OUTSTANDING ENTOMOLOGICAL FEATURESS FOR JUNE, 1922.


In eastern and southern Nebraska a Hessian fly infestation has developed which is heavy enough to menace seriously the next sowing of wheat. In
Kansas the second brood is manifesting itself much more seriously than was expected. In places as high as 25 per cent of the straw has fallen. The fly w~as discovered this year for the f irst time in Cheyenne County. This extends the fly'-infested ter'ritory in Kansas -to the Colorado State line.

Early in the month several local green-bug outbreaks developed in
southern !=.d eastern Nebraska. In Kansas this insect has seriously daraged
oats over the entire State, and all spring grain has suffered heavy losses in Colorado, especially in the Arkansas Valley.

As wits to be expected from the comparatively mild winter and the infestations which developed last year, the chinch bug has put in an appearance in the north-central States. About the middle of June it was reported from
southern Michigan, late in 1tay it was observed in large numbers in South Dakota, where it appeared in damaging numbers last year for the first tire in the history of the State. It has also been reported as serious for thB first time in about 20 years in the southeastern corner of Iowa in Lee County. The late emergence of the bugs, in the region of heaviest infestation last year, induced ther to oviposit on young corn, and as a result the infestation of this crop so early in the season has already proved very disastrous. Reports of heavy egg laying by overwintored bugs in young corn have been received from Illinois and Kansas.

The bollworm is again appearing in heavy infestations in the louth and being picked up in the northern produce markets on southern raised truck.

Grasshoppers are emerging in serious numbers in the Upper Peninsul& of Michigan, western Nebraska, southwestern Ohio, and quite generally over Colorado.

The alfalfa weevil has very decidedly increased in the Reno district in Nevada near the California State line, several square miles of newly infested territory having been discovered this spring.

The clover-root curculic (Sitona hispidulus Fab.) has been found seriously damaging soybeans in Illinois, Indiana, and Missouri.

The rosy apple aphid is reported as unusually numerous in the New England and Middle Atlantic States as far north as Virginia and westward to Ohio.

The apple-tree tent caterpillar is very numerous in New England and Now York while farther south this pest is noticeably less numerous than usual.

The pear-leaf blister mite has appreciably increased in abundance in
Oregon and in the White Salmon District of \7ashington. In the Yakima Valley of the latter State it was reported for the first time as an apple pest last
year. It also appears to be quite serious in western M.isouri.

CEREAL AND FORAGE- CROP I NSEC TS



HESSIAN FLY (Bw-tohr~ +astructo Say)

Nesbraska M. H. Swank (June 15). "Local losses, due to the attack
of the Hessian fly, have bacono apparer~t as lrar-erst aprr-:vahss. Early in Ju-ne corisidarab:le whe- at _-,- northwast-?;tn Fluas C&.tybegan to show results of injury by tk-his past.

The cool, backward s y :- has favored H36sian fly devlo,=ent and in many z%;.. L%_, s his post is an actual menace to th3 grain ,,o be sowe~i th-is fall."

Kansas E. G-. Yally (Jun-, 16), "A very light infestation occurs
over tha eastern third of the State."

JW. McColloch (JUr3 30). 17Thile very little i.nfe3station by th3 f7'3' could be fr-ilc. duTg OarL.:; :pring the re has been a un.rked jincreaso in tVe2paa~e of the3 second
brood. In some cases as high as 2b par cent of th3 stalks are gngdom.-rn. It i's of particul.lar interest to note that infae,;ed *vhaat was received from Cheyenne Coirnty in nortlhrvast'-r Kansas. This is th-3 first time the fLly has bde:n taken in this Counity, our previous western limit be~lrg in th3 northeastern corner of' Logan County. This means that practically the entire acre~; deote. t wheat in this State, is subject to outbreaks of the Hessian


Oregon L. P. Rockwood (June 13). 'Infestation severe over a
limitod Frea in the Pleasant Hill s:?ction of Lane County and at Independence in Polk County. As a rule this season the earlier sown fall wheat is less infested than late-sowsn fall wheat, probably because the former made better growth before the advent of the unusually long dormrant season. There are no signs 'of th3 second h4riig brood as yet."

