Abstract

Tasmanian lacewing Micromus tasmaniae (Walker) is an important predator of many aphid species This study investigated the effect of four photoperiods on predation development and oviposition of M tasmaniae in the laboratory at 21 1C and 60 RH Results indicated that no individuals entered diapause at either immature or adult stage At each photoperiod late instar larvae consumed significantly more aphids than early instar larvae (P<00001) Developmental period of M tasmaniae from egg to adult was significantly shorter at 240 and 168 h (lightdark) than at 1212 and 024 h (P<00001) Pupal mortality was significantly lower at 168 and 1212 h The reproductive period decreased significantly with increasing day length However fecundity and fertility were significantly higher at 168 and 1212 h (P<00001) The sex ratio was malebiased with no significant difference between photoperiods The significance of these results in the understanding of foraging behaviour and mass rearing is discussed
