THE MORE IMPORTANT RECORDS FOR MARCH
Throughout the upper Great Plains region grasshopper eggs are still in
good condition and but very little winter mortality has been reported. In
the more southern States of Oklahoma, Texas, Utah, and Arizona, and in south-
ern California as high as 10 percent of the eggs have already hatched.
Mormon crickets started hatching in mid-January in Nevada. By the end
of February they were hatching in parts of Montana, and in March we received
reports of hatching from Wyoming, Utah, and Washington.
May beetles were observed at lights in Mississippi and Louisiana dur-
ing the latter half of March. It is estima-ited that 400,000 acres of wheat
have been destroyed by white grubs in south-central Kansas. Heavy damage is
also reported in parts of Oklahoma.
The army cutworm is becoming numerous in parts of Kansas and Oklahoma.
Heavy flights of armyworm moths were observed late in l.V'rch in Vir-
ginia, Indiana, Missouri, and Oklahoma.
Observations late in March indicate that the chinch bug has passed
the winter very successfully in Illinois, Iowa, and Oklahoma. In the latter
State rather heavy flights were observed on March 25 during a period of high
A local outbreak of green bug was observed near Stillwater, Okla.,
and in the southwestern part of the State. This insect was reported as do-
ing considerable dinmnoge in northwestern Texas.
Light infestations of hessian fly are recorded from Missouri and
Corn ear worm eggs were found in central Texas during the third week
in March. This insect is also recorded as having passed the winter suc-
cessfully on Long Island, N. Y., and in Utah.
The pea aphid was reported as present in alfalfa during the last week
in March in Virginia, Louisiana, Oklahoma, Texas, and Washington.

