The development of bifenthrin resistance in two-spotted spider mite (Acari: Tetranychidae) from Australian cotton
Experimental and Applied Acarology 25 (4), 301-310
Abstract: Bifenthrin (Talstar®) was registered at the beginning of the 1993/94 season for control of Helicoverpa spp. and Tetranychus urticae in Australian cotton. Resistance was monitored in T. urticae following registration but despite the implementation of resistance management, resistance evolved in the 1996/97 cotton-growing season after only four seasons use. During the following three seasons resistance increased progressively both in level (from 1.2- to 109-fold at LC_50) and abundance (from 20 to 90% strains) and was linked to field control failures. The evolution of resistance has now reduced the reliability of bifenthrin for T. urticae control in Australian cotton. The impact of bifenthrin resistance in T. urticae and its continued management in Australian cotton is discussed.
