1Influence of Garlic Intercropping or Active Emitted Volatiles in Releasers on Aphid and Related Beneficial in Wheat Fields in China显示文摘In order to develop biological control of aphids by a 'push-pull'approach, intercropping using repellent emitting plants was developed in different crop and associated plant models. Garlic is one of the potential plant that could be inserted in crops to decrease the pest occurrence in neighboring crop plots. In this study, field works were conducted in wheat fields in Langfang Experimental Station, Hebei Province in China from October 2009 to July 2010 during wheat developmental season. The effect of wheat intercropping with garlic but also the volatiles emission on the incidence of the English grain aphid, Sitobion avenae Fabricius (Homoptera: Aphididae) was assessed. Natural beneficial occurrence and global yields in two winter wheat varieties that were susceptible or resistant to cereal aphid were also determined comparing to control plots without the use of garlic plant intercrop nor semiochemical releaser in the fields. S. avenae was found to be lower in garlic oil blend treatment (GOB), diallyl disulfide treatment (DD) and wheat-garlic intercropping treatment (WGI) when compared to the control plots for both two varieties (P<0.01). Both intercropping and application of volatile chemicals emitted by garlic could improve the population densities of natural enemies of cereal aphid, including ladybeetles and mummified aphids. Ladybeetle population density in WGI, GOB and mummified aphids densities in WGI, DD were significantly higher than those in control fields for both two varieties (P<0.05). There were significant interactions between cultivars and treatments to the population densities of S. avenae. The 1 000-grain weight and yield of wheat were also increased compared to the control. Due to their potential alternatives as a biological control agent against cereal aphid, garlic intercropping and related emitted volatiles are expected to contribute to the further improvement of integrated pest management systems and to potentially reduce the amount of traditional synthetic pesticides applied in wheat fields.ZHOU Hai-bo CHEN Ju-lian LIU Yong Frédéric Francis Eric Haubruge Claude Bragard SUN Jing-rui CHENG Deng-fa 2013Journal of Integrative Agriculture2013,12,3:12
2小麦挥发物对蚜虫及其天敌的行为影响——田间有效挥发性信息化合物的筛选(英文)显示文摘【目的】植物挥发性信息化合物能够影响植食性昆虫及其他天敌行为,因此,在植物-植食性昆虫-天敌互作系统中具有重要地位。目前,小麦[Triticum aestivum L.(Gramineae)]中多种挥发物已被鉴定,为明确其对蚜虫及其天敌的行为影响。【方法】本试验利用四臂嗅觉仪和风洞测定4种不同浓度的小麦挥发物(水杨酸甲酯、3-己酰醋酸酯、己烯醇和1-己醇)对麦长管蚜Sitobion avenae(Fabricus)及其两种重要天敌,异色瓢虫[Harmonia axyridis(Pallas)(Coleoptera:Coccinellidae)]和黑带食蚜蝇[(Episyrphus balteatus(De Geer)(Diptera:Syrphidae)]的行为反应。【结果】结果显示,水杨酸甲酯仅吸引异色瓢虫。3-己酰醋酸酯和己烯醇吸引麦长管蚜及异色瓢虫,但随其浓度增加对蚜虫的吸引作用降低,对异色瓢虫吸引作用增强。3-己酰醋酸酯对黑带食蚜蝇也具有吸引作用。另外,与天敌相比,1-己醇对麦长管蚜吸引作用更强。【结论】总之,本试验明确除1-己醇外,水杨酸甲酯、3-己酰醋酸酯、己烯醇可以作为吸引天敌,控制蚜虫的潜在用于推-拉策略的挥发物性化学信息物。解海翠 Durieux Delphine 范佳 刘勇 Bragard Claude Haubruge Eric 孙京瑞 Francis Frédéric 陈巨莲 2014应用昆虫学报2014,51,6:8
3Genetic Variation Among the Geographic Population of the Grain Aphid, Sitobion avenae (Hemiptera: Aphididae) in China Inferred from Mitochondrial COI Gene Sequence显示文摘In order to characterize the genetic relationship of the geographic populations of Sitobion avenae (Hemiptera: Aphididae) in China, a 588 bp region of the mitochondrial cytochrome oxidase subunit I (mtDNA-COI) gene was sequenced and analyzed among the different geographic populations. 