Little evidence exists to support the efficacy of mosquito abatement programs.

Dengue fever is the most rapidly advancing vector-borne disease in the world. This study aims to systematically review the effectiveness of biological, chemical and educational dengue fever prevention programs on the reduction of entomologic indicators. The Breteau, House and Container Indices were the primary measurement tools for monitoring larval populations. Findings showed 8 studies related to behavioural methods; 8 used biological methods; 8 studies used chemical control techniques with 3 using a combination of intervention techniques. Post-intervention reduction in entomologic indices ranged from 13.9% to 100% increase from baseline. The authors reported weak study designs, incongruent indices and poorly reported statistics.
