New species of Polyphemoidea for the Volga reservoirs - Bychek E.A. - The data on distribution of two species of predatory Cladocera, Cornigerius maeoticus (Pengo, 1879) and Cercopagis pengoi (Ostroumov, 1891), in the reservoirs of the Volga are generalized. A short description of their dynamics is given.

Eight-striped cichlasoma - an allochthonous species of cichlid fish (Teleostei: Cichlidae) from Staraya Kuban' Lake - Zworykin D.D., Pashkov A.N. - A new allochthonous species of cichlid fish, Rocio octofasciata (Regan, 1903), from Staraya Kuban' Lake (Krasnodar City), is determined and described. Ecology of this species in various habitats including native range, South USA and Staraya Kuban' Lake is discussed. It has been suggested that Rocio octofasciata formed the self-sustaining population in Staraya Kuban' Lake and represents the established species. Further studies of this alien cichlid have been considered.

First finds of Echinothrips americanus Morgan (Thysanoptera: Thripidae) on the territory of Russia - Izhevskiy S.S., Mironova M.K. - This paper describes a new for Palaearctic fauna polyphagous species, an Echinothrips americanus Morgan. which was included into the signal list of plant pests of quarantine significance for the countries of the European and Mediterranean Organization for Plant Protection in 1999. Life cycle, biology characters and distribution of the species are given. Predatory insect species, Franklinothrips vespiformis, Orius spp., and Chrysopa spp., some microbiological and natural substances seem to be effective against this invasion species. Echinothrips americanus Morgan was found in greenhouse of the Botanic Gardens of the Botanical Institute of the RAS in 2005. So, in Russian fauna of insects damaging greenhouse plants, a new invasion species has appeared.

Agrilus planipennis Fairmaire on Moscow ash trees - Izhevskiy S.S., Mozolevskaya E.G. - An invasion species of an aggressive plant pest, an ash narrow-body borer (ANBB), Agrilus planipennis Fairmaire (= A. feretriue Obenberger, A. marcopoli Obenberger), was found and identified on Moscow ash trees for the first time in 2005. A broad shrinkage of Moscow ashes has been registering since 2004 and ANBB is considered to be the main reason for this process. Short description of the insect structure, biology and usual areals of distribution is presented. A Palaearctic Oobius zahaikevitshi Trjapitzin (Trjapitzin, 1989), which parasitizes in the eggs of narrow-body borers, can be considered as an available species for ANBB pest control. It seems likely that ANBB was brought at the beginning of 1990s with planting stock from North America; carrying of insects with wooden tare from China directly could be another way of invasion. The species ought to be viewed as a quarantine one.

Distribution of new and rare species of zooplankton in reservoirs of the upper Volga at the beginning of the XXI century - Lazareva V.I. - This paper demonstrates examples of distribution of some rare zooplankton forms: Asplanchna henrietta Langh (Rotifera) and big (adult individuals size >1 mm) pelagic shrimps – Diaphanosoma orghidani Negrea and Arctodiaptomus laticeps Sars. The burst-like character of an abundance dynamic of this species is shown. Creation of the cascade of lake-like reservoirs is viewed as the main cause of the new and rare zooplankton species invasion in the Upper Volga.

Canal Catfish in the upper and middle course of the Bolshoy Egorlyk river - Mishvelov E.G., Oleinikov A.A. - Literary data analysis and field studies showed the presence of the canal catfish in ichthyofauna of not only the lower, but also the middle and upper course of the Bolshoy Egorlyk river (stavropol territory). For a final conclusion about this species naturalization in the Bolshoy Egorlyk river, additional population studies are necessary and advisable.

About distribution of Phragmites altissimus (Benth.) Nabille (Poaceae) - Papchenkov V.G. - The taxonomy, synonymy, comparative structure description and distribution dynamics for 3 species of the genus Phragmites Adans.: Ph. communis Trin., Ph. isiaca (Del.) Kunth, Ph. serotina Kom., and for a relative and invasive in some areas species, Ph. altissimus, are given for the former USSR territory. Further observations for distribution of Ph. australis (Ph. communis) and Ph. altissimus are necessary for their competitative behavior study, which will allow the obtaining a material about behavior of genetically modified plants with enhanced vegetation mass productivity in natural conditions.

Introduction of striped leaf-eating insect Zygogramma suturalis (Coleoptera, Chrysomelidae) in Stavropol territory - Pushkin S.V. - Leaf-eating insect Zygogramma suturalis F. (Coleoptera, Chrysomelidae) was introduced into Russia from Canada and USA for control of invasion weeds – ambrosias (Ambrosia artemisiifolia L., A. psilostachya D.C.) in Stavropol territory in 1978. Despite the initial success in introduction ("local population wave" – elimination of ambrosia within one vegetation period), the system "leaf-eating insect – ambrosia" had come to equilibrium 10 years later. Ambrosia inhabits agrocenosis mainly, where crop rotation is inherent. Rotation of crops does not allow phytophage to accumulate high density of population. So, the success of biological method of weed control was achieved in stabilized biocenoses and possibility of successful introduction is lowering with decrease of stability.

Naturalization of tubenose goby Proterorhinus marmoratus (Pallas, 1814) (Pisces: Persiformes: Gobiidae) in Rybinsk reservoir - Slynko Yu.V. - The fact of appearance of the Ponto-Caspian tubenose goby in the Rybinsk Reservoir is described for the first time. The data on dislocation and number of population, size-age structure, and feeding are given. Morphological description of the tubenose goby in the Rybinsk Reservoir is presented. The rate of naturalization of tubenose goby in the Upper Volga Basin is analyzed.

The first finding of the Black Sea snail Lithoglyphus naticoides (Gastropoda) and associated with it species-specific Trematoda in the Upper Volga basin - Tyutin A.V., Slynko Yu.V. - After the first finding in the Volga River delta in early 1970s, the Ponto-Azov snail Lithoglyphus naticoides had expanded its range towards the northern water bodies of the Upper Volga basin. During 2004-2007 the new populations of L. naticoides with a high level of infection by specific trematode species were found in the Cheboksary and Rybinsk reservoirs. Besides, metacercariae of the genus Apophallus associated with L. naticoides were marked in the fishes of the Gorky and Ivankov reservoirs.
