Effect of dengue vector control interventions on entomological parameters in developing countries: a systematic review and meta-analysis
Dengue vector control is effective in reducing vector populations, particularly when interventions use a tailored community-based, integrated approach and combined with educational programmes.
Dengue is an emerging arboviral disease mainly transmitted by Aedes aegypti and Aedes albopictus, both mosquito species show breeding preferences for domestic water containers. The aim of this review was to compare the effects of different dengue vector control interventions (biological, chemical, environmental and integrated approaches) with respect to entomological parameters. The systematic review and meta-analysis included 56 publications. Integrated vector management was found to be the most effective method. Environmental management showed a relatively low effectiveness. Biological control usually targeted a small number of people whereas integrated vector management focused on larger populations. New research should assess the density-dependent effectiveness of each control measure in order to estimate whether reducing vector numbers has an impact on dengue transmission when populations are at a critical threshold. Heterogeneity and bias assessments were reported by the authors.
