Abstract:
An experiment was conducted at Anand Agricultural University, Anand during 2022-23 to investigate different five inert materials viz., sand, saw dust, cow dung powder, rice straw ash and soil collected under the banyan tree @ 5 and 2.5 g/100 g of pearl millet seeds were tested for their efficacy in protecting stored pearl millet against Corcyra cephalonica (Stainton). Rice straw ash @ 2.5 and 5.0 g/100 g and cow dung powder @ 5.0 g/100 g pearl millet seeds were found the most effective against C. cephalonica as it achieved 93.46, 93.23 and 88.75% oviposition deterrence. Rice straw ash @ 5.0 g/100 g seeds was the most effective as 92.19% highest reduction of adult emergence, 6.07 days male longevity, 6.00 days female longevity and 32.43 eggs per female fecundity. The highest reduction of percent egg viability (44.67, 47.33%) was achieved by the treatment of rice straw at both doses’ levels. The sex ratio of males and females ranged from 1:1.00 to 1:1.06 in all the evaluated treatments. None of these inert materials tested at different doses hampered the germination of pearl millet during the storage periods up to 65 days.
