ABSTRACT
Mustard sawfly, A. lugens proxima, was found to be highly susceptible to entomopathogenic nematode, S. feltiae under laboratory condition. Application of three different doses of S. feltiae, viz. 1.1 x 10(3), 1.1 x 10(4) and 1.1 x 10(5) infective juveniles/ml, at weekly intervals, significantly reduced the field population of mustard sawfly on radish. The mean larval population of A. lugens proxima in all doses of nematode treated plots ranged from 0.42 to 0.48 larvae per plant as against 2.95 larvae / plant in untreated control plots. Similarly, the yield of radish in all the nematode treated plots was significantly higher by way of recording 2.80 to 2.87 tons/ha as compared to 1.63 tons/ha in the case of control.
