Abstract. The present research was aimed to study the biology of Caryedon serratus (Olivier) on groundnut,. Arachis hypogaea (L.) under. C. serratus infestation of groundnuts is revealed by larval emergence holes and the presence of cocoons outside the pods. Feeding damage to the seeds can be . Higher rates of infestation by the larvae of the seed weevil Caryedon serratus Olivier (Col., Bruchidae) were recorded. The larvae of C. serratus bore into the.
