OUTSTANDING ELTC,,0LOGICAL FEATURES 11: T1- UuThID STATES FOR APRIL, 1930
The serious condition in Nebraska with regard to the army cutworm,
reported in the last number of the Survey Bulletin, has continued during
the early part of the month. The ring-necked pheasant was found to be
a heavy feeder on this species, 122 larvae having been found in the
crop of a single specimen. The usual number of spring reports regarding
cutworms is being received from practically all parts of the country.
Wireworms are reported as seriously damaging tobacco in Gadsden
County, Florida, and sweet potatoes in parts of Mississippi.
Many reports were received from Georgia, westward through Missis-
sippi, of June beetle damage to the foliage of pecan. White grubs are
reported as very numerous in the North Central States.
Indications of serious Hessian fly trouble are reported from
Missouri. This insect emerged about a week earlier than usual in Oregon.
The chinch bug remains as during the last few years at a very low
The corn ear worm is now appearing in southern Florida.
Many reports of unusual abundance of the clover leaf weevil have
been received from Illinois and 1Missouri.
Reports of very unusual numbers of crane fly maggots attacking
meadows have been received from Illinois and Missouri,
Fruit aphids appear to be moderately abundant over the 'J..7 England
and Middle Atlantic States but less than normally abundant in the East
Central States. Over the remainder of the country these insects are
reported as scarce.
The codling moth appears, from hibernation counts, to be subnormal
in abundance throughout the country. In many cases this is attributed
to very high winter mortality.
The fall can:-r worm is appearing in outbreak numbers in central
The first moths of the oriental fruit moth appeared during the
first Teck in April in Illinois and the second week in April in Delaware
and southern Ohio. Heavy emergence was observed during the later part
of the second week and the early part of the third week of the month
About the middle of the month the first adults of the plum curculio
were observed leaving hibernation in Delaware and a few days earlier
in northern Virginia. Egg-laying was well under way during the last
week in the month in Georgia. The first weevils were fund in the
trees in southern Illinois on April 14.
The seed corn maggot is again proving very destructive to seed
pieces of potato and to snap beans in the coastal section of South
Carolina. Cool weather conditions delayed germination of the seed,
which is probably responsible for this trouble.
The first adults of the Colorado potato beetle were observed in
the Charleston district of South Carolina on April 5. They were ob-
served at Columbia, Mo., April 21.
A vory serious outbreak of the strawberry weevil is occurring
in the Chadbourn and Burgaw districts of North Carolina.
A number of insects have been noted as attacking strawberry plants
in Washington State. Among these are Tyloderma morbillosa Lec.,
Brachyrhinus ovatus L., Dyslobus decoratus Lec., Geoderces melanothrix
Kby., Coniontis sp., and Eleodes sp.
A report of what appears to be the first collection of the squash
bug in the State of Idaho was received this year. The specimen was
collected in 1929.
The turnip aphid is becoming increasingly destructive in Indiana.
The juniper webworm (Dichomeris marginellus Fab.) is becoming
increasingly destructive to juniper nursery stock in Lnke County, Ohio.
The duodar weevil is causing considerable damage In many parts of
By the middle of the month the bulb flies were emerging in western
The clover mite is attracting considerable attention in the Eastern
and North Central States by entering houses in very large numbers.
The Argentine ant is occasioningconsiderable alarm in many parts
OUTSTANDING -liT0?.-'OIGICAL FEA7FUER. I;I .CANADA FOR APRIL, 1930
The season of, 1929 was. characterized over the greater part of the
Dominion by a cool, backward spring, 'followed by an exceptionally dry
summer, and generally speaking the country as a whole was comparatively
free from serious insect outbreaks.
Weather conditions were favorable to grasshoppers in 1929, and
these insects. increased markedly over a considerable part' of Canada,
particularly in the: dry cattle-range areas of British Columbia and in
sections -of the Prairie Provinces. They were not abundant enough,
ho:;ever, to cause serious crop damage.
