Oviposition behavior and development of Goniozus triangulifer Kieffer (Hymenoptera: Bethylidae)

Bionomics and behavior of the bethylid parasitoid, Goniozus triangulifer Kieffer, were studied in the laboratory with leaffolders, Cnaphalocrosis medinalis (Guenee) and Marasmia patnalis (Bradley), as hosts. Female parasitoids lived twice as long as males (22 and 11 d, respectively) and laid about 80 eggs during their lifetime. Single male broods occurred in 64% of the samples and were significantly more frequent than expected from the binomial distribution only when the brood size was six. Females exhibited complex behavior upon encountering a host.
