| 摘 要： | 为进一步了解柑橘木虱Diaphorina citri若虫的优势寄生蜂亮腹釉小蜂Tamarixia radiata的寄生行为，利用扫描电镜对亮腹釉小蜂雌雄成虫触角感受器的种类、分布和形态进行观察。结果表明，亮腹釉小蜂雌成虫触角上存在5种感受器，分别是刺形感受器、毛形感受器、乳头状感受器、板形感受器和末端指形感受器；亮腹釉小蜂雄成虫触角上存在4种感受器，分别为刺形感受器、毛形感受器、乳头状感受器和板形感受器；其中毛形感受器又可以根据外部形态的差异划分为4个亚型，即毛形感受器类型1、2、3、4。此外，板形感受器、毛形感受器类型2和毛形感受器类型3在亮腹釉小蜂雌成虫触角上的分布数量显著多于雄成虫触角上的分布数量。这些形态学差异有助于深入理解不同性别亮腹釉小蜂的触角感知行为。

| Abstract: | To further understand the parasitic behavior of the parasitoid Tamarixia radiata (Hymenoptera:Eulophidae), a dominant parasitic wasp of Asian citrus psyllid Diaphorina citri nymphs, the distribution and morphology of the antennal sensilla of T. radiata were observed with scanning electron microscopy. The results showed that there were five types of sensilla on the antennae of T. radiata female adults, including sensilla chaetica, sensilla trichodea, sensilla mammilliformia, sensilla plate and terminal finger-like sensilla. Moreover, there were four types of sensilla on the antennae of T. radiata male adults, including sensilla chaetica, sensilla trichodea, sensilla mammilliformia and sensilla plate. In addition, sensilla trichodea were further divided into four subtypes based on their differences in external shape, including sensilla trichodea type 1, 2, 3, 4. The numbers of sensilla plate, sensilla trichodea sub-types 2 and 3 were significantly higher on the antennae of T. radiata female adults than on those of male adults. These differences can provide a morphological basis for understanding the antennal perception by different genders of T. radiata. |