B U L L E T I N
Overwintering larvae of codling moth were beginning to pupate in
Georgia and Delaware during the third week in March. This insect seems to
-----...have passed the winter successfully over most of the country.
The first pupa of oriental fruit moth was observed in Georgia on
March 19. In Delaware, 28 percent of the larvae had transformed by March 23.
Plum curculio adults began to appear in the Fort Valley section of
Georgia on March 4 and in marauding numbers by the middle of the month. They
were beginning to appear in numbers by 'arch 23 in Albemarle County, Va.
Green citrus aphid was numerous in central Florida during the first
week in March. By the middle of the month, however, the infestation had sub-
sided, apparently owing to large populations of the Chinese ladybeetle (Leis
dimidiatus F. I
The vegetable weevil was abundant enough in tobacco plant beds in
Georgia and Florida to necessitate control measures. Rather severe damage to
turnips is reported from Mississippi and Louisiana. The weevil was also re-
ported damaging cover crops in southern California.
During the third week in March avery heavy infestation by harlequin
bug was observed on cabbage and mustard in the Chadbourn district of North
Carolina. The first individuals of these insects were observed in the Nor-
folk district of Virginia during the fourth week in the month. This insect
is also reported as quite numerous throughout southeastern Oklahoma.
Father heavy infestations of tobacco flea beetles were reported from
Tennessee during the third week in March. The insect was reported from South
Carolina and Virginia, but little damage has been done.
Very large numbers of male cankerworm moths have been observed in
Illinois, Iowa, Missouri, and Nebraska. Heavy stripping of foliage of apple
trees is reported from Oklahoma and this insect is also recorded as emerging
in Ohio, Pennsylvania, and New Jersey.
The outbreak of Epinotia meritana Heinr., first recorded last year in
the Powell National Forest, Utah, appears to be as heavy, if not heavier,
than it was last year.
A very heavy infestation of sandflies in the vicinity of Savannah,
Ga., was reported this year. It is said to be the most serious outbreak in
the last 5 years.
During the third week in March several specimens of dog ticks were
collected from different localities on Marthas Vineyard Island in Massachusetts.
Cattle grubs are reported as being more abundant than during the last
3 years in Iowa. Dropping of the grubs is somewhat earlier than usual in
Georgia and Missouri.
Buffalo gnats are causing some trouble in parts of Mississippi, al-
though the situation is not as serious as in 1933.
G E N E R A L F .2 E D E R S
Iowa. H. E. Jaques (March 21): Grasshopper eggs seem to be unusually
abundant throughout much of the State, particularly in the southerrn
and western parts.
North Dakota. F. Gray Butcher (March 23): Observations indicate that
eggs have olpritntered with no noticeable injury. 'Many reports of
overwintering nymphs from various sections.
Missouri. L. Haseman (March 24): Recent egg check-ups indicate relative-
ly little winter mortality. We are expecting a very heavy hatch.
Arkansas. R. L. Shotwell (March 28): Melpnoplus. differentialis Thos. is
the dominant species of grasshopper in the northeastern part of
Arkansas. The eggs are in good condition and hatching is expected
to begin about April 20.
Kansas. H. R. Bryson (March 29): Grasshopper eggs are abundant in practi-
cally every section of the State. Observations indicate th.,t they
have overwintered in perfect condition. Eggs dug out of the soil at
Manhattan on March 21 and kept in the laboratory hatched in a few
days. Third-and fourth-instar nymphs of ChrrtoprhJ1-i_ spp. were plenti-
ful in Riley County about the middle of the month.
Oklahoma. H. T. Rainwater (March 23): Farmers attending organization
meetings for grasshopper control at Ardmcre, in Carter County, and
other places reported occurrence of newly hatched grasshoppers on
March 23. This was confirmed in some places by survey observations.
C. F. Stiles (March 25): Recent examinations of eggs in
scattered communities throughout the northeastern and central parts
of the State show that they are in good condition. A few oe
brought into the office and kept at warm temperatures have already
hatched. A smill number of hoppers of the noninjurious species
have also been reported.
B. A. Bieberdorf (March 26): Grasshopper eggs were reported
as hatching in a few isolated places during the week of M-irch 13-19.
Tex-is. R. R. Reppert (March 26): In a few limited and favorably exposed
ire,-s in Navarro County, northeastern Texas, 100 newly hatched rn-,.hs
per square foot were found. (M4rch 29): A survey of Mont-omrery and
Walker Counties, in southeastern Teyis, today indicated hatching
practically completed, with from 5 to 10 nrT-..h per square foot.
Montana. H. B. Mills (March 21): Numerous reports of overwintering nymphs
of C. viridifasciata .Dee. from eastern Montana.
Utah. G. F. Knowlton (March): Reports of grasshoppers hatching in northern
and central Utah were made on March 10, 14, 19, and 22. Grasshopper
nymphs (probably Haldeman's locust (Pardalophora haldemanii Scudd.))
were moderately abundant in rye stubble west of Euroka, in the central
part of the State, on March 11.
Arizona. J. R. Parker (March 29): Not more than 10 percent of the grass-
hopper eggs in Maricopa and Yuma Counties are hatched.. Baiting in
these counties before.April 20 appears .tQb.e unnecessary.
California. J. R. Parker (March 29): Not more than 10-percent of the eggs
in the Imperial Valley are hatched. No hatching north of this valley.
MORMON CRICKET (Anabrus simplex Hald.)
Montana. H. B. Mills (February 26): Mormon crickets began hatching in the
lower Yellowstone Valley on February 26.
Wyoming. Margaret Greenwall (March 24): C. L. Corkins reported that Mormon
crickets were hatching generally in southern exposures over most of
Sheridan County, on the northern border near the central part of the
State, during the entire week beginning March 7.
Utah. C. J. Sorenson (March): These crickets were found hatching in the
western part of the State in Tooele County on..:nrch 11 and in Millard
County on March 15.
Nevada. G. G. Schweis (March 22): The Forest Service.has reported having
observed a hatching of Mormon cricket eggs the middle of January.
Washington. R. Nelson (March 20): The first of the Mormon cricket in
Franklin County has appeared 4 miles north of Pasco.
MTY BEELES (Phyllophaia spp.)
Mississippi. C. Lyle (March 24): F. A. Smith reports that May beetles
were abundant at lights on the streets of McComb the night of March 15.
A correspondent at Picayune, in Pearl River County, reports under date
of March 21 that May;beetles were so numerous in that vicinity as to
defoliate rose bushes and oak md pecan trees.
E. W. Dunnam (March): One. beetle was taken on a window screen
near a light in Leland on March 21 and two were taken at the same
place on March 22.
Louisiana. B. A. Osterberger (March 19): The first flight of June bugs
was noted on March 19. The most numerous species was P. congrua Lec.
The night was;very warm and sultry, the temperature being 730 and the
Kansas. H. R. Bryson (March 29): White grubs have been numerous in gardens.
The adults are just beneath the surface of the soil, ready to fly when
the soil temperature rises.
Virginia. A. M. Woodside (March 23).: Climbing cutworms were fairly common
on peach trees in low spots at Crozet, Albenarle County.
H. G. Walker and L. D. Anderson (M.arch 25): Cut-.,orm eggs were
observed on a spinach leaf at Norfolk on March 10.
Kansas. H. R. Bryson ( Trch 29): The army cutworm ( Chorizagrotis
auxiliaris Grote) has about returned to normal numbers after a scarci-
ty of a few years. They are most numerous in grass plots, but may be
found in alfalfa-fields. Slight injury to seedling beets and spinach
was observed at Manhattan on March 27.
J. R. Horton (March 25): Worms of C. auxiliaries, half grown or
more, were in evidence on winter wheat near Wichita, southeast of the
central part of the State, but were nt numerous.
H. H. Walkden (March 25): Larvae of the army cutworm -are abundant
in pastures in Riley, Clay, and Cloud Counties, northeast of the central
part of the State. This is in marked contrast with 1937, when the
larvae of this species were very scarce. Larvae of the dingy cutworm
(Feltia subgothica Haw.) are abundant in pastures near ,Manhattan,' Riley
County. Small larvae of the clay-backed cut-"or-, (F. igladiaria MIorr.)
are common in areas where little barley is the dominant grass.
Oklahoma. F. A. Fenton (March 29): The army cutworm has been found in
wheat in several widely distributed places in the State, particularly
in Tillnan and Kiowa Counties.
Arizona. C. D. Lebert (March 25): On March 23 some damage by cutworms
was noticed on melons south of Phoenix area. Adults of F. annexa
Treit. were taken in a citrus field on February 4.
BUTTERFLIES AD :10iTHS (Lepidoptera)
Pennsylvania. H. E. Hodgkiss (March 24): At State College on March 22 a
specimen of the mourning-cloak butterfly (Homadryas antiopa (L.)) was
taken and on March 19 Qne specimen of the scallop shell moth
Calocalpe undulata L.) was collected.
Virginia. H. G. Walker rmand L. D. Anderson (March 25): A luna moth
(Tropaea luna L.) was collected on March 23. near Norfolk.
Tennessee. G. M. Bentley (March): The tiger swallowtail (Papilio glaucus
turnus L.) is emerging. One adult was brought: to. this office on the
19th and one on the 21st.
Georgia. T. L. Bissell (March 10): Butterflies of the alfalfa caterpillar
(Eurymus eurytheme Bdv.) are on the wing at Experiment.
Florida. J. R. Watson (March 23): Woolly bears are out in force in some
sections, feeding mostly on Rumex acetosella and other plants and
occasionally doing much damage to melons and young corn.
Missouri. L. Haseman (March 24): Along with male cankerworm moths and an
occasional armyworm and cutworm moth at Columbia, a nmLimber of differ-
ent species of moths came to lighted windows and street lights during
the last few nights. They appear to be noctuids, but there are also
a number of other undetermined species included.
Colorado. C. R. Jones (March 26): Mourning-cloak butterflies are emerging
regularly. Specimens of the adults of Autographa californicrt (Speyer)
have been taken.
SCRAPE FLIES (Tipulidae)
Georgia. T. L. Bissell (March 10): "Perrywinkles," or larvae of a
species of crane fly, are abund-.nt in streams at Experiment. They
are used for fish bait.
Mississippi. E. W. Dunnam (March 25): :.nny large crane flies are present
in the vicinity of Leland. A few have been observed since March 10.
C0.'.I01IT RED SPIDER (Tetranychus telarius L.)
Mississippi. C. Lyle (March 24): H. Gladney reports under dnte of
I.-trch 22 that he has observed considerable injury to azaleas,
camellias, -jnd arborvitae in Jackson County. Cape-jasmine leaves
showing injury by these mites were received from Issaquena County
on March 23, and a correspondent at Biloxi, in Harrison County, sent
camellia leaves damaged by them to this office on March 21.
E. W. Dunnan*(March 24): The red spider was found d&oaging
cotton plants in a greenhouse at Stoneville.
Louisiana. B. A. Osterberger .(March .19): These spiders have been very
numerous on flowering sweet ,nc and have caused. a yellowing of the
Missouri and Kansas. H. Baker (March 23): There has been but little mortal-
ity of hibernating red spiders on apple trees, therefore greater numbers
of healthy specimens can be found on apple trees in northeastern Kinsas
and northwestern Missouri than ever before at this season of the year
under this writer's observation.
CEREAL AND FORAGE- CROP I IT SECTS
WHEAT AITD OTHER SMALL GRAINS
ARIMYWOBM (Cirrhis uni-puncta Haw.)
Virginia. H. G. Walker and L. D. Anderson (March 25): Rather large
numbers of arm%-worm moths wero observed flying around lights on the
evenings of March 23- and 214 in Princess Anne County.
Indiana. P. Luginbill (':irch 23): For several days armnyworm moths have
been noticed flying about La ayette and vicinity. Thsy were first
noticed on March 20 and 21. Hundreds of them were observed feeding
on pussy willow on the University grounds. For the last several days
we have had strong southerly winds and possibly they have been blown
up from the south. The temperature has also been favorable for
flights. On March 22 it was 77 F.
Missouri. L. Haserman (March 24): The early season flight of moths has
begun around Columbus, although they haven't becn abundant. The
moths do not seen to be worn by long flight, therefore it is possible
that they are emerging here.
Oklahoma. F. A. Fenton (March 28): C. unipuncta has been found in wheat
in several widely distributed places, in Tillman and Kiowa Counties,
part i cularly.
CHVTCH BUG (Blissus leucopterus Say)
Illinois. W. P. Flint (March 22): Examinations made during the last
month continue to show a very high p percent of survival for the
Iowa. C. J. Drake (March'25): The chinch bug survey now in progress
shows that the winter mortality during 1937-39 has'been considerably
lower than during the last 4 or 5 years. Threatening" populations
of overwintering bugs occur in most of the counties in the southern
third of the State. The infestation is apparently more spotted in
the eastern half of the State.
H. E. Jaques (March 21); In the southeastern part of the State
chinch bugs are fairly abundant.
Oklahoma. R. G. Dahms (March 2e): There was a rather heavy flight of
chinch bugs from winter quarters to small.grains on March 25, when
the temperature reached 82 F. Only a very few bugs had migrated
prior to that date, although the temperature reached 85 on March 20
and 21. (Reported from the State Field Station at Lawton, Comanche
Co an-y;. southwestern Okla.)
GREEN BUG (Toxoptera graminum Rond.)
Oklahoma. C. F. Stiles (March ;25); A local outbreak of this pest was ob-
