复叶槭Ａｃｅｒ ｎｅｇｕｎｄｏ Ｌｉｎｎ．对防护林光肩星天牛Ａｎｏｐｌｏｐｈｏｒａ ｇｌａｂｒｉｐｅｎｎｉｓ（Ｍｏｔｓｃｈ．）成虫具有较强的诱集作用。自然情况下，宁夏防护林中复叶槭对１００ｍ 范围内的光肩星天牛的诱集率至少可达６６％ ；诱集距离至少可达２４０ｍ ；诱集数量与当时天牛羽化数量正相关，可用于监测其种群数量变动；诱集数量与天气有关，雨天最少，而晴天和阴天的诱集量十分接近；复叶槭树体越大，当年生小枝越多，诱集量也越大。
Acer negundo Linn. Strong protective effect on adults of Anoplophora glabripennis (Motsch.), A shelter forest. Under natural conditions, the senescence of Acer asiatica in shelterbelts in Ningxia can reach at least 66% at least within the range of 100m. The trapping distance is at least 240m. The number of trapping seasons is positively correlated with the number of females at that time, The quantity of the population changed. The quantity of the trap was related to the weather, with the least amount of rainy days and the sunny and cloudy days. The bigger the compound maple tree body was, the more the annual branchlets were and the more the quantity of trap was.
