THE MORE IMPORTANT RECORDS FOR SEPTEMBER" ii
At the last of September grasshoppers were still doing damage from
Illinois to southern Minnesota and southward to Missouri and' Oklahoma-. They
also continued to he destructive in the Great Basin. Over much of the in-
fested territory egg laying was well under way.
Scattering reports of damage by wireworms were received from Pennsyl-
vania, North Dakota, and Washington.
During the month outbreaks of the garden webworm occurred in Indiana
and Michigan. The principal damage was to alfalfa.
Hessian fly is abundant in volunteer wheat in parts of Ohio, Wisconsin,
North Dakota, and eastern Missouri.
Infestation by the European corn borer in 10 counties in Wisconsin was
found during the summer. The. insect is building up heavy populations in
western Pennsylvania.
Heavy damage to small grain and alfalfa seed by Say's stinkbug was re-
ported from Utah and Arizona.
Late in summer a large codling moth population developed from northern
Ohio to northeastern Kansas.
The flatheaded apple tree borer was seriously damaging apple trees from
Indiana and Nebraska southward to Oklahoma and Missouri.
The oriental fruit moth was more abundant in Ohio than it has been for
several years. It was also reported as abundant in Connecticut and as doing
some damage in Georgia and Mississippi.
Heavy infestations of the grape leafhopper were reported from Kern
County; Calif., and of the grape leaf folder from the San' Joaquin Valley.
- 385-
- 3S6 -
The walnut caterpillar was reported in destructive numbers from Virginia
to Elorida and westward to Wisconsin "and Oklahoma. • • ■
. The Mexican "bean "beetle "became abundant in extreme northwestern New
York, in Virginia, Ohio, and Indiana, also in 'the Gulf region.
The harlequin "bug is "building up heavy populations in southeastern ,
Virginia.
The corn ear worm was reported as causing commercial damage to peanuts
in Oklahoma. This is the first report of serious damage "by this insect to
this crop in Oklahoma.
The worst infestation of tobacco "by hornworms ever reported from Mary-
land occurred this year. Damage was most serious in southern Maryland, where
entire fields were stripped "before harvest, and severe damage was later done
in the tobacco barn.
Infestation by the pink bollworm in the Big Bend area of Texas was
heavier and earlier this year than last.
Late in the season considerable defoliation and ragging of cotton "oj
the cotton leaf worm occurred over much of the Cotton Belt.
The bollworm was quite generally prevalent .from Georgia to Texas, al-
though upland cotton was practically made before worms became very numerous.
Serious damage, however, occurred in parts of Texas.
The locust leaf miner occurred in outbreak numbers in Virginia aid
North Carolina.
The larch sawfly is at a very low ebb in the Lake States.
The European spruce sawfly has increased to alarming numbers through-
out the northern part of the New England States. . . • . .'.'...
Severe damage to lawns by the hairy chinch bug was, reported from New
York, Connecticut, Ehode Island, and Ohio.
An unusual number of reports from the northeastern fourth of the
United States indicates an outbreak of fleas.

THE MORE IMPORTANT ENTOMOLOGICAL FEATURES IN CANADA
FOR AUGUST And SEPTEMBER
The light and patchy grasshopper outbreak in southwestern Manitoba
was greatly aggravated late in July and early in August: by extensive flights
of grasshoppers fron the southeast, with the result that much head damage
was done to late crops and prospects of a severe outbreak in 1938 were con-
siderably increased. In Saskatchewan heavy migrations of grasshoppers in
southern areas and their concentrations on late crops elsewhere continued to
reduce feed supplies. Preliminary surveys revealed important infestations
practically throughout the agricultural area. While these were light in
many newly infested areas, 'the area of severe outbreak had also spread
markedly, especially in the northwest. Exceptionally -severe and general
outbreaks are indicated in the Province for next spring. Severe damage and
crop loss occurred in. some localities in southern Alberta. Although 1937
was a peak year for grasshopper abundance in the interior of British Columbia,
crop losses were small as a result of control efforts.
