Abstract

Two alternative technologies were evaluated for Aedes aegypti control: the spraying of a biological larvicide (Bti) in potential peridomiciliary breeding sites and the release of sterile males to promote reproduction blockage in wild females. Actions were carried out by Agents of the Health Services, in 15 villages of the Fernando de Noronha Island and in 900 properties from the district of Várzea, Recife-PE. The effectiveness of both methods was evaluated by entomological indicators, estimated by the presence, quantity and viability of eggs from the mosquito collected in traps and through genetic markers. Bti was delivered by backpack sprayer every 30 days in both areas. A significant and sustainable reduction of the A. aegypti population as a result of this technique was achieved in 2015/2016 in Várzea and in 2016 in the Island, where it was strengthened by the removal of 18 tons of solid waste in 2015. Males sterilized with gamma radiation were mass-produced in the laboratory
and released in one village of the Island. The spatiotemporal analysis of the indicators, from Dec/2015 to Aug/2016, revealed a significant reduction in mosquito density, which impacted on the genetic diversity of the local population. Both approaches seem to have reduced human-vector contact and the risk of arbovirus transmission in the Island, although local mosquito population presented high vector competence to Zika and Dengue virus. These methods were efficient and could be integrated into SUS actions directed to A. aegypti control.
