中文摘要:
      红火蚁Solenopsis invicta Buren的防御行为是其被认定为社会性昆虫的关键特征之一。红火蚁蚁巢受到侵扰时,工蚁会快速涌出搜寻侵扰物并展开攻击。然而,蚁巢受侵扰后工蚁的行为反应与蚁巢大小和侵扰强度之间的关系有待进一步明确。为此,本研究通过野外视频记录并结合室内统计分析的方法来明确不同大小的红火蚁蚁巢受侵扰后工蚁反侵扰行为的动态过程。结果表明,蚁巢大小和受侵扰强度对蚁巢受侵扰后工蚁的反应速度具有显著影响。同等侵扰强度下,与中、大型蚁巢相比,小型蚁巢的工蚁往往表现出更慢的行为反应。尤其在低侵扰强度时,小蚁巢工蚁的反应时间平均0.8 s,而中蚁巢和大蚁巢均仅为0.34 s。当侵扰强度相同时,蚁巢越大,受侵扰后召集工蚁的数量越多;当蚁巢大小相同时,侵扰强度越高,召集工蚁的数量越多。但无论是蚁巢大小还是侵扰强度的不同,红火蚁蚁巢受侵扰后,召集工蚁的数量到达峰值的时间均为30 s左右。研究结果为进一步了解红火蚁的防御行为,科学预防红火蚁的攻击,以及有效开展红火蚁的防治提供了重要的实验依据。
英文摘要:
      The defensive behavior of Solenopsis invicta Buren workers is one of the key characteristics of its identification as a social insect. When the ant nest is invaded, the worker ants will quickly come out to search for the infestation and attack. However, the relationship between the behavior response of workers and the size of ant nest and the intensity of intrusion needs to be further clarified. To this end, this study used video recording and indoor statistical analysis to understand the dynamic process of anti-infestation behavior of workers after ant nest was invaded. Our results showed that the nest size and infestation intensity significantly affected the reaction rate of workers after ant nest was invaded. At the same intensity of infestation, small nest workers tended to show slower responses than medium and large nests. Especially at low infestation intensity, the average reaction time of workers in small ant nests was 0.8 s, while only 0.34 s was observed in medium and large ant nests. When infestation intensity was the same, the larger the nest, the more workers gathered after infestation. When the nest size was the same, the higher the infestation intensity, the more workers gathered after infestation. However, no matter the size of the nest or the intensity of infestation, after the ant nests were invaded, the time for the number of workers to reach the peak value was about 30 s. Our results provide an important experimental basis for further understanding the defense behavior of S. invicta workers and how to protect people from the attack of them.
