[Demonstration of the remote effect of baculovirus vertical transmission, with gypsy moth Lymantria dispar L. (Lepidoptera, Lymantriidae) as an example].

It is demonstrated for the first time that viral infection can be formed in insects survived after infection of gypsy moth larvae by nucleopolyhedrovirus (NPV), and cause subsequent mortality of individuals during, at minimum, two generations (the period of observations). The vertical virus transmission is carried by both male and female insects survived after infection. It is shown by means of PCR that the level of virus carrying in gypsy moth embryos of generations F1 and F2 is higher than the number of insects killed by NPV.
