“…Studies of other thrips species (i.e. Frankliniella occidentalis , Thrips palmi ) have previously documented elevated mixed‐function oxidase and carboxylesterase activity in neonicotinoid resistant thrips strains; these results support the hypothesis that detoxification could be one plausible mechanism conferring neonicotinoid resistance in F. fusca.…”

This study shows that insecticides have different effects on F. fusca oviposition events, larval and adult mortality that are dependent on neonicotinoid resistance status. Because insecticides tested in this study have varied activity on specific F. fusca life stages (e.g. oviposition suppression, larvicidal activity, adulticidal activity), knowledge of stage-specific activity can be used to improve control and enhance long-term product stewardship. © 2017 Society of Chemical Industry.

“…Synergism bioassays using the metabolic enzyme inhibitor piperonyl butoxide (PBO) suggested that metabolism by P450s may be involved in acetamiprid resistance in these strains, and cloning and sequencing of nicotinic acetylcholine receptor (nAChR) subunits provided no evidence of a target-site mechanism [99]. Finally, modest levels of resistance to thiamethoxam (15-fold) were also recently reported in a strain of F. occidentalis selected in the laboratory with this compound for 55 generations [100].…”

“…This finding might be explained by a metabolic resistance mechanism that exhibits substrate preference for chlorothiazolylmethyl neonicotinoids such as thiamethoxam and imidaclothiz. In this regard thiamethoxam efficacy against the resistant strains was synergized by PBO and triphenyl phosphate (TPP) and biochemical assays showed modest increased in monooxygenase and carboxylesterase activity suggesting a possible involvement of these enzyme systems in resistance [100].…”

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.

“…Insecticide resistance is a worldwide problem which hinders the success of insect pest control programs. Few reports on thiamethoxam resistance and cross-resistance to other neonicotinoids have been reported in Bemisia tabaci (Gennadius) [ 6 ], Frankliniella occidentalis (Pergande) [ 7 ], M . domestica [ 4 ] and Leptinotarsa decemlineata (Say) [ 8 ].…”

Thiamethoxam Resistance in the House Fly, Musca domestica L.: Current Status, Resistance Selection, Cross-Resistance Potential and Possible Biochemical Mechanisms

et al. 2015

The house fly, Musca domestica L., is an important ectoparasite with the ability to develop resistance to insecticides used for their control. Thiamethoxam, a neonicotinoid, is a relatively new insecticide and effectively used against house flies with a few reports of resistance around the globe. To understand the status of resistance to thiamethoxam, eight adult house fly strains were evaluated under laboratory conditions. In addition, to assess the risks of resistance development, cross-resistance potential and possible biochemical mechanisms, a field strain of house flies was selected with thiamethoxam in the laboratory. The results revealed that the field strains showed varying level of resistance to thiamethoxam with resistance ratios (RR) at LC50 ranged from 7.66-20.13 folds. Continuous selection of the field strain (Thia-SEL) for five generations increased the RR from initial 7.66 fold to 33.59 fold. However, resistance declined significantly when the Thia-SEL strain reared for the next five generations without exposure to thiamethoxam. Compared to the laboratory susceptible reference strain (Lab-susceptible), the Thia-SEL strain showed cross-resistance to imidacloprid. Synergism tests revealed that S,S,S-tributylphosphorotrithioate (DEF) and piperonyl butoxide (PBO) produced synergism of thiamethoxam effects in the Thia-SEL strain (2.94 and 5.00 fold, respectively). In addition, biochemical analyses revealed that the activities of carboxylesterase (CarE) and mixed function oxidase (MFO) in the Thia-SEL strain were significantly higher than the Lab-susceptible strain. It seems that metabolic detoxification by CarE and MFO was a major mechanism for thiamethoxam resistance in the Thia-SEL strain of house flies. The results could be helpful in the future to develop an improved control strategy against house flies.
