OUTSTA2TDITG EIT'.o.:OLOGICcAL F7 TURhS IN, THESE UNITED STATES FOR OCTOBZR,1931

Despite the very late appearance of the cotton leaf worm in the Gulf
Region, the roths of this insect did some damage to fruit in centr-.l Mis-
souri and southeastern Nebraska. The only other records we have of flights
of the moths into the North was a report from Michigan that a single speci-
men was collected on October 21 at Shelby.

The plains false wireworm- is doing considerable damage to the nc'.'ly
planted wheat in western Kansas.

The Asiatic beetle severely damaged lawns at points in Connecticut and
New York.

Soil surveys m-nade during Septc-ber indicate that the Japanese beetle
infestation is definitely heavier than it was this spring in the Moores-
town district in New Jersey, and in the Jenkintovin district in PBnnsylvania.
These surveys further indicate that this insect is ;e'-,2raolly distributed
as far northward as Plainfield and Metuchen,N.J., fith loc!1lieod colQ--Aes be-
yond this region.

Grubs of the scarabsaid Ochorosidia villosa Bur7. were reported as
having very seriously d-a:ed the turf on the fairways of a country club
at Bayvsidc, and lawns ,t Lawrence and 7o0od~ere in cw" Ynrc. 7e also have
a report of a lawn being ruined by this insect in the suburbs of >.'a-ii:-
ton, D. C.

In the East Central States an unusually heavy emergence of the Hessian
fly occurred in September. In -ost places, however, this was too early to
infest the wheat sown after the fly-free date. V'lmunteer "'heat, thou, h
scarce, is heavily infested.

... The corn ear worm persisted extrc--ely late in the northern States. In
Maine this insect was more nur-erous than has been observed in the -ast ten
years, and similar reports of unprecedented infestations occurred as far
west as ,isconsin, Mi.mesota, South Dakota, and Iown. It not only ..i.-ed
late sweet corn but also ate the nature field corn and did very- considerable
damage by entering greenhouses, where the larvae attached. -oractically all
forcing plants.

The chinch bug maintained a population in the ast Central States
of such proportions that the number of bugs going into hibernation is
distinctly alarming. This insect has also been re-oorted from east-cen-
tral Pennsylvania.

The fall armyworm was re-ported during the last few days in Septem-
ber from the lower Gulf region in Louisiana, where it was damaging soy-
beans and sugarcane. This insect was also. reported as a pest to flowers
growing under glass in Michigan. .

At harvest time side-sting injury by the codling moth was observed
to be unusually prevalent throughout New -England and the Middle Atlantic
States. Similar injury extended across the lake region into Minnesota
and Iowa.

Apple leafhoppers were so prevalent at harvest time in the orchards
of New England, the Middle Atlantic States southward to Virginia, and
the East Central States westward to Illinois and Kentucky, that these in-
sects,in addition to spoecking the fruit, were a very decided nuisance to
the pickers.

The citrus whitefly was reported as quite generally abundant from
Georgia and Florida to Mississipp-oi.

Along the Atlantic seaboard, from Virginia southward to South Caro-
lina and Alabama, the cabbage webworm has been doing very appreciable
damage to cruciferous crops. This insect is also occurring in damaging
numbers on cauliflower in southern California.

The pickle vorm, during late fall, appeared in the Middle Atlantic
and New England States in greater numbers than it has in many years.
The first record of this insect as a -oest in Connecticut was made this year.
The insect was so numerous that practically no squash was harvested in
the Charleston section of South Carolina, and many fields of late cucum-
bers were completely ruined in north-central Florida.

The cabbage looper is reported as damaging spinach in Ohio and Penn-
sylvania.

The birch skeletonizer is heavily defoliating birch in Maine, New
Hampshire, and northeastern New York'. This insect has also been re-
ported from Wisconsin and Minnesota. The birch leaf-mining sawfly is
also seriously infesting birch from Maine to northern New York..

The boxelder bug is very unusually prevalent in Virginia, '.aryland,
and Delav-are. This insect is also reported as very prevalenIt in the
3ast Central States, 'Jest Centrl.1 States, Utah, an. 7ashington.

Damage to azaleas and rhododendrons by white grubs is becoming' in-
creasingly prevalent in s-uthorn labama where these o-lants are used
very extensively as orna-nentals.

The Eur.pcnn thrips Taeniothrins atratus montanus Priesner is
recorded for the first time in the United States. It was found this sunm-
mer on gladiolus at Lon-ncadow, Mass ..-. .

GENERAL FEEDERS

GRASSHOPPRS (Acrididae)

*F. S. Chamberlin (October 8): Grasshoppers, mainly Melanoplus
sp., are more abundant than usual in Gadsden County for this
season of the year.

J. R. Watson (October 25): Grasshoppers are moderately
abundant and are doing considerable damage to young citrus
trees in the northern and central parts of Florida.

J. J. Davis (October 24): Grasshoppers were reported abundant
and destructive in tomato fields at Sulphur Springs, Henry
County, October 7.

W. P. Flint (October 24): While grasshoppers were only
slightly more abundant than usual in the State this year, they
have had ideal conditions for eg,.-,laying during the fall and
we anticipate serious damage next year.

C. Benton (September): Grasshoppers are locally abundant
near FaTetteville but no commercial damage has been reported,
largely owing to the fact that on account of drought the usual
September plantings of small grain and lenumes were not made.
Much volunteer wheat has been eaten up by them.

