The concentration of a pesticide used in agriculture not only has implications for effectiveness of pest control but may also have significant wider environmental consequences. This research explores the acceptability of metaldehyde slug pellets at different concentrations by (Müller, 1774) (Agriolimacidae), and the changes in the health status of the slug when allowed to recover. The highest metaldehyde concentration (5%) yielded the highest slug mortality; however, it also produced the highest proportion of unpoisoned slugs, suggesting the highest level of pellet rejection. Pellets with 1% metaldehyde were as effective as 3% pellets in paralysing a significant proportion of the population after initial pellet exposure; however, more slugs were able to recover from metaldehyde poisoning at 1% metaldehyde compared with 3%. There was no statistically significant difference between the mortality rate of slugs regardless of metaldehyde concentration, suggesting that a lower concentration of metaldehyde may be as effective as a higher concentration.
农业中使用的杀虫剂浓度不仅对害虫防治效果有影响，还可能产生更广泛的重大环境后果。本研究探讨了不同浓度的聚乙醛蛞蝓颗粒剂对（穆勒，1774年）（嗜黏液蛞蝓科）的可接受性，以及蛞蝓在恢复时健康状况的变化。最高的聚乙醛浓度（5%）导致了最高的蛞蝓死亡率；然而，它也产生了最高比例的未中毒蛞蝓，表明颗粒剂的拒食率最高。初始接触颗粒剂后，含1%聚乙醛的颗粒剂在麻痹相当比例的蛞蝓方面与含3%聚乙醛的颗粒剂效果相同；然而，与3%的浓度相比，1%聚乙醛浓度下更多的蛞蝓能够从聚乙醛中毒中恢复。无论聚乙醛浓度如何，蛞蝓的死亡率之间没有统计学上的显著差异，这表明较低浓度的聚乙醛可能与较高浓度一样有效。
