Abstract

The oviposition behavior of the West Indian Sweet Potato Weevil, Euscepes postfasciatus FAIRMIRE was observed in the laboratory. Oviposition behaviors were composed of searching for an egg-laying site, resting, excavating an egg-laying hole with mouthparts, ovipositing into the hole, lidding the egg-laying hole with feces, and resting after ovipositing. The size of the egg, features of the egg-laying hole and the fecal lid were also noted.
