Abstract

In social insects, situations can arise that threaten an individual or an entire colony. When the call for help goes out, different behavioral responses are elicited by signals emitted from nestmates. In ants, the response can be one of redemptive behavior by the worker receiving it. However, little is known about the evolution of this behavior and in which group of ants it manifests. Therefore, this study investigates whether workers of Odontomachus brunneus Patton can act as rescuers, able to detect and respond to calls for help from nestmates. Laboratory experiments were carried out in which the legs of ants were trapped by tape, simulating capture by a predator. Nearby were nestmates able to receive and respond to a request for help. Two experiments were performed: 1. Calls for help were made at different distances, in order to test the response latency. 2. Evaluation of whether rescuers would respond differently to calls for help from nestmates, non-nestmates of the same species, and ants of another species. Finally, evaluation was made of the behaviors of the rescuers when they responded to requests for help from nestmates and ants of another species. It could be concluded from the results that O. brunneus workers respond to signals emitted by workers who may have been captured by a potential predator, prompting the performance of behaviors related to rescue attempts. The signals involved appear to have an optimal range and are species-specific. When exposed to a capture situation, this species transmits audible signals by stridulation, so it is possible that this type of signal may be involved, in addition to chemical signaling.
当被抓到的时候,它们的同伴会请求帮助和照顾吗?
在群居昆虫中,可能会出现威胁到个体或整个群体的情况。当求救信号发出时,同伴发出的信号会引起不同的行为反应。在蚂蚁中,这种反应可能是工蚁接受它的一种救赎行为。然而,人们对这种行为的进化以及它在哪一群蚂蚁中表现出来知之甚少。因此,本研究探讨了斑齿齿鼠工蜂是否具有“救助者”的能力,能够发现并响应同伴的求助。在实验室进行的实验中,蚂蚁的腿被胶带困住,模拟被捕食者捕获。附近是能够接收和响应求助请求的鸟巢。进行了两个实验:1。为了测试响应延迟,他们在不同的距离拨打了求救电话。2. 评估救援者是否会对来自同一物种的巢友、非巢友和另一物种的蚂蚁的求助做出不同的反应。最后,对施救者在回应同伴和其他种类蚂蚁的求助时的行为进行了评估。从结果可以得出结论,O. brunneus工蜂对可能被潜在捕食者捕获的工蜂发出的信号做出反应,促使其做出与救援尝试相关的行为。所涉及的信号似乎有一个最佳范围,并且是物种特异性的。当暴露于捕获情况时,该物种通过鸣叫传递声音信号,因此除了化学信号外,可能还涉及这种类型的信号。

期刊介绍: SOCIOBIOLOGY publishes high quality articles that significantly contribute to the knowledge of Entomology, with emphasis on social insects. Articles previously submitted to other journals are not accepted. SOCIOBIOLOGY publishes original research papers and invited review articles on all aspects related to the biology, evolution and systematics of social and pre-social insects (Ants, Termites, Bees and Wasps). The journal is currently expanding its scope to incorporate the publication of articles dealing with other arthropods that exhibit sociality. Articles may cover a range of subjects such as ecology, ethology, morphology, population genetics, physiology, toxicology, reproduction, sociobiology, caste differentiation as well as economic impact and pest management.
