摘要

圈养动物的行为和福利对动物学收藏、圈养繁殖计划、食品生产和伴侣动物饲养者都非常重要。人工照明通常缺乏紫外线波长,在室内动物围栏中使用这种照明可能会对可见紫外线波长的动物的行为和福利产生重大影响。这些动物包括鸟类、爬行动物和鱼类,也包括昆虫。在这里,我们研究了紫外线存在和紫外线不存在的光环境对 Vanessa cardui 行为的影响,Vanessa cardui 是一种蝴蝶,具有许多昆虫典型的三基色视觉系统。我们使用一个分成两半的自由飞行竞技场进行了行为实验,每半竞技场都可以接受紫外线+或紫外线-的光照。当两半竞技场的光照条件相同时,我们发现紫外线+和紫外线-光照环境下的活动没有显著差异。然而,当两个半场的光照条件不同时,蝴蝶对紫外线+半场的偏好明显高于紫外线-半场。即使紫外线+的总体光照强度低于紫外线-的光照强度,情况也是如此。我们的研究结果表明,缺乏紫外线的人工照明条件本身并不会影响蝴蝶的活动,但在有选择的情况下,蝴蝶更喜欢含有紫外线的照明。基于这些发现,可以设计使用辅助照明或滤光器的人工饲养光环境,以改善人工饲养昆虫的福利和游客体验。

Lighting and behaviour in captivity: butterflies prefer light environments containing UV wavelengths

The behaviour and welfare of animals in captivity is of great importance to zoological collections, captive breeding programmes, food production and keepers of companion animals. Artificial lighting is commonly deficient in UV wavelengths, and use of such lighting for indoor animal enclosures could have significant impacts on the behaviour and welfare of animals to which UV wavelengths are visible. This includes birds, reptiles and fish, but also insects. Here we investigated the effect of UV-present and UV-absent light environments on the behaviour of Vanessa cardui, a butterfly that possesses a trichromatic visual system typical of many insects. We conducted behavioural experiments using a free-flight arena divided in half, where each half could be subjected to UV+ or UV− illumination. When lighting conditions for the two arena halves were the same, we found no significant differences in activity between UV+ and UV− light environments. However when lighting conditions for the two arena halves were different, butterflies showed a significant preference for the UV+ over the UV− half. This remained the case even when the overall intensity of UV+ illumination was less than that of UV− illumination. Our results suggest that UV-deficient artificial lighting conditions do not themselves affect the activity of butterflies, but that given a choice, butterflies prefer lighting that contains UV. Based on these findings, captive light environments can be designed that use supplementary lighting or filters to improve the welfare of captive insects, and the visitor experience.

期刊介绍: Growing interest in behavioural biology and the international reputation of Animal Behaviour prompted an expansion to monthly publication in 1989. Animal Behaviour continues to be the journal of choice for biologists, ethologists, psychologists, physiologists, and veterinarians with an interest in the subject.
