The usual reports of more or less serious cutworm damage were re-
ceived fr'-,m -rractically all parts of the United States. Unt snl damage
by these insects w,.s reported from North Carolina, North Iakota, Nebras-
ka, Montana, and parts of Idaho.

Serious Hessian fly infestations are re-ported from western Illinois,
part of the Platte Valley in Nebraska, and limited areas in Iowa. In
Henderson County, Illinois, considerable wheat is being plowed out on ac-
count of infestation.

During the middle of April the chinch bug started migrating into the
fields in Illinois. 3>,. the middle of the month migration was observed in
,Missouri and Kansas. There is a decided indication of serious chinch bug
trouble in southeastern Kansas.

The clover leaf weevil is rep-orted as very abundant in central Illi-
nois and arts of Iowa, Missouri, Kent-ucy-i and Kansas.

The pea aphid is re-orted in outbreak numbers in parts of Kansas and
northeastern Arkansas, Arizona, and southern California. Isolated infesta-
tions were reported from Mississi77i. The infestation re-norted in the
last number of the Survey Bulleting from the Uillamette Valley of Oregon
increased materially during late tMarch.

Dr'Cmage by the shot-hole borer is reported to be unusually severe in
Ohio this spring,. In view of the very extensive and serious drought of
1930 it is surinrising th-it severe by this insect is not more ex-
tensively observed.

The first record for 1931 of the pu--ation of codling moths was made in
Missouri on A-ril 3; at Cornelia, Georgia, Arril 15; at Carbo:-idale, Ill.,
April 12; at Urbana, Ill., April 14; in Nebras:a, April 13; in Pennsylvania,
April 21; and in ':.ryl-inO, Arril 21. The insect is quite generally report-
ed as normally abundant throughout the Middle Atlantic, South Atlantic, and
East Central States. In the Rock;y Mountain r.. :ion the insect is reported
as very abundant .in Nowr 'TMxico, and as having sustained a very.' slight mor-
tality in Idaho.



The Eastern tent caterpillar appears to be below normal in numbers
throughout the New England, Middle Atlantic, and South Atlantic States.

Decido.ous fruit aphids are reported as quite generally below normal
in numbers along the Atlantic Seaboard from Massachusetts to Georgia,
and westward to Missouri. Reports of an unusual abundance of deciduous
fruit aphids have been received from Mississippi. A limited heavy
infestation of the apple grain aphid is reported from ievw York State,
and owing to the unusually mild winter the woolly apple aphid was as
numerous during the first week of April in Wenatchee, Wash., as they
were in July of last year.

Apple leafhoppers are reported as unusually abundant in Connecticut
and the East Central States. ThLey are so numerous in parts' of Missouri
that the fruit growers are becoming alarmed.

The first emergence of the oriental fruit moth to be reported from
Georgia was on April 8, at Thomaston. Adults were observed at Roanoke,
Va., on April 14.

A very heavy migration of the common red spider into fruit trees in
western 7ashington indicates that the very serious outbreak of last
year may be repeated this season.

The plum curculio appears to be delayed in emergence in the South
Atlantic States. Only 3 beetles were collected at Thomaston prior to
April 4, on which date 35 adults were collected in two hours by jarring,
This is about three weeks later than general emergence last year and the
latest emergence in i1 yp erId- ts were observed for the first time
on April 14 in Virginia annIllinois, and on April 15 in Kentucky.

Heavy infestations by the rusty plum aphid are reported from Georgia
and Mississippi.

The grape leafhopper is more abundant than usual -in the commercial
grape sections of northern Ohio. Damage from this: insect is more abun-
dant than ever before recorded in the San Joaquin Valley, California,
and in the central part of the Valley the insects are so numerous that
the small leaves are turning brown.

A severe outbreak of the six-spotted mite has occurred over the.
entire citrus belt of Florida and some defoliation has resulted where
spraying has been neglected.

''The vegetable weevil continues to be a serious pest on a variety of
truck crops in Mississippi. ,

The first adult of the spotted cucumber beetle to be o]oserved in
Virginia this season was seen at'Norfolk on April 3, and th=- first adult
was reported from Illinois on April 15.


The western s-notted cucumber beetle is making serious inroads on fields
of seedling clover in the Jlill- nette Valley of Oregon, and is doing consider-
able dama-o to melons in the San Joaquin Valley of California.

The Colorado notpto beetle is re':orted as unusually abundant in the
Chadbourn district of -Torth Carolina, and in the Norfolk district of Virgi-
nia. There is also quite a henvy infestation by this insect as far south
as Alachi1a County of Tlorida.

