应用酶联免疫吸附技术和生物检测技术,在江苏省各地的蚕豆田调查并测定了19科66种植物的可疑病株,证实蚕豆萎蔫病毒于自然条件下,在秋、冬季可侵染蚕、豌豆,菠菜和小青菜等而越冬;在夏季则可侵染反枝苋,苍耳,大豆,灰藜和苋色藜等双子叶植物而越夏,从而完成其侵染循环。组建了BBWV在江苏省的侵染流行模式图。小青菜和反枝苋等作为BBWV的自然寄主在国内属首次发现。利用除虫菊酯和矿物油来治蚜防病,不仅效果好,还有促进生长和增产的效应。
Application of enzyme-linked immunosorbent assay (ELISA) and bioassay technology, we investigated and determined the suspicious strains of 19 families and 66 species in the faba bean field in Jiangsu Province. The results showed that the Vicia faba virus could infect the silkworm in autumn and winter under natural conditions, Peas, spinach and small green vegetables and overwintering; in the summer can be infected with Amaranthus retroflexus, Xanthium, soybean, quinoa and amaranth and other dicotyledons and summer, so as to complete its infection cycle. Set up a BBWV epidemic pattern in Jiangsu Province. Small cabbage and Amaranthus retroflexus as the natural host of BBWV is the first discovery in China. The use of pyrethrins and mineral oil to cure aphids is not only effective, but also promotes growth and yield effects.
