Abstract

Eggs from field-collected Glyptotendipes paripes Edwards were hatched and the immature life stages individually reared under 11 constant temperatures between 10.0 and 35.0°C (2.5°C increments) in the laboratory. No egg hatch was observed at 10.0°C for up to 30 d. At 35.0°C, egg hatch was normal but the larvae did not survive to second instar. The developmental zero growth was estimated at 9.0°C. Degree-day requirement for G. paripes development from egg to adult was estimated at 717 DD above 9.0°C. No significant difference between development time of males and females was noted and the sex ratio was near 1:1.
