The first steps in the development of dicamba tolerant transgenic plants were conducted by Sandoz Crop Protection in Palo Alto, CA and then contractually followed up at the University of Nebraska. The subsequent development by Monsanto of soybean and cotton varieties that would tolerate post-emergent application of dicamba substantially changed the use patterns of dicamba in the United States. Transgenic dicamba-tolerant (DT) seeds were first approved in 2016 in the United States, although the post-emergent use of dicamba was not legal that year. In 2017 and 2018, there was substantial market penetration of DT soybean and cotton seeds into the market and the occurrence of dicamba off-target movement (OTM) was highly variable across the United States. The driving force behind these new seed traits was the widespread failure of glyphosate to control broadleaf weeds effectively, especially those from the Conyza and Amaranthus genera. Herbicide research and development in the United States has historically involved both industry and academic weed scientists usually operating in a symbiotic and mutually respectful relationship, although there may have been disagreements at times about some aspects of herbicides and their development. The relatively recent introduction of DT varieties and legal post-emergent dicamba in the United States was a dynamic time for weed control, and adoption of DT crops and subsequent OTM of dicamba greatly changed the working relationships between academic scientists and representatives from Monsanto and some other private companies. Perhaps the greatest change was the lack of access of research materials that would be available to academic scientists for evaluation prior to the retail sale of those materials. Historically, academic scientists would have the ability to evaluate various new technologies and provide objective, independent comments on their potential utility prior to commercialisation. Monsanto largely restricted access to the DT seeds or new herbicide formulations. There are some states that have long-established policies that they will not recommend a new herbicide technology unless they have examined it under their specific field conditions. For example, University of Arkansas researchers would not recommend the use of post-emergent dicamba on DT crops when it first became legal to use. Monsanto responded by filing legal challenges of various types against the University of Arkansas faculty, including 64 exhibits of various legal aspects. Many other states had varying degrees of restrictions placed upon their research efforts, and most scientists had to sign various forms of confidentiality agreements to obtain access to the research material from Monsanto.

加州帕洛阿尔托的Sandoz Crop Protection进行了开发麦草畏耐受转基因植物的第一步,然后在内布拉斯加大学进行了合同跟进。孟山都公司随后开发出能够耐受麦草畏紧急后施用的大豆和棉花品种,极大地改变了麦草畏在美国的使用模式。转基因麦草畏耐受(DT)种子于2016年在美国首次获得批准,尽管当年麦草畏的紧急使用并不合法。2017年和2018年,DT大豆和棉花种子在市场上的渗透率很高,麦草畏脱靶运动(OTM)在美国各地的发生率变化很大。这些新种子性状背后的驱动力是草甘膦未能有效控制阔叶杂草,尤其是稻属和阿玛兰属的阔叶杂草。美国除草剂的研究和开发历来涉及行业和学术杂草科学家,他们通常以共生和相互尊重的关系运作,尽管有时可能在除草剂及其开发的某些方面存在分歧。最近在美国引入DT品种和合法的后紧急麦草畏是杂草控制的一个动态时期,DT作物的采用和随后麦草畏的OTM极大地改变了学术科学家与孟山都和其他一些私营公司代表之间的工作关系。也许最大的变化是缺乏可供学术科学家在零售这些材料之前进行评估的研究材料。从历史上看,学术科学家有能力评估各种新技术,并在商业化之前对其潜在效用提供客观、独立的评论。孟山都在很大程度上限制了DT种子或新除草剂配方的使用。有些州长期以来一直制定政策,除非在特定的田间条件下进行了检查,否则他们不会推荐新的除草剂技术。例如,阿肯色大学的研究人员在首次合法使用麦草畏时,不会建议在DT作物上使用紧急后麦草畏。作为回应,孟山都对阿肯色大学的教职员工提出了各种类型的法律挑战,包括64份不同法律方面的证据。许多其他州对他们的研究工作有不同程度的限制,大多数科学家必须签署各种形式的保密协议才能从孟山都公司获得研究材料。麦草畏标签在2017年首次推出时和两年后再次推出时存在两大差异。第一个主要区别是标签上明确说明了除草剂耐药性确认、验证和管理的整个章节。这篇论文的作者提醒读者,我们之所以使用麦草畏,是因为草甘膦抗性管理系统的大规模失败。杂草控制的黄金时代,基本上是100%的杂草控制,没有作物伤害,由于完全缺乏任何抗性管理策略而失去了。美国环保局增加了标签语言,希望能避免杂草耐药性的演变再次发生在任何新的除草剂上。许多除草剂使用者期望所有的新标签都包含抗性管理语言。标签的第二个明显变化是有效期,在以前的农药注册中,有效期通常为多年。第一个麦草畏标签于2017年问世,有效期仅为两年。下一个标签于2019年推出,有效期仅为五年,尽管人们对该标签的未来有着广泛的猜测。

