中国蝠螨一新纪录

蝠螨属Spinturnix隶属于蜱螨目Acarina、蝠螨科Spintuaicidae。该属已知约28种,均寄生于蝙蝠体表,我国曾记录8种。1984年5月,在宁夏回族自治区,海原县红羊地区的大耳蝠Plecotus auritus Linnaeus体上采得一种蝠螨,经鉴定为大耳蝠螨,计有3♀♀、3及3若虫。这是我国的首次纪录。 大耳蝠螨的主要特征是背部前足体毛仅有4对,而本属中绝大多数种类,包括我国已有纪录的8种

中国拉绒螨属幼螨一新种(真螨目:约绒螨科)

拉绒螨属(Lassenia)隶于真螨目(Acariformcs)的约绒螨科(Johnstonianidae),1957年由Newell建立。该属在我国尚属初次报导。拉绒螨属的幼螨栖于潮湿环境,寄生于双翅目昆虫体上。根据以下特征可将它与其他约绒螨幼螨区分开来:躯体背面前部的盾板上有较短的前感毛、较长的后感毛、前侧毛和后侧毛各一对;喙有发达的原喙毛、第二喙毛和第三喙毛;基节Ⅱ前方有发育完好的拉氏器(Lassenia-organ);须肢跗节长圆柱形,后方有感棒一根,末端和亚末端各有荆毛一根;跗节Ⅰ和Ⅱ背荆毛基部有伴毛(Companion seta)一根(Newell,1957)。

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
