Abstract

Solitary bees play a crucial role in ecological systems, contributing to the pollination of crops and wild plants. All females are reproductive, and their habitat requirements include nesting sites, food resources and nesting materials. Although these activities require the ability to detect biotic and abiotic stimuli in the environment, the sensory system of these species is poorly studied. In this study, the antennal sensilla of five solitary bee species belonging to three Apoidea families were investigated using scanning electron microscopy. These included two species of stem-nesting bees, Ceratina cucurbitina (Rossi, 1792) (Apidae) and Osmia scutellaris (Morawitz, 1868) (Megachilidae), and three species of ground-nesting bees, Lasioglossum brevicorne (Schenck, 1870), Lasioglossum leucozonium (Schrank, 1781), and Lasioglossum villosulum (Kirby, 1802) (Halictidae). Thirteen different types of antennal sensilla were identified in females based on their morphological characteristics: sensilla trichodea (subtypes STI, II, III), chaetica (subtypes SchI, II), basiconica (subtypes SBI, II, III, IV), placodea, campaniformia, coeloconica, and ampullacea. Their functional role was discussed and morphology was compared among the species and within the antennal segments in each species. The results provide a baseline for further physiological and behavioural studies to determine the role of antennal sensilla in habitat selection, food search and nesting site selection.

五种单蜂(膜翅目,Apoidea)触角感觉器的形态和分布。
独居蜜蜂在生态系统中发挥着至关重要的作用,为农作物和野生植物授粉。所有雌蜂都具有生殖能力,它们对栖息地的要求包括筑巢场所、食物资源和筑巢材料。虽然这些活动需要探测环境中生物和非生物刺激的能力,但对这些物种的感觉系统研究甚少。本研究利用扫描电子显微镜对属于三个Apoidea科的五个独居蜂种的触角感觉器进行了研究。这些物种包括两种茎巢蜜蜂:Ceratina cucurbitina (Rossi, 1792) (Apidae) 和 Osmia scutellaris (Morawitz, 1868) (Megachilidae) 以及三种地巢蜜蜂:Lasioglossum brevicorne (Schenck, 1870), Lasioglossum leucozonium (Schrank, 1781) 和 Lasioglossum villosulum (Kirby, 1802) (Halictidae) 。根据雌性触角感觉器的形态特征,确定了 13 种不同类型的触角感觉器:毛状感觉器(STI、II、III 亚型)、皴裂感觉器(SchI、II 亚型)、基本感觉器(SBI、II、III、IV 亚型)、placentodea、campaniformia、coeloconica 和 ampullacea。对它们的功能作用进行了讨论,并比较了不同物种之间以及每个物种触角节内的形态。研究结果为进一步的生理和行为研究提供了基础,以确定触角感觉器在生境选择、食物搜寻和筑巢地点选择中的作用。

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.