The Potential of Fluorescence Imaging to Distinguish Insect Pest and Non-pest Species 荧光成像在区分害虫和非害虫物种中的潜力

Studying the presence and movement of insects is important in biological research for practical purposes regarding control of pests and environmental monitoring. Detection of insects by conventional trapping (e.g. the Rothamsted Insect Survey) and tracking technologies (e.g. the Rothamsted Radar Entomology Unit) have been effective for monitoring and forecasting pest migration but often require significant investment in capital costs and/or staff time. Insect detection using imaging of natural fluorescence (without additional fluorescent dyes) has been considered less, and much of the work on natural fluorescence in the animal world has been on marine organisms. Work on terrestrial arthropods has been more limited and restricted primarily to non-insect arthropods. Very early work on the distribution of fluorescent pigments in butterflies was demonstrated using long wave mercury vapour lamps followed by more work in the 1950s on butterflies, arthropods; including beetles, spiders and millipedes, cockroaches and eggs of Orthoptera. These studies often involved qualitative approaches; dissecting the animals and investigating internal organs and fluids for fluorescence as well as whole body studies. More recent studies have included quantitative work on butterflies and pest insects plus fluorescence studies in damselflies, moths, millipedes, bees and spiders. Fluorescence in juvenile stages is a property used for detection of flies and beetles in food stuffs. The vast majority of insects, however, have not been investigated for fluorescence and even in those taxa that have been studied, e.g. butterflies, the dataset is incomplete. The easiest way to observe fluorescence is to illuminate a subject with a known waveband of light in otherwise darkness and view or record an image via a filter that blocks the wavelength of the illuminating light. Any light viewed or captured at a different wavelength to the illumination, must have been produced by fluorescence. In contrast, some living organisms themselves can produce light or luminescence by internal chemical means. This work aimed to look at the potential of using natural fluorescence to detect and identify insects, particularly pests.
研究昆虫的存在和运动在生物研究中对于害虫控制和环境监测的实际目的非常重要。通过传统诱捕(如洛桑昆虫调查)和跟踪技术(如洛桑雷达昆虫学单位)检测昆虫对监测和预测害虫迁移是有效的,但往往需要大量的资本成本和/或工作人员时间投资。利用天然荧光成像(没有额外的荧光染料)来检测昆虫的研究较少,而动物世界中关于天然荧光的大部分工作都是在海洋生物上进行的。对陆生节肢动物的研究比较有限,主要局限于非昆虫节肢动物。关于蝴蝶体内荧光色素分布的早期研究是用长波汞蒸汽灯进行的随后在20世纪50年代对蝴蝶,节肢动物;包括甲虫、蜘蛛、千足虫、蟑螂和直翅目昆虫的卵。这些研究通常采用定性方法;解剖动物,研究内部器官和液体的荧光以及全身研究。最近的研究包括对蝴蝶和害虫的定量研究,以及对豆娘、飞蛾、千足虫、蜜蜂和蜘蛛的荧光研究。幼年期的荧光是一种用于检测食物中的苍蝇和甲虫的特性。然而,绝大多数昆虫还没有被研究过荧光,甚至在那些被研究过的分类群中,比如蝴蝶,数据集也是不完整的。观察荧光最简单的方法是在黑暗中用已知波段的光照射对象,然后通过阻挡照明光波长的滤光片观察或记录图像。任何以不同波长观察或捕捉到的光都必须是由荧光产生的。相反,一些生物体本身可以通过内部化学手段产生光或发光。这项工作旨在研究利用天然荧光检测和识别昆虫,特别是害虫的潜力。

COP26: What Does It Mean for the Agriculture Sector? COP26:这对农业部门意味着什么?

