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 )
