| Abstract | ||
| The effect of three types of soil — clay, sand, and a mixture of clay/sand (1:1) — on the biological aspects of the brown garden snail Eobania vermiculata and the molluscicidal action of four different pesticides on the tested snails were investigated. Sand soils produced the largest numbers of clutches, eggs per clutch, and egg grooves with the greatest depth, whereas it gave the smallest egg diameter compared to the other two soils. There were no significant differences among the three soils except in the number of eggs per clutch between sand and clay soils. The growth rate of shell diameter increased with age (from two to six months) similarly across all soil types, with no significant differences. On the other hand, oxamyl and methomyl proved to have strong molluscicidal effects against E. vermiculata with LC₅₀ values of 0.6 and 0.7%, respectively, whereas glyphosate and carbofuran showed moderate effects with LC₅₀ values of 1.1 and 1.28%, respectively. | ||