*.' I-,'b'deraate boutbreaks of cutworms occurred in sections of New
Brunswick, southern Ontario and the Prairire' Provinces, but damrae by these
insects wasl not considered excessive. The estimated- loss to field crops,
however, in 1929, in Saskatchewan alone, due to cutworm depredations,
was placed at nearly one and one-third million dollars,
Depredations by wireworms were reportedd from parts of Ontario,
the Prairie Provinces, and British Columbia, in 1929, but severe crop
damage was noted only in Saskatchewan and certain dry sections' of Alberta
and in the Okanagan Valley, British Columbia. Th-e loss to grain, and
other field crops in Saskatchewan, due to wireworms, was estimated at
approximately three and one-sixth million dollars.
In Ontario, during 1929, the European corn borer, Pyvrausta
nubilalis Hbn., in general, again showed a decrease in the area in which
compulsory control is being enforced, clear decreases being determined
in sixteen counties. In the counties of Essex and Kent, formerly the
most severelyv'affected, although the stalk infestation was lower, the
number of borers was probably about the same as in the previous year.
The infestation increased. somewhat in eight other counties. In five
counties outside the control area the infestation was low, the number
of borers remainin: about the same as in 1928. An interesting point
noted 7,s the apparent quite rapid increase of the borer on Manitouliri
Island. In ,uebec, although not carefully surveyed, the infestation
on the average is considered tD have remained about the same as in 1928.
In New Brunswick theinfestation is still present. No sign of the borer
was found in the localities infested in 1928, but it was discovered in
very small numbers in other localities in Sunbury, Queens, and Charlotte
Counties. The borer also was discovered in very small numbers for the
first time in .ova Scotia, in the counties of Kings, Annapolis, Digby,
and Yarmouth, and from the stage of development is presumed to be of
the two-generation strain of this species.
The Colorado potato beetle, Leptiaotarsa decemlineata Say, was
about normal in eastern Canada, during 1929, and less abundant and
destructive than usual throughout the West. In British Columbia
it occurs only In the extreme southeastern corner of the Province.
The dry season of 1929 engendered increased crop damage by the
wheat stem sawfly, Cephus cinctus Nort., in sections of the Prairie
Provinces. The loss to wheat in Saskatchewan in 1929, due to the
sawfly, was estimated at five and one-half million dollars. The area
of greatest damage occurred over the south-central part of the Province.
The sawfly also caused noticeable damage in western Manitoba, and in
certain localized areas in Alberta. Given favorable weather conditions
a further increase of the insect in 1930 is anticipated.
An infestation of the pea weevil, Mylabris pisorum L., was dis-
covered for the first time on Vancouver Island, British Columbia, late
in 1929. Efforts are being made to eradicate the insect which so far
has not been a pest in the Province.
Slight infestations of the Mexican.bean beetle, Epilachna corrupt
Muls,., were found in three localities in southern Ontario during 1929.
This species was first discovered in Ontario, in 1927, but the original
infestations disappeared, and it appears extremely likely that climatic
conditions will prevent the insect from becoming a pest in Canada.
During 1929 the plum curculio, Conotrachelusonenuphar Hbet., was
a serious pest in fruit-growing sections of eastern ,Canada. The apple
curculio, Tachypterellus quadrigibbus Say, was particularly abundant
in orchards of southern Quebec, and occurred for the first time as a
fruit pest in British Columbia, causing severe damage to pears in the
Salmon Arm district.
The codling moth, Carpocapsa pomonella L., appeared to be less
than normally abundant in eastern sections of Canada. In'the West,
this species is increasing in the Okanagan Valley and on Vancouver
Island, British Columbia.
The oriental peach moth, Laspeyresia molesta Busck, increased
markedly in southern Ontario and caused serious loss in the Niagara
district, particularly east of St. Catherines.
Budmoths were less abundant in Nova Scotia orchards than for
some years past, but appear to be on the increase in southern sections
of New Brunswick, Quebec, and Ontario.
The apple and thorn skeletonizer, Hemerophila pariana Clerck,
was recorded for the first time in Ontario, during 1929, in neglected
apple orchards of the Niagara peninsula.
