THE MORE IMPORTANT RECORDS FOR MARCH, 1934

During the month reports of grasshoppers emerging were received
from several places in the Northwest. These refer to the noneconomic
species which passed the winter as nymphs. The economic species, so
far as our records show, have not yet started to emerge in the North-
west, although they were reported as emerging in large numbers late
in the month in the Salt River Valley of Arizona. The winter through-
out the Northwest has been especially mild and dry and there is .every
indication that the grasshoppers have overwintered in large numbers.
Severe winds in South Dakota have so badly blown the soil in some
areas that eggs are exposed or buried so deep that there is but little
chance of their hatching. However, despite these conditions there
appear to be plenty of eggs to cause a very serious infestation.

Mormon cricket outbreaks are expected on the Fort Hall Indian
Reservation and near Idaho Falls in Idaho, and on the Crow Indian
Reservation in Montana. A second infestation in Montana occurs west
of the Crow Reservation and extends into the State of Wyoming.

Over much of the territory infested by the Japanese beetle heavy
snows in the period of extremely low temperatures during the past
winter kept the soil temperature well above the lethal point for this
insect and no unusual winter mortality is expected.

Up to the middle of January the chinch bug had suffered only 5
percent mortality in Indiana. By the end of March 3 percent winter
mortality was recorded from Missouri, with similar low mortality re-
ported from Kansas, Nebraska, and Iowa. The severe weather that pre-
vailed during the last few days of the month, however, may have a
decided effect upon the chinch bug populations in parts of the infested
area.

Reports from Indiana and Tennessee indicate that the hessian fly
has passed the winter very successfully in that section, having
suffered but 4 percent winter mortality, while reports from Kansas
indicate that approximately 7 percent died during the winter months.

Examinations made in New Jersey indicate that the corn ear worm was
unable to withstand the severe winter temperatures. In Missouri, however,
some pupae have beun found that passed the winter successfully.

The March cold spell in Missouri, when temperatures reached 14 below
zero, resulted in the death of about 30 percent of the codling moth larvae
that were above the snow line. Heavy mortality was reported from the New
England and Middle Atlantic States. From Kansas to the Pacific Northwest
winter mortality has been negligible. In Kansas a few pupae were found
durin.r the first part of February and in the Pacific Northwest pupation was
well under way during the second and third weeks of March. Reports from
Washin-ton and California indicate that along the Pacific Coast codling moth
development is some 10 days to 3 wee's earlier than usual. On March 13 a
moth was collected in the field in Sacramento County, California, and by
the 24th the adults were out in considerable numbers.

The San Jose vcale appears to have suffered severe winter mortality in
the New England and the Middle Atlantic States. Similar severe winter
mortality is reported from Missouri. Observations made in Massachusetts
indicate that -300 F. resulted in killing 89 percent, -22 F. in killing 75
percent, and -18o F. in killing 70 percent of the scales above the snow line.

The first plium curculio collected this season at Fort Valley, Ga., was
found on March 21, indicating the probability of two broods in this section.

Grape leafhopper populations are very heavy in the San Joaquin and
Imperial Valleys of California, and present indications are that infestations
will be severe.

A small infestation of the vegetable weevil was found in Sacramento
County, Calif., this spring. This is said to be the first positive record
for this insect in the Sacramento Valley.

The Mexican bean beetle suffered heavy mortality in open fields in New
Jersey. This does not, however, preclude the possibility that this insect
successfully wintered over in the wooded areas. Adults that had success-
fully passed the winter were collected late in March in West Virginia.

The harlequin bug suffered complete mortality in open fields in New
Jersey. No reports on this insect from other northern States have been
received.
The cotton leaf worm produced successive generations throughout the
winter in Haiti, the last two pupal periods comin< the latter part of January
and the latter part of February. Observations that will be made in Florida on
the first appearance of the moths this year may possibly be associated with
the observations being made in Port-au-Prince.
Possibly owir.- to the very mild winter in the West, the fall and spring
canker worms produced adults during the early part of January. The infesta-
tion in KE,.nsas is the heaviest in man'y ye:irs.
The European pine shoot moth suffered henvy winter mortality, as high
as 99 percent mortality having been recorded fror points in Mnssac 'usetts
and 80 to 90 percent in Connecticut.