The' seed corn maigot is not so serious as usual on -'otato seed nieces
in the tr.cki.1' sections of Vir:;inia and the Carolinas, although it is re-
norted as causing considerable damage to sna- beans in .Torth Carolina, and
doing considerable damage to corn, ipeas, and beans in western Texas.

The cabbage webworm became so numerous on tuirnip greens about Lucedale,
Miss., that canni-g operations had tobe sus-ended.

Large quantities of spinach harvested early in April had to be rejected
on account of the unusually heavy infestation by the green -neach aphid in
the Norfolk district of Virginia.

The first adult of the harlequin bug to bo observed in Virginia this
season was collected Arril 9. The first s'-ecimen observed in the Chadbourn
district of NIrth Carolina was recorded as of A1ril 21.

The most serious outbreak of buffalo gnats in m'n, years was re-orted in
Covhoma and Tunica Counties, Miss., in the early part of Anril. It was es-
timated. that more than 200 mtles, besides other livestock, were killed by
gnats within a day or two. Similar re-ports of serious infestation were re-
ceived from parts of Arkansas. Buffalo *n'.ts, Simulium vittatum Zett., were
seriously infesting mules, cattle, and hogs south of 7est-nmoreland, Kans.

OUTSTA2. 1:5 z:70jOLOGICAL FTUR- S 11 CAIN TA.'D. 'OR A!T-IL, 1931.

Grasshopr-ers have been on the .-,v'ard trend in many carts of Canada,
particularly western Canada, during the past two years, and althougJa they
were not sufficiently abundant last :,c.,r to cause serious cro- 10- ,'C, it
is antici-pated that serious outbreaks -ayvr develop in many parts of the
rrairie rrovinces and "British Colu-mbia, if conditions continue favorable
during 1931 and 1932.

The pale western cutworm craus- serious cr'op losses in Saskatchewan
and eastern Alberta, during 1930. In Saskatchew-n, the insect .greatly
extended its range and the outbre2:l v-nz the worst so far experienced, the
most se'.'ere losses occurring in the south-central region of the province.
It is forecast that if weather conditions are average, cror losses will
be even greater in the infested regions during 1931.

The red-bac'-ed,. cutworm ,also was a pest of i-mortance over a large
-art of the 'rairie provinces during 1930, attacking grI-in crops, clover, and


vegetable and other garden plants with. resultant: severe logs-es-in =any

Cutworms, in general, were not notably trouble-some crop pests in
eastern Canada, 'during 1930, and they were scarcer and less injurious
than for many yeirs ih British Columbia. The bertha armyworm, which
caused crop dmnage in the Prairie Provinces, in 1929, also was scarce.

Few reports of damage by wireworms were received from &astern Canada
during 1930, although quite severe injury was noted in sections of
southern Quebec and southwestern Ontario. In the West, wireworm depreda-
tions were slight in Manitoba, average or below average in Alberta, and
much less than in 1929. in S-skatchewan. Damage by these insects was
worse than usual in British Columbia, particularly in the Okanagan,
Fraser, and Bulkley valleys.

Mvhite grubs were markedly injurious in sections of Quebec and eastern
Ontarioj during 1930, and a major flight of beetles is forecast for May
and June, of the present year, over a large area of southern Quebec.
D-.--re to field and garden crops by second and third-yea-r grubs will
continue in many sections.

The European corn, borer again showed a decrease in infestation, in
1930, over the greater part of the area in Ontario where corn is a major
crop. In areas throughout the province were field corn is of little
importance, however, a definite upward trend in the infestation of sweet
corn was noted. In Quebec, infestations continued relatively light, and
in the Maritime Provinces, they are still comparratively negligible.

The Colorado potato beetle was not more than normally injurious in
most parts of the Dominion, during 1930, although a moderate increase in
abundance over 1929 was reported from parts of the Maritimes and the
Prairie Provinces.

Reports indicate an increased abundance of the wheat stem s.'.wfly in
the Prairie Provinces during 1930, but crop damage was generally less
severe than-in 1929.

The diamond-back moth occurred in outbreak form inr the Dominion west
of 'Manitoba, during 1930, considerable acreages of cruciferous crops
being severely damaged or destroyed in the provinces of Saskatchewan,
Alberta, and British Columbia.

Flea beetles of several species were again troubl-r -o-me pests in
various parts of the Dominion during 1930.

The only reports received during 1930. concerning the Hessian fly
were from '.a.nitoba and Saskatchewan, where the insect was reported as
scarce, and from' Vancouver Island, where it caused local damae to wheat.

