The Norwegian species of Aphelinus Dalman, 1820 (Hymenoptera: Aphelinidae) are reviewed, and a total of 8 species are recorded. The 3 species Aphelinus abdominalis (Dalman, 1820), A. chaonia Walker, 1839, and A. varipes (Förster, 1841) have previously been recorded from Norway, while A. mali (Haldemann, 1851) and A. asychis Walker, 1839 represent new records for the country. The 3 species A. elvestueni sp. nov., A. odin sp. nov., and A. paluscolus sp. nov. are described, illustrated, and compared with closely related species. An illustrated key for the identification of the females of Norwegian Aphelinus is presented. © TÜBİTAK.

Four species of springtails and four species of oribatid mites were identified as new records for the Georgian fauna from different regions of the country: Coecobrya tenebricosa (Folsom, 1902); Entomobrya muscorum (Nicolet, 1842) Rondani, 1861; Heteromurus major (Moniez, 1889); Pseudosinella octopunctata Börner, 1901; Austrocarabodes ensifer (Sellnick, 1931); Jacotella frondeus (Kulijev, 1969); Lasiobelba pori (Vasiliu & Ivan, 1995); and Bipassalozetes sabulosus (Shtanchaeva, 1986). Moreover, L. pori is the first record for the Caucasian fauna. With these new records, the number of springtail species known from Georgia increases to 97 and the number of oribatid mite species in Georgia exceeds 530. © TÜBİTAK.

The phenology and survival of beech scale, Cryptococcus fagisuga Lindinger (Hemiptera: Eriococcidae), were investigated in part of its native range (Caucasus Mountains, Georgia) and in an invaded area (Massachusetts, USA). Despite nearly identical growing seasons (as measured by cumulative day-degrees), the scale was found to be bivoltine in the Caucasus Mountain region but univoltine in Massachusetts. In Georgia, scales overwintered as adults, whereas in Massachusetts, 1st instar crawlers were the overwintering stage. In Massachusetts, protective cages increased scale survival over a year-long period, but the effect was not great and was presumed to be due to exclusion of generalist predators, not specialized natural enemies. There was no effect of caging on survival in Georgia, and no support was found for the hypothesis that specialized natural enemies might exist in the scale's native range that might be imported for biological control of the pest in the United States. Rather, it appears that selection for resistance in American beech (Fagus grandifolia Ehrhart; Fagales: Fagaceae) may offer the best chance to restore healthy stands of American beech in North American forests.

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.

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 species Aenasius bambawalei Hayat is considered as a junior synonym of A. arizonensis (Girault). Nipaecoccus viridis is recorded as a new host for Leptomastix longicornis. In addition, available information for each species and comments on taxonomy, biology, and geographical distribution are included. © TÜBITAK.

Oribatid mite diversity along an altitudinal gradient from 10 m to 850 m a.s.l was investigated on the twigs and leaves of Rhododendron ponticum L. in Mtirala National Park. Forest floor sampling (mineral soil and litter) was also performed in the same locations. Altogether, 77 species of oribatid mites were identified. 31 species were found in the canopy and 64 species were found in the mineral soil and litter. Juveniles made-up 7.6% of the canopy fauna. Ommatocepheus ocellatus (Michael, 1882), was a new finding for Mtirala National Park. Steganacarus (Tropacarus) patruelis Niedbala, 1983 was the most numerous species found on twigs and leaves. Almost the whole canopy fauna (94%) belonged to higher oribatids (Brachypilina) and the lower oribatids were only represented by S. patruelis and Camisia segnis (Herman, 1804). Canopy fauna was separated from those found on the ground supporting the importance of both habitats in maintaining overall biodiversity. The highest number of individuals and the highest number of species was found on mid-altitudes, decreasing with increasing elevation. There was no difference in species richness between twig and leaf habitats, whereas abundance was much higher on twigs. We showed that rhododendron understory harbored well established and abundant oribatid fauna preserving rare and unique species that enhance regional biodiversity. © 2015, Les Amis d'Acarologia.

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.

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.
