“…Close to our results, the LT 50 of a commercial product containing 5% metaldehyde tested against T. pisana was 2.84 days (68.16 h). 41 In comparison with other pesticides used in terrestrial mollusks control, the contact toxicity of metaldehyde (LD 50 = 11.33 μg g −1 ) is 17 times greater than that of the second mostly used molluscicide, methiocarb (LD 50 = 188.68 μg g −1 ). 42 The advantage of metaldehyde's high contact molluscicidal activity could be exploited in the application of this molluscicide in low concentration formulations (paints, pastes or sprays) on tree trunks or surfaces of glasshouses where snails climb on.…”

BACKGROUND: Terrestrial snails are one of the most damaging threats to sustainable agriculture. Chemical control using molluscicides is the main approach used to combat these agricultural pests. Metaldehyde is the active ingredient in most snail control products in use. However, its toxicity indices and mode of action have scarcely been investigated. For the first time, we characterized the metaldehyde contact toxicity indices against the white garden snail Theba pisana. The biochemical impact of metaldehyde on acetylcholinesterase (AChE), aspartate aminotransferase (AST) and alanine aminotransferase (ALT), alkaline phosphatase (ALP) and glutathione S-transferase (GST) activities and the lipid peroxidation (LPO) level was investigated.

Cigarette butts (CBs) contain a plethora of chemicals, including many that are toxic. Although numerous studies have demonstrated the toxicity of CBs to aquatic organisms, there is less evidence that terrestrial organisms are severely impacted. Because CBs are commonly discarded on the ground, ground-dwelling organisms such as land snails may be especially affected. Many land snails are generalist detritivores/herbivores and ingest a variety of plant secondary compounds as they feed. This evolutionary exposure may render CBs (made principally of cured tobacco leaves) less toxic to these land snails than CBs are to less exposed aquatic animals. We investigated this possibility of reduced effects using a new behavioural assay to test the choice of ‘flavoured’ vertical resting sites in the land snail Cornu aspersum, which commonly rests on upright surfaces. In four experiments, regions of container walls were coated with different concentrations of CB and cured tobacco effluents, and effluents from three tree species and cured tobacco. Snails avoided high CB and tobacco effluent concentrations, which is consistent with toxicity. However, snails preferentially rested on dilute concentrations of both CBs and tobacco. Preference among tree leaf effluents was less evident, with a trend towards snails preferring the more readily eaten maple than the less readily eaten oak. Selection of the preferred tobacco concentration did not differ from that of tree leaves, indicating that C. aspersum was not repelled by dilute tobacco effluent. These results indicate that compounds leaching from discarded CBs may have little effect on snails and perhaps other soil organisms under environmentally realistic conditions.

Background The negative effect of over-reliance on the use of synthetic pesticides have led to the search for natural alternatives to pest control. This study was designed to evaluate the toxicity effect of the crude plant extracts of Jatropha (Jatropha curcas Linn.) seeds in comparison with methomyl on some histopathological changes of the terrestrial snail species Monacha obstructa (Pfeiffer, 1842). The toxicity effect of methomyl and crude extracts of ethanol and acetone extracts of Jatropha curcas seeds were determined on some histological changes of the land snail, Monacha obstructa at four concentrations using the contact technique under laboratory conditions. Results The results revealed that the crude extracts of Jatropha exhibited obvious adequate effects compared with methomyl against M. obstructa land snails. The highest toxicity effects were obtained by methomyl followed by the ethanolic extract of Jatropha and hexane extract of Jatropha. The histopathological effect of LC50 of Jatropha crude extract and methomyl on the digestive gland and foot tissues were examined in the land snails M. obstructa. The treated snails showed several histological changes in the digestive gland and foot compared with the control group snails. The histological examinations of the digestive tubules included destroyed and detached in the outer layer covering digestive tubules. In addition, marked increase in the width most of the digestive tubules lumen. The intertubular connective tissue between the digestive tubules showed great destruction, while the foot of treated snails showed rupture of the epithelium covering the foot and desquamation of the epithelium. We also observed the presence of areas of connective tissue necrosis and destruction of the muscular tissue. Conclusions It has been found that extracts of Jatropha seeds have a toxic activity that caused histopathological damage that led to the death of land snails, and thus it can be recommended as a source for the development of molluscicides.
