Here, we synthesize current knowledge on exogenous viruses associated with parasitoids, including their diversity, transmission, replication strategies, and infection outcomes. Despite the extensive diversity of parasitoids, our review shows that viruses have been characterized in only 34 species, with 62 RNA and 11 double-stranded DNA viruses identified. We also examine the implications of virus–parasitoid–host interactions for ecological dynamics and biological control, emphasizing how viruses may shape host–parasitoid relationships, competition, and pest suppression.

These disruptions increase the risks of population decline and extirpation in the absence of compensatory responses. Although these processes have been explored in the context of global climate change, other sources of change can threaten populations. Cityscapes generally increase environmental temperature through the retention of heat from impervious surfaces, that is, the urban heat island effect. There are now many studies documenting trait responses to urban heat islands through both plastic and evolutionary mechanisms. Similarly, many other studies have linked urban heat islands to changes in insect community structure within the city footprint. Progress in these research areas has relied heavily on theory and empirical foundations from thermal biology. However, despite a burgeoning literature of temperature effects on fundamental processes that generate (epi)genetic variation and eco-evolutionary dynamics and feedbacks across levels of biological organization from genes to ecosystems, there are large knowledge gaps in how urban warming affects these processes. Here, we summarize the current state of knowledge on the effects of urban heat islands on responses at the level of organismal traits and community structure. We then explore recent advances in temperature effects on genetic and epigenetic sources of variation and eco-evolutionary dynamics to highlight the potential for using cities as venues to understand the role of contemporary warming in each process.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"74 ","pages":"Article 101477"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145707495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat tolerance is the outcome of several physiological processes that induce injury that may ultimately lead to whole-organismal failure and death, and processes counteracting this and facilitating the repair from or prevention of heat injury. This perspective summarizes recent findings and highlights several potentially fruitful avenues through which a more holistic understanding of insect heat stress responses can be achieved. We are of the opinion that further study of mitochondrial mechanisms beyond the classic ‘powerhouse’ paradigm, including a deeper assessment of autophagy flux, may bring fresh insights to several outstanding research questions in insect evolutionary physiology. We therefore call for: i) integration across molecular mechanisms when testing theories of heat tolerance, ii) adopting standardized, transparent approaches across insect taxa (and life-stages) that will facilitate comparative analyses, and iii) a broader integration of experimental assessments of insect heat tolerance within the context of experienced microclimatic conditions.</div></div>","PeriodicalId":11038,"journal":{"name":"Current opinion in insect science","volume":"74 ","pages":"Article 101476"},"PeriodicalIF":4.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145713629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic engineering of mosquitoes requires a profound understanding of mosquito physiology and molecular aspects of host–pathogen interactions. Over the years, several stages of the <em>Plasmodium</em> parasite development within the mosquito have been extensively studied, with many molecular mechanisms successfully elucidated.

Their effectiveness and ubiquitous use across global landscapes are offset by persistent concerns over health and environmental risks. However, such concerns are often biased, patchy, and prone to oversimplification, failing to reflect the complexity of modern anthropogenically altered ecosystems. Today, an ever-expanding diversity of compounds is used — frequently in mixtures subject to chemical interactions — affecting multiple biological processes and interacting organisms. This reality is poorly mirrored in current regulatory frameworks and societal perceptions, which continue to shape research agendas and priorities. Here, we redirect attention beyond the usual targets, moving past conventional pesticides and single natural enemies to shed light on a broad and often-overlooked web of interactions among natural enemies themselves.

Among the various cell death mechanisms, apoptosis is crucial for sculpting tissues, eliminating damaged or infected cells, and limiting pathogen replication. In parallel, autophagy serves as a self-recycling process that facilitates nutrient allocation, stress resilience, and remodeling of larval structures during development but, in specific contexts, can be associated with cell death. Beyond their physiological importance, apoptosis and autophagy have emerged as attractive targets for pest control. To this purpose, two strategies can be envisaged: i) inducing cell death in key tissues using natural or synthetic compounds to compromise insects’ physiology and ii) manipulating apoptotic and autophagic signaling pathways through chemical or genetic tools, such as RNA interference (RNAi) or clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 systems, to impair development and immunity, thus reducing insect survival and fitness. Harnessing these cell death pathways offers promising new avenues for controlling insect pests and vector-borne diseases.
