| In this study ultraviolet (UV) radiation was used to test for increasing the production of the ectoparasitoid Bracon hebetor (Say)(Hymenoptera: Braconidae) by improving the suitability of host larvae (Ephestia kuehniella Zeller, Lepidoptera: Pyralidae). Both the host larvae and the adult parasitoids were exposed to UV radiation between 0 and 70 min at eight levels. Variations in the number of developmental stage and number of adult emergence were used as criteria to evaluate the UV radiation effects. Following host larvae exposures to radiation, the number of eggs laid by B. hebetor as well as the number of larvae, pupae and adults emergence were not influenced. An increase in time of exposure to UV-radiation caused a significant decrease in the number of eggs laid by B. hebetor. No adult emergence occurred after 40 minutes of exposure in eggs and larvae of B. hebetor from the host larvae. B. hebetor pupae and adults were less sensitive to UV-rays than were its eggs and larvae. Developmental stages and adults of B. hebetor are more sensitive to ultraviolet radiation than the host larvae. The results obtained from this test demonstrate that the use of an irradiated host does not have any negative effect on parasitoid development. |
