When larvae were infected with C6/36 densovirus (C6/36DNV), the mortality reached 97.46% within 21 days for those larvae infected at the first day after hatching, and 14.17% for control. A real-time quantitative polymerase chain reaction (qPCR) was used to trace the dynamic change of the quantity of C6/36DNV genomes in the larvae and the adults, and to study the interaction of C6/36DNV with dengue virus type II(DEN-II) in mosquitoes. It showed that C6/36DNV could persist in the adults that could transmit C6/36DNV vertically to the next generation. The quantity of C6/36DNV after DEN-II infection increased by 10~10 times in the C6/36DNV-positive mosquitoes, and the quantity of DEN-II in the C6/36DNV-positive mosquitoes was about 100 times lower than that in the C6/36DNV-negative mosquitoes, which suggested that DEN-II could remarkably stimulate the reproduction of C6/36DNV, while C6/36DNV persisted in mosquitoes could inhibit the reproduction of DEN-II. The study throws light on C6/36DNV as a possible biologic control agent against dengue virus and .
