Impact of vertically-transmitted dengue virus on viability of eggs of virus-inoculated Aedes aegypti.
Autor(es): Joshi, Vinod; Sharma, R. C.
Resumo: Transovarial transmission (TOT) is known to occur in Aedes aegypti. This relationship carries tremendous epidemiological significance. The progeny of virus-inoculated Aedes aegypti were followed for seven generations to observe the impact of the virus on the viability of eggs and their rearing up to the adult stage. Dengue virus was found to exert an adverse effect on the viability of the eggs of the vertically-infected female mosquitoes and their larval and pupal stages upto adults when compared with the control population. While TOT ranged from 15.5% to 67.5% of the total mosquito populations in seven experimental generations, the corresponding adverse effect of the virus on eggs failing to hatch and grow into adults ranged from 30.0% to 68.1%.
