The localized outbreaks of grasshoppers reported in the last number of the
Survey Bulletin have developed to somewhat serious proportions in parts of the Middle
Atlantic and Fast-Central States.

The results of additional Hessian fly surveys have been reported from New York
and Illinois. The New York wheat belt is much less seriously infested than was the
case last year. In the 16 counties surveyed the straw infestation this year is about
1.5 per cent as compared with 5,9 per cent infestation last year. In central Illinois
the situation is much more serious, the infestation there being much heavier than
.ast year.

The second brood of the chinch bug promises to do little damage in the Ohio
iver Valley and East-Central States. No serious chinch bug situation has developed
In any of the important corn States.

The corn aa.iOyrmis again abundant over the northern limits of its range,
being reported as mszr serious than it has been since the last bad outbreak of 1922.

The clover seed chalcid is doing considerable damage in the alfalfa-seed-pro-
ducing sections of Arizona, as high as 50 per cent of the seed being destroyed in
some fields.

Codling moth infestation is reported as generally more prevalent than during
the last three years in the East-Central States.

Massachusetts and Ohio report unusual prevalence of the plum curculio, whereas
reports from Georgia indicate that this pest is very well under control in that State.

The potato leafhopper is producing serious hopperburn in the potato-growing
sections of Ohio, Indiana, and Wisconsin.

The Mexican bean beetle during this month has been found in two additional
counties in southwestern Pennsylvania. It is now known to be present in five coun-
ties in that State.

Boll Weevil infestations in the infested areas have increased rapidly during
the last fifteen days, owing to general field migration. The only serious injury so
far reported is from southern Alabama, east-central Georgia, and the Coastal Plain
ection-t of the Oarolinas.

Boll worm injury seems to be more prevalent than usual in the Mississippi
Talley and Texas.

The cotton vrorm i generally .t--ei-ely prevalent over the es.itire cotton belt,
east7,ard to Alabama.

In this number is an interesting report fro.i Porto F.ico of v-ary serious
infestation of sugarcane by the s-ija:cane leaf sole.

In the Cape Cod section of ,,issachusetts the el-. leaf beetle is seriously
1rc,.ning the trees and in Fresno County, California, the, pest is ccnpletely defoli-.
atinr. all untreated trees.

The locust lecsf miner see:.:s to b'e generally ab l.dar.t over the entire eastern
part of the United States.

The European earwvig colony in Fast Aurora, New Tork:, is apparently spreading.

The grasshopper situation in British Columbia is serious and severe outbreaks
are anticipated in 1926. From 100 Mile House to Quesnel the roadside gr&ss.oponer,
CO=nuIa nellucida (Scudder), is extremely abundant, and from Chilcotin to Vernon,'
grasshopper outbreks are either in pro~gess or are expected to develop next s-uner,

The western wheat-stem sawfly is proving of considerable econornica importance
in the Province of Saskatchewan this year.
The -oiro1ar>n red mite occurred in outbreak fo.m in the Niagara district and
southwestern Ontario this scu-mer and cavsaed serious injury to the foliage of Daropean
pl.,..s and apples.

The mit.e: Tetranychus telarius.Linn. has become very numerous on hops at
Sardis, British Oolumbia, due to the hot dry weather.

The Hecsian fly has been found present over practically the whole of the
Fraser River Vall..-y, Tew Brunsi-ick,froma Fre.ericton to Grand F.Is. It -:as also
note! at West Devon, Prince Edrward Isl.ri. The infestations -ere li'-,t, varyin- *
from one to three per cent.

'the :Ti-*.ra district, Ontario,. even in orchards usually subject to severe attack.

Cut'jr:;-.s are reported as troublesome on truck cror3 in the Fraser River Velley,
British Columbia.

The Colorado potato beetle has be,= relatively unimportant in northern
Saskatchewan this season.

Potato leafhoppers have been generally abundant and injurious to potatoes
in southwestern Ontario.

The oat thrips, Anrrhtthri-s obscurus M.iller, caused twenty-five per cent
loss in some fields of oats at Richmond, Prince Edward Island, in mid-August.

The larch smifly, erichsoni Hart., is causing severe injury
to larches throu&-out New Brunswick and Prince idward Island, ap=-arently all the
larches being affected.

The maple leaf cutter, Paraclenensia acerifoliella Fitch, has caused severe
injury to maples in southeastern CQuebec.


CI.AS SHOPPES (Acridiidae)

Maryland P. 3). Sanders (Aurast 6): At Clearspring 40 acres of alfalfa and
80 acres of yov-n- apple trees were heavily infested by Mzlanonlus
f':'-rubrjim DeG. Apple trees were bein- completely defoliated
and spots in the alfalfa field had been eaten dov-n to main stems.

