In Georgia, crucian carp Carassius carassius (Linnaeus, 1758) was known from only one locality after Kesslers record (1877-1878) with no new findings until 1985. Since then C. carassius rapidly and simultaneously invaded almost all water bodies of Georgia. In 2004, it was for the first time noted that this invasive Carassius sp. could not be a C. Carassius, but was a form of Carassius gibelio (Bloch, 1792). However no further data is available about this invasive species in Georgia. The aim of the present study was to investigate taxonomic status of Carassius sp. in Georgia using mtDNA phylogenetic analyses and morphometric study of truss network system. Genetic analysis revealed that invasive Carassius sp. is closely related to the C. gibelio from Turkey and other countries. In contrast, morphometrically Carassius sp. from Georgia can be easily differentiated from those of Turkey indicating high intraspecific variability. This is the first time discussion on the current knowledge of the present distribution of invasive carp in Georgia with identifying current problems and future research directions needed. © 2013 Current Zoology.

Myzus persicae (Sulzer) is an economically important agricultural pest with over 500 known host plants in the world. The present study recorded the major parasitoids found parasitizing M. persicae on sweet pepper (Capsicum annuum [L.]) crops in greenhouses in Himachal Pradesh, India. Three species of hymenopteran parasitoids were reared from M. persicae from this source: Aphelinus asychis Walker (Aphelinidae), Aphidius matricariae Haliday (Braconidae), and Aphidius ervi (Haliday) (Braconidae), with parasitism rates per sample date ranging from 2.3-38.6%, 4.8-58.2%, and 2.9-28.4%, respectively, during 2011-2012. This is the first report of parasitoids associated with M. persicae in greenhouse environments in India. The present findings suggest that the management of M. persicae could be possible with the addition of augmentative releases of these parasitoids, which should help reduce pesticide use in Indian vegetable production greenhouses. © 2013 Springer Science+Business Media Dordrecht.

The study of Japanese encyrtids has been started with desctiption of first new species by Howard in 1898. Later many authors devoted their attention to the study of Encyrtidae in Japan. Almost all type specimens of Encyrtidae, described by Tei Ishii and Tetsusaburo Tachikawa, were examined, and all Encyrtidae recorded from Japan, which were available in Japanese collections, are revised. Fifty-two genera and 150 species were recorded to date from Japan. Five new species are described and illustrated: Aphidencyrtoides tachikawai Japoshvili sp. nov., Leptomastix teii Japoshvili sp. nov., Psyllaephagus enokicola Japoshvili sp. nov., P. higashiurai Japoshvili sp. nov. and P. kamitanii Japoshvili sp. nov. One genus, Parablastothrix Mercet, 1917, and five species, Adelencyrtus comis (Noyes & Ren, 1987), Anagyrus bicolor Noyes & Hayat, 1994, Leptomastix auraticorpus Girault, 1915, Parablastothrix maritima Logvinovskaya, 1981, and Syrphophagus aeruginosus (Dalman, 1820), were recorded for the first time from the country. Nine new synonymies are established: Aschitus Mercet, 1921, syn. nov. of Microterys Thomson, 1876; Anicetus eous Trjapitzin, 1965, syn. nov. of A. annulatus Timberlake, 1919; Blastothrix kermivora Ishii, 1828, syn. nov. of B. erythrostetha (Walker, 1847); Cerchysiella togashii Tachikawa, 1988, syn. nov. of Bethylomimus academus Trjapitzin, 1967; Cheiloneurus japonicus Ashmead, 1904, syn. nov. of Ch. claviger Thomson, 1876; Epitetracnemus Girault, 1915, syn. nov. of Adelencyrtus Ashmead, 1900; Ericydnus japonicus Tachikawa, 1963, syn. nov. of E. longicornis (Dalman, 1820); Eugahania mongolica Hoffer, 1970, syn. nov. of E. yanoi Tachikawa, 1956; Leptomastidea rubra Tachikawa, 1956, syn. nov. of L. bifasciata (Mayr, 1876).

Two species of the genus Helix are widespread in Georgia: H. Lucorum has a Mediterranean distribution whereas H. buchii is a Caucasian endemic typically associated with broadleafed forests. In spite of their sympatry within Georgia, they are never syntopic. Furthermore, in contrast with H. buchii, H. Lucorum is mainly found in areas subject to human disturbance. Another large helicoid species, Caucasotachea calligera, is widespread in Georgia and usually co-occurs with either Helix. The distribution patterns of these species suggest that interspecific competition might play an important role in shaping the distribution of the two Helix species. In order to see whether their ecological niches were different enough to provide such a distribution pattern, I used predictive ecological niche models (ENM) based on the Maximum Entropy algorithm. ENMs showed that the niches of these species in Georgia were significantly different but not fully separated (∼15-36% overlap). The distributional pattern of H. Lucorum should not be considered truly natural in Georgia and may be anthropogenic. The fact that the two Helix species never co-occur may result from factors other than ecological niche differentiation at any macro scale. Since competition remains the most useful and informative assumption to explain the distributional pattern of these congeneric species, microhabitat requirements also need to be tested as a potential driver. © 2014 The Author 2014.
