蛞蝓是可耕种农业中的主要害虫，通常通过使用农药浸渍颗粒（杀软体动物剂）来控制。我们在2018年收到了农民的多次请求，要求研究蛞蝓颗粒对蚯蚓的影响，因为他们被告知铁基颗粒是“蠕虫友好的”。通过田间小区试验，比较了四聚乙醛（4%）和磷酸铁EDDS（3%）颗粒污泥的推荐产率，测定了蚯蚓（Lumbricus terrestrismiddens）对土壤动物的摄食活动。有一个显着的减少，在任何类型的蛞蝓球的存在下，特别是在顶部25毫米的土壤表明远离农药的运动的摄食活动。这可以解释为表土中蚯蚓的丰度（数量和生物量）明显较低。在施用磷酸铁基段塞颗粒后4个月，对照和处理地块之间的磷丰度没有显著差异，表明影响是暂时的。在实验室中，individualLumbricus terrestrisearthworms消耗多达4蛞蝓丸超过14天，生物量没有显着差异进行了测量。一项穴居适应性试验表明，蚯蚓暴露于磷酸铁基蛞蝓颗粒穴居到更深的深度。这表明了一种回避行为反应，这也可以解释现场结果。与农民（n= 68）进行的一次磋商将这一信息服务评为有用，并表明人们普遍关注尽量减少农药对非目标土壤动物的影响。
Slugs are a major pest in arable agriculture that are typically controlled by using pesticide‐impregnated pellets (molluscicides). We received multiple requests from farmers in 2018 for research into the impact of slug pellets on earthworms because they had been told that ferric‐based pellets were ‘worm‐friendly’. We measured soil fauna feeding activities withinLumbricus terrestrismiddens on a replicated field plot experiment comparing the recommended product rates of a metaldehyde (4%) based or ferric phosphate EDDS (3%) based slug pellets. There was a significant decrease in feeding activity in the presence of either type of slug pellet, particularly in the top 25 mm of the soil indicating movement away from the pesticide. This could be explained by the significantly lower abundance (numbers and biomass) of earthworms in the topsoil. Four months after ferric phosphate‐based slug pellet application, there was no significant difference between the control and treated plots in earthworm abundance, indicating the effects were temporary. In the laboratory, individualLumbricus terrestrisearthworms consumed up to 4 slug pellets over 14 days and no significant differences in biomass were measured. A burrowing fitness assay indicated that earthworms exposed to ferric phosphate‐based slug pellets burrowed to a greater depth. This suggests an avoidance behaviour response, which could also explain the field results. A consultation with farmers (n= 68) rated this information service as useful and indicated widespread interest in minimizing the effects of pesticides on non‐target soil fauna.
