OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JUNE, 1923.
The past month has been one of unusual insect abundance throughout the
greater part of the country.
Cutworms of several species attacking practically all field: and truck crops
have been reported from the entire northern part of the country, reports of serious
injury coming from Massachusetts, New York, Michigan, Iowa, South Dakota, and Idaho,
and unusual wireworm injury to both cereals and truck has been reported from Ohio,
Indiana, and Illinois in the East-Central States, and from Montana, Idaho, and
Washington in the Northwest.
Serious grasshopper outbreaks have been very general over the upper
Mississippi Valley, through the Rocky Mountain region, and along the Pacific Coast.
Reports cf outbreaks have been received from Wisconsin, North Dakota, Nebraska,
Kansas, Texas, Wyoming, Utah, Oregon, and northern California. In the Klamath Lake
region of California poisoned bran bait was being distributed at the rate of 10,000
pounds daily.
Heavy flights of June beetles occurred in parts of New York, Illinois,
Wisconsin, and South Dakota; on Long Island, and in parts of southeastern South
Dakota the heaviest flights that have been observed in years were recorded this year.
By the middle of the month the chinch bug was migrating from small grain to
corn in Indiana. The situation relative to this insect, however, looks much more
favorable than earlier in the season over the greater part of the chinch bug region.
Egg laying was generally delayed by the backward season and heavy rains associated
with the fungus disease and egg parasite in Illinois, Nebraska, Kansas, and South
Dakota have materially reduced the infestations .
Hessian fly injury will be severe in Iowa and Nebraska owing to the heavy
spring brood of flies and wheat is damaged from 2 to 25 per cent in parts of Illinois
and Missouri by the jointworm. In some fields in Greene County, Missouri, 12 per
cent of the straw is down owing to the feeding of the latter pest.
The boll weevil is emerging in fairly large numbers throughout the Cotton
Beltj indications have already been reported of heavy broods in Georgia and Texas.
A suggestion is made that dusting for the boll weevil tends to increase damage by
cotton aphids by killing lady-beetles which feed upon this pest.
The pale striped flea-beetle is doing unusual damage to corn and truck crops,
particularly to beans, in Indiana, Illinois, and Virginia.
The seed-corn maggot is again appearing in unusual numbers in parts of New
York, Illinois, and Tennessee. In the last State the outbreak was decidedly more
serious on land where fresh tankage fertilizer had been used. A similar association
of this pest with organic fertilizers was noted in 1921, when an unusual outbreak of
this pest occurred along the Atlantic Coast.
- 106 -
The rosy apple aphid was reported as unusually abundant in central New York,
southern Pennsylvania, Ohio, and Illinois. The season seems to be one of very
severe aphid injury, many species having been reported.
A new species of aphid on birch is occurring in such numbers in the cities
of southern Connecticut as to be a nuisance.
Codling moth injury is reported as generally normal over the Eastern States,
somewhat above normal in the East-Central States, and decidedly below normal in the
Pacific Northwest.
The apple tent caterpillar has been unusually numerous in eastern Massachu-
setts, and moderately abundant in New York State, southern Pennsylvania, Delaware,
Wisconsin, and Minnesota, especially where orchards have not been well cared for,
and the forest tent caterpillar is reported as more numerous than usual in eastern
Massachusetts, Connecticut, New York, and New Jersey. In Oregon the pest occurred
in such numbers near Corvallis as to occasion newspaper write-ups of trains being
delayed by hordes of these insects on the tracks.
The cankerworms attacking both orchards and forest trees are reported as
abnormally abundant in New York, New Jersey, Wisconsin, Minnesota, and Iowa.
The imbricated snout-beetles are reported as defoliating apple trees in
Illinois and Nebraska, and the oriental fruit-moth threatens considerable damage
to late peaches in Virginia.
The rose chafer is occurring in very unusual numbers throughout the New
England and Middle Atlantic States as far south as North Carolina and Tennessee,
and west to Indiana.
The grape leaf hoppers are appearing in alarming numbers in the grape-growing
sections of New York, Pennsylvania, and Ohio.
Last year we reported the occurrence of an Anomala as very destructive to
sugar cane in Hawaii. This is occurring in a nursery in Connecticut. What is
supposed to be the larva of this species is reported from the same vicinity, where
it is infesting lawns.
Brood XIV of the periodical cicada is reported as appearing in large numbers
in eastern Massachusetts; central Long Island; Adams County, Pa.; Clarmont County,
Ohio; and Tennessee, and scatteringly in Maryland, Virginia, and Indiana. Erood
XXII of this insect appeared in large numbers in the six counties where it W:as
reported in past years in Mississippi, and also in three additional counties in
that State. In Louisiana it appeared in Livingston, East Baton Rouge, Ascension,
East Feliciana, and West Feliciana Parishes.
OUTSTAHIBISG- ENTOMOLOGICAL FEATURES FOR CANADA FOR JUNE, 1923.
A heavy set of fruit, with the possible exception of plums in certain
sections, is reported from the orchard sections of Canada. Cereal crop prospects
in the Prairies are excellent. The early part of June was cool and rather wet in
■IDc
western Caada and warm and dry in the east. In northwestern Quebec plant and
insect activities centering about the time of the opening of the balsam buds were
relatively several days earlier than the past two years despite the cold spring.
A heavy smoKy atmosphere resulting from forest fires apparently raised the night
temperatures and possibly accounts for the early conditions.
The strawberry weevil is the cause of many inquiries from Ontario and the
Maritime Provinces, particular injuries being caused in strawberry plantations
in southern Ontario and in the vicinity of Cumberland County, Nova Scotia.
The San Jose scale has been found on orchard trees at Spence's Bridge, B„ C.
This insect was believed to have been eradicated. The importance of this item lies
in the fact that this is the only point in British Columbia where this insect is
known to occur.
Owing to the great prevalence of th« fungous disease, Entomonhthora
sphaerosperma. of the apple sucker, Psvllia roali. this insect is not nearly so
abundant in Nova Scotia this season, although its distribution has been somewhat
enlarged .
The spring cankerworm is occurring in outbreak form on apple and elm trees
in many sections of southern Ontario.
Regionally throughout western Ontario the flight of June beetles has thus
far been light.
In summarizing the late autumn and winter mortality of the European corn
borer at various points throughout the entire infested area in Ontario, but 6.4
per cent of the larvae were found to have died. The reduction of the larvae in
the field by birds this past winter in ordinary crop refuse was of no practical
importance in control. This indicates clearly that these natural control factors
can not be depended upon to assist materially in the control of the pest. The
excellent results following early fall and careful spring plowing in reducing the
number of larvae have been strikingly illustrated this spring.
Hessian fly injury is generally light throughout western Ontario.
Grasshoppers are reported in severe outbreak form in southern Saskatchewan.
Wirdworms are occurring in local outbreaks in Saskatchewan and Manitoba and
much damage to wheat and corn has been caused.
The lesser clover-leaf weevil appears to be more abundant than the clover-
leaf weevil this year in southern Ontario and is decidedly more injurious.
The elm bark -louse has again made its appearance in considerable numbers
in the vicinity of Ottawa. This insect is one of the worst enesmiaiof the elm
in Canada.
CEREAL AND FORAGE- CROP INSECTS
1 ^SMSML PEEPERS
CUTWORMS (Noctuidae)
Massachusetts A* I. Bourne (June 23): Cutworms are still doing some damage
on the Cape, there they are mich more destructive on truck
crops than usual this season.
Michigan
Wisconsin
South Dakota
Nebraska
Idaho
R.H.Pettit (May 28): I received today some specimens of cutworms
from Benzie County, in the northwestern part of the Lower
Peninsula, with statement that fifty-two were taken from around
one sweet-clover root which was plowed up in making ready
for a cornfield. Last year the same kind of cutworm seemed to
he attacking the roots of sweet clover.
S.B.Fracker (June 15): Moderate damage reported to corn,
tomatoes, ana other crops in Rock, Dane, Grant, Vernon, Pepin,
Monroe, Wood, Portage, and Lincoln Counties. Reported ahsent
in Burnett County up to May 15 at least.
A.L. Ford and H.C.Severin (June 8): Cutworms are seriously
damaging young corn in many places in the southeastern part
of the State. Many farmers have been forced to replant. In
no case has there been injury to corn on fall-plowed land,
M.H.Swenk (May' 15- June 15): Cutworms , despite the cool, wet
spring over most of the State, have not been normally abundant
or destructive. During the third week in May, however, heavy
flights of the moths of the western army cutworm (Euxoa
auxilj.arisN, . resulting from an abundance of its cutworms the
preceding month, was taking place in Arthur County.
Don B. Whelan (May 2k) : Cut-."orms ate all green growth on 5
acres of alfalfa at Blackfoot. Control was obtained by the
use of poisoned-bran mash.
W IRE^ORMS ( Elat er idae )
Ohio F» W. Poos (June 7): ^e have noticed Limonius sp. occasionally
on our experimental plot at Sandusky this year, but to date no
damage to the corn is apparent.
Indiana J. J. Davis (June 19): Report of injury to corn at Reynolds on
June 15, also report on June l6 at Columbus.
Illinois W. P. Flint (June 19): Unknown species of wireworms have beai
abundant and destructive. Several counties in the central part

