为了观察植物抗性压力对麦长管蚜（ｓｉｔｏｂｉｏｎ　ａｖｅｎｕｅ　Ｆａｂｒ．）繁殖的影响，本文研究了蚜虫在抗性小麦品种和敏感小麦品种上从出生到死亡的寿命、繁殖、成虫重量及生殖腺状态；还研究了无翅蚜在两类品种间的迁移状况。将这种结果与若虫期或成虫期饥饿１０或１４ｈ后的蚜虫所获参数进行了比较。用成虫做试验的抗性植株与用幼虫做试验的同一植株所测得的每一参数都极为不同，在抗性小麦上生长和繁殖的蚜虫与受半饥饿影响的蚜虫非常相似。 In order to observe the effects of plant stress on the reproduction of sitobion avenue Fabr., This paper studied the lifespan, reproduction, adult weight and gonad state of aphids from birth to death on resistant and susceptible wheat cultivars. The migration of aphid-free aphids between two species was also studied. The results were compared with those obtained after aphids were starved for 10 or 14 h in the nymphal stage or adult stage. Each of the resistant plants tested with the adult and the same plant tested with the larvae was very different in that the aphids that grew and multiplied on the resistant wheat were very similar to the aphids affected by the half-starvation.
