为了更好地了解蓟马如何检测和接收种内和种间通信，宿主选择和交配的信息化学物质，扫描电子显微镜被用来检查和比较的外部形态，分布和超微结构的触角感器在三个苜蓿喂养的蓟马种，Odontothrips loti，Megalurothrips distalis，Sericothrips kaszabi。触角感器有9种主要类型，它们在形态和分布上具有相似性。然而，触角感器的长度和数量的差异也被发现之间的男性和女性的个人和物种。因此，本研究拓展了对缨翅目昆虫（特别是圆尾亚目昆虫）触角感受器形态的认识，为探索蓟马嗅觉机制奠定了形态学基础。蓟马是苜蓿的重要害虫。与许多其他以植物为食的昆虫类似，蓟马依靠触角接收环境中的化学信号来定位它们的宿主。以往的研究表明，昆虫触角表面不同形状的感受器在信号识别中起着重要的作用。然而，形态学分析的触角感器在缨翅目一直局限于只有少数物种。为了进一步了解蓟马触角感器与信息化学物质检测的关系，采用扫描电镜（SEM）对三种蓟马（齿蓟马（Odontothrips loti）、远侧巨蓟马（Megalurothrips distalis）和卡氏绢蓟马（Sericothrips kaszabi））触角感器的形态和分布进行了比较研究。这三种昆虫触角均由8节组成，触角感受器类型相似，在各节中的分布相似，但数量上存在两性二型性。具体而言，总共发现了9种主要类型的感器，包括3种类型的锥形感器（SBI、SBII和SBIII），2种类型的刺形感器（SCh I和SCh II），以及腔锥形感器（SCo）、锥形感器（ST）、钟形感器（SCa）和腔感器（SCav）各一种类型。结合前人的研究结果，探讨了感器的潜在功能，为研究三种蓟马的嗅觉机制奠定了形态学基础。
To better understand how thrips detect and receive semiochemicals for intra- and interspecific communication, host selection, and mating, scanning electron microscopy was used to examine and compare the external morphology, distribution, and ultrastructure of the antennal sensilla in three alfalfa-feeding thrip species, Odontothrips loti, Megalurothrips distalis, and Sericothrips kaszabi. Nine major types of antennal sensilla were identified with similar morphology and distribution pattern among these thrip species. However, differences in the length and number of antennal sensilla were also found between male and female individuals and between species. Therefore, this study expands the understanding on the morphology of antennal sensilla in Thysanoptera (especially the suborder Terebrantia) and lays a morphological foundation for exploring the olfactory mechanism in thrips. Thrips are important pests to alfalfa Medicago sativa. Similar as many other plant-feeding insects, thrips rely on the antennae to receive chemical signals in the environment to locate their hosts. Previous studies indicated that sensilla of different shapes on the surface of insect antenna play an important role in signal recognition. However, morphological analysis of the antennal sensilla in Thysanoptera has been limited to only a few species. To expand the understanding of how antennal sensilla are related to semiochemical detection in thrips, here we compared the morphology and distribution of antennal sensilla in three thrip species, Odontothrips loti, Megalurothrips distalis, and Sericothrips kaszabi, by scanning electron microscope (SEM). The antennae of these three species are all composed of eight segments and share similar types of sensilla which distribute similarly in each segment, despite that their numbers show sexual dimorphism. Specifically, nine major types of sensilla in total were found, including three types of sensilla basiconica (SBI, SBII, and SBIII), two types of sensilla chaetica (SChI and SChII), and one type for each of sensilla coeloconica (SCo), sensilla trichodea (ST), sensilla campaniformia (SCa), and sensilla cavity (SCav). The potential functions of sensilla were discussed according to the previous research results and will lay a morphological foundation for the study of the olfactory mechanism of three species of thrips.
