| 摘 要： | 通过田间采样和室内饲养观察表明，梨黄粉蚜生活周期为同寄主全周期型，在景泰地区年发生５～６代。以受精卵主要聚集在果苔帽下越冬，翌年春，日均温达９～７℃以上时，越冬卵始孵化，４月中至５月初为孵化盛期，末期持续至６月中、下旬。

| Abstract: | The lifecycle of pear yellow phylloxerid( Cinacium iakasuinse Kishi) is a full-periodism with host, it takes place 5～6 generations eachyear in region of Jintai.Fertilized egg hibernates by gathernig below cup offruit handle. When mean temperature goes up 9.7℃ next spring, overwinteredegg starts to hatch. The flourishing stage hatching is from mid-April to earlyMay. The last stage goes on to middle and later of June. |
