Pink Bollworm

  • Cotton farmers in North India may shift to paddy, maize, and guar due to severe PBW infestation.

 

  • About PBW (Pectinophora gossypiella)
    • The disease is common in cotton crops.
    • PBW larvae burrow into developing fruits (bolls) of cotton plants, and damage affects both the weight and quality of harvested bolls.
    • Issue: 
      • Pink bollworms have developed resistance to genetically modified pest-resistant Bt cotton over time.

 

  • Management Strategies
    • Adoption of highly productive short-duration hybrids that would escape PBW.
    • Crop rotation to break the lifecycle of PBW.
    • PB Knot technology disrupts the mating prospects of pests.
