Abstract
In experiments with insecticides applied against first-instar pink bollworms, Pectinophora gossypiella (Saunders), coverage of green bolls with the deposits was important to effectiveness of the insecticide applications. Guthion® (O, O-dimethyl S-(4-oxo-1,2,3-benzotriazin-3-(4H)-yhnethyl) phosphorodithioate) and Sevin® (1-naphthyl N-methylcarbamate) were more effective than DDT in controlling these larvae. In studies of larval dispersal, newly hatched larvae moved up and down plants principally along the main stems. Most of the larvae that hatched on firm, green bolls, however, apparently did not disperse but entered the boll on which they hatched.
