葱黄寡毛跳甲成虫触角的超微形态及感器类型
Morphological Characters of Antenna and Types of Antennal Sensilla of Leaf Beetle Luperomorpha suturalis Chen (Coleoptera:Chrysomelidae)

葱黄寡毛跳甲Luperomorpha suturalis Chen是一种重要的农业害虫，主要危害葱、韭菜等作物。为了明确葱黄寡毛跳甲触角形态及感器类型，利用扫描电子显微镜对其触角进行超微形态观察。结果表明：葱黄寡毛跳甲触角为丝状，由柄节、梗节和包括9亚节的鞭节组成。触角上分布有6种感器，包括刺形感器Ⅰ、刺形感器Ⅱ、Bhm式鬃毛、锥形感器Ⅰ、锥形感器Ⅱ和毛形感器，刺形感器Ⅰ、表皮孔分布于整个触角，刺形感器Ⅱ、锥形感器Ⅰ分布于鞭节，Bhm式鬃毛、表皮附突分布于触角基部，而锥形感器Ⅱ、毛形感器则主要分布于触角端部。雌雄触角除大小外，形态、感器类型和分布均无明显差异。
The fine morphology and distribution of sensilla on Luperomorpha suturalis, which is a significant agricultural pest, were investigated using scanning electron microscopy. Antennae are made up of the scape, pedicel, and nine segment of flagellomeres. Antennae are filiform in shape. Four different sensillar types were distinguished, including two types of sensilla chaetica, two types of sensilla basiconica, sensilla trichodea and bhm bristles. Cuticular pores and appendages of cuticular plates were also found on the antenna. Among them, Sensilla chaeticaⅠ and cuticular pores were distributed on the whole antenna, sensilla chaeticaⅡ and sensilla basiconicaⅠ were found on the flagellomeres, Bhm bristles and appendages of cuticular plates were observed on the base of antenna, sensilla basiconicaⅡ and sensilla trichodea were located on the terminal of antenna.