The oyster-shell scale, Lepidosaphes ulmi L., appears to be on
the increase in sections of New Brunswick and southern Ontario, and is
becoming a serious pest in the interior of British Columbia.
Spider mites were prevalent in many parts of Canada, during 1929.
The European red mite, Paratetranychus pilosus C. & F., for the first
time was an important pest in orchards of southern NeT Brunswick, and
was abundant and injurious in the i agara district, Ontario. Red spiders
also heavily infested small fruits and various other plants in sections
of Ontario and the Prairie Provinces, and fruit trees in the Okornawn
Valley, British Columbia.
An outbreak of spruce budworm, Cacoecia fumiferana Clem., on
balsam, in the *.estree district, north of the Georgian Bay, Ontario,
which apparently originated around Meteor Lake, is slowly extending
westward. The outbreak of this species on Vancouver Island, British
Columbia, north of Victoria, is subsiding.
The fir sawfly, Neodiprion abietis Harr., was found infesting a
considerable area of balsam forest in the Sault Ste. Marie district,
Ontario, during 1929. An outbreak of this insect in Manitoba has been
much reduced by parasites. An incipient outbreak of a species of sa'-
fly, of the same genus as the above, has been discovered affecting jack-
pine over a considerable area in the Biscotasing district, Ontario.
Severe local outbreaks of the latter insect also were found in Quebec.
The satin moth, Stilpnotia salicis L., which was first recorded
in Canada at ':Te- Westminster, British Columbia, in 1920, now occurs
throughout the Lower Fraser Valley and on the east coast of Vancouver
The European beech bark louse, Cryptococcus fagi Baerns., which
occurs widely in Prince Edward Island and Nova Scotia, is spreading
northward in eastern New Brunswick from the infested area in Albert
and Westmoreland Counties. It was first discovered in Hew Brunswick
The brown-tail moth, Nygmia phaeorrhoea Don., has been practically
eliminated fromCxanada. The only evidence of the pest found since
1927, in the previously infested areas in the Maritime Provinces, was
a male moth captured at Fredericton, New Brunswick, in July, 1929.
Infestations of the gipsy moth, Porthetria dispar L., discovered
in southern Quebec in 1924, in Stanstead and St. Johns Counties, appear
to have been completely stamped out by the vigorous combative measure
adopted. Extensive scouting, continued in 1929, failed to reveal any
evidences of the pest.
J. R. Watson (April 26):
Grasshoppers are moderately
H. C. Severin and A. L. Ford (April 22): Grasshopper eggs
are abundant west of the Missouri River; also in north-
eastern South Dakota. Trouble is expected in alfalfa-
growing districts especially.
G. F. Knowlton (March 29): A few half-grown grasshoppers
were observed at Snowville today. These are the first I
have encountered this spring. (April 23): Grasshopper
nymphs which were in the first and second instar were
collected west of Corinne, and at Snowville. Very few
young grasshoppers have been observed up to the present
time. (April 24): A few first and second instar nymphs
of grasshoppers were observed in sugar-beet fields at
G. F. Knowlton (April 12): An adult of the grasshopper
Hip-piscus corallipes Hald. was collected at Skull Valley
April 12, and nearly mature nymphs were collected at
Grantsville, April 3, and at Cedar Spring on March 29.
This form overwinters in the nymphal condition and is
frequently present in damaging numbers in Tooele County.
C. P. Gillette (April 22): The grasshopper Anabrus simplex
Hald. is scarce in Routt County.
C. H. Brannon (April 25): Cutworms are causing severe
damage to tobacco and truck crops all over eastern North
Carolina. In New Hanover County cutworms have caused con-
siderable damage to lettuce by eating into the head.
J. R. Watson (April 26): Cutworms are moderately abundant.
J. J. Davis (April 28): Reports of cutworms are absent
except for one outbreak reported in a greenhouse. The
variegated cutworm (Lycqphotia margaritosa Ha'., var.
saucia Hbn.) reported damaging foliage of tomato and flowers
of calla and carnation in a greenhouse at Decatur March 31.