Gcorgia Oliver I. Snap? (July 14): In several fields at Fort Valley grass-
hoppers have considerably damaged field corn. They are mcre abund-
ant this year than usual.

Ohio T. H. Parks (Auguast 19): Wet weather has held the grasshoppers in
the meadows ane. stubble fields so that very little damage has been
done to corn. Young clover and pastures have been darimaea. The
grasshoppers are now very abundant in alfalfa in many counties.
farmers have used the poisoned-bran mash with fine success. Corn,
clover, bluegrass, and truck crops have been protected with it.
The insects are most numerous in the southeastern part of the State.

H. A. Gossard (August 24): Grasshoppers in injurious numbers have
been recently reported from Howard, Xenia, Salesville, Leisburg,
Kent, and .Akron. A field of alfalfa at Salesville was reported
as almost ruined and fear was expressed for the safety of all crops
on the farm. A peach orchard at Howard and a young apple orchard
at Xenia were also threatened with destruction by grasshoppers.

Indiana C. R. Cleveland (Augast 21): Re'orts from various parts of the
State continue to indicate that here and there grasshoppers are
troublesome. The county agent at T`okomo last week reported a'
serious irnfestation of grasshoppers on clover and in an adjoining
field of corn and requested a demonstration of control.

A. C. Lor.rn (August 20): Some com)2?.int of grasshopper injury
at Cl-rk-Gville has beer received obu.t not enough to require remedial

*. $wer/k (July 25 to A.uust 25): During the last week in July
a report from Cass County was to the effect that differential grass- (,clanolius differentialis) -'ere gnawing the stems of grapes
and causing the bunches to drop to the -round to such an extent that
the crop was being destroyed.

J. 7. cColloch (A-'.-t 168): Few reports of grasshopper injury
have been received. At Rolla and Elkhart some damage has occurred
to alfalfa. A farmer at Unionto-'n. says the frasshoppers are ruin-
ing a you.- apple orchard by eating the foliage and bark. Four
hundred l-yzar-old trees have been injured.

F. E. Scholl (August 20): During the spring and early su-ier of
this year wrWe had one of the largest ,rasdhopper fights that was
ever carried on by the State.

Arizona News Letter (Tol. 3, :To. 6, June 30): During the month
of June a very successful eradication cam:paign against grasshoppers
was conducted by representatives of the office of the State Entomolo-
gist. -he hoppers b-e,'=n to be troublesome in'the alfalfa fields
near Gilbert during Ilay "but the p-:ak of the outbreak: carie in early
June and ar-ocarLd to be ziors conc.ntrat-Ad in the Goodyear ar.nd Chiand-
ler districts. At the for..,er place the adult hoppers appeared by
the millions in the larze alfalfa fields and in several instances
moved into the neighboring cotton fields. A ntuber of fields of
alfalfa were so badly infested that practically all of the foliage
was eaten off leaving only the bare straws.

The same counties as surveyed last year were again surveyed this
season. last year this region showed a 5..9 per cent infestation
of straw, whereas this year the average infestation was only 1.5
per cent.

W. P. Flint (August 18): The annual wheat insect survey has been
conducted in Illinois during the first two weeks of August. Ex:-.nin-
ations were made in 37 of the principal wheat-growing counties in
the State. This survey shcw-o:T a heavy infestation by the Hessian
fly in wheat stubble in the central counties of the State, with a
moderate to light infestation in the north, ard a light to very
light infestation in the e:trerre south. Parasitism varied from
12 to over 50 per cent. Very little volunteer wheat was found
in any part of the State. All fly found were in the pulparia.
In central Illinois the increase in infestation is quite marked
over that of last year with but little change in the northern and
southern parts of the State. Apparently emergence will take place
at about the normal time if the present rains continue.

-, W. McColloch (August 18): The results of a recent Hessian fly
survey bas.i or, reports made by 604 farmers show that at least 30
per cent of the total wheat acreage of the State was infested.
The eastern third of the State showed infestation running from 3
to over 60 per cent. The heaviest infestation was in the central
and west-central counties v-here the infestation ran from 60 to as
high as 97 per cent. In the eastern quarter of the State damage
ran from 1,000 to 100,000 bushels to the county, whereas in the
heavily infested region in Kansas infestation ran from 500,000 to
over 1,000,000 bushels to the county. Reports from 21 counties
give a grand total of 6, 538,000 bushels loss i'ae to this infesta-

STI?;I WFAT SA^WFI, (Ce-hu" cinctus Norton)

R. L. Webster (August 20): reportss of severe damage in Pierce
and Divide Counties to spring wheat ha7ebeen received.

JOPiTVOR7A (Rarmolita tritici Fitch)


W. P. Flint (Augtast 18): The wheat insect survey has sho-n the
jointworm confined very largely to the same areas of the State
where it was present in 1924. The infestation has increased
slightly in the northwest central and souithein counties.-, ,0



some of the southern counties as high as 50 per cent of all wheat
culms were infested. In the northwest central counties 5 to 18
per cent. Parasitism was lower than last. year.