Climate change challenges and the urgent need to take things seriously were once again thrust into the spotlight in October and November 2021 with the 26th United Nations Climate Change Conference (COP26) held in Glasgow under the presidency of the United Kingdom, in partnership with Italy. COP stands for Conference of the Parties, and the summit was attended by the countries that signed the United Nations Framework Convention on Climate Change (UNFCCC) ? a treaty agreed in 1994. Billed by many as the most significant climate event since the 2015 Paris Agreement, COP26 aimed to accelerate action towards the goals of both the UNFCCC treaty and Paris Agreement, such as for every country to work together to limit global warming to 1.5°C. Nationally Determined Contributions (NDCs) were central to the Paris Agreement and outlined efforts from each country to reduce national emissions and adapt to the impacts of climate change. Unfortunately, the commitments laid out in Paris in 2015 did not come close to achieving the 1.5°C target, and with the window for action becoming ever smaller, there was substantial pressure on Glasgow to deliver something meaningful. Following two weeks of intense negotiations, COP26 finally ended with nearly 200 countries agreeing the Glasgow Climate Pact. Crucially this pact keeps the 1.5°C reduction alive and completes the Paris Rulebook, a set of guidelines for how the Paris Agreement will be delivered including a transparency process to hold countries accountable as they deliver on their targets. But what about agriculture? Despite being the second largest driver of climate change behind the energy sector, and therefore central to meeting emissions reductions and achieving the 1.5°C target, the general consensus was that the agriculture sector did not feature prominently enough at COP26, and that reliance on major pledges and pacts disguised a lack of detail on exactly how action would be achieved. Under the UNFCCC there is only one program focussed on agriculture ? the Koronivia Joint Work on Agriculture (KJWA) which was established at COP23 in 2017 and aims to address agricultural issues through the lens of climate change. It is composed of six interrelated topics, namely soils, nutrient use, water, livestock, methods for assessing adaptation, and the socioeconomic and food security dimensions of climate change across the agricultural sectors. The process was scheduled to finish at COP26; however, by the end of the meeting there were still many areas of disagreement and so these will need to be ironed out in the future. Furthermore, despite pledging action, none of the updated NDCs submitted by the G20 nations prior to COP26 included specific targets on how commitments made for their agricultural sectors would actually be achieved in practice. Many of the current challenges in agriculture are political in nature, whether it is the desire of developed countries to reduce meat and dairy consumption and move towa
