昆虫是一个令人惊讶的成功和多样化的群体，占据了各种栖息地和生活方式的生态位。它们代表了地球上所描述的绝大多数物种和陆地动物的总生物量。它们的成功在一定程度上要归功于它们复杂的视觉系统，包括驱动各种复杂行为的色觉。然而，大多数关于昆虫视觉的研究只集中在少数几种模式生物上，包括苍蝇、蜜蜂和蝴蝶。对植食性昆虫的研究尤其不足，例如小蓟马(Thysanoptera)，尽管它们对农业造成了破坏。尽管蓟马的眼睛很小，但它们表现出强大但可变的颜色特异性反应，但人们对它们视觉系统的生理和生态基础知之甚少。在这里，我们回顾了已知的关于蓟马的视觉行为信息，以及关于它们眼睛的少数生理研究。眼睛结构、光谱敏感度、视蛋白基因和某些小眼中可能存在的滤色器强烈暗示着动态视觉能力。最后，我们讨论了在更好地理解蓟马视觉系统方面仍然存在的主要知识差距，以及为什么弥合这些差距对于扩大对这些微小昆虫应用有害生物管理策略的新可能性是重要的。这篇文章是《理解颜色视觉：节肢动物的分子、生理、神经和行为研究》主题的一部分。
Insects are an astonishingly successful and diverse group, occupying the gamut of habitats and lifestyle niches. They represent the vast majority of described species and total terrestrial animal biomass on the planet. Their success is in part owed to their sophisticated visual systems, including colour vision, which drive a variety of complex behaviours. However, the majority of research on insect vision has focused on only a few model organisms including flies, honeybees and butterflies. Especially understudied are phytophagous insects, such as diminutive thrips (Thysanoptera), in spite of their damage to agriculture. Thrips display robust yet variable colour-specific responses despite their miniaturized eyes, but little is known about the physiological and ecological basis of their visual systems. Here, we review the known visual behavioural information about thrips and the few physiological studies regarding their eyes. Eye structure, spectral sensitivity, opsin genes and the presence of putative colour filters in certain ommatidia strongly imply dynamic visual capabilities. Finally, we discuss the major gaps in knowledge that remain for a better understanding of the visual system of thrips and why bridging these gaps is important for expanding new possibilities for applied pest management strategies for these tiny insects. This article is part of the theme issue ‘Understanding colour vision: molecular, physiological, neuronal and behavioural studies in arthropods’.
