Description The effectiveness of the egg parasitoid
Trichogrammatoidea armigera Nagaraja (Hymenoptera:
Trichogrammatidae) in controlling Heliocheilus
albipunctella de Joannis (Lepidoptera:
Noctuidae), a major insect pest of pearl millet in the
Sahel was assessed during two consecutive years in
Niger on-station and on-farm conditions. We found
that released T. armigera were able to find and
parasitize host eggs within pearl millet fields both onstation
and in farmers’ fields. On-station releases of T.
armigera led to an average 4.86-fold increase in T.
armigera parasitism compared to control fields, where
no parasitoids were released. Likewise, on-farm
releases of T. armigera led to up to 5.31-fold more
egg parasitism by T. armigera in release fields than in
control. Our results suggest the effectiveness of T.
armigera and lays the groundwork for using T.armigera in augmentative biological control of H.
albipunctella in the Sahel.
