T1  - Zur Ektoparasitenfauna der Fledermäuse in Sachsen Anhalt : Ectoparasites of bats in Saxony-Anhalt
N2  - During the summer 2010 several mist nettings for the monitoring of bat species were performed in Saxony-Anhalt. Captured individuals were tested for ectoparasitic infestation. The aim was to update the fauna of ectoparasites of this state and to collect data on the distribution of individual species. Regarding this, results of previous surveys are summarised. In the present study nine out of thirteen bat species were found to be infested with a total of one flea species, one species of bat flies and eight species of mites. The infestation with fleas was below the expectations. Six spinturnicid mite species out of those occurring in Germany could be ascertained for Saxony-Anhalt. These are Spinturnix acuminatus (Koch, 1836), S. andegavinus (Kolenati, 1857), S. helvetiae Deunff, Keller & Aellen, 1986, S. mystacinus (Kolenati, 1857), S. plecotinus (Koch, 1839) and S. puncata (Sundevall, 1833). Details about the infestation with parasites (abundances) of the respective bat species are presented. Further information on the biology of spinturnicid mites are given and infestation characteristics are compared with those of other surveys. Keywords: ectoparasites, bats, Chiroptera, gamasine mite, Acari, Spinturnix, Ischnopsyllidae, Nycteribiidae, Saxony-Anhalt, Germany

T1  - Zur Fähigkeit von Ektoparasiten der Fledermäuse ihre Wirte aktiv aufzusuchen
N2  - Active host-searching in bat ectoparasites. As a pilot study, this paper discribes the mobility of ectoparasites after removing from their hosts. Spinturnix acuminatus (Koch, 1836)(Acari, Spinturnicidae) a permanent stationary bat mite normally survives the removing only a few hours. This species moves easily on the patagium or on human skin. In contrast, on other surfaces the movements of this species seems to be less orientated and it is unlikely that the mite can reach a host in some distance. Nycteribia kolenatii Theodor & Moscona, 1954 (Diptera: Nycteribiidae) a bat fly, shows excellent movements in the fur of its host. The specimens survive the removing from the host several days. The ability to clamber up a wall was tested with a rough clay brick. The bat fly achieves only 9,6 cm on average. This result does not support good abilities for host searching in this species. Bat fleas (Siphonaptera: Ischnopsyllidae): Ischnopsyllus elongatus (Curtis, 1832), I. hexactenus (Kolenati, 1856), I. simplex (Rothschild, 1906)and other species survive the removing from their hosts several days. In case of a vertical barrier they showed a stereotype upside climbing, followed by a horizontal appetitive behavior. The fleas were climbing a distance in the upside of 6,45 m on average(1,2-21,68 m). As excellent climbers bat fleas are able to overcome edges and slopes and to crawl on the ceiling. Therefore, it seems to be no problem for a flea to parasite any bat in a resting room. Additionally, some bugs (Cimex lectularius Linnaeus, 1758) were examinated. They run with a speed of 63 cm per minute and were able to climb easily on the brick. On average their stretch of way achieved 2,85 m in ten minutes.
