“…The rice moth Corcyra cephalonica Stainton is an important insect-pest of different stored products in tropics (Jyoti et al, 2017) [4] . In India, this pest is being utilized in bio-control research developmental units for mass production of number of natural enemies which includes both parasitoids and predators (Jalali and Singh, 1992, Jyoti et al, 2017) [3,4] . Helicoverpa armigera is a major pest of many economically important crops including cotton, pigeon pea, chickpea, sunflower, tomato, sorghum, millet, okra, and corn in India, (Manjunath et al, 1989) [6] .…”
