Background The combination of Wolbachia -based incompatible insect technique (IIT) and radiation-based sterile (SIT) can be used for population suppression Aedes aegypti . Our main objective was to evaluate whether open-field mass-releases w AlbB-infected Ae males, as part an Integrated Vector Management (IVM) plan led by the Mexican Ministry Health, could suppress natural populations in urbanized settings south Mexico. Methodology/Principal findings We implemented a controlled...
Background In the absence of vaccines or drugs, insecticides are mainstay Aedes -borne disease control. Their utility is challenged by slow deployment resources, poor community compliance and inadequate household coverage. Novel application methods required. Methodology principal findings A 10% w/w metofluthrin “emanator” that passively disseminates insecticide from an impregnated net was evaluated in a randomized trial 200 houses Mexico. The devices were introduced at rate 1 per room...
Background The integration of house-screening and long-lasting insecticidal nets, known as insecticide-treated screening (ITS), can provide simple, safe, low-tech Aedes aegypti control. Cluster randomised controlled trials in two endemic localities for Ae . south Mexico, showed that ITS conferred both, immediate sustained (~2 yr) impact on indoor-female infestations. Such encouraging results require further validation with studies quantifying more epidemiologically-related endpoints,...
To evaluate the protective effect of house screening (HS) on indoor Aedes aegypti infestation, abundance and arboviral infection in Merida, Mexico.In 2019, we performed a cluster randomised controlled trial (6 control 6 intervention areas: 100 households/area). Intervention clusters received permanently fixed fiberglass HS all windows doors. The study included two cross-sectional entomologic surveys, one baseline (dry season May 2019) post-intervention (PI, rainy between September October...
Abstract A cluster-randomized controlled trial quantified the entomological efficacy of aerial ultra-low volume (AULV) applications insecticide chlorpyrifos against Aedes aegypti in Puerto Vallarta, México, during November–October 2017. The involved 16 large (1 × 1 km) clusters distributed between treatment-control arms. Primary endpoint was abundance Ae. indoors (total adults, females, and blood-fed females) collected using Prokopack aspirators. After four consecutive weekly cycles AULV,...
