[The effects of different temperatures and diet on the longevity of Bracon hebetor (Say, 1836) (Hymenoptera: Braconidae)]
Turkish Journal of Entomology 34 (3), 351-360
Abstract: The effects of constant and varying temperatures from 18 ºC to 35 ºC and diet on longevity of Bracon hebetor (Say, 1836) (Hymenoptera: Braconidae) were investigated. Ephestia kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae) larvae were used as host. Adults were provided with one of the three food types: host larvae, honey solution (50%) or host larvae+honey solution. Temperature had a significant effect on the longevity of female and male parasitoids. The longest longevity of both sexes occured when adults reared at 18 ºC. Increasing the temperature from 18 ºC to 35 ºC decreased the longevity. Adults reared at fluctuating temperatures lived considerably shorter than those reared at 18 ºC and 25 ºC, but longer than at 35 ºC. Longevity also was significantly affected by diet in both sex of parasitoid. Honey feeding to adult parasitoids increased their longevity. They lived the longest at 18 ºC and the shortest at 35 ºC. Females fed with all food types in different temperatures lived longer than males.