served 10 miles southeast of Stillwater, in Payne County. The spots
range in area from a few square feet to 20. Some winged forms were
observed. Ladybeetle larvae are very numerous rand under favorable
conditions should check the outbreak.
R. G. Dahms (March 26): The green bug has done considerable
damage in a few wheatfields in the southwestern part of the State.
Texas. F. L. Thomas (March 21): Green bugs were reported as doing con-
siderable damage to wheat in Hale, Floyd, and Fisher Counties in
northwestern Texas, on March 18.
HESSIAIT..FLY (Phytophaga destructor Say)
:,issouri. E. T. Jones (March): Survey of select fields in five south
western counties revealed infestation in 33 percent of the fields
examined. Infestations ranged from 8 to 18 percent, with low in-
tensity. Greatest infestation was- found in Greene County, where 86
percent of overwintering larvae had pupated on March 16.
Kansas. J. R. Horton (March 10): An unusually mild winter start ed de-
velopment of the hessian fly during the first half of February, as
indicated by a little pupation and emergence. Examinations up to
February 18, when interrupted by snow and colder weather, showed
about 1.5 percent living pupae and about 1.5 percent emergence. On
February 18-19 snow fell, covering the ground to a depth of 9 inches
and finally disappearing on February 27. No damage was done to the
fly, unless to the negligible percentage that had passed beyond the
E. T. Jones (March): Survey of the infestation of select fields in
10 southeastern Kansas counties was made on March 12-16. Light infes-
tations, ranging from 2 to 20 percent, with low puparia intensity,
were found in 50 percent of the fields. Highest infestations were
found in Geary County where, on March 18, larvae were found to have
wintered in good condition. On March 15,66 percent had pupated,
about 2 weeks earlier than usual. Although it is possible for a
second spring brood to build up a strong. infestation, only light,
spotted infestations are indicated at this time.
.WHEAT WHITE GRUB (Phylplohaga lanceolata Say)
Kansas. H. R. Bryson (March 29): P. lanceolata has been destructive in
a number of counties in the State. 'The population apparently has
been building up during the last few years. The area of damage has
gradually extended northward. The northernmost limit of injury
occurred at Glasco, Cloud County, on March 25. E. G. Kelly estimates
that approximately 400,000 acres of wheat has been devastated. Most
of this injury has been on land that has been cropped continuously
to wheat for 4 or 5 years. The area most affected lies in the south-
central part of the State, the maximum amount of injury being in
Oklahoma. R. G. Dahms (March 26): This pest is very abundant in some
wheatfields. In a heavily infested field in Comanche County, in
southwestern Oklahoma, an average of 25 grubs per square yard were
found. The weather has been so favorable for wheat growth that very
little wheat has been killed by the grubs in the last 2 or 3 weeks.
G. A. Bieberdorf (March 26): In the wheat-gro-ing sections the
wheat white grub has been doing;considerable damage during the past
winter. The heaviest damage appears to be in Grant, Alfalfa, and Kay
Counties, on the northern border in the central part of the State.
F. A. Fenton (March 2g): The recent favorable weather for wheat
growth has stopped the damage by P. lanceolata, inasmuch as the wheat
plants have now developed root systems large enough to withstand con-
Arizona. E. E. Russell (March 28): Since March 17, with mean temperature
at 57.2 F., Say's stinkbug (Chlorochroa sayi Stal ) has occurred in
greater numbers than common on mature wild mustard (Sisrmbrium irio)
which has been permitted to grow as a cover crop among young citrus
in the Citrus Belt east of Me;n. When first observed these bugs were
uniformly dark olive green in aolor, indicating that they had recent-
ly ener;ed from winter quarters. Egg development in the ovaries of
the females when first observed was scant, but at present are nearly
fully developed. Little, if any, oviposition has occurred in the
field. Considerable gregariousness has been observed, particularly
on the sunny side of cluxps of heavy mustard with south and east ex-
posure, where from 15 to 30 bugs have frequently been collected by
striking the opposite side of the mustard clump over a standard swoep--
ing bag. An average of 0.146 bug per sweep hae been taken by
ordinary sweeping methods. A total of 959 adults have been examined
showing 55 percent of the total number collected were- females. The
tachinid parasite Gqmnosoma fuliginosa Desv. is present in reason-
ably small numbers.
Texas. F. L. Thomas (March 21): An unknown mite, larger than the red
spider, caused local damage to oats in Hood, Bosque, and Denton
Counties the latter part of January and in February. Investigations
showed that the infestation occurred only on land where oats had
been planted continuously for several years.
CORN EAR WORM (Heliothis obsoleta F.)
New York. L. A. Carruth (March 22): Conditions on Long Island seem
favorable for the survival of the corn ear worm pupae. The natural
mortality of the pupae during the winter months is probably between
95 and 99 percent, but the survival of even a few individuals is
sufficient to insure serious infestations during the following
season. During the spring of 1937 live pupae were found on Long
Island and reared to adults. From present indications, this situ-
ation will apparently be repeated during the spring of 1938.
Texas. F. L. Thomas (March 21): Eggs have been found in alfalfa in
Falls County, central Texas, although no emergence of adults has
yet occurred in Brazos County. Very strong evidence has been ob-
tained this year indicating that the moths spread rapidly over
Utah. H. E. Dorst (March l14): A recovery of approximately 65 percent
of the pupae has been obtained this spring from overwintering cages
that successfully transferred from larvae last fall. A-recovery of
approximately 50 percent of the pupae were obtained in unplowed corn-
SOUTHWESTERN CORN BORER (Diatraea grandiosella Dyar)
Texas. F. L. Thomas (March 21)': This insect was found to have extended
its range east to Wilbarger County and southeast to Taylor County,
according to the survey last fall. It has been distributed through-
out the Panhandle for several years.
ALFALFA WEEVIL (H.rpera postica Gyll.)
Utah. G. F. Knowlton (March l14): An adult weevil was observed to be
active in an alfalfa field at Riverside, in northern'Utah.
California. A. E. Michelbacher (March 22): The average number of alfal-
fa weevil larvae collected per 100 sweeps of an insect net for differ-
ent fields in the San Joaquin Valley on March l14 ranged from 6 to 442,
in the San Francisco Bay area on March 21 ranged from 2 to 198, -vhile
on the same date the range at Pleaston was from 1 to 27. Parasitiza-
tion of large alfalfa weevil larvae by Bathrploctos curculionis Thos.
in the different fields in the San Joaquin Valley cn Febr'ary 24
ranged from less than 1 percent to 2 percent, but since that time has
increased considerably. Parasitization in the San Francisco Bay area
on March 8 was 88 percent.
PEA APHID (Illinoia pisi Kltb.)
Virginia. H. G. W7-alker and L. D. Anderson (March 25): Pea aphids are be-
coming rather abundant in alfalfa fields at Norfolk and a few winded
forms have b,--en collected in pea fields.
Louisiana. C. 0. Eddy (March): These aphids have been common throu-'hout
the' State during the month of March .... ,
Ol0lahoma. R. G. Dah.is (March 26): The pea aphid is abundant in many
fields of alfalfa in southwestern Oklahoma.
Texas. F. L. Thomas archrh 21): Plant lice are reported to be causing
severe damage to alfalfa in Collingsworth County, in northwestern
Washin!ton. R. D. Eichlmann (March 4): Greyn alfalfa at 11.3 7`1ull-i,
barely over 1 inch tall, yields as many as four aihids per sweep of
an insect net. More than a third of these are innature forms, several
of which have wing pads. Many aphids were found on bottom-land al-
falfa last fall. Aphids gave birth to young at Pull'-i. all wint,3r.
PLANT BUGS (Hemiptera)
Utah. G. F. Knovlton (March 14): In northern Utah in alfalfa fields and
on roadside wee"s Ly;7us elisus hesperus Knight is active and adults of
Aallia sanguinolenta Provey. are abunean t.
TmR---COrilEFD ALFALFA HOPPER (Stictoce-hala festinma Say)
Louisiana. L. 0. Ellisor (..March): Nynphs are beinnin- to hatch at Baton
CLOVER LEAF j!-T VIL (Hypera 'unctata F.)
Illinois. W. P. Flint (:.:arch 22): This weevil is appearing in -much more
than normal numbers in the clover fiel@dc in th,'. central part of tho
State. Apparently the mild winters of 1936-37 and 1937-3g are re-
sponsible for the very high survival. It is already ragging
clover and alfalfa in many fields.
California. A. E. MIichelbacher (March 22): Most of the larvae collected
on March 8 in the San Joaquin Valley were dead. It appeared that a
fungus disease was causing this mortality.
SUGARCANE BORER (Diatraea saccharalis F.)
Louisiana. B. A.. Osterborger (March 17): A few borers have been found
in the pupal state. No eggs have been found.
E. K. Bynum, W. E. Haley, and L. J. Charpentier (March): The
examination of cane trash on top of the soil in overwintering ex-
periments in the southern part of the sugar section revealed that
13 percent of the larvae had' pupated by March 2 and by March 15 the
percentage had increased to 50. The first pupa was found on February 9.
On March 21,4 eg- clusters, with an average of 26 fertile eggs per
cluster, were found at Houma 'in' 1 man-hour.
SUGARCAITE BEETLE (Euetheola ruiiceps Lec.)
Louisiana. 3. A. Osterberger (March 17): This beetle was noticed doing
considerable injury to stubble cane around the Bayou Teche section,
St. Mary Parish. Skunks have done much in the control by digging out
the adults for food. Adults are being collected at lights.
J. W. Ingram (March 10): Injury to sugarcane apperrod in the
vicinity of Franklin early in .ZIrch. On 1 plantation 1,230 beetles
were collected at 3 500-watt trap lights on March 10. Warmer temper-
atures than usual for late February and early March have caused the
beetles to become active earlier than usual.
F R U I T I N S E C T S
SAN JOSE SC.*LLE (Aspidiotus perniciosus Cornst.)
Georgia. T. L. Bissell (March 23): A correspondent at Hawkinsville re-
ports that he finds almost no San Jose scale.
Mississippi. C. Lyle (March 24): Jack Milton, at Jackson, and N. L.
Douglass, at Grenada, report that the San Jose scale is causing
severe damage to unsprayed fruit trees in their districts.
Colorado. C. R. Jones (March 26): Numerous requests have come to this
office for control of this pest,
TARNISHED PLANT BUG (Lygus pratensis L.)
Missouri. L. Haseman (March 24): This bug is on wing, visiting fruit buds
and blossoms literally by the millions throughout central Missouri.
CODLING MOTH (Carpocapsa pomonella L.)
New York. D. W. Hamilton (March 26): Notwithstanding the lower -tempera-
tures this year in Poughkeepsie, Dutchess County (-22 F., as com-
pared to h4 in previous years), larval mortality under bands appears
to be low. Snow covered the ground over longer periods than in the
winter of 1936-37, which may have caused more larvae to be destroyed
by birds. While the percentage of infested fruit was somewhat lo-'er
in this region in 1937 than it was in 1936, it should be remembered
that the crop was unusually large. At this time it is estimated
that the overwintering larvae per tree in most orchards .is about the
same as it was last spring.
Delaware. L. A. Stearns (March 23): The season is unusually early and
the apples are well advanced. Early varieties are in full delayed
dormant stage. Pupation of overwintered larvae is 1 percent. In
1937 transformation did not begin until between April 16 and 26.
Georgia. C. H. Alden (March 24).: Overwintering larvae are beginning to
pupate at Cornelia. About 25 percent of the larvae are dead and
appear to have been killed by a fungus.
Wisconsin. C. L. Fluke (1March 31): The mortality of overwintering larvae
was low and practically none was found dead in orchards in Cr'wford
County. More larvae went into winter quarters than have been ob-
served for several years, indicating a large first brood of moths in
Missouri and Kansas. H. Baker (March 23): Recent observations in orchards
in northeastern Kansas and northwestern Missouri indicate that larvae
came through the mild, open winter with a minimum of mortality fmd
that they are unusually abundant. Several growers have noted the fact
that birds were relatively scarce in orchards during the winter.
Kansas. H. R. Bryson (March 29): Larvae of the codling moth were reported
by R. L. Parker to be abundant during the winter in Doniphan County.
Mortality is low.
EASTERN TINT CATERPILLAR (Malacosoma americana F.)
New York. J. A. Evans (March): Egg masses of the apple tree tent cater-
pillar brought into a warm room on March 29 started hatching that day.
Pennsylvania. H. E. Hodgkiss (March 24): Eggs were not as abundant as they
have been the last 3 years, as observed in a survey on March 14 to 16.
Virginia.: M. P.. Jones (.'.rch 31): The eastern tent caterpillar is feeding
on wild cherry near Fort Myer, Arlington County.
North Carolina. W. A. Thomas (March 6): The eggs began hatching at Chad-
bourn the-first of March, before any foliage had developed on wild
cherry. The tents are much more abundant this season than last.
Georgia. 0. I. Snapp (March 24): The first larvae of the eastern tent
caterpillar were observed on February 25 in a peach tree near Fort
Valley, central Georgia. Theso larvae were from.j inch to inch
long on that date. The infestation to March 24 is not greater than
that of an average year.
T. L. Bissell (March 17): Tent caterpillars are just starting
their webs in wild cherry at Experiment. (March 23): A correspondent

