Abstract

Transovarial transmission is an important role of Aedes aegypti as an intermediate host. This role is one of the factors dengue virus can survive in nature during interepidemic. DENV-2 transovarial transmission is an important problem because there has been evidence of horizontal transmission of DENV-2 serotypes by vertically infected mosquitoes. The study aimed to determine the mortality rate and gonotropic cycle of serotype denv-2 transovarial transmission through intratoracal in Aedes aegypti mosquitoes. The research method used a quasi-experimental design with the intervention of intratoracal DENV-2 serotype virus infection. The population in this study was Aedes aegypti mosquito female laboratory colony. The results showed a mortality rate of 87.2%, there were differences in the number of gonotropic cycle eggs (p <0.0001) with mean different: 13.5. and infection rate of DENV-2 transovarial transmission is 30-40%. An active role for the community is needed in eradicating mosquito breeding places in each gonotropic cycle.
