ABSTRACT
In laboratory trials against oak defoliater, Gazalina
chrysolopha Koll.Three antimoultant chemicals-Atabron,
Alsystin and Dimilinin 0.04% concentration gave,
respectively, 95.90 and 85% larval mortality within 6
days while the insecticides Malathion and Sevin SP
killed 100% and Orthene 80% larvae in the same dose
within 24 hours. In lower doses of 0.01 and 0.02%
antimoultants caused 60 to 75% and insecticides 70 to
80% larval mortality in the same periods. The pest was
controlled by spraying Malathion 57% E.C. in
0.17% concentration on the resting caterpillars at the natural enemies of the pest.
