Food characteristics strongly regulate digestive enzymatic activity of insects through direct influences on their midgut mechanisms. Insect performance is better on diets that contain nutrients in proportions that fit its digestive enzymes. Little is known about the influences of rearing history on parasitism success of Habrobracon hebetor Say. This research focused on the effect of nutrient regulation on survival, development, and parasitism of H. Life history and digestive enzyme activity of fourth-stage larvae of H.

Mating duration did not differ significantly among different successive matings with different females and had no effect on the rate of parasitism.

In general, pairs that had their copulation early after emergence exhibited the maximum rate of parasitism as compared to delayed intervals. Moreover, the age of the H. The maximum parasitism percentage was recorded for the H. The male: female ratios did not differ significantly among the female age groups.

The percentage of parasitism clearly indicated a decrease with the increase of the male: female ratio. Overall, the results of the present work can be further utilized in mass rearing and release of H.

Heliocheilus albipunctella de Joannis Lepidoptera: Noctuidae is one of the major insect pests of pearl millet in the Sahel. The native parasitoid, Habrobracon hebetor Say Hymenoptera: Braconidae , is currently being promoted for augmentative biological control of the pest in the Sahel. The current study was carried out to identify the right time for releases of the parasitoid using either pearl millet growing stage, or pest occurrence as reference, and to determine the optimal number of parasitoids needed to cover a given area.


Habrobracon hebetor (Say, 1836)

Habrobracon hebetor is a minute wasp of the family Braconidae that is an ectoparasitoid of several species of moth caterpillars. Well known hosts include the larval stage of Plodia interpunctella , the Indian mealmoth , the late larval stage of the Mediterranean flour moth and the almond moth , and the dried fruit moth Cadra calidella [4] [5] This parasitoid has been used commercially as a way to control pests without using chemical insecticides. These wasps feed quickly, aided by their gut enzymes which quickly destroy the blood proteins in the moth larvae. This increases the value of the species as an effective biocontrol agent. The adult female lives about 23 days during which it produces about eggs.
