Morphological and population aspects of Diabrotica speciosa speciosa (Germar) (Coleoptera: Chrysomelidae) under laboratory conditions

Abstract

Diabrotica speciosa speciosa (Germar) is one of the most widely distributed chrysomelid in crops in Argentina. The morphology of preimaginal stages, life span and reproductive behavior were studied. The development were carried out under controlled conditions. Under these conditions the following population parameters were computed: generation time, reproductive rate, intrinsic rate of increase and an horizontal life table was made.
