Abstract
AbstractThe premating period in the parasitoid Priopoda nigricollis (Thos.) is about 2 days, and females are receptive for up to 4 days, after which time the oviducts contain mature eggs. Copulation behaviour in specially built chambers, and oviposition pattern are described. The structure of the ovaries is illustrated. Host feeding by adult P. nigricollis was observed, but it is not a prerequisite for initial egg maturation. Hosts are located by random stabbing with the ovipositor into the mines of Fenusa pusilla (Lep.). Data on the age-specific fecundity of this parasite in laboratory experiments are given. The importance of liberating mated parasite populations is emphasized for successful biological control.
