Abstract
A 110‐fold acetamiprid‐resistant Plutella xylostella (L) strain was established after four selection experiments (in five generations) on a 9.5‐fold resistant colony in the laboratory. The resistant strain did not show cross‐resistance to chlorfluazuron or Bacillus thuringiensis subsp kurstaki Berliner, but displayed low resistance to cartap and phenthoate.
