EFFICACY OF SOME COMMONLY USED INSECTICIDE ON THE RED FLOUR BEETLE Tribolium castaneum (HERBST) (Pages : 8 - 11)

The experiments were conducted in the laboratory of the Department of Entomology, BAU, Mymensingh during April 2002 to December 2002 to find out the resistance level of different insecticides by insect strains in Bangladesh. Wheat samples containing adult beetles were collected from 9 different locations of Bangladesh and then the collected insects were reared. Field strains of the red flour beetle, Tribolium castaneum (Herbst) (Tenebrionicae: Coleoptera) collected from eight storage depot and one silo, were tested for susceptibility to malathion, dichlorvos, fenitrothion, pirimiphos-methyl and phosphine. Results of discriminating dose tests of the red flour beetle indicated that all strains were resistant against all the test insecticides. Highest resistance was observed against malathion followed by dichlorvos, phosphine, pirimiphos-methyl and fenitrothion. Ghatail and Tangail populations of the beetle showed higher degree of resistance against malathion, Sheddirganj populations showed against dichlorvos and tangail populations observed against phosphine compared to other populations.
