

Heavy infestations of the western willow leaf beetle occurred over
wide areas in Saskatchewan and Alberta, resulting in severe defoliation of
poplar and willow in the affected territory.

In sections of southern Manitoba, several species of deciduous trees
have been completely or partially defoliated by the fall canker worm. The
outbreak of this insect in New Brunswick, which was moderate in 1931, has
intensified somewhat, and much defoliation of elm and basswood has occurred.

The larch case bearer continues in outbreak form over a large part of
eastern Canada and in many sections severely defoliated larch.

Ticks are reported as unusually abundant in wooded areas in parts of
Manitoba and Alberta, and sections of British Columbia. Several species
are involved. In addition to attacking wild and domestic livestock, cases
were reported, from Vancouver Island and coastal districts of British
Columbia, of ticks attaching themselves to humans.

A. E. Stene (June 23): A report came in today from one of
the islands in the Bay stating that grassho-opers were eating
heavily.

0. I. Snapp (June 16): Grasshoppers are more abundant than
usual around Fort Valley, damaging corn and other crops. It
has been necessary to use poisoned-bran bait in some cornfields.

A. Lutken (June 24): A farmer in Pickens County reported
millions of grasshoppers destroying cotton. Upon examination
about a dozen colonies of several hundred each were found.
Several hundred cotton plants had been destroyed. The grass-
hoppers were very small and the species was not determined.
reports of
J. J. Davis Y sRJ ierio/serious outbreaks have been re-
ceived, although / were reported abundant at Jasonville
June 14.

7. A. Price (June 25): Grasshopurers, mostly small nymphs,
arc moderately abundant in the bluegrass.

R. H. Pettit (June 22): Grasshoppers are very a.iun.2ant. The
species involved are Melanoplus mexicanus Sauss., Camnula p.l-
lucida Scudd., and '. femoratus Burm.

C. L. Flu-:e (June 24): Grasshonpers arc very abundant.

A. G. Ruggles (June 27): Grass'-ior'-,rs are very abundant; 46
counties being helped.

J. A. Munro (June 18): Grass-ho-r*:rs are a serious menace to
crops in many counties. The northeastern section of the State
is hardest hit. The insects are still win.less. There will
be tremendous loss of crops. (June 23): Fungus has caused
almost co-nlete destruction of 7rasshoopers in two sv-'ll areas
in Cass County-at Tower City, ond near F-ar'go. Yesterday near
Fargo what was an exceedingly heavy infestation of vour'rs
shoved nothing but the dead bodies of the insects clin,:ing
to the tops of weeds and small grains. Fully 95 per cent were
killed. The re-oort regardin' the other area stated tiat about
the same percentage had died. Poisoned bait had not been
snrc- at either place. Ap-narently all the hor-crs have com-
pleted hatching. About 5 per cent of the earliest 1htches have
become winged.

F. D. Butcher (June 13): More than 90 per cent of t'-e nymphs
of M. bivittatus Sy are out now and nearly as many of C.. "pel-
lucida, though they -.rr a bit later than the former. Have

found a few scattering pods of M. differc.ti lis Tins. -nd of
either M. femur-rubrum DoG. or M. mexicanus in which no hatch-
ing has occurred, but these species are scarce. (June 20):
Adult of C. pellucida and first adult of '. bivittatus.

C. J. Drake (June 22): The infestation is very heavy in
western Iowa. Although numerous and extremely heavy rains
have destroyed many young hoppers, the population in some
fields runs as high as 50 to 500 per square yard. In one small
field of oats in Pottawattamie County, A. D. 7orthington, DEx-
tension Entomologist, and the County Agent, estimated the popu-
lation to average around 2,000 per square yard. The first
adults of the 2-striped grasshop-cer were observed in barley
fields near Sioux City, Jrune 21. A few adults of '!. mexicanus
have been observed in Story, Harrison, and Pottawattamie Coun-
ties. M. differentialis is the most common and abundant spe-
cies, but hatching is not complete. The number of first-instar
nymphs of this s-oecies is increasing every day in the field.
Poisoned-bran mash is being scattered by many farmers in west-
ern and central Iowa. Several species of blister beetles are
just beginning to nocar in large numbers in Iowa.