GREATER.WEAT-STE MAGGOT (Meromyza americana Fitch)

Nebraska M. H. Swenk (June 15). The greater wheat-stem
maggot has not appeared in its usual abundance
this year. Injury to grass heads, in some cases up to half of the heads in a field, was reported
late in May from Frontier County, and anattack
on young corn plants in Thayer County was noted
t ward the middle of June."

Missouri A. C. Burrill (June 15). "In Cass, Shelby, Scluyler,
and Caldwell Counties this insect is now very common.
I judge that the epidemic is very nearly State-wide
and the infestation ryns from 1 to 5 per cent."

Kansas E. G. Kelly (June 16). "A light infestation occurs over
the eastern half of the State in wheat and rye,"

Oregon L. P. Rockwodd (June 13). "The spring brood of
Mromyvza Bn_1air Backer was out about May 20 in the
Willamette Valley."

WHEAT MIDGE (Contarinia tticij Kirby)

Missouri L. Kasean (June 10), "County Agent of St. Louis
County reports that 30 per cent of more of the wheat
is infested with the wheat midge."

GREEN BUG (Toxontera graminum Rond.)

Nebraska M. H. Swenk (June 15). "The cool, backward spring
was probably responsible for several local outbreaks
of the green bug. The first reports ware received
June 9 from Harlan County, five days later oat fields in Webster County were infested, and on June 10 fields in Sarpy County were found with the heads covered with
green bugs.'

Kansas E. G. Kelly (May 27). "This pest has become unusually
abundant during the past few weeks in southeastern and south-central Kansas. (June 5). "This post has
become very abundant on oats in the northeastern quarter
of the State where the damage is estimated to be about
10 per cent." (June 20) "Oats have been damaged over
the entire State."

Colorado C. P. Gillette (June 21). "The green bug has caused
heavy losses of spring grain, including wheat, oats, and bar'~ly, at least in the lower Arkansas Ealley in
this State and more especially in the dry farming
sections in the extreme southeastern counties."








109. IM (H l. ,. t ritici Fitch)

Illinois W. P. Flint (Jun3 17). "Much fallen straw in wheat fields
in the central part of the State, due to damage by this
insect. One field showed 99 per cent infestation and many
fields over 50:epr cent."

PALE WESTRN CUTwORM (Porosasrotis orthogonia Morr.)

North
Dakota R. L. Webst3r (June 20). "Dam~age to corn is now very
evident, though this insect seems to be less serious this
year than last."

CORN

CHINCH BUG (Blissus leuconterus Say)

Michigan R. H. Pattit (June 14). "I have just received a letter
from County Agent at Adrian, stating that chinch bugs are
doing some damage right now in barley fields. This is
the first recod of the year of chinch-bug work."

Indiana J. J. Davis (June 16). "Spreading abundance of this pest
seems to be greatest in the northern half of the State.
Probably no marked increase ovir last year in the southwestern corner of the State."

Illinois W. P. Flint (May 17). "Owing to lateness of bugs moving
out of winter quarters and the fact that many fields at that time had a heavy growth of grass, large numbers of
eggs were deposited, resulting in a heavy infestation of
young corn. Many fields hav- already beeon seriously
damaged. First nymphs were observed in southern Illinois
May 27 and in central Illinois May 29. The pest is in
sufficient numbers to causc serious damage as far north
as Peoria and Adams Counties."

IowA. F. A. F3nton (June 8). "Chinch bugs have appeared for the
first time in about twenty years in several places in Lee
County." (June 12) "A wir from county agent in Lee County states that twelve r2ports of serious injury have come in.
I visited this County June 6 ond found chinch bugs damaging
corn which was not over two inches high." (June 14) "Mr.
Butcher writes from Lee County to the effect that chinch bugs are already present in corn and that there is going
to be a hard fight."

