摘要
螺旋粉虱的为害对番石榴的产量、口感和品质造成不同程度的影响,实验结果表明:(1)珍珠番石榴的螺旋粉虱受害指数达73.07时,其产量损失率高达86.09%;(2)螺旋粉虱的为害对番石榴果实中N,P,K,Ca,Zn,可溶性糖,蛋白质,pH和硬度均未产生显著影响,但却显著降低了果实中VitC,Mn,Zn和可溶性固形物的含量。
The effects of spiraling whitefly on yield loss and quality in guava are very serious since its invasion in Hainan in 2006. Our experiment data indicated that spiraling whitefly caused significant yield loss up to 86.09% or more under untreated conditions when the damage severity index was 73.07; the spiraling whiteflies caused the reduction of the content of VitC and Zn in fruits significantly,but it did not cause any significant changes of the content of N,Ca,P,K,Zn,Mn,protein and soluble sugar in the fruits.
