Toxicity of Commiphora Molmol (myrrh) Water Suspension to Some Non-target Aquatic Organisms and Its Molluscicidal and Biological Activities on Bulinus Truncatus and Biomphalaria Alexandrina (mollusca, Gastropoda)
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...
متن کاملMolluscicidal Effects of Talinum triangulare on Bulinus truncatus
The molluscicidal effects of Talinum triangulare from two locations in Nigeria on Bulinus truncatus were studied in the laboratory. Snails were exposed for 96h to different concentrations of ethanolic extract of the plant root from Nsukka in Enugu State and Erei in Cross River State, Nigeria. Those in dechlorinated water served as control. On coming in contact with the test medium, the snails r...
متن کاملPhytotoxic and Insecticidal Activity of Plants of Family Zygophyllaceae and Euphorbiaceae
The statistical analysis revealed that 10g and 20g extracts of all the tested plants significantly inhibited the growth of Lemna minor with significant differences. The plants means were non-significant while the interaction between extracts and plants was significant. Fagonia cretica, Peganum harmala, Tribulus terrestris, Chrozophora tinctoria and Ricinus communis caused significant growth inh...
متن کاملstudies on the biology of bulinus truncatus under laboratory conditions
a two-year laboratory study on the biology (including self-fertilization) of bulinus truncatus, the intermediate host of schistosoma haematobium, s. bovis and paramphistomum microbotrium in iran, has revealed information on the longevity, reproduction, hatchability rate, hatching time during various months of the year, and growth and mortality rates of this snail. it was found that the reproduc...
متن کاملThe genetical and environmental determination of phally polymorphism in the freshwater snail Bulinus truncatus.
In some species of self-fertile pulmonate snails, two sexual morphs co-occur in natural populations: regular individuals and aphallic individuals that cannot transmit sperm to other snails. Purely aphallic populations therefore reproduce obligatorily by selfing. Understanding the evolution of aphally and selfing in these snails requires a precise knowledge of phally determination. In this paper...