GENERAL FEEDERS

GRASSHOPPERS (Acrididae)

North Dakota. J. A. Munro (March 19): Numerous specimens of noneconomic forms
of grasshoppers have been received from farmers in western counties during
the past winter. Conditions to date appear to have been ideal for the
overwintering eggs of the economic species.

South Dakota. H. C. Severin (March): In South Dakota we have had much wind
and blowing of soil. In some areas the soil has blown to such an extent
as to expose many grasshopper eggs, which have dried out and died. Along
fences the soil has sometimes accumulated and buried the eggs from a few
inches to 2 feet or more. However, there are plenty of eggs that are pass-
ing the winter successfully. The winter has been exceptionally mild and
dry.

Iowa. H. E. Jaques (March 24): Some nymphs are showing up. (These are
probably noneconomic species. J. A. H.)

Nebraska. M. H. Swenk (March 19): Grasshoppers are moderately to very abundant
in northeastern, northern, and western Nebraska. From Chase County comes
the report that in the Frenchman Valley grasshoppers have lived over the
winter, and that during the second week in March they were eating around
the edges of the wheat for a depth up to 25 feet. This probably refers to
Chortophaga viridifasciata DeG., the green-striped grasshopper, or to
species of Arphia or Pardalophora.

Arizona. C. D. Lebert (March 9): Young grasshoppers were reported as being
very numerous on 80 acres of alfalfa east of Gilbert, a short crop of
alfalfa having been badly riddled. (March 21): Melanoplus mexicanus Sauss.
are hatching by the thousands on ditch banks and fence rows in the Mesa-
Chandler area. They are confined almost entirely to Bermuda grass along
fence rows and ditch banks at present. Control measures are being practiced
in this area.

Wyoming. 0. L, Corkins (March 20): Grasshoppers have wintered normally and
are very abundant.

Utah. G. F. Knowlton (March 21): No grasshoppers have been observed as yet.

MORM1ON CRICKET (Anabrus simplex Hald.)

United States. Division of Cereal and Forage Insects (March 2): In Idaho, aa
outbreak of this pest has been in progress on the Fort Hall Indian
Reservation at Blackfoot for the past two years. The Bureau of Entomology,
the Idaho State authorities, and the Indian Service have succeeded thus far
in keeping this outbreak under control but it again threatens to be a
serious problem in the spring of 1934. Another outbreak is forming near
Idaho Falls and St. Anthony, Idaho. In Montana a serious condition due
to this insect pest has appeared on the Crow Indian Reservation near the
Pryor Mountains where the insects are beginning to invade privately owned
lands. A survey made by State authorities in the summer of 1933 showed
that 120,000 acres of land on the Crow Reservation was infested with the






58 -

Mormon cricket and that about 15 square miles was infested in the Dryhead
area west of the reservation near the Wyoming boundary. The insect is
reported to be present in large numbers in the latter State in territory
contiguous with the infestation in Montana previously mentioned.

S ARIY CUIWOPR,: (Chorizagrotis auxiliaris Grote)

Kansas. H. R. Bryson (March 20): The army cutworm is moderately abundant in
wheat and alfalfa fields. At Manhattan the larvae are more plentiful in
the old alfalfa fields than in new fields. Some damage to wheat has been
reported from Winfield, Cowley County, and in the vicinity of Hutchinson,
Reno County.

Wyomin;. C. L. Corkins (March 20): C. .a2ixiliaris is moderately abundant but
not active in Hot Springs County.

ALFALFA W-EWORM (Loxostege commixtalis Walk.)

Kansas. H. R. Bryson (March 20): Many overwintering larvae in tubes were
sent in from Hoxe, Overwintering tubes were said to be very numerous
in fields where piFweeds were present. There have been heavy flights of
moths during the last few years.

WIRAZ7ORI.S (Elateridae)

New Jersey. R. C. Burdette (March): A few wireworms are appearing in plant
beds in northern New Jersey.

