摘要
2016—2017年,利用扫网法系统调查了北疆棉田周边的非作物生境中9科13种常见植物上的食蚜蝇种群发生情况。研究发现,食蚜蝇种群密度在不同植物上有显著差异,种群发生高峰主要集中在各种植物开花期,种群消长还与这些植物上的蚜虫发生有明显跟随关系。5—6月,食蚜蝇在大部分植物上都有发生,但主要集中于新疆大蒜芥和罗布麻等;7—8月,在碱蓬、大麻、顶羽菊等上种群密度高;9月,主要在甘草、顶羽菊、罗布麻等上。本研究为今后充分利用棉田周边非作物生境,提升对食蚜蝇种群保育功能及棉花害虫生态控制水平提供了科学依据。
In 2016 and 2017, the population dynamics of hoverflies in non-crop habitats(including 13 plant species from 9 families) surrounding cotton fields were monitored using a sweeping method in northern Xinjiang. The population densities of hoverflies varied greatly on different plants. However, the populations usually peaked during the flowering periods of the plants and co-occurred in a follow-up pattern with aphid population dynamics. The preferred plant species of hoverflies varied with season. From May to June, high hoverfly densities were found on Sisymbrium loeselii and Apocynum venetum. In July and August, the densities were high on Suaeda glauca, Cannabis sativa and Acroptilon repens. While in September, hoverflies shifted to other plants such as Glycyrrhiza uralensis, A. repens and A. venetum. The results are significant for utilizing non-crop habitats to enhance the hoverfly abundance and their potential biocontrol services in cotton planting systems.
