1985-1988 年对谷类蚜虫种群进行了采样，并检测了大麦黄矮病毒 (BYDV) 的传播情况。在生物测定中从传播 BYDV 的寄主植物中收集了稻田红管霉 (Rhopalosiphum padi)、麦迪管管管霉 (Rhopalosiphum maidis)、麦穗管霉 (Sitobion avenae)、麦地毛霉 (Metopolophium dirhodum)、禾谷裂霉 (Schizaphis graminum) 和大管霉 (Macrosiphum euphorbiae)。从植物中收集的 1028 只 Diuraphis noxia 中，有 1 只可能传播 BYDV。该分离株在血清学和生物学特征上与 SGV 相似，但由于随后测试的 800 多个 D. noxia 中的任何一个都无法恢复它，我们怀疑它可能是一种污染物。 在秋季从适合活体收集的吸力捕集器收集的蚜虫中，R. padi 传播 BYDV 的频率最高。其他传播 BYDV 的捕获物种包括：R. maidis、Rhopalosiphum insertum、Macrosiphum euphorbiae、Metopolophium dirhodum 和 Ceruraphis eriophori。经过调整的传染性指数表明，R. padi 是迄今为止爱达荷州西南部秋季播种季节 BYDV 最重要的媒介。雄性稻田R. padi 传播BYDV 的频率始终高于同一时期收集的雌性R. padi。
Populations of cereal aphids were sampled from 1985-1988 and assayed for transmission of barley yellow dwarf virus (BYDV). Rhopalosiphum padi, Rhopalosiphum maidis, Sitobion avenae, Metopolophium dirhodum, Schizaphis graminum and Macrosiphum euphorbiae collected from host plants transmitted BYDV in bioassays. Of the 1028 Diuraphis noxia collected from plants, one may have transmitted BYDV. The isolate involved resembled SGV in serological and biological characteristics, but since it was not recoverable by any of more than 800 D. noxia subsequently tested, we suspect it may have been a contaminant.Among those aphids collected during the autumn from a suction trap adapted for live collection, R. padi transmitted BYDV most frequently. Other trapped species which transmitted BYDV included: R. maidis, Rhopalosiphum insertum, Macrosiphum euphorbiae, Metopolophium dirhodum and Ceruraphis eriophori. An adapted Infectivity Index indicated that R. padi is by far the most important vector of BYDV during the autumn sowing season in southwestern Idaho. Male R. padi consistently transmitted BYDV more frequently than did females collected during the same period.
