摘 要: 研究了广州地区美洲斑潜蝇寄生性天敌的种类及发生动态,以及华南毛蕨、苦瓜、飞机草等植物提取物对寄生蜂的影响。研究结果表明,广州地区美洲斑潜蝇寄生蜂有姬小蜂科、茧蜂科11种。主要寄生蜂为姬小蜂科种类,其中底比斯釉姬小蜂Chrysocharis pentheus(walker)为寄生美洲斑潜蝇的优势寄生蜂,其次是丽灿姬小蜂Chrysonotomyia formosa(Westwood)和冈崎灿姬小蜂Ch.okazakii(Kamijo)。研究了植物提取物对底比斯釉姬小蜂的羽化率和寄生率的影响,结果表明,植物提取物对寄生蜂是相对安全的,已商品化的印楝素乳油制剂对其也同样是安全的。 Species of parasitic bees on Liriomyza sativae, happen conditions of population in the field and effect of extracts from the plant of Cyclosorus parasiticus, Momordica charantia and Chromolaena odorata on adults bees were researched in Guangzhou. Among parasitic bees of L. sativae, Chrysonotomyia formosa, Ch. okazakii and Chrysocharis pentheus were the main natural larvae enemies and play an important role in ecological control. Tests also indicated that extracts of the plants had little influence on eclosion rate of larva and pupa and parasitic rate of Chrysocharis pentheus adult.
