1.小菜蛾Plutella xylostella在英国的高空风媒迁移在2000年的调查（a）通过垂直雷达和空中网直接监测昆虫飞行，（B）通过光陷阱网络推断的小菜蛾丰度的时间变化的证据。通过连续运行的垂直观察雷达获得的大小和形状数据的独特组合来识别迁移的小菜蛾。雷达探测到的迁徙飞越与英国一个由渔获量估计的小菜蛾丰度的相关峰值显著相关。灯诱网宽，但灯诱滞后1 d时相关性较强.在英国首次捕获的小菜蛾。发生在5月初，并伴随着从东部雷达上的迁移。雷达数据和回溯表明，从荷兰到英格兰南部的主要风媒迁移发生在5月初，这是建立英国的原因。人口。对英国早季小菜蛾的起源进行了讨论。
1. The high-altitude wind-borne migration of the diamondback moth Plutella xylostella in the U.K. in 2000 was investigated (a) by direct monitoring of insect flight by vertical-looking radar and by aerial netting, and (b) through evidence of temporal variation in P. xylostella abundance deduced from a network of light traps.2. Migrating P. xylostella were identified by a unique combination of size and shape data derived from the continuously operating vertical-looking radar.3. Radar-detected migratory overflights correlated significantly with associated peaks in abundance of P. xylostella estimated by catches in a U.K.-wide light trap network; however the correlation was stronger when light trap catches were lagged by 1 day.4. The first notable catches of P. xylostella in the U.K. occurred in early May, and were accompanied by migrations over the radar from the east.5. Radar data and back-tracking indicated that a major wind-borne migration of P. xylostella from The Netherlands to southern England took place in early May, and that this was responsible for the establishment of the U.K. population.6. The origin of early-season P. xylostella occurring in Britain is discussed.
