Abstract:

A field experiment on seasonal abundance of rice leaf folder and its natural enemies under irrigated condition was carried out on farmer’s fields in villages (Murchipur, Shivdaspur and Dabhasemar) of District- Faizabad (U.P). The incidence of leaf folder was relatively more in Kharif, 2013 as compared to Kharif, 2014. The maximum population and damage of leaf folder was recorded in village Dabhasemar followed by Shivdaspur. The predators i.e. spiders, coccinellids, ground beetles, earwigs, dragonflies and damselflies were dominant in both Kharif seasons. Highest population of spiders, coccinellids, and the ground beetles per 5 hills and per five sweeps was recorded at 75 to 90 days after transplanting, while the maximum population of earwigs, dragonflies and damselflies were recorded at 60 to 75 days after transplanting. Among parasitoids the Apanteles sp, Itoplectic sp, Xanthopimpla sp and Trichogramma sp were dominating. However, the maximum population of parasitoids was recorded between 75 to 90 days after transplanting.


Keywords: Rice leaf folder, Cnaphalcrocis medinalis, Natural enemies, Coccinellids and Trichogramma spp.
