摘要
测试结果禾谷缢蚜对小麦黄矮病(BYDV)传播能力显著提高。由此可使该病由北方干旱,半干旱的中、低产麦区往水地高产麦区,甚至南方麦区扩展曼延。已于1988、1989年秋季导致陕西关中西部水地,1989年春季导致南方麦区四川荣县小麦黄矮病发生流行。
Through sereral years of experiments and researches it is shown that the transmission potential of BYDV by Rhopalosiphura padi has been drastically enhanced, This fact enabled the expansion and development of this disease from the arid and semiarid areas in the north toward the more fertile wheat field at the irrigated areas and even toward the wheat areas in the south. In 1988 and 1989 it has been successively induced the prevalence of BYDV at western Guanzhong of Shanxi Province and in spring of 1989 at Rong County of Siehuan Province severe occurence of BYDV has happened,
