Althou',i zrasshopo-,rs continued troublesomno durin27 the -1ore"ter part of
Au,:ust, control cai:Tains arc practically closed in most of the Plains States.

The garden webwvorm appeared in largo nu-.bers about the middle of the
month from Indiana westward to Missouri and- clrska.

Sod webworms were very troublesome during: the 1,tter half of the month
from Ohio westward to Mis.- :ouri and Tobraklca, in many instances being partic-
ularly troublesome on golf greens.

The white-lined sphinx avpearod in outbralc nurb,:rs in parts of lown,
o inrz vory destructive to soybeans.
Reports -roccivcd fro-' Iova indicate that the chinch bu- will pro'-'ly be
an oven more serious post in that State in 1935 th'n it ias been this yc!'r.
It is estiFated that over 11 million dollars worth of grain was saved in that
State this y-:r by the control caipaia. Sccond-brood bugs were observed
aoniout the ri0`1e of the month in Missouri, .eb.raska, and Kans!,..

The plum curculio will rd-:b'bly go into hibernation in larger nurnbers
than usual in the Fort Valley -pach section of Geor-4ir .

The rnpc le-fh--,:r is more abundant in 'the .Tia.ara district of :ITew. Yor'_
than it h-as -been for several years.

The tobacco worn is causing serious de-ao to tor.tces in a-rts of lowa.,
iTebraska, and 1civa .a.

Table-stock potatoes in the irrigated section of -'.,-'i.>. have bcen r&duccd
65 percent by the to'iato p.yllid.

The Mexican bean beetle has '"een more abundant and more widely distrib-
uted than over before in Maine. Similar re-orts of infestations have ',en
received. from the Yow Fn ;land and MiU-1'.le Atlntic States, ond it is roportcd
to be moderately bundant throuj-out its r-.c.

Twenty-one additional townships in Washin.c-ton, t-cnobscot, -', in-.
iJldo Counties in Maine, have been found infested by the beech scale.

Danrcre by screw worms is ap.,arently on the incrcea in Florida and i'isis-

GRASSHOPP7F (Acrididao)

Iowa. C. J. Drake (August 2): The three most important grasshoppers in Iowa
are the lessor migratory locust (Melanoplus mcxicanus Sauss.), the two-
lined locust (M. bivittatus Say) and the differential locust (M. differen-
tialis Thos.). Heretofore, the differential locust has been the most im-
portant; but this year it seems that the lesser migratory and two-lined
locusts are responsible for most of the damage. In some localities the
two-lined locust is extremely abundant. The infestation is very spotted.

Missouri. L. Haseman (August 24): Except for Barry and Howell Counties in
the Ozarks, we find none of the three economic species of grasshoppersat
all abundant.

Nebraska. M. H. Swcnk (August 15): The grasshopper situation continued to
be troublesome during the period July 15 to August 15, and, up to the
middle of August, more than 2,000 tons of poisonod-bran bait had been dis-
tributed in 3S counties.

Kansas. H. R. Bryson (August 25): Although grasshoppers can be found in
their usual habitat wherever sufficient green vegetation is present, they
are comparatively scarce for this time of year.

Oklahoma. C. F. Stiles (August 20): Grasshoppers are moderately abundant in
the western part of the State.

Wy-ming. C. L. Corkins (August 21): The survey of the .i.jilt grasshopper pop-
ulation at this time indicates that the outbreak is definitely on the wane.

Idaho. C. W.:keland (August 20): Grasshoppers are moderately abundant in the
southeastern part of the State.

Nevada. G. G. Schwois (August 21): The grasshopper control camp-aign is now
over for the year. The egg survey will start shortly after September 1.

Arizona. C. D. Lcbert (August 20): Grasshoppers (H. mexicanus) are ca'.sing
considerable trouble in the alfalfa fields in the Salt River Valley. This
is either a delayed hatch or a second brood--I believe it is a second gen-
eratiron. Most of this brood are now in the last instar ..:L many of them
fully winged. Poison is still being applied all over the valley.

I'.'MR,'I CRIC:TT (Anabrus simplex Hald.)

California. E. 0. Essig (Augu-t 22): A few specimens of the Mormon cricket
v,-'re found in Matterhorn Canyon, Yosemite ll7aional Park, in July. They
are rarely reported from this State.

AR.:i'.YWCRI. (Cirphis nunipuncta Haw.

Ii.'l J. J. Davis (AP-t 24): T!*.- armyworm was destructive to corn on
bottom land. near Boonville oon August 15.