In late summer, 1930, the green bug, Toxoptera !,ramin'm Rond., was
recorded for the first time in outbreak numbers, effecting material


damage to oats in sections of- western Manitoba and eastern Saskatc. an.

Bulmoths continue to decline in-Nova Scotia" and in the St. John
valley, sewv Brunswick. In Ontario the ",'ud.oth situation appears to be
gdt-a?'ualy ir"cproving, although considerable a'n-E was caused in cimO
localities, during 1930.

The codling: moth was unusually injurious in the Maritime Provinces
and Ontario during 1930, but'was notably scarce and less injurious thaLn
for many years in British Columbia.

The oriental fruit ..-.oth decreased to a marked extent in peach orchards
of the Nia.-ara peninsula, Ontario, during 1930, due to natural control

Spider rites were abundat and destructive on a variety of plants, in
n.-ny parts of Canada, particularly in the Prairie Provinces, during 1930.

Larvae of a tussock moth, believed to be the white-marked tussock,
were found attacking fir, zhite spruce and rider, in sections of Nova
Scotia, in 1930. In British Columbia. the tussock mioth, He'ner'cma .-a
pseudotsugata McD., defoliated l-*r.e aren.s of Dou.::las fir in sections of
the province.

During 1930. the satin moth was found for the first time in eastern
Cana-", in the M".ritime Provinces, at several points in IT,-. Brunswick and
iT)va Scotia. Previously it was known to occur only -in British Columbia,
where it wa.s discovered in 1920.

The outbre-k of the her-dlock looper which developed on the north shore
of the St. Lawrence River, in.Que*bec, between the Bersimis and Pentecote
Rivers, and was severe in 1928, decli-ied in 1929, and subsided entirely
during 1930. T:-e extensive rainfall in the infested region during the
past t-;o years is believed to have been an important factor in the decline
of .the insect.

Bark beetles are on the increase over large areas in British Colunbia,
cnd, during 1930, were unusually destructive, particularly affecting
western yellow pine and lodgepole pine.

The tip moth continued to cause' material injury to balsan
and white spruce .on Cape Breton Island, Nova Scotia, aLnd to balszar, hemlock,
Douglas fir,;h-and Sitka spruce over a lar-e part of the coast section of the
southern mainland of British Colu-.':ia.

Further scouting for the brown-tail moth in Nova Scotia revealed no
signs of this pest, and supports the belief that it has been exterminated
in Canada. Scouting for the gypsy moth in the easternn tovwnships of Q-ebec,
where a local outbreak was discovered in 1924, indicates that this species
also has been completely sta:.:ped out.

P. K. Harrison (April 17): The first specimens of larvae of
Horistonotus uhleri Horn,were collected in first 6 inches of
soil, three in fai iOw soil, and one in soil that is being
cultivated, at Fairfax.,

J. N. Tenhet (April 15): First indications of activity of
H. uhleri Horn. at Fairfax this season were noted this week.
.-,e spring has been late and cold and wireworm activity is
occurring later than usual.

K. L. .Cockerham (April 10): On April 10, examinations at
Foley showed the following: Around cabbage plants set 18
inches apart there were 1.4 wireworms (Heteroderes laurentii

(Paul H. Johnson)

W. E.,Hinds (April 23):- May beetles (Phyllophaga sp.)
were reported in enormous numbers at lights at Franklin on
1. rch 20, emerging during a sultry pc-iod just preceding a
thunder storm on that night. They were also reported as
stripping foliage from young pecan trees at Jennings, about
the middle of April. P. congrua Lec. was taken in large
numbers at trap lights at Franklin, April 16 and 17.

R. P. Colmer (April 19): May beetles observed cutting
young foliage on seedling pecans.

GREEN JUNEJ BEETLE (Cotinis nitida L.)

W. A. Thomas (April 10): The work of this insect is much
in evidence on the lawns in Chadbourn. Unsightly mounds of
earth may be seen on nearly every lawn and in a few places
the crass shows signs of dying.



W. E. Hinds (April 23): A. undulata Melsh.and A. innuba
Fab. have been taken in srr1l numbers at trap lights at
Fr-.r:lin, April 16 and 17.

RED SPIDER (Tetranychus telarius L.)




L. Haseman (April 24): During the month a nur..ber of
complaints were received regarding red spiders on ornanentals.

H. Gladney (April 17): The red spider is very abundant on
citrus and vetch at Ocean Springs, Jackson County.

M. A. Others (April 6): A, tremendous migration from the
ground and the bark of tree trunks of Delicious and Winesap
apples up into the trees was first noticed at Wenatchee
April 6. Thousands of trees have been treated with sticky
tree-banding material to prevent migration. Some red spiders





are already up in the trees, which are the cluster-
bud stage. First 'eggs for the season are being deposited.
Orchardists !-re spraying with summer strength lime-sulphur
to destroy the mites above the bands. Last season infesta-
tion was first noticed in July. There was serious loss
after that time, the trees becoming defoliated and the fruit
ceasing to grow further.