H. C. Severin and A. L. Ford (April 22): Cutworms are
abundant in eastern South Dakota.
L. Haseman and P. H. Johnsor. (April 21): Two or three
species of cutworms seem to be unusually abundant. As yet
no damage has been reported.
K. C. Sullivan (April 23): Cutworms are reported at
Anderson in cornfields following alfalfa.
M. H. Swenk (April 17): Cutworms (Euxoa n xillris Grote)
are moderately abundant on wheat in southeastern Nebraska.

during early April. A ring-necked pheasant that flew
against the windshield of an auto near Morrill, Scotts
Bluff County, on April 8, contained 122 army cutworms
in its crop.
R. L. Parker (April 21): The pale "-estern cutworm
(Porosagrotis orthogonia Morr.) is reported as very
abundant on wheat in western Kansas. (April 24): The
clay-backed cutworm (Feltia gladiaria Morr.) is abundant
in the vicinities of Grinnell, Oakley, and Greenfield.

generally reported as being scarce throughout the State,
but Agrotis ypsilon Rott. is moderately abundant at
C. P. Gillette (April 22): A cutworm is reported as
moderately abundant in Routt and Sedgwick Counties.
C. ',7akeland (April 22): The usual reports have been
received of serious injury by cutworms to gardens in several
parts of the State.
D. C. :'ote (April 21): Cutworms are very abundant on
garden plants, young strawberry plants, and flowers. L. P.
Rockwood reports that it is still too early to find readily
Euxoa messoria Harr. and Euxoa septentrionalis Walk., garden
cutworms of the true cutting type, which wintered as eggs
and may have survived the winter better.
L. P. Rockwood (April 15); Cutworms, Agrotis c-nigrum L.
and Neuria procincta Grote, are not so numerous as usual at
Forest Grove, perhaps because of unusually severe cold in
January; Cirphis roseola Sm. is about the same as usual.
',7m. `,. Baker (April 3): Cutworms are destroying a large
number of new plants in both old and ne- sod at Grand :'ound
and Rochester, few occurring in old plantings but fields
plowed last fall and replanted this spring are as seriously
affected as fields planted on ne. land.
A NYMPHALID BUTTEIRFLY (Euohydryas ylori Ldw.)
Wm. W. Baker (March 21-April 10)' .hat appears to be
this species was observed to be very numerous in the prairie
district around Grand Mound, the caterpillars literally
covering the ground in places. Very little evidence of
feeding was found on March 21 but on April 2 some fading
was noticed on buckthorn plantain. Pupae also were f:uni on
the latter date. The first butterflies were noticed on
Harold L. Bailey (April 18): Wireworms are moderately
F. S. Chamberlain (April 23): Wireworms have necessitated
the resetting of tobacco in some fields in Gadsden County.

K. L. Cockerham (April 7): Eight and six-tenths per cent
of the adults of Heteroderes laurentii Guer. which -ere
placed in hibernating cages last fall 7ere alive on April 7
when the cages were examined and taken up. These beetles
were placed on the surface of the ground in trash, potato
vines, etc., and enclosed in screen-wire cages. During the
winter the lowest temperature recorded here was 18 F.
R. 77. Harned and assistants (April): Wireworms are
moderately abundant in many parts of the State, being often
recorded as injuring sweet potatoes.
C. h'akeland (April 22): Wire-orms are reported in szuth-
western Idaho. Adults emerged in early March and Mr.

them as very abundant.
.,'hIir GRU3S (Phyllophaga spp.)
J. B. Gill (April 25): May beetles have been devouring
the shoots and foliage of pecan trees at Albany and Aiericus.
:To extensive damage has been ob.--rved in pecan orchards.
J. S. Houser (April 16): Thite grubs are very abundant.

in Houston County.
L. Haseman and P. H. Johnson (April 21): Wnite grubs
are reported scarce. Adults are just beginning to fly.
Some damage has been noted at Columbia.