South
Dakota A. L. Ford and L. M. Gable (May 25). "Last year chinch
bugs appeared in South DAkota in damaging numbers for the
first time in the history of the State Those bugs apparently
wintered successfully and at present are working in large
numbers on the winter grain."












Missouri A. C.Burrill (Juno 17). "The chinch bug is much loss serious
than usual. A h3avy downfall of rain about throes woiks ago
so 3ms to have wipsd out an outbreak that was very threatening."

Mississippi R, W. Earned (Jun3 17). 7Vore complaints than usual wero
riceivad during the past two months in regard to tho chinch
bug. Most of th-oss cmplaints, hoW,3Vor, came from tho Delta
section of th3 Stati, Th5 abundance of theso insects is
probably duo to th-1 fa ct thA we had an exceedingly dry sumer
and fall during 1921.n

Kansas E. G. Killy (Jun 16). "Eggs 4jr2 now hatching. Many oggs
w,'ra deposited on corn this yeair, which is an uni",l condition
in this State. 'Wh3at cutting is now under way and bugs are moving into th.- corn. No serious dwAmgo has been reported
as yit. Howiv~r. corn is unusually small for this season
of thi yelar -ind dA=ge may be 3Xpectad."

J. W. McColloch (June 20). "Ther3 is a large amount of injury
to young corn and sorghum by chinch bugs throughout tho oaste.rn
third of the Stat3. This injury is rather unusual for this
tima of the' y3.ar. The3 cool weather which prev.ilod during the
oarly spring hold chinch bugs in the-ir winter qu"rtors and
gavo, wheat a heavy growth. Chinch bugs, on moving from winter
quarters, settled on young corn and sorghum and in many Casos
havi ruined ntir3 fields. Young bugs arc hatching "t tho
present tixne in largo numbe-rs."t

BOILW0BFU (Mliothis obsolota Fib.)

Massachusatts H. T. Fornald (June 22). "A larva zent in from Bittsfi3ld,
where it was found on string bans that had boon shipped
in from th3 South, w-is r3eared -ind provedA to b3 the corn
carwprm.tt

Illinois W. P. Flint (June 17). "Th3 first -idult was taken at Urbana
op1 Juno 13."

Tanne3ssea S. Marcovitch (June 8). "Found egg.,s aind larvae on toin-.to~s
in se-veril localities in wist3rn Tinnossee. Som3 worms a
alre.adyv full grown and consider,"blo injury is showing up.
Sivezr, truck' rs arei spraying and the results arei being
watched."

Alabama W. E. Hinds (June 19). "Th3 ro-istigg earworm or cotton
bollworm app3ears unusu-Ily aibundant and dama.ge, to corn a4nd cotton
is likely to be more- thin usual. TorrAtoe8 Arl now suffe-ring
from the- attack of this ap-cios."

TWO-STRIPED GRASSBOPPER (Melanop2 s bivittatus Say)

Nebraska M. H. Swenk (Jrne 15). "Grasshoppers began hathhing in
western Nebraska during the last week in May and have continued hatching numerously in many localities. By this time they are mostly hatched and the larger ones
about one-third grown. So far they have been most
threatening to crops in Scottsb!lff, Morrill, and Sheridan
Counties where active preparations are being made to
fight them."

FD-LEGGED GRASSHOPPER (Melanzplus femoratus Burrm.)

Michigan R. H. Pettit (June 8). "Grasshoppers were appearing in
the upper peninsula in enormous numbers. I have reason to
believe they are Melanoplus femoratus."

CLEAR-WINGED GRASSHOPPER (Camnula I2.12Aida Scudd.)

Oregon B. B. Fulton (June 8). "All stages of grasshoppers are now
present at Tule Lake in Klamath County, even a few adults.
They are hatching in the strips of tule and moving into
the grain crops, devouring every blade as they go." (June 10) "At Fort Klamath eggs are just hatching in small areas which
are several inches higher than the general level. Many of the spots are still surrounded by water. Within these
small areas the hoppers are thick enough to darken the ground."

