应用扫描电镜(SEM)对椰心叶甲啮小蜂Tetrastichus brontispae Ferrière成虫触角感器的超微结构进行观察。结果表明,在触角上共有8种感器,分别为毛形感器、多孔板状感器、刺形感器、锥形感器、耳形感器、乳状感器、腔形感器和Bhm氏鬃毛;其中毛形感器和板形感器是主要感器,数量较多分布较广;雌雄蜂触角有明显的性二型现象,表现为雌雄触角大小不同,触角感器类型、大小、数量、分布不同。
The ultrastructure of the antennal sensilla of Tetrastichus brontispae Ferrière was observed by scanning electron microscopy (SEM). The results showed that there are altogether 8 kinds of sensilla on the antennae, which are wool sensor, perforated plate sensor, prickle sensor, taper sensor, ear sensor, milky sensor, cavity sensor and B hm’s mane; among them, the hairiness sensor and the plate sensor are the main sensors, the number is more widely distributed; the male and female bee antennae have the obvious sex II phenomenon, showing the different male and female antennae, the type of antennae Size, quantity and distribution are different.
