Abstract
Orius strigicollis (Poppius) and O. laevigatus (Fieber) (Heteroptera: Anthocoridae) can be reared successfully using a plastic Petri dish (90 mm in diameter, 20 mm in depth) as a rearing cage with wheat grains to prevent cannibalism and excessive moisture. Frozen eggs of Ephestia kuehniella were supplied as food and a soybean seedling was provided as an oviposition substrate. The rate of individuals reaching the adult stage averaged 74–87% when the initial nymphal density was 100–400. In addition to the high breeding capacity, these insects could be separated without difficulty from wheat grains by using a suitable sieve, and wheat grains were reusable after sterilization in an oven.
