独角仙前翅中的小柱分布及其前翅表面的微细构造

从仿生学的角度,通过研究习行动物翅膀的力学特性,在航天航空业界的构造设计上获得有益的启示。用扫描电子显微镜及爱射光,考察了独角仙前翅的微细构造。结果为考察方法及昆虫形态学,特别是有关独角仙前翅小柱分布及其前翅表面的微细构造方面,亦得到了一些新的见解;1）将甲虫前翅置于透过光下,甲虫前翅上的小柱呈黑点状。用此方法,探明了独角仙前翅中的小柱,除了延气管两侧有点近似直线的排列之外,均为无规律分布,此种分布规律不同于以往所认识的其它种类甲虫所具有特征：小柱以直线分布,并且与小柱对应的前翅表面有凹穴作标记。2）在独角仙前翅内部,存在着肉状（蜂窝状）的构造。此种构造通常在一蜂窝状构造上有1－2上柱,每个蜂窝上小柱根数和蜂窝的大小有关,并且小柱主要分布于蜂窝的角中（蜂窝状构造是航空等许多业界已经广泛采用的工业化了的优良构造,甲虫在此基础上用柱子进行强化,此种强化构造有可能给相关业界的构造设计带来有益的启示。

NUTRITION OF TRIDACHIA CRISPATA (MORCH) (SACOGLOSSA)

Autotrophic nutrition plays an important role in adult Tridachiacrispata in the western Atlantic Ocean and results from an endosymbioticassociation between the sacoglossan and the kleptoplastids ofChlorophyta. A series of living specimens 7-80 mm in length was studied inthe laboratory. After a body length of 10 mm has been attained,the parapodial lobes of the two sides meet and fuse. Microscopicexamination of faecal strings of specimens undergoing this transitionrevealed that algal remains were produced only by juvenilesless than 13 mm long. Larger specimens defaecated only rarelyand the diminutive faecal strings contained no recognizablealgal debris. This transition probably parallels the physiologicaltransition between juvenile heterotrophic nutrition and adultautotrophic nutrition. Microscopic examination of the radulae of transitional specimensshowed no diminution of the size, number or morphology of theteeth. This indicates that in an emergency heterotrophic nutritionmay be resumed. Growth rates of Tridachia were measured in the laboratory, withand without light and the provision of algal foods. Unfed animalslost weight rather rapidly in captivity, whereas those fed uponsuitable algae (Halimeda discoidea, Caulerpa verticillata, C.racemosa and Chaetomorpha sp) did not.Caulerpa sertularioideswas suitable for food for a limited time, but proved toxic afterabout a week. Of the other species tested, Caulerpa verticillatawas the least suitable, while Halimeda, Chaetomorpha and Caulerparacemosa were the best. Ironically, C. verticillata was theonly one of the algal species tested which is known to be takenin the natural diet in Floridean waters. These experiments confirmedthat heterotrophic feeding will be resumed in Tridachia if theculture-conditions do not favour autotrophic nutrition.     

中国甲螨名录(Ⅰ)(蜱螨亚纲:甲螨亚目)

Preface The research on Chinese oribatid mites was started in the 1920's, when A. Jacot recorded 10 oribatid species from Beijing (Peking) and Shandong (Shantung). In the 1980s', Chinese acarologists noticed the necessity of studying soil mites, which were poorly investigated and reported during the past 60 years. Along with the adoption of more open policy in China, the academic exchange and coopera
