study of weevils collected on the field screens and the wocds screens 
(located in pasture land between cotton fields and timber) for the 
three winter months, January, February, and March, is the difference 
in the average number of weevils for these screens. During the ihree 
months 980 weevils were collected on the 24 field screens, or an av-— 
erage of 24.1 weevils rer screen. On the two woods screens 25 weevils 
were collected, or 12.5 weevils rer screen. Apparently the weevil 
‘ movement was much greater within the fields than between cotton fields 
and timber." 
Cotton leaf rerforator active all winter.—-Notes by T. C. Barber, 
show that "ithe development of the species continued through March, in 
the same manner that it had been doing during the remainder of the win- 
ter months, Since cotton planting was well in progress during March, 
and considerable cotton had already sprouted, it has thus been proved 
that active development occurred right through the winter of 1931-32 in 
the Lower Rio Grande Valley of Texas." 
INSECTS AFFECTING MAN AND ANIMALS 
Community trapping of eye gnats effective.—-D. C. Parman, reporting 
on control of Hippelates spp. at Coachella, Calif., says:"Community trap-— 
ping was first started with approximately 75 of the small box jar traps 
at the Coachella Valley High School in the early spring of 1930 * * * 
This test was continued through the summer and a high percentage of ccn- 
trol was indicated. In the fall of 1930 the large box trap with a wind— 
Mill bait agitator was developed and installed at the laboratory and an- 
Other larger trap of the same type was installed at Indio. In March, 
1931, the Coachella Valley Abatement District had 18 of the large traps 
constructed and these were installed at the six schools in the valley 
in March or the first of April. Those traps apparently gave a high 
percentage of control of eye infections in the schools last year. The 
traps were installed and serviced by the Bureau of Entomology until 
July 1, 1931, when the servicing was taken over by the Abatement District 
and has teen continued, and 21 more traps will be installed at an early 
date. * * * using the status of March (the month indicated by the status 
as having the high peak of abundance of gnats), 1950, as a basis, there 
See control of 67 per cent in 1951, and 96 per cent for 1962. * * 
While scme trapping has been done by individuals it is indicated that 
the greatest decreases have been in the vicinities of the systematically 
serviced traps of the Abatement District." 
Creosoted pine sap kills house fly larvae.--W. E. Dove reports 
that "During the mild winter just past, house flies continued to breed 
at the city dumping ground. On the first of February they were very 
annoying in buildings at Charleston (S. C.). At the city dump millions of 
flies were present. The indiscriminate practice of dumping garbage mixed 
with pager along the edges of the dump resulted in the presence of Leavy 
‘nfestations of larvae." Mr. Dove and his assistants used a power s>rayv—
