The Mediterranean fruit fly inspection during the month disclosed
infestations on only seven properties. One of these, at Inverness, Citrus
County, brought in a county in which infestation had not previously been
determined. During the month very few adults or larvae have been found
even within the older centers of infestation.

During the late summer grasshoppers became generally destructive
over the greater part of the East Central, est Central, and Yorth Central
States with rather heavy damage in scattered localities throughout the re-
gion of the Rocky Yountaihs and the Great Basin.

Very heavy losses due to the depredations of wireworms on potatoes
"nd grain have occurred in southwestern Idaho. In one single potato planta-
tion the actual loss caused by reduction in grade due to wdireworm injury
.mounted to $125 per acre.

A serious outbreak of the bertha armyworm, apparently more intense
in the northeastern corner of the State, is reported from the northern
third of !orth Dakota.

A preliminary survey of the Hessian-fly situation in ile'. York indi-
cates that in the important wheat-growing counties the infestation is ex-
tremely light, only about 1.3 per cent of the straws, on an average, being

Tre corn root worm is causing severe lodging of corn in many locali-
ties in the East Central and West Central States.

A report from Georgia indicates that the apple m-..-ot was found for
the first time in that State in August.

The oriental fruit moth is reported as generally serious from
Connecticut southward to Georgia and westward to Illinois and i.'ississippi.
In many parts of this region the percentages of infestation ran very high.
Reports from the Bureau of Entomology's laboratory at :.oorestown, N. J.,
indicated that parasitism in that district was running from 80 to 100 per



The Mexican be.r-n beetle is still being re-orted as generally very
destructive over the entire infested territory.

The banded cucu1-.ber beetle has been found quite numerous at Vista,
Calif., and it -e.nrers to be moving' northv-ar-d in that State.

A --ccies of tussock moth (Hemerocama .eudotsujt .)is defoli-
2ting and killing large are-as of Dou.las fir in the Payette National -Forest
in Idaho.

This season seems to be one of unusual abundance of the ba.-._orm
throu-houit the Middle Atlantic -nd East Central States westward to Kansas.

The fall webworm is decidedly more abundant throughout New Enr -nr,
"e.' York 3t?.te, and Missouri this year.

The pine butterfly is very abund-nt over lvrge areas of the Fyette
!ationril Forest in Idaho, which may indic-te the approach of another cridE-rc,.-

A very serious infestation of the sheep botfly is reported from
Arizona, v:here out of a flock of 9,000 sheep, 1,200 were killed.


Local outbrea-ks of the bertha armry'.orm -have been reported from sec-
tions of southern :.initoba and southern Alberta, chiefly affecting sweet
clover, alfalfa, and flax.

;:-r greasy cutworm occurred in outbreak form in the St. John river
Valley, Nev: Brunswick, affecting a variety of field and garden crops. A
brief survey of potato fields for 30 miles south and 80 miles north of
Fredericton alon, the St. John River Valley showed thnt injury v.-s most com-
mon in the region near Fredericton and was seemningly confined to the broad
valley extending from Oromocto to Zealand.

The -orst infestation in-some years of the c-bb'ze flea beetle is
being experienced all over V-ncouver Island, British Columbia.

Reports indic-te that the whe,-t stem -a,-rot is wides-re-d over the
western 'rilf of Manitobi.

Outbreaks of turnip and cabbge aphids have been reported fro- sec-
tions of New Brunswick, southern Ontario, and the 0k-:na_,-n Valley of
British Columbia.

Larvae of the plum curculio have rarely been more abundant in e.rly
peaches in the tliagara district, Ontario. Th-ey have also been reported as
causing considerable injury to plums locally in the Ga7pere-ux Valley, '-ova

Present indications ere that the oriental peach moth will cruse
serious losses in peach orch-rds of the Niag.ra peninsula, Ontario, partie-
ularly in Niagara :7*nship.

Thegrn-n apple aphid has been present in outbreak form in the Ann-
apolis Valley, Nova Scotia, and the Niagara district, Ontario. It also
has caused considerable injury particularly to young trees in the C k-n'---
Valley, British Columbia. In addition, the black cherry aphid c-used
severe injury to sweet cherries in the Niagara district, and the rosy aple
1phid has been abundant in the eastern Ann-polis Valley, Nova Scotia.

