摘　　要：为了解草地贪夜蛾Spodoptera frugiperda(Smith)幼虫头部感受器的种类、形态、分布和数量,利用FlexSEM-1000型扫描电镜观察了草地贪夜蛾5龄幼虫头部、触角和口器,明确了头部超微形态特征及感受器种类、分布及数量。该虫5龄幼虫头部共有4种类型感受器,分别为毛形感受器(ST)、刺形感受器(SC)、锥形感受器(SB)和栓锥形感受器(SS),其中触角上着生2个锥形感受器、1个刺形感受器、1个毛形感受器和1个栓锥形感受器;左上颚和右上颚各分布有1对刺形感受器;下颚及下颚须上共分布有2个毛形感受器、2个刺形感受器和2个栓锥形感受器;下唇须上有2个刺形感受器;在吐丝器前方两侧有1对刺形感受器。In order to clarify the characters of type,distribution and number of sensilla on the head of larval fall armyworm,Spodoptera frugiperda ,the ultrastructure of head shape and sensilla on 5 th instar larval antennae and mouthparts of S .frugiperda were observed with scanning electron microscope.The results showed that there are four types of sensilla on the head of 5 th instar larvae of S .frugiperda ,named sensillum trichodeum,sensillum chaeticum,sensillum basiconicum and sensillum styloconicum.Two sensilla basiconica,one sensillum chaeticum,one sensillum trichodeum and one sensillum styloconicum were observed on the antenna.Two sensilla chaetica were found on the mandible,and two sensilla trichodea,two sensilla chaetica,two sensilla styloconica were found on the maxilla and maxillary palpus.Two sensilla chaetica were found on labial palpus,and two sensilla chaetica were found on the front of each sides of fusula.