- 215 -

Illinbis. L. H. Shropshire (Au(gust 20).: Few arm; **- from the central part of the State.

Minnesota. C. E. Mickel (August 27): The worst outbreak in many years has
occurred in the southeastern part of the State. T..-. third generation is
now very abundant.

Iowa. G. C. Decker (August Ir): Armyworms are being reported daily in most
of the counties in north-central Iowla. Apparently, they have bred up in
large numbers in foxtail an'- other grasscs in stubble fields. They are
reported as seriously damaging Sudan and millet fields.

GA:DEN 7E3 '. (Loxostege similalis Guen.)

Indiana. J. J. Davis (August 24): The alfalfa wvieb werm (L. similalis) was
quite destructive in some localities during the period from August ; to
11. Definite records of destructiveness were received from VWhite, Fulton,
Clinton, IMrgan, and Carroll Counties.

Missouri. L. Haseman (August 24): Larvae were abund.ant on pigweed and other
plants late in July and early in August, and during the latter part of
August many moth's have been on the wing.

Iowa. C. J. Drake" (August 2): The garden wbbworm (L. si.ilalis) is quite
common this year. On a farm near Indianola 14 out of 22 acres of soy-
beans were destroyed.

Nebraska. M. H. Swenk (August 2C): A Burt County correspondent found the
alfalfa fields in his vicinity harboring an abundance of moths the second
week in August.

BEET ;:3BW.7RL. (Loxostege sticticalis L.)

Minnesota. C. E. Mickel (August 27): Larvae were very abundant on August 1;
heavy flights of moths occurred on August 10 25.

North Dakota. J. A. Munro (August 19): Beet webworms very abundant on beets,
potatoes, and Russian thistle in Richland, Sargent, and Cavalier Counties.

SOD :,7'FRIES (Crambus spp.)

:Ohio. T. H. Parks (August 2C0): Sod- webw:orm larvae were found injuring bent-
grass on golf greens at Circleville on Auguast 14. Reports of injury with
specimens were also received from one of the golf courses near Columbus.

Illinoi-s. L. H. Shropshire (August 20):' AdIul'ts of several species are very
abundant in northern Illinois.

Kentuck,. M, L. Didlake (August 25): Adults of several species of sod webworms,
including C,. teterrellus Zinck. and C. trisectus Wak'11:., are very abundant,
the latter being most irmerous; damage by larvae not very noticeable.

Iowa.. C. J. Drake (Au-Cust 2): Sod web'wrrms are extremely abundant in golf

21S -

grns at Des Moines, Boone, Waterloo, Cedar Rapids, and other cities.
Pasturc fields have been greatly *injured. They also did considerable
d.amae t. corn in the spring, a:: in the northern part of the State web-
worms are doing a considerable arLcunt of damage to corn planted -ren
gCvernmcnt lani lec-.-i for forage purposes.

1issouri. L. Hasenan (August 24): Moths in considerable numbers were on
the wing during the hottest period of the drought, and at this time we.
are getting complaints of nearly full-fed larvae in golf greens.

NTebraska. .. H. Swenk (August 15): A Clay County crrrcspendent reported
that his previously beautiful lawn had been about destroyed during the
first half of Auust by sod webworms, aided by attacks of a leafhopper
identified as Deltocephalus inimicus Say. He reports that the birls
did good service by digging out the webworms from the dead,.brown sod.

7WHIT:-LTIi-D-" FHIiDT (Sphinx lineata Fab.)

Iowa. G. C. Decker (August I): We have numerous reports of larvae migrat-
ing from weed patches and stubble fields into soybeans and corn. rnc
snyboan field near Webster, City was reported destroyed. Associated with
the sphinx were a moderate number of Prodenia ornithogalli Guen.

C. N. Ainslie (August 22); The larvae are pre-c.t everywhere this
year, and only by continuous watching and hand-picking can serious injury
be prevented.

JAPA.T:7E EETLE (Popillia japonica ITh:.)

Con-necticut. W. E. Britton (August 23): The Japanese beetle is apparently,
more abundclnt in the cities and towns than in preceding seasons. It il
Aot yet cormonly seen in the open country rf Connecticut.