of the State report 5 "to 10 per cent of the cornfields damaged.
Individual fields where actual counts were taken show 5 to 50
per cent of the corn killed.
Stewart Lockwood (June 1): A farmer at Roberts sent in some
larvae he found destroying his field of wheat. He said that
a large part of the field was destroyed,
Claude Wlkeland (May 26): Adults are numerous at this time in
the southwestern part of the State and females are ovipositing
freely. This pest is becoming increasingly abundant from year
to year and gradually spreading to irrigated land that has
remained more or less free for years. It is impossible to raise
corn or potatoes in certain restricted localities. Wireworras
are a pest of major importance to growers of potatoes, lettuce,
and corn,
M. C. Lane (June U) : Under separate cover I am sending by this
mail a package containing five larvae of the genus Pheletes
collected by me at Toppenish, Wash., June 1. These larvae are from
the same nursery as those reported by Mr» Newcomer about May 17
and are without doubt the wireworm that is doing the damage.
My own observations and collections lead me to believe that this
is the wireworm that is doing all the damage to crops under
irrigation in the Yakima Valley and several other irrigated sections
in the State besides. The damage in the nursery was mostly
in blocks of seedlings on land that had been in potatoes for
several years previous. I will also include a mounted specimen
sent me by Mrt Newcomer (Pheletes occidentalis Cand. ) which he
states was picked up dead in the nursery where the larvae were
found. It may or may not be the adult responsible, but I wish
to have this adult determined and returned to me for future
comparison. In outdoor cages here I have several larvae of the
same lot as those being sent, and hope to procure adults before the
summer is over. If I succeed I will send the adults in for
determination also.
GRASSHOPPERS (Acridiidffi et al.)
iy
S, B« Fracker (June 15) : Grasshoppers, most/Melanoplus atlanis
are slightly worse than last year at this date in Oneida, Florence,
aand Forest Counties. Not as bad in Price County. In pastures
only so far. Reported present in Vernon County by County Agent,
R, L. Webster (June 12): Some rye fields in McHenry and Bsttineau
Counties are reported as having been plowed under because of damage
by young hoppers. They .are increasing in numbers.
A. L, Kord and H. C. Severin (June 8): According to the numbers of
eggs hatching during the last of May, trouble from Melanoplus
bivittatus Say, is expected in the alfalfa seed-growing.isection,
Fall River, Custer, Pennington, Meade, Butte, and possibly some in
- Ill -
Lawrence C012nti.es. To fate the only known pending outbreak
of Melanonlus differential is is in Bon Homme County at the
month of Dry Schoteau Creek. In this locality the eggs are
numerous.
Nebraska M.H.Swenk (May 15-June 15) : Grasshoppers, chiefly Melanoolus
Myittatus.were found to "be hatching out abundantly in the
irrigated district of the North Platte Valley during the first
week in June, promising continued injuries in some localities.
About half of them had emerged from the eggs by June 8.
Kansas J. I, Mc Col loch (June 21): Grasshoppers are appearing in large
numbers in all fields in Ellis County.
Texas R. R. Reppert (June k): From Fort Worth to San Antonio, north
and west,, the country is suffering the most serious outbreak
of grasshoppers since 1901 and great difficulty is experienced
in obtaining poison. Species differ entialis predominate? •
M. C Tanquary (June S) : Very serious grasshopper outbreaks
are occurring in about a dozen western and mid-western Texas
points, (June 15): Numerous reports from about a dozen counties
in central and western Texas indicate more serious grasshopper
outbreaks than hsrve occurred in this State for several years.
Poisoned-bran mash is being used with success.
Wyoming Syewart Lockwood (June l): Melanoplug bivxttatus are now about
two-thirds hatched and are juzt starting to work on the edges
of crops in Park County. The infestation promises to be very
heavy in corn and alfalfa.
Utah H.J.Pack (May 26): The black cricket, Anabrus ,simpl.exJ threatens
much greater damage this year than was done last year- These
crickets occur in menacing numbers in the southern part of the
State, where they are already in fields of grain and alfalfa.
There are a few in Cache County and considerable numbers are
reported in Uinta County.
Idaho Don B. Whelan (May 2k) : Grasshoppers are more abundant in
Bingham County than last year or during preceding years. A very
extensive and severe outbreak in 1922 required a well -organized
and long-conducted poisoning campaign. About 10: per cent of
tthe eggs are now hatched. Blister-beetle larvae, Epicaiat-a,
maculata , are numerous. (May 25): Anabrus simplex damaged
one end of a wheat field at Fairfield and then moved on to a
pasture. They are much more abundant than last year.
Oregon C* M. Packard (June 9): In Klamath County hoppers are still
small, but very abundant in practically all cultivated valleys.
Systematic poisoning is being carried on under direction of the
- 112 -
County Agent, with excellent results in most localities. If the
outbreak had not been vigorously fought extensive and serious
damage would have taken place.
California C» M. Packard (June 7): At the Klamath Irrigation Project hoppers
are still small and in isolated bands, but fehey are spreading*
Several species are present but not determiaaMfiein the young
stages now present. Extensive poisoning is now in progress with
varying success from excellent to poor, on the whole good. An
area of 50,000 acres is covered by a spotted infestation.
California Weekly News Letter, Vol. 5, No. 12 (June l6): Adviees
received by the California Department of Agriculture from Horticultun'lJ
Commissioner for Modoc County indicate heavy infestations of grass-
hoppers both in Modoc and Siskiyou.
In the Tule Lake section of Modoc and Siskiyou grasshoppers are
menaching twenty thousand acres of grain. Several thousand acres
of "reseeded land" in this section are literally covered with small
hoppers. The U. S. Reclamation Service has given $5,000 to combat
the grasshoppers and every cropper is devoting practically all time
to scattering poison.
During favorable weather for poisoning as much as 10,000 pounds
of poison bran mash is scattered daily. The Horticultural Commissioner
for Modoc County is putting on crews to assist the croppers.
Ingredients for mixing the poison are being bought inrjcarload lots
and everything possible is being done to relieve the situation.
APHIDS (Aphid idae)
Illinois W» P. Flint (June 19): The English grain aphidr Macro siohutn .pranarUBm.
is generally abundant in wheat throughout the State but, not in
numbers sufficient to cause injury to the grain,
Indiana J. J. Davis (June l£}: The grain aphid, Macro siphum granarium .
has been abundant the past two weeks, apparently with no appreciable
injury, however.
Texas 0. G. Babcock (May 9): For the first time in three years the weather
has been very favorable for the development of aphids in general in
West Texas within a 100-mile radius of Sonora. The spring was late
and cool, with an abundance of moisture. Weeds and shrubs of all
kinds have made wonderful growths, exceeding normal growth by 100
per cent in many cases. Aphids upon a rare but wild 0-ilia, on
petftateacap .domestic flowers, plum trees, and roses and other plants
are or were conmon. No predacious nor parasitic enemies to mention
have been present until. mow, when hot and dry weather is setting
in. The aphid enemies are now becoming very numerous. Grain aphids
are also present upon volunteer barley.
WHITE GRUBS (Phyllophaga spp.)
New York L. J. W. Jones (June 15): May beetle, larvae about 1/k inch long,
-113-
2 to 5 per square foot, where observed. Observation was not
general, and these might have hatched from an egg cluster.
Believed to be increasing ( 20 per cent more than last month)
at Bainbridge, in Chenango County.
Soy Latham (June 20): Swarms of June beetles have been the
heaviest ever observed at Orient, in Suffolk County.
Wisconsin S. B. Fracker (June 15): Adults are riddling oak and poplar leaves
from Madison to Piatt eville, in the southwestern part of the
State. In Vilas County both larvae and adults are present,
Illinois C. C. Compton (April 30) : Adults of Phyllophaga fusca Froe. are
beginning to appear at Aurora in moderate numbers.
W. P. Flint (June IS) : There was a heavy flight of June beetle
adults during the latter part of May and the first of June. Many
oaks in scattered stands of trees were nearly defoliated.
South
Dakota
Idaho
A. L, Ford and H. C. Severin (June 8): Adults are more numerous
in the southeastern part of the State than for year^ .according,
to observations and reports. This indicates that this section
will suffer during the growing seasn of 1^2h.
Don B. Whelan (May 2U) : Adults are reported numerous but no
injury is reported.
WHEAT
CHINCH BUG (Bliss-us leucopterus Say)
Ohio Herbert Osborn (June 2): Occasional bugs have been taken in
sweeping in meadow land at Columbus. No serious infestations
have been observed so far.
Indiana J. J. Davis (June 15) : On June lU the first report of bugs
migrating from grain to corn was received from Jasonville, in
Greene County. Bugs are abundant in small grain fields. Severe
outbreak is anticipated.
Illinois W.P. Flint (June 19) : Hatching of the chinch bug eggs was greatly
delayed by the cool wet weather. The first young were found in the
field June J. Rains have had some effect in lessening the number
of eggs laid, but have not made any material decrease in the
chinch bug numbers. There will apparently be a very heavy
infestation covering more than three-fourths of the State. The
degree of infestation varies locally, being most severe throughout
central and south-central sections.
Iowa Fred D. Butcher (June k) ; On May 30 adults were present in wheat
fields in Lee County, 1 to 12 per stool, and mating. No
were found.
-11-
South A* L. Ford and H. C. Severin (June 8): Charles Mix, Bon Homme,
Dakota Douglas, and Hutchinson Counties wintered many "bugs successfully.
Chances are good for trouble in these counties. Recent beany rains
in this section undoubtedly have relieved the situation to some
extent.
Nebraska l.1c Ho Swenk (June 15): The chinch bug began appearing about May
20 in aba:-) dance '".in the wheat fields of southern Pawnee, Gage, and
Jefferson Counties and in unimportant numbers in the wheat fields
north of these counties to the Platte River. During the week
from May 17 to May 24 there were sufficiently heavy rains in this
region to give something of a setback to the bugs, but they are
still very abundant in some fields. Even heavier rains occurred
in the region farther west that was found to be more or less
infested last fall, from Jefferson to Furnas Counties, and no
reports of great abundance of chinch bugs in that area have been
received this spring,
Kansas J, W. McColloch (June lG): Owing to backward weather conditions,
hatching has just begun in the northern half of the State. Chinch
bugs are more abundant than in an average year and less abundant
than last month, because of abnormal climatic conditions. Fungus,
egg parasites, and ladybeetles are present. As many as 15 or 20
diseased bugs to the square foot occur in small grain, and from
10 to 15 per cent of the eggs are parasitized.
Texas M. C. Tanquary (June 15): Chinch bugs have been reported as
occurring in destructive numbers in Denton and Houston Counties.
They have been noted as baapgpresent in small patched of sweet
corn in Brazos County.
HESSIAN FLY (Phytoohaga destructor Say)
Iowa Fred D* Butcher (May 28): September 20 seeding is heatfily
infested, from 80 £0 90 per cent, late seeding, after October
5, from 30 to 50 per cent, from spring flight within a radius of
1 to 2 miles in Mills County. (3!une $) : This pest is well
distributed over Monroe County, and the spring injury will no
doubt be severe. Straps are falling badly now.
Nebraska M. H. Swenk £May 15- June 15) : In spite of the dry summer and
fall of 1922, the fall brood appeared in strength in the early-
seeded winter wheat in some parts of eastern Nebraska, and this
strength was greatly augmented by the heavy spring brood of 1§23,
so that the pest is now so abundant as to cause some serious losses
in the present crop, and form a menace for the new crop to be
seeded this fall. Weather conditions this spring have been
unusually favorable for the Hessian fly. The insect is well
distributed over much of southeastern Nebraska, being locally
-115-
injurious here and there as far west as Furnas County, "but the most
serious injury is practically confined to the block of four counties
"bordering the Missouri and south of the Platte, Cass, Otoe, Nemaha,
and Richardson, with the adjacent counties of Johnson and Pawnee.
In Cass County the infested fields are mostly the early-seeded ones,
and those show frequently from ,75 per cent to practically 100 per
cent of the stems affected, causing an estimated average local
damage to the crop of from 5 T^r cent to as high as 20 per cent in the
more eastern townships. Otoe Ccunty is also seriously infested,
especially the eastern portion, only slightly less so than Cass
County, and the s; ilso "be said of Nemalia County. In Richardson,
Pawnee, and Johnson Counties the injury is less intense, being the
worst inr£j.chiiidaon County. Northern Bufcler County has considerable
infestation also. The fly larvae were beginning to change into
"flaxseeds'1 on Hay 21, which marked the beginning of the end of active
injury. A considerable number of the very badly injured fields
WfeEJS? plowed up and planted to corn during the last week in May and
the first week in June.
7HEAT J0INT70RM (I so soma tritici Fitch)
W. P. Flint (June 19): This worm is present in nearly all fields,
and in many fields where examinations have been made more than 25
per cent of the straws are infested.
0. C. McBride (June 22): In Greene County 12| per cent of the wheat
in several fields is injured with heads blasted and straw lodging.
Grubs are nearly full-grown. In Mississippi County there isc^ about
2 per cent injury and 5 per cent in Phelps in many fields.
A SaYJFLY (Dolerus sp. )
ff« A. Ostrander (June Ik): Sawfly larvae are damaging wheat in the
northern half of Elkhart County, near the Michigan State line. Larvae
are eating foliage and green wheat heads, doing considerable damage.
FALSE WIREUCRMS (Eleodes hisnilabsis. E. 1 etcher i
and E. car c una r ia'j
Claude TJakeland (May 20): These are pests of major importance to
the wheat raisers on the dry-land farms of eastern Idaho. Usual
general injury caused in many fields with an occasional field that
is severely injured and almost entirely or completely killed out.
SUGAR-CANE BORER (Diatraea saccharalis Fab „ )
T. H. Jones ^ Complaints of injury by larvae of the first generation
have been received from 'west Feliciana, Avoyelles, St. Helena, East
Baton Rouge, and East Feliciana Parishes-, larvae, pupae, and adult
from St. Helena Parish. It is interesting to note that the complaint;
of injury come from a section of the State where the -sugar-cane moth
stalk-borer has caused severe injury to corn during the past few
years. Moths from material sent in began issuing in our insectary
on June U.
fcJLXb*
Ariaona V, L. Wildermuth (June 6): Report of Diatraea, probably D.
lineolata (although it may be zeacolella) . received from TuciStini,
damaging corn 33-1/3 Per cent.
STALK BORER (Papaipema nitela Guen. )
Connecticut M. F. Zappe (June 21): Very young corn, less than 3 inches
high, is badly infested at Hamden. This borer seems ibo be more
abundant than in an average year.
B ILLBUGS (S-phr.no -chorus sop . )
J. J. Davis (June 15): Cn Juno 7 Spbenouhorus parvulus was
reported damaging corn in low spots of field 5 miles northeast of
Mulberry. This field was in timothy last year, (June l6): A

