【摘要】 吸虫塔(suction trap)是用来监测麦类蚜虫和大豆蚜Aphis glycines迁飞种群动态的大型植保测报设备,在欧洲和北美洲已经呈网络安装分布,为蚜虫的预警和防控提供重要依据。作者借鉴欧美吸虫塔的工作原理和设计,设计并生产了符合我国地域特征的吸虫塔设备,在东北、华北、华中、华东、西北等地布点安装了21台,用于监控我国麦类蚜虫和大豆蚜的迁飞动态,初步形成覆盖我国小麦主产区和大豆主产区的吸虫塔网络系统。此吸虫塔总高8.8m,由底部轴流风机运转产生的负压在塔顶部形成吸力,将迁飞经附近的小型昆虫吸入塔管,最后落入下部的样品收集瓶中,以此获得其迁飞的动态数据。吸虫塔网络的构建和完善,不仅为麦类蚜虫和大豆蚜的监控提供支撑,同时也为其它小型迁飞性昆虫监测、种群动态、生物多样性、生物信息学等研究提供数据。更多还原

【Abstract】 Suction traps are a plant protection device that can also be used to monitor the aerial population dynamics of small insects,especially aphids.For example,networks of these traps have been constructed in Europe to monitor the migration of wheat aphids and in North America to monitor the migration of the soybean aphid Aphis glycines.These networks have played an important role in controlling these pests.Following the operational principle and design of established suction trap networks in Europe and North America,we produced 21 traps and installed these in sites in northeastern,central and northwestern China.The original 21 traps have now been incorporated into a preliminary suction trap network covering China’s main wheat and soybean growing areas.The height of each trap is 8.8 m compared to 12 m in Europe and 7.8 m in North America.Extending and completing the network will not only provide early warning of aphid outbreaks in wheat and soybean crops,but will also provide useful scientific data on the population dynamics,bioinformatics,and biodiversity of other migratory insects.更多还原