2021年10月和11月,英国与意大利合作,在格拉斯哥举行了第26届联合国气候变化大会(COP26),气候变化挑战和认真对待问题的迫切需要再次成为人们关注的焦点。COP代表缔约方大会,签署《联合国气候变化框架公约》(UNFCCC)的国家出席了峰会?1994年达成的一项条约。COP26被许多人称为自2015年《巴黎协定》以来最重要的气候事件,旨在加快实现《联合国气候变化框架公约》条约和《巴黎协定,例如每个国家共同努力将全球变暖限制在1.5°C以内。国家自主贡献是《巴黎协定》的核心,并概述了每个国家为减少国家排放和适应气候变化影响所做的努力。不幸的是,2015年在巴黎做出的承诺并没有接近1.5°C的目标,而且随着行动窗口越来越小,格拉斯哥面临着巨大的压力,需要做出有意义的事情。经过两周的紧张谈判,COP26最终以近200个国家同意《格拉斯哥气候公约》而告终。至关重要的是,这项协议保持了1.5°C的减排,并完善了《巴黎规则手册》,这是一套关于如何实现《巴黎协定》的指导方针,包括一个透明程序,让各国在实现目标时承担责任。但是农业呢?尽管农业是仅次于能源部门的第二大气候变化驱动力,因此也是实现减排和1.5°C目标的核心,但普遍的共识是,农业部门在COP26上的地位不够突出,对主要承诺和协议的依赖掩盖了对如何实现行动缺乏细节。根据《联合国气候变化框架公约》,只有一个项目侧重于农业?Koronivia农业联合工作(KJWA)于2017年在COP23上成立,旨在通过气候变化的视角解决农业问题。它由六个相互关联的主题组成,即土壤、养分利用、水、牲畜、评估适应的方法,以及整个农业部门气候变化的社会经济和粮食安全层面。这一进程计划在第二十六届缔约方大会上结束;然而,到会议结束时,仍有许多领域存在分歧,因此这些问题需要在未来解决。此外,尽管承诺采取行动,但G20国家在COP26之前提交的最新NDC中没有一个包含如何在实践中实际实现其农业部门承诺的具体目标。目前农业中的许多挑战都是政治性的,无论是发达国家希望减少肉类和乳制品消费,转向更多的植物性饮食,还是发展中国家不愿同意,或者讨论农业补贴,因此这些挑战没有得到解决也许并不奇怪。农业作为排放源和汇,在气候变化辩论的双方都发挥着关键作用。包括二氧化碳、甲烷和一氧化二氮在内的全球人为温室气体排放约20%来自农业、林业和土地利用。当考虑到包括作物和牲畜在内的整个农业食品系统时,这一数值将增加到31%。单独划分时,全球农业食品系统的二氧化碳排放量占21%,甲烷排放量占53%,一氧化二氮排放量占78%。虽然大多数部门排放的主要温室气体是二氧化碳,但农业部门的不同寻常之处在于,甲烷和一氧化二氮的直接排放量要高得多。鉴于这些温室气体作为气候变化的关键驱动因素和对农业部门的重要性,审查COP26在这一领域的讨论是及时的。

Contradictory EU policies first encouraged and then undermined the farming of a major biofuel in Europe, according to a new analysis. Climate change polices initially rewarded the widespread planting of oilseed rape – the world's most important vegetable oil after soybean – but subsequent pesticide laws have ultimately led to very large yield losses across the continent in recent years. This collapse of oilseed rape farming in the UK and Europe had led to a reliance on imported oils – including palm oil, the growing of which is often responsible for tropical deforestation, and oilseed rape from countries still using pesticides banned by the EU. The findings of the report were presented at a meeting of the British Crop Protection Council by lead author, Dr Patricia Ortega-Ramos from Rothamsted Research. Speaking ahead of the meeting, she said the series of EU policy decisions essentially 'created a serious crop pest. It is a great example of how a better understanding of pests and joined up decision making are going to be vital if we are to reform farming.

一项新的分析显示,欧盟相互矛盾的政策先是鼓励了欧洲一种主要生物燃料的种植,然后又破坏了这种种植。气候变化政策最初鼓励广泛种植油菜——世界上仅次于大豆的最重要的植物油——但随后的农药法律最终导致近年来整个非洲大陆的产量损失非常大。英国和欧洲油菜种植的崩溃导致了对进口油的依赖——包括棕榈油,棕榈油的种植经常导致热带森林的砍伐,以及来自仍在使用欧盟禁止的杀虫剂的国家的油菜。该报告的主要作者、来自洛桑研究所的Patricia Ortega-Ramos博士在英国作物保护委员会的一次会议上介绍了该报告的发现。她在会议开始前说,欧盟的一系列政策决定实际上“造成了严重的农作物虫害”。这是一个很好的例子,说明如果我们要改革农业,更好地了解害虫和联合决策将是至关重要的。根据这项新的分析,欧盟相互矛盾的政策先是鼓励了欧洲一种主要生物燃料的种植,然后又破坏了这种生物燃料的种植。气候变化政策最初鼓励广泛种植油菜——世界上仅次于大豆的最重要的植物油——但随后的农药法律最终导致近年来整个非洲大陆的产量损失非常大。英国和欧洲油菜种植的崩溃导致了对进口油的依赖——包括棕榈油,棕榈油的种植经常导致热带森林的砍伐,以及来自仍在使用欧盟禁止的杀虫剂的国家的油菜。欧盟2009年的农药可持续使用指令没有得到很好的执行,由于该指令和随后的决定,白菜茎跳蚤甲虫现在已经成为一种严重的害虫。油菜种植面积正在急剧下降,给农民带来了巨大的经济后果,给我们所有人带来了严重的环境后果。

The area of oilseed rape being grown is now falling sharply, with huge financial consequences\u0000 for farmers and major environmental consequences for all of us.","PeriodicalId":19602,"journal":{"name":"Outlooks on Pest Management","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43087579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Management of Date Palm Pests: Lack of Commercial Input 椰枣害虫的管理:缺乏商业投入
