However, due to changes in behaviour in NPV infected A. <i>atkinsoni </i>by way of coming out of the pod, there was a significant difference when counts were taken with regard to total number of larvae found feeding inside the pod. Both endosulfan at (0.07%) and virus (125 LE/ha) in combination with endosulfan (0.035%) significantly reduced the larval population of A. <i>atkinsoni </i>and <i>Sphaenarches anisodactylus. </i>There was no significant difference between the virus and control plots with regard to percentage of pod damage. However, when the yield was assessed based on the seed weight, there was significant difference.

Application of three different doses of S. <i>feltiae, </i>viz. 1.1 x 10³, 1.1 × 10⁴ and 1.1 x 10⁵ infective juveniles/ml, at weekly intervals, significantly reduced the field population of mustard sawfly on radish. The mean larval population of A. <i>lugens proxima </i>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.

Higher amylase activity is observed in the initial hours of imbibition in the resistant biotype. In the susceptible biotype it is activated at a much later stage.
