新型蚕用消毒剂“防消灵”对家蚕病毒多角体及微粒子的消毒效果和机理

Disinfect Effect and Mechanism of Fangxiaolin, A New Disinfectant for Silkworm Rearing, on Polyhedron Viruses and Prbrine Sporozoa

“防消灵”是四川省蚕研所复配的新型、广谱、高效、安全、无腐蚀性及化学性能稳定的液粉兼用消毒剂。本试验以含１％有效氯漂白粉药物作对照，用“防消灵”对家蚕微粒子孢子虫、家蚕病毒多角体消毒，经口接种添食家蚕的方法对防消灵作了试验。结果表明，其消毒防病效果达９８％～９９．７％，经用电镜扫描观察，病原物出现变形、粘连、裂孔、药物内渗、溶解和形态结构破坏而灭活。经农村小试、中试，其消毒防治效果与漂白粉对照比较相当或略佳。

Fangxiaolin is a new disinfectant prepared by Sericulture Institute,Sichuan Academy of Agricultural Sciences and characterized by high efficiency,broad spectrum and stable chemical property.After pebrine sporozoa(N.b)and polyhedron viruses(BmCPB and BmNPB) were treated with Fangxiaolin,and then inoculated per os to the silkworms,it was found that the control efficiency of this agent was 98%-99 7%.Scanning electron microscope observation showed that the pathogens showed deformity,adhesion, perforation,dissolution and distroyed morphological structure,finally inactivation.Rural trials and regional trials showed that the control effect of Fangxiaolin was equal to that of bleaching powder,even better.
