| 中文摘要: |
| 本文使用场发射扫描电子显微镜对孟氏隐唇瓢虫Cryptolaemus montrouzieri Mulsant雌雄成虫的触角和触角感受器进行了观察和研究，并对触角形态，感受器形态、类型、数量及分布进行了统计和分析。孟氏隐唇瓢虫雌雄成虫触角均由柄节，梗节及8个鞭小节组成。观察到7种触角感受器：四种锥形感受器（sba），四种刺形感受器（sch），四种毛形感受器（str），一种腔锥形感受器（sco），一种耳形感受器（sau），一种腔形感受器（scl），一种Bhm氏鬃毛（sbm）。毛形感受器和刺形感受器数量最多，其他类型感受器数量都较少。Bhm氏鬃毛只存在于柄节和梗节。第八鞭小节的顶端感受器种类最丰富，被六种感受器稠密覆盖。雌雄触角大小、感受器类型都没有明显差异。根据感受器的分布和以前的相关报道，推测孟氏隐唇瓢虫的毛形感受器可能是信息素接收者，刺形感受器可能是机械性刺激感受器和化学感受器，锥形感受器和腔锥形感受器可能都是植物挥发物接受者，化学和温湿度感受器，耳形感受器或许承担物理或者嗅觉器官的功能，而Bhm氏鬃毛或许能感知触角的位置和活动。 |

| The antennal morphology, sensillar types, quantity and distribution of both sexes of Adult Cryptolaemus montrouzieri Mulsant(Coleoptera: Coccinellidae)was investigated with Field Emission Scanning Electron Microscopy(FESEM).The results show that antenna of adult Cmontrouzieri consists of scape, pedicel, and eight flagellomeresSeven sensillar types are observed: four types of sensilla basiconicae(sba), four types of sensilla chaetica, four types of sensilla trichodea(str), and one type sensilla coeloconica(sco), one sensilla auriciliica(sau), cavity-like sensilla(scs), and Bhm bristle(sbm).Sensilla trichodea are the most numerous; sensilla chaetica are the next most abundantThe number of other sensilla types is greatly reducedOn the tip of the 8th flagellomere, various types of sensilla are densely packed, except for sbmNo remarkable differences are foundin the antennal size, shape, and sensilla types between the male and female of CmontrouzieriAccording to the distribution of sensilla and sensilla functions reported in the past, str are presumed to be pheromone receptors in Cmontrouzieri, sch may function as mechanoreceptors and chemoreceptors,sba and sco are postulated as plant volatiles receptors and chemo-, thermo-, or hygroreceptions, respectively, and sbm may be related to perceiving the antennal position and movement |