E. L. Chambers (October 27): Grasshoppers are moderately
abundant but still quite numerous in certain sections.

A. G. Ruggles (September 26): Grasshoppers are gradually
dying off, but egg laying continues by those left, on sides
of roads, ditch bans and edges of fields, and parts of
pastures are filled with eggs in the infested area of the Red
River Valley. Adults are still numerous enough around Stephen
to eat off several acres of fall rye down below the surface of
the ground. We can not see what will prevent a big outbreak
in 1932.

C. F. Stiles (October 28): Most of the grasshoppers have
laid their e,-s and disappeared from Oklahoma. With favorable
weather for development of grasshoppers, we may expect a serious
outbreak in central and southwestern Oklahoma next year.

H. C. Severin (October): We have not had a killing frost as
yet, and surviving grasshoppers are still laying eggs. The
species surviving in largest numbers are M. differentialis Thos.,
M. mexicanus mexicanus Sauss., and M. femur-rubrum DeG.
M. bivittatus Say is an earlier species, and while it was the
most ha..ful of the four mentioned, it began to die off late
in August, and only a few survive at present. An immense number
of eg's are found in the ground in the areas that were badly

c. a-ed this year, while in much of the remainder of the State
the eggs are sufficiently abundant to cause alairrr. If weather
conditions will favor the grasshoppers this winter and next
spring, the d -..-ed area in South D-aota promises to be much
increased.

H. E. Jaoques (October 25): Grasshoppers have been moderately
abundant in many parts of the State. Many may still be found.
Late garden crops and other vegetation has suffered from th>m.

L. Baseman (October 22): The red-legged and differential
grasshopoers have continued in goodly numbers, ovipositing up
to the middle of October.

H. R. Bryson (October 24): Grasshoppers are moderately
abu-ndant in most sections of the State. Practically no damage
has been reported during the past month.

M. H. Swerik (October 24)? Grasshoppers have largely
disappeared now, having laid eggs.

C. Lyle and assistants (October): The only report of grass-
hopper damage during October was to soybeans at Cruaer. (Abstract,
J.A.)


COTTON LEAF '"OR:. (Alabama argillacea Hbn.)


Michigan



!4issouri


iebraska



MlIississippi


West Virginia


R. H. Pettit (October 24): A single specimen was taken on
or about October 21 at Shelby. This constitutes the sole record
for this year up to the present time in Michigan.

L. Haseman (October 22): Cotton leaf worm moths have continued
abundant and injurious to fruit at Columbia all this month.

M. H. Swerik (October 25): A small flight of moths reached
Nebraska during the first week in October, and were complained
of at that time as damaging ripe peaches in Cass County.

C. L7le and assistants (October): The cotton leaf worm is
unusually scarce throughout the State this year, the infestations
being so ]i'ht that no control measures were found necessary.
(Abstract, J.A.i. )

ITZIE GPJJBS (P-llopp--.ra spp.)

L. 1. Peairs (October 24): White -mrbs are very abundant
In laws at Parkersburg.

T. H. Parks (October 24): Several complaints reached this
office during Septem.ber of white grub injury occurring to
lawns in Columbus.

A. A. Granovsky (September 27): White grub's are very abundant.
A few lawns in Minneapolis are badly infested with Brood B larvae.

L. Haseman (October 22): White -rubs are reported at Columbia.
Still abundant in first 6 inches o0 surface soil.

M. H. Swen: (October 26): nWhite grubs continued to be observed
actively feeding until about October 23.

WI R S0PS .( Elat eri dae)

C. A. Thomas (October 20): 7Wireworms cau-sed considerable
injury to potato tubers on several farms in Pennsylvania this
su,..-r, reports coming from'-Erie, Crawford, Huntingdon,
Lycomning, Chester, and Bucks Counties. In southeastern
Pennsylvania the chieLf injury was by larvae of Pheletes agonus
Say while in Erie County a Melanmotus larva was the chief
offendCer. '

J. J. Davis (October 24): Wireworms were serious pests of
potatoes in several localities near Evansville according to
report sent October 17.

State Plant Board (October 26), Wirewo a injury to sweet-
potato tubers has been reported d(.rinig October as rather serious
in Jackson, Monroe, Lauderdale, Rankin, Copiah, and Bolivar
Counties.

C. F. Stiles (October 28): Wireworms are damaging some
fields of wheat in Alfalfa County.

E. 0. Essig (September 28): Wireworms are moderately abundant.

PLAINS FALSE WIRVOsM (mEeodes opaca Sa.y)

H. R. Bryson (October 24): The false wireworm has been doing
consi derable djnage in the western part of the State. Owing
to the dry su-mmer aTid an extended dry fall, the larvae have had
the advantage of a long feeding period. Wheat sown in September
has not --ad sufficient moisture to insare its germination, hence
much damage has been. done. A few reports of 100 per cent
damage in some fi.elC have been received. Re-ports in correspondence
iave been received from Copeland, Delphor, John.son, Healy, and
Hoxie, 'ns. At the time of this writing no t'r lr.c*rItures
sufficiently low-to force the larvae down into the soil for the
winter have oe.o..rred.


