摘要

木胡蜂(Sirex noctilio Fabricius)是2013年中国报告的一种主要危害蒙古松的检疫性害虫。逆向化学生态学是控制森林害虫的经典方法,它使用化学诱饵来捕获或阻止昆虫交配。这表明昆虫的感受器在检测外部化学和物理刺激方面起着至关重要的作用。然而,夜蛾触角和产卵器上感受器的分类和分布还不够具体。本文采用扫描电镜(SEM)对夜蛾触角和产卵器上的感受器的超微结构进行了观察。结果表明,雌雄夜蛾触角上的感受器类型和分布一致,分别为毛感器(ST)、毛感器(SC)、Böhm刚毛感器(BB)、基本感器(SB)、壶状感器(SA)和接触化学感受器(CC) 6种。此外,雌性产卵者的感受器有五种类型。除了ST、SC和BB外,还发现了另外两种类型的感觉器:感觉腔(SCa)和感觉腔(SCo)。通过对感受器形态和分布的鉴定,提出不同感受器在夜蛾交配和寄主选择机制中的作用,从而为夜蛾化学通讯研究奠定基础。

Morphology and location of sensilla in the antennae and ovipositor of Sirex noctilio (Hymenoptera: Siricidae)

The woodwasp Sirex noctilio Fabricius is a major quarantine pest that was reported in China in 2013 and mostly damages Pinus sylvestris var. mongolica. Reverse chemical ecology, which uses chemical lures to catch or block insects from mating is the classic way to control forestry pests. This indicates that insect sensilla play a crucial role in detecting external chemical and physical stimuli. Nonetheless, the categorization and distribution of sensilla on the antennae and ovipositor of S. noctilio are insufficiently specific. In this paper, scanning electron microscopy (SEM) was used to observe the ultrastructure of the sensilla of S. noctilio on the antenna and ovipositor. It was found that the types and distribution of sensilla on the antennae of S. noctilio male and female are consistent, and six types of sensilla are found: sensilla trichodea (ST), sensilla chaetica (SC), Böhm bristles (BB), sensilla basiconica (SB), sensilla ampullacea (SA), and contact chemoreceptors (CC). Besides, there are five types of sensilla on the female ovipositor. In addition to ST, SC and BB, two more types of sensilla are also found: sensilla cavity (SCa) and sensilla coeloconica (SCo). Through identification of the morphology and distribution of the sensilla, the functions of different sensilla in the mating and host selection mechanisms of S. noctilio are proposed, thereby establishing a foundation for S. noctilio chemical communication research.

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
