The usual spring damage by cutworms is being reported from the
greater part of the country. The army-cutworm outbreak in western
and central Nebraska-continued well into late April. Towards the end
of May damage by the pale western cutworm was reported from parts of

Wireworms were reported as more or less troublesome from practi-
cally all parts of the country. In south-central and souLhern Illinois
several thousand acres of corn had to be replanted on account of the
depredations of these insects and in parts of South Dakota similar
serious damage is being reported.

The recently discovered wireworm Heteroderes laurentii Guer.was
reported as pupating in late April and early May, pupation continuing
throughout the month.

SAn epidemic of the flower thrips is reported from Michigan, princi-
pally damaging fruit.

The Hessian-fly situation has not changed materially since our
last report. Unfavorable weather gave this insect a decided setback
in western and central Illinois.

Mormon crickets are appearing in very threatening numbers in
Sanders County, l.con., a county in which severe outbreaks occurred
in 1926 and 1927.

The corn ear worm is now appearing quite commonly in southern
Mississippi and southern and central Texas.

Throughout the East-Central States damage by sod Wt'oro-.- to corn is
quite general. Similar damage is also reported from Kentucky, Missouri,
and Iowa.



A rather unusual outbreak of the southern corn leaf beetle
(1,Lvochrous denticollis Lec.) is reported from Indiana. In one field
90 per cent of the corn was eaten off below the ground cy t'r-se beetles.
Similar d-.:ia:e is bein- retorted from :-entuck.

The pear midge emerged in lar.-e numbers in the pear-grc-'-inrg portion
of the Hudson River Val?,ey, :Tew York State, znd will probably do serious
damage where control measures are not applid..

During the early part of .,ay practically all of the mature .arvae
of the oriental fruit moth pupated and a large perc-ntage of adults had
emerged by the middle of the month. Twig injury w-as observed in western
':ew York during the third week in the month, and to73rd the end of the
month similar injury was apePoaring in Connecticut. In ::aryland. the peak
of tm.-rgnce occurred about the lst of the month. In the G-eorfii fruit
belt the infestation arp.ars to be the lightest since the insect be-
came established in the Fort Valley district, and here it also a-peared
later than in previous years. In the 2ast-Central States Illinois re-
ported from 40 to 50 per cent of the peach twigs injured by ''ay 10, in
Pulaski County. The fruit moth has also been reported as appearing in
appreciable numbers in Ohio, Indiana, 1.ichigan, Xentuc!y, and3 the
northern and north-central parts of L*ississippi.

The first plum curculio observed to leave peach drops in the Fort
Valley district of Georgia was recorded on April 22, about two weoks
later than usual. There will, therefore, probably be v;ry little
... J;except to late varieties. In the East-Central Statr-s, par-
ticularly in the southern part, the plum curculio is seriously damaging
apples. The stone fruits were practically a failure in this region,
which may account for the unusual damage to apples.

The rusty plum aphid was reported as unusually abun'3nt in the
Fort Valley district of Georgia and in southern Mississi:i. "It was
also recorded from ::;braska and Utah,

An infestation of the grape phylloxera was discov-rd. in i6wo E3n
Gabriel vineyards in southern California. Svery effort is being made
to eradicate this insect.

Rather serious infestations of pecans by the pecan nut case bearer
were reported from Albany, Ga., and from Stone and Jackson Counties,
The situation with regard to/citroohilus mealybg in southern
California is more favorable than it has been any year since this insect
becam. a major pest in Los Angules County. Many properties recorded
as infested last year are now being reported clean ard. only a vz-ry low
percentage of the properties are being reported as heavily infested.

The California red scale is reported as being generally abun.iant
throwL$out the lo-ner Rio Grande Valley of r'xas and present indications
are that infestations vill be severe.

The vegetable weevil is being reported from several localities
in Mississip-oi, in some cases doing serious damage to tomato plants,
turnips, and carrots.

The seed corn maggot is reported as seriously d:m-.gin7 potato
sead pieces and corn in Ohio, Indiana, Michigan, and :iissouri, and
doing some d-mrnge in Iowa. It was also reported as destroying water-
melon seeds in Utah and peas in Minnesota.

The Colorado potato beetle appears to have been favored by the
prolonged drought along the north Atlantic Seaboard. Reports of unusual
abundance have been received from North Carolina to New York. On
May 21 adults of this insect were collected in St. Johns County, Fla.
This appears to be the first record of this insect as far south as the
Hastings area in this State.

