Conclusion
The experimental data discussed above confirm that many insect cell lines are suitable for Baculoviruses, especially for the production of NPV after primary virus infection. However prolonged undiluted passagein vitro may result in virus variation and a decline of virulence for the original host.
This phenomenon is interesting as an example of virus attenuation in the system Baculovirus—in vitro cultured cell. Such phenomena must be taken into account when working with cell cultures in basic laboratory studies of the growth of Baculoviruses. It is also of practical importance, NPV variants unsuitable for insecticide production may be selected. Standard virological techniques can be applied to avoid such selection and to preserve the original characteristics of the virus population.
Further studies of Baculoviridae attenuation and host-virus interactions controlling infective processes are necessary in order to understand the mechanism of attenuation and the factors that influence the evoluation ofBaculoviridae.
