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。
Knowledge of the behavior of parasitoids mating will help to develop technologies that govern their behavior and increase the effectiveness of parasitoids on pest control. In order to explore the role of compound eyes and antennae in mating of Tetrastichus brontispae Ferriva reed, the mating behavior of compound bees and antennae were observed with water-soluble melanin and liquid paraffin, and their mating behavior was observed by scanning electron microscopy (SEM) And the ultrastructure of the antennae, the female and male wase antennae sensor distribution and quantitative differences. The results showed that the compound eye of Beaver Beetle had an important role in copulation and the effect of compound eye of female wasp was not significant. During the process of identifying and accepting the bee-eaters, the male horns played a major role in the pedicel node, followed by the pedicel part, the serpentine part again, while the female part had the main effect , Then the club section, and finally the handle section. Scanning electron microscopy showed that there were 8 kinds of sensilla on the antennae of Coccinella septempunctata. Among them, the sensilla and the sensillum sensilla were the main sensory organs. Sensor type, size, number, distribution of different.