GRASSHOPPERS (Undetermined sp.)

Iowa F. D. Butcher (June 15). "Grasshoppers were found on May
20 in Cass and Montgomery Counties in sufficient numbers to
warrant their being watched closely."

Colorado C. P. Gillette (June 21). "A large number of complaints of
grasshopper injuries are coming in from beth irrigated and
grazing areas in the State. The Department is putting out a
concentrated grasshopper poison in which crude arsenic is used with banana oil in place of lemons or oranges, which
is meeting with good success and for which we are having a
large call."

EUROPEAN CORN-BORER ( jgausta nubilali, Huebn.)

Massachusetts H. A. Mostrom (June 10). "Vany larvae wintered over in stubble.
Eggs were in abundance on the under side of dock leaves during
the latter half of May. There is every indication that the
serious damage of last year will be repeated this season."

percentage of kill has been approximately the same as that
secured by nicotine sulphate in the spray solution. Vie
found, however, that the action of the dust is much quicker.
W7e have also used derris in both the liquid and powder forms against red bugs and other insects. The solution worked as
effectively as nicotine sulphate but we did not succeed in
getting control with the powder form when used in solution."

1921). "The most outstanding plant trouble that has come to
our notice the past few years is the coconut scale which
practically ruined the entire coconut industry of the neighboring island of Saipan. It was necessary for one to observe this outbreak at its height in order to appreciate fully the
possible destructive character of this pest. Recently a letter
was received from the Superintendent of Agriculture of Suva, Fiji,
mentioning the presence in Fiji of Asnidiotus transDarens (=destruct,;







S128

and stating that a chalcid parasite had been introduced to control
this scale. The authoriti3s in Sa,)an claim that the scale is now beh:ng pa:ePs+ied. Rcoertly I oblained material and forwarded it to the. Department fr icntification. The question
of a contrcl parasite for this Fcale is one of very great importance to the coconut industry throughout the Orient."

Mississippi F. H. Chittenden (Wonthly letter, Bur. of Ent. No. 97). "To
date the new potato weevil is found in the Counties of Stone
and Harrison in southern Mississippi by inspectors of the
Mississippi State Plant Board. The infested area covers a
strip of territory about 14 miles long and 5 miles wide."

CLAVATE TORTOISE BFETLE (Deloyala clavata Fab.)

New York C. R. Crosby (May 31). "This insect was found eating tomato
foliage in a garden at Ithaca."

(Editorial note: Mr. H. S. Barber has recorded in Proc. Ent.
Soc. 'ash., Volume XVIII, that this species has been reported
as an enemy of the white potato as far back as 1870. Dr. 7. D.
Pierce found the species in Texas, breeding on Physalis cornuta.
Both the larvae and adults are known to attack potato and bittersweet in Massachusetts. Dr. F. H. Chittenden has specimens collected on horse nettle (Solanum nigrum) at Glen Echo, Md.
This species is also found in New Lexico, Arizona, Louisiana,
Kansas, Missouri, Nebraska, Michigan, Kentucky, Massachusetts,
Connecticut, Maryland, and Florida. The records from Nebraska,
Kansas, and Missouri are uncertain.)

POTATO APHID (Yacrosiphum solanifolii Ashm.)

Pennsylvania S. 17. Frost (June 14). "This aphid has not been found abundant
on potatoes this summer."

New Jersey L. D. Leonard (June 19). "This insect is comparatively scarce
at Pompton this year. Only a few specimens have been found
and these were parasitized."







131

Virginia W. H. White (June 6). "The potato aphid has caused serious
damage to potatoes on the eastern shore of Virginia. ':E
e" :. p : ,'c y atendent in the vicinity of Onley and aZ;tville. The fungous disease tq:q4parently checking the spread of this pest to a certain e::te'nt. The reet heavy
riins hav also been a factor in control. The p!inciple
damage was to the terminal shoots which were in may instances co :etely killed." (June 8) "The potato aphid haes caused
se~oz.s damage in the Norfolk section. At the preoznt time
a fungous disease is preventing its further spread."

