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。
Accurately obtaining the data of the occurrence degree of Solenopsis invicta Buren is the basis and premise of prevention and control work. It is clear that the quantitative relationship among different survey methods can provide the basis for establishing a standardized system for measuring the occurrence degree of the ants. In this study, we compared the number of workers of Solenopsis invicta, which were obtained by decoys and traps, and analyzed their correlation and established the model. A total of 840 baits were set up to trap a total of 183,753 worker ants; 840 traps were set up to collect 93,787 worker ants. The number of worker ants collected by bait trapping method in different periods of the year was the highest in April-June, which was 285.8 heads / bait. The trap method was 171.7 heads / trap in July-August. The six models describing the relationship were Y = 0.2693X + 27.9010 (January-March), Y = 0.2309X + 22.6450 (November-December) Y = 0.2818X + 61.1160 (April-June), Y = 0.6219X + 28.1070 (July-August), Y = 0.3067X + 32.2510 (September-October), Y = 0.3635X + 32.2510 (January-December). The results of this study have reference significance for the establishment of the conversion system of the main indicators of the occurrence of red imported fire ant.
