Vertical transmission of dengue 1 virus by Haemagogus equinus mosquitoes.
Vertical transmission of dengue type 1 virus was demonstrated by a strain of Haemagogus equinus mosquitoes from Panama. Parental females were infected by intrathoracic inoculation and egg production was stimulated by feeding on mice. Dengue 1 virus was detected in fourth instar larval progeny obtained from two installment hatches of eggs. Minimum filial infection rates ranged up to 1:495.
