Egg-lying behavior of Anisopteromalus calandrae (Howard), an Ectoparasitoid of Lasioderma serricorne (Fabricius)

Abstract

This paper describes the egg-laying behavior and reproduction capacity of Anisopteromalus calandrae in laboratory conditions. Anisopteromalus calandrae lay eggs only on the Lasioderma serricorne larvae hiden inside of grains or nests. The maximum lifespan of A. calandrae females was 32 days when they were kept with of aqua feed flour plus honey (30%) and infested with larvae of Lasioderma serricorne. One female laid 71.13 ± 4.24 eggs. The eggs were laid mostly (81.95%) during the first half of the lifespan, with the peak of 7.40 eggs/day on the 9^th day. The females usually lay one egg/host larva, but sometimes they lay 2-5 eggs/host larva. They prefer to lay eggs on the 4^th larval instar.
