植物如何应对食草动物的攻击部分受到植物生存的生物和非生物环境的调节。例如，理论预测土壤肥力应该驱动植物资源分配模式和防御策略。蚯蚓通过其挖洞和铸造活动改变土壤理化性质和土壤肥力。因此，蚯蚓介导的土壤性质变化可能会改变植物生理、植物营养质量，并最终改变植物对食草昆虫的抵抗力。我们通过测量两种蚯蚓（一种是表内生蚯蚓（Amynthascorticis）和一种内生蚯蚓（Metaphire guillelmi））对土壤性质、番茄植株生理性状和植物对西花蓟马（Frankliniella occidentalis）的抗性的组合效应来检验这一假设。我们发现A.皮质单独比 M 更能增加植物抗性。吉列米单独或两个物种的组合。植物抗性的增强与防御相关植物激素茉莉酸和酚类化合物产量的显着增加有关。此外，我们观察到蚯蚓介导的土壤性质变化与植物生态生理特性之间存在密切联系。因此，我们的结果建立了一个更好的预测模型，说明蚯蚓如何同时影响土壤参数、植物生产力和对草食害虫的抵抗力。
How plants cope with herbivore attack is partially modulated by the biotic and abiotic environment where the plant lives. For instance, theory predicts that soil fertility should drive patterns of plant resource allocation and defensive strategies. Earthworms, by their burrowing and casting activities, modify soil physicochemical properties and soil fertility. Therefore, earthworm-mediated changes in soil properties could alter plant physiology, plant nutritional quality, and ultimately, plant resistance against insect herbivores. We tested this hypothesis by measuring the combinatorial effects of two earthworm species, an epi-endogeic earthworm (Amynthascorticis) and an endo-anecic earthworm (Metaphire guillelmi), on soil properties, tomato plants’ physiological traits and plant resistance against the western flower thrips (Frankliniella occidentalis). We found thatA. corticisalone increased plant resistance more thanM. guillelmialone or the combination of two species. The increased plant resistance was associated with a significant increase in the defence-related phytohormone jasmonic acid and the production of phenolic compounds. Furthermore, we observed a strong link between earthworm-mediated changes in soil properties and plant eco-physiological traits. Our results thus build toward a better predictive model of how earthworms can simultaneously influence soil parameters, plant productivity and resistance against herbivore pests.