WrST2N I7HZT ST1.1 MAG3OT (?7mvyia cereal is Gill.)

M. H. S.'vern< (July 25 to August 25): Some belated reports indicate
more eXtensive dara2e during June by the. western wheat.-stem maggot
than.was indi.-ated in my report of June 25.

A WHITE C-GRUB3 (hyllolhaa lanceolata Say)


J. W. McColloch (August 19): The grubs of this beetle are very
abundant inia 30-acre field which is being prepared, for reheat.
They destroyed the wheat on this ground last year.

3LU.1BLE FLOWER BEETLE (Fxrhor.a inda L.)



J. W. McColloch (August 7): The adults are rather common in sweet
corn about Manhattan. In some truck gardens they are causing in-
jury by burrowing into the tips of the ears.
LESSER CORN STATXJ B)RFR (ElassTrop-alpus lig-el 1is Zesl.)

A. M. Vance and G. W. Underhill ('Aug-ust 10): In our plate of field
corn planted June 12, 28 per cent of the plants were infested by
this insect, and as a result of the ty;.4cal killing of the buds,
such infested plants will produce no corn. Infestation in several
near-by fields of late corn ran some7inat lighter, averaging sliJghtly
over 6 per cent. Moths of the second brood have been in the field
for several weeks.

CHINCH BUJG (B1 ss. s _leugcorterus Say)




T. H. Parks (August 19): With the best prospects for a corn crop
this State has had in years in northwestern counties, the chinch
buag is scattered through the corn and making very little impression
upon it. No damage will come from the second brood.

W. P. Flint (Auaust 18): The weather of late July and the first
part of August has continued favorable to chinch-bug development,
whereas practically no da-mage will occur from the second-brood
bugs this year. Apparently sufficient numbers of bugs will go
into winter quarters in many sections of the State to cause some
injury next season.

M. H. Swenrk (July 25 to 25): Although the migration of the
chinch bugs (Blissus leucoptetus) from the small grains into the
corn crops was largely over by July 10, and most of the bugs had
gained their wings a few days later, there were some reports of

continued injury in corn and cane fields during the remainder'of
July. Some rather important injury of this sort was reported
from Phelps and Harlan Counties, west of the main area of daraSo
as given in my report of July 25, during the last week in July.
The second generation of this pest is doing damage in the corn-
fields of southeastern Lancaster County at the time of the for-
warding of this report. Many bugs of the second generation
have become matured at this time.

CORN EAR WOPI! (Heliothis obsoleta Fab.)

P. R. Lowry (_ugurt 10): Half a dozen larvae sent in from a
small patch of sweet corn. This is the first record of this
species in the State since 1922.

W. P. Flint (August 18): There has been very little increase in
injury by the corn ear worm during the past month, a light infesta-
tion occurring in sweet corn fields, but no very serious damage to

E. L. Chambers (August 20): Several complaints have been received
from growers to the effect that this pest has made its appe-r-rnce
in southern Wisconsin, but little damage has ben done as yet.

A. C. Morgan (August 2C): The corn ear worm was quite injurious
in the buds of the you=Ig corn in late July at Clarksville.

F. L. Thomas (August 19): Two or S worms to every head of milo,
great numbers in the corn. Also reported from Lubbock, Fall,
Wichita, Cass, Panola, Tyler, and Brazoria Counties.

T. D. Urbahns and assistants (August 19): In Mendocino County
the corn ear worm is attacking corn and doing severe damage.

COlT3 ROOT WOPi. (Diabrotica longicornis Say)


M. H. Swank (July 25 to August 25): During the last week in July
we received several reports of serious injury to corn by the ve;tern
corn-root worm (Diabrotica lon icornis) from Dundy County, in the
extreme southwestern p-rt of Nebraska. Many fields were reported
as affected, the damage in some cases being estimated as fully 20
per cent of the field destroyed. One seventy acre field was at-
tacked both by the western corn-root worm and the seed-corn beetle
(Agonoderus alliess, the latter also attacking the root system
of the corn, and in combination these two pests t-hreatc:end to des-
troy the field. Injury by the western corn.-root woxm was also
reported from Kearney County. This pest as a rule is not serious-
ly injurious so far to the westward in Nebraska.

- 302 -

AWMY17ORM (Cir-phis mnipuncta Faw.)


