The reproduction of apterous and alate morphs of the aphids Sitobion avenae and Metopolophium dirhodum is compared on the basis of fecundity in 5- and 10-day periods of adult life. Apterae of both species are consistently more fecund than alatae of comparable weight, producing about three more nymphs on average in any 5-day period. The reproductive differences are related to the number and quality of embryos at eclosion and to ovulation rates, both of which in turn appear to be linked to wing-muscle maintenance. These relationships between weight, embryos and reproduction may be used to predict a newly moulted adult aphid's fecundity, a method which may facilitate the assessment of resistance to aphids in new cereal varieties, by obviating lengthy recording of reproduction. The strategies by which alatae of these and other aphid species minimize the difference between their fecundity and that of apterae are discussed.
基于麦长管蚜和二叉蚜无翅型和有翅型成虫在5天和10天成年期内的繁殖力，对它们的繁殖情况进行了比较。两种蚜虫的无翅型在同等体重下始终比有翅型繁殖力更强，在任何5天时间段内平均多产约三只若虫。繁殖差异与羽化时胚胎的数量和质量以及排卵率有关，而这两者似乎又与翅肌维持有关。体重、胚胎与繁殖之间的这些关系可用于预测新蜕皮成年蚜虫的繁殖力，这种方法通过避免长时间记录繁殖情况，可能有助于评估新谷物品种对蚜虫的抗性。文中还讨论了这些蚜虫物种以及其他蚜虫物种的有翅型将其繁殖力与无翅型繁殖力差异最小化的策略。
