植物寄生线虫（PPN）每年都对农业造成重大损害，这是一个迄今为止基本上未受阻碍的挑战。化学杀线虫剂已经以不同程度的成功使用，但是它们的实施可能是麻烦的，并且此外它们可能潜在地中和来自昆虫病原线虫（EPN）的另外的积极作用，所述昆虫病原线虫（EPN）与PPN在土壤环境中共存并且为植物提供针对昆虫害虫的保护。最近的研究已经探索了使用EPN保护植物免受PPN侵害的潜力，同时提供其标准程度的保护以对抗昆虫。所涉及的相互作用是非常复杂的，由于三种生物系统和土壤环境中存在的各种变量，但是在限制PPN感染性的背景下，已经积累了关于某些EPN及其互利共生细菌的抑制能力的强有力的证据。某些EPN复合物在昆虫感染过程中产生的特定因子似乎对PPN具有选择性杀线虫或至少排斥作用。利用这些信息，形成了一个机会，使这种关系适应大规模的田间条件，并可能减轻农业产业的最大负担之一。
Plant-parasitic nematodes (PPN) are responsible for substantial damages within the agriculture industry every year, which is a challenge that has thus far gone largely unimpeded. Chemical nematicides have been employed with varying degrees of success, but their implementation can be cumbersome, and furthermore they could potentially be neutralizing an otherwise positive effect from the entomopathogenic nematodes (EPN) that coexist with PPNs in soil environments and provide protection for plants against insect pests. Recent research has explored the potential of employing EPNs to protect plants from PPNs, while providing their standard degree of protection against insects. The interactions involved are highly complex, due to both the three-organism system and the assortment of variables present in a soil environment, but a strong collection of evidence has accumulated regarding the suppressive capacity of certain EPNs and their mutualistic bacteria, in the context of limiting the infectivity of PPNs. Specific factors produced by certain EPN complexes during the process of insect infection appear to have a selectively nematicidal, or at least repellant, effect on PPNs. Using this information, an opportunity has formed to adapt this relationship to large-scale, field conditions and potentially relieve the agricultural industry of one of its most substantial burdens.
