It has been recorded from millet as a parasitoid of pyralid moth caterpillars ( i.e . Coniesta ignefusalis (Hampson) and Chilo zonellus (Swinhoe)) . Also this species has been reported as a pest of introduced high-yielding cultivars of sorghum, but not the variety “Baini” (Ba-angood & Hubaishan 1985 ).
