六种蜻蜓触角感受器的研究

用扫描电镜研究了６种蜻蜓雌性成虫触角上的感受器，其中差翅亚目：蜻科４种（黄蜻、竖眉赤蜻、秋赤蜻、白尾灰蜻）；束翅亚目：科两种（长叶异痣、二色异痣）。蜻科（Ｌｉｂｅｌｕｌｉｄａｅ．）的４种雌性成虫都具有４种类型的感受器：锥状感受器、腔锥感受器，板状感受器和缶云状感受器。科（Ｃｏｅｎａｇｒｉｄａｅ）的两种雌性成虫具有三种类型的感受器：锥状感受器、腔锥感受器和组合腔锥感受器。这些感受器的数量分布及排列方式在科属之间具明显的区别，同属内种间区别也是明显的；同种内不同性别间的有些种无明显区别，有的种雌性感受器的数量较雄虫多

STUDY ON THE ANTENNAL SENSILLA IN SIX DRAGONFLIES SPECIES(INSECT:ODONATA)

In this paper,the antennal sensilla of 6 species dragonflies belonging to 2 suborders 2 families and 4 genera are studied by SEM method.The specimens are listed as follows:Anisoptera:Libellulidae (Pantala flavescens Fabricius,Sympetrum eroticum Ardens McLanchlan,S.depressiusculum Selys,Orthetrum albistylum Selys);Zygoptera:Coenagriidae Ischnura elegans(Vander Linden). I.lobata Needham].In the female species of Libellulidae there are four types of sensilla,i.e.sensillum basiconicum,sensillum coeloconicum,sensillum placodeum and sessillum ampullaceum.In the female species of Coenagriidae there are mainly three kind of sensilla:sensillum basiconicum,sensillum coeloconicum and sessillum assembly coeloconicum.The number and arrangement of these sensilla are obviously different among the female categories of Libellulidae.
