Abstract
The rice weevil (Sitophilus oryza (L.)) is known to infest standing corn in the field in Louisiana. It was not known at what maximum grain-moisture level oviposition followed by complete development occurred. Studies conducted over a 2-year period showed oviposition may occur at a grain moisture of 65%. Eggs laid at this stage of corn maturity required 9 days for incubation. Complete development from egg to emergence of the adult required 42 days, and occurred between a grain moisture change from 65% to approximately 25%.Keywords
