The life cycle of Ixodes persulcatus lasts 3 years in the conditions of the Leningrad province (North-West Russia), the development of each phase taking a year. The normal age of the taiga tick is 3 years. The calendar age of larvae and nymphs reaches 11-12 months under favorable abiotic and biotic factors, while the calendar age of adults does not exceed 11 months. At the preimaginal phases of development the ticks that breed in August can feed before or after winter. However, their metamorphosis begins and reaches completion within the same timeframes (from late June to early August) and lasts for about 30-50 (60) days. The survival rate of hungry and engorged larvae and nymphs after wintering is quite high (88.6-100 %). We explain the low activity of larvae and nymphs in late summer and autumn by incomplete development. Morphogenetic diapause of engorged larvae and nymphs interrupts digestion but not metamorphosis which starts only in late June and July after the complete absorption of blood from the gut cavity.
The present study was conducted on bats from different locations in Turkey. Of 33 bats, belonging to 10 species, 10 individuals (30.3%) of four species were infected with gamasine mites. Fifty-three mites belonging to 2 families (Spinturnicidae and Macronyssidae) were collected. The spinturnicid Spinturnix myoti (Kolenati) was the most abundant species (27 specimens) and only recorded on Myotis nattereri (Kuhl). The species Steatonyssus periblepharus (Kolenati) and the genera Steatonyssus, Macronyssus and Ancystropus are reported from Turkey for the first time, while new host and distributional data are presented.
First data on parasites from bats (Chiroptera) in Karelia are presented. Bats were captured at hibernacula in Lahdenpohsky and Sortavalsky Districts of Karelia in March 2010 and February 2011. Partial helminthological dissection was applied to 12 bat individuals of three species: northern bat Eptesicus nilssonii Keyserling & Blasius, 1839 (8 specimens), brown long-eared bat Plecotus auritus (Linnaeus, 1758) (1 spm.), and Brandt's bat Myotis brandtii (Eversmann, 1845) (3spm.). Ectoparasites were collected from the bats captured in March 2010: E. nilssonii -6 individuals (3 from each of Sortavalsky and Lahdenpohsky Districts), P. auritus -1 ind. (Lahdenpohsky District), M. brandtii -1 ind. (Sortavalsky District). The surveys revealed 14 species of parasites from different taxonomic groups. All the parasites were found in Karelia for the first time. Helminthes were represented only by trematodes of 3 families: Plagiorchiidae (Plagiorchis vespertilionis, P. koreanus, P. muelleri), Lecithodendriidae (Lecithodendrium linstowi, Paralecithodendrium chilostomum, P. skrjabini), and Pleurogenidae (Parabascus magnitestis). Ectoparasites in the samples include gamasid mites of the families Spinturnicidae (Spinturnix kolenatii, S. plecotinus) and Macronyssidae (Macronyssus crosbyi, M. cyclaspis), chigger mites of the family Trombiculidae (Leptotrombidium sp.), and fleas of the family Ischnopsyllidae (Ischnopsyllus hexactenus, Ischnopsyllus sp.). All the parasites are bat specialists, known to occur in various parts of Russia and Europe.
This paper reports on four species of the genus Antennoseius Berlese phoretic on ground beetles (Coleoptera: Carabidae) from Russia: Antennoseius (Vitzthumia) bregetovae Chelebiev; Antennoseius (Antennoseius) bullitus Karg; A. (A.) pannonicus Willmann and A. (A.) ponticus Trach and Makarova. Moreover, we provides additional morphological information and new illustrations for two species of Antennoseius Berlese – A. (V.) hyperboreus Nikolsky and A. (V.) koroljevae Chelebiev based on the type series to facilitate species delimitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