HESSIAN FLY (Phytophaa destructor Say)

W. P. Flint (April 20): J. H. Bigger reported severe
infestations in western counties. In t-vo hours'time he saw
100 acres in threD fields in Henderson County which were to
be plowed up because of this infestation. (April 8)

C. J. Drake (April 27): The spring brood is emerging
throughout the State. In the heavily infested counties the
flies occur in great numbers.

M. H. Swenk (March 1-April 15): The Hessian fly is in
general moderately abundant over the southeastern part of the
State in early-sown and'volunteer wheat, but is menacing only
in those sections where the July rainfall was about normal
or where the caTpaign last fall for the destruction of the
volunteer and delayed sowing of the crop received less than
normal support. Field investigations show that in the Platte
Valley counties from northern Saunders and Colfax Counties
to Hall County there is a rather heavy infestation in many
fields. In Colfax County the infestation in two fields was
3.6 and 4.25 puparia per infested stem. A Platte County
.. fieal.d showed 56 per cent of the stems infested with an average
of 1.77 puparia per infested stem. In Hall County the fly is
quite plentiful, with volunteer wheat very heavily infested.
Early sown fields in York and Jefferson Counties have been
considerably injured in a number of cases. A survey of
Lancaster, S-oward, northern Saline, western Cass, and southern
Saunders .Counties that has just been completed showed rela-
tively light infestations except occasionally in early sown
or volunteer wheat. The worst infested field in this area
was an early sown one northwest of Lincoln which showed
17 per cent of the stems to be infested with an average of
1.4 puparia per infested stem. Fields which were sowv on
or after the announced fly-safe date are practically free
from infestation. On April 15 but few of t'he flies had
-emerged from the puparia, but there were many pupae present
and a heavy wave of emergence is apparently due. (April 20):
The Hessian fly is moderately abundant in Platte Valley from
Fremont to Grand Island and locally southward.







H. E. Jaques (April 24): The Hessian ly is scarce in
Osceola, Cass, and ;.,ison Counties; moderately abundant in
Harrison, Mills, Crawford, Warren, Monroe, Henry, Des 1Moines,
and Page Counties; and very abundant in Monona, Fremont, and
Polk Counties.

M. M. Reeher (MIarch 19): The Hessian fly began emerging at
Forest Grove on the 19th of lkrch. On account of the dry
season last fall most of the spring emergence will come from
overwintering flaxseeds on the stubble, as few flies emerged
and little volunteer-wheat appeared until too late for


CHINCH ,TjG (Blissus leucoIterus Say)

7. P. Flint (April 20): Chinch bu,-s are now flying and
have flown to fields in the' central and south-central parts
of the State. A considerable area shows bugs abundant enough
in the small grain fields to cause very serious losses if the
weather remains dry or even normal. (April 20): J. H. Bigger
reports that chinch bugs were suen flying in n-..d and
S.'Lrn7g:'on Counties April 14, in Hancock County April 17, and
in Ad as County April 15. Heavy infestation in portions of
Menard and Sangamon Counties. The Christian County Farm
Adviser reports extremely large numbers.

L. Haseman (April 24): T.-he.c chinch bug is very threatening.
Over-wintering bugs migrated April 15-16.

H. Rb Bryson (April 23): Infor:.ation taken from the Kansas
Weekly Crop Report dated March 20 indicates that cinch bur-s
may become a menace in the southeastern counties and than
many survived the mild winter in spite of bur-iin.; campaigns
carried on in this area to reduce the number emerging from
hibernation this spring. Additional information in tli. -,'ekly
Crop report of April 20 records an observation of the county
agent of Wilson County who observed a flight of bugs on April
11. Large numbers of bugs apparently survived the .mild winter
in that county. Chinch bugs are reported as h'nving. killed 25
acres of newly sown wheat last fall in Sumner County and are
abundant in that locality this spring. Chinch bugs are scarce
but present at ManLhattan.

C. F. Stiles (April 27): Chinch bugs are very numerous in
the northeastern part of the state, in some counties in
the north central portion. One farmer reports that wheat is
firing (?) in Nowata County. The_,e pests overwintered here
at Stillwater in lar,. numbers. Wle expect serious darr:.e






.nless the weather is unfavorable to chinch bug development
before the small grains are cut.