Tussock moths are widespread in the Annapolis V-Iley, Niova Scotia,
and -re causing considerable drm2ge by gn--'ing holes in the fruit in -pple

The fall webworm is present in conspicuous numbers in many sections
of -Tovy Scotia and Ontario and in the Lower Fraser Valley, British Columbia.

7hc apple sucker has been recorded for the first time in the St.
John River Valley, '.- * Brunswick, outbreaks having been discovered in vest-
ern Kings County.

The apple and thorn skeletonizer is widespread in the Annapolis
Valley, 1'cva Scotia, and has also been found in neglected ap-le orchards at
Grimsby and Beamsville in the Niagara Oistrict, Ontnrio.

The outbreak of the hemlock looper on the North Shore of the St.
Lawrence, about 50 miles below the mouth of the Mpnacouagan River, at
Trinity Bay, Quebec, is extending very rapidly and -probably about 1,000,000
cords of balsam spruce pul-p;ood are being destroyed. Other outbreaks of
this species in balsam pulpwood stands are in progress at C-odbout -nd Pen-
tecote on the 4Iorth Shore, and are reported from other valleys along the
coast of the St. Lpvrence River and the gulf of St. Lawrence, extending as
far as Labrador.

An outbreak of a species tentatively determined as the black-headed
tip moth (Peronia variana Fern.) is affecting balsam and spruce over an
areas of Z00 square miles in southern Cape Breton Island, "'ova Scotia. Sev-
enty oer cent of the trees are infested and severe injury is being done
during the present season. This is the first year tha-t this species has
;appe-red in outbreak form.

A very extensive outbreak of the jack-pine sawfly(Heodiprion banksiLna.
Rohver) hcs b-een reported from the Capreol district of northern Ontsrio.

-couting for the gipsy moth in the -rovince of 14uebec this season
has filed so f-r to reveal -ny evidence of the rest.

of ',,ard, IvIcLean, Burleigh, I,.orton, and Golden Valley Coutizi:.

H. H. S',7enk (July, 15-August 1): Grasslroppers continued
active in gardens near Lincoln the latter part of July. In-
jury to alfalfa in =uffalo and Logan Counties was reported
the third week of July.

J. K`cColloch (Ausust 17): Considerable dT.L.. hc. b, en

of grasshoppers increased materially in many sections. This
season parasites are few and grasshoppers are much more abun-
dant. Injury is being done in many parts of Idaho, especi-
ally to small seed crops, and it appears likely that damage
will be heavy and that extensive control measures will have
to be undertaken.

G. G. Schweis (August 20): Very abundant in the eastern
part of the State.

G. F. Knowlton (July 24): Very abundant 3 miles South of

H. J. Pack (July 27):. Very abundant in Tooele County.

M. H. Swenk (July 15-August 1): Melanotus cribulosus Lec.
* as reported in corn roots the last half of July from Richard-
son and Madison Counties.

C. 'Takeland (August 20): Heavy losses have occurred to
potatoes and corn as well as extensive injury to grains and
other crops on which it is more difficult to tabulate losses.
Many cornfields in southwestern Idaho have been planted two
or three times and some of them abandoned, and in many fields
the stand is 50 per cent or less. In a potato field examined
last week, 5 carloads of rurals were dug on 12 acres. Of
these, 1 carload graded U. S. :To. 1, and 4 cars graded :To. 2.
The grower received for the car lo. 1, $600, and for the 4 cars
No. 2, $900. The reduction in grade was due entirely to wire-
worms, a loss of $1,500,or :125 per acre. This is typical of
what is happening in many other instances.

7. W. Baker (August 21): Moderately abundant in Pierce and
Grays Harbor Counties.

E. 0. Zssig (August 21): ..'--derately abundant.

Towner, Cavalier, Pembina, ,7alsh, and Ramsey Counties, and an
isolated outbreak in lgard County. Fields of flax showed
about 15 per cent injury and some sweet-clover fields were
totally destroyed. In 1928 only Rolette and Tow-ner Counties
were seriously infested. It is very dry this season, -hich
is a reverse of last. (August 23): ;;elson, Grand Forks, and
Burke Counties have been addAd to the list in which outbreaks
are found.

pest from July 22 to 29, mppearinw in four different areas in
northeastern Niebraska -nd causing considerable loss to corn
rnd coats. In all cases the worms started with the oats and
wLhen this was strip-od, mijratcd to corn, v:hich was injury.
less severely. In a11 cases the outbreaks occurred on land
that was damagd by hail between June 15 and 25. The parasites
began to control them abcut July 27 and their activities,
with the completion of devoicp:cnt of the voriws, stopped the

New Jersey

P. Garman (Au.rust 24): Reported as attacking peach in New
Haven and Hartford Counties. Increasing in abundance in some
sections and decreasing in others. Macrocentrus sp., Eubadi-
zon sp., and Glyrta rufiscutellaris Cress, have been observed
attacking the larvae.

