Abstract

Adult Typhaea stercorea were collected in Livingston County, Ill., from stored corn treated with pirimiphos methyl. When compared with a susceptible population exposed for 14 d to insecticide residues on corn in laboratory bioasasays, the Livingston County population exhibited 38-fold resistance to pirimiphos methyl and 66-fold resistance to malathion at the LC50. A laboratory colony of red flour beetle Tribolium castaneum showed resistance to malathion but not cross-resistance to pirimiphos methyl. A laboratory colony of maize weevil Sitophilus zeamais was susceptible to both insecticides. -from Authors
