蚁巢受扰后红火蚁工蚁外出连续性活动的观察

Observation of Continuous Activities of Solenopsis invicta Worker after Disturbance in the Arecanut Plantation

为给红火蚁(Solenopsis invicta)的科学监测和准确防控提供科学依据,本研究采用刻度图示法对海南岛槟榔园生境中的红火蚁工蚁的爬升高度、数量和恢复平静时间等指标进行观察和分析。结果表明,工蚁的数量和爬升高度在受扰后时长到45 s时达到峰值后逐渐降低;通径分析显示受扰后180 s内工蚁在阳面爬升高度与蚁巢体积相关性最高,蚁巢体积和活动测试时长对受扰后15 s工蚁阳面爬升高度、受扰后60 s工蚁阴面爬升高度、受扰后60 s工蚁爬升高度和180 s工蚁爬升高度呈正向促进作用,而蚁巢的高和体积对受扰后60 s工蚁阳面爬升高度呈正向促进作用。

To provide a scientific basis for scientific monitoring and accurate control of Solenopsis invicta,the method of ruler-mark was used to observe and analysis the climbing height,the number of worker ants,and the restore calm time of S.invicta worker in arecanut(Areca catechu L.)plantation of Hainan Island.The results indicate that the number of worker ants and climbing height decreased gradually after reaching the peak at 45 s after being disturbed.Path analysis revealed that climbing height of the sunny side within 180 s of worker ants had the highest correlation with volume of ant nest after being disturbed.The volume of ant nest and the activity test duration positively influenced the climbing height of the sunny side at 15 s of worker ants after being disturbed,the climbing height of the shady side at 60 s of worker ants after being disturbed,the climbing height at 60 s of worker ants after being disturbed,and the climbing height within 180 s of worker ants after being disturbed.Additionally,surface height and volume of ant nest positively influenced the climbing height of sunny side at 60 s of worker ants after being disturbed.
