INSECT PEST SURVEY BULLETIN


Vol. 10 September 1, 1930 No. 7


0UTsT. 2DmCG NET0CQ0LO0ICAL FCATLJES IN THE UTITSD STATE Au:T 1930


The serious grasshopper conditions reported in the last number of
the Bulletin continued during A11 ast, and particularly serious outbreaks
occurred in Idaho and northern Utah.

The pale westernn cutworm 7as reported as locally serious in Utah,
and the Bertha army7orm ras reported in outbreak numbers in the north-
eastern corner of -'orth Dakota during August.

The periodical outbreak of the white-lined sphinx reported from
I'evada in the last number of the Surve., Bulletin extended westward into
the Lake Tahoe region of California.

The dry-feather conditions of July extended through August and,
as vas to be expected, damage by the red spider continued throughout
the month.

In this number of the Survey Bulletin is a surrmary of the Hessian
fly survey of TNeT York State. The infestation as a whole is light,
averaging for the State 3.7 per cent. In southeastern iTbraska about
80 per cent of the puparia were dead by the last of July, largely
as a result of the hot, dry -.-eather.

The fall arxrnvorm continued its depredations during August through-
out the Gulf Region.

Very sever. damage by several species of corn root worms is re-
ported from south-.stern Hebraska; Diabrotica virgifera Lec. was the
most destructive species. A species heretofore of practically no economic
importance, D. filicornis or...- also seriously numerous.
The velvetbean caterpillar i., again apoe:'ring in part of Louisiana,
although not so numerously as in 1929.

On the 'whole, the c'2llin- moth seems to have been stimulate by the
unusually high s--.m-cr temperatures, arn. severe late injry, is r- crtz-
from- the entire drought area.

The oriental fruit moth is apparently not unusually abundant thr:gh--
out the ew Ln,:l:.nd and Middle Atlantic States; in fact tw.ig infestation
has been lighter than usual over much of this territory. Ti-.is condition
extends southward to Georgia &/ii -.estward to Indiana.

The plum curculio sCems to be unusually atc:iJnt throughout the
Northern States and at a very low ecb in the South,

The citrus whitefly and the citrus rust mite have been :ore trouble-
some than uZua_ in Florida. This is believed to be due to the dry -eat:=;-r
inhibiting the developm-nt of entomogencus fungi,

Blister beetles are generally prevalent and destructive throu-hA:t
the East-central and :ortCh-ce.-..ral States.

The asparagus beetle is dI.finitely recorded for thw first time
from southern California. Thec pest has been more or less serious throu':-
out central California for a nuIber of years.

In Massachusetts the :'-xican bean beetle has been found to be 7ell
distributed over the Connecticut Valley region of Hampden County ani north-
ward into Hampshire County. The pest has also been found in a fe7 in-
stances in _rar:lin County. In tIhe older infested States in the drv.:t
area the insect was r,_duc,:: to a negligible factor by the high t=r-.-.rrtures.

Tobacco horn-?orms are very decidedly less abDuni:Dnt thinr. usual in the
Tennessee tobacco-growin districts.

The saddled prominent, Heterocar.nr:. uttivitta Jalk., is a:-erinz
in outbreak numbers in the 7ie-- r.an.d Stetes .-here it is defoiiat:-.
large areas of beech and maple.

The gipsy moth i3 at a lo-: ebb of 'bundancc but th'i brovn-tail o:oth
is showing a decidedly um,,ord trend i. the 1e Il;and States.

A repetition of the outbreak of thIe re":-.striped zaple wor .-hich
occurred in 1917 and 1918 is occurring in parts of "'-C3achusetts :.n
Connecticut.

GRACS,:PFLRS (Acrididae)

T. H. Parks (August 25): Complaints about grasshopper
damage were received from Clinton County, in the heart of the
drought area. Damage to soy beans occurred after the hoppers
had left meadows and pasture fields, where the grass was
destroyed by heat and drought.

H. ;. Riddle (August 14): Infestations have been noted
in Dunn, Divide, Pembina, icLean, and particularly in .alsh
and Grand Forks Counties.

