OUTSTA!TDIIIG EITOI.10LOGICAL FEATURES IN THE UNITED ST-.TLS FC'2R OCTOBER, 1929.
Unusual numbers of grasshoppers appeared late in the season in the
western Great Plains States and the northern Rocky ioantain region, and
considerable apprehension is felt as to the outlook for next year.
The Hessian fly se-oms to be decidedly more numerous in southern Io-a
and Nebraska, Illinois, and .Missouri than for the past few years, 'Tebraska
reports that a new outbreak is starttng in the southeastern part of that
State, and a general outbreak is reported from Missouri.
The fall armyworm continues to be reported as destructive in the
Southern States. It destroyed many acres of winter s-oinach in the -Torfolk
district of Virginia and it completely destroyed new;ly-seeded alfalfa at
one locality in :.iississippi.
The clover seed midge has been seriously reducing seed yields in
many districts in southern Idaho, and the clover head caterpillar is doing
considerable damage to the seed crop in parts of Nebraska.
The pear psylla has been reported for the first time as a serious pest
in southwestern Illinois.
Very considerable injury by the oriental fruit moth is reported from
the Miiddle Atlantic, Southeastern, and East Central States from :I-' Jersey
to Georgia, and from Michigan to Thnnessee.
The plum curculio is going into hibernation in phenomenally large num-
bers in Georgia and Tennessee.
The numbers of the --.alnut husk fly have been vwrv materially reduced in
the Chino-Pomona district in California by the practice of control measures.
No field infestation of the Mediterranean fruit fly was found in Florida
or elsewhere in the United States during the past month, nor were any adults
of this insect collected in traps.
The citrus whitefly sm-ms to be quite generally troublesome in the
gulf section from Florida to Mississippi.
The southern green stink bu- has ruined the winter tru'-ck crops in
several localities in the Southeast.-rn State.
The first eggs of the vegetable reevil for this season were obs:.rv.d
about October 1, in the vicinity of Gulfjport, 1,[iss. .This insect is no7
known to occur in 85 counties in four of the Gulf States.
The pepper .weevil has very seriously affected the crop of .czr5 in
parts of '._ Mexico, Texas, and California. This insect has also serio-isly
injured e-,oplant in southern California. This was of tnhe Jrpanece vari.ty.
The common eggplant did not se.m to be infested.
Additional reports of the finding of the ":.xican bean beetle continued
to be received during Sept-tuber and October. The range of this insect no-
extends well up into Michigan, Ns^WYork, and ::assachusetts. The spread to
the south and west has been negligible.
The southern pine beetle is appearing in rather decidedly outbreak
numbers in several localities in western North Carolina.
An infestation of the pink boll -orm has ..-c; recently disco-.cr
near PKioenix, Ariz.
T7. A. Price (October 18): Grasshoppers are moderately abun-
dant on clover and alfalfa, principally in th2 northern and
central parts of the State.
iMi. H. Swenk (October 1): Grasshoppers were present in unu-
sual numbers over the whole State in September and continued
to damage alfalfa fields and vegetable and flower gardens
throu'hCout the greater part of the month. Present indications
are that there will be increased injury in 1930.
L. Haseman (October 26): vielanoplus fumur-rubrum DUG. is
very abundant at Columbia.
C. .,akeland (October 20): Alfalfa seed growers of east rn
Idaho report fairly heavy infestations this year and are con-
cerned about losses next year. de recently examined some
of the heaviest infested localities and were unable to find
egg masses in abundance. The species most abundant ,ere
.c.lanoplus bivittatus Say, M. femur-rubrum DeG., Dissosteira
carolina L., with a few individuals of Aulocara elliotti Thorn.
and Arohia pseudonictana Thorn.
.iJiL ?.'.IS (Phylloohaga spp.)
7. Chambers (October 19): ; rite ;rubs are very abundant
on nursery stock (especially evergreen scdlings in beds) in
Stv -r sections of tht State. Heavy beetle flights occurred
in June. The situation has been developing very rapidly during
the p-ast fev, -,eeks and rhile ire did not anticipate any injury
whatever from white grubs, our nurserymen throughout the State
are reporting that owing to the prolonged growing season the
grubs are already doing serious injury to seed beds and have
not yet started down belo7 the frost line.
