| 1 | Invasive mechanism and control strategy of Ageratina adenophora (Sprengel)显示文摘In order to ascertain the invasive mechanism and control strategy of the invasive Crofton weed, Ageratina adenophora, its ecological adaptability and population differentiation,the formation of single dominant population, displacement of native plants and sustainable management strategies were investigated. The present results helped to clarify and explain such issues as the adaptability post invasion,interaction and competition between inter-and intra-species and community resistance, thereby providing important references to researches on other invasive alien species. | WAN FangHao1, LIU WanXue1, GUO JianYing1, QIANG Sheng2, LI BaoPing2, WANG JinJun3, YANG GuoQing1, NIU HongBang1, GUI FuRong1, HUANG WenKun1, JIANG ZhiLin1 & WANG WenQi3 1State Key Laboratory for Biology of Plant Diseases and Insect Pests, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, Beijing 100193, China 2College of Plant Protection, Nanjing Agricultural University, Nanjing 210095, China 3Key Laboratory of Entomology and Pest Control Engineering, College of Plant Protection, Southwest University, Chongqing 400716, China | 2010 | Science China(Life Sciences)2010，53，11： | 42 |
| 2 | Invasive mechanism and management strategy of Bemisia tabaci(Gennadius) biotype B:Progress report of 973 Program on invasive alien species in China显示文摘Bemisia tabaci(Gennadius) biotype B,called a 'superbug',is one of the most harmful biotypes of this species complex worldwide.In this report,the invasive mechanism and management of B.tabaci biotype B,based on our 5-year studies,are presented.Six B.tabaci biotypes,B,Q,ZHJ1,ZHJ2,ZHJ3 and FJ1,have been identified in China.Biotype B dominates the other biotypes in many regions of the country.Genetic diversity in biotype B might be induced by host plant,geographical conditions,and/or insecticidal application.The activities of CarE(carboxylesterase) and GSTs(glutathione-S-transferase) in biotype B reared on cucumber and squash were greater than on other host plants,which might have increased its resistance to insecticides.The higher activities of detoxification enzymes in biotype B might be induced by the secondary metabolites in host plants.Higher adaptive ability of biotype B adults to adverse conditions might be linked to the expression of heat shock protein genes.The indigenous B.tabaci biotypes were displaced by the biotype B within 225 d.The asymmetric mating interactions and mutualism between biotype B and begomoviruses via its host plants speed up widespread invasion and displacement of other biotypes.B.tabaci biotype B displaced Trialeurodes vaporariorum(Westwood) after 4-7 generations under glasshouse conditions.Greater adaptive ability of the biotype B to adverse conditions and its rapid population increase might be the reasons of its successful displacement of T.vaporariorum.Greater ability of the biotype B to switch to different host plants may enrich its host plants,which might enable it to better compete with T.vaporariorum.Native predatory natural enemies possess greater ability to suppress B.tabaci under field conditions.The kairomones in the 3rd and 4th instars of biotype B may provide an important stimulus in host searching and location by its parasitoids.The present results provide useful information in explaining the mechanisms of genetic diversity,evolution and molecular eco-adaptation of biotype B.Furthermore,it provides a base for sustainable management of B.tabaci using biological and ecological measures. | WAN FangHao1,ZHANG GuiFen1,LIU ShuSheng2,LUO Chen3,CHU Dong4,ZHANG YouJun4,ZANG LianSheng2,JIU Min2,Lü ZhiChuang1,CUI XuHong1,ZHANG LiPing4,ZHANG Fan3,ZHANG QingWen5,LIU WanXue1,LIANG Pei5,LEI ZhongRen1 & ZHANG YongJun1 1 State Key Laboratory for Biology of Plant Diseases and Insect Pests,Institute of Plant Protection,Chinese Acadeny of Agriculture Sciences,Beijing 100094,China 2 Institute of Applied Entomology,Zhejiang University,Hangzhou 310029,China 3 Institute of Plant and Environment Protection,Beijing Academy of Agricultural and Forestry Sciences,Beijing 100089,China 4 Institute of Vegetables and Flowers,Chinese Acadeny of Agricullare Sciences,Beijing 100081,China 5 Department of Entomology,China Agriculture University,Beijing 100094,China | 2009 | Science China(Life Sciences)2009，52，1： | 30 |
