Rezistence blýskáčka řepkového (Brassicogethes aeneus, Fabr. 1775) k vybraným účinným látkám insekticidů
 Langová, Melanie
The aim of this thesis was to evaluate the status of resistance of the pollen beetle (Brassicogethes aeneus, Fabr. 1775) to selected active ingredients of insecticides in 2020. The tested active ingredients were lambda-cyhalothrin, tau-fluvalinate, indoxacarb and Biscaya 240 OD (thiacloprid) according to IRAC testing methodology (Insecticide Resistance Action Committee) 011, 021 and 027 (adult vial test). After application of different concentrations of the insecticides were statistically evaluated their percent-age efficacy, degree of resistance of the population and lethal dose by Polo Plus 2.0 software. Based on the results, it was found that Brassicogethes aeneus populations showed resistance to lambda-cyhalothrin and tau-fluvalinate. Individuals were highly sensitive to indoxacarb. Brassicogethes aeneus showed considerable variability in the degrees of resistance against Biscaya 240 OD. Indoxacarb appears momentally to be the best way of plant protection, but further monitoring is important.
