Permethrin resistance associated with inherited genes in a near-isogenic line of Musca domestica.

Permethrin resistance in the Perm-R strain of M. domestica was inherited as autosomal, incompletely dominant and governed by more than one gene. Lack of cross-resistance between permethrin and propoxur, chlorpyrifos, profenofos or spinetoram provides an opportunity for rotational use of these insecticides in the control of M. domestica. These data could help to manage M. domestica and the problem of permethrin resistance.
