The Bachelor thesis deals with modern protection methods of coniferous seedlings against the maturation feeding by large pine weevil (Hylobius abietis). Extensive disasters caused by natural disturbances are increasingly attacked by the beetle of this physiological pest. Unsuccessful attempts to afforest these areas by the impact of the pest require considerable financial costs as well as adverse impacts on the landscape. The aim of this work was to verify the biotechnical protection of seedlings by using modern ecological technology - waxing, and then comparing this method with other, whether classical or new ways of protection. The thesis presents the results of current experiments conducted in laboratory as well as in natural conditions. The mortality of the treated seedlings was ordinarily lower than of untreated seedlings. The results of the thesis show a clear efficacy of the protection method of coniferous trees as the most environmentally friendly and cheapest alternative to conventional protection.
