Thirty-nine selected peanut (Arachis hypogaea L.) genotypes from a diverse germplasm collection with known resistance and susceptibility to preharvest insects were tested in the laboratory for postharvest resistance to the Indian meal moth, Plodia interpunctella (Hubner), and the almond moth Cadra cautella (Walker). After the initial test the number of genotypes was reduced to 20 to reduce duplication of pedigree and omit some of the genotypes with intermediate resistance. Additional data were collected from the 20 genotypes on ovipositional preference and larval establishment on shelled and unshelled (farmers stock) peanuts.

Genotypes with resistance to moth species included NC 6, GP-NC 343 × NC 5, PI 467307, NC 7 × NC 10247, GP-NC 343 × NC 17367 and breeding line 10-P10-B1-B1-B1-B1-B2. Resistance to preharvest and postharvest insect complexes suggest some common chemicals may be present in the green crop and the harvested seed that elicit ovipositional response.
