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.

During the year 2018, the occurrence of pests was monitored in the garden by pheromone traps for Cydia funebrana and Cydia molesta, by yellow spheric traps for Rhagoletis cerasi. For the other species of pests, visual inspection was chosen. The flight period of Cydia funebrana started on 1st May. The flight achieved its maximum during period, which lasted from 27th to 30th June. The last individual was found on 7th September. Totally 114 individuals were caught. The first individual of Cydia molesta was registered on 28th April. The maximum flight was from the 9th to 12th June and the last individual was found on 10th September. Totally 126 individuals were caught. The flight period of Rhagoletis cerasi started on 13th May and maximum was reached from the 10th to 17th June. Totally 87 individuals were caught. On 19th April some species of aphids on different woods were found, Brachycaudus helichrysi, Aphis grossulariae, Cryptomyzus ribis and Aphis pomi.
