同翅目：蚜虫科豇豆蚜（Aphis craccivora Koch）和豌豆蚜（Acyrthosiphon pisum (Harris)）对豇豆（Vigna unguiculata (L.)）吸收氮、磷及生长的影响Walp。简历。蚕豆(Vicia faba L. cv。水生)，和园豌豆(Pisum sativum L. cv。Victory freeze)幼苗进行了研究。蚜虫侵染10 d后，除豌豆-豌豆蚜虫外，所有植物-蚜虫组合的植株干重、平均相对生长率和单位叶率均显著降低。侵染植物和对照植物的平均叶面积比相同，表明侵染植物对蚜虫取食没有重新分配同化物资源。N和P积累占植物干重的百分比在对照和侵染植物之间没有差异，并且是所检查的物种特有的。处理后对照植株的N、P绝对含量均高于对照植株。
The effects of cowpea aphids (Aphis craccivora Koch) and pea aphids (Acyrthosiphon pisum (Harris)), both Homptera: Aphididae, on nitrogen (N) and phosphorus (P) uptake by and growth of cowpea (Vigna unguiculata (L.) Walp. cv. Caloona), broad bean (Vicia faba L. cv. Aquadulce), and garden pea (Pisum sativum L. cv. Victory Freezer) seedlings were investigated. After 10 days of aphid infestation, all leaf areas were significantly lower in infested plants, and plant dry weight, mean relative growth rate, and unit leaf rate were significantly lower in all plant–aphid combinations except for pea – pea aphids. The mean leaf area ratio was the same for infested and control plants indicating that infested plants did not reallocate their assimilate resources in response to aphid feeding. The accumulation of N and P as a percentage of plant dry weight did not differ between control and infested plants and was specific to the species examined. However, control plants all had greater absolute amounts of N and P after ...
