The host selection and oviposition choice behavior of Micromelalopha sieversi (Staudinger) among five Populus deltoids clones were observed by observation, and the host volatile extract were prepared for the purpose of comparing the differences in host selectivity, analyzing the impact of volatile substances on the moth host selection. The results showed that there were different host selection rates of different gender and physiological state moths. The females showed differences in host selectivity, while the males did not. There were more mated female moths made host choices than the virgin moths. The statistical results of host oviposition selectivity suggested that Biyu had the strongest oviposition attractant activity, followed by Populus×canadenesis ‘Guariento’, but there were no significant differences among the other treatments and controls. 为比较杨小舟蛾对不同寄主的选择差异性，利用生物观察法研究了该成虫在5种黑杨无性系寄主间的停靠选择行为和产卵选择行为，验证了5种寄主挥发物对该虫进行寄主选择过程产生的作用。结果表明：不同性别、不同生理状态的成虫对5种寄主的选择率存在差异；雌性个体无论是否交配均表现出对5种样本相同的差异性选择，而雄性个体则未表现出这种选择差
