摘　　要：利用3年生臭椿、新疆杨在室内建立混交林进行光肩星天牛成虫放飞试验。结果表明:臭椿、新疆杨混交林对天牛成虫的寄主选择有显著影响,天牛成虫的交尾行为只在新疆杨植株上进行;天牛成虫在林内植株上着落的总虫次随新疆杨株数的减少而下降,交尾次数也减少;臭椿、新疆杨植株数量在林分中所占比例在一定范围时,天牛成虫在新疆杨和臭椿上着落的虫次比均趋于稳定;新疆杨与臭椿以行状3∶2和2∶3混交时林分的抗虫效果较好。The host choice action of Anoplophora glabripennis was studied in different analog mixed forest of Ailanthus altissima and Populus bolleana. The result showed that the effect of the types of the mixed forests on the beetle＇ s host choice was significant. Along with the reducing of individuals of P. bolleana in the mixed stands, the landing and mating frequencies of the beetle were reduced, but the total landing frequencies of some types of mixed stand were invariably. Mating action of the beetle mainly occurred on the individuals of P. bolleana in analog stands. According to the analog stand experiment result, the two insect resistance mixed stand types （ mixed proportion was 3 ： 2 or 2 ： 3） were acquired.
