In the present study, immediate and trans-generational effects of parental diets (i.e. abundant and scarce) were investigated in a ladybird beetle Anegleis cardoni (Weise). Prey scarcity prolonged pre-oviposition period and reduced fecundity and egg viability. Reduced survival and developmental rate of progeny was recorded under prey-scarce conditions. The progeny of parents reared under prey-scarce conditions developed more slowly than that of those reared under prey-abundant conditions, regardless of the progeny diets. This study indicates the existence of parental diet effects on progeny survival and developmental attributes.
