摘要: 烟粉虱危害青萝卜造成其叶脉、表皮及木质部变白(白心)。随着接虫密度的增大。青萝卜叶脉变白株率、外表皮退绿株率和白心率依次增加,单株有虫40头以下时,青萝卜白心率在10%以下。

Abstract: Bemisia tabaci can induce silver appearance in the vein, cuticle, and xylem of green radish. The relationship between feeding population of Bemisia and silver appearance rate is direct ratio: the higher density of bemisia, the higher ration of silver appearance in vein, cuticle, and xylem of green radish. The ration of silver appearance in xylem of green radish was under 10% when the Bemisia density was under 40 on each radish plant.