ASI.T1IC 1^S 1'1 3MSTLE (Asorica castey:oa A.^ow)


C. H. Eadley amd assistants (U.S.D.A., Japanese Beetle Laboratory)
(September): This beetle has caused more turf injury during the
fall than during any previous year since the investigation was .
started in 1927. This injury occurs on the lawns in the northern

half of lT3ssau County on Long Island. Althoi--h adults are still
to b e found in the field, they are scarce.
During the month a total of 139 soil surveys of one square
foot each were made at Chestnut Hill, Pa. An average of 8 rubs
to the square foot was found with a ra:,:.e of 0 to 93.

ASIATIC B-TLE (Anomala orientalis 7Taterh.)
R. B. Friend (October 24): Several lawns in the Westville
section showed severe injury this month, but in the center of
the infested area the insect is less abundant. A severe
infestation appeared this year about 1-I miles outside the
quarantined area. The insect is not spreading rapidly.

C. E. HadlLy and assistants (U.S.D.A. Japanese Beetle Laboratory)
(Septcmber): The turf injury at Jericho, reported in August has
spread so that it now covers about three-fourths of an acre.
The grubs have also attacked a stra'aberry bed (approximately
2,000 square feet in size) at the same place and destroyed 60
per cent of the plants.

JAPAITES? BE7TLE (Popillia japonica NTewm.)

C. H. Hadley and assistants (U.S.D.A., Japanese Beetle Laboratory
(September): Comprehensive soil surveys made in golf courses
at Moorestown, NT. J., and Jernkintown, Pa., show that the grub
infestation is definitely heavier than it was this past spring.
Field work on the distribution of the adult Japanese beetle was
continued during the first week of September, during which time
the region extending from ITe"m Brunswick north to Hac:ensack,
Paterson, and Newark was scou-ted. The results obtained indicated
the extension northward of the region of continuous occurrence
as far as Plainfield and Metuchen, and beyond these points, the
presence of usually highly localized colonies of the beetle in
-mn-- of the cities and towns occupying the belt of lon country
east of the Watchung Mountains.


A SC. 3.A:ID BEETL3 (Ochrosidio. villosa 3,-m. )


NTew Yore


C. H. Hadley and assistants (U.S.L.A., Japanese Beetle Laborator,
(September): Ochrosidia villosa: In the fairways of a golf
club at Ba-side, T. Y., approximately 1 acre of turf was destroyed.
The ruined turf was in irreglar spots which were widely separated
in different parts of the course. At La-':rc-.ce, N.Y., one-fourth
of r3 acre of lawn turf was entirely dcstr:--"c so that dead
brown sod could be easily rolled back. At Woodmere, Y.Y., 300
squre feet o' lawn was ruined.

F. L. Campbell (October 1): Toward the end of September
this insect was observed in very great k) "".:Ice in the Rodc

destroyed a recently sodded' o-..


CONMON RED SPIDER (Tetranychus telarius L.)


Ohio


Minnesota


Utah


Washington.


E. W. Mendenhall (October 21): The red spider mites are
very bad on arborvitae evergreens in a nursery near N\ew Carlisle,
Evergreens in one of the nurseries in Ashland are badly
infested.


A. G. Ruggles (September 26): Red spiders are very abundant
on raspberries, zinnias, apples, etc., throughout the State.


G. F. Knowlton (October 13).: Red spiders are still damaging
sugar beets in many Cache Vallecy fields.


M. A. Others '(October): During. the season the common red
spider has been the most abuondant and in-.jurious the orchardists
can recall in- the Wenatchee district. It has been particularly
injurious to the Delicious apple trees (foliage and fruit).
The unusually mild winter of 1929-30, '
th.e early spring', and the mild, dry su mmer were doubtless
conducive to maximum development of this pest.
In migrating to the soil in late summer and early fall
countless numbers of' the mites were caught and killed in the
chemically-treated codling moth bands and in tree tanglefoot
bands placed about the tree trunks.

CEREAL AND F0 RAGE-OROP I T SECTS


WHEAT
HESSIAN FLY (Phytophaga destructor Say)

T. H. Parks (October 25): Nearly all eggs were hatched by
October 25 and the newly emerged larvae were found attached
to the stalk under the leaf-sheath. Infestation exists at
Columbus in wheat sown immediately after the recognized fly-
free date. October was warm and late-sown wheat is getting
a good start. The majority of the fields are free from in-
festation. In this part of Ohio practically no wheat was
sown before the safe sowing dates.

C. M. Packard (October 5): Volunteer wheat from Logansport
to Evansville has 50 to 75 per cent of the stems infested.
The fly is largely in the flaxseed stage, with about 15 per
cent pupating. A few eggs and some newly hatched larvae are
present. Volunteer wheat is not very abundant. Not much
sown wheat was above ground by the last of September.

W. P. Flint (October 24): An unusually heavy emergence oc-
curred late in September. In many of the counties lightly in-
fested at the time .of stubble survey, the fly is now numerous
enough to lay large numbers of eggs on volunteer and early-
sown wheat. From the information at hand, wheat sown on the
recommended fly-free dates has escaped any serious infestation.

