Transgenerational effect on developmental attributes of insects has been studied extensively. The present study elucidates the role of diet on transgenerational developmental duration and reproductive attributes of Propylea dissecta (Mulsant). We have found a significant direct and transgenerational role of diet variations in feeding rhythms on the above attributes of P. dissecta. Dampened response was found in offspring fed on intermittent diet even when their parental generation was provided abundant food supply. Reduced reproductive attributes were found in the progeny of abundant diet parents reared on intermittent diet than the kin of the same abundant fed parents which were under other diet conditions.

Abstract


Transgenerational effect on developmental attributes of insects has been studied extensively. The present study elucidates the role of diet on transgenerational developmental duration and reproductive attributes of Propylea dissecta (Mulsant). We have found a significant direct and transgenerational role of diet variations in feeding rhythms on the above attributes of P. dissecta. Dampened response was found in offspring fed on intermittent diet even when their parental generation was provided abundant food supply. Reduced reproductive attributes were found in the progeny of abundant diet parents reared on intermittent diet than the kin of the same abundant fed parents which were under other diet conditions.
