Abstract

Malacosoma americanum (Fabricius) (Lepidoptera : Lasiocampidae), the Eastern tent caterpillar, is a pest native to the United states. It is particularly injurious to apple, cherry, and other fruit trees, but can be destructive to other deciduous trees. Control of this pest is difficult, largely because of its congregation behavior.

Abstract

The evaluation of treatments in the control of Spodoptera litura (Fab.) was done under leaf dip method (poisoned food technique). All the treatments were found significantly superior over control. Among treatments the highest larval reduction of 90.00% to 100.00% was recorded with the treatment comprising of DDVP (0.05%) and DDVP (.025%)+NSKE+cow urine 2% and minimum larval reduction 20.00% to23.333 was recorded after 24, 48 and 72 hours, and mortality at 72 hours was highest over 48 hours and 24 hours.
