INSECT PEST SUR VEY BULLET IN


Vol. 8 M'-rch 1,1920 Jo. 1


OUJTSTA'DING ENTOMOLOGICAL FEATURES IN THE u.I--D STATE' 7 FOR
JANUARY A:D F RUARY, 1928.

This number of the Survey Bulletin is the first of our eighth
volume. *7e wish to take occasion at this time to acknowledge the
very hearty cooperation that we are receiving from our collaborators.
The material has steadily increased and improved from year to year,
in quantity and quality, and -e 1"ish to solicit your continued contri-
butions to this work.

It is with considerable satisfaction thrt we note the organization
of a Survey to cover the Pacific Islands, prompted by the Hawaiian
Sugar Planters' Association and the Bishop Museum, Arrangenrnts are
being made by which the Insect Pest Survey will be kept in touch -"ith
such observations on economic insects as are made incident to this
Survey, The project is financed to the amount of $62,500 and is to
function for the next four years. Dr. J. Philpott Mumford vill have
charge of the field work,

What is probably the most serious development in the pirnk bollworm
situation that has occurred since the introduction of this insect into
the United States in 1917 is a new and very extensive outbreak in mid-
western Texas. As far as is known, a considerable portion of Ector,
Midland, Martin, Andrews, Glasscock, Dawson,and Ho"-ird Counties are
infested.

An unusually small number of sug-rcane borers entered hibernation
in 1927.

The abundance of bags of the bagworm on trees and plants readily
observable during the winterr months indicates that this insect -,-s es-
pecially prevalent during 1927 in south':,estorn Ohio and southern and
central Missouri.

The winter Hessian-fly survey in Kansas indicates that large. numbers
of this insect are still present in the fields. In the Middle Atlantic
States more flies have been observed than during the last fevr years, "-hile;
thrugu-iout the East-Central States moderate infestations are --aerally
reported.

The chinch bug is not reported as present in unusual numbers in
hibernation quarters ftom any part of the chinch-bug belt, and no early
spring reports of the green bug have been received.




-LABRARY
ST&TR PLANT BOART)

Throughout the Eastern States aphid esgs in general on deciduous
fruit trees are comparatively scarce, .....

Reports of very high mortality of the San Jose scale have been
received from the Eastern and Central States as fpr south as Georgia.

The Blastophap that played so important a role in the establishment
of the Smyrna fig industry of'California is now playing a new role in
that region as the vector of a disease known as fig endos-epsis.

Many larvae of the pepper weevil were found in February,indicating
a low winter mortality in southern Cadifornia.

During the late fall and early winter the vegetable weevil very
seriously damaged the turnip crop in perts of Mississippi and Albama.

GPRASSHOTPP7S (Acrididae)

Don C. Mote (February 20): Assistant County Agent La'-rence
of Klamath Falls reports about a thousand acres of grasshopoer
egg beds in that district and exi. cts a huge grasshopoer out-
break this season.

'HITE GRUBS (Phyllor,'igs sp.)

L. Hasemran (February 24): Recent lig-ings in a blue grass sol
orchard shov'ed grub worms to be unusually abundant and most of
them at a depth of less than 6 inches from the surface. To an
area of approximately 4 square feet eight grubs '"ere t--:en from
the first 6 inches of soil, all living, and to withinn the second
6 inches of soil.

C.C. Hill and H, D, Smith (January 26): Theat fields so'n in
the fall of 1927 in the east-centrl part of the State are heavily
infested ,ith the Hessian fly and considerable damage can be
looked for in this section. The southeastern and '-estern counties
are much more lightly infested.

C. C. Hill anl H, D. Sr.mith (January 26): The young h'.:-t is
heavily infested "-ith the Hessien fly in many of the "'heat-gro'"-ini
counties anl there are wors'i-cts of lamn :e from the fly in the
coi.iing year. Only light infestations "'ere found on the crstern
shore.

H. D. Smith (January 26): Wheat..fields sown in the fall of
1927 in Berkeley and Jeffersson-Counties are heavily infested
with the Hessian fly this year, Parasitism of the fall generation
of the fly in these'sections' is very low, which makes the out-
look probable for damaging infestations during"the coming
season.,

H, D. Smith (January 26): Many fields of young wheat were
found badly 'amaged by the Hessian fly in the counties of
Augusta, Clarke, Frederick, Pulaski, Rockbri. ge, Rockingham,
and Shenandoah. Other counties were less heavily infested.