C 2REAL A D F C R GE C ROP I N SE C T S
_-j.SAL- FLY (Ph'to :.h3z destructor Say)
T. 'H. Parks (October 24): Very fe-w _n -7ere laid on the
ne,7 crop except in Butler County '"here the infestation in the
crop of 1929 was high. Daily counts of eggs laid on 100 plants
in Butler County sho"'ed the maximum egg laying to be reached
September 28 and to be over by October 13. .heat sowed after
the fly-free date (October 2) 'ill be reasonably free from in-
festation. Seventy per cent of the (; .s were laid from Septem-
ber 28 to October 1 inclusive. '
%. xW w
J. H. Bigger (October): There is a v.ry severe infestation
in early seedlng.-. I visited one field of 17 acres destrcyed
C. J. Drake (October 19): :od3rately abundant in the south-
ernmost tier of counties.
M. H. Sv.enk (October 1): There is decidedly more evidence
of the Hessian fly in southeastern N-braska tids fall than
there has been for the past three falls. The last cycle of
damage in this region 7:as in tne winter heat crop of 1921-22,
and 1925-26, reaching its crust in that of 1S2-23. ::o comer-
cial damage occurred in the winter ..at crops of 1926-27, 27-
28 or 1928-29. Since the 1929 harvest, however, scattered and
loccl infestations (mostly light), of the stubble have becn re-
ported and there has been a fall brood of fair strn-.gth active
during the month of September. The infestations occur from
Cass, Otoe, :emaha, and Richardson Counties to Jefferson, Lan-
caster, Sewvard, and Hall Counties. It se ms likely that a nev
cycle of fly damage is starting this fall. ",here there as
evidence of fhe presence of the Hessian fly at harvest or
7'here puparia were common in the stubble in July and Au-ust,
local delayed sowing.was advised this fall. It seems -robable
that increased damage may make necessary a general ca7:rai'n cf
delayed sowing in southeastern Pebraska.in 1927. Already in
Richardson County the ea-ly sov7n wheat is showing'"ly daLg .
L. Haseman (October): There is a real outbreak covering
much of the State this fall, but the extensive campaign urging
the dec-laying of seeding has, I hope, greatly reduced the dam-
age from the pest.
A.-Y.7CR.I (Cirohis uniouncta Ha--.)
0. L. Barnes (October 23): Considerable damage 'as done to
small grains near iEagar. One field of several acres -as com-
pletely stripped of foliage and the -orms were destroying the
maturing heads rapidly. T.-. date ."as August 27. Larv.a: of
this species .7ere found scarce to moderately abundant at sev-
eral places in Navajo County, but in no case in such numbers
as at Lagar in Apache County. On September 21, s-:,cimens "ere
received from C. C. Leuker, county :aricultural a-ent of
Coconino County, "7ith a note that severe injury to cabuege and
oats had been done at the county farm near Flagstaff.
CCOi ER C'iX (Heliothis obsoleta Fab.)
.. Britton (Cctober 24): iore abundant throughout the
State than usual.
A. G. Rucg4las and assistants (October): Reportcd as very
abundant in Ivowtvr, Renville, Nobles, and Henn-oin Counties.
COLORADO CORN ROOT *'ORM (Diabrotica virgifera'Lec.)
,... H. S'enk (October 1): During the first half of Sept cmb r
additional reports were r,.c.ivcd of injury to corn in south-
,' western Nebraska.
SOY `, ,
VLLT77T BEL:' CATERPILLR (Anticarsia 7-camatilis Ibn.)
R. :. Har:-.cd and assistants (October): VWry abundant on
soy beans in Yazoo County, many fields being entirely stripped.
Also found in one alfalfa field. i.oerately abundant at Lamar
and Holly STrings stripping the foliage of soy beans.
SORG_'L ','.,"OR (Celama sorehiella Ril.y)
L. Haseman (October 26): For the past tv7o months the sor-
ghum storms have bceen complained of by growers of grain sor-
ghums in the southern counties of the State. In some sections
the infestation has been. v.ry serious.