little damage was observed, however.
Mississippi. J. G. Hester (March 24): A number of colonies of this in-
sect on wild cherry in the vicinity of State College has been ob-
served during the last few weeks.
Arkansas. W. J. Baer (March 10): Hatching has just begun and a few
caterpillars have emerged from about half of the egg masses. The
species will be common but not very abundant, as judged by the number
of egg masses.
APPLE APHIDS (Aphiidae)
Connecticut. P. Garman (March 23): Eggs of Anuraphis roseus Baker and
Aphis poml Deg. are much more abundant than they were last year, and
occur in large numbers' in. -anny orchards throughout the State. Few
New York. J. A. Evans (March): Gr.in aphids (Rhopalosiphum prunifoliae
Fitch) were observed for the first time in the college orchard at
Ithaca on March 29. Last year they did not make'their appearance
until April 26. 1 1
Pennsylvania. H. E. Hodgkiss (March 24): Aphid eggs were not abundant in
Luzerne, Columbia, and Lycoming Counties on March 14 to 16. On March

grain aphid (R. prunifoliae) are just beginning to hatch at Rid&-e-
Virginia. A. M. Woodside (March 21): The rosy apple aphid (A. roseus)
began hatching in the vicinity of Staunton on March l1 or 19. They
are not abundant but there may be enough in some orchards to cause
damage. Eggs of the appte grin aphid began hatching on March 16 or
Mississippi. C. Lyle (March 24): F. A. Smith reports that there was a
medium infestation of Eriosoma lanigerumCn (Hausm.) on apple trees in
Tate County on March 19 and D. W. Grimes observed this species on
apple at Sallis, in Attala County, on Fobruary 25.
Missouri. L. Hascman (March 24): The eggs of the apple plant lice are
beginning to hatch throughout central Missouri. The species does
not show evidence of being very abundant.