H. E. Jaques (August 20): Grasshoppers are very abundant
in the western half of the State and moderately abundant
in many other counties.

F. F. 1-msler (August 18): Romalea microptera Beauv. is
abundant at Gulfport.

::. H. Swenk (July 15-August 15): Grasshoppers (:.:cl.:,nlu:
differentialis Thos.)developed considerable abunC'ance and
destructiveness in Nebraska during the period here covered.
3o, d County suffered a particularly heavy infestation, with
considerable injury in the alfalfa and grain fields. Other
centers, of severe infestation were southern Brown County,
Platte and Polk Counties, and southern Lancaster, Otoe, and
Johnson Counties. S -rious damage was done to apple orchards
in Otoe and Cuming Counties by the grasshoppers stripping
the leaves from the trees.

A. P. Sturtevant (August 28): If the coming winter and
spring arc favorable an increase is expected next year in the
number of grasshoppers, at least in parts of .7y:"ingb

A. P. Sturtevant (August 28): It is expected that more than
the normal number of grasshoppers may be looked for in Colorado
next year.

C. '.akeland (July 26): Grasshoppers arc in greater abundance
this year than for several years. Te county agent in Cassia
County has held a rixin; demonstration in one community -,'heri.
.elanoplus mexicanus Sauss. was migrating from range areas
to cultivated crops. The county agent in Jefferson County
has held two or three small demonstrations for the same species
and the county agent of Kootenai County is working with a
,-roup of farmers in poisoning the grasshoppers in small local
outbreaks. Quite a heavy infestation of Camnula pellucida
Scudd. is reported from the Henry's Lake district in Frem.ont
County. Dr. Parker has visited this con. -urity recently and
reports that infestation is severe enough to cause alarm for
another season.























North Dakota


G. F. Knowlton (August 7): C --shoppers continue to be very
abundant in northern Utah, cau' '..g damage to zuar beets, alfalfa
seed fields, and many other crops.

CUT:'.0P1E.P3 (:Ioctuidae)

G-. F. Knowlton (July 28): The pale v-estern cutworm
(Porosagrotis orthozonia .;orr.) destroyed approximately.
acres of dry farm -7heat in a 60-acre field at Fairvi'77.
Other nearby fields were d,-Ged less severely, and mostly
in spots. Larvae stopped feeding atut two weeks ago.

BERTHA AR1,YWORM (Barathra confinrata .al!k.)

H. '7. Riddle (August 14): The three counties in the north-
eastern corner of the State have been reported as suffering
a fairly serious outbreak. There is a much less noticeable
attack this year than at this time in 1929.

Illinois


E. 0. Essig (July 31): The white-l'-ned sphirco .as abundant
in the Sierras in the La-e Tahoe region in June an4 Juil.


J. N. Tenhet (August 20): Injury by Horistonotus uhleri
Horn has been very severe this season, and much new territory
seems to be invaded. Thle infeste- territory seems to be
slowly spreading. Adults of this species have been re:.arkably
scarce this summer. (August 21): Adults of IVionocrepidius
vespertinus Fcb. have been very abundant for the-past six weeks,

K. L. Cockerham (;5uut 5): Soil sifting for the larvae of
Heteroderes laurentii Guer. in the vicinity of Foley has
indicated a population as follows: Per square foot soil 4
inches deep, in early corn an average. of 2f larvae were found;
in similar area in early Irish potato field follow by late
corn an avera:-;.- of 5 lerv. ere found; sirrilar area in grssy
turf indicated one-focurth larva per unit. Since at this
time larvae are small, many are no doubt overlc ked; it is
possible, therefore, that the infestation is gr ater t.chn
indicated by counts so far obtained.

I -. GF.I' (.'..-v lophaga., spp.)

H. B. Peirson (August 16): ,`-ite grubs are very abundant
in a forest nursery at Orono.

Virginia


Indiana




Illinois




Kentucky



South Dakota

G. E. Gould (August 23): Red spiders are still doing
serious damage to bans.

.... L. W. Brannon (August 13): Red spiders have been more
injurious to beans this season than for several seasons.

