Abstract: The results of field investigation and experiment showed that the S. avenae had two kinds of ecotype,i.e.ear-type and seedling-type.The ear-type aphid is only an ecotype adapting high temperature, which has two kinds of typical body color: (1) orange-red, and (2) greenish, Meanwhile there is an intermediate colored one the yellowish-green. The orange-red aphids are produced from the yellowish-green aphids which are from the green ones. The range of optimal temperature is from 15-20℃ for seedling-type aphids, and from 24-26℃ for ear-type ones which are the major type of S. avenae for overwintering (account for 96%).
