Invasive social wasps and hornets pose significant threats to biodiversity, ecosystem services, and animal and human health. This review evaluates recent advances in invasive wasp and hornet management using criteria developed for assessing the feasibility of eradication and control programmes. I emphasise the importance and methods of early detection, citizen science, public involvement, and the role of advanced technologies, such as artificial intelligence, drones, and radio telemetry for nest detection. Toxic baits remain a vital tool for population suppression, although improvements in their efficacy and selectivity are needed to mitigate nontarget impacts. The review explores the development of targeted control tools, including emerging biological and genetic control methods, which promise potential solutions but require careful consideration of ecological risks. Genetic interventions include gene drives that offer future potential for sustained long-term control but require robust regulatory frameworks. Global collaboration to standardise management is essential, as invasion and control efforts in one region can affect neighbouring countries. The integration of international best practices with legal frameworks, public engagement, and adaptive management strategies will be critical to the success of future management programmes.

Reproductive organs are among the most variable and rapidly evolving structures in the animal kingdom, probably due to sexual selection. In insects, the diverse morphology of male genitalia is often one of the few visible characteristics that can reliably distinguish closely related species, making it crucial for taxonomic classification. Consistent with this, males of the model organism Drosophila melanogaster and its closely related species display remarkable variations in genital morphology. This variation has made the male genitalia of Drosophilids an invaluable system for dissecting the genetic and developmental pathways responsible for morphological evolution, providing insights into how new structures emerge and how gene regulatory networks are co-opted during this process. In this review, we highlight recent studies that have uncovered developmental processes, novel genes, and regulatory networks that contribute to the morphogenesis and evolution of these extraordinary structures. These studies mark a significant advancement in our understanding of the mechanisms driving the evolution of complex organs.

The roles of viruses in tephritid pest multitrophic interactions and an outlook for biological control

Tephritid fruit fly pests remain a considerable problem for agricultural fruit production around the world. New control methods that do not rely on synthetic insecticides are increasingly desirable to diversify tephritid pest management programs. Biological control through the release of parasitoid wasps has historically provided effective suppression of fruit fly pests, although molecular factors that influence the success of fruit fly parasitoids are understudied. Microbes have been demonstrated to facilitate myriad interactions between insects and their environment and have been the subject of recent investigation within tephritids. Specifically, the diversity and function of viruses found within fruit flies and associated parasitoids is an emerging field of research that has the potential to deepen our understanding of previously hidden factors that facilitate sustainable pest control. Most work to date has focused on identifying resident viral communities within fruit flies using metagenomic and metatranscriptomic sequencing approaches. Additionally, a growing body of evidence has revealed a multitude of functional dynamics that viruses have with fruit fly hosts, including vertically transmitted commensal viruses and parasitoid-vectored pathogens. Heritable viruses transmitted by fruit fly parasitoids, in particular, have been shown to play prominent roles in fruit fly multitrophic interactions, in which viral infection can shape the survival rate and host range of infected parasitoids. Furthermore, at least one parasitoid virus represents a lethal pathogen to a wide range of fruit fly pest species. Parasitoid viruses could therefore present novel opportunities to leverage natural antagonistic interactions for fruit fly pest control innovations.

The transition to flying insects: lessons from evo-devo and fossils 向飞虫的转变：从进化和化石中得到的教训。

Insects are the only arthropod group to achieve powered flight, which facilitated their explosive radiation on land. It remains a significant challenge to understand the evolutionary transition from nonflying (apterygote) to flying (pterygote) insects due to the large gap in the fossil record. Under such a situation, ontogenic information has historically been used to compensate for fossil evidence. Recent evo-devo studies support and refine a paleontology-based classical hypothesis that an ancestral exite incorporated into the body wall contributed to the origin of insect wings. The modern hypothesis locates an ancestral precoxa leg segment with an exite within the hexapod lateral tergum, reframing the long-standing debate on the insect wing origin. A current focus is on the contributions of the incorporated exite homolog and surrounding tissues, such as the pleuron and the medial bona fide tergum, to wing evolution. In parallel, recent analyses of Paleozoic fossils have confirmed thoracic and abdominal lateral body outgrowths as transitional wing precursors and suggested their possible role as respiratory organs in aquatic or semiaquatic environments. These recent studies have revised our understanding of the transition to flying insects. This review highlights recent progress in both evo-devo and paleontology, and discusses future challenges, including the evolution of metamorphic development.

昆虫是唯一实现动力飞行的节肢动物，这有助于它们在陆地上产生爆炸性的辐射。由于化石记录的巨大空白，了解从非飞行昆虫（翼虫）到飞行昆虫（翼虫）的进化转变仍然是一个重大挑战。在这种情况下，个体成因信息历来被用来弥补化石证据。最近的进化研究支持并完善了一个基于古生物学的经典假设，即一个祖先的出口合并到体壁中，有助于昆虫翅膀的起源。现代假说定位了祖先的前叶腿段，在六足动物的外侧三节中有一个出口，重新定义了关于昆虫翅膀起源的长期争论。目前的焦点是合并的出口同源物和周围组织，如胸膜和内侧真核，对翅膀进化的贡献。与此同时，最近对古生代化石的分析也证实了胸腹侧体的生长是过渡翼的前体，并表明它们在水生或半水生环境中可能是呼吸器官。这些最近的研究改变了我们对昆虫向飞行昆虫过渡的理解。本文综述了演化-devo和古生物学的最新进展，并讨论了未来的挑战，包括变质发育的演变。

Humans and insects inhabit very different perceptual worlds, so human experimenters need to be aware of their perceptual biases when investigating insect behaviour. In applied entomology, human perceptual biases have been a barrier to the rational design, manufacture, and improvement of pest control devices that effectively exploit insect visual behaviour. This review describes how the influence of human perceptual bias on this area of applied entomology is being reduced by our expanding understanding of insect visual perception and use of visual modelling methods and highlights several important challenges that are yet to be overcome.

