DOI: 10.1002/ps.6991
Abstract: BACKGROUND Insect cytochrome P450 monooxygenases (P450s) play a crucial role in phytochemical metabolism and tolerance. Three P450 genes (TcCYP4Q3, TcCYP4Q5, TcCYP4Q7) are associated with the response of eugenol in Tribolium castaneum. However, the responding mechanisms… read more here.

DOI: 10.1016/j.cropro.2021.105687
Abstract: Abstract The detoxification mediated by cytochrome P450 is always involved in insecticide resistance. Our previous studies have demonstrated that multiple P450 genes were overexpressed in the imidacloprid-resistant strain (SA-R) in Sitobion miscanthi. However, the characterization… read more here.

DOI: 10.1016/j.pestbp.2021.104772
Abstract: Metabolic resistance driven by multiple P450 genes is worsening insecticide resistance in malaria vectors. However, it remains unclear whether such multiple over-expression imposes an additive fitness cost in the vectors. Here, we showed that two… read more here.
