Bioefficacy of different insecticidal treatments on pupal population of Melanagromyza obtusa (Malloch)

B Chiranjeevi and SV Sarnaik

A field experiment was conducted to explore the bioefficacy of different insecticidal treatments (neem oil @ 3%, pongamia oil @ 3%, eucalyptus oil @ 5%, curry leaf extract @ 5%, custard apple seed extract @ 5%, chlorantraniliprole 18.5 SC @ 30 g a.i. per ha, flubendiamide 480 SC @ 48 g a.i. per ha, emamectin benzoate 5 SG @ 11 g a.i. per ha, triazophos 40 EC @ 500 g a.i. per ha, lambda-cyhalothrin 4.9 CS @ 25 g a.i. per ha and untreated control) on pupal population of Melanagromyza obtusa (Malloch) at Agriculture Research Station, Badnapur during Kharif, 2015-2016. The treatment with chlorantraniliprole 18.5 SC @ 30 g a.i. per ha was found best with minimum pupal population of M. obtusa i.e. 12.00, 9.00, 5.00, 3.33 and 10.00; and 11.00, 5.67, 5.67, 4.67 and 9.33 pupae per 100 pods on one, three, seven, ten and fourteen days after first and second spray and it was followed by neem oil @ 3%. The least effective treatment was Eucalyptus oil @ 5 per cent with maximum pupal population of M. obtusa i.e. 16.00, 21.00, 15.67, 15.67 and 25.33; and 14.33, 13.67, 16.33, 18.00 and 20.00 pupae per 100 pods at one, three, seven, ten and fourteen days after first and second spray. The result revealed that chlorantraniliprole 18.5 SC @ 30 g a.i. per ha was found best treatment with minimum pupal population after the both insecticidal spray.