Q2 Agricultural and Biological Sciences Pub Date : 2022-02-01 DOI: 10.1564/v33_feb_02
M. Ansari, Sarah Harding
According to Statista, the global date market was valued at about $13.4 billion in 2019 and is forecast to reach $16.25 billion by 2025. However, this valuable crop is threatened by numerous pests. In fact, the date palm is associated with 132 species of insect and mite pests, which feed on the leaves, roots, trunk, and fruits on the palm, as well as stored dates. The most economically important pests include the red palm weevil, (Rhynchophorus ferrugineus), old world date mite (Oligonychus afrasiaticus), lesser date moth (Batrachedra amydraula), Dubas date bug (Ommatissus lybicus), green pit scale (Palmaspis phoenicis), carob moth (Ectomyelois ceratoniae), date palm longhorn beetle (Jebusaea hammerschmidti) and almond moth (Cadra castellan). It has been estimated that effective curative approaches for red palm weevil infestations alone could result in savings as high as $104 million. Several research groups are working to find effective solutions to control these pests, but as yet no commercial biocontrol products are registered or available for curative control of the palm beetle and larvae. Therefore, a more robust Integrated Pest Management(IPM) system is needed to reduce the pest damage. Commercial formulations include root treatments, insecticide-based capsules that are injected into the trunk, or foliage/fruit sprays. However, chemical insecticides should not be the only solution to the management of date palm pests, especially those concealed inside the trunk or beneath palm tissues, making them difficult to target. This is primarily because chemical insecticides frequently just kill the target pest's natural enemies, while the pests themselves remain protected within the date palm. Several approaches are used but it has also been shown that resistance against a range of commonly used chemical insecticides (profenophos, imidacloprid, chlorpyrifos, cypermethrin, deltamethrin, spinosad, lambda-cyhalothrin, phosphine) develops after extensive use. Resistance ratios as high as 79-fold have been reported, compared with susceptible control pests. Researchers have reported significantly improved populations of natural enemies of target pests in date palm plantations when chemical insecticide use is reduced. Around 90 species of beneficial predators and parasitoids have so far been reported, suggesting that biological control with microbials could be incorporated into a synchronised IPM programme.
根据Statista的数据,2019年全球日期市场价值约为134亿美元,预计到2025年将达到162.5亿美元。然而,这种宝贵的作物受到许多害虫的威胁。事实上,椰枣树与132种昆虫和螨虫有关,它们以椰枣树的叶子、根、树干和果实以及储存的椰枣为食。经济上最重要的害虫包括红棕榈象鼻虫(Rhynchophorus ferrugineus)、旧世界枣螨(Oligonychus afrasiaticus)、小枣蛾(Batrachedra amydraula)、大枣虫(Ommatissus lybicus)、绿坑蚧(Palmaspis phoenicis)、角豆蛾(Ectomyelois ceratoniae)、枣树长角甲虫(Jebusaea hammerschmidti)和杏仁蛾(Cadra castellan)。据估计,仅对红棕象鼻虫侵扰采取有效的治疗方法就可节省高达1.04亿美元。几个研究小组正在努力寻找控制这些害虫的有效办法,但迄今为止还没有注册或可用于治疗性控制棕榈甲虫及其幼虫的商业生物防治产品。因此,需要一个更强大的有害生物综合管理系统来减少有害生物的危害。商业配方包括根部治疗,注射到树干的基于杀虫剂的胶囊,或叶子/果实喷雾。然而,化学杀虫剂不应该是管理枣椰树害虫的唯一解决方案,特别是那些隐藏在树干内或棕榈组织下的害虫,使它们难以被瞄准。这主要是因为化学杀虫剂经常只是杀死目标害虫的天敌,而害虫本身在枣椰树中仍然受到保护。采用了几种方法,但也表明,在广泛使用后,对一系列常用化学杀虫剂(敌敌畏、吡虫啉、毒死蜱、氯氰菊酯、溴氰菊酯、氰氨菊酯、高效氯氰菊酯、膦)产生抗药性。据报道,与易感对照害虫相比,抗性比高达79倍。研究人员报告说,当化学杀虫剂的使用减少时,枣椰树种植园目标害虫的天敌数量显著增加。到目前为止,已经报道了大约90种有益的捕食者和拟寄生虫,这表明可以将微生物的生物防治纳入同步的IPM计划。