J. H. Bigger (October 13): Adults were numerous the last
week in September extending to about October 7 and 8. Exami-
nations on October 9 and 10 show:

Four fields seeded before October 2--60.4 per cent
with eggs
Two fields seeded after October 7---7.5 per cent
with eggs
Recommended date of seeding in this(Morgan)County
October 2

R. Hutson (October 23): The Hessian fly is moderately abund-
ant.

H. E. Jaques (October 25): The Hessian fly is moderately
abundant in Monroe Co0nty.

L. Haseman (October 22): Very little Hessian fly in ex-
perimental plats at Columbia; no complaints from farmers.

C. Benton (September 28): There is a light infestation in
volunteer wheat in the vicinity of Fayetteville. Mostly in pu-
parial stage, but a few eggs and newly hatched larvae. Slight
pupation in both stubble and vyolunteer-grain.. Hot, dry weather
has prevented.'most'.of the usual sowing of small grains for fall
and winter pasture.

M. H. Swenk (Septeinber): The summers and falls of 1930 and
1931 were se hot .and dry in eastern--Eebraska that the Hessian
fly was affected.-adversely, and in September, 1931, no special
menace of an outbreak seemed to be present." Evidences of the
fly in moderate amounts were reported from Xemaha, Otoe, Colfax,
and Dawson Counties during the month, "

WHEAT JOIT WORf (Harmolita tritici Fitch)

L. Haseman (October 22): The joint worm of wheat was re-ported
from Polk County.




CORN EAR WOMi (Heliothis obsoleta Fab.)

C0. R. Phipps (October 26):: The corn ear worm is very abundant
throughout the State. The largest number for 10 years have been-
sent in. .

L. C. Glover (October 23): The corn ear worm is moderately
abundant. '

A. I. Bourne (October 26):' The corn ear worm was, as usual,
quite abundant on late harvested corn. The unusual interest
in this species can be explained partly on the basis'of the
interest in corn insects of all sorts by the extension of the
European corn borer quarantine, which caused growers to scrutin-
i..ze their corn more carefully than would otherwise have been the
case. At the same time, however, from our own observation we
were led to believe that there was rather moreinjury from this
species than is usually the case..

W. E. Britton (October 24): The corn.ear worm is abundant in
all portions ofthe State.

A. E. Stene (October 21): The corn ear wormn is moderately
abundant.

P. J. Parrott (October 23): The corn ear worm is moderately
abundant in the western'part oi the State..

ported as doing considerable damage in plats of sweet corn in
the vicinity of Millbrook and Stockport.

T. L. Guyton (October 22): The corn ear worm is moderately
abundant and general over the eastern part of Pennsylvania.

L. M. Peairs (October 24): Corn ear worms are very abundant at

Mason County.

H. G. Walker (October 27): The corn ear worm is very abundant
on snapbeans in Norfolk.

J. R. Watson (October 25): The corn ear worm is moderately
abundant and is feeding mostly on seeds of beggarweed.

J. J. Davis (October 24): Corn ear worms have been unusually
abundant. From Mt. Vernon, September 28, report comes that this
insect ruined all of. the late sweet corn. Similar reports could
be given for many other sections of the State. October 17 to
20, reports were received from Monticello,.Rensselaer, LaPorte,
and Lafayette, of large numbers of earworns in alfalfa fields,
and apparently .causing appreciable damage. Ear v:orms were re-
ported abundant and destructive in tomato fields at Sulphur
Springs, Henry County, October.7.

W. P. Flint (October 24): A heavy flight of adults has con-
tinued. Several re-orts of damage to alfalfa (newly sown) have
been received.

J. H. Bigger (September 15): Corn ear worms are very abundant
in central and west-central Illinois. From 30 to 35 per cent of
the ears in six central counties are infested.

W. A. Price (October 24): The corn ear worms are still feeding
on corn that is ready to go into the crib. They are tunneling
the kernels, feeding on the germ. Much damage is caused by the
activity as all kernels so eaten fall off the cob and are a total
loss. Also the worms continue to be troublesome in dahlias at
Lancaster, Lexington, and Owensboro.

R. Hutson (October 23): The corn ear worm is very abundant;
there are large numbers of moths.

J-ROPrA2I COPRl BORER (Pyrausta nubilali s Hbn.)


Connecticut


W. E. Britton (October 24): A recent survey shows a rather
heavy infestation of stalks in East Lyme, Groton, New London,
and Old Lyme, with lesser infestations throughout New London,
7indhamn, and Middlesex, and portions of Hartford and New Haven
Counties. The survey did not cover the other portions of the
State.

Sudan grass in Catawissa, and they also have been reported doing
da-age to corn, oaths, and young grass.

7. P. Flint (October 24): The chinch bug population in the
central part of the State has built up very strongly during the
latter Dart of the summer. At present there are enough bugs in
hibernation so that we will have serious dLamage extending from
McLean and Hancock Counties, on the north, southward to a&,7hing-
ton, St. Clair, and Jefferson Counties on the south.

J. H. Bigger (October 13): Chinch bugs have been flying into
hibernation in western counties. A recent survey has indicated
wide spread this season north and west to Bloomington and Jack-

SOYBEAN

VELVET3EA:7 CATERPILLAR (Antioarsia gem-natilis Hbn.)

W. A. Dokiglas (September 29): The first injury to soybeans
was found on Se-otemnber 15. The infestation is at present very
light and it is not expected that control measures will be
necessary, as most varieties of soybeans are practically mature.
This insect has appeared later each year since the first ap-
pearance in 1929 and each year the injury has been less severe.

State Plant Board, Press Release (October 26): The southern
grass worm, which was so abundant in the fall of 1930, was con-
spicuous by its absence this year, being reported abundant in only
one case in Attala County.

