Micromus tasmaniae Walker is an important predator of a number of economically important pests such as aphids The largerthebetter theory predicts that reproductive fitness is positively linearly associated with body size or weight To test whether larger insects perform better reproductively the insect population was divided into three weight groups light average and heavy and the reproductive performance of nine breeding treatments (three male weights three female weights) was assessed The body weight of female M tasmaniae had no significant effect on reproductive fitness in terms of fecundity fertility fertility rate oviposition period and longevity suggesting that female size variation is of secondary importance in determining reproductive fitness in this species Male size had significant positive effect on female fecundity fertility and fertility rate and reproductive period This suggests that heavy males may transfer larger ejaculates that provide more sperm and malederived nutrients to females than light males
