Screen traps as an efficient method in faunal research on fungus-feeding thrips (Tubulifera: Phlaeothripidae)

Studies on fungus-feeding thrips were carried out in two national parks ranked as biosphere reserves: the Białowieża National Park (north-east Poland) and the Bieszczady National Park (south-east Poland). IBL-2 screen traps were used as the main method in the forest communities. Traps were deployed in managed forests and the strict reserve in the Bialowieża NP, and along two trails in the lower forest belt up to its upper border with mountain meadows in the Bieszczady NP. Using IBL-2 traps revealed the presence of ten mycophagous species in the Białowieża NP and six in the Bieszczady NP. In the former Hoplothrips carpathicus, H. fungi, H. unicolor and H. polysticti, and in the latter H. carpathicus and Maderothrips longisetis were recorded for the first time in Poland.