H, D. Smith (January 26): Recent surveys of the counties of
C-uilford, Mecklenburg, and Durham showed that fields sbwmn
in fall wheat pere lightly infested rrith the Hessian fly with
no prospects of serious damage from this source for the
coming year.

W,. P. Flint (FebruaLry 21): Severe winter killing of -heat
has occurred in many of the 'late-sown fields in east-central
and southern Illinois. Early so-Tn fields in these'sectio4s
appear to be in better condition at the Present time, although
there are moderate infestations by the Hessian fly in most
of these fields. ,

L. Haseman (February 24): No recent observations have been
made on the -intering conditions of the Hessian fly but in
seeding plats for Hessian fly studies at Columbia it was
found from inspection of plant-s during December that a fair
infestation of the fly seems to be a.in developing in'this
area.

J. W',7. Li:cColloch (February 23): The Hessian fly promises *to be
a big problem again this year. Surveys made during the fall
and early -inter showed a rather heavy infestation throughout
central Kansas, extending from Sumner County to Clark Connty
on the south, and reaching northward almost to the Nebraska
line. Material whichh ,has been collected in the field shows
that the -inter mortality has been light, and -,ith favorable
conditions this insectshouli cause considerable trouble in
May and June,

CHITCH BUG (Blissus leucooterus Say)

J, '7, >cColloch (February 23): The chinch-bug outbreak which
has been under way for several years appears to be about
over. Excessive rainfall last summer -as very detrimental
to this insect, anvl as a result the number of bugs going into
hibernation lJst fall 's compzretively light. There has also
been a rather heavy -.ortality of the bugs in hibernation, 'ue
to several abrupt -roqs in temperature following periods of
wuarm -eather.

C. B. Dibble (February 20): It may be of interest to note
that another lot of Microbracon_ chI Ashm,, a native
parasite, '"as bred from corn-borer material collected by
myself at Honroe during the sumrmer of 1927. The determination
of this species r7as rade by Yr. A. B. Gahan of the United
States Bureau of Eatomnology.
It is also of interest to note that the fungus Sporotrichum
globuliferum, as determined by Frof, Pettit, -as likewise
obtained from the experimental plots at the Michisan State
Corn-Borer Station near Monroe,

EUROTPEAN RED MiITE (Paratetranychus pilosus Con. & Tanz. )

E, .,7. Mendenhall (February 23): I find the eggs of the European
red mite on apple trees in the southwestern part of the State
quite bad, especially where trees are neglected and not sprayed.

SAN JOSE SCALE (Aspidiotus perniciosus Comst.)

W, S. Abbott (February 16): Appears to be increasing in this
vicinity (Vienna).

E. Lee 'lorsham (February 10): It may be of interest to you to
know that the cold weather we had in January w.as responsible
for reducing the San Jose scale in the commercial orchards in
middle and northern Georgia from 75 to 95 per cent. In the
Cornelia district ,Te were unable to find enough scale in any
of the orchards for our experimental .work.

E. 7 Mendenhall (February 23): I find the farm orchards where
there is not much care given badly infested with the San Jose
scale. Where periodical sprayings are carried on the scale is
held pretty well in check.

S. C. Chandler (February 21): Examination of unsprayed scale
on January 20 showed about 60 per cent of the scale in the
overwintering stage to be dead. Some injury to peach trees has
resulted from fall applications of dormant spray from both lime
sulphur and oil, the injury by the oil being slightly more
severe than that caused by lime sulphur.

L. Haseman (February 24): From recent counts made in connection
with some oil-spray tests at Columbia, Mo., it has been found
that practically 99 per cent of the scales have been killed by
winter conditions combined ,7ith parasitism. The records from
untreated trees show, a little better than 1 per cent living
scale.
APPLE

700LLY APPLE APHID (Eriosoma lanigerum Hausm. )

L. Haseman (February 24): In southern Missouri during the past
season the .oolly aphis was unusually abundant and from recent
inspection surveys in the Marionville district it is found that
overwvintering signs of the aphis ahow promise of a heavy in-
festation this coming year.


