摘要：

Ageing and its affect on life attributes have not been widely explored in ladybirds The present study investigates the influence of female and male age at mating on the reproductive attributes of the ladybird beetle, Coelophoia saucia (Mulsant) All reproductive attributes, viz fecundity, percentage egg hatch, pre-oviposition, oviposition and post-oviposition periods were found to be influenced by the ages of both females and males at mating This is unlike the results of previous studies on ladybirds, where male age was found to influence only percentage egg hatch The influence of male age at mating on fecundity and reproductive periods is probably due to age influenced variation in seminal proteins, which influence fecundity and when the eggs are laid
