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.

Yeast-encapsulated essential oils: a new perspective as an environmentally friendly larvicide.

Background: Effective mosquito control approaches incorporate both adult and larval stages. For the latter, physical, biological, and chemical control have been used with varying results. Successful control of larvae has been demonstrated using larvicides including insect growth regulators, e.
