Laboratory experiment was conducted on the “Combined efficacy of entomopathogenes and insecticides against white grub, Leucopholis lepidophora (Blanchard) infesting sugarcane in vitro” during 2016-2017 in the Agricultural Entomology Section, College of Agriculture, Kolhapur. In laboratory bioassay studies the entomopathogens like, Heterorhabditis indica, Metarrhizium anisopliae and chemical insecticide Imidacloprid individually and different combinations were tested for their combine efficacy against third instar grubs of L. lepidophora (Blanchard). The treatment M. anisopliae + H. indica + Imidacloprid @ 75 gm + 75 gm + 8 ml was found most effective in controlling the white grub, L. lepidophora. The treatment of M.anisopliae + H. indica + Imidacloprid @ 75 gm + 75 gm + 8 ml recorded 73.33, 82.66 and 87.33 percent grub mortality at 7, 10 and 15 DAT respectively where untreated control recorded 13.00, 16.66 and 20.00 percent grub mortality respectively. The treatment with Imidacloprid, M. anisopliae + Imidacloprid and H. indica + M. anisopliae was found next in order of efficacy.
