Summary
In the North-West of the USSR, the rate of invasion of the pine
marten (Martes martes L.) by the pulmonary nematode filaroides ranged from
27.0 to 66.6% (mean 50.3%) in the period 1957-58 to 1967-68; in some
regions it was 43.5-53.1% (maximum in Karelia).
There was a sharp drop in
invasion in years with a good harvest of Sorbus berries.
On average,
females were less infected than males.
Young-of-the-year were infected
more (61.0%) than adults (47.5%).
Infection by Skrjabingylus ranged from
62.5 to 85.3% in the different regions (being higher in the north than in
the south).
90.4% of the population were infected by the two species of
helminths. The mean invasion by Skrjabingylus was from 5.4 to 13.2%;
decreasing at the end of the year.
Poorly fed martens were more heavily
infected.
To date, 19 species of helminths have been recorded in the p~e
marten (Troitskaya 1967).
The most frequent and numerous of these are the
pulmonary nematodes Filaroides martis Werner (1782) and nematodes parasitic
in the frontal and maxillary (Highmore)(a) sinuses, Skrjabingylus petrowi
Bageanov (1936) and ~. nasicola Leuckart (1842; Petrow 1927). These j
helminth species are distributed everywhere. The literature records
