通过广东省廉江市龙营围对虾养殖场的现场试验 ,对 3种防治虾病的药物进行了比较研究 .结果显示 ,各处理组斑节对虾杆状病毒 (Penaeusmonodonbaculovirus ,MBV)感染率与用药前及对照组比较均无显著性差别 (P >0 0 5) .MBV感染度各处理组与用药前及对照组比较均有显著性差异 (P <0 0 5～P <0 0 0 1) .其中以 2号药物的作用较明显 ,但各处理组之间无显著性差别 (P >0 0 5) .对照组与用药前比较无显著性差别 (P >0 0 5) .研究表明 ,3种药物均能降低MBV的感染度 ,起到预防MBV病发作的作用 .鉴于 2号药物价格较昂贵 ,而 1号药物和维生素C则药源丰富 ,价格便宜 ,其作用和 2号药物无显著性差别 ,故主张 1号药物和维生素C合用 ,作为预防MBV病发作的首选药 .
Through the field test of shrimp farms in Longyingwein, Lianjiang City, Guangdong Province, three kinds of drugs for preventing and treating shrimp diseases were compared and the results showed that the infection rate and the rate of infection of Penaeus monodon baculovirus (MBV) There was no significant difference between the pre-treatment and control groups (P> 0.05), and there was significant difference in the infection rate of MBV between the treatment groups and before treatment and the control group (P <0.05 ~ P <0.01) The effect of No.2 drug was obvious, but there was no significant difference among the treatment groups (P> 0.05) .The control group had no significant difference compared with that before treatment (P> 0.05) 3 kinds of drugs can reduce the degree of MBV infection play a role in preventing the onset of MBV .In view of No. 2 drug prices more expensive, and No. 1 drugs and vitamin C is rich in drug sources, the price is cheap, its role and No. 2 drug Significant difference, it advocates No. 1 drug and vitamin C co-use, as the first choice to prevent the onset of MBV disease.