The cabbage aphid is seriously abundant on seed kale in the
Norfolk district of Virginia where it may reduce the crop by half.

The weevil Tyloderma morbillosa Lec. is very serious in a number
of strawberry fields in western Washington. As high as 50 adults have
been found on a single plant and the plants so infested are killed in
about a week,

The first emergence of the Mexican bean beetle was observed at
Camden, Del., on May 6. In the Norfolk district of Virginia adults
were observed in the field on the first of the month.

The pea aphid has been worse on the Eastern Shore of Maryland
than it has been for in.ny years.

Heavy stripping of the early foliage of elm by C: li-r-bha
scalaris Lec. is being reported in Webster, Nuckolls, and Furnas
Counties in Nebraska.

In the vicinity of Augusta, Me., the larch case bearer has de-
foliated approximately one-fourth of the larch trees. ?'ny of these
trees have been killed by this insect in previous infestations.

A severe infestation of the spruce bui-crmn in the Shoshone National
Forest has been under way for three or four years.

The spruce needle mr.inr (Epinotia nanana Trcitsche) is reported
as seriously affecting spruces in northern Illinois and southern

Canna leaf rollers are very heavily infesting commercial plantings
of cannas in the southern part of Mississippi.

The Argentine ant has been found in three municipal greenhouses
in Baltimore, "2d.


The .-heat stem sawfly is reported to have passed the winter ith
100 per cent survival in the central part of Alberta. This pest in-
creased :Larkedly in 1929, and approximately 10 to 15 ti:-.E as many
larvae overwintered last year as in the year previous. Hea'." in-
festations are anticipated. this season if coditions r...- favorbl- ,

In southern Ontario observations indicate that the winter mor-
tality of larvae of the European corn borer was c.;-ciderably lower
than during the past threu yars. Given favorable conditions, an in-
crease in infestation may be expected during 1930.

Infestations of the early cutworm, tristicula Morr., r.have
been reported from sections of southern Alberta a.- south.w stsrn
Saskatchewan. Reports at present available do not indicate an, serious
or extensive damage.

The tarnished plant bug caused serious damage early in the season
to fruit buds in orchards of the Okanagan Valley, British Colw-bi?..
Pears were more seriously daaged than apples. This species has been
noted as conspicuously abundant in southern Quebec, near Montreal, and
in sections of southern Ontario.

A further decline in the abundance of budmoths, notably the eye-
spotted budmoth, is indicated in the Annapolis Valley, Nova Scotia.

L,-s of the European red mite wer,: more prevalent than usual in
practically all sections of the Annapolis Valley, Uova Scotia, and
were also considerably in evidence in orc'.ards in sections of Tmw7
Brunswick. !he cg-;s were hatching on May 9. In the Jr.Lapolis Valley
it is belivcid that this mite will probably be one of. th; worst orc-.ard
pests of 1930.

>. -of the European apple sucker commenced to hatch in the
i.nn,:..polis Valley, ';ova Scotia, on May 10. This species is reported
to be more numerous in the valley than for several years and is .-ide-
spread throughout the entire fruit district.

Tent caterpillars are again reported very numerous on
Island and in the lower Fraser Vall.., British Col-i'. -'.y 2'e
also noted as on the increase in sections of P-ince 7:-ard Island and
rei7 Brunswick.

The larch case bearer was exceptionally abundant on larch, in
Ontario, in the early part of "'ay, causing conspicuous foliage injury.

A severe infestation of ticks affectin-. cattle, occurred in the
interior of British Columbia, this sprin:, and rany cases of tick:


paralysis were reported from the Ticola Valley, Ashcroft, and th( it'arron
Valley, during April. In the Nicola district several hundred h-ad
wore sick and in various stages of paralysis, and a nrrbr died as a
result of the tick infestation. Blow flies also caused much trouble.
The recently d;ho.:ned cattl.,, when paralysed by thi ticks, fel1 on
the stony hillsides and brok; open the healing wounds, thus giving
access to the flies. The heads of many of thl.' cattle consequently
contained masses of i:' _ots right into the core of the horns.

and young larvae, as the infestation has been materially
reduced over that of last fall in the same fields. Ocoasional
fields, especially in'tbe southwest-central part of the State,
showed heavy infestation, but as a rule the spring brood does
not cause the normal amount of camsie.

