Physiological Status Of Male And Female Popillia Japonica (Coleoptera: Scarabaeidae) Affects Mating And Grouping Behavior, Natasha Tigreros, Rashmi Jadhav, Katelyn A. Kowles, Britto P. Nathan, Paul Switzer
Paul V. Switzer
Because mating may be costly, sexually active males or females are predicted to be in relatively good physiological condition and may preferentially direct their mating behavior toward relatively high-quality mates. We tested this hypothesis in Japanese beetles (Popillia japonica Newman), a pest species in which males and females may be either isolated or in aggregations while feeding on host plants. We examined male size and lipid content and female size and egg load with respect to both their pairing status and whether they were isolated or in aggregations. Males that were paired had the highest lipid levels, and single, isolated …
