摘要

事实证明,包括昆虫在内的无脊椎动物会表现出各种认知行为和生理现象,这些行为和现象表明它们的内部状态与人类的情绪相似。因此,我们的主要问题是昆虫是否具有这种能力。为了弄清这些问题,我们使用了种甲虫(Callosobruchus maculatus)来研究完全隔离饲养、从未见过其他同种昆虫的行为,并观察它们在短时间(10 分钟)内遇到活的或死的同种昆虫时会做出什么反应,然后将生物参数和交配行为与对照组进行比较。结果表明,与死亡的同类短暂相遇会引起不同性别的生物和行为变化。与交配过一次的雄性和从未见过其他同类的雄性相比,见过其他活的或死的同类但在一生中没有交配过的雄性寿命较短。昆虫不知道的剥夺性生活的危害较小。在雄性昆虫中,性剥夺比感知到的社会剥夺影响更大。相比之下,遇到同类尸体会延长雌性的寿命。在交配前一小时观察到雌性尸体的雄性,当雌性被放入它们的巢穴时,对雌性的关注会减少,雄性的交配潜伏期也会延长。雄性还表现出了恋尸行为。这些结果使我们得出结论,这种昆虫具有某种认知能力,尽管现在下结论还为时过早,还需要更多的研究。

Encountering a dead or live conspecific affects the behavior and longevity of Callosobruchus

Invertebrates including insects have been shown to exhibit a variety of cognitive behaviors and physiological events that indicate interior states similar to human emotion. Therefore, our main question was whether insects have such capacity or not. To shed light on such questions we used the seed beetle Callosobruchus maculatus to investigate the behavior of the insects that were raised in complete isolation and had never seen any other conspecific and to see how they might respond when they encountered their live or dead conspecific for a short time (10 min) and then biological parameters and copulation behaviors were compared with the controls. Results showed that having a brief encounter with a dead conspecific caused different sex-specific biological and behavioral changes. Males who saw another live or dead conspecific and then did not mate during their lifetime had a shorter lifespan than males who mated once and those who had never seen another conspecific at all. A deprivation that insects didn't know about was less damaging. In males, sexual deprivation had a more substantial impact than perceived social deprivation. In contrast, encountering a dead conspecific increased female longevity. Males who observed a dead female body an hour before mating paid less attention to females when a female was put into their niches and male mating latency increased. Males also showed necrophiliac behavior. These results lead us to conclude that this insect experiences some type of cognition although it is too early to conclude in definite and it needs more investigation.

期刊介绍: The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