M. K. Swenk (I..y 13): The first moths of the spring
brood emerged in the insectary at Lincoln on May 3, '-hich
is 16 days earlier than the first emergence in 1929 and
20 days earlier than th; first emcrg~nc. in 1928. The
first moths were collected in bait traps in the orchard
on :.':y 8, and others have been collected each warm night
since. The mortality of wintering larvae was very heavy
during the winter of 1929-30. Out of 611 larvae in
cocooning racks in the out-of-doors insectary, 316,or
nearly 52 per cent,died during the winter. About the
same percentage of w7int r-killed larvae are found under
natural conditions in thl orchard.

R. L. Parker (mIay 22): The codling moth is moderately
abundant at Belle Plaine; first eggs April 14; first
larvae M.ay 9, at legist three days old when observed, as

A. J. Ackerman ( 7 5): Emergonce of spring-brood moths
at Bentonville b,.g-n April 20. Approximately 1,300 moths,
or about 16.5 per cent of the overwintered larvae, emerged
between April 20 and ":!,y 4. In 1929 only about 6 per
cent had emerged by May 4. Because of the high mortality
of overwintering worms due to the January (1930) sub-zero
temperatures, a large supply of larvae was collected
in orchards during February, 1930, for supplementary
material. The emergnce of moths from these larvae,
kept i.. pupa sticks in the insectary, began the third
week in March, about one month earlier than the first
emergence of moths from fall-collected material.

Claude .ai-eland (May 22): The codling-moth activity
b..gan much c-rlier than in 1929. The first cover spray
was applied in 1930 earlier than the c.lyx spray "-as ap-

Calif. Spray-Chumical Co., Vol. 2, 1:o. 2, "Ortho News"
(L.ay 10): The first flight of codling moths took place
almost simultaneously in several northwest districts.
The first flight indicated by our b-it pots in the Broadway
district was on the night of April 22. This coincides,
practically, with moth flight recorded in the lower
"_-iZ.S Valley, at Selah and in the .enatchee districts.
Since this first flight fluctuating evening temperatures,
mostly cool, have caused intermittent emergence of
comparatively fe- moths. ,

trees. The highest catch for any one day was 11,571. The
highest nu.nbir collected from any one tree was 73, but
this tree was located in the corner of the orchard close to
a rock fill. The first emergence of the season was re-
corded on February 25 when five adults were collected.
The next earliest emergence was hiarch 17.

0. I. Snapp (April 28): The first curculio larvae of the
season left peach drops today. This is about two weeks later
than usual. Under normal whether conditions 90 per cent of
the larvae in drops leave during April. As the insect is
getting a late start this year, I am anticipating only a
very light second generation before the close of peach season.

CITROPHILUS .MEALYBUG (Pseudococcus gahani Green)

Monthly :Tens Letter of Los Angeles Co. Agri.CoT-m.,
Vol. 12, No. 4 (April 15): Reports of special inspectors
engaged in the annual citrophilus meal,'bur- orchard survey
bear out early statements to the effect that the situation
r._-grding the mealybug is the most satisfactory, from the
standpoint of control, that it has been since this insect
became a major pest of citrus in Los Ang.-les County. Although
only 45 per cent of the 18,000 acres to be inspected have
been so far covered, the results seem indicative of the
general trend of conditions. On 18 per cent of the 8,130
acres so far inspected, representing 1,448 acres of citrus
recorded as infested last year, no mealybug has been found
this season. Seventy-seven per cent or 6,280 acres have graded
trace to light, while only 4.3 per cent or 350 acres have
graded medium, and 0.7 per cent or 52 acres have graded heavy.

He found numerous small creatures crawling on the sa.mples
examined. It developed that, as this material is cut in
large sheets and stacked in piles, perhaps 5 feet high,
before it is entirely dry, it made conditions suitable
for mites to breed. On arrival here the s-.7Is were dry
and all specimens were dead.

A l-ITE (Hr ,0mogam-sus sp.)

11iew York

,. Moore (May 12): A pest which is causing us trouble
is a mite which Dr. Ewing determined as a species of
Haemogamasus, This mite originally came to us in a bag of
rabbit fur infested with clothes moths. "ae again observed
it in a rug, infested with clothes moths, obtained in
Yonkers, the same rug previously mentioned containing
parasitized clothes moths. I have no positive proof as yet,
but feel very confident that this mite is attacking thu eggs
and larvae of the webbing clothes moth! This is rather in-
teresting, as the species of this genus are considered
parasites of moles and field mice.