beetle, probably 3pI'^encpJuxrus c-er
irr about 1/2 inch long
and of a grayish color with a faint stripe. It has a bill about
1/4 inch long with which it punctures the young plant. It has
destroyed about 500 acres of corn at DeMotte in the Kanbaba
marsh land, and the proppects are that it will get that much more,
SEED-CORN MAGGOT (Hrlemyia cilicrura Rond. )
C R. Crosby (June 8): Corn infested with Phprbia fusiceps
was received from Cayuga County. In many cases the farmers have
had to replant the field.
Chas, C. Compton (May 26): The seed-corn maggot has been more
troublesome this spring than usual in the northern part of the
State, necessitating replanting in several cases.
PALE-STRIPED PLEA-BEETLE (Systena taeniata Melsh.)
Indiana J. J. Davis (June 15): On June lk the pale-striped flea-beetle
was reported as practically destroying 20 acres of corn and
moving at the present time to an adjoining field near West Point,
10 miles southwest of LaEayette. On June 15 the same species
was destroying 10 acres of corn at Goodland.
Illinois W. P. Elint (June 19): Pale-striped flea -beetle larvae, var«~
blanda. have been very abundant throughout central and northern
Illinois and have caused considerable damage to corn during the
first two weeks after planting. A number of cases have bEen
reported where the adults were all of this species.
ALFALFA AM) CLOVER
ALFALFA WEEVIL (Fhvtonomus posticus Syll . )
Idaho Don 3. Whelan (May 2h): Larvae are quite noticeably present in
terminal buds of alfalfa at Blackfoot and Aberdeen. Abundance is
greater than in 1322.
-117-
Claude Wakeland (May 25): Activity of adults is extending over a
long period of time- The first larvae were observed in the field
in southwestern Idaho May 2, the first pupae May 22. Larvae are
abundant in fields, also eggs, and females yet contain large number e
of eggs to be deposited. Communities severely affected in 1922
are in general less infested, but severe injury is occurring or
will occur in communities where not noticed last year. Bathyplectes
curculionis occurs generally but in small numbers around Caldwell
and Parma.
ALFALFA CATERPILLAR (Eurymus eurytheme Boisd. )
Idaho Don B. Whelan (June 8): Damage at Wendall is slight, about 1 per
cent. Quite a percentage of terminal leaves are eaten. Injury
resembles that of alfalfa weevil when not abundant.
FALSE CHINCH BUG (Nysius ericae-j. Schill.)
Minnesota A. G. Ruggles (June 7): The false chinch bug was discovered
doing considerable damage in alfalfa fields at Milaca.
CLOVER -LEAF WEEVIL (Hypera -punctata Fab. )
Idaho Don B. Whelan and Claude Wakeland (May 20): The steady and
consistent increase of this insect while slow would suggest that
it may become a pest of major importance at some future flirae. It
has become more abundant each year during the last three years.
Several reports of injury to alfalfa and clover have been received
this season. Attention is called to it mostly by farmers taking
injury of it to be due to the alfalfa weevil. Locality, in Boise-
Payette Valley.
LESSER CLOVER-LEAF WEEVIL (Phytonoimis nigrirostris Fab. )
Ohio T. H. Parks (May J,l): These larvae are now common in the embryo
heads and buds of red clover at Columbus, also beneath the leaf
stipules. Some are already nearly full-grown. Prospects are good
for interference of normal blossoming due to the presence of the
larvae. This has been the worst insect pest of red clover for
several years in western and central counties. (June 23): The
pest is present at Columbus in the usual numbers, but good growing
weather enabled the clover to outgrow its damage. After watching
this pest for four years, we notice parasitism increasing and
beginning to have its effect upon the host.
RYE
SORGHUM WEBWQRM (Celama sorghiella Riley)
Indiana J. J, Davis (June l6): We have received specimens of what /certainly
must be Celama sorghiella. attacking the developing grains in the
heads of Rosen rye at Newport. This is the first record we have
-IIS-
ever obtained on this insect attacking rye; in fact I do not
recall its ever having "been found injuring this crop "before.
Our correspondent ha^s advised us that it attacks nothing
except Rosen rye, which is a ne" variety for that section.

