1975—1991年在济南进行燕麦蚜茧蜂田间系统调查,明确其种群动态,并将控蚜效能区分为四种类型,提出相应的保护利用措施。该蜂无越冬越夏虫态,抗高、低温能力弱,成蜂存在“突增”“突消”现象,高山与平地、海岛与陆地出现时间一致,我国东部地区发生期相互衔接。据此认为燕麦蚜茧蜂有追随寄主麦长管蚜季节性同步远距离迁飞现象。 In 1975-1991, a systematic investigation was conducted on the population of Aphidius cochinchus in Jinan, and its population dynamics were clarified. Four kinds of control aphids were divided into four types, and corresponding protection and utilization measures were put forward. The bees had no symptoms of overwintering in summer and insects, but their ability to resist high and low temperature was weak. The bees had the phenomenon of “sudden increase” and “sudden elimination”. The appearance time of alpine and plains, islands and terrestrial was the same, and the occurrence occurred in eastern China. Therefore, it is suggested that the aphid Aphis gossypii has seasonal synchronization of long-distance migrations following the host aphis gossypii.
