title: [Effects of spring wheat varieties on growth, development and fecundity of Sitobion avenae (F.) (Homoptera: Aphididae)].
abstract: Effects of seven varieties of spring wheat on the population parameters of Sitobion avenae (F.) were investigated at 25 degrees C in the laboratory. The results indicated that there were significant differences in the developmental duration, mortality of nymph aphids, the longevity and fecundity of adults. The adults had shorter longevity and poorer fecundity when reared with the leaves of higher resistant w heat varieties. The level of wheat resistance was in order of Liaochun 10 >02C-MB >Xinchun 6 >Bafeng 1> Yongliang 4> Neimai 19> Menghua 1 using the intrinsic rate of increase (r(m)) as an index of wheat antibiosis to aphids, which was correspondent well with that in fields.
