Stages In The Life Cycle Of A Predatory Stink Bug, Stiretrus anchorago (Fabricius)

Stiretrus anchorago (Fab.) is a medium-sized predatory stink bug which preys on both coleopterous and lepidopterous larvae, and has been taken on soybeans, peanuts, alfalfa, and corn. It is predatory on the larvae of the Mexican bean beetle, Epilachna varivestis Mulsant (Howard and Landis, 1936; Waddill and Shepard, 1974, 1975; Deitz et al., 1976) the alfalfa weevil, Hypera postica (Gyllenhal) (Richman, 1977), and at least one lepidopterous species, Eurema nicippe (Cramer) (Richman and Whitcomb, 1978). In the laboratory it has been successfully reared on larvae of the Mexican bean beetle (Waddill and Shepard, 1974, 1975), the cabbage looper, Trichoplusia ni (Hubner), and the soybean looper, Pseudoplusia includens (Walker) (Richman and Whitcomb, 1978).