J. "". Robinson (April 25): On April 12 we had a letter
from S. M. Day, County Agent, Alexander City, stating that
the adult bro'n June beetles (Phyllophaga rugosa Melsh.
and Phyllophaga tristis Fab.) were destroying young pecan
foliage, rugosa being more abundant than tristis. Phyllophaga
rugosa was Llso reported as active on pecan foliage at
R. J. Earned (April 22): J. M. Langston reports that :lay
beetles began flying to lights at A. & M. College on March 14,
and have continued in increasing numbers. They have attracted
attention over the State. Serious injury to pecans was re-
ported on April 17 from Sallis, where 24 males and 6 females
of Phyllo-phaga praetermissa Horn were collected from one small
Stuart pecan tree. A correspondent at Carriere wrote as
follows on April 15: "They are camping nightly in front of
my home and destroying all evidence of new growth on the
trees." Specimens that accompanied this complaint were
identified by J. M. Langston as Phyllophaga arkansana Schaef.
R. .7. Earned and assistants (April): These insects :'.-ere
first observed in large numbers on March 27 when they were
flying around lights in George, Green, and Perry Counties.
Since that date they have been quite prevalent throughout
the State, being particularly abundant on pecan trees. The
following species were observed: Phyllophaga hirticula Knoch,
foster .Burm., luctuosa Horn, micans Knoch, and ulkei Sm.
JAPANESE "ITLL (Popillia japonica l!ewm.)

abundant west of Garland, and a few of the same species were
collected at Snowville and Curlew Valley, all in Box &dr
CEREAL AND FORAGE-CROP INSECTS
HESSIAN FLY (Phytophaga destructor Say)
J. S. Houser (April 16): The Hessian fly is scarce in
J. J. Davis (April 28): The Hessian fly is moderately
abundant in southeastern Indiana.
L. Haseman and P. H. Johncon (April 21): The Hes-ian
fly is reported from Columbia and the State of Lissouri
as a whole as being very abundant. Such reports indicate
a serious outbreak. In central Missouri flies actively
oviposited April 10-22. Damage from the spring brood of
maggots is not yet in evidence.
:.. H. Swenk (April 15): The Hessian fly has been emerging
since April 1 and at the present writing the bulk of the
flies of the first spring brood seem to have emerged. A
Gage County correspondent reported on April 7 that the
fly puparia in his field were mostly empty on that date,
whereas on /arch 17 emergence had not started. (April 17):
The Hessian fly is moderately abundant in the southeastern
part of the State.
R. L. Parker (April 24): The Hessian fly produced eggs
Max .. Reeher (April 15): The first spring brood emerged
March 31 at Forest Grove. This is about a week earlier than
the average for the first spring emergence.

determination. (Det. by H. E. Ewing)
COR 1 *
CORY FLEA BLJLE (Chaetocnema pulicaria Melsh.)
C. H. Brannon (April 20): Speci.ens were sent in from
the county agent of Robeson County with the report of con-
siderable damage to corn.
POTATO FLEZ.- BEETLE (Epitrix cucumeris Harr.)
W. A. Thomas (April 12): A very serious local outbreak
of the potato flea beetle in the Chadbourn district has
occurred within the past week. Areas of young corn, just
well up, have been seriously injured. As many as a dozen
specimens were observed feeding on a single leaf, leaving
only skeletons of corn plants in their wake.
CORN EAR WORM (Heliothis obsoleta Fab.)
J. R. Watson (April 26): The corn ear worm is reported
moderately abundant over the southern part of the State.
ALFALFA 7-D CLOVER
ALFALFA WEEVIL (Phytonomus posticus Gyll.)
G. G. Schweis (April 18): The alfalfa weevil is reported
as very abundant at Reno. Oviposition to date is greater

were full-fed and had begun to spin cocoons April 15.
ALFALFA CYTERPILLAR (Eurvus eurvtheme 3oisd.)
Utah G. F. Knowlton (April 28): A few alfalfa butterflies
are present in the fields in northern Utah.
CLOVLR ROOT EGRER (iylastinus obscurus Marsham)
Oregon L. P. Rockwood (April 15): Adults were flying on March 2;
when the maximum temperature reached 82 F. This is the
earliest date ever recorded for the flight of this species
at Forest Grove.
