Females of Demotina fasciculata (Coleoptera: Chrysomelidae) were found to prefer to feed on galls induced by Andricus moriokae (Hymenoptera: Cynipidae) rather than on leaves of its host plant, Quercus serrata (Fagaceae). This is the first record of cecidophagy by adult chrysomelid beetles. Demotina fasciculata did not infest healthy galls induced by another unidentified cynipid species on the same host trees, but did feed on galls inhabited by an inquiline species Synergus quercicola (Hymenoptera: Cynipidae), presumably because such galls remained on the host trees longer than healthy galls. Galls of A. moriokae were infested more severely than cynipid galls inhabited by the inquiline. Therefore, higher density and thicker gall wall in A. moriokae galls seem to make them more suitable targets for D. fasciculata to attack. Larval chambers of A. moriokae galls were stripped by the infestation of gall walls and readily dropped to the ground, resulting in 100% death of cynipid larvae due to desiccation, while 62.5% of pupae survived when they had developed to the late stadium before the fall of larval chambers. 相似文献

Three species of Michotamia are recorded from China. Of these Michotamia aurata (Fabricius, 1794) was previously reported from Hainan and Taiwan. Michotamia assamensis Joseph & Parui, 1995 is recorded from China and Laos for the first time, and Michotamia yunnanensissp. n., is described and figured. A key to the known species from China is provided. A new name, Michotamia subnigra, is given to Michotamia nigra Scarbrough & Hill, 2000, which is preoccupied by Michotamia nigra (Meijere, 1911). 相似文献

Several problems in Strobilanthes Blume (Acanthaceae: Ruelliae) are clarified as a result of collaboration between Chinese and western botanists. Examination of pollen has permitted clear delimitation of four morphologically similar species, Strobilanthes szechuanica (Batalin) J. R. I. Wood & Y. F. Deng, S. labordei H. Lév., S. wakasana Wakasugi & Naruhashi and S. wilsonii J. R. I. Wood & Y. F. Deng, the latter described for the first time in this paper, although first collected more than a hundred years ago. A key is provided to help distinguish these species. The globose, echinulate pollen found in several species from China and Japan and assigned to the genus Championella by Bremekamp is shown by SEM photography to be distinct from other pollen hitherto regarded as the same. Three new species, S. abbreviata Y. F. Deng & J. R. I. Wood, S. lihengiae Y. F. Deng & J. R. I. Wood and S. vallicola Y. F. Deng & J. R. I. Wood are described. S. austinii C. B. Clarke ex W. W. Sm. is lectotypified to show that it is conspecific with S. lamiifolia (Nees) T. Anderson, a species demonstrating trans-Himalayan links. New combinations are made for four species as the authors recognize only a single genus, Strobilanthes within the Strobilanthinae as defined by Bremekamp. S. gongshanensis Tsui and S. aenobarba W. W. Sm. are shown to be only varieties of S. inflata T. Anderson. Illustrations are provided for all new species. © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 150 , 369–390. 相似文献

The genus Scoparia from the Hailuogou Glacier area in the south‐eastern fringe of the Tibetan Plateau of south‐western China is studied, nine species are revealed by combining DNA barcoding (658 bp of the mitochondrial gene cytochrome c oxidase subunit I, COI) and morphology. Studies show that Scoparia species from the Hailuogou Glacier area are 37.5% as many as all the previously known congeners in China. Six species are described as new to science: S coparia simplicissima Li sp. nov. , S coparia tribulosa Li sp. nov. , S coparia longispina Li sp. nov. , S coparia gibbosa Li sp. nov. , S coparia globosa Li sp. nov. , and S coparia annulata Li sp. nov. The female of Scoparia metaleucalis is described for the first time herein. All species are either diagnosed or described and illustrated, and a map of China showing the topography and localities where Scoparia species are recorded is also provided, including the species number of all the recorded localities. The results reveal the exceptional species diversity of Scoparia from the Hailuogou Glacier area, as well as demonstrate that the integration of DNA barcoding and morphological approaches is highly effective for indentifying scopariine moths in the Hailougou glacier area. All the studied specimens are deposited in the Insect Museum, Jiangxi Agricultural University, Nanchang, China. © 2014 The Linnean Society of London 相似文献

Abstract.
- 1 Rapid and substantial changes have occurred in the parasitoid and inquiline community associated with the agamic galls of Andricus quercuscalicis since it invaded Britain in the late 1950s. The number of parasitoid and inquiline species has risen from one to thirteen over a 15-year period. Although the number of species has been relatively consistent over the last 8 years, the species composition has changed considerably and in a highly characteristic way during this period.
- 2 The parasitoid complex can be divided into two broadly distinct sets of parasitoid species; one set attacks only the gall former whereas the other set concentrates on the inquilines living in the wall of the gall.
- 3 The most dramatic change, however, is in the abundance of inquilines which were reported to be virtually absent in earlier studies on this community in Britain. Over a period of only 5 years, between 1988 and 1993, inquiline attack rose from less than 0.01 to an average of 0.26 inquilines per gall. The intensity of inquiline attack is geographically heterogenous, with high inquiline numbers restricted to south-east England. Because of the relatively high specificity of the parasitoids, high inquiline abundance is positively correlated with parasitoid species richness in knopper galls.
- 4 Parasitism rates, particularly on the gall former, were generally low (<10%). Over the last 5 years, however, seven parasitoid species have been consistently recorded and the mortality caused by these species has increased continuously. The species composition of the community associated with this alien gall wasp in Britain has quickly converged to the community known from its native range in continental Europe. Parasitoid species known to attack the galls of A.quercuscalisis on the continent have been recorded from it in Britain for the first time mainly in areas where inquilines have recently become abundant.
- 5 Since rates of parasitism of the gall former are still low, parasitoids are unlikely to play a major role in the population dynamics of this invading gall wasp at present, but the rapidly increasing inquiline and parasitoid attack could be a source of increased mortality for native cynipid species which are the alternative hosts of those parasitoid species.

SummaryThe winter stonefly genus Isocapnia Banks, 1938??? is mainly distributed in western North America and eastern Asia, but has never been reported from China. In this paper, we report, describe and illustrate a new species of this genus, I. anguis n. sp. from Sichuan Province of China. This is the first record for the genus Isocapnia from China, extending the distribution of Isocapnia into the southwestern China. An identification key to all the Isocapnia species from Asia is provided.??? 相似文献

Chromosome numbers are given for 16 taxa in Allium Section Allium , three in Section Codonoprasum , two in each of Sections Molium and Rkizirideum and one in each of Sections K'aloprasum, Megaloprason and Melanocrommrum. The basic chromosome number is x = 8 in all except Section Molium , in which the studied species unusually have x = 7. Polyploid) is common in the genus, with over half of the studied taxa in Section Allium having polyploid representatives. The highest ploidy levels found so far in the genus occur in A. dregeanum (2n = 8x = 64 and 10x = 80), which is counted here for the first time. Although highly polyploid, this disjunct South African species forms only bivalents during meiosis. The chiasmata are proximal, an uncommon phenomenon reported also in hexaploid 1. nm-peloprasum. Although A. dregeanum is genetically related to A. ampeloprasum , the suggestion that it is a cultivated variant of that species introduced to South Africa by the early settlers is unlikely. 相似文献