W. P. Flint (August 18): A small outbreak of armnyworms occurred
in the south-central part of the State, being confined largely to
Coles and Douglas Coamtics. Practically all injury occurred in
cornfields, and was not of a'very severe nature; the lower leaves
were eaten from the corn, but little if any reduction will be made
in the yield.

COPJT LEAF APHID (Aphis maidis Fitch)





M. H. Swenk (July 25 to August 25): During the first half of
August there were reports of a destructive abundance of the corn
leaf aphid (Aphis maidis), working on the corn tassels and other
parts of the corn plants, in Seward, Saline, and Nuckolls Counties.

J. W. :cColloch (July 30): Cornfields in Reno County are reported
to be rather generally infested by this aphid. In some cases the
tassel is not emerging from the foot owing to the abundance of
this pest.


YTLLCW'-STR.PED AiT70PR1 (Prodpenia ornithogalli GCaen.)

J. W. McCoiloch (August 18): A rather serious outbreak of the
cotton cutworm developed in this county (Riley) about August 5.
In some fields alfalfa was held back several weeks. Where the
alfalfa was in bloom the worms did considerable damage by cutting
off the bloom. Tachinid parasites were very active and from 75
to 90 per cent of the worms bore eggs. At present (August 18)
the worms have nearly all disappeared.

WESTER!T Y3LLOW-S'F.IP= A.-ff70PIOr (Prodenia praefica Grote)
A. 0. Larson (July 31): This insect was serious in Merced and
Stanislaus Counties in 1923. it is becoming serious in Merced
County this year, attacking alfalfa, beans, watermelon, grape-
vines, and yor-nr peach trees.

AT.PALPA CATERPILTAR (DurvmuE eurytheme Boisd. )


A. 0. Larson (July 30): While driving north through the San
Joaquin Valley on July 30 I not3d that many of the -adiators of
southbound automobiles were rel! covered with alfalfa butterflies.
This wac interesting bcca'use the butterflies did not appear to be
remarkably numerous and were not on all the machines. A few were
flying about in no definite direction. .fpprrently as many were
going in one direction as in any other. This condition was noted
for about 75 miles but soon after I passed Tulare I came to a very
heavy infestation of the butterflies. They were literally swarm-
ing over the alfalfa onr. both sides of the highway. Here was where
the automobiles were catching the butterflies, Yorth of Kingsburg
they were again less numerous but they were quite noticeable the
next 115 miles or as far north as Modesto.

CLOVER SEZID CHALCID (Bruchophai funebris How. )

Arizona i'c-s Letter (Volume 3, No. 7): A noticeable increase
of the alfalfa seed chalcid fly has been .reported from the Yuma
district. Reports also have reached the office that this insect
has been very destructive to the alfalfa seed in the Chandler
district of the Salt River Valley. As much as 50 per cent of
the seed has been destroyed in some fields.


J. W. McColloch (August 18):

Reports from Alton and Falun indicate

VAFLIECATD CUTJ7OD (Lycophotia margaritosa saucia Hbn.)

T. D. Urbahns and assistants: The variegated cutworm is attack-
ing gardens and alfalfa in Modoc County, being severe in places.
Dna.age first noticeable about June 15.


FALL APR-IWOPIM (aiph;a frurinerda S. & A.)

South Carolina

Philip Lagiubill ard T. 0. Shiver (August 21)- The fall army-
worm is attacking velvet beans at Columbia in a field containing
100 acres,

A'R9!M7 (Cirleis uninuncta Eaw.)

South Carolina


Cal ifornia

Philip Luginbill and T. C. Shiver (Auguast 21), A field of 100
acres in Congaree River bottoms about 7 miles from the city is
attacked by this insect. Slight damage is being done.

T. D. Urbahns and assistants (August 15): Adjoining fields of
alfalfa were cut and migration of the worms to the h?.:3s took
place destroying as much as 10 acres of beans in one night at
Escalon, San Joaquin County. Growers are using furrow method
and poioned-bran mash for control.


T. D. Urbahns and assistants (August 15): Several fields in
Escalon-Yanteca districts heavily infested. Growers :c using
various contact insecticides with varying degrep3 of contre-1.
Sample of insect sent to Geo. Wilson for identification.

GREEN CLCVE '0PF! (PtLthroen.'a scabra Vab. )

South Carolina Philip Luginhill and T. C. Shiver (August 21): A field at
Columbia containing 100 acres was attacked by this.insect.
This same field was also infested with true ani fall armyiorr.s.
Considerable damage is being done.


