GlyphosateN-（膦酰基甲基）甘氨酸是一种广泛用于农业的除草剂。蚯蚓以地表植物材料为食，这意味着该物种对农用化学品有独特的直接接触。在推荐的产品率，显着（F1，44= 8.67，p = 0.005）更高的数量L。在可耕地的草甘膦处理区域中发现了terrestrismiddens。实验室饲养试验，使用现场老化的植物材料表明，以前的草甘膦治疗是一个统计学上显着的因素，影响蚯蚓。陆生生物量（F1，12= 5.75，p =.03）。可检测到可忽略的草甘膦残留物，并且田间老化的植物材料被真菌菌丝覆盖。这表明草甘膦通过一种垃圾真菌复合体影响植物材料的定殖，从而改善蚯蚓的食物质量。在某些植物材料中检测到氟环唑（一种杀真菌剂）的浓度，可能会影响蚯蚓的整体食物质量。对新鲜志愿植物叶（不需要的作物幼苗）的草甘膦处理不是影响蚯蚓的统计学显著因素。陆生生物量（F1，6= 0.16，p = 0.92）。这些结果表明，真菌群落影响的摄食行为，和植物材料是一个直接来源的农用化学品的anecic蚯蚓。
GlyphosateN‐(phosphonomethyl) glycine is a widely‐used herbicide in agriculture. The anecic earthworm,Lumbricus terrestrisfeeds and forages for surface plant materials meaning that this species has a unique and direct exposure to agrichemicals. At the recommended product rates, significantly (F1,44= 8.67,p =.005) higher numbers ofL. terrestrismiddens were found in the glyphosate treated areas of an arable crop field. Laboratory feeding assays using field aged plant materials indicated that previous glyphosate treatment was a statistically significant factor affecting earthwormL. terrestrisbiomass (F1,12= 5.75,p =.03). Negligible glyphosate residues were detectable, and the field aged plant materials were encrusted with fungal hyphae. This suggests that glyphosate influences the colonisation of plant material by a litter‐fungus complex which improves the food quality to earthworms. Concentrations of epoxiconazole, a fungicide, were detected in some plant materials and may influence overall food quality to earthworms. Glyphosate treatment on fresh volunteer plant leaves (unwanted crop seedlings) was not a statistically significant factor affecting earthwormL. terrestrisbiomass (F1,6= 0.16,p =.92). These results indicate fungal communities influence feeding behaviours, and plant materials are a direct source of agrichemicals to anecic earthworms.
