The amounts of ecdysteroids were determined in different morphs of holocyclic monoecious aphids (Acyrthosiphon pisum Harris, Dysaphis devecta Walk., Lachnus roboris L., Schizolachnus pineti F.) and holocyclic heteroecious aphids (Aphis sambuci L., Rhopalosiphum padi L.) by means enzyme immunoassay. Among the parthenogenetic morphs (fundatrices, virginoparae, and oviparae), the fundatrices have consistently higher amounts of ecdysteroids than those of other morphs of the same species. Alate and apterous virginoparae showed slight differences in their ecdysteroid titer both in heteroecious and monoecious aphids. The migrant morphs (i.e., alate fundatrices and gynoparae) have the lowest amounts of ecdysteroids within a species. With the exception of D. devecta, the oviparae of both heteroecious and monoecious aphids have the second greatest amounts of ecdysteroids among the morphs living on same host plant. Polyphenism, dispersal behavior, and fecundity in connection with weight, ovariole number, and ecdysteroid concentration of different morphs of aphids are discussed.
通过酶免疫测定法测定了全周期两性蚜虫（豌豆蚜、云杉绿卷蚜、松大蚜、松针大蚜）和全周期异寄主蚜虫（接骨木蚜、禾谷缢管蚜）不同形态中的蜕皮甾体含量。在孤雌生殖形态（干母、性母和产卵雌蚜）中，干母的蜕皮甾体含量始终高于同一物种的其他形态。有翅和无翅性母在异寄主和两性蚜虫中的蜕皮甾体滴度略有差异。迁飞形态（即有翅干母和雌蚜）在一个物种中的蜕皮甾体含量最低。除云杉绿卷蚜外，异寄主和两性蚜虫的产卵雌蚜在同一寄主植物上生活的形态中，蜕皮甾体含量排第二。讨论了蚜虫不同形态的多型现象、扩散行为以及与体重、卵巢管数量和蜕皮甾体浓度相关的繁殖力。