PLUM CURCULIO ('Oonotrachelus nenuphar Hbst.)
Virginia. A. M. Woodside (March 23): Plum curculios are fairly common
along the edges of poach orchards in the Crozet section of Albemarle
County. This is the earliest record of their entering the orchard in
Georgia. C. H. Alden (March 21): The first hibernating beetles were caught
today by jarring peach trees at Cornelia. Last year the first beetles
were caught on April 13. This season is about 3 weeks ahead of 1937.
T. L. Bissell (March 22): A peach grower at Hampton reports a
large number of these pests jarred from peach trees on March 21, but
none has been found at Experiment. (March 26): Curculios are coning
from hibernation in lar:;e numbers and growers have been spraying for
more than a week in Spalding and Lamar Counties. The emergence is
heavier than expected, considering the very light crop of peaches last
0. I. Snapp (March 22): Adults began to appear from hibernation
on March 4 at Fort Valley, about 4 days after full bloom. They were
appearing in numbers on March 15, when three-fourths of the petals had
dropped, and they had reached the center of the orchards in numbers by
March 22. An average of 3.6 beetles per tree were caught in one
orchard on March 15, but the general infestation is not believed to
be heavier than that of an average year. Er-s wore forming in the
bodies of some of the females caught on March 10 and there were na-
ture eggs in the bodies of all females caught on March 15. (March 28):
Larvae one-fourth grown were found in Elberta peaches today. Infesta-
tion about normal.
PEAR PSYLLA (Psyllia pyricola Foerst.)
New York. J. A. Evans (Mlarch): A number of pear psylla eggs had been
laid by March 29.
Connecticut. E. P. Felt (March 24): Ovipcsition by the pear p.sylla has
RUSTY PLUM APHID (Hy.steroneura setariae Thos.)
Mississippi. C. Lyle .(LMarch 24): Plum twigs- heavily infested were received
from Tupelo, in Lee County, on March 19. It is reported that plum
trees in Aberdeen are heavily infested with lice that probably belong
to this species.
THISTLE APHID (Anuraphis cardui L.)
Idaho. R. W. Haegele (March 2): The thistle aphid was found hatching on
prune in southwestern Idaho early in March mnd most of the e;-& hatched
in the warmer districts on this date. The infestation seems general
and indications are that control measures will be necessary to prevent
severe damage. The situation is similar to previous ones w.-hen heavy
infestations of this aphid on prunes have been. observed in springs
following unusually mild winters. The winter was one of the mildest
GRAkPE LEAFHOPPER (Erythroneura comes Say)