Indiana. J. J. Davis (M14arch 27): Wireworms are reported as abundant in some
muck fields of northern Indiana.

Texas. F. L. Thomas (March 20): Wireworms are very abundant at Nixon, Gonzales
County. A correspondent states that he has planted corn the third time and
that wireworms have destroyed practically all plantings.

California. E. 0. Essig (March 22): Wireworms are moderately abundant in the
Delta Region.
A. E. Michelbacher (March 21): Limr-onius canus Lec. was moderately abundant
at Courtland, Sacramento County.
M. L. Jones (March 16): Tulare County reports wireworms as causing slight
damage to 50 acres of truck crops and melons z.nc-rally during February.
F. H. 77ymore (March 21): Wireworms are moderately abundant at Davis, Yolo
County, attacking tomato plants in cold-frame beds.

JAPA2TZSE BEEZLE (Popillia .n-.nica ".

New Jersey. J-,nc.nese B-.tle Laboratory (Dur. 1::t.) (March 2): Although the air
temperature for the month in New Jersey reached as low as -13o F., the soil
te-peratures recorded at the Moorestovwn laboratory did not go below 220 F.
Th- larvae of the Japanese 'eetle does not withstand temperatures much
below 15 F. This cold wave has been accompanied by snow, which has so
protected the .-rouind that the te"', cratiure-s apparently have not reached a
point where they would kill many larvae.

KOO-TSABE (Ephydra hians Say)

Nevada. G. G. Schweis (February 23): Winnemucca Lake is a body of water
approximately 25 miles long and from 6 to 10 miles wide. It formerly
was a fresh water lake but of late years the streams that fed it have
been diverted for irrigation purposes Lnd the lake is now very saline.
Fish formerly abounded there in great numbers but the lake is now devoid
of all fish life so far as I know. Great quantities of seaweed abound in
this lake and this weed is apparently the breeding place for the insects
we are sending you. These flies are so numerous that during the warm
part of the day, as they fly along the shore, you would think a snowstorm
was in progress if the flies were not black. As soon as the sun dips
behind the horizon the insects all fly in a certain direction and by night-
fall they are clustered in great heaps in depressions or under bushes,
where they apparently seek some protection from the chill night air. The
larval form apparently is of some value as duck food, as ducks that I
have killed there have had their gullets practically filled with small
maggots. Ducks occur there in great numbers. (Det. J. M. Aldrich.)

COMi.'DIT RED SPIDER (Tetranychus telarius L.)

Virginia. H. G. Walker (March 26): Examination of strawberry fields in
Princess Anne County have shown that some of the fields are infested.

North Carolina. W. A. Thomas, Monthly Letter, Bur. Ent. NTo. 237 (February):
"On January 30 the temperature at Chadbourn dropped from normal spring
weather levels to 8 F. with a maximum temperature during the day of 260 F.,
followed by another drop on the morning of January 31 to 5-o F., which
apparently is a low record for the section. Following this low temperature,
strawberry leaves infested by the red spider were collected and brought to
the laboratory for examination. These examinations revealed that practically
all adults and nymphs had been killed, but the eggs were apparently not
affected. These were hatching freely within 3 days. The red spider has
been particularly abundant on strawberries during the past year (1933).
This condition has been greatly aggravated by the long-continued drought
which lowered the vitality of the plants."

Mississippi. C. Lyle and assistants.(M4arch): Red spiders were found to be
moderately abundant on azalea leaves at Pecan, Jackson County, on March 5.
They are generally distributed in strawberry fields in Lauderdale and
Jackson Counties.

Texas. F. L. Thomas (March 15): The red spider is abundant on strawberry
plants in Galveston County, according to J. N. Roney. About 50 percent of
the plantings are infested and control mr.as:ua-es are being practiced.

California. M. L. Jones (March 16): Santa Clara County reported the red
spider as causing slight damage on violets and sweet peas during January
and February.

