title: Transovarial transmission of Gamboa virus in a tropical mosquito, Aedeomyia squamipennis.
abstract: We report transovarial transmission of Gamboa virus (Bunyavirus) in Aedeomyia squamipennis, a tropical mosquito which is active and bloodfeeding throughout the year. Gamboa virus was isolated during each of the 28 months of the study from every mosquito stage, including eggs, demonstrating that vertical transmission is a maintenance mechanism of this virus. The overall minimum infection rate was 5.1/1,000 mosquitoes. Identification of the 567 isolates by neutralization indicated that greater than or equal to 2 serotypes or subtypes of Gamboa virus circulate at the study site.