Ca'o .inat A. N. Conrladi (June 1). "County agent of Charleston County
reports that this insect is exceptionally abundant this year
Where he estimates that the yield has been cut 30 per cent
by this insect."

POTATO LEAFHOPPER (Fagg mali LeB.)

New Jersey M. D. Leonard (June 19). "Adults of this leafhopper are now
fairly aoundant about Pompton. They were first observed the
early part of this month. No nymphs as yet or any sign of
hopperburn."

Iowa F. A. Fenton (June 20). "The potato leafhopper appeared in Lee
County June 5 and in central Iowa June 12. The first spray was put on in southern Iowa Counties the week of June 12 and
is being put on in central Iowa theyweek of June 19."

TARNISHED PLANT-BUG (_LEus pratensis L.)

Nebraska M. H. Swenk (June 15). 'Tarly in June a potato field in
Richardson County became so heavily infested with the tarnished
plant-bug that many of the plants wilted down and died, with
occasionally a heavy loss in a field."

POTATO-TUBER WO RM (Phthorimaea onerculella Zell.)

Mississippi R. W. Harned (June 17). "Recently larvae and pupae were
collected from the stems of potato plants at Mceenry. These
were determined by Dr. F. H. Chittenden as possibly the potatotuber moth. This is the first record we have of this insect
occurring in Mississippi and may eventually prove to be some
other species."

MITES (Rhizolyphus sp.)

Nebraska M. H. Swenk. "Shortly after the middle of Eay a field of early
Ohio potatoes in Buffalo County became seriously attacked by mites to such an extent that about 20 per cent of the plants
were badly hurt, the mites penetrating far up the stems of the plants from deep pits on the sides of the roots. Other fields
of early Ohios in the vicinity were similarly but less seriously
affected while none of this injury was observed on Cobblers."















CABBAGE MAGGOT (Hylemvia brassicae Bouche)

Massachusetts H. A. Mostrom (June 10). "This insect is quite serious in
Essex County, some farmers losing rather a heavy percentage
of the plants set out. Many of the larvae have already
pup at ed."

Now York C. R. Crosby and assistants. "Late in May and early in June
serious injury to cabbage was reported from Chautauqua, M!onroo,
and Nassau Counties."

Colorado C. P. Gillette (June 21). "During my residence of more than
thirty years in Colorado I have never seen or heard of a
cabbage plant attacked by the cabbage maggot until recently
when two complaints came to my office, one accompanied by a good-sized package of cabbage plants from a market near
Denver that were ruined by this insect."

STRIPED FLEA-BEETLE (Phyllotreta vittata Fab.)

New York C. R. Crosby and assistants. "Late in May those flea-beetles
were reported as doing serious damage in Nassau County."

STRAV7BERRY

STR7BERRY 7TEVIL (Anthonomus signatus Say)

damage."

Barvpeithes pellucidus Boh.

New York E. P. Felt (June 23). "'1r. L. V. Jones and M r. R. F. Horsey
have both brought to my attention this weevil. It occurred
only in small numbers at Rochester and Genova."

STRAVBEIRY CR0VN-BORER (Tyloderma frwariae Riley)

Tennessee S. Marcovitch (June 10). "The strawberry crowvn-borer is a
well known pest of old strawberry fields but in Tennessee
it was found very numerous in the mother plants set out this spring and interfering with the production of runners. This condition is becoming common in Tennessee and it is becoming
difficult to obtain a stand, due to the work of this borer.
Full grown larvae can now be found."











133
SPITTLE INSFCTE (Cercopidae)

Oregon A. L. Lovett. "This season they are strikingly abundant on
both strawberries and cane fruits. They occur mostly about the crown of strawberries and about the base of the canes on
loganberries. No really serious injury is apparent as yet
in spite of their extraordinary numbers."

ASPARAGUS

ASPARAGUS BEETLE (Crioceris asparazi L.)

