The chinch bug bc-,anr scattering in hibernating quarters during
the third we' of the month, and by, the last of tIhe month flights were
reported from Indiana, Illinois, Kansas, and Oklahoma.

During the last of March and the first week of Aopril outbreaks
of thegreen bug were r ,rted fror Ceorgia.

The hessian fly is reported es occurrinjg in latrg-e numbers in
northeastern Oklahoma on wheat sown ecrly for greazin. A heavy in-

In other infesled fields in the San Joac in Valle~" the counts have

Arizona. T. P. Cqssidy (Anri 1 2.7): -enorts were received during the ,nast
week from Sacrton and the Salt -iver Valle" that plint lice were
causing' serious d:.,--e to alfalfa. Inspections rmnre in several alfalfa
fields in the Salt River Valley showed the izfest, tion to be very
heavy as literally thousands of plant lice could be collected in a net
by sweeping the plants a few times.

Nevada. R. A. Blancuard (March): Periodic observations in western Nevada
indicate the possibility of an outbreak of the nea aP.hid. T-c relative-
ly mild c-r.J earlv spring weather has allowedd vivi-rarous forms to sur-
vive in small numbers. During normal years winter temnerntures are
low enoug- to destroy green growth, preventing the anhids from passing
the winter in any but the egg stage. The fields in tne vicinity, of
Reno had green growth fromT 1/2 inch to 2 inches tall on March 23, and
examination in six fields showed nonulation7 ran:ing" from 4 to awon"x-
imately 300 anhids ner five-clump sample.

Oregon. L. P. Pockwood (April 10); This species averae'ed 59 anhids ner
100 sweeps in a field of alfalfa on high ground, showing good s-orinH
growth at c"' ra. Many were quite small and there were no alates.
(Anril 13): In the Willamette Valley early fall-sown vetch, seeded in
August or Se-otember, as cover crops, showed ",,oderate infestations, as
many as 350 aphids per 100 swee'os in son-e c"ses. Vetch fields, for
hv or seed, seeded in Octotbe showed ver- fev, or o0 aphids. Two
alates were sent from Auust-sown vetch, but none from October vetch.
Coccinellid beetles, Dorticularlv Hinoonamia cowvergens 3-er. are be-
coming aoI',.'.?nt in vetch'fields. H. quinqegs. grt.? oblioua Csy. and
H. sinuata smuria Lec. begpn leaving their hibernation cache on Anril

California. R. A. Blanchard ("',rch): An outbreak on alfalfa anne-iers
orobrble in the Antclone Vnllee of southern California. The severity
of this will defend e.'oon weather conditions during the early )'-rt of
Aoril. The nonultj. ns are building u) later than usual. There seems
to be some correleion between this condition and tie fact th't ver"
few severe frosts occurred during the early sErnins, to rune back the
alfalfa growth. The average temperature, howveve lis been sufficiently
low to allow only slow growth of the plants. Sch slow steady growthh
has been observed nreviouslyr to result in slow c-r .:.tion of ids,

cold in the winter of 1933-34 caused a tremendous mortality of the
European pine shoot moth in southern New England and New York, almost
exterminating the pest in some plantinzs- in eastern Massachusetts. How-
ever, it has been found that on low-growing pines, especially Pinus mon-
tana mughus, enough R. buoliana survived to build up considerable in-
festations in several localities. Collections taken this spring. from
mugho pine heve shown a mortality from all causes other than wrasitiza-
tion of 21 percent at Lynn, Mass., and of 22 percent at lelmont, Mass.,

Reports from Jacrmel and Gonaives indicate that the boll weevil
(Anthonomus grandis Boh.) is gradually disappearing from the cotton planta-
tions. In some instances the weevils have punctured the petioles of the
bolls. They are apparently going under trash, as the harvest season cFo.e.e
to an end.

The last broods of cotton stainers, Dysdercus spp., are dwindling
away in the advanced cotton fields of the Cul de Sac plain.

Citrus whiteflies (Aleurodidae) have been observed in connection
with the green scale (Coccus viridus Green) and sooty mold around Petion-
ville.

The onion thrips (Thrips tabaci Lind.) has become quite abundant in
gardens of the Port au Prince district.

The first generation of Feltia annexa Treit. has appeared in newly
planted fields of potatoes on the Riochelois ridge, attacking tubers at 10 cm
below the surface.

Crickets, Gryllu sp., have been observed cutting the tender budi of
roses in the vicinity of Fort au Prince.

G. N. Wolcott reported on April 10, that a serious and destructive
outbreak of the onion thrips (Thrips tabaci Lind.) has recently developed and
threatens to destroy almost the entire crop on the extensive plantings of
onions, made in many parts of the island by the Relief Administration.

eliminates all possibility of control.

Mr. Wolcott also reports that the present dro-iht is responsible f'r
the appearance of the cottony-cushion scale (Icerya purchase Mask.) in
noticeable abundance at various points in the previously infested area, but
none of the citrus growers cor.nlg to the laboratory for a supply of Rodolia
cardinalis Muls. to release in their groves, report a heavy infestation*
The scale has spread very little, not yet (April 10) haVin,-' reached V-g!.

F. C. Bishopp reported on April 16 that specimens of flies sent to
the Bureau by H. L. Van Volkenberg, parasitologist of the Puerto Pico Agricul-
tural Zxr-riment Station at Mayaguez, have been identified as Cochliomyia
americana Cushing and Patton. This is the species that has recently caused
so much dimje to livestock in the Southeastern States. Thile the fly is
known to be present on other islani.z in the West Indies, this is the first
authentic record of its occurrence in Puerto Rico.

By
0. C. McBride

cotton bolls have just reached the stage for infestation by the pink
bollworm (pectinophora gossypiella SLund.). Approximately 90 percent of
the bolls are infested, the infestation ranging from one to seven larvae per
boll. Parcsitization (by 7 species of parasites) is quite low. Cotton
from ;laianoe, Oahu, shows less than 0.5 percent parasitization and from Hono-
lulu about 1 percent.

Although fruits were scarce during ;::rch,the abundance of the !editer-
renean fruit fly (Ceratitis capitata Wied.) in citrus and mango orc'.:r s in-
creased 50 percent over February. Parsistization at this season is v-ery
low--approximately 10 percent.

Reports indicate that the melon fly (Fectrocera cu-urbitap Coq.) is
doing considerable damage to Chinese cucumbers. Growers are trapping and
covering fruits for protection.
