This thesis deals with rape and the possibilities of its protection against pests. The most important pests of this crop include rape stem weevil (Ceutorhynchus napi, Gyllenhal 1837), rape beetle (Brassicogethes aeneus Fabricius, 1775 Meligethes aeneus) and brassica pod midge (Dasineura napi, Loew 1850). In the practical part of the dissertation, 26 variants of application sequences of insecticides were evaluated. The first and last variant was taken as a control and therefore not treated with any insecticide. Insecticides were applied on the basis of pest control. In each variant, an insecticide was first applied, which was primarily intended for rape stem weevil (Ceutonhynchus napi, Gyllenhal 1837). The second insecticide was focused on rape beetles (Brassicogethes aeneus Fabricius, 1775, Meligethes aeneus). The third application of the insecticide was determined for the brassica pod midge (Dasineura napi Loew, 1850). The results were evaluated and entered into tables and subsequently statistically processed using Statistica 12. The aim of this work was to evaluate the most effective sequence of three insecticides against the main rapeseed pests. The view was also taken on an anti-resilient strategy in which insecticides having the same active substance should not be applied.
