摘要
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。
Systematic field investigations on Aphidius avenae Haliday were conducted in 1975-1991 in Jinan City, Shandong Province. The regulation of its population dynamics was determined, its aphid control capability was divided into four types, and the preservation and utilization practices were correspondingly proposed. Based on a number of phenomena such as no dormant type of this parasitoid was found in winter and summer. weak tolerance to high or low temperature, sudden-increase and -decline of adult, population, consistent occurrence time in high mountains and plains or islands and dry lands,and the successive occurrence time in adjacent regions in Eastern China, it was indicated that this parasitoid can be seasonally long distance migratory with its host insect pest-Sitobion avenae from south to north.
