| 摘 要： | 推广使用高效、安全的消毒药剂是规模化养蚕防病技术体系中的重要内容之一。将新型消毒药剂二溴海因配制成不同浓度药液,对家蚕真菌病、病毒病的主要病原体进行消毒试验。结果表明,以0.5g/L二溴海因药液进行蚕体消毒,可达到100%杀灭白僵菌、黄曲霉菌的消毒效果;单独使用二溴海因药液不能杀灭家蚕核型多角体病毒(BmNPV)、家蚕质型多角体病毒(BmCPV),但在质量浓度为0.5g/L的二溴海因药液中添加5.0g/L碳酸钠后,即可达到100%杀灭BmNPV、BmCPV的消毒效果,并且碳酸钠的添加不影响针对白僵菌、黄曲霉菌的蚕体消毒效果。二溴海因药液对家蚕的安全性试验表明,4～5龄期每天添食1次用1.0g/L(或0.5g/L)二溴海因+5.0g/L碳酸钠溶液浸润的桑叶,对家蚕的生长发育无明显影响,全茧量、茧层率等经济指标与对照相仿。综上初步认为,二溴海因和碳酸钠混合的消毒药液可以应用于家蚕真菌病、病毒病主要病原体的消毒。

| Abstract: | To popularize and use high effect and safe disinfectant is one of the important practices in disease prevention technological system for large scale silkworm rearing.In present study,different concentrations of a new disinfectant named dibromodimethvl hvdantoin were prepared and used to disinfect main pathogens of fungous and viral diseases in silkworm.The results indicated that,100% disinfection effect could be achieved against Beauveria bassiana and Aspergillus flavus with 0.5 g/L dibromodimethvl hvdantoin.The Bombyx mori nucleopolyhedrovirus (BmNPV) and cytoplasmic polyhedral virus (BmCPV) could not be perished if only dibromodimethvl hvdantoin was applied.However,after the dibromodimethvl hvdantoin solution with mass concentration of 0.5 g/L was added with 5.0 g/L sodium carbonate,100% disinfection effect could be achieved against BmNPV and BmCPV,while the addition of sodium carbonate had no adverse effect on the disinfection effect against B.bassiana and A.flavus.The results of safety test indicated that,growth and development of the 4th and 5th instar larvae feeding on mulberry leaves soaked with 1.0 g/L (or 0.5 g/L) dibromodimethvl hvdantoin and 5.0 g/L sodium carbonate once a day was not affected obviously,and the cocoon weight,cocoon shell rate and other economic indexes were about the same with those of the control.The above results suggest that the mixture disinfectant solution of dibromodimethvl hvdantoin and sodium carbonate can be used to disinfect main pathogens of fungous and viral diseases in silkworm rearing. |
