摘要:
系统调查分析了福建省龙岩市新罗区大池镇红火蚁的入侵源、发生分布、扩散危害、疫区生境、蚁巢密度和蚁丘大小等,结果表明该地区红火蚁来源是5年前区域内废品塑料再生加工厂从广东购进废旧塑料袋夹带,造成红火蚁入侵定居。红火蚁自然扩散受各种因素的影响,在疫区内不同方向扩散距离在53～297m,影响因素主要有:地表受阳光照射程度、人为干扰程度和不同生境类型等,各因素对红火蚁分布与扩散的影响是相互作用的。

Abstract:
The imported red fire ant (IRFA),Solenopsis invicta Buren,is a notorious,dangerous invader species in the world. An investigation was carried out on IRFA in Dachi Town,Xinluo District,Longyan,Fujian. The study included the invader's origins,occurrence,distribution,hazard-spreading,infested habitats and colony density,as well as size of their mounds. Survey results showed that IRFA was initially from a local plastics recycling factory. Five years ago,the factory purchased waste plastic bags from Guangdong that brought IRFA into the region. The ants spread 53-297 m in diameter from the quarantined area. The distribution of IRFA was affected by factors,such as sunlight,degree of human disturbance and habitat types.