CEREAL AND FORAGE-CROP I ISEC T S

'77H.AT AMD OTHER SMALL GRAITNS

CHII73H BUG (Blissus leucorter, Say}-)

Indiana. P. Luginbill and W. B. Noble, Monthly Letter Bur. Ent., No. 237
(February): Hibernating chinch bugs evidently suffered very little
mortality in the vicinity of Lafayette up to January 19. Of 465 bugs in
bunches of corn husks taken from the field on that date, only 5 percent
were dead. Up to that time the weather was very mild, the lowest temperature
recorded at Lafayette 'raving been -29 F., with very little snow and
precipitation considerably below normal.

Illinois. W. p. Flint (.MIaich 20): Chinch bugs show only about a 3 percent
winter mortality in recent counts at Urbana. It is estimated that there
are at least five times as many b- s in hibernation as there were a year
.ago on the same date.

Iowa. C. J. Drake (March 26): Winter mortality has been extremely low; in
counts we found that considerably less than 1 percent of the b->s perished
during the winter months.

Missouri. L. Haseman (March 21): The chinch bug situation continues serious.
Late February burning in some, cases ave? 50 percent kill but since burning
severe weather has killed over 15 percent in burned as well as unburned
clumps.

Nebraska. li. H. Swenk (March 19): The chinch bug is very abundant in south-
eastern !T-bracka.

Kansas. H. R. Bryson (March 20): Chinch bugs were more numerous in hibernation
this winter at Mlanhattan than they have been for five or six years. This
is generally true for central and southeastern Kansas. Ov.in,- to the mild,
dry winter very little mortality resulted this year. Adults were taken on
Kentucky bluegrass plots, March 15.

.2SSIAU FLY (Phytopha.a destructor Say)

Indiana and Tennessee. :':nthly Letter Bur. Ent., No. 237 (February): Practi-
cally all the hessian fly were in puparia and dormant at Lafayette, Ind.,
in January. At Fayetteville, Tenn., however, the mild weather and ample
rainfall during January actually caused a little pupation. Curtis Benton
found 2 live pupae in 100 puparia dissected on January 26. His dissections
of puparia late in January showed about 4 percent mortality.

Nebraska. M. H. Swenk (March 19): Hessian flies are moderately abundant in
south-central and southeastern Nebrasla.

Kansas. H. R. Bryson (March 23): Hessian flies are scarce at Marnhaittan and
normal in abundance in the central part of the State. A report from Havana,
Mont.-om03ry County, indicates that the fly is moderately abundant in the
southeastern part of the State.
J. R. Horton, Monthly Letter Bur. Ent., No. 237 (February): Dissections







- 41 -


of over 300 puparia of the fall generation during December and January
indicate that approximately 93 percent of the larvae are viable and that
over 55 percent have reversed their position in the puparia.

A CRAITE FLY (Tipulidae)

California. A. E. :lichelbacher (March 21): On the 28th of February serious
injury to a grain planting by tipulid larvae was observed near Niles. The
stand was destroyed over a rather extensive area.

TOBACCO THRIPS (Frankliniella fusca Hinds)

Florida. J. R. Watson (March 20): Moderately abundant on rye during the latter
part of February and March.

CORN

CORN EAR WORM (Heliothis obsoleta Fab.)

New Jersey. T. J. Headlee, R. C. Burdette, and B. F. Driggers (March): Diggings
made for pupae in southern New Jersey showed all of them to be killed by
the cold weather.

Florida. J. R. Watson (March 20): The corn ear worm is scarce.

Missouri. L. Haseman (March 21): Recent diggings show that some pupae have
survived the winter.

Texas. F. L. Thomas (March 20): The first eggs were found by Dr. R. K. Fletcher
in alfalfa in Burleson County today.

ALFALFA

ALFALFA WEEVIL (Hypera postica Gyll.)

