Abstract
Leta 2016 smo na različnih lokacijah v Sloveniji nabrali odrasle osebke repičarja (Meligethes aeneus). V laboratoriju smo nato preučevali njihovo odpornost proti štirim različnim piretroidom; alfa-cipermetrin, deltametrin, lambda-cihalotrin in beta-ciflutrin v različnih odmerkih (25, 50, 100, 200, 400 in 800 % priporočenega odmerka). Namen raziskave je bil ugotoviti odpornost repičarja proti omenjenim piretroidom. Vsako obravnavanje je imelo tri ponovitve. Pri rezultatih poskusa smo ugotovili, da piretroidi različno učinkujejo na populacijo osebkov repičarja. Na prvi lokaciji je bil največji učinek pri piretroidu Decis 2,5 EC (deltametrin) pri 800 % odmerku, najmanjši pa pri piretroidu Bulldock EC 25 (beta-ciflutrin) pri 25 % odmerku. Na drugi lokaciji se je najbolje obnesel pripravek Karate Zeon 5 CS (lambda-cihalotrin) pri 200 % odmerku, najslabše pa pripravek Karate Zeon 5 CS (lambda-cihalotrin) pri 25 % odmerku. Pri zadnji lokaciji je bil najbolj učinkovit Decis 2,5 EC (deltametrin) pri 100 % odmerku, najmanj pa Fastac 100 EC (alfa-cipermetrin) pri 50 % odmerku.

Title:The laboratory investigation of Pollen beetle (Meligethes aeneus F., Coleoptera, Nitidulidae) resistance to pyrethroids
Abstract:
The experiment was performed in the year 2016. We were collecting the adults of pollen beetle in different locations in Slovenia. In the laboratory we were investigating the resistance of a pollen beetle with four different pyrethroids: alfa-cypermethrin, deltamethrin, lambda-cyhalothrin in beta-cyfluthrin in six different concentrations (25 %, 50 %, 100 %, 200 %, 400 % and 800 %). The purpose of the study was to determine the resistance of pollen beetle to pyrethroids. We expressed results as percentage affected. Each treatment had three replicates. We found out that pyrethroids have different effects on the different populations of pollen beetles. At the first location the greatest effect was with 800 % deltamethrin and the lowest effect was with 25 % beta-cyfluthrin. On the second location 200 % lambda-cyhalothrin has proved itself with good results, but also the biggest resistance was detected at treating with 25 % lambda-cyhalothrin. At the last location the most effective was 100 % deltamethrin. The less affected were pollen beetles treated with 50 % alfa-cypermethrin.

Keywords:Meligethes aeneus, pollen beetle, resistance, pyrethroids, insecticides, alfa-cypermethrin, deltamethrin, lambda-cyhalothrin, beta-cyfluthrin
