同体库蠓幼期的形态(双翅目:蠓科)

同体库蠓Culicoides homotomus Kieffer,1922是马颈盘尾丝虫Onchocerca cervicalis的媒介昆虫,刺叮人类时致病性很强,可引起过敏性休克。本种首先在台湾省发现,解放后证实分布很广遍及全国,是我国的重要吸血蠓种。成虫虽已描述,但幼期尚未见诸记载。掌握幼期形态,不仅是研究种的生物学的必要基础。更是防制措施中,“防小”、“防早”工作中的重要问题。 我们在生活史研究(裘、荣,1974)和孳生地中获得大量的标本。就此作了较为深入的观察和描述,并发现了库蠓幼期过去未曾报道过的一些结构。文内幼虫构造名称以Lawson,1951;JoblirLg,1953为主要依据。蛹结构命名和本文观察方法与台湾铗蠓相同(裘、荣,1980)。

台湾铗蠓多次取食习性的观察(双翅目:蠓科)

吸血双翅目昆虫取食习性的研究,在蚊科和蚋科中广泛开展,但在吸血蠓类却做得很少。在工作中我们发现台湾铗蠓Forcipomyia(Lasiohelea)faiwana(shiraki)在一个生殖营养环内具有多次取食的习性。这种习性,特别足二次取食之间间隔很短的情况,可能会机械传播病原体,故有流行病学意义。现报道如下。

我国东北九种库蠓蛹的形态记述(双翅目:蠓科)

库蠓属(Culidoices Latreille)幼期形态的矿究早已为国外学者所注意,自Goetghebuer(1919)描述了Culicoides pulicaris幼虫以来已有70余种库蠓幼期形态研究的报道。国内裘明华、荣云龙(1981)对同体库蠓(Culicoides homotmus)的幼期形态作了详细描述。这些研究大大丰富了库蠓幼期的生物学。

脉红螺为雌雄异体。雄性生殖系统包括8部分:精巢、输精小管、贮精囊、输精管、前列腺、输精管外套段Ⅰ、输精管外套段Ⅱ和阴茎。雌性生殖系统包括7部分:卵巢、输卵小管、输卵管Ⅰ段、纳精囊、输卵管Ⅱ段、蛋白腺和产卵器。 脉红螺精子形成过程中有精子细胞团形成。精子线形,由头段、中段和尾段构成。头段核基部内凹形成倒“U”形管;中段有丝状线粒体鞘,螺旋缠绕轴丝;尾段由9条粗纤维包围‘9+2’型轴丝构成。 本文亦对前列腺、蛋白腺及蛋白质卵黄粒等的超微结构作了观察。     

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