Massachusetts A. I. Bourne (June 23): Aphids were about normally abundant
^the last of May and the first of June in unsprayed orchards,
but were held in absolute control in the blocks where careful
spraying was done. Reports indicate that aphid: occurrence
is much less than is normally the case and they are being
taken care of very well by the Goccinellids.
Connecticut W. H. Darrow (June): Lldylbug larvae and another small downy
covered worm are apparently exterminating the aphids in certain
orchards.
C. D, Clark (June 15): This insect is reported from Wilton
and Greenwich, abundance as compared with an average year
being less. In Wilton, larvae of ladybeetles are abundant.
New York C. R. Crosby and assistants: Infestation was rather severe
early in the month, but heavy rains have reduced the outbreak
to a negligible factor for this season.
Pennsylvania
Ohio
S. W. Frost (June 8): The green apple aphid has not been
found serious in Adams County this season. It has become
more numerous during the past few weeks, however.
E. W. Mendenhall (June 12): Abundance of green leaf aphids
or plant -lice is far greater than last year on apple trees
in this section and they seem to be hard to control. There
are a number of commercial apple: .orchards in this locality.
Connecticut
New York
ROSY APPLE APHID (Anuraphis roseutr Baker )
W. E. Britton and Philip Garman (June 12): This insect is not
numerous enough to be serious. I believe it is generally
much less abundant in this State than last year. It has been
reported from Greenwich, Deep River, and Haddam and is more
abundant than in an average year in this locality.
C. R. Crosby and assistants: The rosy apple aphid is over the
appl e -growing section, doing serious damage in Oswego and
parts of Orleans Counties.
-US-
Pennsylvania S. W„ Frost (June 8): The rosy apple aphids ^ere very abundant
in Adams and Franklin Co-unties this summer. The winged forms
are appeal ing in largo numbers and the aphids are migrating,
Ohio E. 17. Mendenhall (June l6) : Rosy apple aphids are very had
in the commercial and farm orchards in Delaware County.11 Black -
leaf ;U0" 13 being used, but they seem hard to control. The
infestation seems worse than usual this year.
Indiana H. F. Dietz (June 22): Unusually abundant this year.
Illinois VT. P. Flint (June 19): The rosy apple aphid is very abundant
througho-at the central and southern part of Illinois. Infestation
is decreasing at the present time owing to attack of syrphus
flies, la&ybugs. and other insect enemies.
CODLING MOTH (Carpocansa nomonella L. )
New York C. R» Crosby and assistants: The first eggs of the codling
moth began to appear in orchards on June 3, and 6, in Orleans
County. The weather has not been favorable for codling moth
development. Very few moths have emerged to date. Observations
at Sod-us, Wayne County, indicate that codling moths are all
in the larva stage. In the southern part of the county pupae
and adults were found in abundance. The adults were just
emerging from the pupa cases. No eggs were found.
Virginia L. A. Stearns (June 21): The first cocooning of first-brood
larvae occurred June 8, and the first pupation, June 11. Full-
grown worms have since been found leaving the fruit in rapidly
increasing numbers.
Illinois '7. P. Flint (May 18): The first adults of the codling moth
emerged at Carhondale on May 7- Judging from the pupation
records at other points in the Stale, eggs of the first brood
will be hatching from May 20 in southern Illinois to about
June 10, in the northern part of the State. (June 19) : This
moth is present in more than average numbers. Adults are
still continuing to emerge from overwintering larvae.
Idaho Claude V/akeland (May 28) : First emergence was observed at
Parma May 18, the first eggs in the laboratory May 26.
Washington E. J. Newcomer (June 18): Owing to the cool rainy weather the
codling moth is not nearly as numerous as last reason. This,
together with the unusual efforts being made by the growers
to gight it, should result in a very clean crop of fruit.
-ISO-
FRUIT-TREE LEAF-ROLLER (Cacoecia argyrospila Walker)
New York C. R. Crosby and assistants: In Orleans County, leaf -rollers
have "begun to.jpu.pate. They are very plentiful throughout
the county, and are doing considerable damage in some orchards,
Sa Monroe County this insect is common and is doing considerable
injury. Leaf -rollers are about all hatched, and are rather
abundant throughout the entire county. They "are abundant on
apples in many orchards. Well-sprayed orchards do not have
as many as those not so well taken care of. It begins to appear
that more aggressive measures may be necessary next year.
This insect is commonly found in Wyoming County in neglected
and unsprayed orchards. In Wayne County it is prevalent over
the whole county, and abundant where no pre-blossom spray'^was
applied. In most orchards in Ontario County this insect
can be found, but it is not bad where the spraying has been
good. In Chautauqua County, it is frequently found but is not
abundant enough to be destructive. It is very general in
distribution and causing considerable damage in Oswego County.
It is found generally in G-enesee County, damage being from 1 to
10 per cent. In Dutchess County, it is rather prevalent,
especially in the orchards which received no pre-blossom spray;
2 per cent injury, generally distributed.
Missouri L, Haseman (June 5): This insect is not abundant in any one
section, though it is scattered over the State and more or
less serious where found.
APPLE AM) THORN SKELETONIZER (Hemerophila par iana Clerck)
Massachusetts A. I. Bourne (June 23): A few specimens of this pest were
sent in on June 1^, from the town of Sheffield. At the time
of arrival one of the specimens had pupated.
Connecticut J. A. fetfcer (June 22): The first brood has matured in Mansfield^
and is more abundant than in an average year.
F. A. Bartlett (June 23): Reported from Fairfield, Abundance
apparently more than a year ago, and less than in 1922.
New York C. R. Crosby and assistants: Larvae are now working in small
numbers on some of the trees. It is expected that the calyx
application will clean up this pest in Dutchess County. In
several parts of Rockland County this pest was observed in
small numbers the past week.
M. D, Leonard (JLpril 15) : Roy Latham reports that moths
were out in large numbers on this date. A few were seen the
last few days of March at Orient, Suffolk County. They were
found to winter over in buildings and under loose bark. (June 22)
The Albany County agent, reports considerable skeletonizing
at present at Ravena.
- 121 -
E. P. Felt (June 22) : There is severe skeletonizing of leaves
at present in iseveral orchards.
BUD' TSOTH (Tmetocera, oceftlana Schif . )
New York C. R. Crosby and assistants: Fairly abundant and serious
throughout the apple growing sections especially on young and
poorly cased for orchards.
Minnesota A. G. Ruggles (June 7): The hud iworm was found doing considerable
damage at Orchard hardens. This is the first time this insect
has been discovered in numbers in the State. A closely related
form of Stenoma algidella was also found alogg with this species.
.GREEN FRUITWORM (Xvl ina antennata Walker)
New York C- R. Crosby and assistants: In Oswego County this insect is
reported as doing considerable damage in two orchards with 2
per cent injury. In Dutchess County it is generally distributed.
It is fairly serious in some neglected orchards in Genesee County,
Wlt&.l to 5 per cent injury. Two or three serious infestations
of the green fruit worm occurred in Columbia County, one of
these being in fact the worst infestation ever seen. The insect
is doing an unusual amount of damage here this year in general.
Ifr Ofitar io County it is rather numerous, especially in orchards
not well sprayed. Not plentiful in Orleans County, but a few
are to be found in some orchards, In Ulster County this insect
is general but not common or serious. In Monroe County it is
present but not abundant, and in Chautauqua County it is found
only occasionally in various parts of the county.
TENT CATERPILLAR (Malacosoma americana Fab.)
Massachusetts A.I.Bourne (June 23): As predicted earlier in the season,
reports indicate that tent caterpillars were abnormally abundant
and when neglected did considerable damage in Franklin, Worcester,
and Barnstable Counties, and in fact throughout the State. In
many places it is recorded as the only apple pest of importance
this season.
Connecticut F. A. Bartiett (June 23): This insect is reported from Fairfield,
as being more abundant than last year.
I. f7. Davis : This pest is reported from Windham County,
increased in abundance as compared with average year.
W. E. Britton (June 23): The tent caterpillar is particularly
abundant in Litchfield County, but abundant all over the State.
- 122 -
Hew York C. R, Crosby and assistants: Tent caterpillars are quite
numerous in all parts of Oswego County. They are found in
Ontario County in most orchards that have not teen sprayed,
not serious in Orleans County; also observed on roadside trees,
in Genesee County.
J. T. M. Forbes (June 2): Tent caterpillars are coming into
the last stage* This is to be expected early in June, but is in
direct contrast with the belated development of most other
insects this season,
Leland J. TE. Jones (June 10): Owing to unfavorable and cold
weather last month, the report was not exact; this pest is
increasing over former years at Bainbridge. Little is to be
done to control it.
Pennsylvania S. W. Frost (June 8): The apple tent caterpillar is abundant
on. neglected apple, plum, and cherry trees in Adams County.
Delaware C« 0. Houghton (May 17): Caterpillars are now migrating to
find suitable places for spinning up. Serious injury has been
done in many cases, tnees being wholly defoliated.
Wisconsin S, B. Fracker (June 15): This insect is reported in Columbia,
Grant, and Marathon Counties; and has been pfensonally observed
in Dane, Rock, and Walworth Counties.
Minnesota A. G. Ruggles (June 7): The tent caterpillar was very abundant
in Orchard Gardens. Ordinarily we see very little of this
insect in Minnesota. In this part of the State the orchards
have not been well taken care of and the insect seems to be
on the increase.
SPRING CANKFRWORM (Paleacrita vernata Peck)
New York C. R. Crosby and assistants: This insect is quite generally
prevalent over the western New York apple growing section. It
was so serious this year in Genesee County that a spray ring
has been formed to fight this pest. It is estimated that the
trees in the infested area are 75 per cent defoliated.
Wisconsin S, B. Fracker (June 15): The spring cankerworm is less
injurious than in 1921 and 1922 in southeastern counties, but
worse from Madison to Spring Green.
C» L. Fluke (June 22) : The spring cankerworms have appeared
in the southern part of Wisconsin in great numbers. At this
date the damage is nearly over.
Minnesota A. G. Ruggles (June 7): The spring cankerworms seem to be
as bad this year as ever in many sections of the State,
123
Iowa Fred D. Butcher (June 1): Cankerworms are stripping elms
and unsprayed apple orchards in different parts of the county.
PALL C ANKERS ORM (AlsoDhila -pometaria Harris)
New York C* R. Crosby and assistants: In Orleans County, the fall
cankerworms are working in orchards in the southern part of
the county, while in Wayne County, they are unusually abundant
in three neglected orchards.
Wisconsin C. L. Fluke (June 22) : The fall cankerworms have appeared in
the southern part of Wisconsin in great numbers. At this date
the damage is nearly over.
Minnesota A% G. Ruggles (June 7): The fall cankerworms seem to be as
bad this year as ever in many bsect ions of the State.
APPLMED-BUG (Heterocordylus malinus Reut . )
Massachusetts A, I. Bourne (June 23): The apple red-bug is reported as being
(fiairly abundant in Pittsfield, in Berkshire County, in spite of
rather careful spraying. In the Ccllsgp orchard the red-bug
is found to be very generally distributed a:id troublesome. It
should be nearly through its work' at this time, however, for
the season.
Connecticut W. H. Darrow (June): This insect is reported as attacking the
apple throughout the entire State of Connecticut.
New York C. R. Crosby and assistants: The apple red-bug has been
observed in moderate numbers in numerous orchards in Dutchess
County, but only avfew have been found in Ontario County, and
it is very scarce in Ulster bounty.
FALSE APPLE RED-BUG- (Lygidea mendax Reut.)
Connect icut
New York
J. A. Manter (June 22): This insect is reported as attacking
the apple in Mansfield. It is less abundant than in an average
year for the last few years.
C* R. Crosby and assistants: In Ontario County the false
apple red-bug has been seen in nearly every section. Although
>a few orchards have been found where they were plentiful, they
have been hatching rapidly during the past week. In Wyoming
County they .were first found on May 31, one orchard being
seriously. infested. In Monroe County they were not abundant
but were present. (In Orleans County, nymphs have reached the
third and fourth instars, and are abundant in a few orchards,
while in Ulster County, the red-bugs are in the third stage, and
- 124 -
abundant in "but three locations, none having been seen iSow for
2 weeks. In Genesee County to the present time, these insects
have been found in the third instar, and several orchards
required control measures. In Nassau County they were found
in one orchard this past week, while in Onondaga County they
began hatching in hut one orchard where they are very numerous.
In Wayne County, the nymphs are now in the fourth stage, while
at i : Dutchess County they were observed in moderate numbers
in numerous orchards.
APPLE LEAFHOPPER (Empoasca mali LeB. et al.)
Massachusetts A. I. Bourne (June 23): The early hoppers of the apple were
very bad indeed in many orchards but were readily handled by
the spraying and dusting campaigns.
New York C. R. Crosby and assistants: In Ontario County, apple leaf-
hoppers are abundant all over, while in Orleans County, they'ari
abundant throughout the county and are now changing to adults.
In Ulster County they were found in but 2 orchards in plentiful
numbers. They are abundant in Monroe County, but not yet
severe. The majority of these insects have reached the adult
stage in Cenesee County, and are found generally in younger
orchards. In Wyoming County they are present particularly
in the yourgsDr orchards but not serious, causing some injury
in a few young plantings. In Wayne County they are very
abundant over the county, especially in the northern half, and
have become quite serious in some orchards. Most damage has
been done on younger trees. In a few individual cases a
special spray was recommended* They' jar e hatching in large
numbers.
Wisconsin
Van W, Cass (June 10)
Madison,
This insect is reported as "bad" in
Connecticut Philip Garman (June 21): The rose leafhopper has been reported
as attacking the apple at Hamden, and more abundant than in an
average year.
Pennsylvania S. W, Frost (SCune S): The rose leafhopper is exceedingly
abundant on apple in some orchards in Adams County, The
characteristic white stippling on the leavES is already very
pronounced. A small percentage have transformed, but the
greater proportion are still nymphs.
SAN 50SE SCALE (Aspidiotus perniciosus Corns t.)
Massachusetts A. I. Bourne (June 23): The San Jose scale seems to be
increasing in abundance*
New York C. R. Crosby and assistants: The young of the San Jose scale
appeared on June 11, and were found in plentiful numbers in but
- 125 -
a few orchards in Orleans County, while in Genesee County they
were found generally serious in Bergen. They are slightly
more common than last year in Monroe County.
R. W. Leiby: This insect has beai increasingly injurious in the
commercial sandhill section on peach trees during the past
two years. Trees that received two applications of lime-
sulphur at standard strength during the same winter continue to
show heavy infestation. An unusual number of parasitic emergence
holes are now prevalent.
Oliver I. Snapp (June 20): The general scale infestation in the
Georgia Peach Belt is still moderately heavy. Liquid lime-sulphur
has apparently given only fairly good results in controlling
scales. The control is excellent in experimental orchards where
lubricating -oil emulsions were used.
S. B. Eracker (June 1): Extensive spraying campaigns at
Whitewater and Rochester seem to have nearly eliminated the
: San Jose scale. Infestation is slight at the remaining three or
four infestation centers. Spread in a park at LaCrosse caused a
hew thorough treatment.
OYSTER-SHELL SCALE (Lepidosaphes ulmi L.)
Massachusetts A. I. Bourne (June 23): The oyster-shell scale young made their
appearance about the 30th of May to the first of June. We find
there was considerable evidence of winterkilling, so that the
pest was much reduced in numbers, particularly in this immediate
region (Amherst) and is present in about normal numbers.
North
eaaolina
Georgia
Wisconsin
New York C. R. Crosby and assistants: This scale was quite prevalent
throughout Ontario County. In Genesee County no heavy infestation
was found, while in Orleans County it was not bad except in
unsprayed orchards.
Indiana J. J. Davis (June 15): The banded oyster-shell scale began hatching
at Ea Fayette on June 3» &&& "by June ID they had all hatched?
in fact most of them hatched within three or four days after the
first young were noticed.
Wisconsin U. C, Boss (May 25): This insect has been reported as attacking
the apple at Oshkosh.
HALE-WINGED GEOMETER (Phigalia titea Cramer)
New York C. R. Crosby and assistants: In Rockland County the half-winged
geometer is still very plentiful, feeding slightly on the young
trees. Caterpillars ofoseveral sizes are common on young apple
- 126 -
trees throughout the county. They attack the fruit as well as
the foliage, eating off the skin of the young apples, at Spring
Valley.
APPLE FLEA-T.7EEVIL ( Or chest es nallicornis Say)
Pennsylvania S. T7. Erost 4nd Anthony Berg (June 8): The apple fl<?&—we evil
has "been found mining the leaves ex the apple -at Morgant own ,
W. Va. , This insect was present in considerable numbers.
FLEA-BEETLES (Systena taeniata Say and S. hudsonias Forst.)
Pennsylvania S. 1. Frost and E. M. Craighead (June 8): Two flea-beetles have
been found serious on apple seedlings in Adams County; Systena
taeniata Say and Systena hudsonias Forst. The former was by far
the more numerous.
IMBRICATED SNOUT -BEETLE (Epicaerus imbricatus Say)
Illinois "57. P. Flint (June 19): Imbricated snout- beetles have been sent
in with reports of damage to corn, strawberries, soy beans, and
apple buds. This insect has been reported from Jersey, Green,
Henry, Marshall, Putnam, Mercer, and Johnson Counties. Beetles
have been sent in from other points in southern, central, and
northern Illinois.
Nebraska M. H. Swenk (June 15): Tn eastern Otoe County a young orchard
chiefly of apple trees was largely defoliated during the second
week in June by the imbricated snout-beetle.
NEtf YORK "EEVIL (Ithyccrus novehoracensis Forst.)
Illinois J. H. Bigger (June l6): This insect cut two-thirds of the twigs
off of 20-acres of 2 and 3 -year-old trees in Calhoun County.
EUROPEAN RED SPIDER (Paratetranychus pilosus 0. & F. )
Massachusetts A. I. Bourne (June 23): Under date of June 18, Mr. E. R. Farrar
feports that mites on apple trees and some ornamentals were
increasing to a considerable extent, owing to the long period
of hot dry weather, so that they were causing a marked shading off
in color of foliage. Heavy rains in the vicinity of Lincoln about
the 15th or l6th checked this condition to some extent.
New York C. R. Crosby and assistants: This pest is not bad in Orleans
County; abundant in several orchards, but not serious to date in
Genesee County, while in Ontario County they are found in most
orchards and are quite abundant where thDDUugh spraying has not
been done. In Chautauqua County some have been found occasionally
but not in serious abundance. They are quite prevalent in Dutchess
County but no special injury has been reported.

