The Japanese invasive jumping snail Ovachlamys fulgens is a pest of ornamental plants and an intermediate host nematode that causes eosinophilic meningitis. We expand its distribution to eight municipalities from Rio de Janeiro State, one locality the Paraná generated for first time partial sequences cytochrome c oxidase subunit I (COI) gene Brazilian populations. External morphology, reproduct...

Use of molluscicides in the attractant food pellet (AFP) is an effective method of snail control. Different concentrations of these molluscicides viz. Azadirachta indica bark powder, Allium sativum bulb powder, Polianthes tuberosa bulb powder, Annona squamosa seed powder, their active components azadirachtin, allicin, hecogenin, acetogenin; herbal molluscicide pestoban and a synthetic m...

It is aimed to determine the positive and quality of Sea Snail (Rapana venosa) process. The samples examined in research are determined after introduction (Rapanoza) boiling, washing, selection snail meat content shell, temperature, 24 final freezing at -35 -40C whether will be passed through glass-18zene before suffocating from shock. After a week, total six stage were stored freezer – 80 °C. ...

This analysis studied the effects modification on properties of starch-based polymer grafted with acrylonitrile (copolymers). Starch was extracted from bitter yam. The starch modified by heating solution above 70 °C and then esterified phthalic anhydride to produce a pregelatinized phthalated derivative. Acrylonitrile onto natural at 120 using calcium oxide snail shell as initiator. grafting re...

this guide to the identification of iranian freshwater snails has been prepared with aim of helping individuals involved in field work, but who have had no specialized training in taxonomy to differentiate snail specimens which they collect to certain groups by means of simple identification key. the guide pays special attention to the principal snail groups which transmit human schistosomiasis...

Terrestrial gastropod molluscs (slugs and snails) (Mollusca: Gastropoda) cause significant crop damage around the world. There is no formal approach for differentiating between slugs snails; however, an organism usually considered a slug when there external shell, or shell small in comparison to body, snail large shell. Although snails are important pest of many crops, this review focuses on pe...

Serotonergic systems play important roles in modulating stress-induced arousal and vigilance behaviours. The pond snail, Lymnaea, shows multiple defensive vigilance behaviours in response to the stress associated with predator detection. Predator detection elicited by crayfish effluent (CE), increases the time to re-emerge from the shell and enhances the shadow withdrawal response. More importa...
