Effect of maize grain diet and egg density on the development and emergence of Corcyra cephalonica (Stainton)
Author(s): Mahavir Malik
Abstract: The milled grains of maize (Zea mays L.) prepared to rear and maintain the rice moth, Corcyra cephalonica under laboratory conditions. Each culture containing 225 g of grains were infested with 375, 750, 1125, 1500 freshly (0-24 h old) eggs of C. cephalonica. Adult emergence of C. cephalonica was highest 91.31 per cent from the egg density of 375 eggs/225 g maize while lowest emergence 36.15 per cent of rice moth was from egg density of 1500 egg/225 g grains. The peak emergence from grains infested with egg density of 375 eggs/225 g grains occurred during 51-60 days after infesting the grains, but with 1125 and 1500 eggs density, the peak emergence was 81-90 days after infesting. The first and last moth emerged with egg density of 375 and 750 eggs/225 g grains was 30 and 131, 31 and 141 days, respectively, after infesting the grains. In case of egg density of 375 and 750 eggs/225 g grains 50 and 80 per cent of moth emergence was observed up to 60 to 70 days and 70 to 80 days, respectively after infesting the grains. While with the egg density of 1125 and 1500 eggs/225 g grains, 50 and 80 per cent emergence was observed up to 90 to 100 days and 100 to 110 days, respectively, after infesting the grains.