L. Haseman (June 20): Grasshoppers are very abundant in
some districts but June rains are favoring crops.

M. H. Swenk (June 1 to 20): During the month the grasshop-oer
situation has developed principally along three lines: (1)
the continued hatching of eggs, (2) a great reduction in the
grasshopper population of the northern and northeastern heavily
infested counties by heavy rains and floods, and (3) an increase
in the grasshopper population in parts of western and especial-
ly southwestern iebraska. By June 1 eggs of the two-striped
grasshopper had largely hatched on the upland south slocpes,
but those on the north slopes, and those in the lower ground,
the latter chiefly of the differential grasshopper, were only
about 60 per cent hatched. Hatching has continued through June
to date, and at present probably not more than 10 to 15 cper cent
of the eggs of both species together, on the average, remain
unhatched. The largest number of unhatched eggs is to be found
in the western counties. Heavy beating rains during the nights
of May 24 and 25 over much of the heavily infested northeastern
area wore mentioned as destroying a part of the hatch of the
two-stri-oed grasshopper. Similar rains over this area on June
1, and on several dates subsequently, have reduced the grass-
ho-ooer population in this bi,3l y threatened district very.
materially, perhaps 50 per cent. But in parts of this area
still, and over a large section of western Nebraska where lit-
tle rain has fallen during May and June to date, grassho-opers
remain menacingly abundant locally and threaten serious crop
dam nge.

H. R. Bryson (June 24): Apparently grasshoppers are more
numerous in the vicinity of MTan2attan this season than last

season. Judging from the number of req.,ests for information re-
garding the formula for, mixing the poisoned bran mash, grasshom-
pers are quite numerous in a number of localities. Reports from
Hepler, Maoleton, Byers, Silver Lake, and Oneida indicate that
grasshoppers are a menace inr. those localities.

J. M. Robinson (June 20): Grasshowrers are very abundant in


C. Ly!e (June 23): M.ore than the usual number of complaints
have bec-n received recently. Specimecns did not accompany
these complaints. Cotton, soy beans, flower gardens, etc.,
were rep-orted attacked.
C. 'Takeland (June 24): Grasshoppers -re quite numerous in
B-'6.arm and Cassia Counties and are being fought by the use of
poisoned bran mash. They are also reported from more Coun-
t, as becoming numerous enough to warrant poisoning operations.

G. G. Schweis (June 21): Grasshoppers are very abundant in
western cevada. Vigorous control program is in progress.

C. F. Stiles (Juno 21): Grasshoppers are very numerous along
creek banks, fence rows, and in pasture lands in practically
all of southwestern nnd south-central Oklahoma. A number of
species arc present, but c'rhaps the most numerous are ML.femur-
rubr'-.n, nd M. differentinlis.

Agric. News Service, University of ItTovada, gric. D:t. Div.
(June 13): Large kills of grasshoppers have been reportLc5. by
farmers in various Darts of Lyon County.

A. G. Stephens (June 24): Grasshoopcrs are moderately abun-
dant in northeastern and central Vyoming.

G. F. K.iovlton (June 10): Grasshop'pers arc bccomi-i- very abun-
dant and seriously darmgina in the Ouray VIley, and are causing
:.7"e d'.i-a e in the Becrectt, .Tilson, ind south Ashlcy Valley sec-
tions of the Uintah Basin. The grassho-nper situation continues
to become more serious in parts of Millard County. (June 20):
Reports just received indicate that :rnss-'-.Dners are bcorming
dangerously abundant in parts of Salt Lakc Coumty, and at Kanarr-
ville, in Iron County. They are also abundant in parts of S&n-
-notc, Sevicr, Millord, and Toocle Counties.

Sierra foothills ne-ar BElirado.

Daily Digest, Press Service, Office of Information, U.S.D.A.,

hoppers so thick that they delayed a passenger train was reported
from southwestern *-a-itoba yesterday.

MORMON CRICKET (Anabrus simrolex Hald.)