on a ranch west of Phoenix on March 10.
WALIUT CATERPILLAR (Datana integerrina G. & R.)
Missouri. L. Haseman (March 23): In recent diggings in the vicinity of
walnut trees that were completely stripped last fall little evidence
of overwintering pupae have been seen, indicating that in spite of the
terrible infestation last fall we will not have an unusually heavy
GREEN CITRUS APHID (Aphis spir-ecola Patch)
Florida. H. Spencer (:.irch 24): These aphids were numerous on oran-e
an.i grapefruit trees around Haines City, in Polk County, central
Florida, the first week in March. The outbreak was subsiding on
March 15, when the Orlund-o district and the Okeechobee -roves near
Port Mrwvaca were becoming infested. In g-neral over the State the
infestation is rather spotted and less intense than in 1937. Around
Orlando the Chinese ladybeetle (Leis dimidiatus F.) is appearing in
lar:.or numbers than in previous years and is the most important con-
trolling factor. It was observed feeding also at floral nectaries
of avocado trees.
COWPEA APHID (Aphis medicaginis Koch)
Arizona. C. D. Lebert (March 25): Several. infestations of the burclover
or cowpea aphid were observed on the terminal growth of citrus in the
Phoenix area.. .

Mississippi. C. Lyle (March 24): Cape-jasmine leaves infested with this
pest have been received from correspondents in Holmes and Lowndes
Counties recently. H. Gladney reports having observed several heavy
infestations on citrus in Jackson and Harrison Counties during the
last few weeks, and Jack Milton states that these insects are abundant
on 0ipe-jasmine in Hinds County.

generally in March, considerably earlier than usual. The infesta-
tion is heavy over most of the State. Much spraying is being done.
California. H. J. Ryan (March 25): The citrus red mite declined some-
what in Los Angeles County in February, but there were still a good
many citrus orchards at the end of the month with infestations heavy
enough to warrant control measures.
SIX-SPOTTED :ITE (Tetranychus sexmaculatus Riley)
Florida. H. Spencer (March 24): This mite is appearing in grapefruit
groves in several citrus-growing sections. Affected leaves show
the characteristic yellow spots.
PIEAPPLE EALYBUG (Pseudococcus brevipes Ckll.)
Florida. H. Spencer (March 24): Golden Abachi pineapple plants, which
have been in the ground 3 years, were found to be heavily infested.
Two species of ants, not yet identified, were associated with these
insects. Many of the plants showed evidence of wilt and could be
pulled out of the ground easily. The variety Red Spanish, nearby,
was less seriously damaged.
DESTRUCTOR SCALE (Aspidiotus destructor Sign.)
Florida. E. W. Berger and Geo. B. Merrill (March 22): A very abundant
build-up of the destructor scale on coconut palms has been observed
at Fort Lauderdale, Broward County. Recent observations, however, re-
veal a high mortality.

