The foxglove aphid, Aulacorthum solani (Kaltenbach), recently was documented using the invasive species pale and black swallow-wort (Vincetoxicum rossicum (Kleopow) Barbar. and V. nigrum (L.) Moench, respectively) as host plants. Because these are new host plant records for this polyphagous species, we investigated foxglove aphid development and reproduction on pale and black swallow-wort relative to a known crop host, potato (Solanum tuberosum L.), at a 25:20°C thermophase and a photoperiod of 16:8 (L:D) h. Almost no such data have been previously reported for a noneconomic host plant. Larval development and survival, as well as adult reproductive development and fecundity, were similar between the two swallow-wort species and potato. Adult aphids lived significantly longer on pale swallow-wort than the other two host plants, but this extended longevity encompassed the postreproductive stage. Foxglove aphid population parameters were therefore similar among the three plant species as well as most previous reports on crop plants. Pale and black swallow-wort appear to be suitable secondary hosts for foxglove aphid; other factors possibly limit aphid abundance on these two plant species in the field.
最近有文献记载，毛地黄蚜（Aulacorthum solani (Kaltenbach)）会将入侵物种浅色和黑色白前（分别为萝藦科白前属植物Vincetoxicum rossicum (Kleopow) Barbar.和V. nigrum (L.) Moench）用作寄主植物。由于这是这种多食性物种新的寄主植物记录，我们在25:20°C的热周期和16:8（光照:黑暗）小时的光周期条件下，研究了毛地黄蚜在浅色和黑色白前上相对于已知作物寄主马铃薯（Solanum tuberosum L.）的发育和繁殖情况。此前几乎没有关于非经济寄主植物的此类数据报道。两种白前物种和马铃薯之间，幼虫的发育和存活情况，以及成虫的生殖发育和繁殖力都相似。成虫在浅色白前上的存活时间明显长于其他两种寄主植物，但这种延长的寿命包括了生殖后期。因此，毛地黄蚜在这三种植物物种上的种群参数与之前关于作物植物的大多数报道相似。浅色和黑色白前似乎是毛地黄蚜合适的次要寄主；其他因素可能限制了这两种植物物种在田间的蚜虫数量。
