Abstract

The results are reported of studies made at the SFS College-cum-Research Centre at Burnihat, Assam, in 1980-82, on Lohita grandis, a pest of Trewia nudiflora, Bombax ceiba [B. malabaricum], Gossypium herbaceum and Hibiscus esculentus [okras]. L. grandis is widely distributed in the warm and humid forest areas of NE India. The biology and life cycle of the pest are described, and the results presented of laboratory tests with 10 insecticides: carbaryl, Dursban (chlorpyrifos), quinalphos, M-parathion [? parathion-methyl], monocrotophos, endosulfan, fenitrothion, dichlorvos, dimethoate and DDT. Carbaryl, followed by chlorpyrifos, were the most effective insecticides.