S. Lockwood (July 27): This noctuid larva has been responsi-
ble for very severe damage to field and sweet corn on about
1,000 acres in the Mission and Tia Juana valleys of San Diego
County. Re-ports have come to this office that seem to indicate
that this same condition exists in parts of Los Angeles County.
The later sweet corn will be entirely mruined and the tonnage of
the field corn will be cut severely. It is not uncommon to find
as hih as four or five vworms to one corn plant. (October 5):
This insect has been more than normally abundant this fall. The
trouble has extended as far north as Monterey County, w-here this
worm has attacked lettuce and tomatoes.

W-732'701S (Crambus spp.)

J. S. Houser (October 5): There were v:ery heavy catches of
cr:'mbids in light traos throu,-hout most of September.

J. J. Davis (October 24): 7ebvorms continued to be occasion-
ally reported. Small worms, probably of the third se-Lso-al
generation, were -:mi:,n lawns at Bluffton (October 3) and Con-
nersville (October 12). The underground tubers of carrots were
seriously eaten into by a webworm at Ft. 7.,ne, October 5.
Adults have not yet been reared.

T7. B. Noble (September 21): Half-grown larvae are abundant in
greens on a golf course near Lafayette, also common in one other
grassy area examined, but in these locations most of the larvae
were dead; apparently killed by bacterial diseases, the hot humid
weather during most of September having been favorable to such
a developm)cnt. Possibly these diseases mean the end of the past
season's outbreak and may be an important reason why such out-
bre.kcs are so infrequent.

7. P. Flint (October 24): Several cases of do7.e in green-
houses have been ro-oorted durini the -oast two weeks.

J. H. Bi^.--r (October 13): Sod webwor-s, C. trisectus Walk.,
flew in large numbers in western Illinois during the period of
Aukist 20 to Sept, -ber 1, or after.

M. L. Didlako (A._-'..:t 25): Specimens collected in Fayette
County, August, have been identified -s C. mutabilis Clem-. and
C. teterrellus Zinck. Specimens reared in the laboratory- from
worms collected in Fa ctteCounty, July 15, as C. trisectus '.7alk.
and C. teterrellus Zinck.

ville, September 10 20.


A DIGGER BEE (Andrena asteris Robertson)


West Virginia


'. W. Craig (October 2): A digger bee was reported attacking a
lawn at Charleston on October 2. The soil was of the sandy type
along a terrace on the river'bottom. One small lavn... was honey-
combed with burrows and piles of sand so thick. that they over-
lapped and bees were in a swarm overhead. Neighboring lawns have
a few also.* (Det. by G. A. Sandhouse, Oct. 23.)


SUGARGAkE

SUG,..RCA:~.. BOIR (Diatraea saccharalis Fab.)


Louisiana


J. 17. Ingram and E. K. Bynum (September 29): Infestations in
sugarcane showed a normal increase during the month of September.
At the end of the month the infestations ranged from about 5
per cent to 80 per cent bored stalks.

cial orchards. There wE.s a very s-: 1l third gneration in
Lawrence County compared with last season. There are r.unmerous
stings on fruit on the hill orchards, but few live worms have
survived the spray program. The growers have made a big effort
to control the insect and did more thorough summer spraying
than ever before.

Monthly 1News Letter, Los Angeles County Agr. Comm.
(September 15): The Mexican mealybug P. gossypii is rapidly
becoming a serious pest pf ornamentals and certain garden
crops in Los Angeles County.
This mealybug has attracted particular attention as a pest
of ornamentals and. is atvery omnivorous feeder. Cosmos,
chrysanthemum, aster, dahlia, Australian pea, hollyhock, Ivy-
geranium, and many others have been killed by its attack.
Among wild plants, sunflower and cocklebur carry very heavy
infestations. It has been known to severely injure small

and a number of related plants are also hosts. Proximity to
plantings of ornamentals seems to be the source of field-crop
infestations which would probably limit its seriousness as a
pest of commercial acreage.

Some citrons growing in a citrus grove in Polk County.
Besides the citrons, they were attacking mid-.season varieties
of oranges, but not the late varieties. This is the first
instance of this insect being of economic importance that has
been brought to out notice in Florida. L. phyllopus L. is
always abundant and injurious, and is now doing some daar.e
to satsuma oranges in Alachua County. The citrons involved
in the outbreak were the cucurbits, not the citrus citron.

(September 15): Young citrus trees, mainly oranges, have been
damaged to a conr.-: i3rable extent this season by various species
of fire ants (Solcnr.opsis). Damage has not been entirely
confined to citrus, as the ants have been found working at the
base of aster plants in connection with the aster root aphis;
also on peach trees.

this insect that I have ever.% seen or had reported in
Connecticut. Until now we did not have an. adult in 'or
collection. It is attackin- cucumber and sui.ner squash at
Branford, Ha -den, and Greenwich.

E. Y. Cory (October 22): Diaphania nitidalis was reported
on squash in Baltimore County.

fall squash plantin":s at Clharleston by the pickle worn and
the melon worn ( 7. h.-alinata L.), reported in September,
hA,s contine-.c. throughout October. Inju-r, to the fruit has
been quite general. No squash whatever has been harvested
in this section fror.im tnpoisoned plantings. In most instances
plants in unpoisoned.fields are now. entirely dead as a result
of the insect attack. A second fall -eneration of both species
appeared in the middle of Oct'ober. Adv.lts of both species'
.iere abo.d.nt in the field throughout October.

