Abstract

Insects have sophisticated olfactory systems that enable them to detect and respond to complex exogenous chemical cues. The encoding mechanisms of these chemical signals have been studied both in their peripheral and central nervous systems (CNS). While many neuromodulators have been shown to play significant roles in olfactory processing within the antennal lobes of the brain, their roles in peripheral olfactory sensory systems, such as the antennae, are less understood. This review focuses on the role of serotonin (5-HT) receptor in the locust antenna, specifically the modulatory function of the serotonin receptor₂ on odour inputs. We also review recent studies on the modulation of olfaction in the peripheral nervous systems of other insects and discuss potential directions for future research on the role of neuromodulators in insect peripheral olfactory systems.

血清素能调节蝗虫触角的嗅觉处理。

昆虫拥有复杂的嗅觉系统，能够探测复杂的外源化学线索并做出反应。这些化学信号的编码机制已在昆虫的外周和中枢神经系统（CNS）中得到研究。虽然各种神经调节剂已被证明在大脑触角叶的嗅觉处理过程中发挥了重要作用，但它们在触角等外周嗅觉感觉系统中的作用却鲜为人知。这篇综述将重点关注5-羟色胺（5-HT）受体在蝗虫触角中的作用，特别是5-羟色胺受体2对气味输入的调节功能。我们还回顾了最近关于昆虫外周神经系统对嗅觉的调节作用的研究，并讨论了神经调节剂在昆虫外周嗅觉系统中作用的潜在研究方向。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
