| 中文摘要: |
| 丁香北京瘿蚊Pekinomyia syringae Jiao & Kolesik以幼虫在北京丁香Syringa reticulata subsp. pekinensis和暴马丁香Syringa reticulata subsp. amurensis叶片内隐蔽为害，为害严重时导致寄主提前落叶。通过林间调查和室内试验，对其生活史、习性研究发现，该瘿蚊在北京1 a发生1代，以老熟幼虫在表土层结茧越冬。3月初越冬幼虫开始化蛹，成虫羽化盛期为3月底至4月初，成虫不需补充营养，有趋黄性，卵孵化期为4月上中旬，4-10月幼虫为害，10月老熟幼虫脱离叶片在表土层结茧越冬。本研究结果为该虫的综合防治提供了防治基础。 |
| 英文摘要: |
| Pekinomyia syringae did concealed harm inside leaves of peking lilac(Syringa reticulata subsp. pekinensis) and amur lilac(S. reticulata subsp. amurensis) in larval stages. Severe damage caused by the pest could lead to premature defoliation. Through laboratory observations and forestry investigation, life history and habits of the pest were studied. The results demonstrated that the species of gall midges occured a single generation per year in Beijing. Its mature larva spun cocoons within topsoil to overwinter. In March overwintering larva begun to pupate, and peak of insects eclosion usually occurred in the end of March or early April. The adults had no need to supplement nutrient, but had taxis to yellow. Egg incubation period occurred from early to middle of April. Therefore, larval harming stage lasted from April to October. Mature larva abscised from leaves on October, spun cocoons to overwinter. This study laid a good foundation for integrated control against P. syringae. |
