Agriculture experts have advised farmers to remove cotton sticks from fields before Jan 31 and apply Chisel plough so that pink bollworms undergoing diapause and their Pupae get killed.
Pink bollworm Pupae undergo diapause in winter season and convert into adult only when temperature touches or crosses 25 Celsius mark. Joint teams of agriculture extension and pest warning were moving from village to village to inform farmers about the hazards related to pink bollworm.
Pink bollworm is a dangerous pest, which after completion of cotton picking, survives on cotton crop remains to complete life cycle۔ Pest warning wing of the agriculture department was also installing pheromone traps at heaps of cotton sticks, at ginning factories and oil mills to monitor pink bollworm. Sticks carry pink bollworm undergoing diapause and thus be destroyed before Jan 31.