Things Will Only Get Worse: Post-brexit Reality is Hitting Farmers Hard 情况只会变得更糟:英国脱欧后的现实严重打击了农民
Q2 Agricultural and Biological Sciences Pub Date : 2022-02-01 DOI: 10.1564/v33_feb_12
Following Brexit, the four countries that make up the UK will each treat basic payments to farmers differently. For farmers in Scotland, Wales and Northern Ireland payments will remain the same – at least for now. For farmers in England, change is coming faster. Bad news can hit you with a bang or it can creep up on you. The changes at Britain's borders had an immediate impact, but for many farmers in England the consequences of losing income from the EU Basic Payment Scheme (BPS) are only now sinking in. For farmers in Scotland, Wales and Northern Ireland payments will remain the same – at least for now. In July, Farmers Weekly (30th July, 2021, p.30) published a farmer survey which found that 95% of farmers received annual basic payment. A little over half get up to £30,000, and for larger farms the sums are considerably higher as the payment depends on the acres farmed. Now that Britain has left the EU, payments for English farmers will be phased out gradually with the last one to be made in 2027. Instead, they can apply for money through the Sustainable Farming Incentive scheme (SFI), one of three programmes under the Government's Environmental Land Management scheme (ELMs). If that sounds complicated that is because it is. ‘Public money for public goods' is Defra's catchy slogan, but at present it is still unclear how much money farmers will eventually be paid and for what – the four-year trial phase of the scheme only began this summer, the general SFI rollout is planned for the middle of next year. So far, only one thing is absolutely clear: ELMs will not be a full substitute for the EU Basic Payment Scheme. At best, farmers will be able to make up about a third of BPS through ELMs. The Farmers Weekly poll reflects what that means: three-quarters of farmers have no idea how their business will survive without BPS. Some 53% said it would be difficult to replace the lost income, with a further 26% unsure if they could. So, what can farmers do to make up for the loss?
英国脱欧后,组成英国的四个国家将分别不同对待向农民支付的基本款项。对于苏格兰、威尔士和北爱尔兰的农民来说,付款将保持不变——至少目前是这样。对于英格兰的农民来说,变化来得更快。坏消息可能会让你大吃一惊,也可能悄悄降临到你身上。英国边境的变化产生了立竿见影的影响,但对英格兰的许多农民来说,失去欧盟基本支付计划(BPS)收入的后果现在才逐渐显现。对苏格兰、威尔士和北爱尔兰的农民来说,支付将保持不变,至少目前是这样。7月,《农民周刊》(2021年7月30日,第30页)发布了一项农民调查,发现95%的农民获得了年度基本工资。一半多一点的人最高可达30000英镑,而对于较大的农场,由于付款取决于耕种的英亩数,因此金额要高得多。现在英国已经脱离欧盟,对英国农民的付款将逐步取消,最后一笔将在2027年支付。相反,他们可以通过可持续农业激励计划(SFI)申请资金,这是政府环境土地管理计划(ELM)下的三个计划之一。如果这听起来很复杂,那是因为它确实如此。“公共产品的公共资金”是Defra朗朗上口的口号,但目前还不清楚农民最终会得到多少钱,以及支付什么费用——该计划的四年试验阶段今年夏天才开始,计划在明年年中全面推出SFI。到目前为止,只有一件事是绝对清楚的:ELM不会完全取代欧盟基本支付计划。充其量,农民将能够通过ELM占BPS的三分之一左右。《农民周刊》的民意调查反映了这意味着什么:四分之三的农民不知道如果没有BPS,他们的企业将如何生存。约53%的人表示很难弥补收入损失,另有26%的人不确定能否弥补。那么,农民能做些什么来弥补损失呢?
