The leaf roll rate was shown to be higher as the pest population increased. Biochemical profile of rice leaves damaged by a leaf folder was studied for quantitative and qualitative variations in soluble carbohydrate, starch and the ratio of chlorophyll a/b using standard biochemical procedures. The tests were carried out on a susceptible rice variety TN1. The result revealed that with increase in infestation by C. medinalis resulted in decreased soluble carbohydrates and starch content in rice leaves. But the trend was different for chlorophyll a/b and the ratio was found higher in pest infested vegetation.

It was revealed that pymetrozine 50% WG 150 g a.i./ha proved to be the superior insecticide against brown planthoppers and white backed planthoppers exhibiting maximum per cent reduction over control followed by pymetrozine 50% WG 125 g a.i./ha. The least effective insecticide was imidacloprid 200 SL @ 25 g a.i./ha.

It was revealed that pymetrozine 50 % WG 150 g a.i./ha proved to be the superior insecticide against green leafhopper exhibiting maximum per cent reduction over control followed by pymetrozine 50 % WG 125 g a.i./ha. and the above chemicals did not exercise any adverse effect on the spider.
