The bio efficacy of selected bio control agents viz. Metarhizium anisopliae, Beauveria bassiana, Lecanicilium lecanii and Chrysoperla zastrowii against Amrasca biguttula biguttula was studied under insectary, Department of Agricultural Entomology, TNAU, Coimbatore, India during 2014-2015. Three different concentrations viz., 1 x 104 , 1 x 106 , 1 x 108 spore/ml of these each entomopathogenic fungus were tested to evaluate the effective concentration. Among the three concentrations, 1 x 108 spores/ml of L. lecanii recorded the highest mortality of 85.

Studies were carried out for rapid micropropagation of two sugarcane genotypes Co-86032 and CoVC-18061. The explants were surface sterilized with 75% alcohol for 30 minutes using cotton. The cultures were initiated by inoculating shoot apical meristem on MS (Murashige and Skoog, 1962) medium containing 1.0 mg/l kinetin. The multiplication response of two sugarcane genotypes was studied under five levels of 6-Benzylaminopurine (0, 0.5, 1, 1.5 and 2 mg/l) and five levels of kinetin (0, 0.25, 0.5, 1.0 and 1.5 mg/l) in completely randomized design with 5x5x2 factorial treatment combinations.

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.