CORN EAR WOVRM (Heliothis obioleta Fab.)

J. R. Watson (April 21): The corn ear worm is scarce,
except in the southern part of the State where it is moder-
ately abundant.

L. Haseman (April 24): Diggings at Columbia revealed 1
pupa of the corn ear worm, 3 dead, and 4 decomposed.

R. W. Harned and assistants (April): H. H. Carpenter
(April 20): The corn ear worm is scarce in northern

W. E. Hinds (April 23): The corn ear worm has not been
found yet at Baton Rouge.

CORN FLEA BE2TL (Chaetocnema pulicaria Melsh.)


R. W. Harned (April 22): Complaints of killed or more or
less severely injured corn, accomrrpanied by specimens of the
corn flea beetle, C. pulicariahave been received from Lee,
Lauderdale, Neshoba, and Leake Counties.

CORN SEED BEETLE (Agonoderus pallipes Fab.)





W. P. Flint (April 20): Corn seed beetles flew out of
hibernation in Warren County April 7.


ALFALFA WEEVIL (Phytonomus posticus Gyll.)

G. G. Schweis (April 21): The first eggs of the alfalfa
weevil were observed on April 6 at Reno.

P SLEAF WEEVIL (Hypera punctata Fab.)

W. P. Flint (April 20): The clover leaf weevil is very
abundant in central Illinois but frequent light showers and
warm weather are producing conditions so favorable to the
growth of the clover plant that there will be no permanent
damage from the weevil.

W. A. Price (April 22): The clover leaf weevil larvae are
very numerous and doing much damage to clover at Brandenburg,
April 8.

H. E. Jaques (April 24): The clover leaf weevil is doing
serious damage in some clover fields in Des Moines County.

J"' 4 A





KA nsas
Kan sa s




C. J. Drake (Ao ril 27): The clover leaf weevil has been
reported by the county .gae:ts in the counties of Madison,
Union, and 7.Tashin-ton 's occurring in large nru'bcers in
clover fields and doingF a considerable amount of damage.

L. Haseman (April 24): The clover leaf ;vfvil larvae are
rather abundant r. fin this year though apparently no worse
than usual. They are beginning to pupate at this date.

H. R. Bryson (April 23): The clover leaf weevil is slightly
more numerous than usual. Dr. R. C. Smith reports damage in
one field near Alta Vista. All sizes of larvae are present
in all alfalfa fields. Generally there is no apparent injury.
First cocoons were found April 11. One report from a county
agent states that this pest was injuring alfalfa in a field
at Clements. An infestation of 5 larvae per crown was ob-
served on a 2-year-old stand.

F7A APHID (Illinoit nisi Krlt.)

G. E. Gould (April 22): The pea aphid is moderately
abundant on alfalfa, but is still scarce on garden peas.

H. R. Bryson (April 23): Dr. R. C. Smith reports pea aphids
present, but in small numbers only, in most alfalfa fields.
lTo injury has been seen or reported. Only the winged forms
havd. boon seen so far. Growing conditions are excellent for
.t alfalfa now. Lady bird beetles, Hinpodamia convergens Guer.
and Adalia biunctata L., are plentiful. Dr. Z. G. Kelly
states that are increasing to outbreak proportions
at Larned and Great Bend. There is a slight outbreak also
at Dodge City.

24 Isely. (April 25): An outbreak of green pea aphids on
alfalfa has been reported from central and northeastern

R. W. Earned and assistants (April): Pea aphids were
collected on alfalfa at Pace on April 18, ind on Austrian
winter peas at Cleveland on April 19. Infestations were
spotted and in places very severe. The spcirn.-_ns received
were heavily parasitized.

L. P. Rockwood (April 2): Infestation increased rapidly
during March on early fall-sown vetch -nd Austrian peas where
the %aphids established themselves last fall and surviv,:d the
mild winter in viviparous form. They have become abundant on
cover crops in some orchards of Washington and YTmhhill Counties.
The fungus F-.tom- o0'1t-, anhidis Hollm:rn has checked them in
one orchard, but although present in other places it has not
been observed as epidemi- w A few Hippoda.:--ia con-.'ern-ens Guer.
have appeared in the fields and Coccinella trifasciata Lm ..
are present in large numbers in some old prane orchards, in or




near which they probably hibernated. Hippodnmia spuri Lec.
and H. ambigua Lee., which are hibernating together on a
bald hill in Ynirhill County, had not left their cache by
March 22, They are present in great numbers in this cache.
Some were affected by the fungous disease Beauveria globuli-
fera Speg. The first alate viviparous females ere found.
March 16, but very few and not many nymphs. There is as
yet no indication that late-fall-sown vetch and Austrian
field peas have become infested by I. pisi migrating from
early-fall-sown vetch.

