Malathion Resistance in Larvae of Some Southern Minnesota Populations of the Indianmeal Moth,\u3ci\u3e Plodia Interpunctella\u3c/i\u3e (Lepidoptera: Pyralidae), Infesting Bulk-Stored Shelled Corn

Larvae of 21 field collected populations of the Indianmeal moth, Plodia interpunctella, infesting stored shelled corn in southern Minnesota were tested for their susceptibility to malathion in the laboratory. A population that was a composite of the 21 populations and a malathion susceptible population were also tested for their susceptibility to malathion, pirimiphos-methyl and chlorpyrifos-methyl. Comparison of the LDso values of the field populations with the malathion susceptible population indicated that the field populations were ca. 33- to 625-fold resistant to malathion. The composite field population was ca. 243-fold resistant to malathion, and this population was 3.2-fold cross-resistant to pirimiphos-methyl, but was highly susceptible to chlorpyrifos-methyl

The Relative Effectiveness of Five Candidate Fumigants to Stored-Product Insects

Excerpts from the report: Fumigations were conducted in 19.5-liter bottles to determine the relative toxicity of certain fumigants to adult confused flour beetles, Tribolium confusum Duv.; adult sawtoothed grain beetles (Oryzaephilus surinamensis (L.); adult cigarette beetles, Lasioderma serricorne (F).; and black carpet beetle larvae, Attagenus piceus (Oliv.). The evaluation of promising new fumigants for use on raw and processed agricultural commodities is part of a broad research program aimed at developing more specific insect control methods that are safer to the handler and to the consumer