California. E. 0. Essig (March 22): Alfalfa weevils are moderately abundant
throughout infested areas.
A. E. Michelbacher (March 21): The alfalfa weevil situation is as follows:
In the Tracy area the weevil can be found in all fields. On March 20 the
highest population was encountered at Vernalis. There an average of 1,198
larvae were collected to the 100 sweeps. In the field examined some damage
was noticeable, although not of a serious nature. In all other fields
examined the average number of larvae taken per 100 sweeps ranged from
2 to 200, in which fields no damage is apparent. In the Pleasanton district
average larval counts of from 67 to 516 were taken on March 15. Up to
that time no injury was apparent, and every indication was that the alfalfa
for the most part would reach maturity before much injury occurred. It is
the young vigorously growing fields in which the larval counts remain very
low. In the country about Niles the highest larval counts have been taken.
In one field an average count of 2,020 was taken to the 100 sweeps on March
14, and in other'fields on the same date average counts of as high as 575
were taken. One field was swept today and an average count of 754 larvae
was collected. The average taken from this field on the 14th was 552. In
this district some injury is noticeable, but this is not true of all fields.








- 42 -


PEA APHID (Illinoia pisi Kalt.)

Kansas. H. R. Bryson (March 20): Pea aphids are more plentiful than usual.
They are more abundant on fall-sown alfalfa than on the old stands. Winged
forms were found in the fields as early as February 15. They are reproducing
rapidly at present and if the cold, dry weather continues, an outbreak is
likely to occur. Unlike other years, the infestations do not occur in
spots, but they are generally distributed over the entire field.

California. A. E. Michelbacher (March 21): The pea aphis on alfalfa is not so
serious this year as it was last.

SUGARCANE

SUGARCANE BORER (Diatraea saccharalis Fab.)

Louisiana. W. E. Hinds (March 26): Winter mortality of the sugarcane borer
appears to be usn.sually low. Possibly this is due to the fact that the
winter has been t.nusually cool through February and March, with less
fluctuation betie en maximin and minimuL. Minimum temperatures have 'not
gone below 25 i in the real cane belt. Pupation of hibernating larvae
often occurs during February, but this year the first pupae were found
during the last week of March at LaPlace.


FRUIT INSECTS

APPLE

COL.iG :.MOTH (Carpocapsa pomonella L.)

Vvrmont. H. L. Bailey (March 28): The codling moth is moderately a'buindant;
some larvae have been reported dead from winter killing .

Massachusetts. A. I. Bourne (March 28): Fr.jm such observations as it has been
possible to make at Amherst we anticipate a considerable mortality of the
codling moth.

New York. P. J. Parrott (March): Many hibernating larvae have been killed by
low temperatures in sor-ie sections of western New York.

New Jercv.-,. T. J. Headllee, -%. C. Burdette, and B. F. Dri,--ers' (March): The
coiling moth is moderately abundant.

Delaware. L. A. Stearns (March 23): T, ,:s been a 40-50 percent mortality of
overwinterin- larvae. No pupation yet.

Georgia. C. H. Alden (March 19): There as been no pupation no-,id at Cornelia.

Missouri. L. Baseman (March 21): At Columbia the recent -14 F. temperature
has apwarently killed about 30 percent of larvae exposed above the snow line.

K arsc,. H. R. Bi-:.son ("i'rch 20): Ti-h codling moth wintered over in -reater
numb, rs than it has been known to do previously in northrcatern Kansas. The








- 43 -


mortality during the winter has been negligible. Overwintering larvae are
abundant over the State. Some pupae were taken at Manhattan the first part
of February.

Idaho. R. W. Haegele (March 20): Codling moths are very abundant in southwestern
Idaho. Larvae were pupating in abuindance during the week of March 12 19.

Washington. E. J. Newcomer (March 14): The season is the earliest recorded in
the last 20 years for the codling moth, being a week or 10 days earlier
than the very early season of 1926. The winter has been extremely mild,
the lowest temperature recorded having been 21 F. on November 29. This,
together with a very large worm population in neglected orchards, is going
to make control very difficult this year. The calyx spray will probably
start about April 10, a month earlier than in 1933.

California. S. Lockwood (March 24): On March 13 an adult was found in a pear
orchard in Sacrenento County. This is the earliest date that adults have
been caught tha. I know of. Reports from other areas indicate that the
moth is out in _-nr.siderable numbers. This is about two to three weeks
earlier than usu;il.

EASTERN iTET CATIERPILLAR (Malacosoma americana Fab.)

