“…The impeding of breeding of animals during winter period was not broken even by a 3-week acclimation at a temperature of 19°C and natural photoperiod, which is in accordance with the observations of other authors (Maat et al, 1982;Goldman, 2001). Jigyasu and Singh (2010) argued that the primary factor deciding the initiation of reproductive activity is not a temperature but the proper photoperiod. At the acclimation temperature snails fed few and moved little, which was a further difference with individuals tested in the May-September period ( _ Zbikowska and Cichy, 2011) and could affect their lowered thermal preference.…”

“…42 Embryological development is highly influenced by the change of ecological factors in aquatic environment. 9 Ranjan 43 stated that breeding season and the incubation period vary with the nature of the environment. Raut 44 concluded that the rate of breeding in the number of snail's viz., Lymnaea acuminata, Indoplanorbis exustus and Acrostoma variabilis were governed by temperature, rainfall and food.…”

“…Abiotic factors increases the rate of reproductive capacity. 9 Srivastava et al 10 reported significant positive correlation between acetyl cholinesterase and egg laying in Lymnaea acuminata a fresh water pulmonates. The aim of the present review is demonstrate the role CDCs cells, their structure and mechanism involve in reproduction behavior of pulmonates.…”

The gastropods are commonly known as snails and slugs. They are a large taxonomic class within the phylum Mollusca. The cerebral neurosecretory caudodorsal cells (CDCS) of the fresh water pulmonate Lymnaea control egg laying, an event that involves a pattern of stereotyped behavior. The CDCS synthesize and release multiple peptides, among which is the ovulation hormone (CDCS). It is thought that each peptide controls a specific aspect of the processes involved in egg laying. Dopamine is commonly found in the molluscan central nervous system (CNS). In some gastropods, dopamine has been implicated in the regulation of egg laying behavior that stimulates protein secretion from albumen gland. The albumen gland in pulmonate snails is an accessory gland of the female reproductive tract. It synthesizes and secretes perivitelline fluid (PVF), which is composed mainly of proteins and polysaccharides.

“…It is regarded as a rapid and efficient method of reducing or eliminating transmission, as well as breaking up the parasite life cycle ( MELLO-SILVA et al . 2006 , JIGYASU & SING 2010 ). The search for local molluscicidal plants was considered more sustainable than the use of synthetic drugs (HAMMAMI et al .…”

Fasciolosis is a widespread parasitosis of farm live-stock in many developing countries. For this reason, it is necessary to search for new substances against parasitic diseases caused by flukes. Indeed, a wide variety of terrestrial plants have been subjected to chemical and pharmacological screening in order to discover their potential for human medicinal use. The molluscicidal and larvicidal activities of Atriplex inflata were tested on Galba truncatula and Fasciola hepatica larval stages infecting this snail in Tunisia. Phytochemical tests were conducted on extracts in order to establish a meaningful relationship with molluscicidal and larvicidal activities. The molluscicidal activity was evaluated by subjecting snails to sample aqueous solutions. Accordingly, hexane, ethyl acetate, methanol and methanol-water (8:2, v-v) were used as extraction solvents. As a result, hexane and ethyl acetate extracts showed potent activity, according to the World Health Organization, giving LC50 = 7.59 mg/L and 6.69 mg/L for hexane extracts of leaves and fruits, respectively. Ethyl acetate extracts gave LC50 = 5.90 mg/L and 7.32 mg/L for leaves and fruits, successively. Molluscicidal activities of powders were less potent on snails, but active according to the World Health Organization. Hexane and ethyl acetate extracts from leaves and fruits gave potent larvicidal activities with a delay rate exceeding 45.50% (45.50- 98.92%). Phytochemical tests showed that these activities may be attributed to the presence of triterpenoids and/or sterols.
