孤蜂在生态系统中起着至关重要的作用,有助于作物和野生植物的授粉。所有雌性都是生殖的,它们的栖息地要求包括筑巢地点,食物资源和嵌套材料。尽管这些活动需要能够检测环境中的生物和非生物刺激,这些物种的感官系统研究甚少。在这项研究中,使用扫描电子显微镜研究了属于三个Apoidea科的五个孤立蜜蜂的触角感觉。其中包括两种茎巢蜜蜂,Ceratinacucurbitina(Rossi,1792年)(Apidae)和Osmiascutellaris(Morawitz,1868)(Megachilidae),和三种地面筑巢蜜蜂,Lasioglossumbrevicorne(申克,1870),Lasioglossumleuozonium(Schrank,1781),和Lasioglossumvillosum(Kirby,1802)(卤科)。根据雌性的形态特征,在雌性中鉴定出13种不同类型的触角感:触角感(STI亚型,II,III),chaetica(SchI亚型,II),basiconica(SBI亚型,II,III,IV),胎盘,钟形,Coeloconica,和壶腹.讨论了它们的功能作用,并比较了物种之间以及每个物种的触角片段内的形态。结果为进一步的生理和行为研究提供了基线,以确定触角感觉在栖息地选择中的作用,食物搜索和筑巢地点选择。
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.
