dc.description.abstractExperiments were conducted on effect of various host crops on development and fecundity oi Mythimna separata Walker under laboratory as well as net house conditions, field activity of larval parasite, Apanteles ruficrus Haliday on M. separata infesting maize, sorghimi, bajra and wheat crops, oviposition deterrent and antifeedant properties of some solvent extracted plant materials against M. separata, comparative studies on ovicidal and larvicidal effect of recommended synthetic insecticides against M. separata reared on different hosts in the laboratory of Department of Entomology, Bansilal Amrutlal College of Agriculture, Gujarat Agricultural University, Anand Campus, Anand and field studies to evaluate the resistant variety against M. separata at Forage Research Farm, Gujarat Agricultural University, Anand Campus, Anand during 1998 to 2001. The developmental period of larval, pupal, adult stage as well as total life span remained shorter on maize than bajra and wheat. The longer oviposition and post oviposition period alongwith higher fecundity, egg hatching and larval survival was found on maize. The activity of larval parasite, A. ruficrus during kharif was started from I week of August on M. separata and remained for longer period in maize field, whereas during rabi, it was started from II week of December, The extent of parasitism was higher on sorghum. The activity of A. ruficrus was found to be influenced by abiotic factors. Neem seed kernel extract with methanol (NSKEM) 1% had higher oviposition deterrent property, whereas neem leaves extract with benzene (NLEH) 1% proved superior in their antifeedant property against M. separata. Chlorpyriphos 0.04% proved superior in it's ovicidal and larvicidal property against M. separata followed by quinalphos 0.05% and monocrotophos 0.04%. Among the different sorghum varieties, sorghum C-10-2 was found comparatively with higher resistance against M. separata.en_US
