Abstract

Bromophos (Nexion), 5 other organophosphorus and 2 organochlorine insecticides were tested as dry films in the laboratory in India for their toxicity to the stored grain pests Sitophilus oryzae (L.), Tribolium castaneum (Hbst.), Rhyzopertha dominica (F.) and Callosobruchus chinensis (L.). Dichlorvos (DDVP) was the most and malathion the least toxic to all 4 test insects, and S. oryzae was the most susceptible and R. dominica the most resistant species to all the test insecticides. In tests of the synergistic effects on bromophos of sublethal amounts of the other insecticides, only 3 compounds with a structure similar to that of bromophos (malathion, parathion-methyl and fenitrothion (Sumithion)) had marked synergistic effects.