E3IAi1 FLY (Pytophaa destrictnor Say)

Mincuiri. 1,. Haseman (August 24): J. R. Horton reports a 2-percent stubble
infestation in northwestern 1issoiri; 11 perce it in the we-t-central part;
94 percent in the. southwest; 21"percen:it in the southeast; and 1C r-'rcent
in the east-central part. O)ne limited stubble survey in northeastern
14is-oari indicates a stubble infestation of only 1 te 2 percent, with
'practically evry flaxseed ewui.ieI XiGu, due, we believe, to the exces-
sive heat. Limited counts at Coluubia showed 1CO percent mortality of
-.jcrxedr, with t( :..p. raturen at the surface of the soil as high as 157 F.
and no vegetation i what stubble fields tr l:;.!d th-. stabblib and flax-
7eo-dz, '.:.ich -. weeks rf abnormally high trmperatures to endure.

CHINCH BUG (Blissus leucopterus Say)

Ohio. J. S. Houser (August 22): Bye sown as a cover cro- following early po-
tatoes is seriously infested at boosterr. Sudan Erass pasture is dying in
spots from chinch bug dsri e. Several hundred bugs may be found in some
,clusters, and range in age from first-instar nymphs to adults. The fungus
disease Sporotrichum globuliferum is killing many of the insects.

Illinois. L. 1H. Shropshire (August 20): Chinch bugs are very abundant at Des
Plaines and have not been affected by rains so far this month.

Iowa. C. J. Drake (August 2): The infestation has been spreading northward.

Unless weather conditions r-.reat!. Q.: c..the situ.atio-., 60 or more cou"-
tics will be heavily infested with bu 7s in 1935. Losses from the first
-eneration i- 29 con..ties have been estimated, by county a-ents .n, F-'er-
al crop reporters at $9,275",';OC. Fr sail cri::,s e TI.ey estira!te that tho savings from the constructLon of barriers. amounted
to $11,723,000. In the 29' con-ties most heavily infested, the loss to the
corn crop was estimated at 9.35 percent ,and the savings at 35 percent.
r-rs who failed to'Cooperate lost from 25 to 75 pe-rcet of their corn
crop'. '
C r 0,0

Misso ri; L. Hasesan (AukFruast'24): Chinch bu,:;s are in some fields,
b-,t are fewer than expected,'.die, we believe, to the excessively hi,-h
temperatures in July. About ,33-1/3 perce'nt'of the nymphs were still in
the red stace on A u^Jst 10-15, ndO. about 50 p recent of the corn was in
the silo or shock. Recent rains will make food available, in most of
the fields, for byoiun; bhus to mature in-, but we d.o not have as i... ,
now, on ta.h avcra.t, as a year ajo.

ITebrasr a 1. H. Swenk (AuIist 15): :> second brood has been developing
Iaurinc the period fromI July 15 to Au{.'ast 15. In a fe-., inst.n.ces th..
rying tp of the corn throh th- dro-i ht forced a mi,7ation of the
-.Lryl,,,, iip of' the corn th rodtc t'
.n.',"., bu.os of the second brood", and in some instances barriers hal to
be puIt u.p to save feed croos. H. R. Bryson (Au:i st 25): The second brood of chinch bu-. was
very riich reduced, ovwin to the extremely hi-i' te .per'ut-tres that -r,-
vailed .'-rinc July and th: first 15 days in Au u:st, Fiels in the vi-
cinity of Manhattan, where. enou:"h bu"s wvere-presenit to destroy the yrc

CORIT LAI'.. FLY (Pre rinas maidis -.:;)
.T-rth Cerolia. '7. A. mho.ra (Ai: 15): Thiis insect has already put in
its a....r.nce on late corn at Cha,.bourn and has oe so by
feeding :nd 1hepositinL' e....;s in thL: rai. ribs of tho corn leaves. The
e ,xu'i; s.op is attraction; lar 'a nuibers of flies, osps, :." beetles.

New York:. H. H. Ca&pbell and C. Richards (A-u;ast 13): The corn ear wor-
is be';inA .. to appear in I'asfaa County. So far this season this pest
has not been a serious factor, infestation run.iix- fro1- F to 1. percer t.
H. C. !uckett states that, beginning next- week, the second 'brood nay be
expected to cause trouble, resulting in serious infestation.

A. G. West (Auiust 20): The corn ear worm is increasing in Suffolk
County, but is less serious than a year avgo.

Maryland. T. Cory (Auiust 20): The corn ear -worn is moderately abundant.

Virginia. H. G. Walker (August 22): Moderately abundant at orfolk.

North Carolina. W. A. Th:.a. (Augrast 10): This insect is extremely injur-
ious in the Carolinas at this time. Practically all late corn at Cha.d-
bourn, which ranges in height from 1 to 5 feet, is badly riddled. In
some insta-ces the whole bud is filled with frass and all growth is ap-
parently checked. Some of the plants hv died.

