Evaluation of Beauveria bassiana （Hyphomycetes） isolates as potential agents for control of Dendroctonus valens

引用

Insect Science 2011年第2期18卷 209-216页

作者： Long-wa Zhang Yu-Jun Liu Jian Yao Bin wa.g bo Huang Zeng-Zhi Li Mei-Zhen Fan Jiang-Hua Sun Anhui Provincial Key Laboratory of Microbial Pest Control Anhui Agricultural University Heifei Anhui Entry-Exit Inspection and Quaran- tine Bureau Hefei State Key Laboratory of Integrated Management Agricultural Pest & Rodents Institute of Zoology Chinese Academy of Sciences Beijing China

The red turpentine beetle （RTB）, Dendroctonus valens LeConte, as a destructive invasive pest, has become one of the most economically important forest pest in China. Effective control measures are desperately needed. Entomopathogenic fungi, such as Beauveria bassiana, have shown great potential for the management of some bark beetle species. In this study, 12 isolates of B. bassiana from bark beetle were examined for biological characteristics and virulence, to assess their potential as biocontrol agents for RTB. There were significant differences （at P = 0.05） in colony growth rate, conidial yield, conidial germination, tolerance to UV light and extracellular proteases activity among the tested B. bassiana isolates. Isolates, including Bbl801, Bb1906, Bb789 and Bb773, exhibited the best characteristics, because they have faster hyphal growth rate, higher spore production and faster spore germination, higher UV tolerance and protease （Prl） production. The results of a pathogenicity test ofB. bassiana on RTB larvae showed that most isolates of B. bassiana have demonstrated high efficacy and the highest virulent isolate was Bb 1801, which killed 100% of the treated insects and had a median lethal time （LT50） of 4.60 days at a concentration of 1 ×107 conidia/mL. Therefore, isolate Bb1801 has a great potential for sustainable control of RTB in the forest. The correlation between biological characteristics and virulence of the fungal isolates is discussed and the possibility of combination of entomopathogenic fungi with semiochemicals, as one of the promising strategy for RTB control, is considered.

Quantitative comparisons between relaxation enhanced compressed sensing 3D MERgE and conventional 3D MERgE for vessel wall imaging in equal scan time: preliminary studies

In this study, we quantitatively compared relaxation enhanced compressed sensing(RECS-3D MERgE) with conventional 3D MERgE techniques on blood suppression efficiency, wall-lumen contrast and plaque burden measurement for carotid atherosclerotic imaging in equal scan time. Twelve patients were recruited in the study. RECS-3D MERgE and conventional 3D MERgE were implemented. 2D DIR-FSE was carried out as a reference standard. The lumen signal-to-tissue ratio(STR) was used as the quantitative measure of blood suppression efficiency. The contrast-to-tissue ratio(CTR) was used as the quantitative measure of wall-lumen contrast. Vessel lumen area(LA) and wall area(wa) were measured for morphological comparisons. The lumen STR of RECS-3D MERgE was significantly lower than that of 3D MERgE while the wall-lumen CTR of RECS-3D MERgE was significantly higher. There were no significant differences in plaque burden measurements between RECS-3D MERgE and 2D DIR-FSE. For comparison between conventional 3D MERgE and 2D DIR-FSE, there were no significant differences in LA measurement. However, the wa of 3D MERgE was significantly larger. The RECS-3D MERgE sequence achieved more sufficient blood suppression and higher image contrast without prolonging the scan time. These improvements lead to more accurate morphological measurements of carotid atherosclerotic imaging.

Variations of optic properties of water under action of static magnetic field

引用

Chinese Science Bulletin 2007年第23期52卷 3179-3182页

作者： DENg bo PANg XiaoFeng School of Life Science and Technology University of Electronic Science and Technology of China Chengdu 610054 China

Effects of static magnetic field on optic properties of water are investigated by infrared spectroscopy, ultraviolet spectroscopy and X-ray diffraction, respectively. The ultraviolet spectroscopy experiments show the changes of properties of water under action of static magnetic field, in the region of 191 to 400 nm. The infrared experiment shows that the water exposed in a magnetic field had saturation and memory effects. The magnetized effects increased with increasing exposed time, but were weakened with increasing of time when the magnetic field was removed. In the X-ray experiment, the strength of diffraction increased also, after the water was exposed in magnetic field. Meanwhile, the shift of peak and increase of strength of X-ray diffraction of magnetized water added with nanoFe3O4 occurred as compared with that of pure water added with nano Fe3O4. This result suggests that the magnetized wa- ter has certain magnetism. Finally, these phenomena are simply explained by the molecular structure of water and the theory of magnetization of water.

巫山县地处三峡库区的腹心地带,三峡水库蓄水后,人地矛盾将更加尖锐。以巫山县为研究对象,运用生态足迹模型对巫山县2006年生态足迹进行定量计算和分析,结果表明:2006年巫山县的人均生态足迹为1.296 9 hm2,可利用的人均生态承载力仅为0.559 2 hm2,人均生态赤字高达0.737 7 hm2。其中,生态赤字部分主要来源于耕地产品、草地类产品和能源的消费。可见,巫山县的人类社会活动对自然资源的消耗已经超过了巫山县生态系统的承受能力,区域发展处于不可持续状态。并在结果分析的基础上提出了实现巫山县可持续发展的措施。
