关于水稻褐飞虱Nlaparvata lugens Stal越冬寄主的研究,目前国内一致认为,水稻和普通野生稻OrgzaSativa f.Spontanea是褐飞虱安全越冬的主要寄主,并将它们作为褐飞虱安全越冬的生态指标。但对游草Learsta hexandra Sw.能否成为褐飞虱越冬寄主,自1958年湖南雷惠质等同志报道褐飞虱可以卵在当地游草上越冬到现在,仍然众说纷云,争论不休。对于游草是不是褐飞虱越冬寄主,本人认为:在翌年有水稻作为交替食料的地区,褐飞虱当年可以卵在当地游草上越冬,游草作为越冬的转主寄主,但不能成为褐飞虱连续完成一个世代的越冬寄主。
As for the host of the Nilaparvata lugens Stal overwintering host planthopper in China, at present, it is agreed that the rice and common wild rice OrgzaSativa f.Spontanea are the main hosts for the safety of the N. lugens overwintering, and they are used as ecological indicators for the safety of the N. lugens overwintering. However, whether or not Legsta hexandra Sw. Can become the host of BPH overwintering, since the comrades of Hunan Province in 1958, Lewyte Hexandra Sw. Can report that the BPH can survive over the winter in the local grass weeds, it still remains controversial. For the grass is not the host of BPH overwintering host, I think: In the following year there is rice as an alternate foodstuff area, the year of the BPH can egg overwinter in the local grass, grass as the host of overwintering, but can not be a succession of brown planthopper to complete a generation Overwintering host.
