Observations on Muscidifurax zaraptor Kogan & Legner and Nasonia vitripennis (Walker) (Hymenoptera Chalcidoidea Pteromalidae) parasitoids of Musca domestica L.

Abstract

Influence of temperature and humidity on development and on search capability and parasitization of Musca domestica pupae, at different depths of organic clay loam, of Muscidifurax zaraptor Kogan & Legner and Nasonia vitripennis (Walker) was studied. Developmental period is longer at 20°C than at 27°C in both species. The mean developmental period of M. zaraptor is not significantly different varying r.h. (40-60-80±5%). N. vitripennis has similar behaviour, except at 20°Cand 40±5% r.h.. M. zaraptor shows a greater ability than N. vitripennis in locating and parasitizing M. domestica pupae at different depths (1, 2, 3 cm).
