A trial on chemical control of mango leaf hoppers (Idiocerus atkinsoni L. and I. clypealis L.)

Abstract

Different workers from time to time advocated different formulations of insecticides against mango leaf hoppers. An attempt was made to evaluate the efficacy of various insecticides against this pest. The authors have tried in their control experiments for two seasons (1958-59; 1959-'60) four insecticides, viz., DDT 50% W. P., BHC 50% W. P., Parathion (Ekatox 20% W. P.) and Endrin 20% E. The general belief of the workers in the use of Parathion is not favourable because it being a phosphatic compound is toxic to the operators and the workers engaged in the orchards. However, this fear seems to be baseless as the concentrations used are very light. What is required is a little care while spraying. It was successfully sprayed on the orchards without any adverse effects on the persons concerned. The purpose of using Endrin for jassids was simply to assess its efficacy as it is usually considered to be a good insecticide for controlling immature stages of insects. BHC also was tried for comparing its efficacy with the other insecticides mentioned in the above para.
