生态集约化(EI)为实现更可持续的农业系统提供了一条重要的途径,并被越来越多地采用。然而,农场生态集约实践的实施和成功与否可能因景观环境和当地管理实践的不同而有所差异。我们评估了 EI 干预措施(包括两种不同的农业投入制度(大量或少量使用合成杀虫剂和化肥)以及花卉边境作物)如何影响当地天敌生物多样性、害虫丰度和作物产量,以及这些因素如何受到印度普杜切里小农农场 12 块稻田周围景观环境的影响。减少农业投入对整体天敌组合产生了积极影响;然而,对景观因素的反应却各不相同。例如,茧甲虫与较高密度的田边(景观配置)呈负相关。相比之下,蜘蛛是调查中数量最多的一类害虫,但并没有受到任何景观指标的显著影响。此外,害虫丰度在投入减少的田块中最高,但仅存在于没有花卉边际作物的地点。与高投入地相比,低投入地的平均稻谷产量较低,花卉边际作物对高投入地和低投入地的影响相反。在低投入地,有花境作物的地方平均产量要高出 33%。而在高投入地区,花境作物的存在与较低的平均产量(16%)相关。这些研究结果表明,生态集约化实践可为小农作物系统带来益处,但同时也强调,在制定有效的可持续管理实践时,需要考虑地貌环境和当地管理实践的差异。

斑灯蝇,Lycorma delicatula White(半翅目:Fulgoridae),是一种入侵性东南亚跳虫,最近被引入美国东部,通过 "搭便车 "在车辆和货物上沿着人类交通走廊传播。为了更好地了解移动生命阶段在移动过程中的建立风险,了解斑灯蝇移动生命阶段在不同温度下没有食物和水的情况下能存活多长时间至关重要。这项工作报告了斑灯蝇第一、第二和第三龄若虫和成虫在 10-30°C 温度范围内没有食物的情况下的存活情况。在温度<30°C时,第一龄若虫的存活时间长于第二龄或第三龄个体。除 10 和 25°C 外,雌性成虫的存活时间比雄性成虫长约 1 天。在没有食物的情况下,在评估的温度范围内,99% 的雌雄成虫预计会在不到一周的时间内死亡。初生个体最小,存活时间最长,随着温度的升高,它们的存活率呈指数下降。本文提供的数据将为评估各种路径上运输的斑灯蝇活动生命阶段的存活风险提供依据。

植被复杂性和田间管理的时间变化可能会交互影响农业生态系统中捕食者-猎物网络的结构,从而改变捕食者的生物控制潜力。我们研究了作物生长过程中的植被复杂性和管理类型(常规管理与有机管理)如何影响泰国南部雨水灌溉低地水稻生态系统中球织蜘蛛及其猎物的营养网络。具体而言,我们研究了织眶蜘蛛与猎物的组成、猎物选择性和网络结构。总体而言,织眶蜘蛛捕获的主要是与碎屑相关的双翅目、与水生相关的蜉蝣目和半翅目害虫。水稻生长过程中植被复杂性的增加极大地调整了织眶蜘蛛与猎物的网络结构,而田间管理的影响微乎其微。我们的研究结果表明,在水稻生长后期,增加每个猎物分类群的蜘蛛种类数量(猎物脆弱性)可能会加强蜘蛛对包括水稻害虫在内的猎物的自上而下的控制。本研究还强调,在水稻生长季节,随着植被变得更加复杂,水稻生态系统的网络复杂性和稳定性也在增加。未来的实践可以寻找一种方法,在水稻生长早期支持碎屑和水生昆虫的密度,并人为增加栖息地的复杂性,以改善织眶蜘蛛提供的生物防治服务。

开放式研究是科学进步的一个日益完善和重要的框架,已被广泛的学科成功采用。昆虫学在21世纪面临的巨大挑战要求在全球范围内综合证据,这就需要以与开放研究实践采用缓慢不相称的速度和规模开放共享数据和研究。我们概述了这些必要条件以及开放式研究实践如何在各种情况下加强昆虫学研究。我们还通过几个开放式研究实践的具体实例,强调了开放式科学在整个研究生命周期中的整体性,昆虫学家个人可以很容易地采用这些实践。不过,我们认为,促进、整合和鼓励开放式研究的责任,最关键的是要由出版商(包括学术团体)来承担,因为他们已经在邻近领域中广泛采用了开放式研究。昆虫学必须快速发展,成为开放研究转型中的领先学科。

