总结
在温室试验中，拟除虫菊酯、溴氰菊酯单独使用或作为可消毒制剂使用，可阻碍健康植物感染持久性甜菜轻度黄化病毒（BMYV），以及烟蚜获得和感染非持久性马铃薯Y病毒（PVY）和半持久性甜菜黄化病毒（BYV）。
另一种拟除虫菊酯RU-15525也可防止PVY感染。即使是亚致死量的溴氰菊酯也会通过迅速使蚜虫失能来降低病毒传播，对于对有机磷杀虫剂和某些拟除虫菊酯（包括溴氰菊酯）最具抗性的蚜虫，这种影响最小。地美酮-S-甲基仅抑制BMYV的感染。这项工作表明，溴氰菊酯限制了温室中持久性、半持久性以及可能更重要的非持久性病毒的传播，并有可能在田间进行同样的工作。
SUMMARY
The pyrethroid, deltamethrin, alone or as an emulsifiable formulation, hindered infection of healthy plants with the persistent beet mild yellowing virus (BMYV) and both acquisition of, and infection with, the non-persistent potato virus Y (PVY) and the semi-persistent sugar beet yellows virus (BYV) by Myzus persicae in glasshouse tests.
Another pyrethroid, RU-15525, also protected against infection with PVY. Even sub-lethal amounts of deltamethrin decreased virus transmission by rapidly incapacitating the aphids, the effect being least with aphids most resistant to organophosphorous insecticides and to certain pyrethroids including deltamethrin. Demeton-S-methyl hindered infection only with BMYV. This work shows that deltamethrin restricts transmission of persistent, semi-persistent and perhaps more importantly of non-persistent viruses in the glasshouse, and has potential for doing the same in the field.
