Widespread resistance of pollen beetles to pyrethroids in Czechia with no evidence for kdr mutation

Popis výsledku v původním jazyce

The pollen beetle Brassicogethes aeneus (Fabricius, 1775) (Coleoptera: Nitidulidae) is one of the most important pests in oilseed rape (Brassica napus L. var. oleifera Moench) in Czechia. Wide-spread resistance development to pyrethroids in pollen beetle populations was documented in many European countries, including Czechia. The susceptibilities of 10 local pollen beetle populations originating from 10 localities in Czechia to lambda-cyhalothrin, tau-fluvalinate, thiacloprid, indoxacarb and chlorpyrifos were evaluated in 2017?2020 using glass vial bioassays. A high level of resistance to lambda-cyhalothrin was recorded in all the evaluated populations of the pollen beetle. The proportion of the populations resistant to tau-fluvalinate varied between years from 30% to 60%, and in 2018 and 2020, all the tested populations were classified as resistant. Despite the high level of resistance to pyrethroids, a kdr mutation known to cause resistance in the pollen beetle was not detected in any of the 244 tested individuals. In 2017?2020, the first local populations of the pollen beetle with decreased susceptibility to thiacloprid occurred. The LD90 of thiacloprid exceeded the field application dose in 100% and 90% of populations in 2018 and 2020, respectively. All the tested populations were susceptible to indoxacarb and chlorpyrifos. Cross-resistance between lambda-cyhalothrin and thiacloprid and between tau-fluvalinate and thiacloprid was found using data from 2017 to 2020. No cross-resistance between lambda-cyhalothrin and taufluvalinate was detected.