E. W. Mendenhall (August 5): On account of the long drought
.the red spider mites are very bad on blackberry and raspberry
plants at Falloway, Franklin County. The leaves are a sickly
yellow color.

J. J. Davis (Auot 19): Red spiders ruined a commercial
crop of beans at .nrdianapolis, according to a report dated
August 5. This pest was also destructive to elder at Frankfort,
July 25, and abundant on red maple at Sullivan, August 5.

W. P. Flint (August 16): This mite has been much more
abundant than usual, causing severe injury to evergreens,
various ornamental shrubs, and, in several cases, to commercial
apple orchards.

M. L. 1Midlake (August 23): Red spiders are very abundant
on hydrangea, lily-of-the-valley, morning-glory, and other
plants.

H. C. Severin (August 17): Red spiders are extremely abundant,
and many garden.plants, small fruits, and plums have been
injured.

2. H. Swenk (July 15-August 15): The red spider was com-
plained of as injuring spruce in a number of instances in
eastern lebraska during the latter half of July.

R. W. Harned (August 22): Many complaints in regard to
infestations on cotton and orn.mental plants of various
kinds were received from all sections of the State during
the first 7eek of Au6-ust.

H. E. Jaques (August 20): The Hessian fly is moderately
abundant in Des Moines County; also reported present, but
scarce, -in the western part of the State.

M. H. Senrk (July 15-August 15): The month of July was
extremely hot and dry, and LTiese severe weather conditions had
a very adverse effect upon the puparia in the wheat stubble
fields of southeastern Nebraska. Preliminary counts made in
Case and Clay Counties indicated that only about 20 per cent
of the fly puparia vere still viable the last of July.


WtIEAT STRAW 19ORti (Harmolita grandis Riley)


Nebraska


M. H. Swenk (July 15-August 15): The -heat straw worm
was quite prevalent in the wheat fields of southern Dundy
County during July, but no apparent commercial damage resulted
from the infestation.


R : BUG (Toxoptera graminiur Rond.)


H. W. Riddle (August 14): The green bug has caused serious

Counties.


CORN

CTiiC.i BUG (Blissus leucopterus Say)

A. Lutken (July 30): The chinch bug is reported from
the southeastern section of the State.

R. H. Pettit (August 15): The chinch buf is moderately
abundant in the lower tTwo tiers of counties.

J. S. Houser (August 11): The chinch bug-is moderately
abundant; more inquiries than usual.

T. K. Parks (August 25): Chinch bugs have been damaging
corn in a fe-7 fields in western Ohio. Co .plaints reached
this office during July fro.r Van W7ert County in particular.
The insect has increased in aouniance over last year.

N.. F. Howard (August 12): Infestation by chinch bugs, which
ordinarily cause considerable damage in this area (Columbua),
has been relatively light, :r. T. H. Parks believes that
the chinch bug is coming back but at the present time it
will have to be rated as lighter than usual.

IL. D. Peets (August 18): The chinch bug is abundant on corn
in Lincoln and Copiah Counties.

D. Isely (August 22): The chinch bug is of more than average
abundance and is causing some" serious local injury to corn and
rice in the rice belt.

FALL -oYTOfI!0 (Laovma frugioerda S. & A.)

C. H. Brannon (August 26): This species continues to cause
widespread damage over the eastern part of the State.

A. Lutken (July 30): The fall armyworm ap.-i-ared in the
central and southeastern sections of the State about July 10.

?. H. Clarke (August 16): Serious injury by the fall army-
"jorm was found at Luella, -:here corn leaves were being stripped.
A field of young soy bar.ne had been practically destroyed. In-
jury to cotton was the most severe; ra:-.ed feeding ar-as oc-
curred on the leaves, but the most severe injury w.s being
done to the developing bolls. Thre,. larvae -:ere found fe:ini
in a single boll. NTum rous caraI id- larvae -ere present and were
destroying many of the army-orms. The carabid larvae were also

noted to be fe" on the larvae of the arx.,-orm that
had enter'_ t--. soil for pupation.

