Influence of parental age on reproductive performance of an aphidophagous ladybird, Propylea dissecta (Mulsant)
Journal of Applied Entomology 128 (9-10), 605-609
Abstract: In the present study the influence of maternal and paternal ages on reproductive performance of an aphidophagous ladybird, Propylea dissecta (Mulsant) were investigated. Maternal age strongly influenced fecundity and pre-oviposition period while paternal age strongly influenced the egg viability. Maternal age also influenced percent egg viability, however, at lower levels of significance. The results revealed that the fecundity and percent egg viability increased up to the respective maternal and paternal ages of 30 days and thereafter declined, indicating the onset of senescence. The results of the present study can help in better mass multiplication of the ladybird concerned and in laying foundation for further age-related studies.
