Abstract

Competition between Corcyra cephalonica (Stainton) and Ephestia cautella (Walker) was studied in broken cocoa beans using the two species alone, introduced one before the other and together. Both species of moths cannot co-exist for an extended period and in competition E. cautella becomes extinct. The results offer an explanation of recent evidence that C. cephalonica is rapidly becoming the most important pest of stored cocoa beans in Ghana today.

Résumé

La concurrence entre Corcyra cephalonica (Stainton) et Ephestia cautella (Walker) a été étudié dans les graines de cacao concassées en n'utilisant que les deux espèces, en introduisant un avant l'autre, et en introduisant les deux en même temps. Les deux espèces ne peuvent pas coexister pour une longue période et quand ils sont en concurrence, E. cautella disparaît. Les résultats expliquent la preuve récente que C. cephalonica est en train de devenir l'insecte le plus important, ravageur de graines de cacao emmagasinées au Ghana.