AN APHID (Ahis medicaainis Koch)

Indiana C. R. Cleveland (August 21): i"eports, including specimens of
the coapea or locust aphid (Aphis r.edica: inis), have been received
from several points in the State that this -aphid has been abundant
and injurious on cowpeas during the past month.


IrISQUJITE B .N IOTH (sp. undetermined)

Texas 0. G. Babcock (July 28): largest bean crop in at least five to
6 years in vicinity of Sonora, Ozona, Fadorado,and Pocks Springs,
Texas. To date (July 28) there seen" to be two crops of the
mesquite beans as well as two broods of the mesquite bean pod.
moth. Parasites very numerous, hEnce holding in check the
ravages of the moth larvae. Loss probably less than o6f 1
per cent.


APPLE FRUIT CHAFER (Mctq'chrcrna interruntum Say)

Indiana B. A. Porter (August 8): This insect caused considerable damage
to the fruit of a few apple trees in an orchard near Decker during
the early part of July.

APPLE FL7A WEEVIL (Orchpstps pollicorn.s Say)

Indiana B. A, Porter (August 8): Most of the weevils entered hibernation
between July 10 and 15.

APPLE APHID (Arhi sli DeG.)

Ohio H. A. Ocsslrd (August 24): The green apple aphid became r'quite
generally noticeable o-cr the northeastern section of the Etate
during June, July, ond early August. Hundreds of trees in many
orchards wore blackened by the funtpus growth in the honcydleo7.
They wcre particularly r.notei at Pavenna, Thardon, Painc:ville,
Cleveland, and Berea. They were most numerous about the first
of July and at the present tiie harelargely subsided.

WOOLLY A4PPLE APHID (Eriosona ) an gerun Laiusm. )

E. W. Mendenhall (August 20): I find that a great deal of apple
stock in the nurseries south and i with the woolly aphid, especially the aerial form.

CODLING MOTH (Carrocapsa pomonrl'.a L.)

T. H. Parks (Auguist 19): The plum curculio, tog,-eth-r with the
codling moth, is solving the market problem of apples grown in
the uncared-for fanm orchard. Fr2ctically no unsprayed fruit
is free from attack and the insect is causing losses in some
well-sprayEd orchards.

B. A. Porter (August 8): Although the codling moth got a late
start in this section (Vincennes) with reference to the blooming"
period of the apple, conditions since the beginning cf the entrance
of the worms into the fruit have been verj favorable to them, and
the irfestation in most orchards is unusually severe. According
to banding records, there has been. no definite breach between the
first and second broods.

W. P. Flint (August 18): As indicated earlier in the s9%Ler, the
codling moth is more abundant this season than during the last
three years. Some poorly sprayed orchards show a fairly hi,:h
infestation, mainly by late worms from ., which have hatched
during the last two weeks.

APPLE AND THORN SIELTOIIZEF. (Thkerorhla rn.- Clcrc:)

P. R. Lorry (July 29): Injuring tip of branches of nearly every
tree in an orchard at Hollis.

A. I. Bourne (August 22): The first moths of the second genera-
tion of the apple and thorn skeletonizer were making their appear-
ance about the 30th of July. We are finding that the pest is
just about as abundant as was the case last year at the corres-
ponding period of seasonal develo--.ent. The ease r7ith rich
this has been controlled has led our leading fruit ro-'ers to
rank it among the more or less- secondary pests which they have
to consider.

RED-BA:TED LEAF RTOLLF- (Sila velutinana Walk.)

B. A. Porter (August 8): This pest continues to be present in
most orchards in smrill n'mbcrs. T.c outbreak at Vinconnes re-
ported earlier'stolped with the first brood, the second being
present in only very small numbers.

- 306-

FAIL E (.0. y (Hyphantria cunea Drury)






A. I. Bourne (August 22): The fall webworm is slightly more
abundant than has been the case for several years.

C. R. Cleveland (August 21): The webs of this insect are a
very corn'ron sight on appla trees and shade trees throughout
those portions of central and northern Indiana which have been
visited by the writer. Portions of trees and branches show
considerable defoliation.

YELLO'71-iTEC:-D CATE IILLAR (Datana ministry Drury)

E. W. Mendenhall (August 5): I find that Dptana ministry is
quite troublesome in a number of orchards in the central and
southern portions of the State.

SAXT JOSE SCAIE (Aspidiotus perniciosus Const.)

B. A. Porter (Augast 8): Second-brood crawlers began appearing
about July 12 at Vincennes. The unseasonably hot weather in
early June, when the first brood of crawlers was appearing, ap-
parently caused the pest to multiply much faster than is usual
with the first brood. Serious infestations are dev3'loping in
a few orchards in this section.

