Table S2. Morphological characters useful to discriminate Aphid gossypii, Aphid monardae, Aphid oestlundi and Aphid sedi.: Explanation note: Morphological characters useful to discriminate Aphid gossypii, Aphid monardae, Aphid oestlundi and Aphid sedi. For all measurements and counts the range is given and the mean is in parentheses. All measurements in mm. Abbreviations: B base of last antennal segment, CA cauda, DBIII: Distance from the base of antennal segment III to the first secondary sensorium, HT2 second hind tarsus, LHIII longest Hair on ant. segm. III, PT: Processus terminalis, SIPH siphunculi, URS ultimate rostral segment. Data of oviparae of Aphid gossypii from Kim et al. (2010a).

表S2：用于区分棉蚜（Aphid gossypii）、薄荷蚜（Aphid monardae）、厄斯特伦蚜（Aphid oestlundi）以及景天蚜（Aphid sedi）的形态鉴别特征。注：本说明用于区分上述四种蚜虫的形态特征。所有测量及计数均给出取值范围，均值以括号标注，所有测量单位均为毫米（mm）。缩写说明：B：触角末节基部（base of last antennal segment）；CA：尾片（cauda）；DBIII：触角第Ⅲ节基部至首个次生感觉圈的距离（Distance from the base of antennal segment III to the first secondary sensorium）；HT2：后足第2跗节（second hind tarsus）；LHIII：触角第Ⅲ节最长刚毛（longest Hair on ant. segm. III）；PT：顶突（Processus terminalis）；SIPH：腹管（siphunculi）；URS：喙管末节（ultimate rostral segment）。棉蚜产卵型雌蚜的相关数据引自Kim等（2010a）的研究。