| 3 | Identification of Chinese populations of Bemisia tabaci (Gennadius) by analyzing ribosomal ITS1 sequence显示文摘Spreading of Bemisia tabaci B biotype has had a large impact on the production of vegetables, ornamental and fiber crops in many countries of the world since the 1990s. This study analyzes the ribosomal ITS1 sequence (~520 bp) to distinguish genetic difference of B. tabaci from representative different geographical populations in China. Phylogenetic analysis shows that populations of B.tabaci from Beijing and Shandong Province are of biotype B, and populations of B.tabaci from sweet potato in Fujian Province and pumpkin in Guangxi, China, belong to two different non-B biotypes and have a geographical origin of Asia. | WU Xingxia, LI Zhengxi, HU Dunxiao and SHEN Zuorui(Department of Entomology, China Agricultural University, Beijing 100094, China) | 2003 | Progress in Natural Science:Materials International2003，13，4： | 21 |
| 4 | Changes in biodiversity and ecosystem function during the restoration of a tropical forest in south china显示文摘Tropical forests continue to vanish rapidly,but few long-term studies have ever examined if and how the lost forests can be restored.Based on a 45-year restoration study in south China,we found that a tropical rain forest,once completely destroyed,could not recover naturally without deliberate restoration efforts.We identified two kinds of thresholds that must be overcome with human ameliorative measures before the ecosystem was able to recover.The first threshold was imposed primarily by extreme physical conditions such as exceedingly high surface temperature and impoverished soil,while the second was characterized by a critical level of biodiversity and a landscape context that accommodates dispersal and colonization processes.Our three treatment catchments(un-restored barren land,single-species plantation,and mixed-forest stand)exhibited dramatically different changes in biodiversity and ecosystem functioning over 4 decades.The mixed forest,having the highest level of biodiversity and ecosystem functioning,possesses several major properties of tropical rain forest.These findings may have important implications for the restoration of many severely degraded or lost tropical forest ecosystems. | REN Hai,LI ZhiAn,SHEN WeiJun,YU ZuoYue,PENG ShaoLin,LIAO ChongHui,DING MingMao & WU JianGuo 1 South China Botanical Garden,Chinese Academy of Sciences,Guangzhou 510650,China 2 Institute of Ecology and Evolution,Zhongshan University,Guangzhou 510275,China 3 Guangdong Institute of Entomology,Guangzhou 510275,China 4 School of Life Sciences and Global Institute of Sustainability,Arizona State University,Tempe,AZ 85287,USA | 2007 | Science China(Life Sciences)2007，50，2： | 9 |
| 5 | Identification and expression profiling of putative odorant-binding proteins in the malaria mosquitoes, Anopheles gambiae and A. arabiensis显示文摘Olfaction plays a major role in host-seeking behaviour of mosquitoes. An informat- ics-based genome-wide analysis of odorant-binding protein (OBP) homologues is under- taken, and 32 putative OBP genes in total in the whole genome sequences of Anopheles gam- biae are identified. Tissue-specific expression patterns of all A. gambiae OBP candidates are determined by semi-quantitative Reverse Transcription (RT)-PCR using mosquito actin gene a internal expression control standard. The results showed that 20 OBP candidates had strong expression in mosquito olfactory tissues (female antennae), which indicate that OBPs may play an important role in regulating mosquito olfactory behaviours. Species-specific expression pat- terns of all putative anopheline OBPs are also studied in two of the most important malaria vec- tors in A. gambiae complex, i.e. A. gambiae and A. arabiensis, which found 12 of the putative OBP genes examined displayed species-differential expression patterns. The cumulative relative expression intensity of the OBPs in A. arabiensis antennae was higher than that in A. gambiae (the ratio is 1441.45:1314.12), which might be due to their different host preference behaviour. While A. gambiae is a highly anthropophilic mosquito, A. arabiensis is more opportunistic (Vary- ing from anthropophilic to zoophilic). So the latter should need more OBPs to support its host selection preference. Identification of mosquito OBPs and verification of their tissue- and spe- cies-specific expression patterns represent the first step towards further molecular analysis of mosquito olfactory mechanism, such as recombinant expression and ligand identification. | LI Zhengxi1,Jing-Jiang ZHOU2,SHEN Zuorui1 & Lin FIELD2 1.Department of Entomology,China Agricultural Univeristy,Beijing 100094,China 2.Biological Chemistry Division, Rothamsted Research,Harpenden, Herts.

