Abstract
This study investigated the impact of constant temperatures (-15°C, 7°C, 28°C, and 35°C) on Callosobruchus chinensis L. (Chrysomelidae: Coleoptera). The results indicated that temperatures outside the control temperature of 28°C i.e. (-15°, 7°, and 35°C) significantly affected the biological parameters of C. chinensis. Specifically, adult emergence and egg hatching rates were most favourable at 28°C compared to the other temperatures tested. These findings emphasize the temperature sensitivity of C. chinensis and highlight 28°C as optimal for its developmental processes.
