概括

这项风险评估评估了从英国进口的树的植物健康状况,确定了像Meloidogyne fallax.这样的关键害虫. 大型标本树带来更高的感染风险,但减轻措施的目标是无害虫.

科学领域:

植物健康风险评估
植物病理学植物病理学
昆虫学昆虫学是一门学科.

背景情况:

欧盟委员会委托对高风险植物进口进行风险评估.
这项研究的重点是来自英国的Betula pendula和B. pubescens.
商品范围从接种木到大样本树.

研究的目的:

评估与从英国进口木植物相关的植物健康风险.
评估与欧盟和保护区相关的特定检疫害虫.
根据拟议的风险减轻措施,确定无害虫的可能性.

主要方法:

进口木商品按类型和年龄分类.
根据定义的标准识别和评估相关害虫.
英国提供的风险减缓措施的评估.
专家知识诱导 (EKE) 用于量化害虫无害的可能性.

主要成果:

选择了四种关键的害虫:梅洛伊多基内,Phytophthora ramorum,Entoleuca mammata和Thaumetopoea processionea. 这四种害虫是主要的害虫.
植物年龄是一个重要因素,较大的树木会带来更大的检查挑战和更高的感染潜力.
梅洛伊多基因 (Meloidogyne fallax) 被确定为最常见的预期害虫.
专家判断表明,大型样本树很可能没有害虫 (M. fallax的确定性为97.35-100%).

结论:

降低风险的措施对于确保进口树植物的植物卫生安全至关重要.
进口植物的年龄和大小显著影响害虫风险和检测难度.
进一步评估和遵守缓解协议是必要的,以管理已识别的害虫风险.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
