Abstract:
The field experiment was carried out during Kharif and Rabi season of 2022-2023 at Agricultural and Horticultural Research Station, Bavikere, Keladi Shivappa Nayaka University of Agricultural and horticultural Sciences, Shivamogga, Karnataka, India. A total of 6 hymenopteran parasitoid species viz., Campoletis chlorideae Uchida, Chelonus formosanus Sonan, Cotesia ruficrus (Haliday), Trichogramma chilonis Ishii, Telenomus sp. and Eurytoma sp. representing 5 families and 6 subfamilies were recorded on fall armyworm from three different maize ecosystems. Among different ecosystems, both the number of families and species of hymenopteran parasitoids were found higher in organically grown maize than those found in other ecosystems. Trichogramma chilonis was dominant during Kharif season with a total relative frequency of 85.00% whereas, during Rabi season, Telenomus sp. was dominant with a total relative frequency of 60.50%. Organically cultivated maize had the highest diversity of parasitoids, followed by naturally grown and farmers’ practice.