",' S. Yeomans (August I1): Heavy infestations in the
lower part of the State -'ere reported during July. *.any
complaints from the middle section of the State are beinr
received at this time.

0. I. Snapp (August 13): Reports of damage in Peach
County and adjoining counties are still being received.

J. R. i.atson (August 25): The August brood was not nearly
so large as the Julv brood.

J. %M. Robinson (August 26): The heaviest infestation on
record in many localities in the State occurred from
August 11-26. Infestation general over State.

R. -. Harned (A-'.st 22): Infestations occurred in practi-
cally all section ,f the State durini- August. In some
instances corn, sorghum, soy beans, and peas have been
severely injured.

F. P. Arncler (August 18): An outbreak occurred in the
Gulfport district the second -eek in August. Some of the
paved streets in Gulfport were covered with the .7oi-.s.

--ui>;C,'G" (Cir'jhis uniouncta H-aw.)

Er. C. wouldd (August 26): The first armyporms were ob-
served on AuZust 5 and by August 8 reports of injury had
been received fro-. rmany parts of Princess Anne County. Severe
injury occurred in szv:ral instances to millet, sudan grass,
alfalfa, and corn. Most of the larvae had disappeared by
August 12 and at present moths are abundant.

L. ;7. Brannon (August 13): A serious outbreak of the ary-
Torm occurred in this section during the pastreVk._. I.ore
numerous this season than for the past several years.

CORCN AR .EAR.. (Heliothis obsoleta Fab.)

Geneva Experiment Station (August 15): Th- corn ear -cr-
is moderately abundant in western ITe'- York.

A. G. TRu--les ani assistants (August): Reports of moderate
at-unIance have been received from several localities in the
southern part of the Statu, and .7. A. Dickins reports this
insect as very abundant at ',indo:-.

H. E. Jaques (Auust 20): The corn ear worm is very

abundant in Des Moines and Polk Counties and moderately
abundant on corn and tomatoes in the central and southwestern
part of the State.

C. N. Ainslie (August I): Field corn in this region
(Sioux City) shows an almost complete absence of the ear
worm this year, in fact not a single case of infestation
has been found during inspection of cornfields. Early sweet
corn was attacked to a slight degree but much less than
normally. Corn husks grow compactly this year and this 7ray
repel the larvae.

D. Isely (August 22): The corn ear worm is unusually
destructive this season, in its injury to both cotton bolls
and corn. The most serious injury noted to corn was in an
80-acre field in Pulaski County in which the entire grain
crop was destroyed owing to cutting off of silks by the
worms, apparently before pollination had taken place,

LSSC? CO.:T STAkUL: BC'R (Elasmopalpus lignosellus Zell.)

J. R. Watson (August 25): This insect has been rather
troublesome to cowpeas and other crops.

R. 'V. Harned (August 22): Several complaints have been
received in regard to injury to corpea and bean plants.
These complaints came from Stone, George, and Jefferson Davis
Counties. Corn plants injured by this species were received
on August 13 from Durant.


C002T ROOT APHID (Anuraphis maidiradicis Forbes)


Nebraska


M. H. Swenk (July 15-August 15): The corn root aphid was
quite injurious this summer in Kearney and Harlan Counties.


CORN ROOT ",CR.3 (Diabrotica upp.)


Nebraska


M. H. Swenk (July 15-August 15): The outstanding entomological
trouble in Nebraska during the period here covered was an
intense outbreak of corn root worms (Diabrotica spp.) in
southwestern Nebraska. The prevailing species was D.
virgifeia Lec., which did considerable injury in this same
section in 1927, and a little last year. A considerable
smaller number of D. longicornis Say were present in the
region, and an entirely new corn root worm, D. filicornis Horn,
described years ago from ITe- Mexico, contributed heavily
to the injury, especially in Chase County.

A correction: The note on the alfalfa weevil by G. G.
Schweis in the Insect Pest Survey Bulletin, page 275, s-cond
line, should be corrected so that "fruit crop"' will read
"first crop."

