The location and structures of sex-pheromone-producing gland in female H.insularis were studied by EAG,GC,SEM,and TEM.These studies showed that thegland situate in the intersegmental membrane between the eighth and ninthabdominal segments,and is an eversible abdominal fold;Many plump cones disturbon the surface of the gland.The glandular cells of 2-day old virgin female H.insularis are arranged in one layer,among which the central cells are columnarepithelial cells and flat on two sides.The nucleus is irregular elliptical.There isevident conjugation between cells and the involution is more in the basal membraneof cell.Microvilli are distributed on the cytoplasmic membrane and linked withendocuticle on which there are many layers of chitin,and the outer cuticule is staineddeeper.The cell contains bubbles,mitochondria,glycogen deposits,roughendoplasmic reticulum and smooth endoplasmic reticulum.

动物组织样品在碱性条件下用乙酸乙酯提取，经碳酸钠溶液液-液分配净化，再用硅胶柱固相萃取净化，洗脱液均分成两份后经氮气吹干，分别用双三甲基硅基三氟乙酰氨和七氟丁酸酐衍生，采用选择离子监测模式进行测定，外标法定量。

The two Epistles to the Thessalonians are included among the canonical books accepted by the Councils of the Vatican, of Trent, and of Florence, and are among the homologoumena of all early lists of canonical New-Testament Scriptures; for instance, to mention only such early lists as accord with the received canon of Trent, these two Epistles are listed in the Muratorian Fragment (AD 195-205), in the canons of St.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