C. Wakeland (June 24): Crickets were first discovered this
year when they were found making their way to agricultural land
on irrigation water out of the Fort Hall Canal. Traced to their
source it was found that they were migrating from range land on
the east side of the canal in very large numbers. Steps were
immediately taken by the residents of that section and canal
barriers erected and trenches dug. For three weeks volunteers
turned out in large numbers constructing hand-dug trenches, es-
timated to be at least 40 miles in length. On the bottoms
of these trenches pits were dug for trapping the crickets. As
long as soil was moist trenches proved to be almost entirely
effective but when the soil surface dried in some of the soil
types they could crawl up the sides freely and esca-oce. In the
fight that has been waged there have been literally hundreds
of thousands, possibly millions, of crickets killed, yet there
are countless hordes remaining. No great damr:e has been done
to cultivated crops, primarily, I believe, because of the cool,
moist weathc-r conditions and the abundance of succulent vege-
tation on their native rnnge. The first adults were found on
June 14. We have found, large bands of crickets in Bingham
County on the Indian Reservation, in Bonneville County in the
dry-farming area, and in Fremont County. Tw.o more outbreaks
were reported in Elmore and Ada Counties.

FIELD CRICKET (Gryllus assimilis Fab.)

J. A. Munro (June 18): Newly hatched nymphs of the common
black field cricket were noticed at Fargo during the first
week of June. Their abundance at this time indicates that they
will -orove a troublesome vest this season.


CUTWORMS (Noctuidae)


Wisconsin





North Dakota


E. L. Chambers and assistants (June): Cutworms were reported
as seriously damaging a wide variety of cro-os early in June.
The main center of infestation was in a band extending from
Marinette and Door Counties souathwestward to Crawford County,
with another area across the northwestern part of the State.

J. A. Munro (, y3l): Just had a telephone call from the
County Extension Agent at Williston stating that cutworms had
completely destroyed a 70-acre field of wheat near Williston,
Williams County. From his descri-otion I judged that they were
the pale western cutwonrm.(Porosagrotis orthogonia Morr.). The
County Extension Agent at McXenzie County also reports the
prevalence of this species. (June 18): Many reports of seri-
ous injury by the pale western cutworm have been received from
Mountrail, Williams, McKenzic, and other western counties. Few
reports of cutworm injury have been received from the eastern
part of the State.

H. C. Severin (Juxie 13>: Cutworm damage has been more severe
than usual in South Dakota this spring. Damage is letting up
some at present writing.

C. J. Drake (June 22): The variegated cutworm (Lycociotia
margaritosa Haw.) is extremely abundant in alfalfa fields and
doing a considerable amount of damage throughout a large por-
tion of Iowa.

H. R. Br-son (May 27): Report from Great Bend states that
the larvae of omio-ohilk noctuella D. & S. destroyed the new
growth of grass on 4 or 5 acres of native prairie sod.

M. H. Swenk (June 1 to 20): Along with the armyworm Cirohis
uni-ouncta Hav.. in the alfalfa fields, during the second week
in June, were considerable numbers of the variegated cut7orm
(L. margaritosa saucia ITbn.) in Lancaster, Johnson, and Pawnee
Counties, but apparently not extensively elsev'here in the
State. In some fields the second cutting of hay was eaten
back quite severely in these three counties.

G. M. Bentley (June 22): Black cutworms (A7retj --
Rott.)are moderately abundant.

A. L. Strand (June 21): The palevestern cutvworm, P. ortho-
gonia, occurred in outbreak numbers in scattered localities
throughout the State. In Valley County approximately 16,000
acres of griAn, mostly wheat, was destroyed.

CALIFOR"IA TORTOISE SHEIL (Aglais californica B3-v.)

2. 0. Sssig (Juno 13): The cater'illnrs have defoliated
several hundred acres of Ceanothus, which is a good cattle
feed, in the Sierras, chiefly at fro- 3,000 to 6,000 feet al-
titude, although the butterflies are now, found plentiful and
some caterpillars are evident as hiih as 8,000 feet. The butter-
flies occur in thousands in some areas along the American
River.

C. R. Willey (June 25): Thite grubs arc very abundant near
Richmond, Henrico County, and in adjoining counties; heavy in-
festations in Loudoun County.

7. P. Flint (June 15): Very heavy June beetle flight re-
ported from McHenry and Carroll Counties continued into June.
Defoliation of oak trees practically complete in areas af-
fected.

R. Hutson (June 11): June beetles are very numerous in Bat-
tle Creek, Clinton, Howell, KX!lamazoo, Monroe, Saginaw, and
Sault Ste. Marie.

E. L. Chambers and assistants (June): Severe defoliation by
adults and rtthcr large infestations of larvae were reported
from 11 counties in the southern and western -oarts of the State.

C. L. Fluke (June 24): Thite grubs are very abundaant. Adults
are very numerous in southwestern 7isconsin; they are now lay-
ing eggs.

