COMPARATIVE MOLLUSCICIDAL ACTIVITY OF ABAMECTIN AND METHOMYL AGAINST Eobania vermiculata (Müller) AND Theba pisana (Müller

Abstract

The molluscicidal activity of abamectin were assessed compared with methomyl against the most two abundant snail species brown garden snail (BGS) Eobania vermiculata and white garden snail (WGS) Theba pisana under laboratory conditions. The results indicated that LC50 values of methomyl were almost equal LC50 values of abamectin indicating more molluscicidal potency of abamectin and methomyl. Results also revealed a complete consistency of correlation between the LC50 values and exposed time intervals. The high molluscicidal activity of abamectin against E. vermiculata and T. pisana compared to methomyl using topical application technique could be used practically in the field of land snails control program and overcome some drawbacks of using bait forms in this respect. Comparing the LD50 values indicate the significant variation of the molluscicidal activity between the two applications methods used in addition to the variation between the two species of chosen snails, the brown garden snail E. vermiculata were resistant species than the white garden snail T. pisana.

Assessment of some new pesticides as molluscicides against the adult and eggs of chocolate banded snail, Eobania vermiculata

“…Although all tested pesticides considered insecticides, these pesticides used as molluscicides successfully. The previous studies confirmed that abamectin was more effective against the chocolate snail (Essawy et al 2009;Abdallah et al 2015;Hemmaid et al 2017). Using of imidacloprid and fipronil as ovicides was a very effective action against the hatchability of E. vermiculata eggs.…”

Comparative toxicity of abamectin and nano-derived form on land snail, Helix aspersa in attributing to cytotoxicity and biochemical alterations

“…There is an information of the toxic effects of ABM against land snails, where it had lethal toxic actions on the freshwater snails, Physa acuta [40], Biomphalaria alexandrina [41], land snails: Monacha contiana [42] and M. obstructa [43]. In addition, ABM was found to be more toxic on chocolate snail Eobania vermiculata [21,[44][45]. On the same species, assessment of pesticides: indoxacarb, ABM, and spiromesifen for 24 h obtained that, indoxacarb was the most toxic, followed by ABM and spiromesifen.…”

Avermectins: The promising solution to control plant parasitic nematodes

“…The avermectin B1 (Abamectin) proved its ability to manage different pests as an acaricide [16,21], insecticides [22], nematicide [10,23] and Molluscicide [24][25][26]. Meanwhile, abamectin was applied in many different methods such as soil treatment, seed treatment, injection in to plant stem and seedling root dip (Table 1) (Figure 1).…”
