[Classical fowl plague virus reproduction in the body of Aedes aegypti mosquitoes]. / Reproduktsiia virusa istinnoi chumy ptits v organizme komarov Aedes aegypti.

The results of the studies on fowl plague virus (FPV, Rostok strain) reproduction in Aedes aegypti mosquitoes are presented. The virus-containing allantoic fluid was inoculated intrathoracally in volumes of 0.1 and 0.2 microliter.