ALFALFA CATERPILLAR (Eurymus eurytheme Boisd.)

H. R. Bryson (April 23): R. C. Smith reports on April 18
finding several nearly grown larvae of the alfalfa caterpil-

continuously for more than 50 years past. Beetles have been
injuring sprouts of cane and corn since the last week of
March but no egg laying occurred before the middle of April.
Adults were taken at trap lights at Franklin in considerable
numbers on April 16 and 17, when night temperatures of 60
degrees F. or higher prevailed. Mating and egg laying were
just beginning apparently about April 16. A few specimens
of Ligyrus gibbosus DeG. were also captured.

during the 1930 puapation season, the excellent 7pr2:'ing se-son
last year, and an unusual amount of jarring of trots are factors
which reduced the. curculio population. Ad:ults bt-*.n to appear
in orch'irds at Fort Valley in numbers April 4. In one
locality we took 87 from 5 trees. Only an occasional single
individual was found previous, to tills date, as 'ollows: March
26, 2; March 28, 1; April 2, 1; April 3, 6. Evidently they are
just be=-in::irgc to leave their winter quarters as a result of the

high temperatures recorded during the'liast several days.
They ars 1,iter lc:!ving hibernation this year than during
any of the 1ast 11 years. L-st year thcy began to leave
hibernation in numbers on ?!,.rch- 17, and that was considered
late. Year before last they began to leave hibernation the
first week in March. *The curculio should not cause a great
amount of damage this year. It is very doubtful if there will
be any second generation.

C. H. Alden (April 20): The first beetles of the plum
curculio were caught April 14. They are scarce at Cornelia
and moderately abundant at Thomaston.

J. R. Watson (Ar-il 21): The pluom curculio is scarce for

SULD CORY MAGGOT (Hylemyia cilicrura Rond.)

H. G. Walker and G. E. Gould (April 22): The seed corn
maggot is moderately abundant at Norfolk.

17W. J. Reid, Jr. (April 22): The seed corn maggot has not
been so serious a p-est of newly planted seed potatoes in
Pamlico County this season as in the average spring. Good
to excellent plant stands are bein, obtained in the commer-
cial plantings. (April 18): An unusually destructive in-
festation, of potato seed pieces by the seed corn maggot oc-
curred in the experimental plots at the Chadbourn field
laboratory. On one plot a plant stand of only 61 -er cent was
obtained, the missing hills being due chiefly to the insect
Injury. The heavy infestation is attributed to the use of
large quantities of organic fertilizers and to the failure of
the cut surfaces of the potato seed pieces to form a rrotect-
ive cork layer. A Fusarium decay attacked the cut surfaces
of the seed and was followed by the seed-corn-maggot injury.
The insect apparently hastened the spread of the fungus or-
ganism. The greater -art of the larvae feeling on the seed
potatoes occuned between March 15 and A'ril 15. At the
present date most of the maggots have left the seed and pu-
Dated nearby in the soil.. Adults are very abundant in the
field. A later planting of potatoes in an adjoinuin- field
has also been attacked. The outcome of this infestation is
uncertain at the -resent. As m'.-rny as 55 larvae were found
feeding on one seed nicce on April 18. These s-ecimens are
evidently of a second spring brood.

C. H. Brannon (April 20): The seed corn mrawY-ot is caus-
ing widespread damage to sprouting snar beans.

7. J. Reid, Jr. (April 6): The seed corn maggot has ap-
parently not been so destructive as usual to potato seed
pieces near Charleston this season. Good to excellent
plant stands aro beinc obtained. Observattions of the writer
indicate that the lar".} populationn of the insect is con-
sidcerably below norril.1. Thi- condition is attributed to
prolonged cold, 7indy reathcr during the z.u:-il oviposition
period of the insect, and a scarcity of suitable larval
food. Partly decayed or;'.nic matter in the soil constitutes


the chief food of the larvae./ Unusually dry soil conditions
during February and March resulted in very little decay of
the organic matter in' the soils at Charleston.

F. L. Thomas (April 20): The seed corn maggot is very
abundant in six counties in western Texas. April 10-16: Re-

,and broccoli on April" 9. These insects are quite abundant
this spring.

S.W. A. Thomas (April 21): The first specimens. of the
harlequin bu,g were observed on the flower stems.of turnips
at Chadbourn. Ordinarily these plants wold have been heavily
infested at this season of the year, but for some reason
there is a scarcity of this species this season.

