Gyűrűfű poloskanépessége (Heteroptera) három Biodiverzitás Nap alapján

The author studied the Heteroptera fauna of a 1 km2 area near the eco-village of Gyűrűfű (east Zselic region, Southern Transdanubia) during three Hungarian Biodiversity Days. The material collected by several entomologists by different methods contains 207 species, representing about 24 percent of Hungarian fauna. Among the collected species were found some rare ones, e.g. Lygocoris viridis, Criocoris nigripes, Himacerus boops, Aradus brenskei and Scolopostethus puberulus.

Water bugs (Heteroptera) in small water bodies located in Olsztyn

Abstract The study was conducted on 16 water bodies located in Olsztyn, most of them natural and dominated by astatic ones (dystrophic, eutrophic, and artificial with elevated mineralization levels). Heteroptera was identified to 32 species represented by five synecological groups, i.e., species typical of dystrophic water bodies (Cymatia bonsdorffi, Hesperocorixa linnaei, H. moesta, H. sahlbergi, Gerris lateralis, G. sphagnetorum, Hebrus ruficeps), lacustrine species (Gerris argentatus, Aquarius paludum), halophilous species (Cymatia rogenhoferi, Paracorixa concinna, Gerris thoracicus), psammophilous and argilophilous species (Sigara lateralis) and eurytopic species typical of small water bodies (18). It was found that the degree of permanency of astatic water bodies affects both the species diversity and abundance of the Heteroptera fauna. Migrations play a crucial role with respect to the colonization of newly-formed bodies of water and to the abandonment of those that are drying up.

Contribution to Heteroptera fauna of Khorasan Razavi province of Iran.

1Summary In this study, 81 species belonging to seventeen families of Heteroptera from Khorasan Razavi province of Iran were identified. Ten species of them were identified as the first record for Iran and 20 species were also identified for the first time from Khorasan Razavi province. The remaining 51 species have been reported from Khorasan province and their additional distribution areas were given in this paper. Among these species Eurydema ventrale (Kolenati, 1846), Rhaphigaster brevispina (Horvath, 1889), Oxycarenus hyalinipennis (Costa, 1847), Gerris costae (HerrichSchaeffer, 1850) and Holcostethus capitatus (Wolff, 1801) were determined as prominent species, respectively.

Alien True Bugs of Europe (Insecta: Hemiptera: Heteroptera)

This paper reviews the alien (non-native, non-indigenous, exotic) true bug (Heteroptera) species in Europe. Forty-two established alien Heteroptera are recognized, of which 12 species are alien to Europe (originating outside Europe: eight from North America, three from the Eastern Palaearctic, one from New Zealand), 24 species are alien within Europe (translocated within Europe), and six cryptogenic species are of unknown origin. Since 1990 an approximate arrival rate of 7 species per decade has been observed. A recent trend of increased introductions from North America to Europe is suggested. The most important pathway of alien Heteroptera is translocation as contaminants (49 %), usually with ornamental plants, followed by unintentional introduction through natural dispersal (unaided) across political borders within Europe (28 %), and translocation as stowaways within a transport vector (21 %). The taxonomic composition of the alien Heteroptera of Europe is dominated by Miridae (17 species, 40 %), Tingidae (8 species, 19 %), and Anthocoridae (5 species, 12 %), all of which are overrepresented compared to the native European Heteroptera fauna. More than half of the species are phytophagous (24 species, 57 %) and the advantage of trophic specialization in invasion success is discussed. Most species are currently known to occur in the Czech Republic (19 species) and Germany (17 species), followed by Western European countries (Belgium 15 sp., France and United Kingdom 14 sp. each, and Netherlands 13 sp.), resulting in an apparent (north)west–(south)east gradient probably reflecting horticultural tradition in Europe. No unambiguousevidence exists so far for negative ecological or economical impacts, but more research is needed to investigate possible effects. Introductions of alien Heteroptera to and within Europe will increase, and deserve further consideration.

A new notion on the heteropterofauna (Insecta: Hemiptera, Heteroptera) from the Pliocene of Willershausen (N Germany)

Mainly based on collections from Willershausen (Lower Saxony, North Germany), the Pliocene Heteroptera fauna of West Europe is briefly revised. The present compilation includes a checklist with taxonomic and systematic corrections ofJordan’s (1967, 1969) type materials. Naucoroid water bugs of the family Aphelocheiridae are distinguished and the extinct species of the genusAphelocheirus are redescribed. The new genusWillershausenia n.gen. (type species:Nabis strausi Jordan, 1969) is defined and transferred to the coreoid family Alydidae.

New records of Heteroptera from Serbia (Insecta: Heteroptera, Tingidae)

The Serbian fauna of Heteroptera is increased by four new species from the family Tingidae. These species are: Catoplatus fabricii (St?l), Copium teucrii teucrii (Host), Derephysia cristata (Panzer), and Dictyla convergens (Herrich-Schaeffer). The paper also includes a summary of literature data on the heteropteran biology and distribution.

Southward Extension of the Arctic Zone

Many of the Arctic species live above timberline in mountainous areas far to the south of the Arctic. We have made collections in such areas a t two places in North America, the Front Range of Colorado and the Banff National Park area in Alberta.Because of a geological accident, the existence of hundreds of square miles of peneplain at and above timberline (11,500 to 13,000 ft.), Colorado has a very extensive Arctic fauna. However, the main mountain mass in Colorado is far removed from the Arctic and isolated by at least a hundred miles of prairie and forest. The fauna above timberline in colorado is composed of about one third truly Arctic species, one half widespread Cordilleran species, and a small number of endemic species derived from the local fauna in Colorado. Perhaps the most characteristic difference between the insect fauna of the Colorado tundra and that of the Canadian Arctic tundra is the occurrence of a rich fauna of Heteroptera in the Colorado tundra, contrasting with an almost total lack of this group in the Canadian Arctic. Vegetationally the story is similar, the outstanding characteristic of the Colorado tundra being the almost complete lack of Ericaceae.
