Invasion of Colorado potato beetle,Leptinotarsa decemlineata,in China: dispersal,occurrence, and economic impact

Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), is a global destructive pest of potato, Solanum tuberosum L. (Solanaceae). It is also an important quarantine pest in China, but its dispersal history, occurrence, and economic impact in China have not yet been reported. We determined the current distribution of CPB and reconstructed its dispersal routes. We also investigated the density of CPB in China in 2006, 2007, 2009, and 2010, and estimated the economic impact of CPB in China. In 1993, CPB was first detected in Xinjiang and subsequently spread eastward. The CPB entered China at three distinct points in Xinjiang: in Huocheng County, Tacheng City, and Habahe County. As of 2010, CPB had invaded 38 counties and cities in China, with a distribution area of 277 000 km², between 42°40′–48°28′N and 80°15′–90°41′E. The distribution area could be divided into four zones (from south to north): Ili River Valley, northern slope of the Tianshan Mountains, Tacheng Basin, and Altay. The average annual dispersal rates in the four zones were 18, 45, 12, and 24 km year^?1, respectively. In China, CPB seriously damages potato, impacts eggplant, Solanum melongena L., and occasionally harms tomato, Solanum lycopersicum L. The current annual economic loss caused by CPB in China is estimated to be 3.2 million USD. The potential annual economic losses after completion of its invasion in China is estimated to be 235 million USD. Future invasion pathways, factors affecting CPB dispersal, and control measures were discussed.

Lower Middle Devonian,Eifelian, crinoids from central Guangxi,South China

The extensive Devonian marine deposits of South China have yielded few articulated crinoid cups or theca. Two Eifelian specimens, from the Gupa Member, are the first ones reported from the Yingtang Formation, Eifelian, from the Ma’anshan section, Guangxi, South China. The new taxon Guangxicrinus xiangzhouensis n. gen. n. sp. is the first report of a marsupiocrinid in China, extending the paleogeographic range of the family into the Paleotethys and the stratigraphic range of the family upward from the upper Silurian into the lower Middle Devonian, Eifelian. The occurrence of Halocrinites sp. is the third occurrence of a cupressocrinitid in China and extends the paleogeographic range from Yunnan to Guangxi.

Characterization of an outbreak of hand, foot, and mouth disease in Nanchang, China in 2010

Recent outbreaks of human enterovirus 71 (EV71) infection and EV71-associated hand, foot, and mouth disease (HFMD) in China have affected millions and potentially lead to life-threatening complications in newborns. Furthermore, these outbreaks represent a significant global public health issue in the world. Understanding the epidemiology of HFMD and EV71 infection and their transmission patterns in China is essential for controlling outbreaks. However, no studies on the outbreaks of HFMD and EV71 infection in China during 2010 have been reported. In this report, we carried out an epidemiological analysis to study an outbreak of HFMD and EV71 infection in 2010 in the city of Nanchang in the Jiangxi province of People's Republic of China. From April 7 to May 11, 2010, a total of 109 HFMD cases were reported, and in this report the HFMD cases were studied by both epidemiological and laboratory analyses. The epidemiological study indicates that children aged younger than 8 years old represented more than 90% of the reported cases, with the age group of 1-3 years containing the highest number of cases. Laboratory studies detected a high prevalence of EV71 amongst the cases in our study, suggesting EV71 as a common enterovirus found in HFMD cases in Nanchang. Phylogenetic analysis of the sequence of the VP1 region of four EV71 isolates indicated that the Nanchang strains belong to the C4 subgenotype commonly found in China during outbreaks in 2008 but contain distinct variations from these strains. Our study for the first time characterizes the epidemiology of HFMD and EV71 infection in China in 2010 and furthermore, provides the first direct evidence of the genotype of EV71 circulating in Nanchang, China. Our study should facilitate the development of public health measures for the control and prevention of HFMD and EV71 infection in at-risk individuals in China.