PEAR
PEAR-LEAP BLISTER-MITE (Eriophyes pyri Pgst. )
New York C, R. Crosby and assistants: In Ulster County this mite was
found common, though serious in hut one orchard, while in
Monroe County, moderate damage was noted in unsprayed orchard.
It has been found quite generally on the water sprouts and suckers
in pear orchards, and prevalent generally hut only of minor
importance la Genesee County. In Oswego County it is quite
prevalent in unsprayed orchards throughout the county. It is
unusually abundant in Orleans County on pears this year, very
had in general . It has "been found in quit era few orchards
in Ontario County, and is quite prevalent in one pear "block
in the nursery at Honeoye Sails,
Washington A» L, Meland* er (May 29): In an orchard half way between
Steptoe ana Cashup, which had apple and pear trees intermixed,
the apple. leaves were all badly blistered by the blister- mite
while one of the pear leaves showed the work of this mite,
I believe our western apple blister mite has been identified
by Bureau experts as the same species as the pear-leaf blister-
mite.
CALIFORNIA PEAR SAWFLY (Gymnonycbus californicus Marlatt)
Washington A. L. Melander (May 29): Yesterday in driving from Spokane
I stopped at an orchard halfway between Steptoe and Cashup
and noted pear leaves with circular holes, evidently the work
°f Gymnonychus cal if or ni The young larvae were eating
their way around and around in the circular openings. We have
no record of this insect in Washington, so I thought you would
be interested,
PEAR MIDlE (Contarinia pyrivora Riley)
New York C, R. Crosby and assistants: 10 to 15 per cent injury was observed
in one orchard in Genesee County. One orchard at LeRoy has been
found infested with this pest, attacking the Eawrence variety
particularly. It was also found at Bethany, In ulster County
they have left the pears and are in the soil. This insect is
increasing -in importance this year.
M. C Leonard (May 29): Young pearcfruits badly infested with
larvae were received from P. L. Huested. (April 23)=: This insect
was reported as abundant on this date on Clappfs Favorite at
Blauvelt,
PEACH
ORIENTAL FRUIT-MOTH (Laspeyresia molesta Busck )
Connecticut Philip Garman (June 21): Only a few twigs are infested.
- 128 -
Virginia L. A. Steatms (June 21): For the first time this insect is
found in most of the larger commercial orchards in this section;
the first brood of worms are now full grown; their feeding has
resulted in widespread and serious twig injury, and considerable
damage to late ripening varieties of peach is anticipated.
GREEN PEACH APHID (Myzus perelcae Sulz.)
New York C. R» Crosby and assistants: The green psach aphid is unusually
abundant this year on the growing tips in Orleans County, In
Wayne County it has been noticed in various parts of the county,
but does not seem to be abundant enough to be serious,
Delaware C. 0» Houghton (May 15): This insect was reported attacking
peach at Newark, and Bridgeville, and cere abundant thaa in an
average year.
CHERRY
CHERRY APHID (Myzus cerasi Eab . )
Massachusetts A, I. Bourne (June 23): The black cherry aphid proves to be
very abundant on sweet cherries.
New York C, R* Crosby and assistants: This aphid is abundant in
Ontario County on one or twoejreet cherry trees, but no complaints
have been received. In Orleans County, theybwere plentiful
very early, but largely destroyed by Syrphu§ maggots and ladybird
beetles, while in Ulster County, they were numerous in general,
except in five orchards where early aphid sprays were used.
In Genesee County they are only found slightly, at LeRoy.
Idaho
Idaho
D. B. Whelan and Claude TTakeland (June S): Undersides of
terminal leaves of cherry at Wendall were covered w ith aphids.
Cherry trees in Boise were observed badly infested with aphids,
many winged.
|>EAR SLUG (Caliroa cerftfti L. )
Don B. Whelan (May 28): Eggs of the pear slug were abundant
on cherry and pear leaves. None observed have hatched yet.
PLUM
PLUM CURCULIO (Conotrachelus nenuphar Hbst.)
Massachusetts A. Ii Bourne (June 23): The curculio is found generally
distributed throughout all the blocks, particularly serious
on the plums of all varieties, and along the borders of all
the apple blocks, especially those in grass. In Bristol
County reports indicate that the plum cucculio is very abundant
^
- 129 -
in that section and observers are finding a considerable amount
of fruit scarring, the result of their work. Mr. A. R. Jenks
of West Acton, in Middlesex County, reports in his region that
cunculio damage seems to "be very severe.
Connecticut W. H. Barrow (June ): Some orchards have secuted very good control
"by following up the calyx spray soon with two more applications.
Hew York C. R. Crosby and assistants: Plum curculio is generally serious
over the fruit section of the State. Damage on pears and apples
in some cases quite as serious as on plums, Infestations running
as high as kO per cent in Genesee County and 50 to 60 per cent
in Dutchess County have been recorded.
Delaware C. 0. Houghton (May 15): A moderate amount of injury to various
fruits is appearing here and elsewhere in the State.
R. W. Leiby: The first curculio secured by jarring peach trees
at Aberdeen, March 26, was one day earlier than in 1922. Emergence
has been erratic. Prospects are for a light infestation for
1923, ovring to severe winter conditions and a comparatively small
number going into hibernation last fall because of a successful
control campaign waged throughout the season of 1928. The first
egg was secured this season in the insectary on April lU, and
and the first egg-wras found in the field on April 19*
Oliver I. Snapp (June 20): The adults of the first generation
began to emerge from the soil June 7. 1923» They were leaving
in numbers for 10 days following. It is believed that only the
Georgia Bells and Elbertas will be attacked by second-generation
larvae this year. It has been found that the newly emerged beetles
feed for a period of 10 days or two weeks before egg deposition,
and this will give the Hiley, an important commercial variety
of peach in Georgia, time to mature and be harvested before being
attacked by the second brood. Parasites of C_.> nenuphar are
unusually numerous this year. Triaspis curculionis is the most
common parasite in Georgia. Some parasite boxes containing C.
nenuphar larvae show parasitism of over lU per cent.
S. B. Pracker (June 15) : The curculio is very bad in places in
Dane County, aid is also reported from Jackson County, Madison,
and Black River Palls. It is more abundant as compared xvith an
average year.
T. H. Jones (May 22): The first adults issued today from "drops"
collected on April 2U and kept in a jar in a well ventilated
insectary.
PLUM APHID (Hysteroneura setariae Thos.)
Massachusetts A. I. Bourne (June 23): The plum aphid is; present in considerable
numbers, particularly on a few of our Burbank trees.