Ohio. T. H. Parkls (Aug ust 20): More corn ear worms than usual.

Illinois. L. H. Shropshire (Auegust 20): Corn ear worms abundant in sweet

Minnesota. C. E. Mickel (August 27): The infestation on s',eet corn is 100
percent; on field corn, 90 percent. Worse in the southern third of the

Iowa. C. J. Drake (August 2): The corn ear w.orm is extremely abundant through-
out the State. From 40 to 100 percent of the ears are infer'ted. TI.-- aver-
age infestation will run between 75 and 100 percent of the ears.

C. I7. Ainslie (Augast 22): Utnisual nz.bors of this cor.mion and perennial
pest in the cornfields of northwestern Iowa this In iiany field s
it is almost impossible to find an ear of corn that has not been injured
and. many have been entirely ruined. This is very serious, in view of the
scarcity of feed for livestock.

North Dakota. J. A. Munro (August IS): Corn ear '-,orm very abundant on both
garden and.. field corn.

Missouri. L. Hasen-an (Auguast 24): Very undant in late nubbins that es-
caped the drought.

Nebraska. M. H. Swenk (Aaguast 15): During the perio- from July 15 to 20,
additional reports of d...a.e by the first brood of caterpillars were re-
ceived from the counties east of the 100th meridian, but in greatly dim-
inished nurmbers. Later, during the fourth wGek in July, similar reports
were received. from west of the 100th meridian, as from Wood Lake, Cherry
County; Lewellen, Garden County; .nd Dalton, C.-[.'.:.e County. These
are the first reports that -,e ever have had. of injury in western i'.braska

SOUTH3R1T CORIT STALK BORR (Diatraea craMbidoi,-es Grote)

Vircinia. H. G. Walker and L. D. A. erson (Au-,:t): larm-er corn stalk
borer is v ry a '.'.-, t in y fields near Ti-e'-.-.uer, il-rfolk Cour-ty. Sev-
oral infestations of the lesser corn stalk borer (T1 n ii:.l ; 1T..,:1.s
Zel i. ) hae also b e n ob servcl.

LE._LR CORY STALK BORER (Elasriopalpus lirnosellus Zell.)

Arizo-ia. C. D. LCjert (A;: s;.st 20): The lesser corn. stalk )borer has r-oderate-
ly a....' fro:.. 15 to 20 acres of cor:- in the vici-ity of Sa"fforl. Lar -ae
'cr' tcrke:; from the roots a'J., stalks of corn.

CARSOT ITZ:T. (Liravs .ibbosus DeG.)

Michi an. 1. I. 1lcDaniel (AujTst 9): Adults have been reported as causing
inj ry by feeding on- the roots of elia'this spe cies at .'.A asta, n.-
chrysanthe-nn at Three Rivers. It is also injuring corn an' s--_nflowers.
'. inj -ary is q:-ite extensive, about a dozen beetles bei.. fotid in Fach

MinIInsota. C E. Micel (A 'st 27): bboss is very a,'j-oIdant at oa,
Elk River, and Robbinsdale.

Missoari. L. Hasem-n (August 24): The carrot beetle has been unusually rnric Au'ust, conin;g to li^;ts at ni-h as do June 1beeles in
Jine. They o.'e been feedin7 about the ba.--c.of eeds cultivated.

CODLI1tX MOTH (Oarpocapsa pomonella L.)

New York. W. E. T3lauvelt (August 20): After an apparent rest for a.week
to ten days, the codling moth seems to have come to life again arind is
making fresh entrances each day in Dutchess County, and is causing con-
siderable injury on unsprayed trees in Suffolk County. Not many second-
brood larvae are entering fruits in Clinton County.

E. R. Wi ner (August 27): Stings are ap-oaring in considerable
numbers in badly infested orchards in Orleans County, whnre the first
brood was not controlled.

Maryland. E. YT. Cory (August 20): The third brood (second summer brood)
of the codling moth is moderately abundant in western -.ryl-,nd; numer-
ous in some orchards.

Ohio, T. 4. Parks (August 20): The codling moth is more abundant than
usual and threatens to be serious in a few orchards where it has been
troublesome for several years. In one orchard in Fra_'dlin County,
healthy apples, which had received two cover sprays in June but no
spray for the second generation, becanic quite worm,- early in August.
In most orchards the control is satisfactory.

