A total of 383 fleas of 11 species were collected off 428 bank voles ( Clethrionomys glareolus) captured near Babaevo (59°4′N, 35°8′E). Three of the species recorded ( Amphipsylla rossica, Doratopsylla dasycnema, and Palaeopsylla soricis) were not typical of these rodents, infesting the latter occasionally from other animals, such as the common vole Microtus arvalis and shrews inhabiting adjacent or the same biotopes. Peromyscopsylla bidentata, infesting the bank vole in most part of its range, was recorded only as a single female. Megabothris turbidus was also very rare, being sporadically recorded from May to October; the examined territory probably lies at the northern boundary of its range. The most abundant species, Ctenophthalmus uncinatus, had two peaks of abundance: in April, when adults emerged from overwintered cocoons, and in July. Then their abundance decreased and the last occasional individuals were recorded till December. The year-round parasite Amalaraeus penicilliger was most abundant in winter. Other species were few in number. Adults of Megabothris rectangulatus were recorded from April to August with two peaks of abundance: in April, when they emerged from overwintered cocoons and in July, when the second generation emerged. The univoltine species Peromyscopsylla silvatica emerged in July-August and parasitized till September. Rhadinopsylla integella was the most abundant in October-December, but occasional specimens were recorded in January. The polyxenous species Hystrichopsylla talpae emerged in late July and occurred till September. [ABSTRACT FROM AUTHOR] |
