红火蚁对无水乙醇的耐受性

Absolute ethanol tolerance of the red imported fire ant, Solenopsis invicta Buren

  • 摘要: 入侵物种对环境的耐受性是其能否成功入侵的重要条件,该研究旨在探讨红火蚁Solenopsis invicta和其他3种蚂蚁对无水乙醇的耐受性的差异. 通过测定4种蚂蚁的致昏迷耗时、亚复苏耗时和全复苏耗时,比较了红火蚁与知本火蚁Solenopsis tipuna、罗思尼斜结蚁Plagiolepis rothneyi和孔氏弓背蚁Camponotus confucii对无水乙醇的耐受性. 结果表明:①4种蚂蚁的致昏迷耗时有显著差异,红火蚁的致昏迷耗时为(99.37±2.56) s,显著长于其他3种蚂蚁;②4种蚂蚁的亚复苏和全复苏比例有显著差异. 红火蚁和罗思尼斜结蚁亚复苏比例分别为81.71%±3.13%和82.89%±0.60%,显著高于知本火蚁和孔氏弓背蚁;红火蚁全复苏比例为80.71%±3.34%,显著高于其他3种蚂蚁,孔氏弓背蚁无法复苏;③3种蚂蚁的亚复苏耗时和全复苏耗时有显著差异,红火蚁和罗思尼斜结蚁亚复苏耗时分别为(155.99±3.89) s和(155.80±3.14) s,显著高于知本火蚁;④红火蚁不同体型工蚁的耐受性有显著差异,大型工蚁的致昏迷耗时为(109.22±3.29) s,显著高于小型工蚁;大型工蚁的亚复苏耗时为(171.23±5.61) s,也显著高于小型工蚁,大、小型工蚁的全复苏耗时无显著差异. 结果表明红火蚁在无水乙醇胁迫下的耐受性显著高于其它蚂蚁. 研究有助于加深对红火蚁入侵能力的理解,为红火蚁的入侵防治提供理论依据.

     

    Abstract: The tolerance of invasive species to the environment is an important condition for their successful invasion. To explore the tolerance of the red imported fire ant Solenopsis invicta to absolute ethanol, the coma time, sub−recovery time and full−recovery time of red imported fire ants and 3 other species of ants (Solenopsis tipuna, Camponotus confucii and Plagiolepis rothneyi) were measured and compared. The results showed that: (1) There was significant difference in the tolerance to absolute ethanol of the 4 species of ants. The coma time of S. invicta was (99.37±2.56) s, significantly longer than the other 3 species. (2) The sub−recovery proportion and full−recovery propotion among the 4 species showed significant difference. The sub−recovery proportion of S. invicta and P. rothneyi was 81.71%±3.13% and 82.89%±0.60%, respectively, significantly higher than that of S. tipuna and C. confucii. The full−recovery proportion of S. invicta was 80.71%±3.34%, significantly higher than the other 3 species. C. confucii could not resuscitate after being soaked in absolute ethanol. (3) Sub-recovery time and full−recovery time showed significant difference between 3 other ant species, the sub−recovery time of S. invicta and P. rothneyi was (155.99±3.89) s and (155.80±3.14) s, respectively, significantly higher than that of S. tipuna. (4) The tolerance between the worker ants of two different sizes of S. invicta was significantly different, the coma time of major workers was (109.22±3.29) s, significantly higher than that of the minor workers; The sub−recovery time of major workers was (171.23±5.61) s, significantly higher than that of the minor workers. It is concluded that the tolerance of S. invicta to absolute ethanol stress was significantly higher than other local ants. This study will help to deepen our understanding of the invasion ability of S. invicta and provide a theoretical basis for the prevention and control of S. invicta.