C. J. Drake (June 22): June beetles, Brood A, are appearing
in large nuinbers in eastern and southern iowa:, and in many in-
stances trees are being defoliated. At Hampton a number of
trees were dusted by means of en airplane. A nursery man liv-
ing near the grove reports that many beetles have been killed.
During the past few years white grubs have caused heavy losses
in western and southern Iowa, particularly in Decatur and
Wayne Counties. Brood B destroyed :-,-'out 75 per cent of an
oat field near Marshalltol'n. The grubs stopped feeding and
migrated down deeper into the ground to form pupal cells about
three weeks earlier than Brood A did last spring.

:1. H. Swenk (June 1 to 20): White grubs are moderately abun-
dant and injurious in strawberry beds during the period here
covered, in an area from Douglas and Cass Counties west to
Hamilton County.


A 'WIRFO1M (Heteroderes laurentii Guer.)


K. L. Cockerham (June 15): Reports by farmers and produce
men of Bay Minette indicate that February and 7tarch planted
corn and s-ring-planted sna-o beans were very seriously damaged.
The species causing this damage wasn't nown, but it is pre-
sumed that it is H. lmre.ntili since that seems to be the pre-
dominating species of that section. On the above
date young larvae of this species were ozser7ed feeding on
late-planted corn at Foley. The larvae were so small, however,
that they will likely not affect the stand or do any consider-
able damage. Measurements of larvae collected indicated that

HESSIAIT FLY (Phytophaga destructor Say)

T. H. Parks (June): In southern and central counties the in-
festation has increased over last year. Not much damage has
been done, to the wheat as the infested straws are not broken
over though some fields average between 30 and 40 per cent of
the straws infested. The annual wheat insect survey is now in
progress..

SJ. J. Davis (June 27): Hessian fly is quite general over
the Btate with some sections, notably the southwest corner,
with very heavy infestation's. Early in June frequent reports
were received from central Indiana of noticeable fallen vheat.

J. H. Bigger (June 17): The Hessian fly is very abundant
over western Illinois. MAvny fields of wheat are not worth
cutting because of damage. It is easy to sec f-llen straws
while driving by the fields. Some fields are already plowed
under.

S. C. Chandler (June): Infestation in most fields examined
in.southern Illinois is heavy.

tion--an eastern area and a western area. Altogether 20 rcbras-
ka counties arc involved, either .'-.olly or in part .in the areas
of serious infestation. (June 20): The only nevw development
in the infestation since my report ofJ'. lis that the western
area of infr zt-tion has been found to extend from- north'..:estern
Buffalo County into eastern Ty'-v son County and south. western
Custer County. The infestation is ligh.t ovor this arc.--, a t:mpi..-
Cal field near Callaway, Custer County, showing only 27 tor cent

C. J. Drake (June 13): 'Jestern Iowa is ho-,vily infested.
These pests are doing considerable damage in a number of
fields of small grain. The infestation seems to extend from
Mills County to north of Sioux City, spreading eastward. In-
festation is pretty general over western Iowa. (June 22):
Thousands of acres of rye, whe-t, barley, and oats have been
totally destroyed. In a 900-acre field -of wheat in Harrison
County the farmer scattered poisoned bran, mash by means of
an airplane. In a number of instances arrnwerms have migrated
from small grain to adjoining, fields of corn. In Joodbury
County the county agent estin;.ted that the worms destroyed a
field or two of small grain on 500 different farms. The worms
are just beginning to appear in the central portion of the
State. Along the Missouri Biver most of the worms have pu-
pated. '

M. H. Swenk (June 20):', As a result of the unusual abundance
of moths flying in southeastern Nebrask:a during the third

irregularly. Pupation is beginning at Columbia.

M. H. Swenk (April 20 to June 1): The first pupation of over-
wintering larvae occurred on April 15, with some pupation nearly
every day since. The peak of pupation was reached on '.ay 6. On
June 1 a total of 445 out of 700 larvae have pupated. The first
adult moth was caught in our bait traps on May 6. From that
night to May 25 moths have been caught in the bait traps every
night except six. The largest catch to date in our six bait
traps occurred on the night of May 20, when 79 were ca::.-ht.
The first emergence of adult moths from 700 overwintering larvae
in the insectar, occurred on May 12. There has been some emer-
gence each day since, except during the cool period on May 16
and 17. The peak of emergence in the insectary to date was on
May 24. Egg laying started on May 18, since that date has
steadily increased, and up to date 2,026 eggs have been laid.