| 6 | Molecular characterization and developmental expression of the gene encoding the prothoracicotropic hormone in the beet armyworm, Spodoptera exigua显示文摘Prothoracicotropic hormone (PTTH), a neuropeptide hormone stimulating the prothoracic glands to synthesize ecdysone, plays an important role in regulating postembryonic development in insects. The cDNA encoding PTTH was isolated and sequenced from the beet armyworm, Spodoptera exigua (Spe). The deduced a?mino acid sequence is composed of a signal peptide, a peptide (65 amino acids) of un-known function, and a mature PTTH molecule (111 amino acids). The Spe-PTTH shows similarities (45.5%―70.3%) to other known PTTHs reported in Lepidoptera species, but 7 cysteine r?esidues and the hydrophobic regions were conserved. Whole-mount immunocytochemistry by using an antiserum against recombinant Helicoverpa armigera PTTH showed that Spe-PTTH was synthesized in two pairs of neurosecretory cells in the S. exigua brain. Northern blot analysis demonstrates the presence of a 1.2-kb transcript in the brain. The Spe-PTTH mRNA is detectable at high levels at the wandering larval stage, early pupal stage, and pharate adult stage, suggesting that the Spe-PTTH gene might be corre-lated with molting, metamorphosis, and reproduction. | XU Jun1,SU JianYa3, SHEN JinLiang3 & XU WeiHua1,2 1 Department of Molecular and Cell Biology, School of Life Sciences, University of Science and Technology of China, Hefei 230027, China 2 State Key Laboratory of Biocontrol and Institute of Entomology, School of Life Sciences, Zhongshan University, Guangzhou 510275, China 3 Department of Plant Protection, Nanjing Agriculture University, Nanjing 210095, China | 2007 | Science China(Life Sciences)2007，50，4： | 3 |
| 7 | 思茅松毛虫的研究显示文摘思茅松毛虫是中国南部的重要松毛虫之一。以Pinus langbianensis Chu为食和以Keteleeria evelyniana为食的幼虫在形态上及发育上均有重大差异。 在安宁,幼虫主要取食Keteleeria evelyniana,每年发生1—2代。越冬后的幼虫在5—6月间化蛹而后在6—7月间发育成熟羽化。第一代幼虫在生长发育过程中产生分化:大部分幼虫生长缓慢而以幼虫越冬,其余的幼虫在四龄后生长迅速,于8月底化蛹、羽化,第二代幼虫于9月中、下旬孵化而以三龄幼虫越冬。引起分化的原因还不明了,应予深入研究。我们设想至少应追索到第一代幼虫孵化之前,因为在7月以前孵化的同一母虫的幼虫都可以产生分化。 这一害虫的化学防治试验了13种杀虫剂,每公斤“621烟剂加5%DDVP40毫升的试验在野外进行,死亡率高达90%。其他:50%phoxim 1:15000,90%Trichlorphon 1:15000,50%嘧啶硫磷1:3000,50%Cyanophos 1:5000,30%phosvel1:5000,40%伏地松1:5000,20%MTMC1:500,25%Carbaryl1:250,95%Cartap1:5000,50%Chorophenmidine1:1000,50%Garodona1:600及50%12401:3000倍均在室内进行试验,死亡率高达90%—100%。 | Teaching and Research Group of Forest Entomology | 1981 | 北京林业学院学报1981，，1： | 2 |
| 8 | Ecdysteroids in the adults and eggs of Opogona sacchari (Bojer),an invasive alien pest显示文摘In order to understand the composition and quantitative variation of ecdysteriods in the adults and eggs of Opogona sacchari (Bojer), an invasive alien pest, we analyzed the ecdysteroid composition and titers in the adult and egg of this pest. On day 4 after eclosion, the titer of ecdysteriods in the male adult was 0.080 ng/adult, much lower than 5.978 ng/adult in the female adult. During the development of ovaries, the titer of ecdysteriods was low on the first two days, and high in the late period, with the peak (10.48 ng/ovary) appearing on day 3. During the development of eggs, the titer of ecdysteriods was about 0.010 ng/egg from day 1 to day 3, and then decreased to 0.006 ng/egg on day 4. In both adults and eggs, three main components of ecdysteriods were found by identification of HPLC/RIA. They were 20-hydroxyecdysone, 26-hydroxyecdysone, and an unidentified component. | WANG FangHai, ZHANG GuRen, WEN RuiZhen & HE GuoFeng State Key Laboratory for Biological Control and Institute of Entomology, Sun Yat-sen University, Guangzhou 510275, China | 2008 | Science China(Life Sciences)2008，51，2： | 1 |
