Overview

Analysis shows varied biological fitness in pink bollworm strains under cry toxin exposure, indicating resistance implications.

Key Points

  • Higher cry toxin concentrations negatively affect biological fitness in pink bollworm, including reduced fecundity and prolonged development.
  • The lowest fitness costs were observed in highly resistant strains at lower toxin levels, with susceptible strains showing the highest mortality rates.
  • Susceptible strains exhibited superior survival rates and development under non-stress conditions compared to resistant strains.
  • Overall fitness costs were strongly associated with larval survival and adult emergence, emphasizing resistance trade-offs.