G. G. Schweis (August 19): The alfalfa weevil adults are
more numerous than during the preceding two seasons.


CC.77PAS 1 SOY .E:\S

VELV'ET3:A., CATERPILLAR (Anticarsia &em-atilis Hin.)

H. Spencer (Au-ust 19): The soy bean worm or caterpillar
has appear:-! again at Baton Rouge and in Iberia Parish.
Larvae are of all sizes, and are much more numerous than
those of a previous brood, which appeared here the middle
of June. Soy bean leaves have many ragged holes in them,
but so far the dar-age is less than it -as in 1929, -hen
stripping of the plants occurred over a large area. To
avoid possible loss of the hay crop, the soy beans are
being cut and cured early this year.

C. H. Branon (August 26): Very severe damage from this
species is -idenced by large numbers of specimens sent in
from many sections of the State.

J. IT. Tenhet (August 21): In some fields the coopea
pod weevil is severely injuring co--peas.

J. M. Robinson (August 26): The corpea curculio is very
abundant oier the State, attaching field peas, soy beans,
lima beans, and snap beans.

H. Spencer (July 29): Several reports of the occurrence
of the cotton leaf worm have been received. This insect
has appeared near Carencro and Ridge in Lafayette Parish
and in Cam-eron Parish.

.. W. Harned (August 22): B3gin:ing with July 28 complaints
acc):.panied by spkci.ens of the cotton leaf worm w"re received
every day through Auguot 9. Since that date a few scatterin;

reports have been received in regard to this insect, the
latest one being August 18 from Clarke County. The in-
festation as a whole was not a very heavy one, but in some
localities the worms vere abundant enough to demand control
measures.

C. F. Stiles (August 19): The cotton leaf vworm is
moderately abundant in central and southeastern O':I';1.:,.

Indiana











Illinois


Geneva Experiment Station (August 15): The codling moth
is very abundant in the Hudson Valley and western New York.

.'eekly News Letter, N. Y. State Coll. Agr. (August):
Severe da:-w--e in both the lower Hudson River Valley and the
lake region is being caused by the second-brood larvae.

L. A. Stearns (August 18): A partial third brood will be
developed this season.

C. H.. Alden (August 18): The codling moth is moderately
abundant at Cornelia. A heavier infestation than at this
time last y3ar.

E 7. ",3e':-er and G. B. ::errill (August 27): The codling
moth is modf:ately abundant, infesting pears, at Lake Butler;
caterpillars are quite abundant.

T. H. Par:s (August 25): The codling moth is on the
increase in all parts of the Stde. Injury is severe in
Lawrence County and growers have been handicapped in
fighting it owing to a scarcity of water for spraying.

J. J. Davis (Au.-ut 19): The hot, dry conditions have
been unusually favorable for the codling moth and we may
anticipate considerable late damage. This insect is very
abundac-t in southern Indiana.

F. H. Lathrop (August 12): Infestations in the Vincennes
area have gradually increased during the season. At present
there is serious infestation in some of the apple orchards.
Mir. Sazama estimated that this insect is more abundant than
at any time since 1926.

F. H. Lathrop (August 13): In the Hudson orchard at
Parkersburg there appears to be very nearly 100 per cent
infestation of the fruit. By -xamination of 40 apples from
one tree we found 116 codling moth eggs. A considerable








proportion of the eg-cs '.,.-ve apparently dried up instead
of hatc':ir.:-, probably as a rs.lt of the hot, dry -,eather.
7. P. Flint (Agust 16): T-.e extreme dry weather of the
:t month s be"n s -ome'wat favorable to the codlirn- moth.
The- insect has been increasing on the -hole and is slightly
more abundant t". .-. usual for this date. ".ell sprayed' orchards,
ho-ever, cre very clean in all --rts o& the Stote.

Ken.tucky F. "-. Lathrop (August 12): At present there are serious
infestations in some of the apple orchards in Henderson
Count ,'.

Arlansas A.J. Ackerman (August 11): The codlinrg : oth caused
serious daia-:e last year following the first brood and this
year it appears that the insect will be more injurious :Luring
the late season.

