摘  要  应用扫描电子显微镜观察了美苔蛾Miltochrista miniata和之美苔蛾M. ziczac的触角,发现5种触角感器:毛形感器(3个亚型)、刺形感器、腔锥形感器(2个亚型)、栓锥形感器和Böhm氏鬃毛(2个亚型)。触角感器数量最多的是毛形感器,其次为Böhm氏鬃毛,栓锥形感器的数量最少,其余两种感器数量居中;之美苔蛾的触角感器的总数多于美苔蛾;两种苔蛾雄性个体触角感器的总数均多于雌性个体触角感器的总数。对两种苔蛾触角各感器的形态、分布进行描述,对种间、种内差异进行讨论。

Abstract  Antennal sensilla of Miltochrista miniata andM. ziczac were observed by scanning electron miscroscope. Five types of sensilla were found on the antennae of the studied species: sensilla trichodea (I, II and III), sensilla cheatica, sensilla coeloconic (I and II), sensilla styloconica and Böhm bristles (I and II). The trichodea was the most abundant, followed by Böhm bristles, cheatica and coeloconic, the styloconica was the least. The quantity of antennal sensillaof M. ziczacwas more than that of M. miniata. The number of males’ antennal sensilla of the two lithosiid moths was higher than that of females’. The shape, distribution of sensilla were described, the differences between the sensilla of male and female, M. miniata and M. ziczac were discussed.