C-.IJCE: :-U3 (Blissus leucoiterus Say)
E. Britton (October 1): Adults and n'.:hs havekilled
the grass in a small patch of la7n in Hartford. Similar oc-
casional injury has been observed in former seasons.
?ALL A:Y .;PCRM (Laphygma frugiperda S. & A.)
P. J. Chapman (October 2): This worm .as very injurious to
the young spinach crop in the area of Norfolk. ILany acres
were so badly damaged that they were oplo red up and resovn.
G. I. "orthington (October 19): Stripped 200 acres of ne'7
alfalfa. This "'ill probably prove to be a total loss as the
alfalfa. ras not securely rooted and was not able to withstand d
ATM PIANr HOARD
ALFALFA THRIPS (Frankliniella occidentalis Pcrg.)
G. F. Knowlton (October 28): This thrips has been abundant
on alfalfa at Greenwood during the past season according to a
report from Mr. Kay Sakimura.
CLOVER SEED l.ID2E (Dasyneura l--um.iniccla Lint.)
C. ?akeland (October 20): Seriously reducing the s.ed yield
on red clover in many districts in southern Idaho.
CLOVER HEAD CATERPILLAR(Ie reaia interstinctana Clkm.)
M. H. Swenk (Oltoer i): Considerable damage was done to
the red clove: s-ed crop in ,"ashington, Dodge, arnd Saunders
Counties during the early part of September.
F R U I T I I SE C T S
APPLE GRAIN APHID (Phopalosiphum prunifoliae Fitch)
T. H. Parks (October 13): grantsns are appearing on apple
trees and giving birth to oviparous forms. They are not v.ry
APPLE APHID (Aphis pomi DeG.)
-7. A. Price (October 18): Reported from Honderson, Jeffer-
son, and Fayette Counties.
R. H. Pettit (October ,.): Very abundnt at Fernville.
CODLI1TC MiOTH (Carpoca'sa potonella L.)
S. C. Chandler (October 1): Infestation by the late second
brood and the third brood of the codling moth bcnc more seri-
ous than w:a3 anticipated in the southern half of the State.
L. Haseman (October 19): moderately to very abundant; very
serious in the Ozarks, but in central and northern 14issouri
not so bad.
APPL ,CRU. .PLER C(riiola indigenella -ell.)
L. Has...an (October 26): Very abundant, particularly on
young fruit trees and on the native haws in central Missouri.
A LUCOSMID MOTH (Enarmonia pyjricolana Murtd-ldt)
0. I. Snapp (October-18): Infestation rather heavy in ter-
minal buds of young apple trees at Albany.
SAN JOSE SCALE (Aspidiotus perniciosus Comst.)
T. L. Guyton (October 25): Reported as being on the increase
in the Cumberland Valley orchards. This report camc to me
through the head of the market. inspection service on fruit.
0. I. Snapp (October 21): The San Jose scale has incr:- ,d
rapidly since the middle of August. Orders already placed
-ith insecticide manufacturers indicate the use of more
liquid lime-sulphur in the South this ,winter than last.
J. oi'7atson (October 20): Mioderately abundant; heavily in-
fested VitH 'a fungus.
PEAR PSYLLA (Psyllia pyricola Foerst.)
S. C. Chandler (October). i,.:. pear psylla has become serious
this year in a large pear-growing area centered at Alma, about
60 miles cast of St. Louis. Aide from the characteristic
defoliation, several gr-'ers reported that one-third of their
crop was too small to ship this season whereass usually only
about 10 per cent is undersized. This is the first time that
the pear psylla has been reported as serious in Illinois.
TAIILShD PLT 3BU3 (LyLus oratansis L.)
E. J. Newcomer (October 21): This insect has been damaging
mature pears at Yakima and ?Tenatchee by sucking juice, and
has been coming into gardens and attacking roses, chrysanthe-
mums, etc., recently.
