鳞球茎茎线虫风险分析

本风险分析遵循联合国粮农组织(FAO)国际植物保护公约(IPPC)有害生物风险分析准则,从地理和管理标准,定殖和定殖后扩散的可能性、经济影响评估和传入的可能性及风险管理措施等6个方面对鳞球茎茎线虫进行了风险评估,结果证实了鳞球茎茎线虫符合检疫性有害生物的地理和管理标准,在中国定殖的可能性和定殖后扩散的可能性以及对经济影响和进入的可能性都很大,从而鳞球茎茎线虫随从疫区的黑麦、燕麦、玉米、甜菜、向日葵、蚕豆、豌豆、黄瓜、洋葱、烟草等植物繁殖材料而传入中国的风险极高,因此将鳞球茎茎线虫列为禁止输入的危险性有害生物。是非常必要的。

RISK ANALYSIS OF DITYLENCHUS DIPSACI (KUHN) FILIJIEV

The risk analysis is abided by the pest risk analysis criterion which was formulated by FAO and IPPC, and evaluates the bulb that based on six aspects: geography standard ,manage measure, establish and possibility of later spreading ,estimate of economic influence, possibility of entering and risk manage measures. The results confirm that bulb accords tally with the geography and manage standards of quarantine pest in China. There is much possibility of economic influence and entering. Thus, the risk is much for Ditylenchus dipsaci enter China from epidemic area propagate material of rye, oat, corn, sugar beet, sun flower, broad bean, pea, cucumber, onion, tobacco.
