Expression of cytochrome P450 monooxygenase genes in pyrethroid-resistant Aedes albopictus.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Control of dengue vectors with synthetic pyrethroids is employed worldwide but development of pyrethroid resistance in Aedes mosquitoes is a big challenge for successful prevention of dengue. Pyrethroids are of two types: type I (devoid of α-cyano group) and type II (contain α-cyano group) which differ in their toxic effect. Therefore, this study investigated potential difference in the cytochrome P450 monooxygenase (CYP) mediated resistance status against two types of synthetic pyrethroids in wild Aedes (Ae.) albopictus populations from dengue endemic sub-Himalayan West Bengal. The role of CYPs in resistance development was studied through synergist assay and gene expression studies. Widespread resistance was observed against permethrin (type I) and lambdacyhalothrin (type II) in studied populations. Use of Piperonyl Butoxide (PBO) in synergist assay restored susceptibility to both the insecticides and confirmed involvement of CYP in observed resistance. Differential overexpression of three CYP genes, CYP6P12, CYP6A8 and CYP6N3 was observed in all populations and population specific differential induction of CYP6P12 and CYP6A8 upon permethrin and lambdacyhalothrin exposure was also noted. These findings indicate occurrence of monooxygenase mediated pyrethroid resistance in Ae. albopictus populations from this region. Use of monooxygenase blockers can improve the efficacy of pyrethroids for control of this vector.