CODLING MOTH (Carpoca sa pomonella L.)


7, P, Flint (February 12): Examinations of overwintering larvae
made by members of the Survey staff in southern, eastern, and
westcentral Illinois show that in southern Illinois approximately
20 per cent of the larvae have died during hibernation, while in

TILE HORFED PEIC'UJS (Prionus imbricornis L.)


Mississiopi


E. W, Harned (February 15): On January 14, Inspector R, B, Deen
sent in t "o large larvae that '-ere taken from peach trees on
the property of James A, Coleman, Tupelo. One of these larvae
is still alive in the insectary. The 6ther -pecimen '"-as sent to
Washington and identified by Dr, A, G. Boving as Prionis
imbricornis I,. The owner of this orchard wrote on January 24,
as follow's:
"These borers were gotten out of adjoining trees that were
25 feet apart. Both of th-se trees vwere in a very rich sandy
loam at the foot of the hill in my orchard. I find most of my
borers in this part of the orchard and very few in the '-.avy
clay near the top of the hill. These -'orms came out of es'-cially
fine trees -hich bore fine crops in 1923, but sho,&el si -s then
of dying. I pruned them very close, but they sho'"ed further signs
of decay last season. About half of the trees were still alive
when I had them -ug up, an:1 I feel sure that the '"orms killed the
trees. Iy attention 7as attracted to them because of their lar.'e
size, but more especially instead of boring bet-een the hrk
and the 77ood, you will notice from the specimen of the root sent
you they bored directly into the "o. These trees ."ere with paradichlorob,.Taene in October,1936, and October, 1927, but
evidently this hal no effect on these borers."t

boLthly News Letter Los An,,:les Coanty Horticult'r-Ul Comrrission
Volume 10, iTo.l, (January 15): A survey of k'-'o-n planting -s of
caprifigs in Los An-elr: County has recently been completed,
accordin.- to K. L. Tolff, Deputy Horticultural Commissioner in






























California


Charge of the Survy in that area. The "'ork was carried out as
part of a State-wide program of the State Department of
Agriculture to vipe out the disease known as fig endosppsis.
According to University of California authorities, this disease
is transmitted to the Smyrna type figs by the Blastophaga
'rasp, necessary to the proper nollimization of this species of
fig. Under the plan of operation all of the overwintering
or mamme crop figs are to be picked adr1 forwarded by the growers
to a central .point of sterilization before February 15,1928. The
emerged wasps will be returned to the owners in vials to be
released to the profichi crop. This latter crop can then be
distributed in the commercial orchards in the usual manner.
Thile the survey showed a very limited number of caprifig
trees in the county, their listing and subsequent proper .handling
is of the utmost importance-to the success of the disease-control
campa i gn.

WALNUT

CODLING MOTH (Carrocapsa pomonella L,)

Monthly News Letter Los Angelis County Horticultural Commission
Volume 10, No. 2 (Febr'ary 15): In several new areas of Los
Angeles County walnut growers found it necessary to treat for
the codling-moth for the first time last season. According to
figures compiled by K. L. '"oiff, Deputy Horticultural Commissioner
of I Los Angeles County, gro-ers in these new areas sprayed
724 acres and dusted 89 acres for this pest during 1927. Mr,
Volff further states that control, results were comparable to the
degree of control obtained in the older infested areas of the
county during previous years. Tray counts on iirdex orchards
showed the average treated property to have an infestation of
2.8 per cent, while untreated orchards in the same area averaged
7.5 per cent. .

Monthly Ne-s Letter Los Angeles County Horticultural Commission
Volume 10, No.2 (February 15): Citrus Pphi s'are getting an
early start in many parts of the county according to reports
of Los Angeles County district horticultural inspectors, and
r'ill bear careful watching. They are damaging new growth by
their attack almost as soon as the buds break. The attack at present
seems to be confined to 'the south and east or warmer sides of the
trees, New fruit wood in many cases is either killed in the
initial stage or so weakened that it can not support the normal
bloom. Failure to set a crop may often be directly traced to
neglect in instituting timely control 'measures aminst this
pest.

