识别与危害Identification & damage
甘蔗轻型花叶病毒与甘蔗花叶病毒不同,不能只看名字归成一种。感染株可能没有明显花纹,叶片看着正常也不能排除感染。
SCMMV differs from sugarcane mosaic virus; similar names are not identities. Infected plants may look normal; absence of mottling cannot exclude infection.
来源与传播Origins & spread
繁殖材料需要检测和溯源,别把未检种茎当作无病毒材料。片中种茎镜头表示种源风险,不代表肉眼能看见带毒状态。研究报道甘蔗粉蚧能够传播这一病毒,检查要翻到叶鞘下面。但发现粉蚧不等于发现病毒,媒介线索仍要结合病原检测。
Test and trace planting stock; untested setts are not virus-free stock. The appearance of planting stock cannot establish whether it carries the virus. Pink sugarcane mealybug transmission is reported; inspect beneath leaf sheaths. Finding a mealybug does not establish virus presence; testing is still needed.
生活史与微观过程Life cycle & microscopic processes
微观小图用细长弯曲线表示病毒颗粒,不是肉眼可见的虫。病毒依赖活细胞复制,示意颜色和大小不是真实显微测量。早期报道常有混合感染,不能把所有黄化和减产归给它。轻型这个名称,也不等于已证明它在每个品种上都没有影响。
The virus has long, flexuous particles and replicates in living cells. Its particles cannot be identified by unaided visual inspection. Mixed infections complicate reports; do not attribute every loss to SCMMV. Its mild name does not prove harmlessness in every variety.
田间检查与确认Inspection & confirmation
联系实验室安排针对性的核酸检测,按要求采叶并标记种源。检测结果要结合取样质量和其他病毒检查,由技术人员解释。
Arrange targeted molecular testing and label samples by planting-stock source. Interpret results with sample quality and other virus tests in mind.
预防、治理与复查Prevention, management & follow-up
预防重点是检测合格的种苗、苗圃监测和材料流向记录。检出带毒材料后先停止留种和调运,再按当地方案处置。媒介管理有助降低传播风险,杀虫剂不能治愈已经感染的甘蔗。保存检测与复查记录,不用一次外观好转代替病毒检测。
Prioritise tested planting stock, nursery monitoring and movement records. Stop propagation and movement of positive material pending local management advice. Vector management addresses spread; insecticides cannot cure infected cane. Keep testing and follow-up records; improved appearance is not a virus test.