Open research is an increasingly developed and crucial framework for the advancement of science and has seen successful adoption across a broad range of disciplines. Entomology has, however, been slow to adopt these practices compared to many adjacent fields despite ethical and practical imperatives to do so.The grand challenges facing entomology in the 21st century require the synthesis of evidence at global scales, necessitating open sharing of data and research at a pace and scale incompatible with the slow adoption of open research practices. Open science also plays a vital role in fostering trust in research and maximizing use of research outputs, which is ethically crucial for reducing harms to insects.We outline these imperatives and how open research practices can enhance entomological research across a range of contexts. We also highlight the holistic nature of open science across the full research lifecycle through several specific examples of open research practices, which can be adopted easily by individual entomologists.We do, however, argue that the responsibility of promoting, integrating and encouraging open research is most crucially held by publishers, including scholarly societies, which have leveraged widespread adoption in adjacent fields. Entomology must advance quickly to become a leading discipline in the open research transition.

Independent and interactive effects of diet and entomopathogenic microsporidia on an outbreaking forest insect defoliator 食物和昆虫病原微孢子虫对一种爆发性森林昆虫落叶器的独立和交互影响

Insect herbivore diet mediates interactions with entomopathogens, yet this is relatively unexplored for microsporidia. Here, we examine a diet‐mediated tri‐trophic interaction between an outbreaking forest defoliator, forest tent caterpillar (FTC) Malacosoma disstria Hübner and Nosema sp. microsporidia.We conducted two experiments where diet quality was manipulated by incorporating lyophilized aspen (Populus tremuloides Michaux) foliage into an artificial diet, which was compared to a standard artificial diet. Diet quantity varied between fully fed and partially starved conditions, simulating an outbreak scenario. Microsporidia infection occurred naturally or was induced via experimental inoculation. We assessed FTC survival, microsporidia infection and load, and sublethal effects of treatments on FTC traits.Plant secondary metabolite concentrations in aspen‐augmented diets varied between experiments. In Experiment 1, the aspen‐augmented diet contained lyophilized aspen foliage with low concentrations of secondary metabolites, which increased FTC survival and reduced microsporidia infection. Diet quality and infection load also interactively influenced adult wing traits in Experiment 1. In Experiment 2, the aspen‐augmented diet contained lyophilized aspen foliage with higher concentrations of secondary metabolites, which negatively affected FTC. No diet‐mediated interactions with microsporidia were observed in Experiment 2.Diet quality (Experiments 1 and 2), diet quantity (Experiment 2) and microsporidia infection (Experiments 1 and 2) directly influenced FTC survival and/or had sublethal effects on FTC that may have cascading effects on population dynamics and dispersal.We demonstrated that diet quality can mediate interactions between FTC and microsporidia, but these interactions depend on the defensive chemistry of the FTC diet. To our knowledge, this is the first study to report diet‐mediated interactions between an outbreaking forest pest and microsporidia and one of only a few studies to examine this tri‐trophic interaction among Lepidoptera.
昆虫食草动物的食性介导了昆虫病原体之间的相互作用,但对于微孢子虫来说,这一点还相对缺乏研究。我们进行了两项实验,通过将冻干杨树(Populus tremuloides Michaux)叶片添加到人工饲料中来操纵饲料质量,并将其与标准人工饲料进行比较。日粮数量在完全喂养和部分饥饿条件下变化,模拟疫情爆发的情景。小孢子虫感染会自然发生或通过实验接种诱发。我们评估了FTC的存活率、微孢子虫感染和负荷以及处理对FTC性状的亚致死效应。在实验 1 中,杨树添加的日粮含有冻干的杨树叶片,次生代谢物浓度较低,这提高了 FTC 的存活率并降低了微孢子虫的感染率。在实验 1 中,日粮质量和感染量也会对成虫翅膀特征产生交互影响。在实验 2 中,杨树强化日粮含有二次代谢物浓度较高的冻干杨树叶,这对 FTC 有负面影响。饮食质量(实验 1 和 2)、饮食数量(实验 2)和微孢子虫感染(实验 1 和 2)直接影响 FTC 的存活和/或对 FTC 产生亚致死效应,可能会对种群动态和扩散产生连带效应。据我们所知,这是首次报道爆发性森林害虫与微孢子虫之间由食物介导的相互作用,也是仅有的几项研究之一,研究了鳞翅目昆虫之间的这种三营养相互作用。