Health Risk Assessments Based on Existing Data of Arsenic,Chromium, Lead,and Zinc in China's Air

Health risk assessments of As, Cr, Pb, and Zn in air in China were carried out from a national perspective. Concentrations of the four metals in air were gathered from published literature. Health risk assessment models recommended by the U.S. Environmental Protection Agency (USEPA) were applied to quantitatively characterize risk values of the metals by considering different age groups. Results showed that the atmospheric metal concentrations in most regions of China were lower than their inhalation reference concentrations provided by the USEPA, or limited values provided by China. Non-carcinogenic hazard values of the four metals in different regions of China were all lower than 1, indicating no or low non-carcinogenic hazard. However, the probabilities of carcinogenic risk values for As and Cr exceeding the acceptable value (1.0E-05) were 9% and 10% on a national scale, respectively. Some regions, such as Shanxi, Chongqing, Liaoning, and Shanghai, should be studied in more detail. Despite uncertainties, the results of this study provide information on the health risk of As, Cr, Pb, and Zn in air in China.     

中国大陆特有华溪蟹属分布格局探讨(甲壳纲,十足目,溪蟹科)

华溪蟹属Sinopotamon是中国淡水蟹类的特有属。在构建种群数据库的基础上,对华溪蟹属的分布格局进行了深入的研究。结果显示:迄今,华溪蟹属已报告75种和9亚种,占中国淡水蟹总数的29.68%(84/283),系中国淡水蟹36个属中所含种及亚种最多的一个类群,广泛分布于赣、鲁、苏、皖、浙、闽、湘、鄂、粤、桂、川、黔、豫、晋、陕、陇、冀计17个省区。华溪蟹属的分布格局与中国自然地理环境区域分异密切相关,自然地理的阻限等因素是导致华溪蟹属在中国高度分化的主要原因,表现出该属下物种对现代自然条件的适应及其遗传与分化至现阶段的结果。依照中国淡水蟹类地理区划的划分,华溪蟹属分属于西南区、华中区、华南区、华北区及其各亚区的东部季风区内,以东洋界物种成分为绝对优势,其地理分布约以24°N为其南限,37°N为北限,经度则为103°E以东直至东南沿海地区。在垂直分布上,该属物种多分布在海拔200～1000m。又以长江中下游一带物种最为丰富,而黄河与淮河流域则相对贫乏。秦岭及其淮河一线成为华溪蟹属东洋界和古北界物种的明显分野地域,但二界之间存在广泛过渡与渗透。据此,华溪蟹属的地理分布,均受制于中国第2级阶梯和第3级阶梯内的秦岭、雪峰山、巫山、太行山、南岭、武夷山等主要山脉及其低岗丘陵与平原地域。     

Invasion biology,ecology, and management of Frankliniella occidentalis in China

Frankliniella occidentalis is an economically important invasive pest worldwide, which can damage various horticultural crops and ornamental plants. F. occidentalis was first intercepted in Kunming, Yunnan province in 2000, and first reported to establish a population in Beijing, China in 2003. Since then, this pest is currently distributed across tens of provinces in mainland China and cause increasingly serious damage and loss. To control this pest, invasion biology, monitoring, and integrated pest management have been generally and intensively studied for 15 years in China. Furthermore, western flower thrips (WFT) as an important invasive insect pest, the research achievements on WFT has contributed to the promotion of technological innovation and development for invasive alien species management strategies and techniques in China. This review provides an overview for research on the biology, ecology, prevention, and management of this pest during 15 years in China. Meanwhile, China's “4E action” strategy on F. occidentalis is also discussed in this review.

Maritime Legislation of Mainland China and Taiwan: Developments,Comparison, Implications,and Potential Challenges for the United States

In January 1998, Taiwan promulgated the Law of the Republic of China (ROC) on the Territorial Sea and the Contiguous Zone and the Law of the Republic of China on the Exclusive Economic Zone (EEZ) and the Continental Shelf, both of which came into force on January 21, 1998. On June 26, 1998, China adopted the Law of the People's Republic of China on the Exclusive Economic Zone and the Continental Shelf, which is the most significant maritime legislation since its 1992 Law on the Territorial Sea and the Contiguous Zone. This article studies the recent maritime legislation developments in Mainland China and Taiwan, the differences and similarities between the two sets of laws, their implications for the Asia-Pacific region, and the potential challenges for the United States.