J. R. Watson (October 23): The pickle worn is unusually
dcetractive to fall-7rown cucu-.ibers in the north-central
part of the State. Some fields have been utterly destroyed
in a week's tine. The caterpillars mine the entire ster of
the plart. Squashes have not been so severely injured.

F. S. Chanberlin (October 12): The pickle worm is very
destructive to cucurbits in Blountstown at this time.

W. J. Reid, Jr. (October 21): Fall cucu.n3oe.r plantings in
the vicinity- of ;7auchula, Hardee County, are being severely
daaged by the pickle worn and the melon worm, D. hyalinata L.
The worms are feedin- on buds, leaves, vine stems, and fruit
of all sizes. All plantings are apparently infested to some
extent, as much as 75 per cent of the fruit being rendered
unfit for use. Complete abandoinment of several fields by the
growers has occurred. Feedin; of the worms on the vine stems
is quite general. Growers of the county estimate that their
1931 fall cucu-iber crop of approximately 600 acres will be
cut 50 per cent. The pests are much more destructive than
usual this fall.

several localities between Skorhegan, Guilford, and Monson
showed 25 to 50 per cent of the foliage mined with occasional
trees showing possibly 75 per cent of the foliage affected.
From Monson to Greenville and Binjham to Jockmaen from 20 to
25 per cent of the foliage was mined. Bucculatrix infestations
are severe in these localities.

J. V. Schaffner, Jr. (Seotember.24): In the White Mountain
section of 17ew Harmpshire the birch foliage, especially on the
mountain sides, is badly browned by the B. canadensisella. The
skeletonizer seems to be largely responsible for this condition
though some of it is due to the great abundance of aphids.
T. H. Jones noted a heavy infestation of about 2 acres in a
growth of small gray birch at Exeter. This was the only instance
of injury noted in this section.

R. D. Glasgow (October 26). The birch in northeastern New
York and including the greater part of the Adirondack area has
been severely injured this year -und in many places completely
defoliated by the middle of Septcr.bcr, through the work of one
or both of two insect pests, rn-ely, B. canadensisella, and

PE: 30LI, 7.:TCP' (Pectirophora gos'..:iella Saund.)

Within the related area 32! rushels of trash were e-amined in the
Salt River and Gila Valleys of Arizona. The results were all neg-ative.
In t-he 3i- of Te:-,s the first bale was gin.ed on Auust 15, and 79
larvae wer: teen from three-fourths of a 'cushel of trash. The second
bale was pinned on Auguist 29, and from one-third bushel of trash 353
pin: boll worms were talen. On Augst 31, 471 pink boll worms were
taken from 1 bushels of trash. This makes a total of 854 specimens
taken from 2-1/3 bushels of trash.
The regular weCd:>l- infestation counts from 23 selected fields in
Maricopa and Pinal Counties, Ariz., were continued throughout the month
of Auguast. A total of 23,600 bolls and 5,000 squares were exasnined;
also 1,690 bolls from fields which had been found to be infested during
I.y and June. The results of al] the above examinations were negative.
In the Tucson area 875 Acres were inspected. This makes 2,100 acres
which have been covered. There still remain some 400 acres to be in-
spected, which will cor-plete the entire*acreage in this district.

*JAPAITSE _-- :T: (Popillla Japonica YTewm.)

For the first time since the Japanese beetle has spread to the
blueberry sections of the pine barren region of e[ew Jersey, it has been
necessary to fumiat blueberries as a requirement for their certification.

This season's co'.tinr activities in the vicinity of the clay pits
centering around :c'. Brunswick, IT. J., rev-' -led initial infestations in
practically all of those establishments in which Janr"ese beetles iad'
not heretofore been found.
T'.,t Japanese beetles in Connect- cut fly hi'-h .:s shown when 69
were collected off the roof of a clubhouse in IZew London. Report
received by one of the men looking after the traps in that city, indi-
cating presence of beetles about the club, led to the se?.rch which
captured the specimens. Tv;) b-etles also were cam-Lht in traps placed
on the roof of the clubhouse.

GIPSY IMOTE (Porthetri' disar L. )

Leven rc lar scouting crews were enr3-ed throughout August in-
spectin7 extensive wooden areas in six townshipr in the Adirondack
reo'-on of thelio barrier zone, nancly, Chc serfiel, Crown Toint, EFsox,
Ticondcroga, Westport, and Willsboro, N. Y. Scven ::'.w York Conserva-
tion Departmnent crews .rc scouting in the townships of Canaan,
Austorlitz, and Hillddale. YTo indications of ...syr moth infestations
were reported by either F:deral or State forces op1rating in the barrier
zone during Autrnst.

Four ITew York State crews were scouting in the township of ITorth
Hempstead, Nassau County, Long Island, and have reported the discovery
of one infestation, but inasriuch as no clean-up work has yet been done,
it is impossible to determine the extent or intensity of this infestation.


