所有4种登革热血清型的经卵传播均在A.白纹蚊这种传播率因病毒的血清型和毒株而异。一般而言，1型登革热病毒株的感染率最高，3型登革热病毒株的感染率最低。尽管使用了4种登革热血清型的病毒株，但A.白纹伊蚊经卵传播。埃及人只感染1型登革热，而且发病率相对较低。五种不同的A.使用了埃及人，包括已知对登革热病毒的口腔感染相对敏感的埃及人。研究结果支持了A.埃及人虽然从登革热向人类传播的角度来看非常重要，但在登革热病毒的整个自然史中可能相对不重要。
Transovarial transmission of all 4 dengue serotypes was demonstrated in A. albopictus mosquitoes. The rates of such transmission varied with the serotype and strain of virus. In general, the highest rates were observed with strains of dengue type 1 and the lowest with dengue type 3. Despite the use of viral strains of the 4 dengue serotypes which gave the highest rates with A. albopictus, transovarial transmission was observed in A. aegypti only with dengue type 1, and then only at a relatively low rate. Five different stains of A. aegypti were employed, including one that was known to be relatively susceptible to oral infection with dengue viruses. The findings support the view that A. aegypti, while of major importance from the point of view of transmission of dengue to man, may be relatively unimportant in the overall natural history of dengue viruses.
