本文对赞青尺蛾属Xenozancla Warren, 1893进行研究,重新描述了属、种特征,总结了属的鉴别特征;描述了种内雄外生殖器的变化并附图,提供了成虫形态、外生殖器图。提出银尺蛾属Yinchie Yang, 1978和枣灰银尺蛾Y. zaohuiYang, 1978 分别是赞青尺蛾属Xenozancla 和赞青尺蛾X. vericolor Warren 的新异名,并为赞青尺蛾X. vericolor Warren指定了选模。同时,采用临近距离平均法(mean propinquity method)结合GIS技术绘制了赞青尺蛾属分布格局图,并据此分析了其分布格局和分布特点,结果表明:该属为亚洲东部特有属,呈西南 华北走向;它在中国华北、华中、西南地区至印度可能存在一个连续的分布区,其分布格局应属于东洋界的东南亚热带-亚热带型。  相似文献

马尾松点尺蛾AbraxasflavisinuataWarren又称松尺蠖,属鳞翅目尺蛾科。该虫于1993年8月在我县国有戴公山、丫山两林场和所属的工山、三里、何湾镇等8个乡村林场首次大发生。由于该虫幼虫生活隐蔽,不易被人发现,被害松树常因虫口密度高,幼虫食量大,成虫繁殖能力强,危害严重。我们于1994-1997年10月进行了生物学特性观察及防治试验,现将初步结果报道如下。1发生与危害林地地处长江以南,北纬30°42’~31°12’,东经117°57’~118°28’范围内。南陵县位于北亚热带湿润…  相似文献

雅尺蛾属 Apocolotois 1936年由Wehrli定名,属古北界分布,世界共记录3种:斑雅尺蛾A. arnoldiaria, 二白点雅尺蛾A. smirnovi, 短瓣雅尺蛾A. almatensis。本文记述了所有种类,其中A. almatensis 为中国新记录种;修订了国内部分研究,双珠雅尺蛾Chariaspilates shuangzhu Yang被确定为二白点雅尺蛾A. smirnovi的新异名;重新归纳了属的特征并编制了分种检索表;附所有种类的成虫及外生殖器图。所见标本均为雄性,猜测雌蛾可能无翅。对该属及所含物种的动物地理特征进行了初步分析。  相似文献

Comprises species occurring mostly in subtidal habitats in tropical, subtropical and warm-temperate areas of the world. An analysis of the type species, V. spiralis (Sonder) Lamouroux ex J. Agardh, a species from Australia, establishes basic characters for distinguishing species in the genus. These characters are (1) branching patterns of thalli, (2) flat blades that may be spiralled on their axis, (3) width of the blade, (4) primary or secondary derivation of sterile and fertile branchlets and (5) position of sterile and fertile branchlets on the thalli. Application of the latter two characters provides an important basic method for separation of species into three major groups. Osmundaria , a genus known only in southern Australia, was studied in relation to Vidalia , and its separation from the Vidalia assemblage is not accepted. Species of Vidalia therefore are transferred to the older genus name, Osmundaria. Two new species, Osmundaria papenfussii and Osmundaria oliveae are described from Natal. Confusion in the usage of the epithet, Vidalia fimbriala Brown ex Turner has been clarified, and Vidalia gregaria Falkenberg, described as an epiphyte on Osmundaria pro/ifera Lamouroux, is revealed to be young branches of the host, Osmundaria prolifera.  相似文献

Fifteen chromosome counts of six Artemisia taxa and one species of each of the genera Brachanthemum, Hippolytia, Kaschgaria, Lepidolopsis and Turaniphytum are reported from Kazakhstan. Three of them are new reports, two are not consistent with previous counts and the remainder are confirmations of very scarce (one to four) earlier records. All the populations studied have the same basic chromosome number, x = 9, with ploidy levels ranging from 2x to 6x. Some correlations between ploidy level, morphological characters and distribution are noted.  相似文献

Curcumin is the yellow pigment of turmeric that interacts irreversibly forming an adduct with thioredoxin reductase (TrxR), an enzyme responsible for redox control of cell and defence against oxidative stress. Docking at both the active sites of TrxR was performed to compare the potency of three naturally occurring curcuminoids, namely curcumin, demethoxy curcumin and bis-demethoxy curcumin. Results show that active sites of TrxR occur at the junction of E and F chains. Volume and area of both cavities is predicted. It has been concluded by distance mapping of the most active conformations that Se atom of catalytic residue SeCYS498, is at a distance of 3.56 from C13 of demethoxy curcumin at the E chain active site, whereas C13 carbon atom forms adduct with Se atom of SeCys 498. We report that at least one methoxy group in curcuminoids is necessary for interation with catalytic residues of thioredoxin. Pharmacophore of both active sites of the TrxR receptor for curcumin and demethoxy curcumin molecules has been drawn and proposed for design and synthesis of most probable potent antiproliferative synthetic drugs.  相似文献

正Dear Editor,In December 2019, a novel human coronavirus caused an epidemic of severe pneumonia(Coronavirus Disease 2019,COVID-19) in Wuhan, Hubei, China(Wu et al. 2020; Zhu et al. 2020). So far, this virus has spread to all areas of China and even to other countries. The epidemic has caused 67,102 confirmed infections with 1526 fatal cases  相似文献