J. -i. Watson (April 21): The harlequin bug is scarce.

J. M. Robinson (April 20): The harlequin bug is very
abundant on turnips, kale,and collards at Auburn and Seal.

IL W. Harned and assistants (April): The harlequin bug is

J. M. obinson (April 20): The strawberry weevil adults
were reported active at Planton and Jemison.

LESSML COmT STALK BO"LL (ElasmopalpTs lignosellus Zell.)

V7. A. Thomas (April 13): The lesser corn stalk borer is
doing serious d'a,'-Le to first-year strawberries near Chadbourn.
The outer leaves are usually attacked first and later the
fruit, stems, and crown are destroyed. This, insect usually
appears in late July and" Au:'Ust, when considerable damage is
done, but it. has never before been observed in this area,
injuring strawberries this early in the spring.

Notes abstracted from "News Letter," April, 1931

(Not for publication)

ORANGE MAGGOT (Anastrepha ludens Loew)

Mangoes brought to Mat-moros from the State of Michoacan, in the
southern part of Mlexico, were rather heavily infested with fruit worm
larvae; some 485 specimens were collected, most of which were from

PARLATORIA DATE SCALE (Parlatoria blanchardi Targ,)

The only finding of infestation in the Coachella Valley during the
month of February involved 4 palms in one of the infested plantings
which has no commercial value. These palms were dug out and destroyed.

PINK BOLL WORM (Pectinophora gossypiella Saund.)

During February, 1,064 samples, of 100 bolls each, were inspected
at the laboratory with negative results. These samples had been col-
lected in counties in Alabama, Georgia, Mississippi, and Texas.

GYPSY MOTH (Porthetria dispar L.)

All of the work in Dukes Park, N. J., was completed during the
second week of February and no gypsy moth infestation was found. Dukes
Park is the property where the original gipsy moth infestation consist-
ing of over 3,000,000 egg clusters was located in 1920. Infestations
have been discovered in the townships of New Marlboro, Sheffield, and
Sandisfield, Mass.

EUROPXA CORN BOBER (Pyrausta nubilalis ITon.)

The clean-up of isolated infestations of the European corn borer
on Manchester Island, Lewis County, and in Bradford Township, Bracken
County, Ky., is very nearly completed.



Insect conditions during March and April, 1931.

A very heavy infestation of a beetle borer (Apate francisca Fab.)
was investigated March 17 to 21 in the Barrio of Los Angeles at Lares.
where about 100 coffee trees on about 1 acre had been injured. Some
injured guaba trees had been cut down, and an, an "aii-.uncate"i'
and some "pomarrosa" fence posts had also been slightly injured; burrows
made by the beetles were found also in two "achiote"t trees. In a
pigeon pea planting in the Barrio of Espinosa 50 infested plants had
been cut and burned. By the first week in April on the occasion of the
next visit to Lares, no further injury had been reported and the outbreak
had apparently almost subsided. (Mr. Sein)

The moth stalk borer (Diatraea saccharalis Fab.) is-generally rnich
more abundant than previously because of the change of variety of cane
grown, the B.H. (10) 12 now extensively grown being softer and sweeter
and more susceptible to infestation. This is despite the rather general
adoption of nonburning. of trash, which favors Tricho-raia. Of course
the trash must be burned in preparing the land for planting, and as
less cane is ratooned, the areas in which trash is left on the fields
are more limited in extent, especially on the south coast. (G.N.Wolcott)

In the region on the south coast between Ponce and Guayar.a, white
grubs (Phyllophaga portoricensis Smyth) have been much less abundant
since the hurricane in 1928 than they were previously, and the sane is
also true of the weevil root-stalk borer, Diaprepes abbreviatus L.
Mr. Osborn has reared two previously unknown egg parasites of the latter,
but the parasite situation, so far as white grubs is concerned, is
unchanged. Cultivation practices, however, have been greatly c.ano-ed,
about two-thirds of the area being plant cane, and only about one-third
is ratoon. Subsoiling with sten.^ plows is standard practice now, which
definitely kills grubs by crushing them, while with less thorough
preparation only grubs actually cut by the plowshares were killed.
Rainfall has been much more abundant, which possibly may have had some
effect. (G..:T.olcott)

Reports and observations indicate that the tobacco leaf-miner
(Phthorimaea operculel-la Zell.) has been doing considerable drn-aCe, more
so than usual, to fields of tobacco in Comero and Caguas, and also in
one 3-acre field near Rio Piedras. Unusually dry weather is undoubtedly
the cause. (M. D. Leonard)

A light infestation of the red-striped sugarcane scale (Pulvinaria
iceryi Guer.) on the leaves of some sugarcane plants grown in one of the
greenhouses of the Insular Experiment Station at Rio Piedras was found
on March 26. (M. D. Leonard)

A large citrus grower reported that about one-third of 30,000
grapefruit seedlings in his nursery at had been killed by white


grubs (Phyllophaga, probably citri Smyth) (M. D. Leonard.)

