The influence of pyrethroid cypermethrin on non-target species Harmonia axyridis ladybird
Original language description
This study deals with the influence of insecticide active ingredients on selected non-target organisms. Aphidophagous harlequin ladybird (Harmonia axyridis) was the tested species, a non-native species that occurs in large populations across the Czech Republic, even in agrocenosis. The objective was to find out if this useful insect was affected by plant protection products (PPP), as was the case with pests of agricultural crops, and whether the development of resistance against selected active ingredients (AI) of insecticides occurred here as well. During the 2020 vegetation season, individual harlequin ladybirds were collected at selected sites and subsequently tested in a laboratory for sensitivity to cypermethrin AI in different concentrations. The efficiency of this AI was evaluated, and from the values acquired, the percentage mortality at the registered dose was calculated. Results were further processed using the specialised POLO PLUS 2.0 software, which calculates values of lethal doses of LD50, LD90 and LD95. As the results show, the mortality increase was recorded due to the increasing dose of the tested AI. From the calculated mortality values and lethal dose, it was found that harlequin ladybird populations are sensitive to the affect of cypermethrin, and thus, the negative influence of this PPP on non-target organisms was verified.
