Vector and Environmental Control

Rising insecticide resistance is reducing the effectiveness of chemical vector control. Vector control was the most commonly implemented dengue management strategy in the reviewed studies. Countries used physical, chemical, biological, and environmental methods for vector control. Physical vector control included stagnant-water elimination, Gravitraps, and house-to-house inspections. Chemical vector control included ultra-low volume fogging and larvicides in several countries. Wolbachia-infected and genetically modified mosquitoes were increasingly adopted as biological control approaches.
