Published: June 25, 2023

Anthropogenic challenges, particularly climate change-associated factors, are strongly impacting the behavior, distribution, and survival of insects. Yet how these changes affect pests such as Drosophila suzukii, a cosmopolitan pest soft-skinned small fruits, remains poorly understood. This polyphagous is chill-susceptible, with cold temperatures causing multiple stresses, including desiccation starvation, also challenging immune system. Since invasion Europe United States America in 2009, it has been rapidly spreading to several European American countries (both North South American) African Asian countries. However, globalization global warming allowing an altitudinal latitudinal expansion species, thus colonization colder regions. review explores D. suzukii adapts survive during seasons. We focus on overwintering strategies behavioral adaptations migration or sheltering, seasonal polyphenism, reproductive adaptations, well metabolic transcriptomic response cold. Finally, we discuss continuation change may promote ability this species spread, what mitigation measures could be employed overcome cold-adapted suzukii.

Gut health is essential to the overall well-being of a human being due its implication on digestion, performance immune system, and nutritional absorption. The gut microbiota represents an intricate ecology bacteria, fungi, viruses, important in regulating response maintaining intestinal health. Fruit-based diets have developed as constituent health, current studies highlight nutrition modulating composition activity. Rich fiber, polyphenols, vitamins, antioxidants, fruits also expand immunological function, subordinate inflammation stomach, boost microbial diversity. article reviews benefits fruit-derived dietary fibers, which assist prebiotics fostering development beneficial decreasing inflammation. These antioxidants include flavonoids carotenoids, whose immunomodulatory properties are under investigation for therapeutic use autoimmune diseases, infections, inflammatory bowel disease (IBD). Some particular interest bananas, apples, citrus, berries, consistently shown their gastrointestinal effects.

Metabolic consequences of various fruit-based diets in a generalist insect species

eLife, Journal Year: 2023, Volume and Issue: 12

Published: June 6, 2023

Most phytophagous insect species exhibit a limited diet breadth and specialize on few or single host plant. In contrast, some display remarkably large breadth, with plants spanning several families many species. It is unclear, however, whether this phylogenetic generalism supported by generic metabolic use of common chemical compounds (‘metabolic generalism’) alternatively distinct uses diet-specific (‘multi-host specialism’)? Here, we simultaneously investigated the metabolomes fruit diets individuals generalist species, Drosophila suzukii , that developed them. The direct comparison consumers enabled us to disentangle fate rarer dietary compounds. We showed consumption biochemically dissimilar resulted in canalized, response from individuals, consistent hypothesis. also metabolites, such as those related particular color, odor, taste diets, were not metabolized, rather accumulated consumer even when probably detrimental fitness. As result, while mostly similar across detection their was straightforward. Our study thus supports view may emerge passive, opportunistic various resources, contrary more widespread views an active role adaptation process. Such passive stance towards chemicals, costly short term, might favor later evolution new specializations.

Insects’ host preferences are regulated by multiple factors whose interactions only partly understood. Here we make use of an in-depth, untargeted metabolomic approach combining molecular networking (MN) and supervised Analysis variance Multiblock Orthogonal Partial Least Squares (AMOPLS) to untangle egg-laying Drosophila suzukii , invasive, highly polyphagous destructive fruit pest originating from Southeast Asia. Based on behavioural experiments in the laboratory as well field observation, selected eight genetically related Vitis vinifera cultivars (e.g., Ancellotta, Galotta, Gamaret, Gamay, Gamay précoce, Garanoir, Mara Reichensteiner) exhibiting significant differences their susceptibility toward D. . The two most least attractive red were chosen for further analyses grape skins. combination MN statistical AMOPLS findings with semi-quantitative detection information enabled us identify flavonoids interesting markers attractiveness four studied towards Overall, dihydroflavonols accumulated unattractive cultivars, while richer flavonols.

Abstract Climate change and globalization are accelerating biological invasions, highlighting the urgent need to understand adaptation mechanisms in invaded environments improve management strategies. Genomic data can provide insights into of invasive species through Genotype-Environment Association (GEA) studies, identifying genes processes associated with invasion success, more globally estimate genetic (mal)adaptation new by calculating Offset (GO) statistics. In this study, we investigate crop pest Drosophila suzukii using novel genomic resources statistical methods. We rely on a chromosome-level genome assembly dataset representing 36 populations, combining both publicly available newly generated pooled individual sequencing data, which analyzed an enhanced version B ay P ass software, tailored for such hybrid datasets. identify limited number regions supporting hypothesis polygenic architecture underlying adaptive traits. Using GEA incorporating 28 environmental covariates, further GO between source areas gain insight challenges faced D. during past invasions.
