摘　　要： 准确获得红火蚁Solenopsis invicta Buren发生程度数据是做好防控工作的基础和前提,明确不同调查方法之间的定量关系可为建立该蚁发生程度度量的标准化体系提供依据。本研究比较了应用诱饵诱集法和陷阱法获得的红火蚁工蚁数量,并分析了二者的相关性,建立了模型。累计设置了840个诱饵,共诱集到183753头工蚁;设置840个陷阱,共收集工蚁93787头。一年中不同时期诱饵诱集法采集的工蚁数量以4月-6月最多,为285.8头/诱饵;陷阱法是7月-8月,为171.7头/陷阱。诱集法、陷阱法收集到的工蚁数量极显著相关,描述该关系的6个模型分别为Y=0.2693X+27.9010(1月-3月)、Y=0.2309X+22.6450(11月-12月)、Y=0.2818X+61.1160(4月-6月)、Y=0.6219X+28.1070(7月-8月)、Y=0.3067X+32.2510(9月-10月)、Y=0.3635X+32.2510(1月-12月)。本研究结果对建立红火蚁发生程度主要指标的转换体系具有参考意义。 The data of red imported fire ant Solenopsis invicta Buren infestation is the foundation and prerequisite for preventing and controlling the fire ant, and to reveal the quantitative relations among the infestation data by the different survey methods could provide the basis for establishing the standard indices system of the fire ant infestations. The fire ant workers were collected by the bait trap and pitfall trap in the same area, and the correlation among the workers by the two traps was analyzed, and the relative models were presented. The results showed that the wokers （ 183753 ind. collected by 840 bait traps） were obviously more than those （93787 ind. by 840 pitfall traps）. In a year, they were the most with 285.8 ind./bait for bait trap during April and June, and 171.7 ind./pitfall for pitfall trap during July and August. The workers for the two traps were correlated significantly, and the mathematical equations between bait trap （Y） and pitfall trap （X） were presented as follows： Y =0. 2693X ＋27.9010 （ January - March）, Y = 0. 2309X ＋ 22. 6450 （ November - December）, Y = 0.2818X ＋ 61.116 0 （ April -June）, Y = 0. 6219X ＋ 28. 1070 （July - August）, Y = 0. 3067X ＋ 32. 2510 （September - October）, and Y = 0. 3635X ＋ 32. 251 （ January - December） , respectively. The data in this study would be a reference to establish the unified standard system for the fire ant infestation.
