Abstract: Pollen beetle (Meligethes aeneus F.) is a damaging pest of oilseed rape. Its harmful activity directly threatens the production and in some years it could compromise the yield. In many cases, the products applied in pest control, turn to be less efficient due to the conditions under which they are applied and the restricted application regime. In order to avoid the development of resistance, it is necessary to use insecticides having different mechanisms of action, which continue for a long enough period of time, with the aim of limiting the application of chemical substances and protecting natural pollinators and bees.
