摘  要：
对寄生蜂交配行为的了解将有助于发展对其行为调控的技术,提高寄生蜂对害虫控制的效能。为探讨椰心叶甲啮小蜂Tetrastichus brontispae Ferri埁re的复眼和触角在交配中的作用,用水溶性黑色素和液体石蜡分别涂抹该蜂复眼和触角后观察其交配行为,并利用扫描电镜(SEM)观察其复眼和触角的超微结构,分析雌、雄蜂触角感器的分布与数量差异。结果表明:椰心叶甲啮小蜂雄蜂的复眼在交配过程中起重要作用,雌蜂复眼作用不显著。在椰心叶甲啮小蜂求偶识别和接受过程中,雄蜂触角柄节部位起主要作用,其次是棒节部位,再次是鞭节的索亚节部位,而雌蜂触角鞭节索亚节部位起主要作用,然后是棒节部位,最后是柄节部位。扫描电镜观察表明椰心叶甲啮小蜂触角上共有8种感器,其中毛形感器和板形感器是主要感器,雌、雄蜂触角有明显的性二型现象,表现为触角大小不同及触角感器类型、大小、数量、分布不同。

摘  要：
Understanding copulation behavior of chalcids can help the development of techniques for manipulating chalcid behavior,and thereby increase the efficacy of chalcids as biological control agents in insect pest management.The effect of compound eyes and antennae on copulation behavior of Tetrastichus brontispae Ferrière was studied by smearing its compound eyes and antennae with water-soluble melanin pigment and liquid paraffin,respectively.The ultrastructure of compound eye and sensilla on antenna of T.brontispae was observed with scanning electron microscope (SEM),and the differences of distribution and quantity of sensilla on antenna of two sexes were analyzed.The results showed that there was a significant difference in the role of the compound eye of the chalcid in copulation behavior between two sexes.The importance of every segment to copulation of male chalcid decreased in the order of antennal scape,antennal club,and antennal flagellum,but for the female the order was antennal flagellum,antennal club,and antennal scape.Eight distinct types of the sensilla were found on antenna with scanning electron microscope.As the major sensilla,both sensillum trichodeum and sensillum placodeum were distributed widely on the antenna.Moreover,there was an obvious sexual dimorphism of antenna of the chalcid as shown by different size of the antenna and different shape,size,number and distribution of the sensilla.
