| 中文摘要: |
| 对杏树桃粉大尾蚜及其天敌种群动态进行了系统调查研究。结果表明，杏树桃粉大尾蚜4月初开始发生，6月初达到高峰期，7月中旬逐渐消退。其天敌主要由桃瘤蚜茧蜂［Fovephedrus persicae (Froggatt)］、大灰后食蚜蝇［Metasyrphus corollae (Fabricius)］、多异瓢虫 ［Hippodamia variegata (Goeze)］、菱斑巧瓢虫［Oenopia conglobata (Linnaeus)］、十一星瓢虫 (Coccinella undecimpunctata Linnaeus)和丽草蛉(Chrysopa formosa Brauer)构成，各种天敌在时间上对桃粉大尾蚜有明显的跟随效应。采用时间生态位法和灰色关联分析研究了各种天敌与桃粉大尾蚜种群数量之间的关系。在明确桃粉大尾蚜及其天敌种群动态的基础上，为桃粉大尾蚜天敌评价提供理论依据。 |
| 英文摘要: |
| Population dynamics of Hyalopterus amygdali Blanchard and its natural enemies on apricot tree were investigated. The results showed that H.amygdali occurred in early April, reached its peak in early June, and disappeared in mid July. Its natural enemies include Fovephedrus persicae(Froggatt), Metasyrphus corollae(Fabricius), Hippodamiavariegata(Goeze), Oenopia conglobata(Linnaeus), Coccinella undecimpunctata Linnaeus and Chrysopa formosa Brauer. All natural enemies had great following effect on H.amygdali. The temporal niche and grey relation grade analysis were used to analyze the relationship between the quantities of H.amygdali and its natural enemies. Based on elucidating the population dynamics of H.amygdali and its enemies，the results provide a theory basis for evaluation of its natural enemies. |