Vermont. H. L. Bailey (March 28): The eastern tent caterpillar is moderately
abundant. Winter killing is apparent in egg masses collected at Montpelier.

Massachusetts. A. I. Bourne (March 28): At Amherst eggs from orchards where
temperatures ranged from -20 to -30 F. are hatching apparently normally,.

Connecticut. W. E. Britton (March 23): Egg clusters on twigs are moderately
abundant.

West Virginia. L. M. Peairs (March 24): EgF masses are numerous at Morgantown.

Arkansas. W. J. Baerg. (.March 21): Young caterpillars began emerging from
ege-shells on March 20 at Fayetteville. On the 21st about 80 percent had
emerged. Egg masses are very abundant this year.

FRUIT TR-E' LEAF ROLLER (Cacoecia argyrospila Walk.)

California. E. 0. Essig (M-.rch 22): Fruit tree leaf rollers are moderately
abundant; they are just appearing in middle California.
M. L. Jones (March 21): rmit tree leaf rollers are moderately abundant
working in the base of young apricot fruits at Vacaville, Solano County.
F. H. W7ymore (March 21): Fruit tree leaf rollers are moderately abundant
in Solano and Sonoma Counties. Although common in many orchards, little
damage has resulted from their feeding.

APHIDS (Aphiidae)

Vermont. H. L. Bailey (March 28): Fruit aphids, (Aphis pomi DeG.) are scarce.

Massachusetts.'A. I. Bourne (.,arch 28): No actual counts have been made on
plant lice at Amherst but we have found a slight amount of hatching and







- 44-


a very large percentage of shriveled eggs. This is also confirmed by
reports which we have received from Connecticut.

Connecticut. W. E. Britton (March 23): Fruit aphid e--;s are scarce on twigs.

New York. P. J. Parrott (March): Grain aphid (.Rhopalosi-phum prunifoliae Fitch)
and green aphid (A. poti) eggs survived the winter fairly well and are
moderately abundant.

New Jersey. T. J. Headlee, R. C. Burdette, and D. F. Driggers (March): Apple
aphids (A. pomi) are moderately abundant.

Delaware. L. A. Stearns (March 23): Fruit aphid eggs are moderately abundant
over the State.

West Virginia. L. M. Peairs (March 24): Fruit aphid eggs are moderately
abundant at Morgantown.

Georgia. C. H. Alden (March 19): Fruit aphid eggs are moderately abundant on
trees at Cornelia.

Missouri. L. Haseman (March 21): Aphid e-.:s are less abundant than usual.

Mississippi. J. P. Kislanko (March 20): A. pomi is scarce at Hattiesburg.
Stem mothers were observed on quince.

Oregon. D. C. Mote (March 24): Fruit aphids are out in great numbers more
numerous than normally in the Willamette Valley.

California. E. 0. Essig (March 22): The green apple aphid, A. pomi, was
present in apterous form all winter on Cotoneaster in the San Francisco
Bay region. It is now abundant in manny places.

APPLE LEAFHCFPZRS (Cicadellidae)

New York. P. J. Parrott (March): Apple leafhopper. eggs on wood brought into
the greenhouse are hatchin-.

Kansas. H. R. Bryson (March 20): A red and white leafhopper, Erythroneura sp.,
hibernated in large numbers in apple orchards at Troy.

SAN JOSE SCALE (Aspidiotus perniciosus Cornst.)

Vermont. H. L. Bailey (March 28): There were very few living insects on bark
received from a survey in the vicinity of Brattleboro, Windham County. The
scale is found in only two or three localities in Vermont including the
one mentioned.

Massachusetts. A. I. Bourne (March 28): Professor Whitcomb of Waltham made
extensive counts on San Jose scale from orcharls which had been subjected
to varyir.- degrees of temperature, with the following results: Orchards
with -:iiinm recorded te-.perature of-30 F., 89.3 percent of the scale was
dead; -22 F., 75 percent dcad; and -18 F., 70.1 percent idLad.








- 45 -


Co:o:;.ctic't. W. E. Britton (March 23): The San Jose scale is scarce; there
has been heavy winter mortality.