MXICAIT FRUIT FLY (Anastropha. ludons Loew)

Operation of approximately-1,100 fly traps in the groves on the
American side of the Rio Grande resulted in the capture of two specimens
of A. palleus Coq. during th.e Month of.August. One of these was..- taken
in a grove near mission on the llth, and the. other,.was taken in a grove
on the outskirts of Brounsvilla on the 8th. It will. be recalled that
an adult was taken in a grove south of Mission on July 14. Following
the finding of these specimens a thorough examination. was made of fruits
and berries growing in the Valley in -an effort to locate the host food,
out all inspections gave negative results.
The operation of 177 traps in 58 premises in Matanmoros resulted in
the taking of 23 ad-lts. Adults wore ta:en in four premises which had
not been previously reported as infested.
In-spection of f rait arriving in the market at ,Matamoros from points
in the interior of MTexico revealed infestations, in apples, oranges, 7
peaches, and Pears. A total of 45 larvae were taken from these fruits
during the mo.nth.


1TARCISSUS ?UI3 FLY (Merodon equestris Fab.)

The .7a'a-.-. ton inspection house reports an interesting discovery
of a larva in a small narcissus bulb (InTarcissus bulbocodiun conspicuous)
not more than 2 cm. in total length. Th1is larva was found in a shipment
arriving September 5 from London, Ragland. The occurrence of larvae
in such ,small bulbs is so unusual that photographs have been made of
the specimen.

INSECT CONDITIONS IN PORTO RICO DURING SEPTEMBER, 1931
M. D. Leonard
Insular Axperiment Station, Rio Piedras, Porto Rico

The sugarcane borer (Diatraea saccharalis Fab.) was worse, according
to S. C. McCall, local Manager of the United Porto Rican Sugar Company on
Vieques Island, on the 1931 crop, a total of about 3,500 acres, than it was
during the two p-orevious years. He stated that Japanese cane, usually sup-
posed to be somewhat less infested than other varieties, was the worst in-
fested of all during this past year.

Adults of Dyscinetus barbatus Fab. began appearing again at lights on
September 2 at Isabela (G.N.7.).

The yellow sugarcane aphid (Sinha flava Forbes) was reported on Septem-
ber 27 by S. C. McC.]Ilto have been absent on Vieques Island during the past
year as far as he could observe. Its absence or at least scarcity was
probably due to much more than normal rainfall on that Island.

The leafhopper Protalebra brasiliensis De Long known to be a minor
pest of sugarcane, has continued abundant throughout the month on Bidens pi-
losa at 7l Morro in San Juan.

The coffee stem-n borer (Psychonoctuam personalis Grote) was received
under date of September 29 in injured branches of coffee trees from Corozal
with the statement that considerable damage was being done to the trees by
the hollowed-out branches being broken off when they were bent down by the
pickers.

The coffee leaf miner (Leucoptera coffeella Staint.) was generally
distributed and quite abundant on a large coffee farm in the vicinity of
Jayuya, visited Se-otember 9-10. Apparently not much damage was being done,
however, to bearing trees.

The green scale (Coccus viridis Green) was observed September 9-10,
to be general, though not very abundant on a large coffee farm near Jayuya,
the younger leaves and shoots being more commonly infested as usual.

The coconut scale (As-idiotus destructor Sign.) was reported by Mendez,
Coconut Specialist at the Insular Station, as being not nearly so abundant
at Cabo Rojo during September as it was five or six months ago. As far as
could be observed, on September 26 practicallyy every coconut palm on Vieques
Island was more or less infested with the coconut scale, those towards the
eastern and drier end of the Island especially so, many palms having a
sickly and yellow appearance and in some cases even the fruits being almost
encyu,t ed- wil% the scal e s.

A bro'.n a-ohid was abundant on a nilber of tce tender shoots and young
leaves on a fairly large grame arbor at Puerto Real, Vieaues Islani, on
September 38.

Adults of Dia-mrcT,"en s- :i, lri L.. were less abundant than a short time
ago at Isabela, only one or tv.wo eg clusters bei:. .-,_ in several hours'

Au'gust. The seedlings were not more than 6 inches in hci.Ut and were
genc'r.-lly infested, about 5 -oer cent being killed before control measures
could be adopted.

The -oapaya fruit fly (To:otr.yonna curvicauda Serst.) Vas not found in
several fruits crIt -cn on a far- ne'ar Po:ce on S'?te-ber 9. The owner
stated that no i'J'-':'d fruits had been notic for several wee's, ;where-
as for-merly theiy : n heavily infested. As -reviously rep-orted, -.any
infested fruits had been destroyed and I suspect that this resulted in
grcatly reducing the infestation in this -olanting.

The scale Pseudo-arlratoria ostreata Ckll-. -was abundant on a nu:-ber of
gra-nefruit. trees near Ponce on Se-ote-uber 9.

The cassava shoot borer ('Lonchaea chalyrbea 'Jeid.) was received under
date of October 2 from the local ACric'iltural Agent at Bayamon who stated
that for some little ti-ne the insect had been very coe"rn'n in all the
cassava plantings in the district and had considerably reduced the yield.

- -" '.
By the eaw.L pxrt o- -..e ., On U osiL o1 e cotton had been harvested
around Isabela and during the month larvae of the pirn boll vw'orm (Pectino-
phora gossypiella Saund.) were abinidant in altcr-.ate hosts, especially in
the bolls of the -naga tree (Montezut-a seciossisiua)(G.7:.v.)."

Only one moth of the bean pod borer (Etiella zinckenella Treit.) was
taken during three nights' collecting, Scnte-iber 25-27, at Puerto Real,
Viequos Island.

