在沙特阿拉伯进行的一次考察中,发现了柑桔黄龙病的两种传病媒介,即柑桔木虱(Diaphorina Citri)和非洲木虱(Trioza erytreae)。亚洲型和非洲型黄龙病都有可能发生。对阿拉伯也门共和国的类似考察表明,该国的一些地区也有黄龙病,但只限于高海拔地区。在沙特阿拉伯,传病媒介主要是柑桔木虱;在阿拉伯也门共和国主要是非洲木虱,其黄龙病可能属非洲型。本文还简述了黄龙病的检测和防治新技术。 In a study conducted in Saudi Arabia, two vectors for citrus Huanglongbing were identified, namely Diaphorina Citri and Trioza erytreae. Asian-type and African-type yellow dragon may have occurred. A similar study of the Arab Republic of Yemen shows that some areas of the country also have yellow dragon’s disease, but only in high elevations. In Saudi Arabia, the vector is predominantly citrus psyllid; in the Arab Republic of Yemen, predominantly African psyllids, the yellow dragon’s disease may be of the African type. This article also briefly describes the detection and prevention of yellow dragon’s disease new technology.
