In insects, bacterial endosymbionts are known to influence the ecology of their hosts by modifying interactions with natural enemies such as parasitoids. Symbionts can modulate both parasitoid behavioral and/or physiological traits as well as host behaviors and life-history traits. Together these suggest that endosymbionts may impact the host range of parasitoids. For example, endosymbionts may narrow parasitoid host range through first, reducing parasitoid ability to locate hosts and/or larval survival, second, affecting fitness traits of the emerging adult parasitoid and/or third, modulating the outcome of interference and exploitative competition between parasitoid species. From both a fundamental and applied point of view, these symbiotic effects would influence the ecology and evolution of parasitoids and associated population-level processes and ecosystem services (e.g. biocontrol).
在昆虫中，细菌内共生体通过改变与寄生蜂等自然天敌的相互作用，从而影响宿主的生态。共生体可以调节寄生蜂的行为和/或生理特征以及宿主的行为和生活史特征。所有这些都表明，内共生体可能会影响寄生蜂的宿主范围。例如，内共生体可以通过以下几种方式来缩小寄生蜂的宿主范围：首先，降低寄生蜂寻找宿主和/或幼虫生存的能力；其次，影响即将出现的成年寄生蜂的适合度特征；最后，调节寄生蜂种间干扰和掠夺性竞争的结果。从基础和应用的角度来看，这些共生效应将影响寄生蜂及其相关种群水平过程和生态系统服务（例如生物防治）的生态学和进化。
