Islam, W. | Kabir, S.M.H.
Anisopteromalus calandrae (How.) parasitizing larvae, pre- pupae, and pupae of pulse beetle Callosobruchus chinensis (L.), was reared at 5 constant temperatures (18-35 deg. C) and 4 relative humidities (30-90%) to determine their influence on the developmental periods and progeny production. Relative humidity and temperature played a significant (P0.001) role on the development and progeny production. Male A. calandrae emerged earlier than females at all temperature and humidity combinations. At low humidities (30 and 50%) and temperatures (18-27 deg. C) the developmental period increased producing fewer progeny, while, at higher humidities (70 and 90%) and temperatures (31 deg. C) developmental period decreased producing more progeny.
