由膜翅目内寄生蜂Cotesia rubecula产生的多核糖核酸病毒与卵一起沉积到鳞翅目寄主菜粉蝶体内，显然参与了对寄主防御系统的抑制。寄生后约6h，宿主血细胞的表面性质、肌动蛋白细胞骨架结构和黏附性质发生改变。在这里，我们显示了一个多聚核糖核酸病毒基因在毛虫血细胞内以一种瞬时的方式在寄生后4到8小时内表达。
Polydnaviruses produced by the hymenopteran endoparasitoid Cotesia rubecula are deposited together with the egg into the lepidopteran host Pieris rapae and are apparently involved in the suppression of the host's defence system. Around 6 h post-parasitization host haemocytes change their surface properties, actin cytoskeleton structure and adhesion properties. Here we show that a single polydnavirus gene is expressed inside the caterpillar haemocytes in a transient fashion between 4 to 8 h post-parasitization.
