“…Resistance to broad-spectrum insecticides in populations of D. citri has been reported in a number of studies from various geographic regions including Pakistan (Naeem et al, 2016), USA (Kanga et al, 2016) and Mexico (Pardo et al, 2018;Vázquez-García et al, 2013). The present study was conducted to determine the toxicity of 10 different insecticides against D. citri collected from citrus groves in Florida.…”

“…However, we found very low to low resistance for imidacloprid and moderate to even high resistance for thiamethoxam. Levels of insecticide resistance to neonicotinoids among D. citri populations have varied from low (RR 10‐20) (Kanga et al., ; Langdon & Rogers, ; Tiwari et al., ); moderate (<25‐fold) (Vázquez‐García et al., ), to high (>4000‐fold) (Bass, Denholm, Williamson, & Nauen, ; Vázquez‐García et al., ), depending on region sampled. This suggests that susceptibility changes among D. citri occur dynamically depending on the selection pressures facing particular populations and should be subject to regular monitoring in areas where D. citri is targeted with insecticides.…”

Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), adults were collected from eight citrus groves across central Florida, and the level of insecticide resistance to ten insecticides was measured using a bottle bioassay. The gene expression of five cytochrome P450 CYP4 (CYP4C67, CYP4DA1, CYP4DB1, CYP4G70 and CYP4C68) and three glutathione S‐transferase (GSTD1, GSTE2 and GSTE1) genes was characterized in seven field populations of D. citri and compared with a laboratory population. Additionally, we reared four neonicotinoid insecticide resistant field populations in the laboratory and observed susceptibility changes without exposure to insecticides over multiple generations. The eight field populations of D. citri adults showed no and very low levels of resistance (RR = 1 and 2–10) to dimethoate, chlorprifos, carbaryl, fenpropathrin, bifenthrin, flupyradifurone and spinetoram. Very low to low resistance was found to imidacloprid and cyantraniliprole (RR = 2–10 and RR = 10–20). Moderate to high resistance was found for thiamethoxam (RR = 20–50 and RR = 50–100). The CYP4G70 and CYP4C68 genes were expressed at a higher level in field populations as compared with the laboratory population. Also the Davenport, Florida field population exhibited higher expression of all target genes compared to the laboratory population. Susceptibility to imidacloprid and thiamethoxam increased by 6.62‐ and 6.42‐fold, respectively, compared to the levels initially observed in the field over six generations of breeding without exposure. These results indicate that insecticide resistance may reverse in the field if insecticide selection pressure is removed from the spray schedule or with use of a rotational scheme with insecticides of different modes of action. Also, the results support use of insecticide resistance survey program combined with effective rotation for integrated insecticide resistance management of D. citri where huanglongbing (HLB) management includes vector suppression with insecticides.

“…However, this hypothesis requires further investigation. Populations of D. citri do appear to become rapidly resistant to insecticides at up to 4,000-fold resistance ratios when modes of action are not rotated (Vázquez-García et al 2013).…”

“…These findings suggested neonicotinoid/insecticide resistance may be becoming an emerging problem in this species in Florida, however, more recent monitoring has revealed, in contrast to other insecticide classes, a slight decrease in resistance to neonicotinoids [90]. Beyond Florida monitoring of D. citri populations collected from lime orchards in Central West Mexico has recently revealed widespread, mostly moderate, resistance (<25-fold) to both imidacloprid and thiamethoxam [91]. However, a strain collected from one site (Apatzingan, Michoacan) displayed extremely high resistance to imidacloprid (>4000-fold) suggesting the emergence of more potent resistance in this area [91].…”

The first neonicotinoid insecticide, imidacloprid, was launched in 1991. Today this class of insecticides comprises at least seven major compounds with a market share of more than 25% of total global insecticide sales. Neonicotinoid insecticides are highly selective agonists of insect nicotinic acetylcholine receptors and provide farmers with invaluable, highly effective tools against some of the world's most destructive crop pests. These include sucking pests such as aphids, whiteflies, and planthoppers, and also some coleopteran, dipteran and lepidopteran species. Although many insect species are still successfully controlled by neonicotinoids, their popularity has imposed a mounting selection pressure for resistance, and in several species resistance has now reached levels that compromise the efficacy of these insecticides. Research to understand the molecular basis of neonicotinoid resistance has revealed both target-site and metabolic mechanisms conferring resistance. For target-site resistance, field-evolved mutations have only been characterized in two aphid species. Metabolic resistance appears much more common, with the enhanced expression of one or more cytochrome P450s frequently reported in resistant strains. Despite the current scale of resistance, neonicotinoids remain a major component of many pest control programmes, and resistance management strategies, based on mode of action rotation, are of crucial importance in preventing resistance becoming more widespread. In this review we summarize the current status of neonicotinoid resistance, the biochemical and molecular mechanisms involved, and the implications for resistance management.