人类和昆虫生活在非常不同的感知世界，因此人类实验者在研究昆虫行为时需要意识到他们的感知偏差。在应用昆虫学中，人类的感知偏差已经成为合理设计、制造和改进有效利用昆虫视觉行为的害虫控制装置的障碍。这篇综述描述了如何通过我们对昆虫视觉感知的扩展理解和视觉建模方法的使用来减少人类感知偏见对应用昆虫学这一领域的影响，并强调了几个尚未克服的重要挑战。

Plants and invertebrates use chemical signals and cues to construct information about their environment. It is well reviewed that chemical signals play key roles in interactions between conspecific insects, such as sex pheromones for finding mates, and that plants transmit chemical signals to recruit natural enemies that kill herbivores. However, it is also known that chemicals emitted by natural enemies can influence insect herbivore physiology and behavior. The detection of chemical cues associated with the presence of natural enemies can influence herbivore movement, feeding, and reproduction, which may limit the damage herbivores inflict on their host plants. Plants detect chemical cues associated with herbivores, but less is known about whether plants also detect chemical cues of natural enemies or how this detection affects plant defense responses. In this review, we highlight what is known about how natural enemy chemical cues directly affect herbivores, how natural enemy cues indirectly affect herbivores through changes in host plant defenses, and we discuss the evolutionary ecology of plant and herbivore responses to natural enemy cues. Finally, we consider application of these concepts for insect pest management. Improving our understanding of how natural enemy chemical cues mediate multitrophic interactions provides a great opportunity for future exploration.

Condensed Abstract

Plants and invertebrates use chemical signals and cues to construct information about their environment. Detection of chemical cues from natural enemies can influence herbivore behavior and reduce herbivory. Plants detect chemical cues associated with herbivores, but less is known about whether plants detect cues of natural enemies or how detection affects plant defense responses. Here, we highlight what is known about how natural enemy chemical cues directly affect herbivores and how natural enemy cues indirectly affect herbivores through changes in plant defenses. We discuss the evolutionary ecology of plant and herbivore responses to natural enemy cues and consider applications for pest management.

植物和无脊椎动物利用化学信号和线索来构建有关其环境的信息。化学信号在同种昆虫之间的相互作用中起着关键作用，如寻找配偶的性信息素，以及植物传递化学信号来招募天敌杀死食草动物。然而，我们也知道天敌释放的化学物质会影响食草昆虫的生理和行为。检测与天敌存在相关的化学线索可以影响食草动物的运动、摄食和繁殖，从而限制食草动物对其寄主植物造成的伤害。植物可以探测到与食草动物有关的化学信号，但对于植物是否也能探测到天敌的化学信号，或者这种探测如何影响植物的防御反应，人们知之甚少。在这篇综述中，我们重点介绍了天敌化学信号是如何直接影响食草动物的，天敌信号是如何通过宿主植物防御的变化间接影响食草动物的，并讨论了植物和食草动物对天敌信号的反应的进化生态学。最后，我们讨论了这些概念在害虫管理中的应用。提高我们对天敌化学线索如何介导多营养相互作用的理解，为未来的探索提供了很好的机会。摘要：植物和无脊椎动物利用化学信号和线索构建环境信息。检测天敌的化学信号可以影响食草动物的行为，减少食草动物的数量。植物能探测到与食草动物有关的化学信号，但对于植物是否能探测到天敌的信号，以及这种信号如何影响植物的防御反应，人们知之甚少。在这里，我们重点介绍了已知的天敌化学信号如何直接影响食草动物，以及天敌信号如何通过植物防御的变化间接影响食草动物。我们讨论了植物和草食动物对天敌线索的反应的进化生态学，并考虑了害虫管理的应用。

Animals are exposed to changes in their environmental conditions daily. Such changes will become increasingly more erratic and unpredictable with ongoing climate change. Responses to changing environments are influenced by the genetic architecture of the traits under selection and modified by a range of physiological, developmental, and behavioural changes resulting from phenotypic plasticity. Furthermore, the interactions between multiple environmental stressors to which organisms are exposed can generate unexpected phenotypic responses. Understanding how genetic and plastic variation contributes to the response to combined environmental stress will be key to predicting how animals will cope with climate change and ultimately will define their ability to persist. Here, we review the approaches used to explore how animals respond to combined stressors, specifically nutrition and temperature, the physiological mechanisms that underlie such plastic responses, and how genetic variation alters this plasticity.

Insect populations are declining globally, with multiple potential drivers identified. However, experimental data are needed to understand their relative contributions. We highlight the sublethal effects of pesticides at field-relevant concentrations, often overlooked in standard environmental risk assessments (ERA), as significant contributors to these declines. Behavior, as an easily monitored high-level phenotype, reflects alterations at various phenotypic levels. We propose incorporating behavioral assays with AI-based analytical methods into ERA protocols to better assess the safety of molecules intended for large-scale field use. This approach aims to safeguard food supplies and protect vital ecosystems in the future.

全球昆虫数量正在下降，已经确定了多种潜在的驱动因素。然而，需要实验数据来了解它们的相对贡献。我们强调了农药在田间相关浓度下的亚致死效应，这在标准环境风险评估（ERA）中经常被忽视，是导致这些下降的重要因素。行为作为一种易于监测的高水平表型，反映了不同表型水平的改变。我们建议将基于人工智能的行为分析方法纳入ERA协议，以更好地评估用于大规模现场使用的分子的安全性。这种方法旨在保障未来的粮食供应和保护重要的生态系统。
