Abstract : quantitative genetic variation in larval tolerance to cyhalothrin and fenvalerate was examined in a pyrethroid - resistant population of cotton bollworm, helicoverpa armigera ( h & uuml ; bner ) was examined with half - sibling analysis and significant additive genetic variation in larval tolerance was detected, demonstrating that tolerance phenotypes in this population are highly heritable ( h2n narrow sense heritability = 0. 4625 0. 1578 ) to fenvalerate than that to cyhalothrin ( h2n = 0. 2476 0. 0248 )
