异杆线虫科和斯氏线虫科的昆虫病原线虫似乎能够进行长距离扩散和局部迁移。它们的传播策略包括高度活跃的寻找和摧毁行为和伏击策略，并且它们可能对自己种群中与性别相关的因素敏感。人们对它们寻找宿主的能力知之甚少，尽管这些能力对于它们作为土壤生物防治剂的成功至关重要。就像过去一个世纪为了生物防治而释放的大量外来膜翅目动物和其他天敌一样，它们可以以其具有生态能力的野生型形式使用。另一方面，由于它们被大量应用，因此可以通过育种或转化来定制它们，以达到其预期目的和生态无能性，从而提高其功效和生态安全性。
Entomopathogenic nematodes of the Heterorhabditidae and Steinernematidae appear to be capable of long-distance dispersal and local migration. Their transmission strategies include both highly active seek-and-destroy behaviours and ambusher strategies, and they may be sensitive to sex-related factors in their own populations. Their host-finding abilities are poorly understood, despite the fact that these abilities are fundamental to their success as biocontrol agents in soil. Like the vast numbers of exotic hymenopterans and other natural enemies that have been released for biological control over the past century, they may be used in their ecologically competent wild-type form. On the other hand, because they are applied inundatively they may be tailored, by breeding or transformation, to their intended purpose and to ecological incompetence, improving both their efficacy and their ecological safety.
