ABSTRACT Development and longevity of Chelonus sukazus Nees, an egg larval parasitoid of the pink bollworm, Pectinophora gossypiella ( Saund. ), were studied at different constant temperatures. Successful development occurred at all tested temperatures between 20 and 35 °C . The developmental period was negatively correlated with temperature ; the shortest period was 21.9 days at 35 °C Female longevity reached a maximum of 30 - 7 days at 27 °C. |