SPRtBAS APHID (Aphis spiraecola Patch)

J, R, 7atson (February 23): Among the outstrndin, entomological
conditions in Florida this year is the scarcity of the citrus
aphid. It does not appc:r now that they can possibly get
abundant enough to do much barm to the first flush of -.ro7th
and to the bloom* This happy condition of affairs is due
entirely to the drought and freezes of the past winter whichh
either inhibited all new gro7rth on citrus or froze it so that
the aphids starved to death. This, of course, refers to Aphis
spiraecola.

*WHITE FLIES (AlcAiLd.ae)

J, R. Watson (February 23): Dialeurodes citri and D.cittifolii
have been somewhat more abundant than usual because of the
drought which prevented the proper development of the
entomogenous fungi. The rainfall for Florida during 1927
averaged about one-third less than-normal an'1 the result Tas
a heavy increase of these insects which are usually controlled
by the entomogenous fungi.

CITRUS 7THITB.E (Dialeurodes citri Ashm.)

Monthly News Letter Los Angeles County Horticultural Copmmission,
Volume 10, ITo. 1 (January 15): The citrus white fly is one
of the insect pests against vhich California is zealously guard-
ing her citrus orchard. It is for that reason that a local
well known nurseryn.an should be commEnidc for his cooperation
in taking up with the County Horticultural Commissioner the

immediately cancelled all negotiations for the plants.

W, E. Hinds (Fcbruary 25): The citrus b-hitefly is hibernating
on its usual host plants but the cold of early January resulted
in rather complete defoliation of citrus an! reduction of
foliage on privets also ,7hi.h -ill result in reucinF the
initial infestation by this pest.

PEPPER

PEPPER vIEVIL (Aithonomus eugenii Cano)


California


J. C. Elmore (February 21): At present the pepper weevil is known
to occur in Ventura (first found here in January, 1928), Los ,ngeles,
Orange, San Diego, Riverside, and San Bernardino Counties. As indi-
cated, Ventura County is a new locality and a very important one
because pepper growing has become a very important crop there. The
pepper crop in Orange and Los _Angeles Counties was damaged about 25
per cent on the average with the losses running as high as 50 per
cent in some places. The lesser damage compared to the previous sea-
son was due to the late spring and control operations. During the
present winter immature states of the weevil have been found in aban-
doned fields to date (February 20). This condition is unusual as it
is not common to find larvae and pupae so late in the season. Basing
our estimate on previous knowledge, the pepper weevil will probably
be among the front ranks as an outstanding insect pest this coming
season. Many abandoned pepper fields have remained standing where
until recently, it has been possible to collect hundreds of adult
weevils for hibernation studies. There appears to be no hibernation
so far this winter. This point is very interesting in view of the
very definite hibernation period with the cotton boll weevil.

the months of November and December. I made an inspection of an old
turnip field \.nd found the damage to be caused by the Australian
tomato weevil or turnip weevil. I found larvae of this insect just
below the surface of the ground. They were dead owing to the recent
freeze. M1r. Leatherberry stated that about 90 per cent of the tur-
Rip crop in that section was killed or damaged by this insect. They

J. R. 7atson (February 23): In late Decemiber and early January tur-

PIINK BOLL WOE.. (Pectinophora gossypiella Saund.)

Official Record, Vol. 7, No. 6, (February 8): A new, and very exten-
sive outbreak of the pink boll worm has developed in western Texas.
This new invasion has been'found to cover a considerable portion of
Ector, Midland, and .,arten Counties in the western part of the Texas
cotton belt. This is probably the most serious situation in pink
boll worm work that has developed since 1917.

BOLL 'EEVIL (Anthonomus granndis doh.

'. E. Hinds (February 25) -,'inter minimum temperatures in Louisiana
have not been low enough to a.ccrmplish any unusual destruction of
boll weevils in hibernation. At the time of minimum cold it was also
dry, and this combination is less effective than the same cold if
i:i,'ediately following heavy r..ins. Boll weevils have not yet begun
to emer.e from our hibernation cases, but we anticipate at least
an average abundance of weevils to start the initial att-.ck on cotton

be much lighter this spring tharn-a year ago. During February an
excess of rainfall and frequent cold spells have held back the early
growth of cane, but sprouting of cane in the fields has been unusu-
ally abundant for this time of year because of the greater vigor of
the new varieties which are now being planted generally.
