Impact of Oviposition Sequence and Host Egg Density on Offspring Emergence and Interspecific Competition in Two Species of Parasitoids.

Asian corn borer (ACB), Guenee (Lepidoptera: Crambidae) and the rice moth (RM), Stainton (Lepidoptera: Pyralidae) are economically significant insect pests that threaten the agricultural products worldwide. parasitoids are successfully mass-reared using artificial host eggs, RM, and are often managed by economically important lepidopterous pests, such as ACB in China. Pang and Chen (To) and Matsumura (Td) (Hymenoptera: Trichogrammatidae) are two important parasitoids of ACB.