269 individuals were collected from 17 localities in different wheat-growing areas in China that covered most of the range reported for this species. Within the sequence among these geographic populations, 15 polymorphic sites defined 16 distinct haplotypes, ranging in sequence divergence from 0.2% (one nucleotide) to 1.7% (10 nucleotides). Of the 15 variable sites, 12 were transitional substitutions, 2 were transversional substitutions and 1 was transitional and transversional substitution. Phylogenetic analysis showed that all haplotypes were highly interconnected with each other, in absence of phylogeographic structing. Each of 8 haplotypes was found only at one locality, and the other haplotypes were the widespread distributed in the different localities. The higher genetic diversity was found in the northern China populations than that in the southern China populations. The low genetic differentiation (FST=-0.06945-0.69857) and high migration rate (Nm=0.21575-infinite) of Chinese populations suggest that dispersal over long distance is a major factor in the demography of S. avenae.XU Zhao-huan CHEN Ju-lian CHENG Deng-fa LIU Yong Frédéric Francis 2011Agricultural Sciences in China2011,10,7:7
4手性农药丁氟螨酯对斑马鱼胚胎的选择性发育毒性显示文摘近年来丁氟螨酯(CYF)对非靶标生物的发育毒性已成为一个值得关注的问题,但其对水生生物的对映选择性效应尚不清晰.为评估丁氟螨酯对斑马鱼胚胎的对映选择性毒性,通过96 h的暴露试验,研究了梯度浓度的丁氟螨酯消旋体及对映体对斑马鱼胚胎的急性毒性.此外,试验还研究了丁氟螨酯对斑马鱼胚胎孵化率、卵黄囊水肿、心包囊水肿和身体弯曲的影响.根据急性毒性结果可知,毒性大小为S⁃CYF>Rac⁃CYF>R⁃CYF,其中S⁃CYF的毒性是R⁃CYF的2.3倍.72 hpf,500 mg·L^(-1)的S⁃CYF可显著诱导胚胎产生卵黄囊水肿(YSE)、体轴弯曲(CB)等畸形效应(p<0.05),而Rac⁃CYF降低了斑马鱼胚胎的孵化成功率.在本研究中发育毒性效应结果与急性毒性结果一致,均为S⁃CYF>Rac⁃CYF>R⁃CYF,表明丁氟螨酯对斑马鱼胚胎存在显著的对映选择性发育毒性,研究结果为丁氟螨酯的环境风险评估提供了理论依据.高腾飞 李敏敏 孔志强 王瑞 全蕊 张嘉 李瑞瑆 叶丰 Frédéric Francis 王凤忠 范蓓 2021环境科学学报2021,41,2:5
5Silvicultural alternatives to conventional even-aged forest man-agement-what limits global adoption?显示文摘Background: The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive management operations focused on increased commodity production, mostly wood. This 'conventional' forest management approach has typically favored production of even-aged, single-species stands. While alternative management regimes have generally received less attention, this has been changing over the last three decades, especially in countries with developed economies. Reasons for this change include a combination of new information and concerns about the ecological consequences of intensive forestry practices and a willingness on the part of many forest owners and society to embrace a wider set of management objectives. Alternative silvicultural approaches are characterized by a set of fundamental principles, including avoidance of clearcutting, an emphasis on structural diversity and small-scale variability, deployment of mixed species with natural regeneration,and avoidance of intensive site-preparation methods.Methods: Our compilation of the authors' experiences and perspectives from various parts of the world aims to initiate a larger discussion concerning the constraints to and the potential of adopting alternative silvicultural practices.Results: The results suggest that a wider adoption of alternative silvicultural practices is currently hindered by a suite of ecological, economic, logistical, informational, cultural, and historical constraints. Individual contexts display their own unique combinations and relative significance of these constraints, and accordingly, targeted efforts, such as regulations and incentives, may help to overcome specific challenges.Conclusions: In a broader context, we propose that less emphases on strict applications of principles and on stand structures might provide additional flexibility and facilitate the adoption of alternative silvicultural regimes in a broader set of circumstances. At the same time, the acceptance of alternative silvicultural systems as the 'preferred or default mode of management' wil necessitate and benefit from the continued development of the scientific basis and valuation of a variety of ecosystem goods and services. This publication is aimed to further the discussion in this context.Klaus J Puettmann Scott McG Wilson Susan C Baker Pablo J Donoso Lars Dr?ssler Girma Amente Brian D Harvey Thomas Knoke Yuanchang Lu Susanna Nocentini Francis E Putz Toshiya Yoshida Jürgen Bauhus 2015Forest Ecosystems2015,2,2:4
