【摘要】 为了探明蝇蛆寄生对家蚕免疫因子的影响,对家蚕追寄蝇(Exorista sorbillansW iedem ann)幼虫寄生的5龄家蚕血淋巴中血细胞数量的变化以及血淋巴酚氧化酶活性的变化进行了研究。结果表明:蝇蛆寄生家蚕后,家蚕血淋巴中颗粒细胞和浆细胞的数量急剧上升,在寄生后16~24 h,蝇蛆蚕血淋巴颗粒细胞和浆细胞数达到6.81×106/mL,比对照增加了4.76×106/mL;蝇蛆寄生导致血淋巴黑化反应加快,黑色素增加;蝇蛆蚕血淋巴酚氧化酶活性升高,在6 d内由7 U/mg上升到34 U/mg。更多还原

【Abstract】 The number of the cell and the activity of phenoloxidase in Bombyx mori parasitized by the larva of Exorista sorbillans Wiedemann was investigated.The results showed that the amount of the granular cell and plasmatocytes of the parasitized silkworm increased significantly.They were about 6.81×10⁶ /mL in 16²4 h after parasitized,increased by 4.76×10⁶ /mL compared to control.The melaninization of the haemolymph quickened and the melanin increased.At the same time,the activity of the phenoloxidase in haemolymoph increased from 7 U/mg to 34 U/mg in six days.更多还原
