Abstract

Non-parametric statistics were used to describe the spatial distribution of eggs laid by Zabrotes subfasciatus Boh. (Coleoptera, Bruchidae) inside pods of wild Phaseolus lunatus and cultivated P. vulgaris. Eggs tended to be uniformly distributed among seeds inside the pods of P. lunatus whereas egg distribution patterns were random or aggregative inside P. vulgaris pods. These differences were explained in terms of the internal pod morphology of the two host plants. It was concluded that this bruchid normally oviposits uniformly among accessible seeds inside the pods of its host plants in the wild.

Résumé

Des tests non-paramétriques sont employes pour décrire la distribution spatiale des pontes de Zabrotes subfasciatus Boh. à l'intérieur des gousses de Phaseolus lunatus sauvage et de Phaseolus vulgaris cultivé. Les pontes ont tendance à ètre réparties de manière uniforme sur les graines disponibles dans les gousses de P. lunatus. Par contre, les distributions observées à l'intérieur des gousses de P. vulgaris sont aléatoires ou présentent mëme différents degrés d'agrégativité. Ces differences s'expliquent en termes de la morphologie interne des gousses des deux plantes hôtes. On en conclue que la distribution spatiale des pontes de ce bruchidé à l'intérieur des gousses contaminées est normalement uniforme dans la nature.