OI.r FRlT EOTH (La'r.ia molsta Busck)
O^I-.nL R-IT 1.OTH =L^^rsamLesta Busck)
H. 7. Allen (September 26): Counts of 2,300 p7cc0 C,
varieties Krmmnel and Iron M.ountain, in Burlington County,
between S.- t:7mber 19 and 25, indicate a total infestation of
51 per cent, of which 20 per cent was visible and 30 per cent
T.'L. .Guyton (Octboer 25): The oriental fruit moth at
Harrisburg by actual count on some Carman check trees runs
49 per cent -ormy fruit. A check on Elberta ran practically
the same as did those on Iron mountain n aind Salay. I rather
suspect that all untreated trees in the vicinity of Harrisbur,
would run about this rate of infestation. All of the fruits
on these tress were cut open and examined. In examining
these patches it was concluded that about one-half of the
77ormy fruit showed external evidence enough to cause the ordi-
nary grader to throw it out.
Georgia 0. I. Snapp (October 11): The infestation is vary heavy at
Summerville. Apples are affording a host for the late broods.
Ohio T. H. Parks (October 24): T":ig injury is prominent on back-
yard trees in cities and farms. It is also evident in twis
of commercial orchards in northern Ohio where the peaches did
not bear owing to winter killing. The Elberta crop in southern
and central Ohio had a much lower infestation than in 1926
while late maturing peaches had almost no injury at Columbus
compared to a very heavy infestation and partial crop loss in
1928. Quinces are very wormy again this year. The insect
has not become a serious pest of apples in Ohio.
Kentucky .,. A. Price (October 18): Very abundant in the northern and
i-stern parts of the State. A $17,000 loss was caused by it
in Jafferson County this year. in one orchard.
Mlichigan R. H. Pettit (October 18): Moderately abundant from Anne
Arbor to the Ohio border on the eastern side ff the State.
Tennessee 0. I. Snaop (September 28): The infestation is heavier
around Harriman than it has been before. Some young orchards
show considerable twig damage by earlier generations. From
15 to 20 per cent of the fruits from some peach orchards in
this district ware infested.
F.#CH BORER (Aeteria exitiosa Say)
Georgia 0. I. Snapp (October 18): In taking results of control ex-
periments in the Fort Valley section, we find the infestation
to be much heavier than normally. (October 21): .e are
still finding a few pupae. Therefore, there is a possibility
of late oviposition this year.
C, H. Alden and M. S. YComans (October 19): moderately
aburndznt at Cornelia.
Texas F. L. Thomas (October 2.): Very abundant at ^acoodoches;
lost about 75 trees last summer and no- lookin.V for control
PEACH T.IG3 B,',RD (Anarsia lineateUlla Zell.)
Arizona 0. L. Barnes (October 23): 7coorted as abundant at St.
Johns October 1.
PLUM CURCULIO (Conotrachelus nenuphar Hbst.)
0. I. Snapp (October 21): Practically all adults h.v_ left
orchards for hibernation quarters. The population in hiberna-
tion is unusually large in the middle Georrgia peach belt.
0. I. Snapp (September 28): The infestation this year -as
the heaviest ever experienced by Tennessee peach growers. The
fruit in some orchards showed a 35 per cent infestation. An
organization has been perfected to wage a campaign of curculio
suppression throughout the district of Kingston.
U'BLE FLOER BEETLE (Euphoria inda L.)
MI. H. Swenk (October 1): In Saunders County during the sec-
ond week in September the brown fruit chafer was reported as
doing extensive damage to peaches by eating holes in them.
GRAPE BERRY :.OTH (Polychrosis viteana Clem.)
T. H. Parks (October 24): Very abundant in the Lake area
of Cuyahuga and Lorain Counties.
M. H. Swenk (October 1): A Pawnee County correspondent
sent samples of grapes badly injured during the first week in
GR1pPE CURCULIO (Craponius inacqualis Say)
E. _i. Mendenhall (October 3): Indications are that the
grape curculio is quite bad in Columbus-and vicinity.
GRAPE LEAFHOPPER (Erythroneura comes Say)
M. H. Swenk (October 1): Injury to grapes and woodbine fo-
liage, especially the latter, 7as reported during September.
PACIFIC RED Sr-IDEP (Tetranychus pacificus MicG.)
