The present in vitro studies on bio-efficacy of granular, oil based and wettable powder formulations on various sucking pests were carried out at Entomology laboratory, Institute of Organic Farming (IOF), University of Agricultural Sciences, Dharwad. Among different formulations evaluated viz., rice bran oil (60 %) + corn oil (40%) formulation found least LC50 value against corn aphids (0.182 x106 cfu / ml), grape vine mealy bug (0.560 x 106 cfu / ml), cotton thrips (0.591 x 106 cfu / ml), and guava whitefly (0.942 x 106 cfu / ml). The olive oil formulation recorded least LC50 value 0.674 x 106 cfu / ml was against soybean mite. The wettable powder formulation found inferior by recording highest LC50 value against corn aphid (0.261 x108cfu / g), grape vine mealybug (0.740 x 108 cfu / g), cotton thrips (1.019 x 108 cfu / g), guava whitefly (1.757 x 108 cfu / g) and soybean mite (0.917 x 108 cfu / g) at 120 h. Oil formulations are compatible with other integrated pest management approaches. These formulations provide scope for the application of entomopathogens in arid climate where the temperature and relative humidity are major constraints.
