Abstract

Preferences of Maruca vitrata (Fabricius) (Lepidoptera: Pyralidae) larvae to flowers, flower buds and pods of three different varieties of cowpea (IT 82E-666, IT 82D-716 and Botokpoyi) were studied in the laboratory using a four-branched olfactometer. For each plant part, fourth instars of M. vitrata were individually exposed to a set of three odours obtained from the cowpea varieties with pure air serving as the control. Movements of the larvae in the exposure chamber were followed at two levels of choice. Results from the first level of choice showed that the attractiveness of a particular plant part to M. vitrata larvae was not significantly influenced by variety. At the second level of choice a weakly significant preference was found for flowers (P = 0.1218) compared to pods (P = 0.7530) and flower buds (P = 0.6172). In all cases, no significant difference was found between the control (pure air) and the varieties.

Résumé

L'étude des préférences larvaires de Maruca vitrata aux fleurs, aux boutons floraux et aux gousses de trois différentes variétés de niébé (IT 82E-666, IT 82D-716 et Botokpoyi) a été faite au laboratoire à l'aide d'un olfactomètre à quatre bras. Pour chaque organe, des larves de quatrième stade ont été individuellement soumises aux odeurs des trois différentes variétés en plus de l'air pur qui a servi de témoin. Le déplacement de chaque larve a été suivi et deux niveaux de choix ont été établis: un premier choix et un choix définitif. Au niveau du premier choix, les résultats ont montré une absence de différence significative entre les variétés pour tous les organes: boutons floraux (P = 0.8260), fleurs (P = 0.8662) et gousses (P = 0.5724). Au niveau du choix définitif également, aucune différence significative n'était observée aussi bien pour les gousses (P = 0.7530), pour les boutons floraux (P = 0.6172) que pour les fleurs (P = 0.1218). Aucune différence significative n'était aussi observée entre le témoin (air pur) et les variétés dans tous les cas.