EUEOPEA1T ND MITE (Paratetranychus pilosus C. & F. )

A. I. Bourne (August 22): The European red mite, for some reason
or other, quite generally over the State, has jumped aead in its
abundance d-.ring late July and early Aug'.st. As a result, the
characteristic bronzing of the foliage is berinrin. to --e its
appearance in very many of our orchards. In general the pest
is not serious in orchards here the oils were tho:-i,*l.ylly _-plied.
It has been the custom of some fruit growers to so--p Pc-.e of the
blocks in secsons where there is little expectation that there
will be any fruit. It has been noted that the mites i-avo gotten
their start chiefly on those trees which were not given attention
at the proper season.

Oliver I. Snapp (July 14): Over 8,500 cars of Georgia peaches
have moved to date unusually free of plum, curculio larvae. The
insect is apf'rently under most excellent control. There are
no small larvae in the Sibertas that are now moving, and other
observations point to an absence of a second generation in Georgia
this year. The absence of a second crood is attributed to the
very unfavorable leather conditions during the pupation season,
which caused first-generation adults to be late in emergir.g from
the soil. (Au-.i.St 15): The very dry and hot weather has been
most unfavorle for the development of adults in the soil. IThe
general curc-alio infestation in the Georgia Peach Belt is lower
than it has been for seven years.

T. H. Parks (Auguast 19): This insect, together with the codling
moth, is solving the market problem of apples grov',n on the uncared-
for farm orchard. Practically no unsprayed fruit is free from
attack and the insect is causing losses in some well spraycd


RED SPIDEI (Tetranychus sp:'-.)

Weekly 'News Letter, State of California, "/ol. 7, 1o. 17 -, ust
23: An infestation fully as severe as that of 1924 ha3 aca-in
occurred during the season of 1925. The red spider has b.3?n
particularly active in many orchards of the Sacrae.nrcto Valley,
causing defoliation of trees and a corres.,oonding reduction of
quality of fruit and loss of crop. Despite the efforts of
fruit growers who have experimented with different spray
materials this pest has continued to spread. It is hoped
that through a discussion of latest methods by members of the
staff of the Department of Agriculture, the Univrr.;inty, and
spray organizations, methods may be devised which will help
to bring it under control.

Oliver I. Snap (July 14): This insect, which is normally very

BOLL WEEVIL (Anthonomus grand s Boh.)

Cooperative report on status of boll weevil and other cotton insects
as of Aui.-st 15V Delta Laboratory, Tallulah, La,
WVeevil infestations in the infested areas have increased rapidly
during the last 15 days as a result of general field migration.
The contained dry weather in many localities has effected complete
weevil control. In Texas injury has been reported in only a few
counties on or near the coast in the southeast. In Arkansas ':spotted"
infestations with injury occurred in only the southern portion. In
northern Louisiana "spotted" infestations occurred with severe
injury in many fields and in the southern portion a high infestation
prevailed generally. In Mississippi injury has occurred locally and
largely in the Mississippi Delta section. Tennessee is practically
free of injury. In northern Alabama, northern Gelrgia, western
fisnth Carolina, and western North Carolina weevil injury has be=1
limited to local areas. Considerable injury has been reported in
southern Alabazrma, southern and eastern central Georgia, the coastal
plain section of Souths earolina, and southeastern and eastern North

Dr. F. L. Thomas (August 14): Reports of injury from boll weevils
come from Fort Bend and Braporia Counties.

A. C.. Johnson: On August 3 in four fields near Port Lavaca an average
infestation of 42. 5 pr cent was found and on August 12 in the same
fields an average infestation of 51.8 per cent.

D. Is~ly (AOiust 15): ,oll wvevil infestations aro still local.
In .. fields in the southe n half of the State surkous injury
has occurred, but the greater part of cotton in 'Ark-aneas is still

w7. R. Sudduth: On August 8 in one field near timber in the
Shrevcn-t z-ction an infestation of 54 per cent wras found and in
one field n:me dA.zt.nce from timber an infestation of 2.7 per
cenro In different fields from the above on Auguast 15 an in-
festation of 43 oEr cent was found near timber and 21 pnr cent
in a field some distuince from timber.
W. 2. Hinds (August 17): No.emergence from hibernation caves has
occurred from A*gust 1 to 15 _nd we have closed these tests and are
now moving our cages. The latest emergence was, I belivo, on
JuTne 12.
Sodium f: oE'licate has given serious burning on cotton -hen
applied with dew on the foliage and appears to have beo-n con-
sid4erably less efficient than calcium arsenate so far as boll weevil
conlrc'l is concerned.
Boll weevil migration has been under way since about July 15 in
corntr-:1 Louisiana and there hasbeen no effective natural control
at any time during the season and weevils have become exceedingly
ahndant. In spite of this fact, the weevils have- been sufficiently
well controlled on regular calcium arsenate dusted plats tc allow
f. -_iting to continue steadily to date (August 15): Practically
no fruit has been set on unpoiconcd fields in the vicinity of
Baton Rouge since about July 20. The setting of bolls has not
been satisfactory in this section throughout the season and re-
gardless of weevil infestation, spacing, or other conditions. The
trouble seems to be due to a combination of moist-re and fertility
conditions which have been more favorable to vegetative growth
than to the setting of bolls.
Probably the latest poisoning of cotton for seevil control in
the State this season* is being done in the extreme southern pert
of the State. In that '-ec-ion two airplane dusting units have
recently begun work in the vicinity of Houma and south of Abbeville.