"STIR.I SPOTTED CUCLi'..BER BEETLE (Diabrotica soror Lec.)
Oregon D. C. Mote (March 28): B. G. Thompson reports "tabrotlca
soror Lec. present in young clover fields in considerable
T. R. Chamberlin (April 15): Adults are not so numerous
as usual in 7,'ashington County and have not damaged the stands
of seedling clover appreciably.
PEA APHID (Illinoia pisi Kalt.)
Kansas R. L. Parker (April 24): The pea aphid is appearing in
large enough numbers to cause an outbreak under favorable
Utah G. F. Enowlton (April 28): The pea aphid is still very
scarce on alfalfa and peas in Davis County.
N7evada G. G.;.Sch-eis (April 18): Alfalfa aphids are reported
as very abundant at Reno and Minden. Severe injury in small
acreages has occurred in these two outbreaks.
Oregon L. P. Rockwood (April 15): Very little vetch -as seeded
early enough in the fall of 1929 to become infested in the fall.
In one young orchard where vetch was seeded in August 1929,
much vetch 'vas killed by a heavy aphid infestation in October
and November. In March and early April, 1930, Illinoia pisi
7'as making a slow start on this vetch, apparently owing to the
fact that very few aphids survived the winter. There were
from 25 to 100 aphids per swe.p here April 11. Coccinellid
adults of several species averaged from 10 to 100 per sweep.
Spiders were very numerous. Alfalfa fields are lightly in-
fested, 30 to 100 per sweep on April 5. Coccinnelids and
spiders were numerous on alfalfa also. Stem mothers of the
aphid were scarce on Scotch broom in Clackamas County in late
March. Sexual forms were scarce on this host last fall in
most places and the host plants were in many cases badly in-
jured by cold during the winter.
CLOVER SEED CHALCID (Bruchophagus funebris Howard)
C. P. Gillette (April 22): The clover seed chalcid is
moderately abundant in alfalfa districts of the State.
CRAIE FLIES (Tipulidae)
S. C. Chandler (April 15): A number of records of tipulid
larvae have been submitted with the statement that they were
causing injury. It has been impossible to verify this state-
ment in any case.
L. Haseman (April 9): Je are just now experiencing what
appears to be a very extensive outbreak of one of the medium-
sized crane flies, specimens of the larvae of which I am
sending to Dr. Alexander for identification. The outbreak
seems to extend particularly along the northern side of the
M:issouri River and is heaviest in and surrounding the village
of Centralia, just north of Columbia. -7e are getting a great
many letters and sample every day. Undoubtedly this is an
entirely different species from the western forms, but they
are appearing in pastures and meadows and other crops in
enormous numbers and some farmers are complaining that
timothy meadows are being injured severely. This is the
first heavy outbreak we have ever had and from my own ob-
servations to date I am not sure just how much damage this
species is doing, if in fact it is actually injuring crops at
all. It certainly is abundant enough to do serious damage
if it has the habit of attacking roots and cro-'-ns of grasses
and other croos.
L. Haseman and P. H. Johnson (April 23): An undotrmrinL-d species
of crane fly is very abundant in central :..issouri. Some report
as many as 100 to a square foot of ground. Some fart.rzs
claim that they have injured grass but in bre-i-in- cages.
they do not seem to eat the roots of grass. They are still in
the larval stage.
Z R R I T I C,
,. E. Britton (April 24): Fruit aphids are moderately
Weekly News Letter, N. Y. State Coll. Agr. (f-ril):
During the first week in April aphids were observed in both
the Hudson "iver Valley and Lake fruit belts, and by the
middle of the month they were quite generally observed
although they do not appear to be so numerous as last year,
being mostly the apple grain aphid and the ar.-le aphid.
There were very few rosy aphids observed, although in
Ulster County they were very conspicuous by end of month.
-i. J. Schoene (April 21): All three species of aphids,
now found in apple orchards, are present in vary small
numbers this year. It is assumed that this scarcity of
aphids is due to an early freeze which destroyed the foli7o-
before the overwintering eggs were deposited.
