Temperature-dependent development of immature stages of the western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)
Environmental Entomology 17 (2), 166-171
Abstract: Larval and pupal development of western corn rootworm was studied at eight constant temperatures ranging from 15 to 33°C. Development from hatch to adult stage occurred at 15-31.5°C; no larvae completed the second stage at 33°C. Adult survival decreased and wing deformities increased significantly at 15 and 31.5°C. Optimum development and survival occurred within the temperature range of 21-30°C. Males developed faster than females in all stages at temperatures from 18-30°C, but the sexes have a similar lower thermal threshold of development estimated to be near 9°C. The relationship between developmental rate and temperature was described for both sexes in all stages using linear and nonlinear equations. The information presented will facilitate the development of phenological models for this important pest species.
