摘  要：
为了解朱红毛斑蛾Phauda flammans(Walker)幼虫头部感受器的种类、分布、数量以及形态特征,利用扫描电镜观察了朱红毛斑蛾幼虫头部形态及触角和口器上的感受器。结果表明,朱红毛斑蛾幼虫头部椭球形,下口式;触角上着生2个毛形感受器、1个刺形感受器和3个锥形感受器;上颚分布有1对刺形感受器和2对栓锥形感受器;下颚分布有1对毛形感受器和1对刺形感受器,下颚须分布有8个锥形感受器;下唇须分布有1个锥形感受器和1个刺形感受器。锥形感受器在朱红毛斑蛾幼虫头部上的分布多而广,在寄主选择时可能发挥关键作用。

摘  要：
In order to clarify the types, number, distribution and morphological characteristics of sensilla on the larval head of Phauda flammans(Walker), the morphology of head and sensilla on antennae and mouthparts were studied using scanning electron microscope. The results showed that the larval head was elliptical and hypognathous. Two sensilla trichodea, one sensillum chaeticum, and three sensilla basiconica were observed on the antenna. Two sensilla chaetica and four sensilla styloconica were found on the mandible, two sensilla trichodea and two sensilla chaetica were found on the maxillae. Eight sensilla basiconica were identified on maxillary palp. One sensillum basiconicum and one sensillum chaeticum were found on labial palpus. Large quantity and widely distributed of sensilla basiconica on the larval head were speculated that they were the crucial sensilla in host selection.