Missouri. L. Haseman (August 24): IDuring July there vi-, pr-,ctic Kly no
egg laying and up to August 20 no young worms. Iith more moisture
and cooler temperatures, late moths are breeding and we may expect
late worms.

Idaiho. C. Wakeland (August 20): The codling moth is very abundant at
Lewiston end in southwestern Idaho.

Nevada. 3. G. Schweis (August 21): The codling moth is moderately abun-
dant, and app',ren:tly damage is less than last yecr.

A PYRALID (EuBohcr semifunIralis Walk.)

Indiana. L. F. Steiner (August 21): This borer is causing so-e o ^e
to bridge-grafted apple trees in Vinccn-es. As high "s 52 borers were
found on a single trunk, working in new and diseased wood along the
grafts. Adults are emerging and larvae of all irstars seem to be pres-
ent. (Dot. by 0. E. Marshall of iurdue University)

APPLE `LVMA.OT (Rhegoletis pomonella Walsh)

Connecticut. P. Grman (August 23): More apple ma7ots are emerging from
the soil this rear than last, and mrore hovc bc; seen in A-i- t in
apple orchards than usual. The light crop of fruit will doubtless help

- 222 -

produce a heavier infestation than that which occurred lest v.e-r.

LEAFHOPPE'S (Cicadellidao)

Massachusetts. A. I. Bou-rne (August 20)" The young of the late summer
brood of annle leafhoprers are .just beginning to be noticeable. We
shell be able to state more definitely in our next report as to how
injurious this brood will be.

New York. E'. F. Bl-uvelt (August 13): The second brood of the white
apple leafhoTpcr (T-'rhlocyb,' pom-aria McAtee) has bag-n to hatch in
Ulster County. P. J. Chapman believes that the second brood is like-
ly to be fairly heavy in some orchards and will probably cause some
spotting of the fruit.

Maryland. E. N. Cor- (August 20): Apple leafhoppers are extremely num-
erous in western Maryland.

SAN JOSE SCALE (Aspidiotus perniciosus Com-t.)

Georgia. 0. I. Snapp (August 20): Predators and parasites have greatly
reduced the San Jose scale infestation at Fort Valley during the last
2 months; however, we expect an increase during the fall months as

Texas. F. L. Thomas (August 20): The San Jose scale is very abundant on
peaches at Waco.

Idaho. C. Uikelnnd (August 20): The San Jose scale is very atl.a->t at


OFITTAL FRUIT MOTH (Gr'pholith, mol-ta -..-ck)

Connecticut. P. Garman (Au-ast 23): Infestrtion is uneven thr'i,.:hout
the State. Parasites wintered successfully.

Georgia. 0. I. Snapp (Au.7ist 1g): Of 21,1472 Elbcrta pc-.'- os e.y-rrinel at
Fort Valley, only 12, or 0.06 perr.:-t, w,-re fouid to be infested.
Thc!e poaches were harvested from an orchard in which no control meas-
ures a "*inst the moth wo re enforced. As usual, the fruit infestation
was extremely lirht at this point .d the insect is of no economic
imrportance, which is attributed to the absence of a host for the hi-
bemati:..', broods of larvae.

Tennessee. G. I. Bentley (Au--. 20t 20): Serious i.-.jiur in apple orch.-rds
loc-,ted near p-,"-h orchards.

Mississippi. J. M. Lanmston (Au~ast 21): Injury to p t'-.?. tvi.ii by larvae
has recently been or? rvcd -at Hattiesb.r.- in Forrest County, Jackson
in Hinds County, and Stnrkville in Oktibbeha County.


PEACH BORER (Aegeria exitiosa Say)

Georgia. 0. I. Snapp (August 20):' "The infestation is about average in
Fort Valley. Moths have started to emerge in numbers. Tho common
larval parasite Microbracon sanninoideae Gahan is ncw on the wing.

Indiana. J. J. Davis (August 4): The peach tree borer is reported as de-
structive at Angola.

PLUM CURCULIO (Conctr~cIelus nenuphar Hbst.)

Connecticut. W. E. Britton (Aunist 24): The plum curculio is very abun-

Georgia. 0. I. Snapp (Aupust 20): The infestation in the Georgia peach
belt was heavier than average this year, and we are expecting a l-rcr
hibernating population than ,usual. Elbertas were attacked by a fairly
Heavy brood of second-generation larvae. The overwintered adults

North Carolina. W. A. Thomas (August 1): Lima beans in the Chadbourn area
arc very heavily infested. There is h-r5ly a vine that docs not
show swellings made by this insect. Some plants have more than a
dozen of these swollen areas, causing them to break off re-ily when
handled. Borors are much more numerous this season than at any time'
during the past 10 years.