Gaorgia. F. S. Chamberlin (March 31): Larvae of the vegetable weevil are
causin. some injury in a largo tobacco plant bed at A:istcrdam, De-
catur County, in southwestern Georgia.
Florida. F. S. Ch-imborlin (March 25): 'Larvae have been found in a con-
siderable number of tobacco plant beds in Gadsden County. Infestn-
tions were sufficiently heavy in a few beds to necessitate control
measures. The insect is also abundant in vegetable gardens.
Mississippi. C. Lyle (March 24): This weevil has attracted considerable
attention in the southern' part- of the State during the last few weeks.
F. A. Smith reports that adults were abundant in the western part of
Pike County on 1'arch 14. The first adults were observed in Harrison
and Jackson Counties on March 15 and rather heavy dIm'--e, especially
to turnips, has been caused. Correspondents in Si:-pson, Scott, Wil-
kinson, Jasper, and Stone Counties- have sent specimens of adult
weevils to this office during the past week, with the infor--:-tion
that they were abundant on and seriously idnaaing potato plants,
Louisiana. C. 0. Eddy (March): Adults were very abundant and destructive
early in March.
California. H. J. Ryan (March 25): The larvae did considerable da-iane in
February to cover crops of mustard and malva in a few citrus orchards
in southern Los Angeles County.
R. E. Campbell (March 31): Many celery fields in southern Los
An;?eles County are' infested; and the stalks show the characteristic
feeding spots. Fror 1 to 8 larvae per bunch are present. If the in-
festation can not be reduced within a month nuch of the celery will

Louisiana. C. E. Smith (1March 26): The larvae started destroyin- youn
corn at Baton Rouge about March 20 and have been increasing. The activ-
ity of this pest is from 3 to 4 weeks earlier than in a normal year,
doubtless because of prevailing mild temperatures since Janiuary 1.

Virginia. H. G. ".7-ilker and L. D. Anderson (March 25): Spinach aehlds are
rather abundant in a great mny fields of early spinach at Norfolk but
are rather scarce in the younger spinach. A fungous disease has killed
from 50 to over 75 percent of the aphids in some of the fields.
STRIWBERRY WEEVIL (Anthonomus signatus Say)'
North Carolina. W. A. Thomas (March 21): The weevils from hibernation
began entering the strawberry fields on March 15 and by March 21
had spread over most of the fields of older berries in the Chadbourne
area. The sudden advent of spring has resulted in a mass emergence
of the weevils from hibernation, causing a sudden infestation to de-
velop much earlier than usual.
SUGAR-BEET WI2&EWOiU.I (Limonius californicus Mann.)
California. M. W. Stone (March 23): Considerable damage to sugar beets
in Orange County occurred in March. Because of the thinned-out fields,
two beet growers replanted over half of their total acreage. Counts
made on March 18 showed an average of 1 larva per foot of row and as
high as 13 larvae attacking a single plant.
BEET LEAFHOPPER (Eutettix tenellus Bak.)

Virginia. W. J. Shoene (March 21): Beetles have emerged in small numbers
at Chatham on March 19.
South Carolina. N. Allen (March 19): Injury to plants in beds has been
very light. This conforms to the results of emergonce in hibernation
cages which begin early in February. The present season has been ab-
normally dry and it appears that this may have affected emergence
Tennessee. L. B. Scott (March 25): At Clarksville :'any plant beds were
found to be infested on March 19. The beetles appeared 2 weeks
earlier than last year and in much greater numbers. Some beds in
which seed had not germinated were found to be infested, indicating
that the plants will be danaged as soon as they appear above ground.
GREEN JUNE BEETLE (Cotinis nitida L.)
South Car6lina. N. Allen (March 19): In making a survey of tobacco beds in
portions of Marion, Horry, Florence, and Williamsburg Counties, it was

collected on corn in the vicinity of Robston on March 11, and five
ioths were collected in a field of alfalfa and clover at Wharton on
March 15. Although no bollworm eggs were found, they were probably
being laid on corn in these localities.
PINK BOLL'VO12. (Pectinophora gossypiella Saund.)
Texas. A. J. ChaliMin ('.'-rch): Several pink bollworm pupae were found in
February in cotton bolls left on the surface of the ground at Presidio.

Texas. F. L. Thomas (March 21): The first flea hopper nymphs have been
found as far north as Falls Counmty, in central T-rs. No adults have
been taken on screen traps in Brazos County.
Texas. K. P. Ewing and R. L. McGarr (i-.rch): N-.mphs hatched from over-
winterin flea hopper egg's in hibernation c,:eos 2t Port Lavaca on
February 12. On the same date first- and second-instar rnymhs were

croton during the week of March 5. This is the earliest we have ever
found adults in eastern Texas.
J. C. Gaines (March). Three adults and several nymphs were col-
lected on flight screens at College Station on March 25. These are
the first adults collected this year at this point.,

numerous complaints are made of the annoyance caused at night by
large numbers of male moths entering dwellings and stores.
Missouri. L. Haseman (March 24): At Columbia during the last week I
have seen more male spring cankerworm moths than I have ever .seen
in any similar length of time in the 30 years I have been connected
with the Department. Apparently we are to have a real tussle with
spring cankerworms in central Missouri this year.
Nebraska. M. H. Swenk (March 21): In the southeastern part of the State
considerable activity of moths of the spring cankerworm was noted
during the period from March 10 to 20.

ceived from Booneville, in Prentiss County, on ,March S.
HOLLY LEAF :.22. (Phtc,.z. ilicicola Loew)
Virginia. C. W7iley (March 21): This pest is apparently more abu rdant
in the Ric hnmond area than usual. A number of requests have bbeen re-
ceivod for control remedies. We have seen a number of individu',Il
trees and at least one hedge heavily infested. Pupation must have
begun about March 1, as all of the 20 or 30 individuals examined on

in all sections from Gainesville south.
ROSE APHID (Macrosiphum rose L.)
Virginia. C. R. Wiley (March 21): This aphid has boen present on roses
in Richmond for 2 months; recent warn weather has apparently stimu-
lated reproduction and now the young rose shoots are very heavily
infested. I noticed a species of syrihid fly hovering over my rose
bushes when I sprayed them March 19. A Danville, Va., nurseorynan
was in the office on March 21 and he was impressed with the abun-
dance of aphids on roses and Japanese barberry in Richmond. He
stated that they were unusually scarce in Danville at that time.
Louisiana. B. A. 0sterb'r,;er (March 16): A green aphid has so seriously
infested rose bushes that many of the roses are not opening normally.

