Callosobruchus maculatus (Fabricius) (Coleoptera: Bruchidae) Oviposition Behaviour on Cowpea Seeds

  • T. I. Ofuya
Research Article


Egg distribution on cowpea seeds and the influence of seed population on extent of oviposition by Callosobruchus maculatus (F.) were investigated in this study. Majority of the eggs were laid on the cheek of the cowpea seeds. The number of eggs laid by females increased with increase in seed population. The results are discussed in relation to observations on oviposition behaviour of C. maculatus reported by earlier workers.