Moderate' infestations of the Mormon cricket were reported in several
localities in 'Manitoba and Alberta. ,
Outbreaks of the arnyworra occurred in parts of eastern Canada and the
Prairie Provinces: The outbreak in Nova Scotia and Prince Edward Island; was
the worst in nearly two decades. Moderate- to- light infestations developed in
New Brunswick and southwestern Ontario. With the exception1 of the southwestern
municipalities and a strip eastward along the international boundary as far as
Manitoba, practically the whole agricultural area of Manitoba suffered heavy
infestations. Outbreaks of different degrees of severity also occurred in
Saskatchewan. .-.:.:-.••■
Extensive damage to field and garden crops by second-year white grubs
occurred over a wide area in southern Quebec.
Considerable loss of wheat from the attacks of the wheat stem sawfly
was reported in the prairie sections of Saskatchewan wherever crops matured.
Losses in Alberta this season were more extensive nnd severe than in 193&*
A gradual resurgence of the hessian fly population is occurring in
southern Ontario, owing to the practice of early seeding.
Say's stinkbug is quite abundant in Alberta and occurs over- a wide
area in this Province and Saskatchewan. The area extends from the inter-
national boundary, west to Cardston, Alberta, east to East Poplar, Saskatch-
ewan, nnd north to Calgary,' Alberta, m d Alflask and Ardath, Saskatchewan.
An outbreak of the beet webworm of probably unprecedented severity and
-3SS-
widespread distribution developed in Saskatchewan and increased the seri-
ousness of the feed situation in drought areas by destroying weed growth
otherwise available -for feed. . Outbreaks also occurred in southern Alberta.
Field beans in southern Ontario' were infested with "the green clover
worm,, but not to an extent to cause stripping of the plants.
.:■■.■-, A;. general decrease in the abundance of the European earwig in in-
fested areas in British Columbia was 'reported/. Imported parasites of the
earwigs have been. widely distributed in these sections in 'recent years.
Injury to apples by the: first :hrDod of codling moth was reported
to be unusually severe in the Niagara district, the Georgian Bay district,
and eastern Ontario.. .-.■■:,.■;■
Aphids affecting orchard trees have nowhere "been reported in out-;
break form. The apple aphid and the rosy apple aphid were [noted as of '
minor importance this year in-' the Niagara district, ... .'-.'' "„.^.
Outbreaks of the apple arid thorn skeletonizer, apparently local-
ized, occurred in parts of northern Nova Scotia and Ontario.
The infestation of second-brood oriental fruit moth was' low in
the Niagara district. An average twig infestation of 3»^ percent was
reworded in young peach orchards. The infestation in southwestern
Ontario was higher than in 193^ •
The pear leaf blister mite is "more prevalent than usual, particu-
larly on young .pear trees'/ in parts of southern Ontario. A local severe
outbreak occurred in New Brunswick. ' ■■"•:.
A distinct increase in numbers in the first generation of the
European spruce .sawfly was general in New Brunswick, and in the centre
of the Province large areas were beginning- to show defoliation. In
Quebec new severe attacks on spruce occurred. in Bonaventure County, and
; heavy samples, of . larvae were received from Karaouraska and Montmagny
Counties. West of the St. Lawrence River the sawfly is now known to ex-
tend from Lake Saint John westward to Lake Temiskaming.
The black-headed budworm is evenly distributed and fairly ahundant
from Saskatchewan to the Gaspe, with local concentrations in northern
Algoma.
Increased infestation and damage to balsam fir by the. "balsam woolly
aphid has developed in the Maritime Provinces.
The larch sawfly has increased. in numbers in parts of Nova Scotia
and New Brunswick. An infestation was discovered south of r,Silverton,:-
British Columbia, 62 miles farther west than previously recorded.

GENERAL FEEDERS'.
GRASSHOPPERS (Acrididae)
Illinois. W. P. Flint (September 20,): In moat sections of the State there
has been a marked decrease in the numbers of grasshoppers from August
20 to September 20. ' Some sections still have moderately heavy infesta-
tions. Egg laying is'now. in full progress, with the weather ideal for
the deposition of eggs.
