Studies were performed on sweet pepper and on weeds in their surroundings from 2005 to 2007 in the Jászság region, on different vegetables and ornamentals from 2015 to 2016 throughout Hungary, and on some indoor ornamental plants in Budapest and Kecskemét in 2017. These studies were carried out in greenhouses. The main objectives of this work was to clarify the consistency of Thysanoptera populations in these greenhouses and, secondly, as part of the official monitoring of Thrips palmi Karny and Thrips setosus Moulton, the study also focused on the first appearance of these pests in Hungary. An important additional aim was to determine which reservoirs were significant in the risk of Thysanoptera species transmitting tomato spotted wilt virus (TSWV). Regarding the surveys conducted, the most frequent Thysanoptera species present in large numbers during the investigation period in every greenhouse was Frankliniella occidentalis Pergande. Also, a significant amount of Echinothrips americanus Morgan was found on ornamentals in southern Hungary, whereas on indoor ornamental plants only Hercinothrips femoralis O. M. Reuter was found.
