1. The number of natural enemies that should be introduced to control a pest is a controversial subject in biocontrol. A previous semi‐mechanistic model parameterised using a laboratory system consisting of two parasitoid wasps, Anisopteromalus calandrae and Heterospilus prosopidis, parasitising a pest beetle, Callosobruchus chinensis, indicated that the introduction of the non‐native parasitoid H. prosopidis decreases the level of intraspecific interference between native A. calandrae females. The model also suggested that this decrease was the main factor destabilising the population dynamics of the host–parasitoid system, resulting in chaos.

由非本地寄生物修饰的本地寄生物之间的种内干扰及其对种群动态的影响

1. 应引入多少天敌来防治害虫是生物防治中一个有争议的话题。之前的半机械模型使用实验室系统参数化，该系统由两种寄生蜂 Anisopteromalus calandrae 和 Heterospilus prosopidis 组成，寄生害虫甲虫 Callosobruchus chinensis，表明引入非本地寄生蜂 H. prosopidis 降低了种内干扰水平在本地 A. calandrae 雌性之间。该模型还表明，这种减少是破坏寄主-寄生蜂系统种群动态稳定的主要因素，导致混乱。