Wisconsin. E. L. Chambers (September 20):. Practically every county reported ^
• serious damage to certain crops — alfalfa, tobacco, orchard, and garden;
and 52 out of 71 counties spread more than 10,500 tons of bait. Serious
damage is still being reported.
Minnesota. A. G. Rugglos and assistants (September): Grasshoppers are abun-
dant in the southern third of the State.
Iowa. H. E. Jaques (September 2U): Grasshoppers are still very abundant
throughout much of Iowa, but their present damage, with the exception of
garden and some other fall crops, has been quite negligible. We have
recently taken a number of specimens of Schistocerca line at a Scudd. in
Henry County. This is a new record for this species in the eastern half
of the State.
Missouri. L. Haseman (September 23) * During September grasshoppers have
continued to attract attention; in fact, with the scarcity of rain over
most of the State and the shortage of wild vegetation, they have tended
to move onto late corn, fruit trees, and garden crops, more perhaps than
earlier in the summer. Through central Missouri, Melanopluss mexicanus
Sauss. is now by far the most abundant and active species. The second
brood is maturing, mating, and laying eggs at this time. M. differ-
entials Thos. is present in numbers around the edges of cornfields and
other tall vegetation, and likewise is mating and ovipositing. Since
about the first of September very few of the two-lined grasshoppers
(M. bivittatus Say) have been observed. Unusual numbers, of the Carolina
locust (Dissosteira Carolina L.) have been collecting in bare places,
being more abundant than I have seen them any time during the past,
several years. Our common red-legged grasshopper (M. femur-rubrum Deg. )
in central Missouri, appears with M. mexicanus at the rate of about 1 to
10 of mexicanus.
Kansas. H. R. Bryson (September 25): Grasshoppers are still quite abundant
and are a threat to the early sown wheat. Alfalfa fields in localities
of very low rainfall have been considerably injured. Egg deposition is
.taking place at a rapid rate.
Nebraska. M. H. Swenk (September 22): While the corn crop has passed the stage
where grasshoppers may damage it seriously, damage has been rather .heavy
to late summer seedings of alfalfa .and the early seedings of winter wheat
and rye. Over 1,000 tons of bait materials have been used in the last 30
-390-
days. Use of bait has "been particularly heavy in the southwestern and
western third of the State, although large quantities have "been used
throughout, the entire winter wheat-growing section.
Oklahoma. C. E, Stiles (September IS): Grasshoppers are congregating in
most places and depositing eggs. However, on the west side of the State
they are doing serious damage to fall-planted wheat. Alfalfa is also
being seriously damaged in some of the. central counties. Considerable
poisoning' is being done in the western counties. The species most common
are M. different ialis and M. mexicanus.
Utah. C. J. Sorenson (September 20): M. femur-rub rum is very abundant in
Millard, Cache, and Box Elder Counties. M. packardii Scudd. is very abun-
dant in Sanpete, Cache,, Juab, and Millard Counties. M« biyittatus is very
abundant in Sanpete, and M. mexicanus in Tooele, Millard, and Juab Counties.
Camnula pellucida Scudd. is very abundant in Tooele County,
«
G. F. Knowlton (September 10): Grasshoppers are more abundant in
most parts of Cache County than they have been for several years. They
are damaging alfalfa seriously in North Earmington, east of Lay ton, -and
southwest of Salt Lake City, in northern Utah. Eight hundred acres of
alfalfa and several thousand acres of range land were heavily infested
on ranches along Indian Creek, in San Juan County.
WIREW0RM5 (Elateridae)
Pennsylvania. M, D. Leonard (September 22): Reported to have been very -in-
jurious to various vegetable crops, especially tomatoes," in Chester County
this summer.
North Dakota. J. A. Munro (September 17) I A survey has been conducted in
potato fields in Traill, Grand Forks, Walsh, and Pembina. Co\mties. Some
fields show only a small percentage of the tubers injured, while others
in nearby areas show injury as high as 6S percent. The most serious in-
festations have been found in the Hopple and Crystal vicinities of Walsh
and Pembina Counties, The predominating species appears to be Ludius
aereipennis Kby.
