Efficacy of insecticides against mango leaf webber, Orthaga exvinacea Hampson under laboratory conditions

Abstract

Laboratory studies were conducted to evaluate the efficacy of insecticides against mango leaf webber, Orthaga exvinacea Hampson, at the Post Graduate Research laboratory, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat, India. Six insecticides viz., chlorpyriphos 20 EC, chlorantraniliprole 18.5 SC, chlorfenapyr 10 SC, carbosulfan 25 EC, imidacloprid 17.8 SL, and Azadirachtin 1 EC, were tested against O. exvinacea. Among them, the treatment with chlorantraniliprole 18.5 SC showed the highest mortality against O. exvinacea, followed by the treatments with chlorpyriphos 20 EC and chlorfenapyr 10 SC. Whereas, azadirachtin 1 EC showed the least mortality. Chlorantraniliprole 18.5 SC was the most effective in controlling O. exvinacea, while azadirachtin 1 EC was the least effective.
