Abstract: (5660 Views)
The ovipositiomil behaviour and success of Anagyrus pseudococci (Girault), an
encyrtid endoparasitoid of mealybugs, Planococcus citri (Risso) and Pseudococcus
affinis (Mask.) were studied in the laboratory. Behavioural sequences during
oviposition starting from the searching for the host to the post-oviposition activities
were described. Once encountered, the mealybug host was examined and probed by the
ovipositor of the parasitoid. Oviposition success was influenced by the defence activity
of the host. P. citri was less able to defend itself and was more susceptible to
parasitism than P. affinis. Oviposition experience of the parasitoid played an
important role in increasing the efficacy of subsequent oviposition.
