Investigations were carried out on “Comparative efficacy of different insecticides against fruit fly, Bectrocera cucurbitae (Coquillet) on cucumber” at Instructional farm, College of Agriculture, Junagadh Agricultural University, Junagadh during kharif-2015 on cucumber variety Dharwad green. The results of the two spraying of Fipronil, Dichlorvos, Polytrin C, Profenophos, Spinosad, Lambda-cyhalothrin, Malathion, Clorantraniliprole and Bifenthrin insecticides against the cucumber fruit fly revealed that Dichlorovos @ 0.05 percent, Lambda-cyhalothrin 0.005 percent and Malathion @ 0.1 percent were found more effective treatments against the pest as compared to other insecticides. Among different treatments the highest ICBR i.e. 1: 62.21 was recorded in the treatment of Dichlorovos @ 0.05 percent followed by Lambda-cyhalothrin 0.005 percent (1: 31.65), Malathion @ 0.1 percent (1: 32.30), Profenophos @ 0.05 percent (1: 15.23) and Bifenthrin 0.005 percent (1: 13.08)
