【摘要】 对深圳市红火蚁Solenopsi sinvicta Buren进行种群动态的调查研究,结果表明:6月～10月为红火蚁工蚁活动的盛期,采用诱饵法诱集到的工蚁数量动态有一个明显的高峰期,即7月、8月、9月诱集到的工蚁数量达到最高峰,其中8月虫口密度最大,平均每诱饵上的工蚁数量达到85.01头;6月～10月以及次年2月、3月红火蚁活动蚁巢密度较大,蚁巢密度呈现3峰型,即6月、9月以及次年2月、3月为高峰期。红火蚁工蚁虫口密度与深圳市的月平均气温之间存在极显著的正相关关系。更多还原

【Abstract】 Population dynamics of imported fire ant Solenopsis invicta Buren has been studied for one year in Shenzhen.The results showed that,the worker ants emerged frequently from June to October,the peak of active workers was found in July,August and September,the number of active workers was the largest in August,the average number of workers attracted per bait was 85.01.The active mound density was higher from June to October,February and March in the following year.Three peaks of the active mound density were found in July,September,February and March in the following year.The relationship between the population density of worker ants and the average monthly temperature in Shenzhen were significantly positive correlation.更多还原