B. R. Coad (August 15): Goner'Ally, the infestation h.:s increased
during the last 15 days owing to grnral field migration. In-
fistrtions rangc from light to ccmplote. Severe injury h;z occurred
in many fields in lladison Parish.

R. W. HH.rned (Aurust S): during the week which ended -Anuast '

Dr* F. A. Fentoa: Field-to-field movE.ment of the weevil continued
th"car-hout the'past two wee-s, resulting in the heavy infestation
of fields heretcfore only slightly infested. Thi' movem,-nt w;'s
accelerated omer Ii-.rc areas owing to drought conditions which
cauoled:ra heavy :Thedeing of squares and ycung bcr.lls. This latter
cc.-f-Ition resulted in a shortage of cotton forms in which the weevil

COTTO AP'"AID (Anhis _ooroii C-lov.)

Georgia Jeff Chaff in (August 5): Within the last three weeks we have
received a very large number of complaints from cotton growErs all
Over the State concerning the serious damage that is being done by
the cotton lice. They are more numerous and doing a great deal rIre
damage than in any year in the past. This can be account ed for to a


large extent by reason of tle fact that the State of Georgia is
dusting over 50 per cent of her cotton acrengo with calcium ars.nato
in tth control of the boll v- evil, Calcium rscnate kills the lacy
beetle, lcAving the way open for the lice to multiply very rapidly.

V. V. 7illiams (August 17)" Lice -,re noticeable on many plants in
most fields but it is too late for damage,

AX1bama J, M, Robinson (July 31): Plant lice tn cotton have been the cause
of inquiries from various parts of t1-he State.

Louisiana Dr. J. We Folsom (August 15): :o serious lice infestation. Lice are
comparatively few in numbers and most of thes,-- are small individuals.

We Eo Hinds (August If): The cotton plant louse infe action have been
abundant, regardless of poisoning, but aplmrently average considerably
heavier on areas whore several applications of cn.lcium a-rsenate have
been made,

Arizoii. The Ari-onav Tews Lettor, Vol. 3, No- 6, Phoenix, (June 30): A
report was received from Gila Bend that the cotton aphis was becoming
numerous. A request was included for leaves bearing the parasitized
lice which would be distributed in the cotton fields, thus liberating
the parasites as they hatched. Because of the lack of such material
in the Salt River Valley it was impossible to send any relief.

COT__O: FLEA (allu seriatus Rcut.)

CT: 7. D. M, Hcaichc.'n (Aujust 14): From July 6 to 11 six localities in
CT v;:'IZLIT Guorgia, and from July 12 to 23 seven localities in South S:rolina,
were visited to investigate the distribution and amount of hopper
injury. The only pronounced injury found was at Jufferson, Gu.,
and in Anderson County, S. C, Slight injury was noted in Fulton,
DBKalb, and 3orrow Counties, Ga., and in Pickens, G-recnvillL,
Florence, 1airficld, and Kershaw Counties, S. C. The injury appeared
absolutely identical with that dound in Texas.

Mississippi Clay Lyle (July 30): The cotton flea, ,-hich caused serious loss
in Texas, Georgia, and South Carolina last yczr, was recently found
in M1ississippi for the first time, when D. W. Grimes, Ascistant
Entonologist of the St-te Plant Bo'rd, collected specimens of thlis
in.:cct on two farms in Washington County. One farm was south of
Greenville znd the other north of Leland so th.t they wore about 15i
miles ap.rt. Only one specimen was found on fnarm. sE they are very
hard to collect but Ro W. Harnod oxprcsser the opinion that this
insect may be widely distributed in the State alre..dye
The so-called "fleas" are so small and active Zhat thoy arj not
easily seen. The typical injury cause-d by thosu pests is much uore
notijeelc than the insects themselvuG. In the two Washington
County fields the injury was exactly similar to that reported from
Tex-s, South Carolina, and Georgia last yoer. Usually the affected
plants cro0-i very tall and put on practically no limbs or frvit. This
habit of growth is vcr7" chracteristic, though plants are occa'-ionally
stuntcd or dw-jrfcd by this pst.

