Abstract excerpt
BACKGROUND: The cotton bollworm Helicoverpa armigera (Hübner) has developed esterase-mediated resistance to pyrethroids in Central Africa. To gain a better understanding of how quickly this resistance can evolve, its genetic basis and stability were examined in a field-derived strain of H. armigera (474-fold resistant to cypermethrin). RESULTS: Genetic crosses between susceptible, resistant and F(1) hybrids...
