Three insecticides, malathion, chlorpyriphos-methyl, and pirimiphos-methyl were tested by using a discriminating dosage technique with impregnated filter papers. Mortality percentages were determined at the discriminating doses of insecticides. In Sitophilus spp. and Triboliim spp. discriminating doses for malathion and pirimiphos-methyl were used based on the IRAC susceptibility test method No:006. The others were used depending on the reference discriminating doses. The results obtained in these bioassays suggest that there was no insecticide resistance for chlorpyriphos-methyl in all tested species. For malathion, there was also no resistance other than Ankara strains of T. castaneum, S. zeamais and Karaman strains of S. zeamais. For pirimiphos-methyl, only the Ankara strain of R. dominica had resistance. Monitoring of resistance is important to adopt proper control measures for pest management for stored product pests.eninfo:eu-repo/semantics/closedAccessstored-product pestsinsecticide resistancemalathionpirimiphos-methylchlorpyriphos-methylArticle18555A185224WOS:000363071400013Q4