V;eekly Nevws Letter, N.Y. State College of Agr., August 5 and
19: Injury is severe in some orchards in Niagara County and
is also noticeable in Dutchees and Ulster Counties.

L. 3. Smith (August 2?): The fruit infestation in this

11 '* T

July 13 tq 17.
July 3D to August 7
August 12 to 22
August 21 to 22.

Invisible injury in midseason peaches runs higher than the
visible, being 8 per cent in the Hiley and 9 per cent in the
Elberta. Observations made at the Oriental perch moth labora-
tory indicate that parasitism of the twig-infesting larvae
continues very high as during the past three years, averaging
for the south Jersey peach district, approximately 80 er
cent; 100 per cent parasitism has been obtained- fo-t r'um1erous
midseason collections. Macrocentrus ancylivor ,-L. e-ains
the dominant species. M. delicatus Cress. is LJC ."-o'e abun-
dant than heretofore, and is the second most important species.
'I-t:, rufiscutellaris Cress, is nuch less abundant than last
yerr. The egg parasite Trichoaramma minutum Riley has so far
attained less than 10 per cent parasitism, with an exceedingly
spotty distribution.

South Carolina



C. R.Phipps (August 26): Moderately abundant over the State.

A. I. Bourne (August 22): The plum curculio continues to be
the outstanding problem generally over the State. 7ith few
exceptions, it apoesrs to be fully as serious as in 1928 and
some growers have reported it to be worse. L'any of the -rov.'Lrs
are applying the special 10-day spray.

P. Garman (August 24): The plum curculio has been reported
as attacking apple in New Haven County in greater numbers
than at this time last year.

T. J. Headlee (August I): The plum curculio is moderately

P. D. Sanders (August 23): Has been abundant on the Eastern
Shore until this time.

J.7. J. Schoene (August 26): The outstanding damage during
August was the outbreak in the peach section of Albemarle
County. Many reports were received from the peach sections
of the State during the early months of the suir.Er, but with
the exception of Albemarle County the damage was ended in the
early part of the season. This insect became unusually numer-
ous, causing heavy losses to the peach growers. This is the
only outbreak in Virginia for many years.

Z. P. Metcalf (August): Very abundant over the State.

M.H. Brunson (August 29): Very abundant in various sec-
tions of the State.

0. I. S.,app.(August 16): Many growers are using post-har-
vest applications to reduce the source of infestation for the
next season. Unless a systematic program of control measures
is enforced between now and the harvest of the 1930 peach
crop, another heavy loss is expected. Georgia peach orchards
are now harboring the heaviest population of adults in years.

S. C. Chandler (August 14): There has been much late injury
in peaches in southern Illinois, running as high as 20 per




cent in some spravrfd orchards. Jarring records in sptra:'ed
and unsprayed orc.,ards showed the maximum number of curcJlios
July 29, about one week before the start of the Elberta har-
vest. Just as the harvest started a-big dror. took place in
the number. This '.ts taken plkce every year since jarring
records have been -ade in the State.

SOUTHERN PINE BEETLE (Dendroctonus frontalis Zimnm.)

R. A. St. George (August 5): This insect attacked second-
rrov:'th shortleaf pines near the Bent Creek labor-tcrv of the
Pisgvh intional Forest, the first week of July. .recs from
2'} to 15 inches thick and from 20 to 40 feet high were at-
tacked. This infestation seems to show correlation between
abundance of beetles rnd weather conditions. A heavy brood
overwintered and a big spring emergence was anticipated, but
excess of rainfall from February to Msy c-:usEd he-vy mortality
by drowning the beetles in the glleries. During June and
enrly July the rainfall was redu-ced to normal followed by a
deficiency in late July, which possibly caused the above :t-
tack. Dyinz pines have been retorted in several States in
the southeastern and southern sections during July. Hymen-
opterous parasites have been very abundant ovirositinc- in
the beetle lrvae and this will result in their death vhen
the r-rasite-*lrvae mature.
