从侵染水稻的水稻植株上分离到水稻东格罗杆状病毒(RTBV)和水稻东格罗球状病毒(RTSV)。在感染RTBV和RTSV的水稻植株上，绿叶蝉可单独或与RTSV一起传播RTBV，但不能单独传播RTBV，而RTSV单独传播。当叶蝉以前在RTSV病株上取食时，也会发生叶蝉传播RTBV。利用叶蝉传播RTBV的RTSV和假设的“辅助因子”的最小获取访问周期为10min，并且在30min访问中获取RTBV。“辅助因子”被叶蝉保留了7天，而RTSV保留了2天。在蜕皮后，“辅助因子”没有保留在叶蝉体内。
Rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV) were isolated from rice plant infected with a Philippines isolate of tungro. RTBV was transmitted alone or together with RTSV by the leafhopper Nephotettix virescens from rice plants infected with both RTBV and RTSV, but not from plants with RTBV alone, while RTSV was transmitted alone. RTBV transmission by the leafhopper also occurred when the leafhoppers were previously fed on RTSV diseased plants. The minimum acquisition access period of RTSV and hypothetical “helper factor” for RTBV transmission by the leafhopper was 10min, and RTBV was acquired in a 30min access. The “helper factor” was retained for 7 days by the leafhopper, whereas RTSV was retained for 2 days. The “helper factor” was not retained in the leafhopper after the moulting.
