_ Farmers anxious to cooperate in cotton flea hopper research.—- 
"There seems to be an unusual amount of interest in this locality" re- 
ports K..P. Ewing, Port Lavaca, Tex., "concerning our cotton flea hop— 
per investigations. We have been approached by numerous planters and 
indidivual farmers who offered their entire farms, or any portion of 
them, for any field experiment we may wish to conduct. We are well 
pleased with the apparent cooperation that we will have here in con- 
ducting our experiments." 
Little winter activity of boll weevil in Qklahoma.—-H. C. Young, 
Eufaula, Okla., reports that "Daily observations were made throughout 
the month (January) of the 70 hibernation cages installed last fall. 
During the month only 3 active weevils were observed; 1 on January 18, 
1 on January 19, and 1 on January 22. These active weevils were in the 
cages installed on October 15, 1932. Two were observed in the cages 
provided with corn stalks as hibernation shelter and 1 in a cage provi- 
ded with prairie hay. Even though the weather was unusually warm for 
this period of the year there was no marked tendency for the weevils to 
emerge from the material in the hibernation cages and crawl about on 
the wire." 
Merits of different methods of collecting pink bollworms for par- 
asite breeding.--L. W. Noble and L. C. Fife, Presidio, Tex., reporting 
on methods of obtaining pink bollworms for the breeding of the parasite 
- Microbracon brevicornis Wesm., state: "Part of the larvae in the cotton 
bolls collected in the fall spun up in the lint and the others inside 
the seed. When needed for parasite breeding, the larvae can be obtained 
by tearing the lint apart by hand and cutting the seed with a knife. 
This method would be rather slow for collecting a large number of larvae. 
Many of the larvae are injured in cutting the seed, but the uninjured 
‘ones cut out in January were in almost as good condition for parasite 
breeding as larvae collected in the growing season. This method, al- 
though slow and tedious, is believed to be preferable for parasite breed- 
ing to other methods principally used in biological work on the pink 
bollworm. It was found that the most successful method of securing 
overwintered pink bollworms in abundance for biological work in the 
spring was to soak infested seed in water and let the seed heat. The 
larvae became active, crawled out of the seed, and began pupation., This 
was desirable for the biological work but most of the worms were not in 
the best stage for parasite development. It has been observed in the 
laboratory that pink bollworms parasitized just before pupation began 
to decay after a few days and the parasite larvae died. Evidently the 
body content of the host at that stage was not suitable food for the 
parasites."

Ditch construction important in sand-fly control.--W. E. Dove and 
assistants, Savannah, Ga., who have been making studies of sand—fly lar- 
vae, report that "the storm tides of last autumn reduced the incidence
