In order to provide an scientific basis and technology support to local agricultural by–products export quarantine, an investigation was carried out on the species of stored insects of export agricultural by–products from 2003 to 2005 in the region. The quarantine significance of different stored insects and the insect community structure characteristics of five stored export products were analyzed, besides, a study was conducted on the ecology of Dermestes maculatus Degeer in the laboratory. The main results were as follows. 1. The ordinary and systematic measures were used to investigate stored insect species on export products, such as Willow, Brush, Feather, Leather, Woodwork, grain, coconut funicle, lotus leaf etc., in the finished product, transferring, material reserve and processing storages of the export industries.

为了给该地区农副产品的出口检疫提供科学依据和技术支持，笔者于2003-2005年对江苏沿江地区各类出口农副产品检疫场所的仓储昆虫种类进行了调查，分析了各种仓储昆虫的检疫重要性以及5类出口农副产品仓储昆虫的群落特征，并对重要仓储害虫白腹皮蠹的生态学特性进行了研究，现将结果总结如下： 1、2003-2005年通过对江苏沿江地区的草柳藤制品、笔刷制品、羽绒制品、皮革制品、木制品、粮饲库存点、椰壳纤维、荷叶加工厂等出口企业的成品储藏库、中转库、原料储备库、加工车间等检疫场所的昆虫种类进行了普查和系统调查，共采集标本1800余件，从中鉴定出130种仓储动物，隶属2纲、9目、51科，其中害虫6目、40科、105种，益虫5目、10科、25种；此外，还发现2中国新记录种，即阔鼻谷象Caulophilus oryzae和黑斑豆象Bruchus dentipes。

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.

结合触角电位、毛细管气相色谱、扫描电镜、透视电镜等技术对小线角木蠹蛾雌蛾腹尖末端不同组织部位提取物的测定分析以及腺体位置和形态结构的观察发现：小线角木蠹蛾性信息素分泌腺位于腹部末端8～9节之间，是一个由节间膜特化而成的上皮结构，为一可外翻的腹褶，腺体表面分布着饱满的锥形体，羽化后2天未交尾的雌蛾腺体细胞呈单层排列，腹面中央由密集的柱形上皮细胞组成，细胞排列向两侧延伸至背部，其形状由柱形逐渐变为扁平形，细胞核为椭圆形，细胞与细胞间有明显的胞连接，细胞基底膜基褶较多，质膜上分布着微绒毛，并与内表皮连接，内表皮上有多层几丁质，外角质层染色较深，细胞质中含有空泡、线粒体、脂质粒、粗面内质网和光面内质网。

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。