| 9 | FURTHER DESCRIPTION OF Strobilomyia melaniola(Fan)(Diptera:Anthomyiidae)显示文摘In a recent paper,V.Michelsen(1988,Systematic Entomology 13:271--314)revised18 world species of anthomyiid cone and seed pests and described a new genus,Strobilomyia gen.n.He considered S.melaniola of Noutheast China to be a synonym of S.viaria of North America.That they are the same species is not accepted.We compared the morphological characters of maleand female S.melaniloa adults with the close relatives,S.viaria and S.sibirica.We conclude thatthey are not the same species and that S.melaniola is an independent species. | Fan Zidc Chen ZhiziShanghai Institute of Entomology, Acadcmia Sinica P.

| 10 | Observation on the initial inoculum source and dissemination of Entomophthorales-caused epizootics in populations of cereal aphids显示文摘A total number of 1092 migratory alates were trapped from air in wheat grown area of Yuanyang County, Henan Province from early April through May 2002 in order to confirm the source and dissemination of entomophthoralean inocula to cause epizootics of cereal aphids. Those included 415 Sitobion avenae, 642 Rhopalosiphum padi, 22 Metopolophium dirhodum, and 13 Schizaphis graminum. The trapped alates were daily collected and individually reared for 7 days on wheat plants in laboratory. Of those 341 alates died of fungal infection, taking 31.2% in the trapped alates. These included 224 S. avenae, 106 R. padi, 8 M. dirhodum, and 3 S. graminum. Deaths of all infected alates occurred during the first 5 days and 78.9% of the deaths occurred within the first 3 days. Individual examination under microscope proved that all deaths were attributed to entomophthoralean fungi. Of those Pandora neoaphidis accounted for 84.6%, Conidiobolus obscurus for 9.9%, and Entomophthora planchoniana for 5.5%. Four alate deaths died of cross infection of P. neoaphidis and C. conidiobolus. Based on the high infection rate of the migratory alates trapped from air and the field occurrence of epizootics in populations of cereal aphids during the trapping period, Entomophthorales-caused epizootics were likely disseminated by infected alates through their flight and colonization. This makes it reasonable to interpret worldwide distribution of aphid epizootics, particularly caused by P. neoaphidis that has no resting spores discovered. | CHEN Chun & FENG MingguangInstitute of Microbiology, College of Life Science, Zhejiang University, Hangzhou 310029, China Institute of Applied Entomology, College of Agricultural Sciences and Biotechnology, Zhejiang University, Hangzhou 310029, China | 2004 | Science China(Life Sciences)2004，47，1： | 1 |

| 14 | The Utility of Specific Markers Based on ITS2 Sequences for Molecular Identification and Detection of Trichogramma spp.显示文摘The technology based on specific PCR amplification using internal transcribed spacer 2 of nuclear ribosomal DNA for molecular identification and detection of Trichogramma species was studied. Firstly the ITS2s of six Trichogramma species were cloned and sequenced, and the interspecific sequence variation was analyzed. Secondly the ITS2 regions of six geographical populations of T. dendrolimi were cloned and sequenced, and the intraspecific sequence identity was analyzed. The results show that the interspecific variation and intraspecific similarity of ITS2 sequences are very suitable for designation of specific primers at specieslevel. Screening of specific primers for T. dendrolimi leads to final sensitive and stable diagnostic primers. This system lets non-specialists can not only identify adults (males and females), but also identify eggs in parasitized hosts rapidly and accurately, which is impossible by conventional methods. Further development of this protocol can create a complete set of specific primers for different species of the whole genus Trichogramma. | LI Zheng-xi and SHEN Zuo-rui(Department of Entomology, China Agricultural University, Beijing 100094 , P.R.China) | 2002 | Agricultural Sciences in China2002，1，9： | 1 |

