The helminth community of the Green toad Bufotes viridis (Laurenti, 1768) from the population inhabiting the Caspian basin on the territory of the Republic of Dagestan is characterized. The study was carried out according to the method of full helminthological autopsy. Six species of helminths belonging to two types have been registered: Nematoda (4) and Acanthocephala (2).

REPRODUCTIVE STRUCTURE OF A HEMIPOPULATION OF COSMOCERCA ORNATA (NEMATODA: COSMOCERCIDAE) IN MARSH FROGS PELOPHYLAX RIDIBUNDUS (PALLAS, 1771) (ANURA: RANIDAE) OF SEVERAL PHENOTYPES

Authors: Kirillova N. Y., Kirillov A. A.

The reproductive structure of Cosmocerca ornata (Dujardin, 1845) in marsh frogs (Pelophylax ridibundus (Pallas, 1771)) of both the striata and non-striata phenotypes was studied. Distinctions in the physiology, ecology and behavior of striped and unstriped amphibians have certain influence on the intensity of processes of the host infestation and maturing of C. ornata in frogs of different phenotypes. Analysis of the age structure of the C.
