Negative cross-resistance between dihydropyrazole insecticides and pyrethroids in houseflies, Musca domestica.
A series of insecticidal dihydropyrazoles and related compounds have been shown to exhibit negative cross-resistance to a resistant (super-kdr) strain of houseflies with site-insensitivity to pyrethroids. The level of cross-resistance is similar to that observed previously for a range of N-alkylamides against the same strain.
