摘  要：
亚洲玉米螟幼虫血细胞包囊具双相性.当DEAE-sephadex珠子被诱导进亚洲玉米螟幼虫的血腔内后,颗粒细胞首先在3min内吸附到珠子表面,浆细胞随后吸附形成多层浆细胞层,注射48h后最终形成重叠细胞层的平滑囊鞘.完整的囊鞘显示有3层明显不同的区域.颗粒细胞起着最初识别血腔中的外源体作用,一旦珠子被颗粒细胞识别为外源体,颗粒细胞将裂解释放一些公认的物质诱导浆细胞识别外源体,于是包囊被立刻启动.总之,研究结果显示亚洲玉米螟幼虫包囊明显依赖血细胞之间的互相合作.

摘  要：
Encapsulation by haemocytes in Ostrinia furnacalis larvae was biphasic. When DEAE-Sephadex beads were introduced into the haemocoele of O. furnacalis larvae, granular cells first attached to the surface of the beads within 3 minutes, which was followed by the attachment of multiple layers of plasmatocytes, eventually forming a smooth capsule comprised of overlapping layers of cells until 48 h post injection. The complete capsule showed three distinct regions. The role of the initial identification of foreign bodies within the haemocoele was played by the granular cells. Once the beads were identified as foreign bodies by granular cells, some putative materials released by lysed granular cells would induce plasmatocytes to recognize the foreign bodies, and then encapsulation was immediately triggered. Collectively, these results suggested that encapsulation in O. furnacalis larvae obviously depends on a cooperative response between haemocytes.
