For these purposes morphological characters of adults and second stage larva of some populations coming from various regions of Poland were compared. They were studied using cluster analysis and principal component analysis for selecting the significant features separately for females and males. For adults the differences most useful for taxa separation include previously described features, such as the colour of the third antennal segment, the number of distal setae on the first vein of the forewing (for females and males) and new features: the shape of the microtrichial comb on the posterior margin of tergum VIII, and the number of discal setae on abdominal sterna V and VII (females); the length of antennal stylus, the sculpture of the tenth sternum, and the width of pore plates on abdominal sterna V and VII (males). For larvae, the main differences pertain to the number and fusion of sclerotized plates on the pronotum, the degree of developing microtrichia on plaques of tergum and sternum VIII and the differences in sclerotisation of abdominal terga IX and X. The earlier known and the new morphological characteristics of females, males and larvae supported by statistic analyses lead us to believe that the previous taxonomic status-as separate species (T. atratus HALIDAY and T. montanus PRIESNER) was correct.

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 IX th abdominal segment.

Six of the species were present in all six regions, and 36 species in only one of them. The richest fauna (59 spp.) was located in the vicinity of Iwonicz Zdrój (the Low Beskid Mts.), followed by that of the forests in the Sandomierz Basin (47 spp.); a similar number of species were present in the Roztocze region (30 spp.) and the vicinity of Lesko (the Sanocko-Turczañskie Mts.-32 spp.). The smallest number of species were reported from beech forests of northern slopes of the Babia Góra massif (23) and the Ojców National Park (18). Altogether 27 arboricolous species were recorded, among them six were mycophagous. Using specific methods that connect the presence of thrips with particular favourable micro-environmental habitats, larvae and adult thrips were collected from their host plants. These methods made it easier to locate particularly rare and vulnerable species within the Polish fauna, such as: Thrips crassicornis Bagnall, Scolothrips uzeli (Schille) and Haplothrips crassicornis (John). We recognized that T. crassicornis Bagnall and T. fulvipes Bagnall are characteristic of beech forests, although the former is already known from southeastern Poland. Numerical analyses UPGMA and PCA were used to explore the similarities among species composition of thrips assemblages occurring in the studied regions.

Thrips species composition and seasonal abundance was studied on maize crops during two seasons (... more Thrips species composition and seasonal abundance was studied on maize crops during two seasons (2006-2007), in southeastern Poland. Altogether 21 species have been identified, among them Frankliniella tenuicornis (Uzel 1895) and Haplothrips aculeatus (Fabricius 1803) which are a graminicolous species and were eudominants, comprising 96.8% in 2006 and 82.0% in 2007 of all collected specimens. Other species occurred only in low numbers. The frequent and numerous presence of F. tenuicornis species in their immature stages in the samples, confirmed the role of the maize plant as the host. H. aculeatus probably chose maize as a food source and substitute plant for breeding.
Background. Thrips constitute a group of common maize pests in Poland. Although in recent years t... more Background. Thrips constitute a group of common maize pests in Poland. Although in recent years their population and harmfulness in maize fields have increased, they are still not covered by chemical control due to the lack of approved insecticides. Material and methods. A study was carried out in 2010-2012 in southeastern Poland to test the potential indirect effects of non-selective seed dressings and foliar insecticides applied in the spring to control the frit fly (Oscinella frit L.) on the population of thrips without the need for separate treatments. Seed dressings containing imidacloprid (Gaucho 600 FS and Couraze 350 FS) and methiocarb (Mesurol 500 FS), as well as foliar insecticides containing lambda-cyhalothrin (Karate Zeon 050 CS) and a mixture of thiacloprid with deltamethrin (Proteus 110 OD) were used in the experiment. Results. In the study years thrips infested maize plants from mid-May to the first ten days of October. They were most abundant from the end of June to mid-August, with a single population peak between 11 and 20 July. All the tested insecticides used in spring to control O. frit had an indirect insecticidal effect on thrips. The highest effectiveness of seed dressings and foliar insecticides was observed until mid-June, which did not allow for the effective protection of maize plants against feeding thrips. Conclusion. The insecticidal effect of the tested products ended before the most abundant occurrence of thrips, and, therefore, these pests have to be controlled separately with chemical treatments on later dates.

Up to now 41 thrips species have been noted from the former and 125 from the latter mountain chain. From among 128 listed species Oxythrips tatricus is regarded as Carpathian endemic and Thrips trybomi, Haplothrips alpicola, H. alpestris, H. propinqus are connected with mountainous regions; additionally T. brevicornis and T. vulgatissimus have Boreo-Montane range.