E. J. Newcomer (June 22): Much cool weather in Washington
during the last month has prevented codling moths from depositing
as many eggs as during the same period in 1931. Up to June 18,

the last few days of May and the first of June this insect began
infesting peach twigs; in Monroe and Wayne Counties it is
steadily increasing. (Abstract, J.A.H.)

L. A. Stearns (June 23): The peak of first-brood twig injury
w-'.s obzcrved during the last week of May and the first wee-: in
June; injury has been moderate; first first-brood moths appeared
June 18.

L. M. Peairs (June 23): The oriental fruit moth is moderately
abundant at Morgantown. There has been more than the usual early
work.

C. R. Willey (June 25): Oriental fruit moths are very abundant
in Richmond, Henrico County and in adjoining counties.

T. H. Parks (June 25): More injured t-rnomnals are found than
usual at this time of year.

E. W. .eindenhall (J-uie 26): In Fairfield County I find the
oriental fruit moth is doing considerable damage to each orchards

S. C. Chandler (June): Twig infestation is more severe than
last year. At present (June 16) second-brood larvae are hatching.

R. H. Pettit (June 22): T.As insect is moderately abundant.

G. M. Bentley (June 22): This insect is moderately abcnOant.

PLLP. CTURCULIO (Conotrachelus nenuphar !bst.)

C. R. Phipps (June 25): Very abundant. Considerable injury
to apples in certain Cumberland County orchards.

IN. Y. State Coll. Apr., Weekly News Letter (June): During the
last week in May the plum curculio emerged in larre numbers and
by the first of June darrmage was quite evident in the Hudson River
Valley. By the third week in the month it was quite :er.,rally
prevalent throughout the State, but on the whole the dam.ae was
not unusual. (Abstract, J.A.M.)

L. A. Stearns (June 23): First-brood grubs commenced issuing:
from fruit during the last weel in May. Drops are heavily infested

C. R. Willey (June 25): The plum curculio is very ab'.-.i.'ant
in Richmond, Henrico County, and in adjoining counties.

0. I. Snapp (May 31): The first pupation of the season was
recorded today at Fort Valley. The first larvae remained in the
soil 15 days before pupating. Pupation is unusually late this
year. It is beginning 6 days later thani last year and 16 da:s
later than in 1930, when the pupation was considered late. T'-he
late pupation this year does not necessarily indicate one :en-
eration, owinz to the fact that the peach crop is correspondingly
late. (June 6): The first pupae to transform to beetles in soil
cells were recorded today at Fort Valley. Transformation is
beginning 5 days later than last year and 14 das later than in
1930. (June 10): The parasites TriasWis curculionis Fitch and
T. curculionis vat. iufus Riley are much more abundant than
usual. This is especially true of rufus. (June 16): The first
new adults of the season emerged fro-i the soil todxw. ie are
expecting second-.-,eration ec-s within two weezs, and Hiley,
Georgia Belle, and iberta peaches will, in all probability,
contain larvae of the second brood.

W. H. Clarh:e (June 10): The first adults of th.e first brood

T. H. Parks (June 25): Very few curcullo marl's are to be
found on apples though some are present on plums and a few on
peaches in some orchards. The infestation is distinctly less
than usual though greater than last year.

S. C. Chandler (June): Apple orchards in southern Illinois
have been injured severely because of the lack' of fruit in the
big peach orchards close by, and the curculios have cozncetrated
on the apples. On account of the scarcity of frait much Carnage
has been done to peaches in southern Illinois. Jarri.-?;s at
present indicate no let-up in the numbers feeding.

R. H. Pettit (June 22): Plum curculios arc very abundat.

J. A. 'lunro (June 18): H. 0. Putnam reports the plum cur-
culio as very abundant on wild plums in the vicinitU of 3ismarck.

L. Haseman (June 20): The plum circuLlio bred earlier th-arn
usual this year. June 10 about 70 per cent of the earl-, collec-
tion of worms were in the pupa stage and June 20 about 30 per
cent were adults. Still feedin:v and breeding.

