The cytochrome P450 monooxygenases play a key role in detoxification mechanism for spirotetramat resistance in Aphis gossypii Glover. However, only one P450 genes (CYP6DA2), among thirty-five P450 genes identified from Aphis gossypii transcriptome database, has been reported to play important role in spirotetramat resistance in previous resistance...
A thiamethoxam-resistant strain of cotton aphid (ThR) displayed a 13.79-fold greater resistance to thiamethoxam than a susceptible cotton aphid (SS) strain. Piperonyl butoxide (PBO) and triphenyl phosphate (TPP) synergistically increased the toxicity of thiamethoxam in the resistant strain, whereas diethyl maleate (DEM) did not exhibit significant...
Acetyl-coenzyme A carboxylase (acetyl-CoA carboxylase, ACC) catalyses the carboxylation of acetyl-CoA to produce malonyl-CoA during de novo fatty acid synthesis. A laboratory-selected spirotetramat-resistant strain (SR) of cotton aphid was used in this study. RT-qPCR results demonstrated significant increases in the levels of ACC transcript in the...

... Eighty apterous adult aphids were treated with dsRNA as previously described. 27 Enhanced cyan fluorescent protein (ECFP) dsRNA, as a control, was synthesized using the same method after 48 h of treatment. Cyantraniliprole (final concentration: 5 mg/L) and dsRNA-CYP6CY22 (final concentration: 150 ng/μL) were used as artificial diets for rearing to perform mortality experiments using another 80 adult aphids of the CyR strain, and mortality was recorded after 48 h. ...

... Cross-resistance which occurs when insects develop resistance to several active ingredients that have a similar mode of action is a pervasive driver of tolerance to neonicotinoids in agricultural pests [17][18][19][20]. Importantly, significant research has demonstrated that detoxification enzymes, primarily cytochrome monooxygenases (CYPs), play a key role in the development of neonicotinoid resistance in insect pests [21][22][23][24][25]. Due to chronic exposure to public health and agricultural pesticides and other xenobiotic compounds, anopheline populations from sub-Saharan Africa have evolved an impressive array of detoxification mechanisms including overexpression and duplication of CYPs [26][27][28][29][30]. ...
... Interestingly, a reduction in CYP6CY3 levels resulted in a significant increase in the homologous CYP6CY4 gene, implying a potential compensatory relationship between the two [55]. To decipher the posttranscriptional regulation mechanism of the ACC gene (acetyl-CoA carboxylase) in Aphis gossypii, a prediction using its 66 known miRNAs identified miR-276 and miR-3016 as potential ACC regulators, with their abundance showing inverse correlations with ACC transcript levels [56]. Ma et al. (2019) [57] unveiled the regulatory role of miR-4133-3p in the post-transcriptional expression of CYP4CJ1. ...

... In A. gossypii, the composition of symbiotic bacteria undergoes significant changes after insecticide treatment [61]. Notably, antibiotic treatment has also been found to increase the sensitivity of A. gossypii to spirochetes [62]. However, the interaction between aphids and symbionts is intricate. ...
