Insecticide rotation scheme restores insecticide susceptibility in thiamethoxam-resistant field populations of Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), in Florida.

Our results revealed that D. citri populations develop a high level of resistance following only three or four consecutive neonicotinoid sprays; this was associated with subsequent product failure. Our data suggest that metabolic detoxification by cytochrome P450s contributes to thiamethoxam resistance in D. citri. Overall, the investigation demonstrated that resistance to thiamethoxam can be managed readily in populations of D. citri by rotating modes of action.
