蚕豆蚜饲养的2个品种的领域豆，他们不同的繁殖力，和固体和氮的摄入量和同化的总金额在幼虫的生活，在生殖和生殖后早期的生活进行了估计。幼虫在7天的生活中摄入0.7-0.8毫克固体，含0.02-0.03毫克氮，他们摄入和排泄更多的固体和氮从一个品种。成虫在3周的生殖期内可摄取4.4-4.9 mg含氮量为0.08-0.09 mg的固体;它们从每个品种中摄取几乎等量的固体，与幼虫一样，同化约20%;它们的干重在生殖期缓慢增加，在生殖后早期迅速增加。成人同化70%，幼虫50%的氮摄入，虽然幼虫同化和排泄显着更多的氮在一个品种，成人同化更多的氮在其他品种上，他们产生显着更多的幼虫。两个品种的汁液中的氮含量似乎超过足够的蚜虫生长和繁殖，并没有决定繁殖力。
Aphis fabae were reared on 2 varieties of field beans on which they differ in fecundity, and the total amounts of solids and nitrogen ingested and assimilated during larval life and during the reproductive and early post-reproductive life were estimated. Larvae ingested 0.7-0.8 mg solids containing 0.02-0.03 mg nitrogen in 7 days of larval life; they ingested and excreted more solids and nitrogen from 1 variety. Adult virginoparae ingested 4.4-4.9 mg solids containing 0.08-0.09 mg nitrogen during the reproductive life of 3 weeks; they ingested almost equal amounts of solids from each variety and, like the larvae, assimilated about 20%; their dry weights increased slowly during reproductive life and rapidly during early post-reproductive life. Adults assimilated 70% and larvae 50% of the nitrogen ingested and although larvae assimilated and excreted significantly more nitrogen on one variety, the adults assimilated more nitrogen on the other variety on which they produced significantly more larvae. The nitrogen content of the sap of both varieties seems more than adequate for the aphids to grow and reproduce and did not determine fecundity.