The moths of the bean leaf folder (ITacoleia indicate Fab.) were fairly
comon at light Septe-ber 25-27 at Puerto Real, VieQues Island.

The ben aphid (Arhis ruinicis L.) was four-d on Sete-tbcr 8 in Con-
siderabole mnmbers on mamiy of the vines on the patch of polc li-no at the
Rio Piedras Station; in so-ne cases the long stems of the vines were cr)owVded
and there was a light to mn-vierate infestation on --'v lcves.








-544-


The bean lacebug (Corythucha gossynii Fab. ) was present in abundance
September 8 at the Station. The insect was observed in moderate numbers
on a number of castor bean plants in different parts of the Island, Septem-
ber 26 28.

A mealybug, Pseudococcus sn. was found September 8 generally though
lightly distributed throughout a fair-sized -natch of -Pole li-nas at the Sta-
tion on both leaves and stems.

Moths of the melon wor-. (Diaohania hyalinata L.). were fairly common
at light during three nights' collecting, September 25 27, at Puerto Real,
Vieques Island.

The small black squash bug (Pycnoderes incurvus Dist.) was fairly com-
mon at light during three nights' collecting,, Seotember 25- 27, at Puerto Real,
Vieques Island.

The Hawaiian beet webworm (Hyeenia fascialis Cramer) continued to be
abundant throughout the month on the veed Gonohraena disrersa at 31 Morro
in San Juan.

Grasshoppers did considerable injury to several large tom-nato plants
grown for ex-erimental purposes in the greenhouse at the Rio Piedras Station,
during the latter -art of the -onth. The injury was by young green nymphs.
Adults have not as yet been obtained.

Adults of the sweet-ootato weevil (Cylas formicarius Fab.) were not un-
com mon during three nights' collecting at light at Puerto Real, Vieques Is-
la-id, Semte-iber 25 27. Arturo Riolla:-o, the local Agricultural Agent,
stated that he had observed the insect as generally distributed and very in-
jurious since he had been on the Island fro-m September, 1930.

The corn ear worm (Heliothis obsoleta Fab.) infested practically every
ear of sweet corn at Isabela during the month (G.T.W.).
was received
A leaf beetle, Metachromna antennalis .'-eise/from the Aguirre Sugar Com-
pany was *. under date of Se-otember 4 for determination. The beetles
were said to be -oresent in enormous numbers and doing great damage to rose
bushes. Out of over 1,000 good-sized rose bushes over 400 had been killed,
the beetles first eating the flowers, next the leaves, and finally gnawing
off the bark of the woody -parts. The beetles first appeared in the spring
of 1929 and were -present the following year and this year from April into
September. It was stated that when disturbed the beetles drop readily. This
species was originally described from Porto Rico in 1885 by J. Weise and has
apparently not been reported outside of the Island, Here it has been re-
corded as rather badly attacking cotton at Quebradillas in June, 1922, and
was found between leaves and in spider nests on various plants on the beach
at Arecibo in May, 1923.






-645-


The chinch bug, Blissus leuconterus Say, w.as reported by A. J. Harvey
(who submitted specimens for determination) as causing severe damage in a
large -asture of molasses or "malojillo" ricls at Santurce on SePotember 12,
many large areas having been killed out. Mr. Harvey also stated that he
had recently observed similr injury in a large nasture of the same grass a
little east of Carolina.

A horn fly (Haematobia irr.tanti L.) was observed to be very a.L dint
on all the oxen in Vieaues Island on Se-otember 26-28, and S. C. McCall stated
that it had been worse this year th,-n usual. One bull was reported covered
with flies and in a gfre,,tly weakened condition if indeed not dying. The con-
siderably more than normal rainfall my be partially responsible but in
Porto Rico the -onest is ordinarily worse on the South Coast vchich has con-
si1crsbly less rainfall than the North Coast.

The bostrychid beetle Rhizo-ertha dominica Fab. (R. musilla Fab. A. J.
Mutchler det.,)accordin-7 to Dr. T?-T. A. Hoffman of the School of Trooical
Medicine in San Juan,has been a bad pest in the books in the library for
the past two years.





IITSECT CONDITIO1S IE. HAITI DJRIUJ JULY, 1931
Dr. J. G. Myers
Imperial Institute of Entomology
Trinidad, 3. 1I. I.

The s.';rc-ne butterfly (Calisto -oulchellus Lathy) was observed on
July 29 heavily infesting about three acres of sugarcane in a very damp
situation near Cape Haiti in Limbe Valley. Almost every leaf was more or
less eaten by the caterpillars.

The brown ant Soleno-Dsis geminata Fab. was observed on July 31 to have
killed about 20 per cenit of the young! gra-?efrulit trees (planted in January)
on 200 acres at Ca-oe Haiti by rinf4ing the bark at the base.

An undetermined mirid (reddish adults) was observed on July 29 injuring
a small patch of upland rice between Cape Haiti and Limbe. The bug was
abundant in spots, caus._.v- a yellowish or v.hitish mottlin of the leaves,
and the infested patches were considerably stunted. The s-me insect was
also present in two other localities far from rice, on the grass Fa!palun
distichum, which is -oro'-bly its natural food plant.

A black and spiny ncntatomid ba, was -oresent -and breeding on a S"mall
patch of upland rice between Cape Haiti and Limbo.
