中文摘要:

鳞翅目是昆虫纲第二大目,包括蛾类和蝶类,很多种类都是重要农林害虫,如小菜蛾Plutella xylostella、棉铃虫Helicoverpa armigera、美国白蛾Hyphantria cunea等,由于它们已经对多种化学杀虫剂产生了较高的抗性,急需开发新的防治手段。近年来,基于昆虫嗅觉行为调控的防控技术被认为是绿色可持续的新方法,已引起广泛关注。昆虫嗅觉在求偶、寻找寄主和产卵场所及躲避天敌等过程中起重要作用,深入探索昆虫的嗅觉感受机制,将为研发高效的嗅觉行为调节剂提供新的思路和参考。本文综述了近4年鳞翅目昆虫嗅觉外周神经感受分子机制的研究进展,涉及的嗅觉基因有气味结合蛋白(Odorant binding protein,OBP)、化学感受蛋白(Chemosensory protein,CSP)、感觉神经元膜蛋白(Sensory neuron membrane protein,SNMP)、气味受体(Odorant receptor,OR)、离子受体(Ionotropic receptor,IR)和气味降解酶(Odorant degrading enzyme,ODE),并展望了未来的研究方向。

英文摘要:

Lepidoptera is the second largest order of Insecta, including moths and butterflies. There are also many pests harmful to agriculture and forestry, such as Plutella xylostella, Helicoverpa armigera, Hyphantria cunea, and etc. Because they have developed high resistance to a variety of chemical pesticides, thus novel pest control measures are urgently needed. In recent years, the technology based on the regulation of insect olfactory behavior has been regarded as a novel green and sustainable pest control approach, which has attracted widespread attention. Insect olfaction plays a crucial role in seeking hosts, courtship, finding suitable oviposition sites, and avoiding natural enemies. Further exploring the olfactory mechanism of insects will provide a new idea and reference for the development of efficient olfactory behavior regulators. This paper mainly reviews the research progress of the molecular mechanism of olfactory perception on peripheral level in Lepidoptera insects in recent four years, including several important genes: odorant binding proteins (OBPs), chemosensory proteins (CSPs), sensory neuron membrane proteins (SNMPs), odorant receptors (ORs), ionotropic receptors (IRs) and odorant degrading enzymes (ODEs). Furthermore, the future research direction is prospected.
