本文综述了来自寄主植物的挥发性物质和同种昆虫或异种昆虫释放的各种信息素及两者的协同作用的信息化合物对昆虫行为的影响。特别强调了寄主植物的气味物质和昆虫信息素协同作用在昆虫寻找寄主、求偶、交配及天敌在寄主识别过程中的重要地位。昆虫对寄主植物的识别是由于识别了植物气味的由一定组分、按照严格比例组成的化学指纹图。昆虫信息素与植物挥发性物质相结合为昆虫寻找求偶、交配场所提供更复杂或更全面的信息。许多昆虫只有在寄主植物或寄主植物气味存在时 ,才能释放性或聚集信息素。天敌在寄主识别、搜索及定位等一系列过程中 ,来自寄主的食料、寄主本身及两者的互作的信息化合物起重要的作用。研究信息化合物对昆虫行为的影响可以探索昆虫各种行为的内在机理 ,更好的了解寄主—昆虫—天敌三层营养关系的相互作用。

agricultural Sciences in china 2003年第7期2卷 747-751页

作者： WANG Shao-hua, JI Zhi-jun, LIU Sheng-huang, DING Yan-feng and CAO Wei-xing(Key Laboratory of Crop Growth Regulation , Ministry of Agriculture/nanjing agricultural university ,nanjing 210095, P.R.china) Key Laboratory of Crop Growth Regulation Ministry of Agriculture/Nanjing Agricultural University Nanjing 210095 P.R. China

By removing panicles and spikelets, the effects of nitrogen supply-demand balance(NSDB)on nitrogen translocation and senescence of leaves at different positions of the same stem in rice plant were studied. The results showed that under NSDB0(panicle removal), N accumulation of the top 4 leaves increased significantly, and the leaf senescence process was delayed. The results also indicated that the color of the 4th LFT was mainly affected by NSDB among the top 4 leaves and was lighter than the 3rd LFT when nitrogen supply was insufficient for the sink need.

Spiders are important predators in agroecosystems and contribute to the control of agricultural pest populations. Habitat manage- ment such as the creation of new semi-natural habitats around or within fields enhances spider abundance and species diversity. Using pitfall traps, we investigated the effects of four hedgerow plant species, which serve as undisturbed and permanent semi-natural habitats, on ground-dwelling spider activity density (a parameter of population density and relative activity) and species richness. Samples were collected over two winter wheat and two summer maize growing seasons during 2005-2007 in trial field 1 (slope gradient of 20%) and field 2 (slope gradient of 12%) at the Ziyang Experimental Site in Sichuan Province, china. The hedgerow species evaluated were Amorpha fruticosa (field 1), Vetiveria zizanioides (field 1), Eulaliopsis binata (field 2), and Medicago sativa (field 2). Compared to control plots, hedgerow plots had significantly higher activity density and species richness of ground-dwelling spiders within strips in both fields 1 and 2 during the wheat growing season. The presence of hedgerow strips did not augment the activity density and species richness of ground-dwelling spiders within the crop fields during the wheat or maize growing seasons. The ground-dwelling spider activity density within hedgerow strips was significantly higher in the Vetiveria than in the Amorpha plots and in the Medicago than in the Eulaliopsis plots, and the species richness was significantly higher in the Vetiveria than in the Amorpha plots during the wheat season. Our results suggest that hedgerows may serve as important overwintering sites for ground-dwelling spiders during the wheat growing season. In addition, the diversification of agroecosystems by using hedgerow strips may be a viable strategy for maintaining ground-dwelling spider populations in agricultural areas. However, ground-dwelling spiders did not move into adjacent crop fields; the

AvrXa3: A novel member of avrBs3 gene family from Xanthomonas oryzae pv. oryzae has a dual function

引用

Progress in Natural Science:Materials International 2004年第9期 30-36页

作者： LI Ping*, LONG Juying, HUANG Yingchun, ZHANG Yan and WANG Jinsheng**(Department of plant Pathology, nanjing agricultural university, Key Laboratory of Monitoring and Management of plant Disease and Insects, Ministry of Agriculture, nanjing 210095, china) Department of plant Pathology Nanjing Agricultural University Key Laboratory of Monitoring and Management of Plant Disease and Insects Ministry of Agriculture Nanjing 210095 China