Washington. E. W. Jones (September 23) ' Linonius canus Lee, was found to be
damaging fall spinach and lettuce early in September at Walla Walla.
JAPANESE BEETLE (Po-oillia japonica Newm. )
Connecticut. W. E. Britton (September 23): Several cases of rather severe
grub injury to lawns have come to our attention. Heretofore most of the
damage has been caused by the adults to foliage and flowers. Adults have
been received for identification from Greenwich, New Haven, and Woodmont,
and several lots of larvae from New Haven.
New Jersey. C. H. Hadley (August): Heretofore feeding by beetles on the fruit
of grapes has not been observed, and it was thought that such feeding did
not occur. However, on August 13, extensive feeding by beetles on bunches
of grapes was observed in a vineyard at Holmdel.
-391- -
ASIATIC GARDEN BEETLE (Autdscrica castanca Arrow) -■'. .
Connecticut. W. E. Britton (September 23): Grubs are now injuring lawns,
often in association with those of Ano.mala oriental is Wtrh. and P.
japonica, particularly in the New Haven region.
ORIENTAL BEETLE (Anomala orientalis Wtrh.)
Connecticut. W. E. Britton (September 23): The grubs of this insect continue
to damage. untreated lawns in New Haven and West Haven. Many separate lots
of grubs have been received for identification and information regarding
treatment.
WHITE- FRINGED BEETLE (Naupactus leucoloma Boh.)
Alabama. J. M. Robinson (September 19'): Adults are still depositing eggs in
the infested area in Covington and Geneva Counties. Some have deposited
as many as l.UOO eggs.
PULLER'S ROSE BEETLE (Pantomorus godmani Crotch)
Georgia. T. L. Bissell (September 17): This weevil is abundant, possibly
abnormally so, feeding on Lespedeza bicolor, soybeans, and coffee weed
at Experiment.
A TENE3RI0NID (Pelecyphorus densicollis Horn)
Washington. M. H. Hatch (September 22): Enormous numbers of adults were seen
swarming in the sagebrush just east of Prosser on September 20. At time's
in the past this species has been so abundant as to clog irrigation ditches
between Prosser. and Kennewick.
A FALSE WIREWORM (Eleodes sp. )
Kansas. H. R, Bryson (September 2b): The false wireworm has been reported
causing considerable injury to wheat in Kansas, as far east as Saline.
Deficient rainfall in the wheat district and much early sown wheat are
contributing to the amount of injury.
ARMYWORM (Cirphis unipuncta Haw.)
Maine. H. 3. Peirson (September lU): A large flight of moths occurred at
Bar Harbor August 25.
Rhode Island. A. E. Stene (September 21): Late in August we had an outbreak
of armyworms in Providence- County, more severe than the earlier ones in
Kent and Washington Counties. A large millet field was destroyed, and
the caterpillars marched to an adjoining field which fortunately was an
old pasture where they found little food. Here also parasitic flies were
abundant and hardly a caterpillar could be found without from 1 t^ 10 or
even 15 eggs attached.
Oklahoma. F. A. Fenton (September 20): Armyworms and several species of
cutworms are uriu dually numerous arid are cutting dp withe young wheat
plants in many fields.
.••■'. ■■-••■'■■■•■ .WHITE-LINED SPHINX (S-ohinx line at a F.)''
Maine. H. 3. Peirson (August): This moth has "been seen abundantly this year
hovering over flowers in gardens^ .. in. .cehtral' arid southern Maine. Numerous
inquiries have also been received concerning it from various places in
the State, it being often mistaken for' a' hummingbird. ■••■'• t'
Michigan. R, Hut soil (September 20): Has boon re-ported from all over the State.
Iowa. H. E. Jaques (September 2*0; Has been very abundant in both the larval
and adult stages throughout the State'.- ■■ -The larvae in many cases are
feeding on purslane and other weeds, so that their presence has not
■■■■'■ ' created a serious problem. - '■■'• ' ■ •
CEREAL AND FORAGE-CROP' INSECTS
. /-,::'■ WHEAT
HESSIAN FLY (Phytophaga destructor Say) •- ■•
Ohio. T. H. Parks (September): While the infestation in the 1937 wheat crop
was very light,, eggs are now abundant on volunteer wheat in some counties
showing a very low infestation in July.