A light infestation of the lima bean pod borer (Maruca testulalis
Geyer) on blossoms and pods of lima beans in a 2-acre planting at Jurna
Diaz was observed on March 13. (A. S. Mills.)

A leaf beetle (Ceratoma denticornis Tab.) was fairly common on the
string bean plots at the Experiment Station at Rio Piedras, but doing
litle damage. (M. D. Leonard.)

A leaf beetle (Diabrotica graminea Baly) was reported by Pedro
Osuna of the Insular Experiment Station as fairly abundant on about
1 acre of Irish potatoes at Comerio and on about 5 acres at Adjuntas,
early in March. This insect was also reported by A. S. Mills as
moderately infesting a 1-acre planting of okra at Trujillo Alto on
March 27, the beetles feeding on both leaves and flower buds.
(M. D. Leonard.) ....

The potato flea beetle (Enitrix cucumeris Harr.) was present in
increasing numbers during January and February and very injurious in
March in several 'fields of potatoes in Cor:merio, Adjuntas, Cidra, Caguas,
and Rio Piedras, according to Pedro Osuna, of the Insular Experiment
Station. (M. D. Leonard.)

Under date of March 19 a report was received from Humacao saying
that considerable damage was being done to plantings of sweet potato
there by Cylas formicarius Fab. (M. D. Leonard.)

A leafhopper, Empoasca jabanae DeLong, was abundant on string
beans in experimental plots at the Insular Experiment Station at Rio
Piedras throughout the month, becoming more destructive towards
harvesting at the end of the month. (M. D. Leonard.)

A small garden patch of Irish potatoes was reported by Pedro Osuna
as badly infested by Myzus persicae Sulz. on March 31; many of the leaves
were curled. (M. D. Leonard.)

Specimens of a bug, Spartocera batatas Fab., were received for
determination from Utuado from Agricultural Agent A. Correa, who stated
under date of March 20 that they were injuring the experimental plots
of Irish potatoes. This is apparently the first report of injury to
Irish potatoes by this insect in Porto Rico. (M. D; Leonard.)

Mr. E. F. Roarke of the San Juan Ginnery Company reports that the.
cotton leaf worm (Alabama argillacea Hbn.) was starting to work in one
field of cotton at Iso.bela. This is the first infestation observed
on the north coast in this year's crop. No infestations were reported
during March for the south coast. (M. D. Leonard.)

Counts made on the pink boll wvorm (Pectinophora gossypiella Saund.)
by several of the local agricultural agents on the south coast, examining


100 mature but unopened bolls in each field, showed the following per-
centages of infestation:
March 10, Lajas (3 fields) 85 per cent, 18 per cent, 24 per cent
March 10, Sahana Gr-,nde (1 field) 16 per cent
March 10, San Germnan (1 field) 38 per cent
March 11, Cabo Rojo (2 fields) 80 per cent, 84 per cent

Heavy infestations by Dysdercus andreae L. were reported by M.essrs.
Mills and Faxon of the Plant Quarantine and Control Administration in
fields of cotton at Ponce, Guayanilla, and Penuelas on March 13,
(April 16): The pink boll worm is becoming more abundant on the south
coast. (M. D. Leonard.)


Notes on observations during March and April, 1931.
By U. C. < Loftin.

On March 15 we received a complaint that cane was being damaged at
Central Cuba, Mantanzas Province. The insects proved to be Cirphis
latiuscula H. S.. and an undetermined Lepidopterous larva. On March 30
another complaint was received from Central Socorro that C. latiuscula
was damaging cane. This is unusually early in the season for the
grassworms, as they generally do not become abundant enough to attract
attention until after the beginning of the rainy season, or in the
latter part of May or early June.

A field of velvetbeans on the Station grounds at Central Baragua that
were planted last November are nearly mature and are being turned under
for green in.ure, A very light infestation of the velvetbean cater-
pillar (Anticarsia gemmatilis Hbn.) was noticed last December, but
since that time the beans have not been attacked by this pest.

On March 19 young corn at Central Jaronu, Cztux.guey Province, was
heavily infested and badly dmaged by Laphyg frugiperda S. and A.