Two positive clones pUAV45 and pUAV47 were identified from the cDNA library of JxoⅢ, a race 3 strain of Xanthomonas oryzae pv. oryzae Dye (Xoo) in Japanese system, using Tn5 based technology. pUAV45 clone contained a 25.4 kb Xoo genomic DNA insert. Southern blot analysis with avrXa 10 as the probe showed that DNA insert in pUAV45 shares homology with avrX 10. Furthermore within the Xoo insert, a smaller 5.7 kb Kpn I fragment (pUAV5k) was identified through hybridization with avrXa 10. The transformation of pUAV45 and pUAV5k into the strain Pxo99 (race 6 in Philippine system) led to the decrease of Pxo99 pathogenicity on rice cultivar Wase Aikoku 3 ( Xa 3) and the increase of the pathogen pathogenicity on Cas209 ( Xa 10). The result of sequence analysis showed that there is a 2598 bp open reading frame (ORF) within the 5.7 kb Kpn 1 fragment (pUAV5k). The ORF shared high identity (97%) with avrXa 10. The deduced sequence of the ORF contained 8.5 tandem repeat units of 34 amino acids, one leucine zipper (LZ), three nuclear localization signal (NLS) motifs, and an acidic activation transcriptional domain (AAD) at C terminus. We named this ORF avrXa 3 and it is classified as a new member of avrBs 3 ( avr/pth ) family with the dual function determined by alternations of avirulence and aggressiveness on rice cultivars carrying different ‘ R ’ genes.

Effect of Pleurotus ostreatus on Dynamics of Meloidogyne arenaria Population and Control Effectiveness

引用

agricultural Sciences in china 2002年第1期1卷 86-95页

作者： XIANG Hong-qiong and FENG Zhi-xin(Department of plant protection , Guizhou university, Guiyang 550025 Laboratory of plant Nematology, South china agricultural university, Guangzhou 510642) Department of plant protection Guizhou University Guiyang 550025 Laboratory of plant Nematology South China Agricultural University Guangzhou 510642

The control effects and application methods of Pleurotus ostreatus on the peanut root-knot nematode disease, Meloidogyne arenaria, were systematically studied in the greenhouse. Results of pot experiments showed that P. ostreatus could effectively reduce the 2nd-instar population density in the soil, and the larva reduced by 80% compared with the control. P. ostreatus could markedly lower the infecting number of the peanut root-knot nematodes, the nematode density inside the root knots declined by 40.00% -82.64%, and the peanut root knots also reduced by 86.96% - 94. 03%. The fungus could defer the initial infection of M. arenaria to the roots, the epidemic rate of the peanut root-knot nematode disease was significantly cut down, and the increase of root-knot changed from the way of Logistic curve in the control to the way of linear curve in the treatment. The final control effectiveness was about 80%. The results of pot trial also indicated that the control effectiveness is closely related to the application time and the amount of this fungus. The key factor affecting control effectiveness was the application time of P. ostreatus in the soil and the suitable time was 20 days before sowing.

A research into the large-scaled spatial forms of cities based on urban design

Science china(Technological Sciences) 2009年第9期52卷 2486-2496页

作者： WANG JianGuo School of Architecture, Key laboratory of Urban and Architectural Heritage Conservation of Ministry of Education, Southeast university, nanjing 210096, china 1. School of Architecture Key laboratory of Urban and Architectural Heritage Conservation of Ministry of Education Southeast University Nanjing 210096 China

In the process of unprecedented urbanization in contemporary china, a great many of Chinese cities have witnessed a rapid expansion of urban scale to different degrees. With the continuous compilation, amendment and enforcement of urban planning, the functional structure, spatial environment, street patterns and textures and even the social aspect of cities have changed conspicuously, all of which have directly happened to the spatial forms of the dimension, or even the multi-dimension of a certain city. By describing and analyzing the structure, evolution and explicit tokens of the spatial forms of cities, this thesis attempts to set up a model of factors that affect urban forms, as well as discuss the attributes, protection, adjustment and development-potential of urban land closely associated with forms. In addition, on the basis of the professional features for urban design to participate in the modeling and construction-management of desirable spatial forms of cities, the author has put forward technical measures for quantitatively appraising and analyzing the large-scaled spatial forms of cities, thus offering technical support to municipal governments and management departments of planned construction.