Wisconsin./ E. L. Chambers (September '20'): Once so abundant that it resulted
. "in .the abo'ndbnin'g of winter wheat raising in the State, the hessian fly
is making its appearance on grain after many years' absence. Eggs and
larvae observed on volunteer grain in 'Lane and Jefferson Counties.
North Dakota. J. A. Munro (August 6): Specimens collected on one of the
Station plots at Fargo. Some of the plots are infested as high as 50
'percent — Hope: Reward cross. (September 17): An examination' of most of
' the varietal wheat plantings on the station grounds brought the average
infestation rather low, about U percent.
Missouri. L. Haseman (September 23): Summer and fall stubble surveys indicate
a scarcity of live flaxseeds over a considerable part of Missouri. How-
ever, throughout the northeastern and most of the eastern and southeastern
parts' of the State they are present in sufficient numbers to cause worry,
where growers found conditions favorable for seeding early. Over most of
the State, however, scarcity of rainfall is holding back seeding or, at
■least, wheat sprouting, so that it now appears that comparatively little
wheat in this State will be up and exposed to flies even where they are
■'■'- -'abundant'/ enough to cause worry. ■ ' ■■ ■-■
Kansas. H. R. Bryson (September- 25) : Hessian fly is not depositing eggs at
this writing.
-393--
CHINCH BUG (Blissus leucopterus Say)
Illinois, f. P. Flint (September ,20): Very spotted and moderately heavy in-
festations of chinch bugs exist in many small areas in the south-central
and southern parts of the State. The latter part of August and fir^t of
September have been very dry, and while these insects appeared late in
the season they are in most cases developed sufficiently to enable them
to hibernate in the ad\ilt stage.
Kansas. K, R. Bryson (September 25): Chinch bugs are present in considerable
. numbers in sorghum fields but are doing no damage.
APPLE GRAIN APHID (Rhopalosrohum prunifoliae Fitch)
Nebraska. M. H.. Swenk (September 22-): Whent plants in Frontier County are
being killed out by the apple grain aphid.
Correction — In the Insect Pest Survey Bulletin Vol. 17, September 1, 1937. No,
7, page 3^2, regarding the sawfly in Ohio, by E. J. Udine, the heading
should read Black Grain Stern Sawfly (Trachelus tabidus F. ) , instead of
European Wheat Stem Sawfly ( Cephas py gmae us L.)
CORN
CORN EAR WORM (Keliothis ob so let a F. )
Pennsylvania. M. D. Leonard (September 22): C. A. Thomas reports that corn
• 'f ear worm was scarce in eastern Pennsylvania this season.
Illinois. W. P. Flint (September 20): A heavy infestation developed late,
building up to a maximum during September.
Wisconsin. E. L. Chambers (September 20): ,-Has been r-;aorted doing damage to
chrysanthemums in several commercial florist establishments in Milwaukee.
Tennessee. L. B. Scott (September 3) ' Very abundant in central Tennessee.
Damage has been severe in corn and tomatoes, but probably more severe in
corn.
Kansas. H. R. Bryson (September 25): Abundant in sorghum heads.
Utah. G. F. Knowlton (September 6): Infestation was heavy in corn, but to date
rather light in tomatoes at Castle Dale and Huntington.. Cor. i ear worms
have damaged most of the swuet corn at Duchesne and Price, and 10 percent
of the tomatoes were damaged in one field examined at Price.
EUROPEAN CORN BORER (Pyrausta nubilalis Hbn. )
Connecticut. N. Turner (September 20): Late sweet corn ,-t the Mt. Carmel Farm
-39^-
was unusually heavily infested, about go percent of the cars "being
attacked. We have several reports of similar damage in southern
Connecticut. Unsprayed dahlias were also heavily infested, dissections
showing as many as. 73 "borers in a single plant. Many second- instar
larvae are present and p. few cast pupal skins, indicating that, there
may be a partial third generation this year. Injury to gladiolus. has
been reported, and larvae in stalks received from Westport.
