摘要
使用扫描电镜系统观察并描述了黄野螟Heortia vitessoides Moore幼虫触角及口器上的感器。黄野螟幼虫的头式为下口式,头上有触角、单眼、感觉刚毛、上唇、下唇、上颚、下颚、吐丝器。幼虫头部下方有1对3节的触角,触角第2节及端节上有5种感器,即毛形感器、短毛感器、锥形感器、栓锥感器及小锥形感器。口器附肢下颚须上有栓锥感器,外颚叶侧壁和外颚叶端部边缘有栓锥感器和锥形感器。下唇须上有锥形感器和栓锥感器各1个。在吐丝器前方有1对锥形感器。
The sensilla on the antennae and mouthparts of larvae of Heortia vitessoides Moore were ob- served and described with scanning electron microscope （ SEM ） . The main results were as follows： 1 ） The head structure type of the larvae was hypognathous. 2） The antennae on the head had 3 seg- ments and 5 kinds of chemoreceptors were found on antennae of the larvae, namely sensilla trichodea （ STI）, short sensilla trichodea （STII） , sensilla basiconica （ SB ）, sensilla styloconica （ SS ） and small sensilla basiconica （ Sb s）. 3 ） maxillary palpus had 3 segments which had 8 styloconic sensilla;galea and labial palpus had basiconic sensilla and styloconic sensilla;a pair of basiconic sensilla located on the front of fusulus.
