| Abstract | ||
| This study was conducted to evaluate the toxicity of methomyl and lambda insecticides on the terrestrial snail, Monacha cartusiana. The two techniques are contact and leaf dipping techniques. The findings showed that the methomyl was more harmful to snails than lambda in both modalities. The contact method resulted in a higher fatality rate than the dipping method. The LC50for methomyl and lambda on snails was (1.31 and 1.45%) /100ml, with mortality percent 93.2% after 24 hours using the contact technique. The LC50 of methomyl and lambda were 2.50 and 13.87 %/100ml on the second day, and 1.89 and 10.72 %/100ml on the sixth day, with mean death rates of 80.0±3.85% and 25.0±2.35%, respectively. It could be concluded that the contact technique was more effective against the terrestrial snail, Monacha cartusiana than the dipping technique. Moreover, methomyl was more toxic than lambda as a molluscicide for both techniques | ||