New York. P. J. Parrott (March): From 90 to 99 percent were killed by winter.
R. E. Horsey (March 25): The San Jose scale has not been very common at
Rochester and has been easily controlled. It is not considered a serious
pest with us.

South Carolina. W. C. Nettles (March 19): The San Jose scale is moderately
abundant and giving trouble in Oconee County.

Georgia. 0. I. S: ;." (March 17): Low temperatures during the winter have
not killed many San Jose scales at Fort Valley. The average percentage of
live scales on certain peach trees on February 17 was 82.2 and the average
percentage alive on these trees on March 17 was 70.5.

Florida. J. R. Watson (March 20): The San Jose scale is moderately abundant.

Illinois. 7. P. Flint (March 20): A survey during the fall of 1933 indicated
that in peach ond apple orchards moderate to severe infestations had
increased from 6 percent in 1932 to 27 percent for 1933. Spring counts
March 19 show 15 to 50 percent of the scale alive.

Iowa. H. 2. Jaques archrh 24): The San Jose scale is moderately abundant.
in southeastern Iowa.

Missouri. L'. Haseman (March 21): Recent counts on pear at Columbia show only
1.5 percent survival of the San Jose scale, with apparently considerable
parasitization.

Mississippi. C. Lyle (March 22): The San Jose scale has been reported from
moderately to very abundant generally. Slight infestations were observed
on spirea and honeysuckle at Greenwood in Leflore County and West in Holmes
County during the pest few weeks. Complaints of the occurrence of this
species on these two plants are rarely received.

Texas. F. L. Th(rna (Mearch 20): The San Jose scale was very abundant at
Ft. Davis, Jeff Davis County, on March 10, on a few apple trees that had
not been properly sprayed.

California. IA. L. Jones (1,'arch 16): Merced County reports the San Jose scale
as causing medi-m; d.mago to deciduous trees generally, and Tulare County
reports the scalc as moderately ab-ndant on 5,000 acres of deciduous and
citrus trees in February.

PINE

ZLTR:iPZ1- PINE S?'OOT MOTH (Rhyaconia" bgoliana Schi'f.)

Massachusetts. P. A. Berry, Monthly Letter Bur. Ent., No. 237 (February):
One hundred larvae were removed from infested shoots of pine collected
in each locality of ,'akefield and Brookline, and were examined to
ascertain if they were living or dead. In each collection only 1 of the
100 larvae examined was alive. It is presumed that the death of the
larvae was due to the unusually low temperatures of the latter part of
December. W., of t'., larvae from Wakefield and 7 from Brookline con-
tained the immature stage of a parasite of the -;,rnu Orgilus,all dead.
Adults of 0. o.b... _rat,-1 (Nees), a parasite received from Er'..p.., had been
liberated in each of the infestations from which the European pine shoot
moth larvae were obtained and it was probably, this species that was
found in the parasitized larvae.

in the shoots have been killed during the winter. Red, Scotch and mugho
pines in south-central Connecticut are attacked.

MOUNTAIN PI1M BEETLE (Dendroctonus monticolae Hopk.)

Idaho. J. C. Evenden, Monthly Letter Bur. Ent., No. 237 (February): In
1927 a small outbreak was reported from the eastern portion of the
Nezperce irT-tional Forest. This outbreak was apparently a chance infes-
tation from the severe epidemic that existed in the lodgepole pine stands
of the Bitterroot and Salmon Forests. Since that date the infestation
has spread northward, devastating all lod'coole pine stands in its path.
An analysis of the 1933 r:..,-:r reports shows that this epidemic has
passed through the ic-.zperce and Selwray Forests, and now rests in the
Clearwater, with a few spots of infestation on the St. Joe Forest.
Although it is accepted that the remaining lodgepole pine stands within
these forests are doomed, the seriousness of the situation rests upon
the possibility that the insect may transfer its attack to white pine
after depleting the lod7epole pine stands, As these tree species are
equally acceptable hosts of the insect, and as white pine in association
with lodgepole is already being attach-.d on the Clearvater, there is but
small hope that such an occurrence will not take place. There are large
bodies of valuable western white pine on the Clearwater and St. Joe
National Forests which at this time are seriously threatened.

