is a hazardous snail that can damage ornamental plants and cause significant harm to plant sections in Egyptian areas. Herein, the molluscicidal activity of CuPb-Ferrite/TiO and TiO nanoparticles (NPs) against was evaluated using the poisonous bait method. LC50 values were determined using the leaf dipping and contact methods, with values of 631.23 and 1703.49 ppm for CuPb-Ferrite/TiO and 193.67 and 574.97 ppm for TiO. Exposure to both NPs resulted in a significant increase in the biochemical parameters of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP), as well as a decrease in total protein (TP) percentage of . Histological examinations revealed that many digestive cells had ruptured, and their contents had been lost, while the foot's epithelial layer became ruptured. The average reduction was 66.36% for CuPb-Ferrite/TiO NPs compared to the recommended molluscicide, Neomyl, with a 70.23% reduction in the field application. Electrophoretic separation of total protein using sodium dodecyl sulfate-polyacrylamide gel electrophoresis after treatment with LC50 concentrations of TiO and CuPb-Ferrite/TiO demonstrated the potency of these synthetic compounds as molluscicidal agents. Therefore, we recommend the use of CuPb-Ferrite/TiO NPs as a novel land snail molluscicide because it is safe to use, and the baits are arranged to not affect irrigation water, with a high molluscicidal effect.
是一种危害性蜗牛,能破坏观赏植物,并对埃及地区的植物造成严重损害。在此,采用有毒诱饵法评估了 CuPb-Ferrite/TiO 和 TiO 纳米粒子 (NPs) 对 的杀软体动物活性。采用叶浸法和接触法测定 LC50 值,CuPb-Ferrite/TiO 和 TiO 的 LC50 值分别为 631.23 和 1703.49 ppm,以及 193.67 和 574.97 ppm。暴露于两种 NPs 均会导致丙氨酸转氨酶 (ALT)、天冬氨酸转氨酶 (AST) 和碱性磷酸酶 (ALP) 的生化参数显著增加,同时 的总蛋白 (TP) 百分比降低。组织学检查显示,许多消化细胞破裂,内容物丢失,而足部的上皮层破裂。与推荐的杀软体动物剂 Neomyl 相比,CuPb-Ferrite/TiO NPs 的平均减少率为 66.36%,田间应用减少率为 70.23%。用 LC50 浓度处理后,用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳对总蛋白进行电泳分离,证明了这些合成化合物作为杀软体动物剂的效力。因此,我们建议使用 CuPb-Ferrite/TiO NPs 作为新型陆地蜗牛杀软体动物剂,因为它使用安全,诱饵布置不会影响灌溉用水,具有很高的杀软体动物效果。
