Biology, morphology and seasonal population dynamics of mango leaf cutting weevil, Deporaus marginatus (Pascoe) (Coleoptera: Attelabidae)

Detailed study revealed that the life cycle of D. marginatus from egg to adult stage lasted for 19.1 ± 2.17 days with nearby 55 days from egg to egg with 96.17 ± 3.07% hatchability. The grub passes through three instars in fallen cut leaves. Data on population dynamics revealed the fact that the seasonal population progression of D. marginatus was synchronized with initiation of new leaves in grafted young plants in nursery in the month of June to October.