POULTRY

BEDBUGS (Cimei lc.t;U-tu]i3. L.;)

Ohio. N. F. Howard (March 28): A severe infestation of bedbugs in chicken
coops at South Point was recently brought to our attention. The insects
became so numerou-s that it was necessary to remove the chickens and com-
pletely sterilize the house. In one instance the bugs were so numerous
that the farmer had to dispose of all his chickens but a few which he
isolated and treated by hand. The identity of the species has not been
verified by a specialist. I understand that there was a heavy infesta-
tion in the small-animal horse where experimental rats and other small
animals are kept at Ohio State University.


HOUSEHOLD AND STORED-PRODUCTS INSECTS

TERMIT1-S (Reticulitermes spp.)

Connecticut. M. P. Za-ppe (March 23): Termites are becoming more destructive
to buildings. R. flavipes Koll. was reported attacking buildings at ITew
Haven and Westport. Several years ago this was rather rare but during
the last 3 years we have -umy reports of injury by this pest to homes
potso injury by this pest to homes
and public buildings. On Prospect Street, New Haven, many new expensive
homes are infested. Several years ago this land was covered with wood
but has recently been developed into building sites.

West Virginia. L. M. Peairs (March 24): Termites reported at Morgantown,
Fairmont, and Parkersburg. No less than 11 reports of adult emergence
during week of March 10 17.

Mississippi. C. Lyle (March 22): Requests for information about controlling
termites have been received during the past few weeks from alsmot all
sections of the State.
Kansas. H. R. Bryson (March 20): Owing to the mild winter, termite activity
continued throughout the winter months. Many new local infestations
have been found. Apparently four species of subterranean termites are
present in Kansas.

Utah. G. F. Knowlton (February 28): Termites (R. tumice-ps Bks.) are
seriously damaging electric light poles in various parts of the Cache
Valley, untreated lod-'-e)ole and other native -oine p-ooles being damaged
most severely. Co-ra--y representatives report that untreated -ooles are
s'ietimes severely mined and destroyed within three years. (Det. T. E.
Snyder)

California. F. H. Wymore (March 21): The western or subterranean termite,
R. h sre Bks. has been actively preparing the emergence tubes in
buildings and greenhouses during the past two weeks for the spring
flight; however, no swarming has been observed or reported as yet.

Mississippi. C. Lyle (March 22): Shelled butterbeans showing severe injury
were received from Durant, Holmes County, on March 8.

PEA =7.IL (Bruchus pi sorum L.)

Idaho. T. A. Bri-.rdley, Monthly Letter Bur. Ent., No. 237 (February):
Prospects are favorable for a decided increase in pea weevil damage this
season. If the weather continues mild the only redeeming feature of the
situation will be the small hibernating population. An interesting
result of the continued mild weather is thlE survival of volunteer peas
in the winter wheat. Last fall durir.- the harvest season unusual quan-
tities of peas were shattered because of climatic conditions. Whole
fields seeded to winter wh"e.t resembled pea fields, so great was the
quantity shattered. Favorable climatic conditions allowed practically
all of these peas to germinate and, thus far, these peas have survived.
It is possible, should the warm weather continue, that these peas will
survive and absorb some of the weevil damage. This would alleviate the
situation this crop season, but would breed larzc r.ca weevil populations
for 1937.

A SPI:-R BEETLE (Ptinus tectus Boieldieu)

Was'..iy-ton. M. H. Hatch (February 23): Tlis beetle is numerous in a grain

A NOTE FROM HAITI By G. N. Wolcott

CCIT,2 LEAS 7CR.1 (Al-b.L--a c-r.nacea Hbn.)

March 8, 1?,: I have just received word from Mr. Andre Au-iant of Port-au-

Rico for over a year, the last small outbreak havir.ng been eliminated in
January 1933 on a small field of an experimental planting at Rio Piedras.
It occurs to me that the presence of A. rgillrncea in n-itl throughout
th: winter -,i indicate the possibility of an early occ,:rrence in Florida
