1984年以来,进行了介体蚜虫传毒试验,证明禾谷缢管蚜、麦长管蚜、麦无网长管蚜、麦二叉蚜及玉米蚜均可传毒,传毒发病率分别为74.2％、59.0％、53.6％、31.5％和17.4％。禾谷缢管蚜传毒特性、取食获毒或传毒最短时闻为5分钟,发病率达6.67％。2小时可充分获毒或传毒。蚜虫传毒有间歇现象,持毒期3天,传毒潜伏期65—70分钟。由此可见,小麦雨锈病是由多种蚜虫传播的具有半持久性传毒特性的病毒病。禾谷缢管蚜传毒能力因龄期不同而有所差异,有翅蚜传毒能力最强,无翅成蚜次之,若蚜最低。接种一头带毒蚜虫即可引致发病,接种蚜头数增加,发病率提高,接种7头蚜虫,发病率可达84.2％。
Since 1984, aphid-mediated toxicity tests were conducted to prove that both H. avenae, G. avenae, S. avenae and M. aphid could be transmitted and transmitted respectively 74.2%, 59.0%, 53.6%, 31.5% and 17.4%. Wo Tubifera poisonous poisoning characteristics, feeding poisoning or poisoning the shortest when the smell is 5 minutes, the incidence rate of 6.67%. 2 hours can be fully poison or poison. Aphids poisoning intermittent phenomenon, holding poisoning period of 3 days, the incubation period of 65-70 minutes. Thus, wheat rain rust disease is a virus disease with semi-persistent virus transmission transmitted by a variety of aphids. Hypothalamus aphids poisoning ability due to different ages have different, aphid the strongest transmission ability, finless winged second, if the lowest aphid. Inoculation with aphids can cause the disease, the number of inoculation spider head increased, the incidence rate increased, inoculation of seven aphids, the incidence rate of up to 84.2%.
