Cathaemasia Hians (Digenea, Cathaemasiidae) from Planorbis Planorbis (Mollusca, Gastropoda) in Reservoirs of Central Polissya

The paper presents the description of Cathaemasia hians Rudolphi, 1809 trematode found on the territory of Ukraine in an intermediate host, fresh-water molluscs Planorbis planorbis. We present also a comparison of metrical characters of the studied C. hians cercariae and those described by other researchers.

Cercaria of the Trematode Plagiorchis Mutationis (Trematoda, Plagiorchiidae) from the Pond Snails, Lymnaea Stagnalis, in Ukraine

Morphological characteristics and measurements of Plagiorchis mutationis Panova, 1927 cercaria found for the first time in the intermediate host, pond snail Lymnaea stagnalis in Ukraine are given.

The Slug Mite Riccardoella (Proriccardoella) Oudemansi (Prostigmata, Ereynetidae) from Ukraine

The mite Riccardoella (Proriccardoella) oudemansi (Prostigmata, Ereynetidae) parasitizing the lung mollusks, is redescribed based on numerous specimens from Ukraine. These mites were first found in the fauna of Ukraine in the early 1990th.

Abstract

The paper presents results of the studies on alterations in the structure and functions of mollusc organs under the effect of the trematode Orientobilharzia turkestanica (Skrjabin, 1913) larvae. Destructive changes were observed along with a vast necrosis of the hepatopancreatic gland. Parasitism of O. turkestanica parthenitae and cercariae in L. auricularia causes deep histopathological changes in the tissues. Protein, carbohydrate and fat metabolism disorders result in the weakening of molluscs and loss of their lability, which is essential for adaptation to environmental changes. The latter is confirmed by a high mortality of infected individuals.

Life Cycle of the Trematode Notocotylus intestinalis (Digenea, Notocotylidae) under Natural Conditions in Primorye Region (Russia)

The redia, cercaria, adolescaria and adult trematodes Notocotylus intestinalis Tubangui, 1932 are described. It was established that under natural conditions of Primorye Region, the first intermediate hosts of this trematode are snails Parafossarulus manchouricus and P. spiridonovi. Adult worms were grown in the chicken.

Life Cycle of the Trematode Neodiplostomum oriolinum (Diplostomatidae) under Natural Conditions in Primorye Region (Russia)

The life cycle and developmental stages of the trematode Neodiplostomum oriolinum Oschmarin, 1963 are described. It was experimentally established that under natural conditions of Primorye Region, the first intermediate hosts of this trematode are snails Polypylis semiglobosa, Helicorbis sujfunensis, and the second are tadpoles of Rana dybowskii. Adult worms were developed in chicken and rat. Based on comparative morphological analysis of adult worms developed under experimental conditions and data given in P. G. Oshmarin (1963) paper it is assumed that N. oriolinum and N. paraoriolinum Oschmarin, 1963 are synonyms.