C. Ijle and assistants (June): The plum curculio i- -,
abundant in the northern and northwestern parts of the State.

500 acres, including some Japanese truck gardens. Later surveys
showed one more ranch infested in the Downey district and
another near Artesia.
H. pisana was first found in San Diego County in 1919 in the
La Jolla district. This was the first and only other infes-
tation of its kind found in the United States. The infestation
was extremely heavy in some places and in one instance 800 snails
were counted on a single wild buckwheat plant less than 2 feet
in diameter and about 18 inches high.

T. J. Headlee, C. H. Nissley, and R. C. Burdette (June 9):
Onion thrips were found throughout the State mainly upon onions
but to some extent upon cabbages, where they stood adjacent to
heavily infested onion fields. The attack on the early onion
in southern New Jersey has already accomplished a large share
of the damage it will do, because through the agency of thrips
and dr- weather the older onions 'ave received a setback from
which they will not recover in any considerable de ree.

J. J. Davis (June 27): Onion thrips began to show up in
thrcateriinz numbers in many sections of northern Indiana early
in June. However, serious damage has not yet developed but is
anticipated in some sections.

L. H. Shropshire (June 23): Onion thrips are multipl'ir-n
rapidly. Commercial dar-.a'-e to onions will occur within a short
time if weather continues hot and dry.

G. M. Bentley (June 22): Onion thrips are moderately abui.dant
on roses in Knox County.

stands of maple this season. Where the leaf eaters ',re most
prevalent the leaves on full-aged trees are 50 to 75 per cent
consumed, the upper leaves of saplings are in like condition, and
leaves on lower branches are all eaten. Thne leaves on seedlings
are eaten right back to the stems. The leaf eater was at work
in milder form in the early summer of 1931 in the Sawyer timber.
The growth of the infested trees will be retarded this year."

BALSAMI TWIG APHID (Mindarus abietinus Koch.)

H. B. Peirson (June).:' Balsam twig aphid observed quite abun-
dant curling needles June 8 at Strong.

PINE TEEDLE SCALE (Chionaspis pinifoliae Fitch)

H. B. Peirson (June): Pine leaf scale observed W'y 30 at
Bar Harbor. Quite abundant on fir foliage. Probably a new
record for this host.

AN APHID (DreYFusia oice.Ratz.)

along the coast of :'I-ine. Large -mounts of fir being killed.


LA RCH

LARCH CASE BEAER (Coleophora laricella tHbn.)

J. V. Schaffner, jr. (June 17): Observations made and reports
received from various sources' during May and June indicate a
general infestation wherever larch occurs in New England.

C. R. Phipps (June 25): 'This pest was very abundant during the
season of 1931 with the result that most of the larch trees in
the State were turned bron.n in June. This condition is being
repeated this season although some of the browning has been
occasioned by late frosts.

H. L. Bailey (June 25): The larch case bearer appears to
have been more abundant than ever before throughout all parts
of the State. A high percentage of the native larch trees were
almost completely defoliated. New foliage was starting on many
of them June 23.

R. D. Glasgow (June 14): The larch case bearer is very rbun-
dant throughout eastern and northern New York:. Adults were ob-
served in 7estchester County on the 8th, and in fWarren County
on the 12th. In northern ITew' York this insect appears to have
become active as soon as the buds opened, the foliage through-
out large areas Lavlr. been destroyed before it had attained any
considerable length. A very large proportion of the tamarack
in northeastern .ew York is now entirely brown. This, insect has
caused serious andprogressively increasing damage to larch in
northern New York during the past 5 years. .'Many tamarack trees
have already died as a result of repeated defoliation by this
insect.

D. C. Mote (roy 18): A serious epidemic of midges is occur-
ring around the lower shore of Upper Kl--xtth Lake. Millions
of the flies strike the wind shields and lodge in the radiators
of autos driving along the Lake. Iumrerous cone-shared .warms
are observed pyramiding up from the bushes and buildin,--:s and
other objects along the road. They alight on the sides of
houses, on weeds, shrubbery, brush, evcry7.hcre. On the porch
of one home near the lake several quarts of dead flies in wind-
rows were observed. The porch had been swept the day before.
Spider webbing on sides of houses and bushes catches the flies,
making an excee Iin17 unsightly mass.

R. Bogue (May 9): A great deal of sickness in Santa Paula

opportunity of observing about 275 head of steck in a corral at

horn flies arc more aoun-&,nt this year than they have been in
several years.

E. 7. Lao!:' (June 10): The average n-ber of horn flies per
