The Species Composition and Seasonal Dynamics of Thrips (Thysanoptera) Populations on Maize (Zea MaysL.) in Southeastern PolandThrips 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 themFrankliniella tenuicornis(Uzel 1895) andHaplothrips 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 ofF. tenuicornisspecies in their immature stages in the samples, confirmed the role of the maize plant as the host.H. aculeatusprobably chose maize as a food source and substitute plant for breeding.

Water mites (Acariformes, Hydrachnidia, Halacaroidea) were studied in 8 different bogs and fens of Western Siberia. 28 species of Hydrachnidia and 5 species of Halacaridae were found in them. The species composition in the bogs was very different. In the fens the abundance and species diversity were higher than in sphagnum bogs and the fauna were based on spring species. The representatives of the halacarid mites dominated in sphagnum bogs, which were not found in the fens. The specific similarity of the studied bogs was low. At the same time, the peculiarities of seasonal dynamics in bogs and fens were similar and resembled temporary water bodies: high numbers in the spring and an abruptly decline in the summer, with a slight increase in autumn.

The assemblages of herpetobion spiders from four habitats: two seven-year-old burns, spruce-birch and fir-spruce forests, were examined in the Visimskiy Reserve (Sverdlovsk Region) during May-September 2017 using pitfall-traps. The structure of the spiders population of burns significantly differs from that of forests in species composition, total occurrence rate (ind./100 trap-days), seasonal dynamics and composi-tion of the dominant species. Differences in the structure of the population are most pronounced in the summer. In summer spider assemblages of burns, the most abundant are Agyneta allosubtilis, Alopecosa pulverulenta, P. fulvipes, P. lugubris, P. riparia and Piratula hygrophila, in forests - Allomengea scopigera and Haplodrassus soerenseni.

ABSTRACTIn an environment seriously impaired by human interference (draining the reservoir), ecological relationships in a community of copepods and their impact on the transmission of the tapeworm Proteocephalus neglectus La Rue. 1911 were studied. The impairment of the environment resulted in changes in the species composition of the copepod community and in the increased diversity of the copepod species, as well as in a multiple inversion of the dominant and subdominant relationships of the two most numerous copepod species (Cyclops vicinus and Eudiaptomus zachariasi). The structure of the developmental stages of the copepod community, the seasonal dynamics of the number of copepods and the abundance of P. neglectus procercoids have changed. The predominant species in the copepod community and the most susceptible intermediate host of P. neglectus (C. vicinus) was not infected. The infection of copepods decreased by 95% and that of the definitive hosts (Oncorhynchus mykiss) by 97·5% compared with the index values recorded in the previous year.

AbstractIn six sites in the Košice Basin we collected 17,520 larvae of 15 mosquito species during the seasons (April–August) of 2010 and 2011. They were: Aedes vexans (Meigen, 1830), Ae. cinereus (Meigen, 1818) [or Ae. rossicus (Dolbeskin, Gorickaja & Mitrofanova, 1930], Ochlerotatus geniculatus (Olivier, 1791), Oc. refiki (Medschid, 1928), Oc. rusticus (Rossi, 1790), Oc. sticticus (Meigen, 1838), Oc. punctor (Kirby, 1837), Oc. cataphylla (Dyar, 1916), Oc. cantans (Meigen, 1818)[or Oc. annulipes (Meigen, 1830)], Oc. communis (De Geer, 1776), Oc. flavescens (Müller, 1764), Oc. leucomelas (Meigen, 1804), Culiseta annulata (Schrank, 1776), Culex pipiens (L., 1758) [or Cx. torrentium (Martini, 1925)] and Anopheles maculipennis s.l. The objective of the present research was to identify the mosquito larvae species diversity and compare their distribution and density in urban and suburban localities of the monitored territory.

Abstract Ichthyofauna surveys in Diyung, Vomvadung, Khualzangvadung, Tuikoi, and Mahur rivers under Dima Hasao District of Assam resulted in the first report of 21 species of fish belonging to 19 genera, eight families, and four orders. These include Cypriniformes, Siluriformes, Synbranchiformes, and Perciformes. The species composition is highest in Vomvadung River with 11 species, followed by Diyung with eight species, Khualzangvadung with six species, Mohur with three species, and Tuikoi with two species. The conservation status of Systomus clavatus, Tor tor, Neolissochilus hexagonolepis, Neolissochilus hexastichus is near threatened, and Pterocryptis barakensis is endangered.

The new data on seasonal dynamics of species composition, abundance and biomass of molluscs on soft sediments in the corner part of the Sevastopol bay were analyzed. 24 species of molluscs were recorded in 2006-2007. The microdistribution of Mollusca at stations depends on salinity. The trophic structure of molluscs’community was determinated and includes 6 trophic groups.