New Mexico
New York
0. G. Babcock (May 9):
the "black plum aphid.
Many complaints have come in regarding
W. E. Emery (May 28): These aphids are doing quite a" tit .of damage,
causing the plums to turn yellow and fall.
RASPBERRY
A T/EBWORM (Cr ambus sp. )
C. R. Crosby (June U): The larvae eat the smaller shoots off near
the surface "but do not seem to "burrow very deeply. The raspberry
plants were set out in a field plowed this spring. It was an old
meadow.
ROSE SCALE (Aulacaspis rosae Bouche)
Indiana J. J, Davis (June 20): This scale is very abundant in many sections
of southern Indiana, in many cases being largely responsible for
the death of shoots before fruit matures.
RASPBERRY FRUITV70RM (Byturus unicolor Say)
Connecticut B. H. Ualden (June 23) : Injury is largely confined to the St.
Regis in ITew Haven County; fully as abundant as in an average year.
New York
New York
Maine
C. R. Crosby and assistants: In Chautauqua County one berry patch
was found badly infested by this pest, which was observed abundantly
in only two locations in Ulster County, though plentiful in general.
It is very abundant and destructive in one patch in Silver Creek,
and at Sodue in Wayne County the beetle '"was injuring over 80 per
cent of the blossom clusters in one planting*
RASPBERRY SAWFLY (Monophadnoides rubi Harris )
C. R. Crosby and assistants: The raspberry sawfly is plentiful
in all plantings in Chautauqua County, considerable damage being
done.
RASPBERRY MAGGOT (Phorbia rubi^ora Coq. )
Mr. J. M. Mosher reports this insect as seeming to attack younger
canes than the cane-borer beetle. In this case the canes are about
18 inches high. The infested canes are quite numerous. Maggots
are still very young.
GRAPE
ROSE CHAFER (Macrodactylus subspinosus Fab.)
Massachusetts A. I. Bourne (June 23): From Middlesex County, E. R. Farrar,
of South Lincoln, reported under date of June 18 that the rose
chafer is present in approximately 10 per cent greater amount
-131-
than is normally the case, and that it "began to make its
appearance in that section about the 15th of the month. The
first rose chafers were seen on the 12th of June and they are
with us in numbata somewhat greater than normal. Several com-
plaints have come in of theii work on young fruit trees as veil
as on roses, grapes, and ornamentals, on which they are normally
found.
Connecticut
New York
!?. E. Britton (June 23): The first beetles were seen on June
10, apparently more abundant than last year.
J- A. Manter (June 22): This insect was found injuring small
apples to quite an extent at Mansfield, being a little more
abundant than in an average year.
E. P. Felt (June 21)
at North Chatham.
This insect is doing considerable injury
C. R. Crosby and assistants: Some injury is generally dis-
tributed in Dutchess County, while in Ulster County the insect

North
Carolina
Ohio
F. Sherman (June 8): This insect occurs throughout the State,
but complaints of serious damage to apple, cherry, grape, etc.
are always from our mountain area exclusively. Two reports on
June 5 indicate it as destructively prevalent in two adjoining
mountain counties, Buncombe and Henderson.
E, W. Mendenhall (June 13): The rose chafer is doing great
damage to grapes, and apple trees, and to cherry tree leaves
and fruit.

GRAPE ROGTWORM (Fidia viticida Walsh )
New York
Michigan
C. R. Crosby and assistants: In vineyards unsprayed last year,
the rootworm is causing serious injury in nearly all parts of the
grape belt, and in three or four vineyards has caused a loss of
20 to 30 per cent of the vines, in Chautauqua County. Typical
foliage injury is showing up considerably in some localities.
R. H» Pettit (June 15): Mr. Harman has just come back with specimens
of the grape blossom midge. He reports from 3 to 5 Per cent damage
all over the vineyards visited and brings back specimens which
proved the identity of the pest. As this is rather a new thing
in Michigan, I am sending you this information. It has been present
in one vineyard in Michigan, for three years but has been kept
down by hand picking until the present season. It therefore bids
fair to add one more to the list of grape troubles in our State,
A WEEVIL (Rhigopsis effracta Lee. )
California California Weekly News Letter, Vol. 5, No. 12 (June 16): Mr.
John P. Coy reports a serious attack by the weevil Rhigopsis
effracta on grapevines. Hb states that it confines its attack
pretty much to the buds and tender growth and has been working
on young grapevines, killing the new growth as fast as it shows v
up, and has destroyed a patch of sweet potatoes. Mr. Coy states
that so far he has not been able to get satisfactory results with
any insetticides.
W. D. Pierce (May J>1): Specimens of Rhigopsis effracta Lee,
a weevil, were sent in by Harry Smith, with the report that they
were damaging the tender growth of grapevines. So far as I know
this is the first charge against this species, which has formerly
been reported as from yucca. The specimens are from San Bernardino
County, and I presume are doing this damage because of the breaking
of new ground. They are probably root weevils.
GRAPE PLUME MCTH (Oxyptilus periscelidactylus Eitch)
Massachusetts A. I. Bourne (June 23): A few clusters pulled together by the
larvae of the grape plume moth have been found through the vineyard,
but this is not at all serious.

numbers. In a few instances they amount to a fraction of 1 per cent.
I found little colonies of females with a family c? young at the tip
of the plant. The Jackson area is partly in bloom, although the pods
in some fields are well formed and the peas half -grown. They expect
to cut in less than ten days for the most pari-. This morning I re-
ceived a letter from the agriculturist for the F. R. Roach Canning Co.

