Spongy moths from Europe and Asia: Who could have higher invasion risk in North American?

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(5), P. e0320598 - e0320598

North American forest systems are significantly impacted by spongy moths ( Lymantria dispar Linnaeus). It is unclear, nevertheless, how the invasion risks of from Asia and Europe in relative to each other. In this study, we compared potential ranges (ASM) those (ESM) America, investigated range shifts between America (NASM) ASM ESM. ESM would occupy larger than NASM, i.e., 7.16 6.98 times, respectively. Thus, one should not undervalue invasive posed Europe. Compared ESM, displayed America. likely due ASM’s tolerance more variable climates. Consequently, even though was recently introduced it’s possible that former has higher risk American.

Range‐wide population genomics of the spongy moth, Lymantria dispar (Erebidae): Implications for biosurveillance, subspecies classification and phylogeography of a destructive moth

Evolutionary Applications, Journal Year: 2023, Volume and Issue: 16(3), P. 638 - 656

The spongy moth, Lymantria dispar, is an irruptive forest pest native to Eurasia where its range extends from coast and overspills into northern Africa. Accidentally introduced Europe in Massachusetts 1868-1869, it now established North America considered a highly destructive invasive pest. A fine-scale characterization of population genetic structure would facilitate identification source populations for specimens intercepted during ship inspections enable mapping introduction pathways help prevent future incursions novel environments. In addition, detailed knowledge L. dispar's global provide new insight the adequacy current subspecies classification system phylogeographic history. To address these issues, we generated >2000 genotyping-by-sequencing-derived SNPs 1445 contemporary sampled at 65 locations 25 countries/3 continents. Using multiple analytical approaches, identified eight subpopulations that could be further partitioned 28 groups, achieving unprecedented resolution this species' structure. Although reconciliation between groupings three currently recognized proved challenging, our data confirmed circumscription japonica Japan. However, cline observed across continental Eurasia, dispar asiatica East Asia d.

Importantly, moths Caucasus/Middle displayed high enough distances other warrant their consideration separate dispar. Finally, contrast with earlier mtDNA-based investigations Caucasus place origin, analyses suggest evolutionary cradle, spread Central Japan through Korea.

Abstract Background Deciduous forests in eastern North America experienced a widespread and intense spongy moth ( Lymantria dispar ) infestation 2021. This study quantified the impact of this on carbon (C) cycle across Great Lakes region Canada, utilizing high-resolution (10 × 10 m 2 Sentinel-2 satellite remote sensing images eddy covariance (EC) flux data. Study results showed significant reduction leaf area index (LAI) gross primary productivity (GPP) values deciduous mixed Results Remote derived, growing season mean LAI (mixed) were 3.66 (3.18), 2.74 (2.64), 3.53 (2.94) −2 2020, 2021 2022, respectively, indicating about 24 (14)% LAI, as compared to pre- post-infestation years. Similarly, GPP 1338 (1208), 868 (932), 1367 (1175) g C , respectively showing 35 (22)% induced forests, when upscaled whole (178,000 km ), resulted 21.1 (21.4) Mt loss 2020 (2022), respectively. It shows large scale losses caused by Canadian region. Conclusions The methods developed offer valuable tools assess quantify natural disturbance impacts regional balance forest ecosystems integrating field observations, data models. will also help developing sustainable management practices achieve net-zero emission goals through nature-based climate change solutions.

Genetics of flight in spongy moths (Lymantria dispar ssp.): functionally integrated profiling of a complex invasive trait

BMC Genomics, Journal Year: 2024, Volume and Issue: 25(1)

Published: May 31, 2024

Abstract Background Flight can drastically enhance dispersal capacity and is a key trait defining the potential of exotic insect species to spread invade new habitats. The phytophagous European spongy moths (ESM, Lymantria dispar ) Asian (ASM; multi–species group represented here by L. d. asiatica japonica ), are globally invasive that vary in adult female flight capability—female ASM typically capable, whereas ESM flightless. Genetic markers capability would supply powerful tool for profiling these at any intercepted life stage. To assess functional complexity moth identify capability, we used multiple genetic approaches aimed capturing complementary signals putative flight–relevant divergence between ASM: reduced representation genome–wide association studies, whole genome sequence comparisons, developmental transcriptomics. We then judged candidacy flight–associated genes through analyses addressing proximate demands salient features ecological context evolution. Results Candidate gene sets were non–overlapping across different approaches, with only nine annotations shared pair approaches. detected an array themes collectively suggest lineages has coincided evolutionary differentiation aspects development, execution, surrounding history. Overall, our results indicate evolution shaped or been influenced large functionally broad network traits. Conclusions Our study identified suite suited exploration architecture flight, validation purposes. This work illustrates how combined phenotypically targeted help characterize genetically complex

The spongy moth, Lymatria dispar, is a classic example of an invasive pest accidentally introduced from Europe to North America, where it has become one the most serious forest defoliators, as in its native range. present study was aimed at (i) identifying current northern limit L. dispar's Eurasian range and exploring northward expansion Canada using pheromone trap data, (ii) comparing populations with those central southern regions respect male flight phenology, sums effective temperatures (SETs) above 7 °C threshold necessary for development adult stage, heat availability. We show that dispar Eurasia now reaches 61st parallel, comparisons historical data identify average speed spread 50 km/year. also document progression Canada, actual boundary remains be identified. median date does not vary greatly between moth despite climate differences. Synchronization different latitudes associated acceleration larval populations. Similar changes developmental rate along latitudinal gradient have been documented American Thus, we argue this feature moths poses significant threat America terms enhanced risks rapid expansion.

Published: Nov. 1, 2024

ABSTRACT Biological invasions pose significant threats to ecological and economic stability, with invasive pests like the Asian longhorned beetle ( Anoplophora glabripennis Motschulsky, ALB) causing substantial damage forest ecosystems. Effective pest management relies on comprehensive knowledge of insect's biology invasion history. This study uses genomics address these gaps inform existing biosurveillance frameworks. We used 2768 genome‐wide single nucleotide polymorphisms compare A. populations in North America, using genomic variation trace their sources spread patterns, thereby refining our understanding this species' found that most American infestations were distinct, resulting from multiple independent introductions native range. Following introduction, all experienced a genetic bottleneck which was followed by population expansion, few also showing secondary satellite infestations. Our provides foundation for genome‐based tool can be clarify origin intercepted individuals, allowing regulatory agencies strengthen biosecurity measures against beetle.
