Lessons learned exploiting a multi-year large-scale data set derived from operational quality assessment of mosquito larval treatments in rain catch basins

Abstract

Larval control is crucial for managing mosquito arbovirus vectors. Quality control (QC) data from insecticide-based interventions are rarely exploited to assess the effectiveness of biocides in the field. This study aims to: (i) evaluate the outcomes of large-scale catch basin treatments with diflubenzuron (DFB) and Bacillus thuringiensis var. israelensis and B. (Lysinibacillus) sphaericus (Bti + Bs) on immature stages of Aedes albopictus and Culex pipiens, with reference to critical variables, such as the intervals between catch basin treatments and inspections; and (ii) identify areas of repeated treatment failures.
