目的对苍海公园红火蚁侵害状况进行调查,了解红火蚁的危害情况,为科学防治红火蚁提供依据。方法将苍海公园分为对开湖岸区、九孔桥和恩义村区、城市园林园区等3大区域,采用抽样调查方法调查统计活动蚁巢和诱集工蚁数量。结果 3个区域的草坪绿地的红火蚁活动蚁巢平均密度分别为0.084、0.093、0.066个/m2;诱集到活动工蚁诱集比率分别为83.3%、76.7%、43.3%;早期建成区以大型蚁巢为主,新建成区以小型蚁巢为主。早期建成区蚁巢密度和诱集工蚁数量明显高于新建成区。结论苍海公园的红火蚁均系由于新植入的草皮和植物带入,由于没有有效的检疫和控制,导致蚁群不断扩大和大量繁殖,对人们的休闲活动和工作造成了较大的影响,应进行综合治理予以及时控制。 Objective To investigate the status of red imported fire ant in Canghai Park, understand the harm situation of red imported fire ant, and provide evidence for the scientific control of red imported fire ant. Methods Canghai Park was divided into three major areas, ie open lake area, Jiukong Bridge and Enyi Village, urban garden area and so on. Sampling survey was used to investigate the number of active nest and seeding workers. Results The average density of ant nucleus activity of the red imported fire ant in the green lawns of the three regions were 0.084, 0.093 and 0.066 / m2 respectively. The trap entrapment rates of the workers were 83.3%, 76.7% and 43.3%, respectively. Ant nest, the new built area to a small nest-based. The density of ant nests and the number of trapped workers in early built-up areas were significantly higher than those in newly built areas. Conclusion All the red imported fire ant in Canghai Park was brought in by the newly introduced turf and plants. Due to the lack of effective quarantine and control, the ant colonies were continuously expanded and multiplied, which had a great impact on people’s leisure activities and work , Should be comprehensive management to be timely control.