Massachusetts J. B. Boston (June 10). "This insect is worse than ever.
Chickens do good work but spraying is unsatisfactory. The
crop is seriously injured in Barnstable County."

H. A. Mostrom ("lay 15). "Larvae are present and doing damage
in unsprayed fields in Essex County."

New York C. R. Crosby and assistants. "The comon asparagus beetle
is serious in Chautauqua, Orange, and Nassau Counties."

Ohio H. A. Gossard (ITay 26). "Asparagus beetle larvae were appearing at Chillicothe during the third week of M{ay."

Colorado C. P. Gillette (June 21). "This insect was introduced in
gardens at Boulder several years ago but only within the
last year or two have complaints begun to core to this office
of its appearance in gardens about Denver. The insect ray
be considered as established in the Denver-Boulder section no*."

BEANS

MFXICAN BEAN BEETLE (Eiachna corrurta I'uls.)

Tennessee J. A. Kennedy (June 22). "This insect is eating up garden
beans, entirely destroying a field in a few days at Dayton."

Mfiss 11. Adsmend (June 19). "A new kind of weevil that has

H. V!. Andrews (June 16). "The Mexican bean beetle is doin5 a great deal of damage at Sparta and in adjoining counties."

Alabama W7. E. Hinds (June 19). "The Vexican bean beetle is increasing
very rapidly and the damage is likely to equal that of 19 Z1 when it amounted to 75 or 80 per cent of the normal yield of
table beans in the Birmingham area."










134Oolorado C. P. Gillette (June 21). "The Mexican bean beetle began
to make its appearance in the Fort Collins district, according
to our observations, on June 14 this year and was becoming
fairly corzon by the 17th. It is a little later than usual
this season."

PEAS

PEA !PHID (Illinoia pisi Kalt)

Massachusetts J. B. Boston (June 10). "Generally bad in Barnstable County
where spraying with nicotine sulphate was resorted to."

Connecticut 7. E. Britton (June 24). "Appeared in several fields about
New Haven in the middle of June and did considerable darage."

Now York H. C. Odell (M1ay 1). "Severely infested fields found yesterday
in Nassau County." (May 27). "The pea aphid is doing very
severe injui'y in many fields in Nassau County."

New Jersey M. D. Leonard (June 19). "Present in small numbers about
Pompton."

Delaware G. A. Fly (June 1). "This insect cut the factory pea crop
one-half in sore cases about Greenwood. In others the crop
was a total failure."

Maryland E. N. Cory (May 16). "An outbreak of this insect on canning
peas has developed at Betterton."

Indiana H. F. Dietz (June 19). "The pea aphid has been very abundant
on peas this spring."

CLOVER ROOT-BORER (H1astinus obscurus Marsh.)

Oregon A. L. Lovett (June 2). "Commercial plantings of garden peas
in a small locality in Miarion County were seriously attacked.
This outbreak was undoubtedly due to adjacent fields of
abandoned clover which were very heavily infested with this
weevil."

CUCI3 BER

STRIPED CUCUM1BER BEETLE (Diabrotica vittata Fab.)

Massachusetts H. T. Fernald (June 22). "The cucumber beetle is now badly
riddling the plants."

Connecticut M. P. Zappe (June 24). "This insect is much more numerous

ONION I'AGCOT (Hvlemvia antiqua Yeig.)

Connecticut J. A. Enter (June 22). "This insect is doing much Carnage in
gardens about Stors."

New York M. C. Hammond (M[ay 27). "A light infestation is manifesting
itself in Orange County."

Indiana J. J. Davis (June 16). "The onion maggot is quite abundant
in the State wherever onions are grown."

Oregon A. L. Lovett (June 2). "As a whole this insect is much less
abundant than usual. In demonstration plots where the
British Columbia method of using cull onions as a lure for
the adult flies was employed fiold infestation was slight.
Cull and volunteer onions of the proper type showed from 50 to 500 eggs, and counts running as high as 437 maggots in a cull onion were mado, many showing over 200 maggots.
The idea of cull onions in onion maggot control is good.
Our technique this year is faulty, as the majority of the culls were planted too shallow to be the best lure. The
majority of the generation of onion maggots were nearly mature larvae on June 2; probably 4 per cent had pupated
and adult flies and eggs were not uncommon."

