Abstract

Simple methods for production of all life stages of the banana weevil on its natural diet, banana rhizome and pseudostem are presented. Their effectiveness, labour demands and applicability for different purposes are discussed. The most effective method for the production of eggs, pupae and adults is the utilization of the rhizome part of suckers, whereas larvae are easier to recover from pseudostem. The hatchability of the eggs produced is high.

Résumé

Des méthodes simple sont présentées pour la production de tous les stades du charançon du bananier dans son régime naturel, le rhizome et le pseudotronc du bananier. Leur effectivité, dépense en temps et applicabilité pour des objectifs differents sont discutées. La méthode la plus effective pour la production d'oeufs, de pupes et d'adultes est celle utilisant le rhizome des rejets, tandis que les larves sont plus facilement récupérées du pseudotronc. Le pourcentage d'oeufs éclorants est élevé.
