Abstract:

A laboratory experiment was carried out in the Department of Entomology Agricultural College, Bapatla to know the resistance levels of malathion and deltamethrin against lesser grain borer, Rhyzopertha dominica and management with new insecticide molecule spinosad. The degree of resistant acquired by resistant population of R. dominica 3.80 folds resistant at LC50 and 2.61 folds resistant at LC99.9 level to malathion in comparison with laboratory susceptible strain at 72 HAT (LC50 = 0.0057 % and LC99.9 = 1.3337%). 1.60 folds resistant at LC50 (0.0345) and 3.83 folds resistant at LC99.9 (3.4338) level to deltamethrin, respectively in comparison with laboratory susceptible strain at 72 HAT (LC50 = 0.0215 % and LC99.9 = 0.8965 %). Insecticide tested for the management of malathion and deltamethrin resistant population of R. dominica, Spinosad was found to be the best at LC99.9 level with the relative toxicity (1.55 and 2.46 times) than malathion and deltamethrin respectively.
