摘要
为明确入侵性有害生物红火蚁(Solenopsis invicta)在海南省海口市的发生与分布情况,并为下一步的防控工作提供科学依据。本研究应用奥维互动地图(OvitalMap)和大地图(BIGEMAP)结合样方法及踩踏法对海口市管辖区域内不同生境类型红火蚁疫情的发生情况进行了调查。结果表明:全市共有16个乡镇及部分市区有红火蚁的发生。发生程度主要以一级和二级为主,极少数为三级,发生面积为12880.53 m2;4个乡镇为潜在发生点,面积为11600.00 m2。发生率最高的生境类型是乡镇街道(69.23%),其次为城市公园(66.67%)和草地(63.63%)。红火蚁发生程度由靠近港口区域向外逐渐减弱,且呈现向周边地区蔓延扩散趋势。
In order to define the fire ants invasive pest(Solenopsis invicta)occurrence and distribution in Haikou,Hainan Province,and provide scientific basis for the prevention and control work,this study combined OvitalMap and BIGEMAP with quadrat method and walking observation method to investigate epidemic of Solenopsis invicta in Haikou jurisdiction areas at different ecological environments.The results showed that Solenopsis invicta were found in 16 townships and some urban areas.The occurrence degree was concentrated in the first and second level,very few at leve of three,with the total occurrence area of 12880.53 m2.4 townships were potential occurrence areas with the area of 11600.00 m2.The highest incidence habitat type was township streets(69.23%),followed by urban parks(66.67%)and lawns(63.63%).It gradually weakened from the port area,and showes a trend of spreading to surrounding areas.