GranS Rapids, in which he reports entirely similar conditions in the
pea canning areas of the western part of the State. He feels that
the hazzard to pea earners has almost passed and I have advised a
policy of watchful waiting with everything ready to dust should
developments warrant dusting. In other words, I think we are going
to get by this year, but we came altogether too near the trouble to
feel easy.
Wisconsin J, E. Dudley (May 28): Aphids are attacking clover and alfalfa in
Columbia and Jefferson Counties. They are probably less abundant
than in the average year, and they are slowly but steadily increasing.

ing melon, cucumber, and squash at Madison. It is less abundant
than usual for this time of year, but the season is quite backward.
Only one or two beetles were seen in May. Seedling cucumbers are
entirely destroyed where no dusts have been applied. Two species
of ground beetles are present. Calcium cyanid dust containing 15,
25, and 50 per cent of calcium cyanid has been remarkably effective
in killing beetles on cucurbits . Even beetles caught in flight die
immediately. There appears to be no question that this dust will be
completely effective against this insect.

ONIONS
ONION THBIPS (Thrips t abaci L.)
Massachusetts A. I. Bourne (June 23): The greater part of the last 10 days of
May and thus far in June h*as been very dry, so that fields and crops
already begin to show some effects of the drought. This has had
another effect in that here in the Valley the onion thrips has begun
to make its appearance much earli. r than we normally expect to find
it and is fast spreading. Finding weather conditions ideal for its
increase, it is in some fields, particularly where seed onions have
been planted near sets, beginning to cause some alarm.
New York H. C.Huckett (June 14): The thrips is infesting onions and. seedling

New York A. G. Newhall (June 9): Injury was first observed during the past
week in Wayne County.
F. H. Bond (June 13): It is not at all general or serious so far
this year in Oswego County. (June 16): Onion maggots were found
on June 13 .
- 145 -
Wisconsin J. E» Dudley, Jr. (June 7): Thrips are attacking onion in parts
of Racine County. They are more abundant in certain sections.
The season is late, there is considerable rain, and the temperature
is below normal. Onions are much smaller than normal and maggots
are developing as rapidly as in a normal season; consequently damage
to small onions is considerably greater than usual.
Illinois Chas . C. Compton (June 12): The onion maggot is much more severe
this year than last. Onions grown for sets are suffering most.
At this time the injury is just beginning to show up in the Chicago
district.

CUTWORMS (Euxoa sp .)
J. J. Davis (June 15): Cutworms were received on June 5 from Akron,
where they were reported as destroying onions on a large scale.
WIREWORMS (Elateridae)
F, H„ Bond (June 18): Considerable injury to onions on a bed of
comparatively new muck was noted June 13 in Oswego County. Wire-
worms were found under plants in many cases, but it is not absolutely
certain that they were the cause.
Fred Maw (May): Do you know of any way to get rid of wireworas?
Pheletes s p. are eating up the onion crop at Meridian.
MISCELLANEOUS FEEDERS
BLACK SWALLOW-TAIL BUTTERFLIES (Paoilio nolvxenes Fab.)
A. G. Newhall (June 18): These butterflies are common on the muck
where celery is grown and injury may, therefore, be expected later

GARDEN WEBWORM (Loxostege similalis Guen.)
Ne$ie F. Howard (June 11): This pest is abundant on sugar beets
and Swiss chard in the Birmingham district.
GREEN FLEA-BEETLE (Disonvcha sp. n.)
R. E. Danfo rth (May 19): The new green flea-beetle with orange
prothorax, Disonvcha sp. n., common on beets and chard, is also
attacking white potatoes and turnip leaves.
SPINACH LEAF-MINER (Pegomvia hvoscvami Pans .)
W, D. Mills (June 9): This insect is becoming rather abundant on
both spinach and beets, and it was also found to a considerable
extent on Rum ex acetosa in Nassau County.

CATERPILLARS
Iowa Carl J.Drake (May 25): I have just received some rhubarb containing
caterpillars tunneling the stalks. Carl Heinrich, of the U. S. Bureau
of Entomology, states that it is a species of Pyralidae (Pyraustinae) ,
but does not know the species.
ROOT-KNOT NEMATODE (Heterodera radicicola ^reef-Mueller)
Nebraska M. H. Swenk (June 15): The ruination of a patch of radishes in
Morrill County by the root-knot nematode was reported during the
middle of June.
CUTWORMS (Noctuidae)
New York A. G. Newhall (June l) : Cutworms are attacking onions and lettuce
at Williamson. Most cutworms are two-thirds grown. They were
first observed near Sodus April 20 of this season. They seem to
be less serious where fall plowing was done last fall or where the
land was thoroughly worked this spring, planting the crop late. The
poison mash bait works best after other food has become less abundant .
For this reason it is most effective after the crop has been thinned
and weeded. Cutworms have been found in one man's lawn doing much
M. D. Leonard and H. Dietrich (June 15): Cutworms are attacking
melons and tomatoes at Appleton. I see a lot of them when planting,
but broadcasting bran, moistened and sprinkled with Paris green, does
the trick.
F. H. Bond (June IS): Cutworms are doing considerable injury to
lettuce, onions, and cabbage on a few farms in Oswego County. They
are found in small numbers on practically all muck land, in most
cases not doing enoughd&aa.g9 to warrant application of poison bait.
Cutworm injury was serious throughout the muck sections last year.
The larvae are nearly mature and little more injury is expected.
Iowa C. N, Ainslie (June 2); Complaints are heard on every hand at Sioux
City of depredations of these pests. gardens, potatoes, and corn
are attacked and injured.
A WEEVIL (Hyperodes hyperodes Deitz .)
California W. D. Pierce (May 31): The note on Listronotus sp. published last
month (Vol. 3, p. 88) refers to this species.
FOUR-LINED PLANT-BUG (Poecilocapsus lineatus Fab.)
New York Roy Latham through M. D. Leonard (June 19): A few occur at Laurel,
L. I., but they ar& very abundant at Calverton, where thousands were
found in headlands of fields feeding on Bidens , Rubus , Ambrosia, and
Rhus, but they seemed to prefer Bidens. They had started working
also on beans near the edge of the field.

FALSE CHINCH BUG (Nysius ericas S chill.)
R. L. Webster (June 15): Reports have come in from Adams and
Mcintosh Counties to the effect that these false chinch bugs were
destroying flax. I can find no records in the literature of such
injury. Nymphs feed on Russian thistle in fields and may be affect-
ing weeds more than the crop.
GARDEN SLUG (Agriolimax Columbian us Gld., Agriolimax agrestis L.,
and A. caj.xf ornicus Cooper)
W. D. Pierce (May 31): Not only is the small garden slug bad here,
but three huge woodland species at least are doing damage to gardens
along creeks. These slugs reach 6 and 7 inches in length and eat
all kinds of garden plants.
SNAIL (Helix aspersa Muller)
W. Dwight Pierce (May 31): Much damage is being done on the Peninsula
from San Bruno to Palo Alto by an imported snail, which was brought
in by Frenchmen to eat. They are spreading rapidly and are very
injurious. They are also at Oakland.
FOWBUG (Porcellio scaber Latr.)
D. W. Pierce (May 31) : Sowbugs , mainly Porcellio scaber Latr., are
very bad here, and in fact all around the Bay, and very destructive
to young plants .
AN APHID (Myzus braggii Gillette)
T. H« Jones (June 4): A correspondent wrote to the experiment
station, complaining of injury by "little green lice" to globe
artichoke. No specimens were sent*
MILLIPEDS (Diploiulus luscus)
R. H, Pettit (May 28): A market gardener at Muskegon has a great
deal of trouble with millipeds in muck. The millipeds were identified
by Dr. Chamberlain at Washington as Diploiulus luscus . a ppecies
introduced long ago from Europe. The gardener has four acres of
muck infested with these millipeds. They do serious injury to
lettuce and celery; cabbage seems to come through with little damage.

