Tebufenpyrad (Pyranica (R)) resistance detected in two-spotted spider mite Tetranychus urticae Koch (Acari : Tetranychidae) from apples in Western Australia
Experimental and Applied Acarology 22 (11), 633-641
Abstract: A strain (WA) of Tetranychus urticae Koch was collected from apples in Western Australia following a reported field-control failure of tebufenpyrad. The WA strain had been exposed to five tebufenpyrad applications over four seasons. The tebufenpyrad resistance in the WA strain was confirmed at 63.29× which is the first reported instance of tebufenpyrad resistance in T. urticae. The tebufenpyrad resistance in T. urticae conferred a >210× cross-resistance to pryidaben, a 24.60× cross-resistance to fenpyroximate and a 2.20× cross-resistance to chlorfenapyr.
