Fourteen strains of Sitophilus zaemais and fifteen strains of Rhizopertha dominica, collected from rice warehouses and farmers' storage facilities throughout Indonesia were tested for resistance to malathion and pirimiphos methyl. Two strains of S. zeamais showed a slightly resistant response to malathion, while all strains of this species were susceptible to pirimiphos methyl. Resistance of R. dominica to malathion was detected in three out of the fifteen strains tested. The predominant species of Sitophilus was S. zeamais.