简介东方果蝇 Bactrocera dorsalis(Hendel,1912 年)(双翅目,Tephritidae)是印度-亚洲地区特有的害虫,是世界上最具入侵性和多食性的水果和蔬菜害虫之一(White & Elson-Harris, 1992)。这种果蝇是 Bactrocera 属中寄主范围最广的种类,已记录到其寄主植物超过 500 种(Allwood 等人,1999 年;Clarke 等人,2005 年;Liquido 等人,2015 年)。其广泛的寄主范围使其能够全年在空间和时间上维持种群数量。Bactrocera dorsalis 会对作物造成损害,从而产生重大经济影响并导致出口市场的丧失。例如,在一些栽培品种(如芒果和番石榴)中,高达 100%的果实会受到虫害(Badii 等人,2015 年)。Bactrocera dorsalis 具有很强的竞争力,可取代已确定的表皮蠹蛾物种(如 Ceratitis sp.或其他 Bactrocera sp.(Sauders,1841 年))的生态位(Duyck 等人,2004 年;Ekesi 等人,2016 年;Hassani,2017 年;Moquet 等人,2021 年;Mwatawala 等人,2006 年;Rasolofoarivao 等人,2021 年)。该物种经常成为受入侵地区的主要果蝇物种。在马约特岛,背腹果蝇于 2007 年首次被记录(De Meyer 等人,2010 年,2012 年),但其寄主范围、侵染率以及与其他物种的相互作用仍有待调查。在马约特岛,共记录到九种 Tephritidae,其中包括一种群岛特有物种 Dacus etiennellus Munro, 1984(De Meyer 等人,2012 年)。除 B. dorsalis 外,岛上已知的外来果蝇害虫还包括 Dacus ciliatus Loew, 1862(通常为害葫芦科植物)(Ryckewaert 等人,2010 年)、Neoceratitis cyanescens(Bezzi, 1923)(为害茄科植物)以及多食性物种 Ceratitis capitata(Wiedemann, 1824)(De Meyer 等人,2012 年;Franck & Delatte, 2020 年)。马约特岛还报告了其他果蝇物种,包括危害葫芦科植物的 Dacus bivittatus(Bigot,1858 年)和 Dacus vertebratus Bezzi,1908 年;以及 Tririthhrum nigerrimum(Bezzi,1913 年)和 Ceratitis malgassa(Munro,1939 年),它们危害多种不同的寄主植物科(De Meyer 等人,2012 年;Rasolofoarivao 等人,2021 年)。农业是马约特的主要活动之一,为约 60,000 人提供生计,占总人口的三分之一(马约特 DAAF,2021 年)。岛上消费的新鲜水果和蔬菜中,约 80% 由当地农业提供(马约特岛农业部/马约特岛农业发展局,2017 年)。大多数农民使用被称为 "Mahorais 花园 "的传统农业和食品系统。这些都是小规模的农林系统,具有多层次性,包含各种文化关联(马约特岛农业和林业发展部,2016 年)。这些系统通常包括果树(芒果、橘子等)、果叶蔬菜、根茎和块茎、芳香植物(香草、依兰等)、饲料植物和其他粮食作物。我们的目的是确定马约特岛具有重要经济意义的果蝇的寄主范围,并确定攻击表皮蝇类的寄生虫的多样性。我们特别关注 B. dorsalis,它是岛上最近记录到的入侵物种。为了研究果蝇侵扰随时间的变化,我们比较了两个时期的侵扰率:果蝇入侵后的 5-7 年和 12-14 年。
