The molluscicidal activity of Commiphora molmol (myrrh) water suspension showed that Bulinus truncatus snails were found to be about 3 times more susceptible than Biomphalaria alexandrina snails. The 24-hour LC50 values recorded were 46.4 and 145.8 ppm, respectively. There was a significant negative correlation between LC values and exposure periods. The present study is yet the first attempt t...

Wolves, foxes, birds, caterpillars, and snails are animals, and there are some of each of them. Also there are some grains, and grains are plants. Every animal either likes to eat all plants or all animals much smaller than itself that like to eat some plants. Gaterpillars and snails are much smaller than birds, which are much:' smaller than foxes, which in turn are much smaller than wolves. Wo...

molluscicidal activity of different organic solvent extracts of latex of euphorbia pulcherima and euphorbia hirta (family-euphorbiaceae) against two freshwater harmful snails lymnaea acuminata and indoplanorbis exustus has been reported. both the snails are the intermediate hosts of fasciola hepatica and fasciola gigantica, which cause endemic fascioliasis in cattle and livestock of eastern par...

background: freshwater pulmonate family lymnaeidae are well-known for their role in transmission of diginean trematodes worldwide. objectives: the study was aimed to investigate the ecology and effects of physical and chemical components of the environment on their distribution and populaion density. methods: the lymnaeid snails were randomly collected from 16 freshwater habitats in west azarba...

The trematode Microphallus sp. alters the behavior of its snail intermediate host, Potamopyrgus antipodarum, in ways that seem to increase transmission to its final host, e.g., waterfowl, and decrease the probability of being eaten by other predators, e.g., fish. The parasite seems to cause the snail to move from the top to the bottom of rocks at about 0900 hr. Waterfowl feed predominantly befo...

Individual infections of Egyptian and French Pseudosuccinea columella with five miracidia of Calicophoron daubneyi were carried out to determine whether this lymnaeid was capable of sustaining larval development of this parasite. On day 42 post-exposure (at 23 °C), infected snails were only noted in groups of individuals measuring 1 or 2 mm in height at miracidial exposure. Snail survival in th...

The uptake and effects (survival, weight) of copper (Cu) on Florida apple snails (Pomacea paludosa) via exposures to copper-enriched agricultural soil-water and water-only treatments were investigated. Soils were collected from citrus sites in south Florida and flooded with laboratory freshwater for 14d. Neonate apple snails (96-h-old) were then exposed to either Cu from a soil-overlying water ...

BACKGROUND Fasciolosis in livestock is a crucial concern in the globe, mainly due to its impact on human health. The aim of this study was to determine the rate of infection with Fasciola gigantica (Cobbold, 1855) larvae in the field-collected snails of Lymnaea auricularia (Linnaeus, 1785) from northwestern Iran using a molecular approach. METHODS A total of 6,759 pond snails were collected f...

In schistosomiasis, the host/parasite interaction remains not completely understood. Many questions related to the susceptibility of snails to infection by respective trematode still remain unanswered. The control of schistosomiasis requires a good understanding of the host/parasite association. In this work, the susceptibility/resistance to Schistosoma mansoni infection within Biomphalaria ale...