Zansas P. :.. Gilier (.u.ust 14): The codling moth is preent
in as great abundance as ':as expected by the very early season.
The dro-' t has had the effect of somewhat increacing the
infestation over what it would have been in a normal year.

Idaho C. *,alela.ad (July 26): Codling moth developments have
booean puzzling throughout the year. There were three small
peaks of emergence of adults of the first brood and no time
when their_ 7 3 what 7ould be considered a g--neral heigl.t of
emergence. This condition has made the planning of spray
applications: very difficult. Growers in. .--ral have apolied
from one to -.o more cover sprays than ordinarily and control
to date is ex:ceptionally good.

Neveda G. G. Schweis (August 19): Codling moths are now on the
wing; unsprayed fruit is 100 per cent wormy.

Y ,LLC..-:-CKTD C.T3RPILIAR (Datana ministry Drury)

Vermzont H.L. Bailey (August 26): The yellow-necked apple tre

J. A. Hyslop (August 30): The shot-hole borer has killed
several Japanese cherry trees in Mont.L.,er-, County and is
also seriously infesting other trees -eakenei by the drought.


T. H. Parks (August 25): Complaints about injury from
these insects are coming more frequently than usual. We
attribute this to the weakened condition of trees caused
prolonged drought. Wild cherry, peach, and plum are the
affected,


by the

Weekly News Letter, N. Y. State Coll. Agr. (August):
Injury by this insect continues to be severe in the western
part of Niagara County. It has also been noticed in Orange,
Columbia, and Dutchess Counties.

Geneva Experiment Station (August 15): The oriental
fruit moth is moderately abundant in both the Hudson Valley
and westernz l&7 York.

T. J. Headlee (August 15): The oriental fruit moth?_

John Gray (July 25): Twig infestation is very light at
this date (July 23) in ,,ew J~rsey and Delaware, but third-
brood infestation has begun and promises to be very heavy
by the end of next week. The peaki.of the second brood was
reached about Moorestown, N. J., July 5 with 82 per cent
of the peach trees showing larval infestation and 17 per cent
twig injury.

L. A. Stearns (August 18): The third brood is active at

T. H. Parks (August 25): Early varieties of peaches
harvested in mid-August are not seriously infested.

Indiana F. H. Lathrop (August 12): The oriental fruit moth has
not been so abundant in southern Indiana this season as its
activities last summer presaged. It is probable that there
v'as heavy mortality of overwintering larvae as a result
of lo temperatures. Nevertheless, the infestation of
peach twigs by the first-brood larvae was approximately
equal to tb<- of the preceding spring. The second and later
broods fail 1 to increase in numbers to normal expectancy.
Since July 1 there has bee slight increase in most of the
orchards of this area. During the past two weeks, there
has been a slight decrease of infestation in some orchards.
Moths developed from twigs brought into the laboratory
this season are below normal size. In laboratory studies,
the moths do not oviposit freely.

J. J. Davis (August 19):. T'-. oriental fruit moth is very
abundant, especially in southern Indiana.

J. P. Flint (august 16): The extremely dry feather has
apparently been unfavorable to the plum curculio larvae
and emergence from drop spples is very light.

R. H. Pettit (Au.ust 15): The plum curculio is very

CITRUS APHID (Aphis spiraecola Patch)

Florida J. R. Watson (August 25): The citrus aphid, which was
unusually abundant during the early part of July for that
time of the year, has almost disappeared from the groves. This
is due apparently mostly to the activities of ladybeetles
and syrphls fly larvae.

CITRUS WHITEFLY (Dialeurodes citri Ashm.)

Florida J. R. Watson (August 25): The citrus whitefly is very
abundant, mcre abundant than for many years. The months
of July and August have been abnormally dry in Florida,
with the result that the entomogenous fungi have not
been as effective as usual. Consequently, the citrus
whitefly has been more abundant than for several years.

CITRUS RUST I',ITE (Eriophyes oleivorus Ashm.)

Florida J. R. Watscn (August 25): The citrus rust mite is moderately
abundant; mo: 3 common than usual for August. The months of
July and Augi.3t.have been abnormally dry in Florida, 7ith
the result that the entomogenous fungi have not been so

ASPARAGUS BEETLE (Crioceris asparagi L.)

