The cotton blister mite (Eriovhyes gossypii Banks) attacks any 
part of the cotton plant above ground, although its attack upon the 
fruiting parts is confined to the bracts. It causes wartlike pro- 
tuberances and plants attacked are considerably dwarfed, or may be 
entirely killed. Damage is very localized and plants within a few 
yards of severely attacked plants were not injured, Its distribu— 
tion.in Florida is "spotted" in the southern part of the peninsula, 
and up the west coast to Punta Gorda and along the keys. It is known 
to occur in Martinique, Nevis, Barbados, Puerto Rico, and the Virgin 
Islands. 
The larvae of a cotton leaf miner (Nepticula gossypii Forbes and 
Leonard) make sharply angulated mines in the leaves, causing them to 
fall, and also mine the bracts of the squares, blooms, and bolls; 
A heavy infestation causes severe shedding of foliage. This miner was 
previously known only from Puerto Rico, where it was described in 1930. 
It is nct generally distributed in Florida but is found on the 6xtreme 
tip of the peninsula, on the numerous keys, and around Fort Myers. 
Anonis impasta Guenee has been reported on cotton from Brazil, 
Barbados, end Cuba. It was reared from a wild cotton blossom taken 
on Long «cy, Fla., but its importance as an economic insect seems 
negligible.

The above-named five species are discussed in the order of their 
importance as found on wild cotton in Florida. The first four seem 
worthy of consideration as of potential economic importance. 

Boll weevil control tests at Florence, S; C,, in 1934.--Foeme 
Bondy reports that eight treatments or combinations of treatments 
were used, duplicated from 2 to 6 times, on 54 plats of approximately 
l acre each, The plats were laid out as 15 two-plat tests, one Groecaaae 
and one untreated check; and 8 three-plat tests, two treated, and one 
check; all. together, 31 treated plats and 23 check plats. In the 
table below the different treatments are averaged and the gain or 
loss based on the average yield of the corresponding checks,
