Abstract

Life-fertility tables were described for Bracon hebetor Say (Hymenoptera: Braconidae) developing on the millet head caterpillar (MHC), Heliocheilus albipunctella de Joannis (Lepidoptera: Noctuidae). Mated B. hebetor females lived an average of 24.7 days, oviposited ca. 22 days, and produced 173.7 adult progeny with a 1:1 sex ratio. The estimated innate capacity of increase (rc) and net reproductive rate (R0) were 0.26 and 86.5, respectively. The mean generation time was 17 days.

Résumé

Les tables de vie et fécondité ont été décrites pour Bracon hebetor Say (Hymenoptera: Braconidae) se développant sur la mineuse de l’épi du mil, Heliocheilus albipunctella de Joannis (Lepidoptera: Noctuidae). En moyenne, les femelles fécondées de B. hebetor vécurent 24,7 jours, ont pondu pour une durée de 22 jours, et ont produit une progéniture de 173,7 adultes avec un sexe ratio de 1:1. Le taux d’accroissement (rc) de la population et le taux reproductif net (R0) étaient de 0,26 et 86,5, respectivement. La durée moyenne d’une génération était de 17 jours.