July 15. These reports came from the southeastern p-rt of the Stpte,
from Cedar County southwestward through Blaine County to Chpse County.


SQUASH BU'G (Anasa tristis DeG.)

New Hampshire. L. C. Glover (August 27): The squash bug is abundant through-
out the State. Earlier in the season there wore very few reports of
its beinF present in any numbers. It was thou'--it that the severe

California. J. C. Elrcre (July 351): The pep-er weevil is very abundant
in Oran-Uo County, v; fro". 25 to 95 percent of the pepper crop is
d '--r--,ed. Temperatures higher than normal during the winter, followed
by an early spring, have contributed to this heavy infestation.
Since 1924, there have been 4 years of this tTpe so far as peprer
weevil da-are is concerned. They were 1926, 1928, 1931, and 1934,
all characterized by a lack of low minimum temperatures with su-oer-
normal sprin; terr'erptures. The area was cleonod up of host plants
(peppers and nightshade) during the winter and now has only sli';ht

FALL WEE:''ORM (Hyphantria cunea Drury)

Massachusetts, Maine, New Hampshire, and Vermont. J. V. Schaffner, Jr.

trees are common there and as many rs six nests were found on one
isolated tree. However, no serious defoliation was seen, although the
black walnut trees were most all infested.

NIorth Carolina. W. A. Thom.s (August 1): Farll webworms appeared rt Chad-
bourn somewhat earlier than in normal seasons -nd were fairly abundant
during tho. third weak of June. They are now seldom seen in th'-t area and
did not reach the widespread distribution of last year. The damage has
been much lighter than in former years.

or apple tree in home yards having one, two, or three v.ebs. The-y are
also seen occasionally on cherry :nd locust trees in this section. They
were much more numerous in Clark Cmunty, :.-sh., 'nd nr-ur.,d Prrtland than
in the Sumner-Puysllup section. In addition to th,. trees named above
webs ;,re observed on walnut, m:pl., ash, alder, and prune in the Port-

reports on defoliation for all o: the towns in the infested area this
year have beern received with the exception of a few towns in south rn
.luine and an area in southeastern NMew ,l.': .psh re. Records were made by
State officials but th. information has not been submitted to us. Re-
cord.- for Vermont, Massachusetts, Rhode Isl-.n, and Connecticut are
complete and show no extensive areas of defoliation in Vrz-.ont and

- 233 -

Connecticut but slight increases over last year; a considerable increase
in Rhode Island, totalling somewhere in the.vicinity of 13,000 additional
acres showing from slight to complete defoliation; in Massachusetts about
30,000 acres less defoliation than last year (although in the southeastern
section of this State there was a decided decrease from last year, this
was offset, to some extent, by the heavy increase in more western sections
of th State); in Maine, incomplete records indicate about a 40,000-acre
increase over 'last year; and in New Hampshire incomplete records show an
increase this yeai of over 50,000 acres. For the entire area, to date,
there is nearly a 70,000-acre increase over that reported last year, with
the probability that this will be considerably greater when the records
for Maine and :. Hampshire are complete. In I:--w Jersey 21 male moths
have been taken from assembling cages in sections of Denville, Mendham,
Morris, Pnd Randolph. All of the cages put out by State officials wore
placed in the section where the above towns join, covering Pn 7rea several
miles in diameter froik the point at which the infestation was found last
April. To date 1 male has been taken in Denville; 1 in Mendham; 12 from
one cage, 2 from another, and 1 from another in Morris; and 3 from one
cage and 1 from another in Randolph. In Pennsylvania, 11 male moths have
been taken from assembling cages in the following towns: Blakely, 1;
,Covington, 3 from a single cage; Fairview, 1; Foster, 3 from a single
cage; Franklin (in Luzerne County), 1; Lausanne, 1; and Mauch Chunk, 1.

Maine, J. V. Schaffrer, Jr. (August 24): R. C. Brown reports thrt 21 ad-
ditional townships in Washington, Penobscot, Hancock, and ''-jido Counties
have bezn infested this year. There -as a very high mortality of the
scale where it was not covered by snow or some othur protective covering
during the low temperatures of the ppst winter. low mortality on tre-
trunks near the ground ,nd on some 'of the roots has permitted pcrpetu-tion
of the infestation.
