Ovitraps Provide a Reliable Estimate of Frequency during MelBr Strain Deployment in a Geographically Isolated Population.

Deployment of Aedes aegypti mosquitoes carrying the endosymbiont bacterium has been identified as a promising strategy to reduce dengue, chikungunya, and Zika transmission. We investigated whether sampling larvae from ovitraps can provide reliable estimates on frequency during releases, as compared to the expensive adult-based BG-Sentinel. We conducted pilot releases in a semi-field system (SFS) divided into six cages of 21 m, each with five ovitraps.
