Evaluation of Indigenous Entomopathogenic Nematodes from Tea Soil of Assam as Potential Biocontrol Agents against Termite and Cockchafer Grub in Tea

This study aimed to isolate native entomopathogenic nematodes (EPN) in the tea growing areas of Assam and determine their potential for control Termite Cockchafer grub Soil samples were collected from three estates jorhat, EPN isolation.A total 30 soil tested study. Larva meal moth, Corcyra cephalonica was use as insect bait. Out 9 found be positive EPNs. The infected host larvae separated extraction using “white trap method”. All isolates evaluated ascertain pathogenicity against cockchafer grub. From experiment isolated strain @ 50IJ, 75IJ 100 IJ highly pathogenic grub, which recorded 94- 100% mortality termite all concentrations After infection prove cause could recovered cadavers.
