The mud snail (Galba truncatula). Ecology, parasitism and control. Saarbrücken: Lambert Academic Publishing, p. [Google Scholar] Dreyfuss G, Vignoles P, Rondelaud D. Present decline in the number and size of Galba truncatula and Omphiscola glabra populations, intermediate hosts of Fasciola hepatica, on the acidic soils of Central : Gilles Dreyfuss, Philippe Vignoles, Daniel Rondelaud. The authors study the influence of several factors: temperature, drying up of ground, bodily volume of intermediary host on development of the redial generations of Fasciola hepatica in Lymnaea truncatula. Three redial generations are seen in Lymnaea truncatula, whatever environmental by:

We studied the population genetic structure of the freshwater snail Galba schirazensis (Küster, ), a potential vector of infectious diseases such as schirazensis has now a worldwide distribution but a poorly known origin because this species has been distinguished only recently from the morphologically similar and cosmopolitan Galba truncatula (O.F. Müller, ).Cited by: 3.   The present study aims to assess the epidemiological role of different lymnaeid snails as intermediate hosts of the liver fluke Fasciola hepatica in Belgium and Luxembourg. During summer , lymnaeid snails were collected from ponds distributed in 5 clusters each including 25 ponds. Each cluster was located in a different biogeographic area of Belgium and by:

of the snail, Lymnaea truncatula, intermediate host of the liver fluke, Fasciola hepatica. The diet of the vector snail was studied and the algal types ingested by L. truncatula were determined. Algae were found to be a conspicuous component of the snail's diet. Diatoms occurred frequently in . Light Microscopy (LM) and Scanning Electron Microscopy (SEM) were used to study the egg and miracidium of Fasciola gigantica and redia, cercaria and metacercaria from field infected Lymnaea (cailliaudi) natalensis snails, to analyze the differences between eggs and intra-molluscan stages of F. hepatica and F. gigantica in a zone of sympatry. The egg of F. gigantica has an umbilicus-like.

We have conducted a thorough study of the mating system of Lymnaea truncatula, the intermediate host of the liver fluke, using three approaches: (i) a population genetics study, (ii) controlled.

Some species are used in aquaculture under the name Melantho snails. Lymnaea is the type genus of the family Lymnaeidae. Species. Species within the genus Lymnaea include.

peregra in laboratory conditions have paid attention to foods, temperature and water quality, and these directly affect the life history traits, such as growth rate, age of maturation and occurrence of the herbicide, simazine in freshwater. 1. Introduction. Fasciolosis, caused by Fasciola hepatica, is a serious parasitic disease in ission depends on susceptible definitive hosts (e.g.

sheep and cattle) and appropriate habitats for development of both the parasite larvae and the intermediate host Lymnaea snail requires a moderate climate and moisture for survival and reproduction (Thomas, ).Cited by: In this issue the biology and the ecology of the snail are described, based on both field observations and laboratory studies.

Basically, the biology, and the ecology of Lymnaea auricularis rubiginosa are similar to those of other species of lymnaeid snails reported by previous workers: File: pdf: Sitasi (tidak ada sitasi) Referensi: 1. Austropeplea (Lymnaea) viridis This snail is similar to Austroplea (Lymnaea) tomentosa, but the shell is longer and has four to five whorls.

An introduced species from the Pacific Islands, it is the intermediate host of liver fluke in Papua New Guinea, and now also in Australia.

Pseudosuccinea (Lymnaea) columella This snail is also similar to. A comparison of environmental associations shows that the majority of common freshwater gastropods (e.g. Lymnaea truncatula, Bathyomphalus contortus, F=32%) preferred dam reservoirs and old river beds while they avoided the fish ponds (e.g.

peregra, F=−3%), mining subsidence pools (e.g. contortus, F=−10%) and clay pits (P. planorbis Cited by: Folia Parasitologica 61[2] () | DOI: /fp Lymnaea cubensis, an experimental intermediate host for Fascioloides magna Philippe Vignoles 1, Adam Novobilský 2, Johan Höglund 2, Martin Kašný 3,4, Jan Pankrác 3, Gilles Dreyfuss 1, Jean-Pierre Pointier 5, Daniel Rondelaud 1 1 INSERMFaculties of Medicine and Pharmacy, Limoges, France.

Here, we investigate which ecological factors affect the evolution and maintenance of self‐fertilization in the freshwater snail, Galba truncatula (previously named Lymnaea truncatula).

This hermaphroditic species is a preferential selfer, although some variations in selfing rate exist among individuals and between populations (Trouvé et al Cited by:. A group of 20 young and another of 20 adult Lymnaea truncatula were abundantly supplied with food and kept continuously under cold conditions (5°C) in the laboratory for 3 months and the effects of low temperature on their behaviour, growth and reproduction were studied.

The results indicate that at low temperature the activity of L. truncatula was markedly reduced but complete Cited by: 7.Les habitats de Lymnaea truncatula Müller (Mollusque) le long de deux rivières.