Pennsylvania. R. M. Baker (September): The infestation in Erie and Crawford
Counties has been building up until, on a recent survey, 30 percent of
the cornstalks in some fields were found to be infested. The infesta-
tions in Centre, Clinton, and Lycoming Counties arc showing only a very
slight increase.
Wisconsin. E. L. Chambers (September 20): More than 60 fields" of "corn were
found infested in 10 counties bordering on Lake Michigan.
CORN R00TW0RM ( Dia.br ot lea longicornis Say)
Connecticut. W. E. Britton (September 2l): Adults damaged' corn by- shredding
the husks and eating the kernels at Lakeville. Twelve were submitted for
identification. , ... . .
ALFALFA
GARDEN WEBWORM (Loxostege similalis Guen. )
Indiana. J. J. Davis (September 2S): More abundant and destructive to
alfalfa than f"or- a number of years, destroying a large acreage of this
year's sowing of alfalfa in the northern two tiers of counties. The
first report came from Lagrange County, August 26, and by 'September 2
the webworms had eaten three-fourths of all the new alfalfa seeding in
the county. Reports continued through the month of September, most of
them coming in early September.
Michigan, P.. Hut.son (September 20): The garden webworm is destroying alfalfa
;seedings in southern Michigan.
Oklahoma. C. E. Stiles (September IS): Has completely defoliated many of
..the alfalfa fields throughout the central part of the 'State. Cotton in
some instances has also been damaged and where food has been scarce, this
pest has fed 'on a variety of plants. This is one of the worst outbreaks
that has ever been observed in Oklahoma.
ALFALFA CATERPILLAR (Eurymus eurytheme Bdv. )
California. C. S. Morley (September. 3) : The butterflies were very numerous
and in the Kern Lake, district larvae injured half-grown alfalfa to the
extent that several hundred acres bad to be cut before maturity in order
to stop the invasion.
-395-
ALFALFA WEEVIL (Hypera postica Oyll.)
Utah. C. J. Sorenson (September 20): .Alfalfa weevil very abundant in Piute
County. Serious damage in 1937*
California. A. E. Michelbacher (September 20): Larval and adult populations
continue to be very small. In the San Joaquin Valley on September 17 a
few individuals were collected in two fields, while in the San Francisco
Bay area a few were taken in a single field.
GRAPE COLASPIS (Colaspis brunnea F. )
Arizona. H. F. Tate (September 20): There has been a serious outbreak of this
beetle on seed alfalfa this fall. There are 10,000-12,000 acres of seed
alfalfa in Yuma County.
. SAY'S STINKBUG (Chlorochroa sayi Stal)
Utah. C. J. Sorenson (September 20): Severe damage; 50 percent- to barley and
considerable damage to first-crop alfalfa seed in New Castle, Iron County,
and in Millard County. • Moderately abundant to very abundant. In Wash-
ington County, moderately abundant, with damage to sugar-beet seed.
Arizona. C. D. Lebert (September 2): Inspector Mendcnhall reports 30 to 35
percent injury to seed alfalfa from C. sayi and riant bug, Lygus sp. ,
injury in the Gila Valley and near Safford.
TARNISHED PLANT BUG (Lygus pratensis L.)
Arizona. K. F. Tate (September 20): There has been a serious outbreak of
the tarnished plant bug on seed alfalfa this fall.
POTATO LEAFHOPPER (Enrooasca fabae Harr. )
Kentucky. W. A. Price (September 2U): Severe leafhopper injury to alfalfa
in the northern section of the State.
CLOVER
GREEN CLOVER WORM (Plathypena scabra F. )
Ohio. N. F. Howard (September 20): At Columbus during the early part of
August green clover worm was rather scarce, but in September it 'was found
to be quite numerous, although not as abundant as some years.
