地下害虫，如蚯蚓，可以通过它们的挖洞和抛掷活动来增加土壤养分的有效性。最近的一些研究探索了蚯蚓引起的这些变化是否会反过来影响植物的表现和对草食动物的抗性，但到目前为止还没有对这些文献进行正式的合成。
我们通过对截至2016年的现有文献进行荟萃分析，测试了蚯蚓对植物生长、对昆虫食草动物的抵抗力和化学防御的影响。我们还探索了可能解释不同研究之间蚯蚓对植物生长和抗性影响的大小差异的生态因素。
我们发现，蚯蚓的存在增加了植物生长(增加了20%)和氮含量(增加了11%)。总体而言，蚯蚓不影响植物对咀嚼食草动物(毛虫、鼻涕虫和根虫)的抵抗力，甚至导致植物对韧皮部食草动物(蚜虫)的抵抗力降低22%。然而，当植物受到细胞取食者(蓟马)的攻击时，蚯蚓的存在使化学防御的产生增加了31%，并导致对蓟马的抗性增加了81%。当接种的蚯蚓种类和生态类型混合时，以及蚯蚓密度较高时，蚯蚓效应的幅度更大。
这些结果表明，蚯蚓的存在是导致植物对食草动物防御能力自然变化的一个重要因素，并呼吁在植物-食草动物相互作用的研究中更好地整合土壤动物，无论是应用研究还是基础研究。

Subterranean detritivores such as earthworms can increase soil nutrient availability through their burrowing and casting activities. A number of recent studies have explored whether these changes caused by earthworms may in turn affect plant performance and resistance to herbivores, but no formal synthesis of this literature has been conducted to date.
We tested for the effects of earthworms on plant growth, resistance and chemical defences against insect herbivores by performing a meta-analysis of the existing literature up to 2016. We also explored ecological factors that might explain among-studies variation in the magnitude of the earthworm effects on plant growth and resistance.
We found that earthworm presence increases plant growth (by 20%) and nitrogen content (by 11%). Overall, earthworms did not affect plant resistance against chewing herbivores (caterpillars, slugs and rootworms), and even led to a 22% decrease in plant resistance against phloem-feeding herbivores (aphids). However, earthworm presence increased production of chemical defences by 31% when plants where attacked by cell-feeders (thrips), and resulted in an 81% increase in resistance against thrips. The magnitude of earthworm effects was stronger when earthworm inoculations consisted of a mix of species and ecological types, and when densities of earthworms were high.
These results suggest that earthworm presence is an important factor underlying natural variation in plant defences against herbivores, and call for a better integration of the soil fauna in the studies of plant-herbivore interaction, both for applied and fundamental research.