ONION TH-IPS (Thrins tabaci Lind.)

New York G. E. Smith (M ay 17). "Onion thrips injury was observed on
onions on the Genesee-Orleans muck tract."

Visconsin S. B. Fracker (May 20). "Unusual damage occurred about Pay 1 in the Green Bay district. The infestation was reduced by
weather conditions and the injury was mostly outgrown by
'set' onions."

These trees are elven years pld. In the sumer of 1920 our
cavnts gave an average of 15 to 20 infested buds per tree.
&aly in the spring of 1921 several bushels of infested buds werd gathered and burned. In late June a heavy application of 9-T sulphur dust was given. These treatments materially
reduced the amount of infestation. In April of the present
year the tre3s were again given a thorough inspection and as many infested buds as could be found were destroyed, On Ab
5th of June 100 trees were inspected and only 20 infested
buds were found. On this data the first adult was taken from

BOXWOOD LEAF-11INER Wonarthropalpus buxi Labou.)

New York E. P. Felt (June 23). "The box leaf-miner is well established
on Long island and in southern Westchester County, occurring
in enormous numbers on groups of box and causing serious
injury. The flies began to emerge about the middle of May, most of them coming out in immense swarms within a few days,
though a few remained in the larval stage until June 16.
The best control at Port Chester was secured by using 6
pounds of molasses to 50 gallons of water and making applications
every other day."

New Jersey Richard Hiizing (June 1). "This pest is proving quite serious
to boxwood at Eatontown and Elberon."

Pennsylvania J. K. Primmn (ay 11). "This is the worst pest of box where
it occurs and is now invading nurseries and private estates in Montgomery County which were free from it two years ago.
Adults began to emerge !ay 1 in 1921 and on May 8 this year.
The dwarf box, Buxus suffructicosa, is nearly immune from
attack, but other varieties may be heavily infested. It is
now quite generally distributed throughout Philadelphia,
Bucks, Montgomery, Chester, and Delaware Counties of this
Stato."

AZALEA

AZALEA LACEBUG (Stenhanitis pvrioides Scott)

.Pennsylvania J. K. Prirnm (.:ay 27). "Marked browning of leaves is noticeable at this early date on hardy azaleas. In 1921 many azaleas were defoliated in southeastern Pennsylvania due
to this insect. Specimens of the evergreen varieties
succumb to this attack when not sprayed in time. Nicotine
sulphate, 1 part, to 500 parts water is an effective control."

LILAC

LILAC BORER (Podosesia svringae Harris)

New York E. P. Felt. "Ur. R. E. Horsey reports that the lilat borer
(Trochilium denudatum) is so serious in the lilac collection in Rochester Parks that it is necessary to go over the bushes
carefully to remove breakage ."

ANTS (Fonrmicidae)

Michigan R. H. Pettit (June 8). "Ants are very troublesome here this
year, both in houses and in lawns. 7e have discovered a
new departure in the preparation of ant poison. Often ant
poison made of tartar emetic and honey, 1 part to 19, has
failed because the tartar emetic settles to the b)otton,
especially if the honey has been heated too ruch. 7'e stir the poison into the honey that is showing a tendency towards
crystallizing, now and then add quite a bit of granulated sugar, stirring it in cold to aid crystalization. Honey
that is prepared cold in this way and stirred in thoroughly
holds the tartar emetic in suspension. Failures in the
past have come from the poison settling down either in the
container or in the dishes in which the poison has been
offered to the ants."

FLEAS (Siphonaptera)

Indiana H. F. Dietz (June 19). "Fleas have been unusually abundant
in private dwellings. An outbroak in Indianapolis proved
to be the cat and dog flea Cr.nocenhalus canis and an outbreak in Greenwood, the human flea, Pulex irritans."
