Induction of Adult Diapause by Photoperiod and Temperature in Protophormia terraenovae (Diptera: Calliphoridae) in Japan

Abstract

The incidence of adult diapause was examined in Protophormia terraenovae (Robineau-Desvoidy) in the strain from Obihiro, Japan, under various photoperiodic and temperature conditions. Although at 30°C no adults entered diapause in either long-day or short-day conditions, between 17.5 and 27.5°C the insect showed a long-day photoperiodic response. The incidence of diapause was higher at lower temperatures under both long-day and short-day conditions.
