“…Only recently, Xu et al 23 demonstrated the functional expression in Xenopus oocytes of five GluCl genes from the carmine spider mite, Tetranychus cinnabarinus, considered as a synonymous species of T. urticae. 24 However, the effect of resistance-associated mutations reported for T. urticae on channel sensitivity to macrocyclic lactones was not investigated. In this study we functionally expressed GluCl3 WT and GluCl3 326E in Xenopus oocytes and describe their sensitivity to L-glutamic acid, abamectin and milbemycin A4.…”

“…Tetranychus cinnabarinus is one of the most damaging polyphagous mites in the world. The species is also referred to as the red morph of Tetranychus urticae , although some studies consider them sibling species . The species is notorious for its ability to feed on a vast array of plant species, such as tomatoes, peppers, cucumbers, strawberries, and major crops, such as soybean and maize .…”

BACKGROUND: Increased expression or point mutations of carboxyl/cholinesterases (CCEs) have been involved in many cases of insecticide and acaricide resistance. However, it has been only rarely documented that downregulation of CCE genes is associated with resistance, although many insecticides and acaricides need hydrolytic activation in vivo. Previously, expression analysis of a laboratory-selected cyflumetofen-resistant strain of Tetranychus cinnabarinus indicated that resistance was associated with increased expression of a CCE gene of TcCCE04, but also the downregulation of two CCE genes, TcCCE12 and TcCCE23.RESULTS: Synergism experiments revealed the importance of ester hydrolysis in cyflumetofen toxicity, because treatment with S,S,S-tributylphosphorotrithioate (DEF) caused strong inhibition of cyflumetofen hydrolysis, in both the susceptible and resistant strains. Moreover, silencing expression of TcCCE12 and TcCCE23 via RNAi further decreased the susceptibility of mites to cyflumetofen significantly, suggesting that downregulated CCE genes could be involved in cyflumetofen resistance. In addition, it was shown that recombinant TcCCE12 protein could hydrolyze cyflumetofen effectively. CONCLUSION: Decreased esterase activity via downregulation of specific CCE genes most likely contributes to cyflumetofen resistance by decreased activation of cyflumetofen to its active metabolite. Mixtures of cyflumetofen and esterase-inhibition acaricides (e.g. organophosphates or carbamates) should be avoided in field applications.

“…Its morphological, biological and molecular characteristics are quite similar to those of the two-spotted mite, Tetranychus urticae. Therefore, some researchers have also considered them as two forms (red and green) of a single species (T. urticae) (de Mendonça et al, 2011;Auger et al, 2013). The use of chemical insecticides and acaricides is currently the main method to control mites.…”

A microRNA‐1 gene, tci‐miR‐1‐3p, is involved in cyflumetofen resistance by targeting a glutathione S‐transferase gene, TCGSTM4, in Tetranychus cinnabarinus

microRNA-1 (miR-1) is a well-studied conservative microRNA (miRNA) involved in immune responses in mammals and insects. However, little is known about its role in pesticide resistance in arthropods. In this study, we found that a microRNA belong to miR-1 family (tci-miR-1-3p) was significantly down-regulated in a cyflumetofen-resistant strain (CYR) of Tetranychus cinnabarinus compared with its homologous susceptible strain (SS), indicating an involvement of miR-1 in cyflumetofen resistance in mites. One glutathione S-transferase (GST) gene (TCGSTM4, a mu class GST gene), a candidate target gene of tci-miR-1-3p, was found to be significantly down-regulated when tci-miR-1-3p was over-expressed. The specific interaction between tci-miR-1-3p and the target sequence in the 3' untranslated region of TCGSTM4 was confirmed. A decrease or increase in tci-miR-1-3p abundance through feeding miRNA inhibitors or mimics significantly increased or decreased TCGSTM4 expressions at the mRNA and protein levels, respectively. In addition, an over-expression of tci-miR-1-3p resulted in a decrease in the tolerance of T. cinnabarinus to cyflumetofen in both SS and CYR strains, and vice versa. After decreasing TCGSTM4 transcription via RNA interference, T. cinnabarinus became more sensitive to cyflumetofen in both resistant and susceptible mites, and the change in mortality was greater in CYR than that in SS. Moreover, the recombinant TCGSTM4 could significantly decompose cyflumetofen, indicating that TCGSTM4 is a functional gene responsible for cyflumetofen resistance in mites.
