Diptera (Brachycera) of the agricultural landscape in southern Moravia
Abstract
Material of Brachycera (501 species from 51 families) was evaluated in detail from the ecological view point. The dipterocoenoses were analysed in barley field, field with leguminous plants, windbreak, and a rest of a deciduous forest, and in two ecotones (windbreak edge and forest edge). There was a distinctly higher species diversity and equitability in dipteran communities of non-agricultural ecosystems and their share in the autoregulative processes in biocoenoses at the level of diversified landscape segments. -from Authors

This study was based upon material of the family Tachinidae (Diptera) collected from some uplands of Tokat (Turkey) during 2012 and 2013. In total, 24 species were identified during this study. They are 1 genus and 1 species from the subfamily Exoristinae, 5 genera and 7 species from the subfamily Tachininae, 6 genera and 7 species from the subfamily Dexiinae, 5 genera and 9 species from the subfamily Phasiinae. Among them, Peleteria varia, Linnaemya impudica, Macquartia chalconota, Peribeae tibialis, Periscepsia carbonaria and Prosena siberita were recorded for the first time in Tokat.
Records of 10 species of the families Asteiidae, Aulacigastridae, Milichiidae, Sphaeroceridae from the Czech Republic are presented. Sphaerocera pseudomonilis hallux Roháček & Florén, 1987 (Sphaeroceridae) represents a new addition to the fauna of Central Europe. Two species, Leiomyza birkheadi Gibbs in Gibbs & Papp, 2007 (Asteiidae) and Aulacigaster falcata Papp, 1997 (Aulacigastridae), are reported for the first time from the Czech Republic. The available Czech material formerly identified as “Leiomyza laevigata” is revised and records of true Leiomyza laevigata (Meigen, 1830) are published. New record of Milichiella tiefii (Mik, 1887) (Milichiidae) from Bohemia and of Trachyopella (Nudopella) hem Roháček & Marshall, 1986 (Sphaeroceridae) from Moravia are given. Additional findings of some rare species of Sphaeroceridae are also
presented and the spreading of a recently introduced species, Desmometopa microps Lamb, 1914
(Milichiidae), in South Bohemia is documented.
This study was carried out to determinate the Tachinidae fauna of Sakarya province in 2012- 2013. Tachinids were reared from various hosts and collected by sweeping from various herbaceous plants by trap in region. As a result of this study, 7 genera and 8 species belonging to the subfamily of Exoristinae, 5 genera and 5 species belonging to the subfamily of Tachininae, 2 genera and 2 species belonging to the subfamily of Dexiinae, 4 genera and 6 species belonging to the subfamily of Phasiinae were found. Two species among them were recorded for the first time in Turkey. These are Meigenia incana (Fallen, 1810) and Exorista civilis (Rondani). Twenty one species were identified and identification keys including genera and species belonging to the 4 subfamilies were prepared and the photograph of important distinctive morphological features of body parts of the specimens were taken. Some biological aspects, hosts and distributions were also given.
This study was carried out to determinate the Tachinidae fauna of Sakarya Province in 2012 and 2013. Tachinids were collected in the region by sweeping with nets from various plants. As a result of this study, 7 genera and 8 species belonging to the subfamily of Exoristinae, 5 genera and 5 species belonging to the subfamily of Tachininae, 2 genera and 2 species belonging to the subfamily of Dexiinae, and 4 genera and 6 species belonging to the subfamily of Phasiinae were found. Two species among them, Meigenia incana (Fallen, 1810) and Exorista civilis (Rondani, 1859), were recorded for the first time in Turkey.
In 1998 the Deutsches Entomologisches Institut (DEI) acquired the previously unknown Diptera collection of Dr Carl Friedrich Ketel (1861-1906), a secondary school teacher who was active in his spare time as a botanist and entomologist in Mecklenburg and west Pomerania. The present work opens with a brief sketch of the history of dipterology in the Federal State of Mecklenburg-Vorpommern, and this is followed by an account of Ketel's life and career which have remained largely unknown until now. The revision of this historic collection, which was formed between 1884 and 1903, has only been possible through the collaboration of a team of 41 international specialists. In the main part of the paper, these specialists present their results family by family. Each family treatment has an introduction which contains notes on the morphological, taxonomic and biological features of the family together with an evaluation of that part of the collection. At the same time, new information on individual species or new taxonomic discoveries are presented. Finally, all the species of the family are listed together with their locality and collecting data. Ketel's Diptera collection has been found to contain 7,369 pinned and labelled specimens of 1,455 species in 83 families. As there are very few Diptera collections that contain representative material from north-east Germany, the Ketel collection is of considerable value for local faunistics. Over and above this, it is of significance for dipterological research in Central Europe in general.
This study was carried out to determine the tachinid parasitoids of lepidopterous and heteropterous hosts from some localities in the Kelkit Valley (Amasya, Tokat, Sivas) of Turkey. Eleven species belonging to the subfamily Exoristinae and 9 species belonging to the subfamily Phasiinae were reared. Eurygaster maura L. (Heteroptera: Scutelleridae) for Gymnosoma desertorum Rohdendorf and Corizus hyoscyami (L.) (Rhopalidae) for Elomyia lateralis (Meig.) were recorded for the first time as tachinid/host-couples. Additionally, 6 tachinid/host-couples were recorded for the first time from Turkey.
This paper summarizes data on the response of mosquitoes to changed water regime following extensive water management alterations on the southern Moravian Dyje and Morava rivers. Maximum groundwater level dropped by an average of 90 cm, previous regular floods were prevented, and the area covered by floodplain forests was significantly decreased due to the construction of three reservoirs.
The original mosquito community of temporary water bodies (Aedes) is in retreat both quantitatively and, in places, qualitatively. Of the initial number of six species causing plagues, only Ae. vexans has remained (63.3 per cent), the rest occurring at percentages of only 0.1–4.1 per cent. After flood regulation, the breeding grounds of the species developing in temporary water bodies has filled only during periods of sufficiently high groundwater levels and sufficient saturation of soil with rainfall.
A prospective group in this area includes mosquito species developing in permanent water bodies (Culex, Anopheles, Culiseta, etc.). This group is increasing in numbers and species richness. After the completion of three reservoirs, Anopheles spp. spread throughout the study area. They develop in the waters accompanying the reservoirs, especially in channels rich in vegetation, in which they attain densities of up to 39.9 larvae per 100 cm2 water surface. The drier environment, and drier and warmer climate prevailing in recent years have probably influenced the occurrence of southern species in the area, notably Culex martinii and Uranotaenia unguiculata.
Long-term quantitative collections of mosquitoes enable first note to be made on the possible fluctuation mechanisms, previously obscured by the essential influence of floods on community development.
Published quantitative descriptions of local species assemblages represent a rich and little explored source of information exploring macroecological patterns. We used this source of data to estimate determinants of syrphid species richness in Central Europe. We examined the influence of three census-related covariates and five environmental variables on the observed or standardized (by rarefaction) species richness of 163 local syrphid assemblages. We also compared a large data set collected by a single author with a compilation of various sources. The covariates had mostly significant effects: increasing sample size and increasing sampling effort caused an asymptotic increase in species richness. The most effective collecting technique was entomological net, followed by malaise and colour traps. After taking into account the influence of covariates, the effects of geographical environmental variables (altitude, latitude and longitude) were more important than the effects of habitat variables. Syrphid richness exhibited a hump-shaped response to altitude and a latitudinal peak in the central areas of Central Europe. Our approach illustrates the potential of literature data for studying large-scale variation among local species assemblages.
