Abstract
The stem weevil, Hyperodes bonariensis Kuschel, was reared from egg to adult for eight generations on an artificial medium. At 26±0.5°C, 55±5% RH, and 12‐h photo‐period, development time from newly hatched larva to adult averaged about 28 days. There were four larval instars lasting about 14 days, followed by prepupal and pupal stages lasting a further 14 days. Oviposition occurred 2 weeks after adult emergence; mated females laid viable eggs. Ovarian diapause in some females was also noted. It is possible to rear about six generations a year under these conditions.Keywords