J. J. Davis (Dlarch 31): Apmle aphids (apparently both
Rhopalosiphum prunifoliae and s pomi) werc hatching
archh 10 at Mitchell according to Steiner's observations.
Apparently some had hatched the 8th and 9th. Suds were not
showing green at the time and for about a week (at least until
the 15th) many of the young starved to death.
S. C.Chandler (April 15): There is a scarcity of fruit aphids
but all three species were found on apple in southern illinois.
R. H. Pettit (April): Apple aphids are hatching every-h-ere.
L. Haseman and P. H. Johnson (April 22): The fruit aphids
are reported as moderately abundant at Col-mbia. '-lot in-
creasing seriously from April 15 to April 22.
G. F.IKnowlton (April 19): The fruit aphids are scarce
on apple and plum in Boxlller and Cache Counties.
P. R. Lowry ( pril 15): The c-re,.n a- le aphid ergs seem
about normal in abundance in the southern part of the State.
'0 hatching: yet.
Harold L. Bailey (Arril 18): .oderstely abund.'nt in
'APPLZ A.ID (Apl-.id pomi DeG.)
A. I. Bourne (April 21): At the present time apple plant
lice have only recently begun to appear on the buds. These
began hatching from April 8 to 12, depending on the section
of the State. As'a rule they are found generally present
but not very abundant in any orchard. This is in marked
contrast to last year's experience when they hatched in
large numbers. and threatened to be a serious problem to the
growers during the early season.
SNeely Turner (April 21): The initial infestation is not
sufficiently large to cause an outbreak unless weather
conditions are very favorable. Syrphid-fly eggs are de-
posited on buds in-about the average number.
C. H. Alden (April 21): There are few green aphids at

year from the same orcr.e-rd treated according to the same spray
schedule. Of those collected from trees dusted according to
the recommended dust schedule, 23.5 per cent were infested
"'ith curculio larvae as compared with 55 per cent infestation

figures a comparison can be ;made of the early-season curculio
infestation in 1929 and 1930.

",cre fjunu in small peaches todr.y. The appearance of adults
from hibernation is much less than it was t. this time last
year, and may indicate a lighter infestation throughout
the season, although the spring has been unusually cold
and rainy and this may be keeping then in hibernation later
than usual. (April 21): The oldest curculio larvae
are now7 7 to 10 days old. :e are expecting larvae to begin
leaving peach drops around Ajril 28, which is later than
usual and may result in only one generation before the
close of the peach season. '.Thile the appearance of adults
from bibaruetion has been heavy during the last two weeks,
the infestation is lighter than last year ani may be con-
sidered a normal one.

P. J. Char,,nn. (April 22): The secd corn maggot is moderately
abundant at liorfolk.
W. J. Reid (April 15): Injury to freshly planted seed
potatoes has apparently been as generall in the Charleston
district as during the past two seasons, but the number of the
insects has been slightly less. Freshly planted potato seed
pieces were attacked by the mag-ots during the entire month
of Mviarch and to the middle of April, by which tiT", all larvae
had pupated. The infestation was as high as 50 per cent in
many fields. The insect has been found to be closely
associated with seed-piece decays.
W7. J. Reid (April 4): The seed corn maggot has been
unusually destructive to snap beans in the Charleston district
during the past three weeks. Th,7ther conditions have delayed
germination of the seed and growth of the seedlings, and these
conditions have apparently favored the insect. The maraots
attacked the cotyledons, plumules, and stalks of the seedlings.
Beans planted in land containing considerable decaying organic
matter have suffered most from the insect. In a field planted
in beans immediately following a spinach crop at least 75 per
cent of the seed or seedlings were attacked. In this particular
field a count of a representative number of hills in different
parts of the plot showed that 34 per cent of the hills were
either entirely missing or the plants so seriously injured that
they were dying. It is entirely possible that many other
plants will die because of injury to their roots.
L. Haseman and P. H. Johnson (April 22): Only one report
