昆虫宿主可以利用包囊现象在寄生蜂感染后存活。在黑腹果蝇中，将黄蜂种类Leptopilina boulardi和Asobara tabida包裹起来的能力各自涉及一个主要基因。这两种抗性基因都精确地定位在第二条染色体上，相距35厘摩。这一结果清楚地表明，至少有两个独立的遗传系统参与果蝇抗寄生蜂。对L. boulardi和A.与迄今为止克隆的许多植物对病原体的抗性基因相反，虻不成簇。
Insect hosts can survive infection by parasitoids using the encapsulation phenomenon. In Drosophila melanogaster the abilities to encapsulate the wasp species Leptopilina boulardi and Asobara tabida each involve one major gene. Both resistance genes have been precisely localized on the second chromosome, 35 centimorgans apart. This result clearly demonstrates the involvement of at least two separate genetic systems in Drosophila resistance to parasitoid wasps. The resistance genes to L. boulardi and A. tabida are not clustered as opposed to many plant resistance genes to pathogens cloned to date.