Monthly Lcs Letter, Office of Los Angeles Co. Agr. Comm.
Vol. 12, No. 8, (August 15): Crioceris asparagi,a more or less
serious pest of asparagus throughout central California, has
recently made its appearance in Southern California at Bell.
The owners of the field w;ere inclined to believe that the
beetles have been present for several years, but this is the
first season that they have caused sufficient damage to attract
attention. The principal dama-e was found to occur late in the
season and to be due to the feeding of larvae and adults on the
foliage of the older plants. In northern fields the principal
damage is to the new sprouts.

showed the pest io be well distributed over the Connecticut
Valley region of Hampden County. Isolated infestations were
noted in bean fields along the main automobile hihv.-avs
leading east and west from the Valley. In August .:.i-ration.
led to an. appearance of the beetles in fields throu'rh Har.shLre
County in the Connecticut Valley region just above Ka-.rden
County, and one or two instances were discovered in Frar.:lin
County,, whjh.ise the northernmost Connecticut Valley county.
In addition the area in BErks-.ire County'where th. pest was
found last year has increased to a considerable extent.

.. Britton (A'ugust 25):. This pest is found in small
number end is apparently now distributed throughout the State,
though not found in every bean patch.

'.eekly iErs Letter'N.: Y. State Coll. A.r. (August): The
-..:ican bean beetle can be found over practically all of Orange
County on wax, string, and lima beans, though the infestation
is not serious. This insect has also been noticed in
Chautauqua County.

L. W. .Branrnon (August 13): The ::exican bean beetle
infestation is much lighter than last season on the Eastern
'Shore of Maryland.

J. A. Hyslo (Au-ust 29): Il.:=:z-can bean beetle has practically
disappeared in Lent -c'-;cry County'.

Q. Z. Gould (X;jU-ust 23): The hot, dry weather of this
season appears to have held the bean beetle in check. No
reports of serious damage have been received and few beetles
are precent in the fields.

L. W. Brannon (August 13): The ".:exican bean beetle has
apparently been affected by the drought and accompanyingr
extreme temperatures more than any insect in this section.
The infestation in the :7crfolk tr-,'kin section is much
lighter than last season.

L. M. Peairs (August 27): The iviexican bean beetle is scarce

M. H. Swenk (July 15 August 15): Eoilachna corrupt
was found in Scotts Bluff County in August, 1927. It could
not be found in either the sumner of 1928 or in that of 1929,
but reappeared there in early Aigust of the present summer.
Damage is decidedly local, coTm-cnly being on only a few plants
in one part of the field, usually near the road or an
irrigation ditch. The infested fields lie south of Lyman and
south and east of Morrill, in Scotts Bluff County, according
to a recent survey made by Prof. Don B. ';helan.

single flea beetle.


HI..,,JORilS (Protoparce spp.)


Tenne s see


A. C. Morgan (August 13): The catch of hornworm moths, at
Clarkville as compared to previous years, may be correctly
estimated from records taken from a location which has been
provided with traps for the three years 1928 to 1930. During
1928, at this location, July 12 to August 12, 433 moths were
caught; in the same period in 1929, 1,222 moths were caught;
during this same period in 1930, only 101 moths were caught.
It might be of interest to note further that from July 12 to
July 30, in 1928, only 18 moths were caught, while during the
same period in 1930, 51 moths were caught. From July 30 to
August 5 the increase in the catch was about the same as in
previous years, but from the 5th on the catch has been
practically nothing.
Last year an infestation record of fields outside our
control area showed an average of 57 small worms end eggs per
plants; this year the average was 11 eggs and small worms.
Unless there are very general soaking rains, an infestation of
eggs and worms on sucker tobacco can not be look-d for, which
will very greatly reduce the numbers of moths for next year.


TOBACCO BUJ.70BM: (Heliothis virescens Fab.)


Tennessee


A. C. Moargan (August 13): No recent tobacco budworm injury
has been observed and while this insect is not very injurious
