| 中文摘要: |
| 栗实象Curculio davidi是为害板栗Castanea mollissima的主要种实害虫,严重影响着板栗的品质和产量。为探明栗实象成虫触角感器类型、形态和分布,本文利用扫描电镜对栗实象雌雄成虫触角及触角感器进行观察。结果表明:栗实象雌雄成虫触角柄节、梗节、鞭节1~6亚节长度存在显著差异。雌、雄成虫触角上均有7类12种感器,包括4种刺形感器、2种锥形感器、1种叉形感器、2种毛形感器,1种B?hm氏鬃毛、1种腔形感器和1种端指形感器。其中雄虫刺形感器Ⅰ、毛形感器Ⅰ、叉形感器的长度显著长于雌虫,雄虫鞭节第7、8亚节的锥形感器数量显著多于雌虫。 |
| 英文摘要: |
| Curculio davidi is a major seed pest of chestnut (Castanea mollissima), causing serious damage to both quality and yield of chestnut. To investigate the types, morphology, and distribution of antennal sensilla in C. davidi adults, we used scanning electron microscopy to observe the antennae and antennal sensilla of female and male adults. The results showed that there were significant differences in the length of antennae scape, pedicel and the 1st to the 6th sub segments of flagellum between male and female adults of C. davidi. Seven types and 12 subtypes of common sensilla were identified on the antennae of both genders, including four subtypes of sensilla chaetica, two subtypes of sensilla basiconica, one subtype of sensilla furcatea, two subtypes of sensilla trichodea, one subtype of B?hm bristles, one subtype of sensilla cavity, and one subtype of sensilla finger-like. Among them, the length of sensilla chaetica Ⅰ, sensilla trichodea Ⅰ, and sensilla furcatea in male adults was significantly greater than those in females, and the number of sensilla basiconica in the 7th and 8th segments of the flagellum in male adults was significantly higher than that in females. |