Clay Lyle (July-30): That cotton worms are already appearing in
this State, seems highly ,probable, according to the following tele-
gram just received by the State Plant Board from Bo R. Coad4 in
charge of the Boll Weevil Laboratory at Tallulah, La.:
"Leaf w7orm invasion has appeared throughout northern Louisiana
within past few days, and 'is' now thoroughly distributed over this
country, undoubtedly over a large portion of Mississippi as well.
Poisoning already started in many' places in northern Louisimn.."
Not a7 single specimens of the cotton woem has yet been sent in
'for identification from Mississippi, and the Plant Board Inspectors
who'examine- hundreds of cotton fields each week hve also found
no signs of cotton worm injury to this date. With this appcar-.nco
in northern Louisiana, hovevor, it will probably be only a few
days until it is reported in Misisissipi,. This post app:c!-red in
Mississippi in July, i923, and stripped cotton fields over a large
section of the State that summer and frll, causing consiicr.-blo
loss. In 1924 the first report of this wor--m in Mississippi reached
the Plant Board office on August 28 and on account of this late
appeoanrance practically no damage resulted last year.

R9 W. Earned (August 5): The first specimens of the cotton worm
were received at this office on August 1 from Adams Countr, Speci-

Porto Rico


A, H. Rosenfeld (July I): Attention of our entomologist, Dr.
H. L. Dozier, was called to a field of 5 acres belonging to a
colcno of Central Caimbalache, near Arecibo, on "Torth CoaEt.
Investigation proved these 5 acres to be 100 per cent infested
tand the cane was yellowed and dwarfed as ff by some blight. All
s t.cs of the insc-ct were present except the males, which even
br_.ding in the laboratory by Dr. Dozier failed tcdevolop. This
is the first serious outbreak of this insect reported on t'ec
island and it would be interesting to know whether it has suiaenly
ad-ptcd itself from some native grass or if its.aprearance in
n-b^ers is due to reduced parasitism for some natural pauso.
Coccinullidao were abundant at the time the patch was sprayed
with kercscne emulsion by the owner with excellent results. Wolcott
(Jo-erno Bd. of Agr. of P. R., Vol. 2, pY)35, April,1921) reports
six individuals having bccn found.

all the locust trees, including large areas in many places. Field


observations upon soybeans in the attempt to find the amount and
nature of the damage caused by the Mexican bean beetle have re-
vealed the fact many areas where the locusts have been
defoliated the adults of the locust leaf miner have begun feeding
very abundantly on soybeans. This has been so noticeable in many
places that it )as been reported by farmers and county agents. The
feeding by this insect is nudh more severe than any feeding caused
by the Mexican bean beetle upon the same crop. To the present time
no egg masses have beer found, deposited upon soybeans and only the
larvae ihich have migrated from other beans *iich were defoliated
have been found upon spybeans. Feeding by the adult has been very
meager in all cases.

T. He Parks (August 19): The lost trefs on the hills of southern

this source is apparently steadily on the increase in the State,
Infestations of root lice are always accompanied by conspicuous

ants are doing the damage.


Weekly News Letter, State of California, Vol. 7, No. 17 (August 2)
Snail control has been extended with success to ridding nurseries
of this pest, according to R. D. Hartman, Superintendent of the
Nursery Service of the California Department of Agriculture.
The common garden snail, Helix as ersa, is considered a troublesome
pest in some Iarts of the State. It attacks many ornamental plants
in gardens and nurseries. The measure recommended for the control
of snails, as given out by the California Department of Agriculture,
is to first spray the premises in the evening with water, to brig
the snails into activity. Then mix 1 pound of calcium arsenate with

E, P, Felt (August 3): Regarding the earwig infestation at East
farora, an examination last week showed the insect to be present,
in one case at least, in considerable numbers ard. apparently somewhat
widely distributed in the village, though no general complaint
has been made and it is quite probable that many simply overlook
the insect. There were very few about the premises originally
reported as infested, though three bloccks away there was a very
considerable colony uncr the loose bark of an elm log kept as a
trap. The insects appear to be more troublesome by getting into
the house or on the laundry than on account of injuries to plants.

Oregon Daily Journal, Portland, (July 31): After having covered
approximately half of the territory within the city limits of
Al-any with earwig poison during an "anti-earwig" campaign last
week, local people have launched a second and "follow-up" campaign will aim toward covering the entire city and killing earwigs
hatchei out since. The poison will be sold at cost at the city
hall, under auspices of the City Government. More than 1,000 pounds
of earwig poison was distributed to local people duri-ng the last
