In Vitro Assessment of The Efficacy of Metaldehyde, Methomyl and Copper Sulfate on some Terrestrial Gastropods. التقييم المعملى لفعالية الميتالديهيد والميثوميل وکبريتات النحاس على بعض البطنقدميات الأرضية

Land mollusks are significant an economical pest invading diver’s flora in Egypt. In the light of this trial, Evaluated efficiency chemical compounds as metaldehyde, methomyl and copper sulfate against two land snail’s species chocolate-band snail, Eobania vermiculata glassy clover Monacha obstructa related to families, Helicidae Hygromiidae was inquired. The findings showed that metaldehyde most lethal complex M. E. came after through seven days that, values concentrations 50 were (1.03, 1.80 19.70 %) (1.60, 9.18 89.38%), respectively. Furthermore, more sensitive methomyl, including compared brown garden snail. So, caused % mortality, for clover, (96, 96 84 respectively, whereas percentage mortalities snail (96.48, 76 71.42%) sulfate, Moreover, there is not dissimilarity sensitivity between examined snails methomyl. Additionally, mortality increasing by time exposure compounds. This investigation displayed, can use a molluscicide at concentration 20 × 103 ppm, give range (55.17 – 96.0) %.
