Abstract

The paper presents characteristic and morphological diagnostic features of females and second larval instar of six terebrantian species: Oxythrips ajugae Uzel 1895, O. bicolor (O. M. Reuter 1879), Taeniothrips inconsequens (Uzel 1895), Thrips calcaratus Uzel 1895, T. minutissimus Linnaeus 1758 and T. pini (Uzel 1895). The species are the most numerously and frequently caught in traps in the canopy layer of various Central European forests. Both adults and larvae of Oxythrips spp. may be easily recognized by features present at the end of their abdomen: the former by length of the abdominal segment X; the latter by differences in the length and position of spines. Adults of other the species mentioned above differ in the following features: number of antennal segments, number of setae in the distal part of their first pair of wings, presence or absence of additional setae on abdominal sternites and pleurites, presence or absence of a tooth on the tarsus of the first pair of legs. The main features differentiating larvae of these species (besides T. pini larva which have been hitherto undescribed) are body sclerotisation and length, and shape of the comb surrounding the IXth abdominal segment.

Abstract

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.

Hoplandrothrips famelicus (Priesner, 1926) (Thysanoptera: Phlaeothripidae) - a thrips new to the Polish fauna

Hoplandrothrips famelicus (Priesner, 1926) is recorded for the first time in Poland and the third time in Europe. Adult females and males have been found in galls of Lipara Meigen, 1830 on Phragmites australis. The diagnostic characters, distribution and biology of this species are presented and discussed.

Abstract

Hoplothrips carpathicus PELIKÁN, 1961 was recorded for the first time in Poland in two localities: in the Białowieża National Park and in the Bieszczady National Park. It was captured using IBL2 screen traps at both sites. The diagnostic characteristics of the macropterous females found in Poland were compared with the micropterous holotype described in Slovakia. Key features are illustrated and data on the distribution of this species in Europe is appended
