| Inhoud: |
The mymarid Anaphes n.sp. was observed to parasitize the eggs of the carrot weevil Listronotus oregonensis (LeConte) up to 138 h old at 23±1°C and 18L:6D. Adult emergence of the parasitoid was observed in 85%-97.5% of the weevil eggs 42-138 h old and host embryogenesis was interrupted in nearly 100% of these eggs. In host eggs of 18 h old, parasitism was very high but not all parasitoids completed their development and their subsequent emergence was generally retarded. An.sp. could parasitize host eggs 162 h old, but such an attack rarely retarded the normal development of the host. The parasitoid was unable to complete its development in sterile carrot weevil eggs. |
