Martins, W. F. S., Reid, E., Tomlinson, S., Evans, G., Gibson, J., Guy, A., Donnelly, M., & Weetman, D. (2023). Improving the efficiency of aerosolized insecticide testing against mosquitoes. Scientific Reports, 13, Article 6281. https://doi.org/10.1038/s41598-023-33460-0
Summary:
This study presents a novel and optimized method to improve the efficiency and reliability of testing aerosolized insecticides on mosquitoes. The research highlights how traditional testing methods may not accurately reflect real-world conditions, potentially leading to misjudgment of product efficacy. By refining exposure protocols, the study offers a more robust approach for evaluating household insecticide effectiveness, which is crucial for public health decision-making in vector control.

Parasites & Vectors, 12, Article 1. https://doi.org/10.1186/s13071-019-3490-z
Summary:
This paper introduces a sensitive and cost-effective PCR-based molecular diagnostic tool for detecting tri-allelic variations in the Vgsc-L1014F gene. These mutations are strongly linked to resistance against pyrethroids and organochlorines in Culex quinquefasciatus. The tool enhances the ability to monitor and track resistance evolution in mosquito populations, supporting better-targeted control interventions.

PLOS Neglected Tropical Diseases, 11(10), e0005917. https://doi.org/10.1371/journal.pntd.0005917
Summary:
The study investigates insecticide resistance patterns in Culex quinquefasciatus across Uganda. Despite high gene flow, resistance profiles were found to be spatially heterogeneous, indicating localized selection pressures. This implies that national-scale control programs may be less effective if local variation is not considered, emphasizing the need for region-specific strategies.
