“…In the present study, it is evident that the contact method is more effective than the dipping leaf method. This finding aligns with the observations of Abdel-Kader et al (2007), who investigated the efficacy of C. procera extract against two land snails, Monacha cartusiana and Theba pisana. The results indicated that the application of certain plant water extracts through spraying techniques was more efficient against land snails compared to incorporating the extracts into lettuce leaves as poisonous food or using the ground plant parts directly.…”

Ethanolic extracts of fresh Osher, Calotropis procera and Daflla, Nerium oleander leaves were assessed in vitro for their molluscicidal activity against the glassy clover snail, Monacha obstructa (Pfeiffer). The evaluation involved both contact and leaf dipping techniques over a 72 hrs. period. Additionally, combinations of each plant extract with methomyl as a chemical pesticide, were tested at a 1:1 ratio (v/v) in order to mitigate the harmful effects of methomyl while maintaining its high molluscicidal activity. Results demonstrated high toxicity of the plant extracts against the target snails, with the contact technique exhibiting greater efficacy than the dipping leaf method for both plant extracts and methomyl. The LC 25 and LC 50 values of C. procera via contact and leaf dipping methods were found to be (8.24 and 13.86) and ( 27.09 and 36.02) ppm, respectively. Similarly, sub-lethal concentrations of N. oleander achieved via the contact method were (12.55 and 19.84) ppm for LC 25 and LC 50 , respectively, while the leaf dipping application yielded LC 25 and LC 50 values of (20.83 and 29.25) ppm, respectively. Methomyl exhibited LC 25 and LC 50 values of (7.68 and 12.88) ppm via the contact method and (27.13 and 37.89) ppm for the leaf dipping method. Furthermore, mixing methomyl with either N. oleander or C. procera extracts resulted in varying rates of mortality among the tested snails, with different combinations leading to different mortality rates over specific time intervals.

“…In addition, using water extracts of Neem, Nerium, Apple of Sodom, and Red Squill as a spraying technique was more efficient against Carthusian and white garden snails than lettuce leaves as toxic meals or utilizing ground plant components directly (Abdel Kader et al, 2007). Our study indicated that aqueous extracts for Nerium (flowers and leaves) were enrolled with moderate percentage mortality which was (58.06 and 56.96%) respectively.…”

Land snails (Monacha obstructa) are commonly found in a variety of plant species, making them an important target for this study. Therefore, the opjective of this study is to compare eleven plant extracts and select the most efficient one to evaluate the acute toxicity of their extracts using the contact method against Monacha obstructa. The findings revealed that the plant extracts with the highest effectiveness against land snails were chinaberry (Melia azedarach), apple of Sodom (Calotropis procera), Nerium (Nerium oleander), and Basil (Ocimum basilicum) leaf extract. Consequently, the results indicated that the aqueous extracts from the leaves of M. azedarach exhibited high toxicity, with an LC50 value of 11.88 mg/L and a 100% mortality rate. Following that, C. procera leaves had an LC50 value of 16.82 mg/L and a mortality rate of 70.61%. The aqueous extracts from N. oleander (flowers and leaves) displayed a moderate mortality rate of 58.06% and 56.96% with LC50 values of 20.46 mg/L and 20.85 mg/L, respectively. The decoction of the leaves of the plants with O. basilicum leaf extract had the lowest death rate for individuals after 24 h which was 45.90%, and the toxicity rate for land snails was recorded at 25.88 mg/L. However, the rate of death of treated snails were decreased compared to that of control ones. These findings suggest the potential recommendation of utilizing a decoction of the extracted plants as an alternative to expensive and environmentally harmful pesticides for controlling clover snails.

“…These differences in toxicity levels may have been due to various classes of compounds responsible for molluscicidal activities of plants. Abdel Kader et al (2007) found that using some plant water extracts with spraying was more efficient against land snails Monacha car tusiana (Müller) and Theba pisana (Müller) than using poisonous foods or grinding plant parts. Also, Ali et al (2013) studied the use of the aqueous extract of Sola num nigrum as a molluscicide to control the brown garden snail, Eobania vermiculata (Müller) under laboratory conditions.…”

As it is known that the excessive use of pesticides causes many environmental problems, the effects of four aqueous plant extracts and their powders [Solanum nigrum L., Withania somnifera (L.) Dunal, Salix mucronata Thunb. and Lawsonia inermis L.] were evaluated as natural molluscicides on the land snail Monacha obstructa (Family: Hygromiidae) under laboratory conditions. Three different bioassay methods were used: contact, leaf-dipping and bait techniques. The results indicated that, using all methods, S. Nigrum extract was the most toxic extract for the terrestrial snail M. obstructa. The contact technique of the tested plant extracts was the most effective method of application compared to other methods. Moreover, using plant extracts was better than using powders of these plants for controlling the terrestrial snail M. obstructa. In addition, the results indicated that the aqueous extract of S. nigrum gave the highest percentage of reduction in the snail population when assessed under field conditions. The obtained data showed that plant extracts were significantly effective against the terrestrial snail and could be used as alternatives to pesticides in integrated pest management.
