Abstract

Effects of spermatophore size on female remating were studied using the armyworm,Pseudaletia separata Walker, reared under isolated and crowded larval conditions. Females that received large spermatophores remated in lower proportion than those receiving small ones. Spermatophore size of the first mating was estimated by using mathematical models by He and Tsubaki (in press). Females reared in isolated conditions were more likely to remate than those reared in crowded conditions.
