In India, soyabean pays a significantly to the Indian edible oil pool. It contributes 25% to the total oil production in the country. In recent years consumption of soyabean meal is increasing day by day in India. The productivity of soyabean is mainly hampered by infestation of insects viz. aphids, jassids, white flies and white grubs. White grub is a major pest that is found in various regions of western Maharashtra, India. In nature larvae of white grubs are voracious feed any kind of roots orsubterranean stems. Biopesticides are ecofriendly and effective against the population of grub. Several entomopathogens are disease causing organisms which inevitably infect to white grubs, that kill them or decrease their future generations. Photorhabdus luminescens, a symbiont of Heterorhabditis indica, have insecticidal activity towards insect pests by exerting an array of toxic effects. In the present investigation, efficacy of developed formulation of Photorhabdus bacteria isolated from was Heterorhabditis indica was studied. The field trial was conducted at farmer field with soyabean crop infested by white grubs. The mean population of white grubs recorded before the initiation of application was uniform ranging from 2.66 to 3.08 larvae per plant. After 7 days of treatment with formulation of Photorhabdus, 52.94 % larval population was reduced. The significant reduction in white grub larval population i.e. 83.34 % was noted at 45 days after treatment (DAT) over untreated control
