Efficacy of different insecticidal treatments on population of pod fly, Melanagromyza obtusa (Malloch)

B Chiranjeevi and SV Sarnaik

The present study revealed that the treatment application of chorantriniliprole 18.5 SC @ 30 g a.i. per ha was found to be most effective in reducing population of Melanagromyza obtusa (Malloch) on one, three, seven, ten and fourteen days after first and second spray i.e. 46.33, 25.33, 16.67, 14.00 and 28.00; 41.33, 40.00, 17.67, 14.00 and 28.67 pod flies (larvae + pupae) per 100 pods and followed by neem oil @ 3 percent i.e. 50.67, 33.33, 22.67, 18.00 and 24.00; and 43.67, 44.67, 22.00, 17.67 and 31.33 pod flies per 100 pods indicating that these insecticides were more effective in suppressing M. obtusa population (larvae + pupae). Application of Eucalyptus oil @ 5 percent (60.67, 63.67, 54.33, 55.00 and 71.67; and 54.67, 58.33, 54.33, 53.00 and 66.00 pod flies per 100 pods on one, three, seven, ten and fourteen days after first and second spray) resulted as less effective in suppressing the population of pest, M. obtusa. The maximum population of M. obtusa was observed in untreated control i.e. 73.67, 98.67, 111.67, 122.67 and 156.67; and 100.33, 74.33, 131.67, 132.67 and 171.67 pod flies per 100 pods on one, three, seven, ten and fourteen days after first and second spray indicating that application of insecticides is necessary to suppress the M. obtusa population.
