Biochemical mechanisms conferring cross-resistance between tebufenozide and abamectin in Plutella xylostella

Experiments have been carried out to confirm the cross-resistance between abamectin and tebufenozide in Plutella xylostella and demonstrate its mechanism. The results showed that the resistant strain of P. xylostella selected by tebufenozide (RF 99.38) really showed high cross-resistance to abamectin (RF 29.25). When this strain was subjected to resistance decaying treatment, breeding without contacting any insecticides, and abamectin resistance...