E. A. McGregor (October 28):, This mite, possibly the 'orst
pest of deciduous fruit crops in central California, exp,,rinced
a remarkable decimation in numbers late this summer. During
recent years this mite has become increasingly threatening in
vineyards, and it was severely attacking grape vines as late
as September 1. However, at about that time, Scolothrips
sexmaculatus Perg. underwent such an increase in numbers that
it succe-dcd in almost completely exterminating the mitue ti
a very short time.
-TALJT FTU(: FLY (a:%oletis jul-dnli. Cr-.:s.)
Monthly News Letter, Los Areles County :.-ricultural Con.,
Vol. 11 No 10, October 15: R-sults of control -ork- conducted
in the Chino-pomona district against the alr.ut -uc fly ar
very satisfactory. In several treated orchards Ahich last
year showed 90 per cent of the nuts to be infested, it -a- al-
most impossible to find a single infested nut this season. In
contrast, untreated orchards showed a very heavy infestation.
I\EDITER.-L.: FRUIT FLY (Ceratitis canitata \Ti-i)
Plant ,uarantine and Control Administration (:'-,vember i):
No : -diterranean fruit fly '.ras found in Florida during October.
Monthly 1.-s Letter, Los Angeles County Agricultural Comm.,
Vol. 11, .To. 10, October 15: A recent survey of Catalina Is-
land has failed to show any .-.diterranean fruit fly to be
present. The inspection of the Island was carried out as part
of the State-wide survey.
CITROPHILUS :.L.LYBUG (Pseudococcus gahani Green)
Ivionthly News Letter, Los An-eles County Agricultural Comm.,
Vol. 11, :;o. 10, October 15: Since July 1 the County Inscctary
has distributed 172,000 of the new parasites of the citro:hilus
mealybug which -were recently brought into California from
Australia by the University of California through the citrus
Experiment Station at Riverside. These parasites are known as
Coccoohagnus Purrio-yi Ci-...,. Liberations have been confined
to placing. small colonies on as .Tany infest-d properties and'i
over as ride an area as possible for establishment purposes
*Previ'ous liberations indicate that the nc- parasite is be-
coming 7ell establish.-d and that, if it does not prove a con-
trolling factor al'one,it 7ill undoubtedly be an invaluable
assistant factor in keeping; this serious citrus pest under
control. At pres-ent the .rnalybug situation in the field is
very satisfactory with all infestations at an extremely lo-

Mississippi coast. It "'as-observdd first at Gulfport ani
Long Beach by thc writer in :Uov_:b.cr, 1926, and has czr-ad
rapidly since. It is now so numerous in some fields that
three plantings of such crops as cabbage, spinach, etc., '..!
had to be made owing to its burrowing in the rows just as the
plants came up.
POTATO -:'D TOIriTO

per weevil infestations were found in garden plantinPs of C..ili
pe'-pr ero.urs at San Antonio, Tex, At iotect, Tex., gro'%rs
reported damage so heavy that pepper fields ,::ere plowed up
earlier in the season, but the infestations o'ero not verified
by the writer. The insect is rell distributed near Venton,
Tex. (October 1): P epper weevil damage has been v.ry he&vy
in Ventura County, near Camarill, Calif. TLo fields ,Tore a
total loss by September 30. Practically all pepper fields in
the county are affected, damage ranging from a trace to almost
100 per cent. (October 16): The pepper '-,eevil has b-cn
discovered infesting eggplant in Orange County, California.
Larvae and eggs wviere found both in the buds and in the pods.
A Japanese variety is more suaceptible although larvae and
eggs were found in the buds and in the pods of the common vari-
ety. In two localities the Ja:--nEsc eggplant was very heavily
infested, but it was growing in the edge of heavily infested

on cabbage and collards a,-i have done considerable! dLe--J
throughout the month of October near Charleston. The plants
are being attacked both in the plant bzd and after being tran-i-
planted to the field. The :;orst injury was suffered -eriw-
the early part of the month, at which time the ~eath-r 7as very
unfavorable for plant growth, as. well as for efficient use of
control measures. Insect enemies. lady"-ird beetles, and. 'nhe