-396-
FRUIT INSECTS... •-
APPLE
CODLING MOTH (Carpocapsa porno ne 11a L. )
Ohio. T. H. Parks (September): Codling moth developed into a problem princi-
pally in. Lawrence County on the Ohio River ', .and in Lucas and Ottawa Counties
•. : in : northern Ohio. ■ The month of August was. dry, and bait-pan catches at
'■'Columbus and Toledo showed increased moth activity "between August 10 and
■ 20. This was followed by* injurious entrances after the middle of August.
Orchards checked in central and eastern Ohio show very low infestation.
Michigan. R. Hutson (September 20): The second brood was not .so severe as
was expected. . • „■•• ■
Missouri. L. Haseman (September 23) ' During September there has been a steady
emergence of third-brood moths with. an unusually sharp pickup in abundance
in northwestern Missouri during the last few days' of August. •
Missouri and Kansas, H. Baker (August 3l)J The second brood appears to have
caused more damage in northwestern Missouri and northeastern Kansas than
any other one brood since the spring brood of 193^» Well sprayed .orchards
show many stings and poorly sprayed, ones are very wormy. Greatly increased
bait- traps catches of moths which hegan August 27 » indicate that third-
brood damage may be heavy if weather conditions are favorable.
YELLOW-NECKED CATERPILLAR ( Pat ana ministra Drury)
Missouri. L. Haseman (September 23) • A second, generation appeared in Se;ptember.
The larvae are now largely full fed and where the foliage of apple has not
had a good spray coverage a good deal of damage to the foliage has been done,
APPLE LSAPHOPPERS (Cicadellidae)
Massachusetts. M. D. Leonard (September 22): Leafhoppers, Tyohlocyba aomaria
McAtee , are very injurious in at least- one large orchard in the State a.n&
presumably abundant in others, according to an authentic report received
during August.
Connecticut. P. Garman (September 21): Infestation by the white -apple leaf-
hopper (T, pomaria) is irregular;" some orchards. heavily infested, others
not at all.
Virginia. A. M. Woodside (September 20): The white apple leafhonper is present
in large numbers in many orchards of Augusta. County, but no severe infesta-
tions have been observed.
Missouri. L. Haseman (September 23): During September the various species of
leafhoppers on apple have been unusually abundant and injurious to the
fnliage. There seems to have been a rapid increase of leafhoppers during
-397-
the last few weeks. This, combined with the scarcity of rain, caused
considerable drop of the Jonathan apples early in September, though during
the middle and latter part of September Where Jonathans were not picked,
the dropping of the fruit largely stopped..
FLATHEALED APPLE TREE 3 OEM (Chrysobothris femorata Oliv. )
Indiana. J. J. Davis (September 25) '• Continues to be reported from many parts
of the State damaging apple and maple.
Missouri. L. Hascman .(September 23): Although adults were more abundant earlier
in the summer than we have ever seen them in Missouri, there is really less
damage showing up during September than occurred during the past" two' or
three falls.' Unfortunately, there are plenty of the borers in weakened
trees and developing on limbs and exposed trunks in healthy trees, but far
less than we expected.
Nebraska. M. • H* Swenk (September 22): Complaints of damage to fruit and' shade
trees, principally ash, elm, willow, and flowering crab apple, were re-
ceived from August 20 to September 22 from several counties.
Oklahoma. F, A. Fenton (September 20): Continues to be the most important
tree-boring insect on shade trees. Reports arc being received from widely
scattered parts of' the State.
ROUNLHEADED APPLE TREE BORER (Saperda Candida 'F. )
Missouri. L. Hasemar. (September 23): At Columbia the young larvae hatched
during August and by early September most of them were through the outer
bark feeding on the .cambium. By the middle of September, many of these
had developed tunnels 2 and 3 inches in length, and the grubs were over
|r inch long. In some orchards they have been unusually abundant,' and ;
where not remove.d promptly seriously damaged both young and bearing trees.
PEACH
.PLUM CURCULIO (Conotrachelus nenuphar Hbst.)
