摘要
在塔斯马尼亚西北部的三个地点进行的试验监测了地下三叶草红叶病毒通过其载体 Aulacorthum solani 的移动进入蚕豆作物及其内部的传播情况。记录表明，作物内几乎所有的感染都是由于迁徙的有翼菌在作物出苗后不久建立了极少数侵染和感染病灶后，无翼菌的二次传播造成的。喷洒内吸磷-S-甲基可减少病毒在作物内的传播。三个地点收获时已喷洒农药的地块的感染发生率分别为 23%、13% 和 23%，而未喷洒农药的地块的感染发生率分别为 80%、31% 和 84%。喷洒后产量增加了 980、420 和 540 公斤/公顷。
SUMMARY
Trials at three sites in north-western Tasmania monitored the spread of subterranean clover red leaf virus into and within broad bean crops with movement of its vector, Aulacorthum solani. Records indicated that almost all infections within the crops resulted from secondary spread by apterae following the establishment by migrant alatae of a very few foci of infestation and infection soon after crop emergence. Spread of the virus within the crops was reduced by sprays of demeton-S-methyl. Incidence of infection in sprayed plots at harvest was 23%, 13% and 23% at the three sites compared with 80%, 31% and 84% respectively, in unsprayed plots. Yield increases as a result of spraying were 980, 420 and 540 kg/ha.