BOLL WEEVIL ( Anthonomus grand is Boh.)
North Carolina Franklin Sherman (June 8): Boll weevils have been reported from
the following Counties: Moore, Harnett, Robeson, Scotland, Lenoir,
Cumberland. Mecklenburg, Sampson (central part), and Cabarrus. At
this date (June 7) it is evidently out in all our heavily infested
148 -
sections in~the southeastern half of our cotton area. None have
yet been received from the more northerly part invaded last summer,
i. e., north of an east-and-west line drawn through Raleigh.
R. W. Leiby: The first authentic boll weevil was taken out of
hibernation for season on April 17, and the second on April 24.
Both were found on a canvas frame while jarring for the plum curculio
on peach trees .
Geo. A. Maloney: The boll weevil has been reported as present at:
the following points: Laurinburg, Wadesboro, and Gibson.
South Carolina J. L. Walton (May 18): Reports from the Southern Cotton Oil
Company^ mill managers show that weevils have been found on young
cotton at Dillon, S. C.
Geo. A. Maloney: The boll weevil has been reported as present at
the following points: Bennettsville, Georgetown, Chester, Marion,
Allendale, Sumter, Abbeville, Darlington, and Laurens, from May 12
to May 23, inclusive.
Georgia Geo. A. Maloney: The boll weevil has been reported as present at
the following points: Vienna, Monticello, Fort Gaines, Cordele,
Commerce, and Orangeburg, from May 29 to May 31.
J. L. Walton (June l) : A report from S. Schwarzweiss , cotton ex-
porter, Waynesboro, Ga,, indicates that the weevil is plentiful in
practically all parts of Burke County, Ga.
Florida Geo. A. Maloney (May 29): The boll weevil has been reported as
present at Madison on this date.
Alabama Geo. A. Maloney:' The boll weevil is present at the following points
Clayton, Cpelika, Elba, and Gadsden, on May 29.
Texas M. C. Tanquary (June 15): The percentage of boll weevil success-
fully emerging from hibernation in central Texas indicates a fairly
heavy infestation for the early part of the Season.
F. F. Bondy (May 23): Report indicates a fairly heavy infestation
of the boll weevil at Hearne, Texas.
FALL ARMYWOEM (Laphygma fruginerda S. & A.)
South Carolina J. A. Berly (June 11): The fall armyworm destroyed 6 acres of
cotton and 10 acres of vetch before being checked. It has been
found in three places in this immediate vicinity, in each case
starting on vetch. They were eating holes in the peaches on a
few trees adjacent.

COTTON LEAFWORM ( Alabama argillacea Hoab.)
T. C. Barber (June 14): Worms have appeared in considerable numbers
in several localities, during the past week- The worst infestations
have been observed in the neighborhood of Bio Hondo, but many can be
found near Brownsville. Dusting the plants with calcium arsenate
is being generally done to combat them.
BOLLWORM (Heliothis obsoleta Fab.)
Philip Luginbill (June 15): The caterpillars seriously injured vetch
and when this was cut spread out and attacked adjacent crops, such as
cotton, corn, and cowpeas .
C0WPEA CURCULIO (Chalcodermus aeneus Boh.)
F. Sherman (June 8): This insect was epidemic with us on young
cotton in 1907, but seldom reported since until the last two years,
when it was often mistaken for the boll weevil and also reported on
account of its own injuries to young cotton* Its appearance in
young cotton this year slightly precedes that of the boll weevil.
Mildly epidemic with us now, it is reported from Wayne, Greene, Nash,
Halifax, and Robeson Counties. The correspondence when explicit
indicates that it is confined chiefly to lands which were in peas
the preceding year.
COTTON .APHID ( Aphis gossypii Glov.)
Geo. A. I.'aloney (May 29): Cotton lice have been observed at Vienna.
W. F. Turner (June 23): I am convinced that the main cause of their
abundance was the use of calcium arsenate against the boll weevil.
The lice get dusted with poison, and the main factor in their control,
the Coccinellids , eating them with this frosting, are killed. That
lets the aphids multiply in peace.

FOREST AND SHADE-TREE INSECTS
MISCELLANEOUS FEEDERS
PERIODICAL CICADA (Tibicen septendecim L.)
BROOD XIV (SEVENTEEN- YEAR RACE)
A. I. Bourne (June 23): The 17-year locust has been reported as
appearing in Pocasset (township of Falmouth) in great numbers on
June 12. Most of the territory there has been burned over by a
tremendous wood fire (May 23-26, last) so there is but little under-
growth and no foliage left. The cicadas are hanging from the dead
scrub oaks and charred pine branches in vast numbers. Similar
conditions existed on territory which escaped the ravages of the
fire. So far I have no complete data on this brood, but from my
personal observations its range is from near Monument Beach east
to Sagamore, south to S. Sandwich and west to Pocasset.
R. M. Lupton (June 7): The periodical cicada is very abundant in
scuub oak sections on the central part of Long Island.
Pennsylvania S. Vf. Frost (June 8): Locusts have been emerging in considerable
numbers in A.dams County, but no damage has been noted.
Maryland IV. L. McAtee (May 28): Specimens were sent to me for determination
from Elkridge.
A. L. Quaintance (June 4): I heard yesterday in the wood on tho
back part of my farm a few periodical cicadas. I should judge
there were 10 or 12 of these insects within hearing distance.

Tirginia Rex Hunt (June 26^: Observed a few adults and cast skins early in
June in the Brushland near my home in Clarendon.
Dhio R. S. McKay (May 30): These insects are very numerous , covering a
small area in Batavia and Stonelick Townships in Clermont County.
Adults were first noticed May 27.
T. H. Parks (June 23): Locusts have appeared in the southern
counties in swarms larger than expected. Lawrence County has the
most* Swarms are reported to date from Gallia, Scioto, Pike, Ross,
Adams, Brown, Clermont, and Hamilton Counties. The survey is not
yet complete.
Tennessee G. M. Bentley (June 13): Brood XH is occurring as scheduled. In
some sections we are having reports of serious injury being done to
peaches and apples .
Lee M. Hut chins (June 15): Heavy injury has been reported from
locusts on newly cleared ground at Kingston, particularly on trees
in their second and third year in the orchard; the shoots 1/4 to
1/2 inch in diameter are partially or completely broken off.
Indiana J. J. Davis (June 13): The locust is reported as abundant in a grove
four or five miles north of La Fayette on June 13. Infestation is
not yet confirmed. (June 15): Investigated today. Evidence of
presence but no locusts found. A fanrer reports that they were not
extremely abundant.
BROOD XXII (THIRTEEN- YEAR RACE)
Mississippi Seo. H. Kent (May 26): The 1923 brood of the periodical cicada
appeared in Franklin County in large numbers about the earlier part
of May. I have taken notes on this insect for 52 years past as
follows: 1871, 1884, 1897, 1910 and now in 1923. Stragglers will
appear again in 1924 as they have in 1872, 1885, 1898, and 1911, and
have formed, eventually, a new brood of some considerable scientific
value and importance.
R. W. Harned (June 7): We have now received specimens of the period-
ical cicada or 13-year locust, belonging to Brood XXII, from each of
the counties where it had previously been reported, that is, Adams,
Amite, Claiborne, Franklin, Jefferson, and Wilkinson Counties. Besides
that we have received specimens from three other counties, Warren,
Hinds , and Utica.
Louisiana T. H. Jones (June 14): The first 1923 adults of this brood of which
we have record were taken on May 8 at a point in Livingston Parish
directly across the Amite River from Magnolia (East Baton Rouge Parish) ,
Later on during May and early June colonies were noted a few miles to
the north and east of Baton Rouge (East Baton Rouge Parish). Prof.
0. W. Rosewall of the Louisiana State University has specimens as
follows: Deerford (E. Baton Rouge Parish); Hope Villa( Ascension
Parish); Jackson (E. Feliciana Parish). I also have a verbal report,
without specimens, of the appearance of the species at St. Francis ville
-152-
(West Feliciana Parish) . In connection with the appearance of the
cicada near Baton Rouge, we have heard it reported that the insect
appears every sewen years and that blackberry fruits are poisonous
when it appears because the cicadas lay their eggs in the fruit.
GIPSY MOTH (Porthetria dispar L.)
Massachusetts A. I. Bourne (June 23): The gips y moth is not proving as abundant
as usual, and its egg masses in the vicinity of East Wareham have
apparently been very heavily parasitized. Owing to heavy rains
about the 15th or 16th, Mr. Farrar states that he has seen scarcely
one of the gipsy moth this season, indicating that the infestation
is very light indeed. Mr. A. R. Jenks of West Acton, in Middlesex
County, reports in his region that gipsy moth work is almost negligible,
BROWN-TAIL MOTH (Euproctis chrvsorrhoea L.)
Massachusetts A. I. Bourne (June 23): A. R. Jenks of West Acton, in Middlesex
County, reports the brown-tail moth work almost negligible. Mr.
Farrar states that he has seen scarcely a brown-tail caterpillar
this season, owing to heavy rains about the 15th or 16th, indicating
that the infestation is very light indeed.

sprayed apple orchards in different parts of Louisa County.
Wisconsin S. B. Fracker (June 15): Cankerworms are less injurious to elm
than in 1921 and 1922 in southeastern counties; they are worse from
Madison to Spring Green.
FOREST TENT CATERPILLAR (Malacosoma disstria Huebn.)
Massachusetts A. I. Bourne (June 23): From southern Worcester County a report
was received that to some extent the forest tent caterpillars were
mucl? more abundant than last season and, in fact, thicker than for
many years all through the section of Framingham .
Connecticut J. A. Manter (June 22): The tent caterpillar is now in the pupa
stage and is on the increase at Mansfield.
New York L. J . W. Jones (June 15): This insect is attacking maples at
Bainbridge. It is probably increasing. The damage cannot be
computed but apparently is slight here. A few wasplike parasites

creased number of parasites.
R. L. Webster (June 5): First report from Kenmare in the north-
western part of the State.
Washington News (June ll): Nature is coming to the aid of western
Oregon, whose caterpillar invasion science could not halt. Parasitic
flies are laying eggs in the caterpillar fur. The eggs hatch and
the parasites gnaw. The caterpillar squirms, staggers, curls up,
and dies. Millions of dead worms are in the outskirts of Corvallis
and on the road to the Yq.quina Valley, whence they came. In a few
days all will be dead and a good rain will revegetate the country,
which they stripped of greenery.
A. L. Lovett (June 15): Worms reported stopping trains are tent
caterpillars, which are mostly gone.
SPANWCRM (Ennomus subsignarius Huebn.)
G. E. Smith (June 9): The caterpillars are very abundant and have
partly defoliated entire woods at the present time in Orleans County.