D O M E S T I C A N I M A L S
Florida. B. V. Travis (March 2): The mosquitoes (Anopheles auadrimacu-
latus Say) that have been so abundant around the house all winter
in Tallahassee, are now seen only rarely. (March 17): Still present
but few in number. A. crucians Wied. has been rather numerous around
the outside of the house for the last 2 weeks.
Mississippi. E. W. Dunnam (March 23): "ospuitoes have been noticed at-
tacking people about dusk in the vicinity of Leland. Some have been
observed feeding on the legs of cattle before this time of day.

Oregon. D. C. Mote (March 5): Specimens of mites were sent from North
Bend, -here tey were emerging from a very narrow crack in the wall.
California. R. H. Smith (January 20): This mite presumably has been the
cause of considerable discomfort tb persons'in Los Angeles.
AMERICAN DOG TICK (Dermacentor variabilis Say)
Massachusetts. C. N. Smith (March 25): The first adults were taken this
season on March 21 on Marthas Vineyard Island. One male was found
on my clothing while I was looking for ticks. Five males and five
females were taken from a dog before they had become-.attached, and
several specimens were taken from another dog. Each of the three
lots was taken by a different collector in different localities, all
on.March 21. The temperature reached 60 F.. at this time, the first
day since fall that it has been over 600. No larvae or nymphs have
been collected this spring.
SCREWWORM (Cochliomyia americana C. & P.)
Georgia. 6. L. Brody (M.arch 29): An infested hog near Qui'tman was re-
ported on January 21. A fPirmer also reported another case in his
locality about the middle of February.
Texas. D. C. Parman (,March 25): Screwworm flies (C. americana) were
practically exterminated during the summer of 1937 in the southern
areas in Texas where traps have been operated, at Catarina, Larado,
Hebbronville, Alice, and Three Rivers. In. no catch since August
1937 have there been more than one or two flies in any of these
trips, ncne has been taken since December, and only one in December.
The trappings have indicated that weather conditions have been very
favorable for build-up of C. macellaria. There were 15 quarts of
flies taken at Laredo in January, .practically 87 percent of which
was this species. In February the traps at Laredo, Hebbronville,
and Alice took 21, 26, and 19 quarts of flies, respectively, and
approximately 90 percent of these were C. macellaria.
Arizona. C. C. Deonier (i'tarch 25): Screwworms were taken at Bumble Bee
and Wichenburg during the latter half of January and at Hass-iyrnpa
during the first part of February. They were also taken at Nogales
and Tempe during the latter half nf February. A considerable out-
break of these pests was indicated by examination in the Yuma area
on February 17, infestations being as high there as 20 to 30 percent.
A few cases of screwworns have been reported throughout the area
worked during the winter.
STABLEFLY (Stomoxys calcitrans L.)
Georgia. A. L. Brody (,.o.rch 25): These flies were first noted at Val-
dosta during the first week in February, when from 10 to 15 adults
per animal were seen. The flies were usually found on the lower
half of the legs." This species increased to 25 per animal the middle
of February and in March from 25 to 50 per animal. The steers at the
: farm have been considerably annoyed by stableflies during the last
month. Often it was difficult to drive them from the tall gallberry
bushes among which they stood for the slight protection against the
Mississippi. E. W. Dunnan (March 15): The stablefly has been breeding,
off and on all the winter.
CATTLE GRUBS (Hypoderma spp.)
Georgia. A. L. Brody (March 25): Larvae of the cattle grub (Hypodernma
probably lineata DeVill.) were still appearing- in the backs of steers
during the latter part of February. The last recorded removal was
made on .February 24. The greatest appearance of warbles has been
noted from the second week in November 1937 to the second week in
Iowa. R. W. Wells (March 29): Cattle grubs (H. linetum and H. bovis
Deg.) are more abundant this year than during the preceding 3 yearn,
as judged by examinations made of cattle in the counties of Story,
Boone, Warren, and Clayton. In Warren County all of the 30 larvae
of H. lineatum taken from 3 head of cattle were in the third or
final instar. Apparently no grubs had dropped from these cattle on
March 22, when the examinations were made. In Clayton County on
March 23, 291 grubs were taken frcm cattle and 52 percent of them
were in the second instar. The presence of a few gruribs in the first
instar indicated that not all of the larvae had reached the backs.
IMissouri. L. Hasenan (March 24): Recent investigations on ox warble crn-
trol have revealed the fact that throughout central and north-central
Missouri generally our co-cion warble has been maturing ahead of
schedule. Practically all of the warbles, where the animals were
not treated, have already escaped from the backs of cattle. A few
specimens, not over half-grown, taken during the past wed,-k, seenM to
be individuals of the northern later naturing. species.
HOERi FLY (Haematobia irritans L.)
Georgia. A. L. Brody (March 25): Horn flips were first observed to be
active on February 8, at which time le-s than 10 flies per animal
were noted. The number per animal increased to 50 flies during the
middle of February, and to 15C by the middle of March. It was in-
teresting to note that on all occasions when observations were node
more flies were seen on dark- th.'.n on light-colored anima-ls.
GRLEI1BOTTLE FLIES (Lucilia spp.)
Georain. A. L. Brody (March 29): Five infestations of larvae of Lucilia
spp. were found in artificially wounded animals at the -;xperinental

exceptionally free from cattle lice during the past winter, as
judged from the results of visits to about 50 farms. Only a few
light infestations were found, even on farms that had heavier in-
festation .,during the previous year.
LO:TG-NOSED CATTLE LOUSE (Linognathus vituli L.)
Iowa. R. W. Wells (L.nrch 29): Cattle in the central part of the State
