| 中文摘要: |
| 为探讨和分析绿翅绢野螟 Diaphania angustalis (Snellen)幼虫头部感器的功能及其作用机制, 通过扫描电镜对其触角和口器上的感器进行了观察。结果表明:绿翅绢野螟幼虫头式为下口式, 头部具有触角、上唇、上颚、下颚和下唇。触角短小, 位于幼虫头部侧下方, 分3节, 其梗节和鞭节分布有4种类型的感器, 即毛形感器、短毛感器、锥形感器和栓锥形感器。口器分为上唇、上颚、下颚和下唇4个部分, 共具有6种类型感器, 分别为毛形感器、刺形感器、指形感器、锥形感器、栓锥形感器和小感觉锥。刺形感器数量较多, 分布范围广, 口器上各部位均有分布; 毛形感器仅分布于上唇; 指形感器仅分布于内唇; 锥形感器仅分布于下颚; 栓锥形感器在下颚和下唇皆有分布; 指形感器为内唇所特有。 |

| To explore the functions of the sensilla on larval head of Diaphania angustalis (Snellen), we examined the ultrastructure of larval head by using scanning electron microscopy (SEM). The main findings were: 1) the head was hypognathous; 2) the antennae were located at lower side of the head with 3 segments and 4 types of sensilla-sensilla trichoidea, short sensilla trichoidea, sensilla basiconica and sensilla styloconica; 3) there were 6 types of sensilla on the mouthparts-sensilla trichoidea, sensilla chaetica, sensilla digitiformia, sensilla basiconica, sensilla styloconica, sensilla of epipharynx and sensory pegs. Sensilla chaetica were abundant and widespread; sensilla trichoidea only occurred on labrum; sensilla digitiformia on epipharynx; sensilla basiconica on maxilla; sensilla styloconica on both maxilla and labium, and sensilla of digitiformia on epipharynx. |