| 19 | Molecular Weight of Cytoplasmic Malate Dehydrogenase,Mitochondrial Malate Dehydrogenase and Lactate Dehydrogenase of a Freshwater Catfish显示文摘The multiple molecular forms of cytoplasmic malate dehydrogenase (cMDH), mitochondrial malate dehydrogenase (mMDH ) and lactate dehydrogenase (LDH ) were studied in the liver and skeletal muscle of the freshwater catfish, Clarias batrachus. There were two electrophoretically distinguishable bands (AA andBB) of cMDH and mMDH which suggests that they are apparently encoded at two gene loci (A and B) in both the tissues.However, the presence of a single band (LDH-1 ) of LDH in liver and double bands (LDH-1and LDH-2) in skeletal muscle in which LDH-2 was predominant reflects the differential expression of LDH genes in different metabolic tissues to meet the requirement of energy production. The AA isoform (74 kd) of liver cMDH was smaller than those of the AA form (110 kd) of skeletal muscle. In contrast, the BB isoform of liver (42 kd) and skeletal muscle (54 kd) were more or less similar in size. Unlike the case of cMDH, the molecular weight of AA isoform (115 kd) of liver mMDH was higher than those of the AA form (87kd) of skeletal muscle. Whereas the molecular weight of BB isoform (58 kd) of liver was in proximity to the weight of BB form (44 kd) of skeletal muscle mMDH. The size of AA isoform (74 kd) of liver cMDH was smaller, while the AA isoform (110 kd) of skeletal muscle was larger as compared to AA form of mMDH in the liver (115 kd) and skeletal muscle (87 kd). But the size of BB isoform of both the isozymes was almost equal in these metabolic tissues. The molecular weight of liver LDH-1 (96 kd) was close to the weight of LDH-1 (82 kd) in skeletal muscle. The molecular weight of skeletal muscle LDH-2 was deduced as 37 kd which is much more lower than the weight of LDH-1 in liver and skeletal muscle. The smaller size of LDH-2 in skeletal muscle may be of a physiological significance in this anaerobic | G.

| 20 | Synthesis and bioassay of all four stereoisomers of (2E,4E)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one, the assignment of the absolute configuration of the sex pheromone of Matsucoccus matsumurae Japanese pine bast scale显示文摘A facile enantioselective synthesis of all four stereoisomers of (2E,4E)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one (1) is described. The stereochemistry at 6-C and 10-C of 1 was constructed by using optically active citronellal as starting material and by the asymmetric crotylic metal reaction. In the bioassay and field tests, only la, i.e. (6R,10R)-1 was active. The other three isomers 1b (6S,10R), 1c (6R,10S) and 1d (6S,10S) were inactive. Therefore, the naturally occurring pheromone was assigned as (6K,10R)-1. | LIN, Guo-Qiang XU, Wei-ChuShanghai Institute of Organic Chemistry, Chinese Academy of Sciences, Shanghai 200032, ChinaQI, Yun-Tai CHEN, Guo-MinShanghai Institute of Entomology, Chinese Academy of Sciences, Shanghai 200025, China | 1995 | Chinese Journal of Chemistry1995，13，1： | 0 |
