Molluscicidal Activity of Methomyl and Cardenolide Extracts from Calotropis procera and Adenium arabicum Against the Land Snail Monacha cantiana

Abstract

, that is, the plant extracts were 9.24, 3.37, and 3.4 times more toxic than methomyl. In addition, a simple colorimetric method, based on Kedde reagent, was modified to determine cardenolide concentrations in plant extracts. Thin layer chromatography analysis (TLC) showed several cardiac glycosidal compounds in each plant extract. The results proved that cardiac glycosides are promising candidate compounds that could be used to control land snails, or exploited to develop new, effective, and environmentally friendly molluscicides.

Fumigant toxicity and antiacetylcholinesterase activity of Saudi Mentha longifolia and Lavandula dentata species against Callosobruchus maculatus (F.) (Coleoptera: Bruchidae)

“…Therefore, this work was carried out to examine the chemical composition of essential oils isolated from M. longifolia and L. dentata species grown in Saudi Arabia and to evaluate their fumigant toxicity and anticholinesterase activity against adult C. maculatus, to compare the composition of the two plant oils grown in other countries. This work is a continuation to our efforts to find promising, effective natural pesticides (Hussein et al, 1994(Hussein et al, , 1999Al-Rajhi et al, 2003;Hussein, 2005;Al-Sarar et al, 2012).…”

Molluscicidal activity of cardiac glycosides isolated from Adenium obesum

“…A remarkable molluscicidal activity of A. obesum benzene‐soluble fraction against the terrestrial snail M. obstructa was established in the present work with 20‐ and 8‐folds more potency than the conventional molluscicides, methiocarb and methomyl, respectively. Very few studies have reported the molluscicidal activity of Adenium , one of them on the benzene‐soluble fraction of A. arabicum against the terrestrial snail Monacha cantiana and the other on the methanol extract of A. obesum against the freshwater snail Bulinus truncatus , the intermediate host of Schistosoma haematobium . The molluscicidal activity of extracts containing cardiac glycosides was reported from different plant species such as Pergularia tomentosa , Calotropis procera , and Nerium indicum …”

Laboratory assessment of the molluscicidal and cercariacidal activities of Balanites aegyptiaca

“…Several plants, such as Phytolacca dodecandra (Endod), Solanum xanthocarpum, Annona squamosa, Thuja orientalis, Stryphnodendron polyphyllum, Calotropis procera and Adenium arabicum have already been identified as useful to control the intermediate hosts of trematodes [9][10][11][12][13][14] .…”
