摘要/Abstract

摘要： 通过对虾的室内人工感染和野外群体感染,建立了对虾暴发性流行病的群体感染模型,分析了投饲蝇幼的抗病机制.结果表明,合理投饲蝇蛆的对虾,50%死亡时间较对照组延迟3～5倍;病毒感染对虾7～10d前投喂蝇幼,蝇幼激活了对虾酚氧化酶系统,酚氧化酶活力较对照组提高约3倍;对虾群体感染模型的建立,直观地说明了蝇幼在提高对虾抗杆状病毒感染过程中发挥的重要作用.

Abstract: Based on indoors individual infection and outdoor population infection of shrimp, population infection model was established and anti-baculovirus mechanism of housefly larvae was analyzed. The results showed that 50% death time of the shrimps feeding with housefly larval reasonably was prolonged 3～5 times compared with the control group. Prophenoloxidase system of prawns was activited while feeding shrimps with housefly larval 7～10 days before infection by baculovirus, and prophenoloxidase activity was 3 times higher than the control group. The establishment of population infection model illustrated clearly important role of housefly larvae in improving the immunity of shrimps from baculovirus.
