The fast improvement of cyberattacks in the area of the Internet of Things (IoT) presents novel safety challenges to zero-day attacks. Intrusion detection systems (IDS) are generally focused on exact attacks to defend the use of IoT. However, the attacks were unidentified, for IDS still signifies tasks and concerns about consumers' data privacy and safety.

In the research reported here we studied whether or not phenoloxidase (PO), a key enzyme in the melanogenesis component of humoral immunity of insects, plays a role in the protection of Lymantria dispar larvae from infection by L. dispar multiple nucleopolyhedrovirus.

According to censuring data, the gypsy moth populations of Western Siberia were at the depression stage. The NPV DNA detection frequencies in eggs (8.

We measured larval developmental time, pupal weight, rate of survival to the adult stage, and five characteristics of larval immune defense: (1) encapsulation response; (2) phenoloxidase activity; (3) hemocyte concentration and (4) lysozyme-like activity in the hemolymph; and (5) resistance to infection by L. dispar nucleopolyhedrovirus (LdMNPV).

It was shown that the flavonol content in the leaves did not change after strong and total defoliation, while the amount of tannins did not change during the first 15 days but increased later on 1 and 2 years after 75% and 100% defoliation. The catechine content did not change during the first 15 days and increased later on 1 year after strong and total defoliation; however, it returned to the level of control plants 2 years after both types of defoliations.

The insects feeding on birch leaves had the lowest sensitivity to NPV than those on willow leaves, but the insects growing on pine needles showed the highest susceptibility.

The counts of granulocytes and prohemocytes are increased, as are the counts of hemocytes possessing phenol oxidase activity and hemocytes reducing nitroblue tetrazolium. Atypical virus morphogenesis is observed.
