How to identify and control the outbreak of sawfly in mustard

This pest causes more damage to the mustard crop after 25-30 days of germination.
The rear part of the female adult of this insect is very developed and saw-like, due to which it lays eggs in the leaves by piercing. It sucks the sap from the plant, along infects the flower and flies away. Often this fly devours the major part of the inflorescence, which stops the growth of the plant.
The larva of this insect feeds on leaves after sunset and in the early morning and remains hidden inside the soil during the day.
When there is more outbreak of sawfly on the crop, instead of the leaves, only the web of veins remains.
To control, take a spray of Profenophos 50% EC @ 500 ml or Thiamethoxam 12.6% + Lambda Cyhalothrin 9.5% ZC @ 80 gm or Emamectin Benzoate 5% SG @ 100 gm/acre.
For biological control, use Bavaria bassiana @ 250 gm/acre.