Georgia. 0. I. Snaop (September U) : Jarring records showed a considerable
increase in adult curculios in peach orchards at Fort Valley, central
Georgia, early in September. An average of 1.5 beetles per tree were
taken by jarring on September U. This is more than at any time since
April 3» when adults were appearing from hibernation. Weather conditions
have been favorable for the development of the second generation, and
the sudden increase of adults in peach orchards is believed to be due
largely to the recent emergence of second-generation adults from the soil*
Many of the beetles caught on September U were clean and looked to be new
individuals. Seventy percent of the first-generation females deposited
second-generation eggs, which is more than usual.
Nebraska. M. H. Swenk (September 22): Reported attacking plums in Sheridan
County, September 6.
-398-
ORIENTAL FRUIT MOTH (Grapholitha moles ta Busck)
Connecticut. P. Gar man (September 21.)': Infestation in fruit varies from
■ - 10 percent or less to 50 percent.
Georgia. 0. I. Snapp (September 9): Attacked flowering peach trees- planted
on street's of Port Valley. Many-terminals of these trees have been damaged.
Ohio.' T; H. Parks (September): More' abundant than for several years. 'The
Elberta peach crop was infested" in varying degrees, 1 bushel analyzed at

GRAPE LEAFHOPPER (Brythroneura comes Say)
Missouri, L. Haseman (September 23) ' During the last days of August and
, .; throughout September, leafhoppcrs on grapes increased greatly in numbers
in central Missouri and leaves on the more susceptible varieties were
badly spotted by feeding. Late sprays, however, largely eliminated the
brood of immature hoppers.

-399-
the leaves on most Virginia creepers, observed recently in northern Utah.
Certain varieties of grapes have boon similarly damaged.

Missouri. L. Haseman (September 23) J; Throughout practically the entire State
the second-generation larvae ate the foliage from walnut, hickory, and
pecan trees. Early in September larvae forced to migrate in search of food
in central Missouri fairly carpeted the ground' around walnut trees that were
stripped. Many medium-sized trees had from 15 to rjQ> colonies of these worms
feeding -on them.' This insect has been serious in recent years but never
has it done the. damage that it did' this fall. The season is late enough
so that no serious injury will be done to the trees. In many places the
larvae wore so abundant that most of the later colonies died of starvation,
though great numbers have gone into winter quarters.
Oklahoma,. C. F. Stiles (September 18): The second brood has defoliated a large
percentage of the pecan and walnut trees throughout the State. This is the
second time that these trees have been "defoliated this season. The growers
are considerably, worried about- the future of ' the pecan industry as many of
the trees are weakened and will die during: the coming year.

of the green bolls were infested, with an estimated lo.rv.al population of
212,000 per acre, as compared with 37-Percent boll infestation and 6^,000
larvae per .acre in 193&. During the week ended September 18, 1937 > in the
19 fields examined the average .percentage of green bo lis infested increased
to 97 percent, with, 8.8 Larvae per infested boll, in comparison with 90-
percent boll infestation and 5»9 larvae per ."boll last year. However, the
crop was also much further advancer and was maturing considerably earlier
than last year, as shown by an average of 2.6 green bolls per plant in
1937 and 5*9 green bolls per plant in 193&, and the damage is not expected
to be any greater. than last year, despite the high infestation. (September
25): A total of 1,497 boles, had been ginned up to September 24, as com-
pared, with 601 boles on the same date last year. Infestation counts made

inches .across were found at the joints of the legs. Even on the backs
of some animals areas were depilated and encrusted, or even raw. Many
farmers confined their horses in darkened barns' during the day. Work
animals were handled with difficulty, notwithstanding partial protection
afforded by nets and burlap* Man, too, was subject to their vicious
attacks and found them as annoying and persistent as mosquitoes. On

them extremely annoying, when the hands were occupied in making adjust-
-U27-
ments. The flies were less evident and sometimes entirely inactive during
the noon-day heat when the temperature approached or passed 100° F. On
several days the shaded side of a stock tank was covered with stableflies
at the rate of from 100 to 200 per square foot, no doubt attracted "by the
cooling effect of the water within the tank. A considerable reduction in
