Abstract

Life-fertility tables were described for Bracon hebetor Say (Hymenoptera: Braconidae) developing on the millet head caterpillar (MUC), Heliocheilus albipunclella 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 (ir) and net reproductive rate (R0) were 0.26 and 86.5, respectively. The mean generation time was 1 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.
