以扫描电镜观察到松毛虫赤眼蜂(Trichogramma dendrolimi)触角板状感器呈穹形长板状隆起在触角的表面.在透射电镜下感器的横切面是一个角质多孔的长圆顶结构,两侧的角质内陷而将感器分成一个中央管和两个侧管.中央管较短,宽为0.7微米,而侧管不明显.树状突远端部分的少量分枝在中央管内成纵行排列,继而分出大量分枝到达圆顶的顶部,每一分枝中包含一根神经小管.感器外部的角质孔板厚为0.19—0.25微米,嗅孔细管位于孔室中,它和树状突分枝的膜相接触.板状感器由神经细胞体、树状突的近端部、纤毛区、树状突的远端部及其分出的分枝等组成.树状突的远端部分横过感器的纵轴呈90°角进入中央管,其分枝到达感器圆顶的顶部.从超微结构研究,它有嗅孔细管存在,说明板状感器有嗅觉作用. 相似文献

The investigation of the antennae of Scutigera coleoptrata (Linnaeus, 1758) by scanning electron microscopy (SEM) revealed the presence of five types of sensilla: sensilla trichodea, beak‐like sensilla, cone‐shaped sensilla brachyconica on the terminal article, sensory cones at the antennal nodes, and the shaft organ. Alongside the presence and absence of antennal sensillar types, three unique characters were found in the Scutigeromorpha: the presence of long antennae with nodes bearing sensory cones, the presence of a bipartite shaft including the shaft organ, and the presence of beak‐like sensilla. Neuroanatomical data showed that the animals' brains are equipped with well‐developed primary olfactory and mechanosensory centers, suggesting that the antennae must be equipped with specialized sensilla to perceive chemosensory and mechanosensory cues. With the evidence provided in this article for the Scutigeromorpha, SEM data are available at last on the antennal sensilla for all five chilopod taxa, allowing a comparative discussion of antennal morphology in Chilopoda.

The sensilla type, number and distribution in male and female adults of Carabus elysii Thomson, 1856 (Coleoptera: Carabidae) were studied using scanning electron microscopy. The results showed that there are seven categories and 12 types of sensilla in C. elysii adults: three types of S.Ch, three types of S.T, two types of S.B and one each of B.B, S.Co, S.Ca and S.Cam. There is no difference between male and female in the types of sensilla. Apart from the significant difference in the number and distribution of S.B.2, S.Co and S.Ca between male dorsal and ventral surfaces, there are no significant differences between male and female antennae. In general, the number of sensilla in females is larger than that in males. The results provide a basic reference for future ultrastructure, electrophysiological, and comparative behavioral studies of Carabus species. 相似文献

该文对桃蚜Myzus persicae(Sulzer)各型触角感器进行了比较研究。扫描电镜观察结果表明桃蚜具有钟形感器、毛形感器、原生感觉圈和次生感觉圈4种类型的触角感器。桃蚜各型触角感器的最大差异主要表现在次生感觉圈上,雄蚜、雌性母和有翅孤雌蚜具有次生感觉圈,雌性蚜、干母和无翅孤雌蚜无;但雄蚜具有的次生感觉圈数目多于雌性母和有翅孤雌蚜,且不仅仅分布在触角第3节,第4、5节也有分布。本文探讨了桃蚜触角感器在化学生态学上的功能作用,各型触角感器的差异与桃蚜寄主选择、迁移及交配行为的关系,并进一步分析了桃蚜触角感器的性二型现象。 相似文献

Gasterophilus nigricornis (Loew) (Diptera: Oestridae) is one of the most damaging obligate parasites of equids in Kalamaili, Xinjiang, China. The main olfactory organs of this stomach bot fly are paired antennae that bear microscopic sensillar structures. The external morphology of the antennal funiculus and sensilla of male G. nigricornis were studied using stereopic microscopy and scanning electron microscopy. A cross-sectional view of the funiculus shows it to be triangular, with an anterodorsal surface, a dorsolateral margin and a posteroventral surface. Almost the entire surface of the funiculus is densely covered with microtrichiae. Small patches lacking these microtrichiae appear as depressions or pits in the surface of the funiculus. Six distinct types of sensilla are recorded, including one trichoid, three basiconic, one auriculate and one clavate sensilla. Trichoid sensilla are the most abundant, followed by the basiconic, auriculate and clavate types in descending order. Only auriculate sensilla are found in pits on the funiculus. Distributions of different sensilla types located on the antennal funiculus are provided. These results are compared with equivalent findings in several other fly species. In addition, the possible functions of the various sensilla types are discussed. 相似文献
