Total Lipid and Fatty Acid Composition in Male and Female Larvae of Indian-Meal Moth and Almond Moth (Lepidoptera: Pyralidae)

The total body lipid and fatty acid composition of last instar larvae of the Indian-meal moth, Plodia interpunctella, and almond moth, Cadra cautella, reared on a turkey mash diet was determined. Male P. interpunctella larvae contained significantly higher (lA-fold) total body lipid than females, while no differences between the sexes of C. cautella larvae were observed. The relative abundance of the fatty acids palmitate, palmitoleate, stearate, oleate, lineoleate, and linolenate was similar in both sexes of P. interpunctella and C. cautella. The accumulation of individual fatty acids in larvae of both the moth species did not correspond to levels of fatty acids in the diet. The accumulation of palmitate, palmitoleate, and oleate in moth larvae of both the species was greater than linoleate and linolenate, suggesting a sparing effect by the former on the latter, more unsaturated fatty acids

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
