Vliv aplikace insekticidů na slunéčko východní (Harmonia axyridis)
Kintlerová, Jarmila
The diploma thesis was focused on evaluating the influence of selected active ingredients of insecticides used to protect agricultural crops on populations of the invasive species of harlequin ladybird (Harmonia axyridis Pallas, 1773) obtained from various locations within the Czech Republic. Four active ingredients, acetamiprid, indoxacarb, lambda-cyhalothrin and tau-fluvalinate, were tested according to the IRAC methodology on populations of adult individuals collected at seven locations. The experiment was done in the form of adult vial test, with subsequent evaluation using the Polo Plus 2.0 software. Based on the obtained results of mortality and lethal doses of active ingredients, it was found that the populations were highly sensitive to acetamiprid and lambda-cyhalothrin and sensitive with possible emergence of resistance to tau-fluvalinate. In the case of indoxacarb, populations from three locations showed moderate to high resistance.
