Soybean dwarf virus (SbDV) exists as several distinct strains based on symptomatology, vector specificity, and host range. Originally characterized Japanese isolates of SbDV were specifically transmitted by Aulacorthum solani. More recently, additional Japanese isolates and endemic U.S. isolates have been shown to be transmitted by several different aphid species. The soybean aphid, Aphis glycines, the only aphid that colonizes soybean, has been shown to be a very inefficient vector of some SbDV isolates from Japan and the United States. Transmission experiments have shown that the soybean aphid can transmit certain isolates of SbDV from soybean to soybean and clover species and from clover to clover and soybean with long acquisition and inoculation access periods. Although transmission of SbDV by the soybean aphid is very inefficient, the large soybean aphid populations that develop on soybean may have epidemiological potential to produce serious SbDV-induced yield losses.
大豆矮缩病毒（SbDV）根据症状学、传毒介体特异性和寄主范围可分为几个不同的株系。最初鉴定的日本SbDV分离株是由茄无网蚜特异性传播的。最近，更多的日本分离株和美国本土分离株已被证明可由几种不同的蚜虫物种传播。大豆蚜是唯一在大豆上定殖的蚜虫，已被证明是来自日本和美国的一些SbDV分离株的低效传毒介体。传播试验表明，大豆蚜能够在较长的获毒和接种饲育期下，将某些SbDV分离株从大豆传播到大豆和三叶草物种，以及从三叶草传播到三叶草和大豆。虽然大豆蚜传播SbDV的效率很低，但在大豆上形成的大量大豆蚜种群可能具有流行病学潜力，导致由SbDV引起的严重产量损失。
