The fall armyworm, Spodoptera frugiperda, a moth originating from tropical and subtropical America, has recently become serious pest of cereals in sub-Saharan Africa. Biological control offers an economically environmentally safer alternative to synthetic insecticides that are being used for the management this pest. Consequently, various biological options considered, including introduction Telenomus remus, main egg parasitoid S. frugiperda Americas, where it is already augmentative programmes. During surveys South, West, East Africa, parasitized masses were collected, emerged parasitoids identified through morphological observations molecular analyses as T. remus. presence remus Africa at least five countries provides great opportunity develop methods register against frugiperda. Surveys should be carried out throughout assess present distribution on continent, could re-distributed regions absent, following national international regulations. Classical focus importation larval Americas.

Abstract The world's forests face unprecedented threats from invasive insects and pathogens that can cause large irreversible damage to the ecosystems. This threatens capacity provide long‐term fiber supply ecosystem services range carbon storage, nutrient cycling, water air purification, soil preservation maintenance of wildlife habitat. Reducing threat forest alien species requires vigilant biosurveillance, process gathering, integrating, interpreting, communicating essential information about pest pathogen achieve early detection warning enable better decision‐making. is challenging due diversity pests need be identified, diverse pathways introduction, difficulty in assessing risk establishment.

Unravelling the invasion history of the Asian tiger mosquito in Europe

Molecular Ecology, Год журнала: 2019, Номер 28(9), С. 2360 - 2377

Multiple introductions are key features for the establishment and persistence of introduced species. However, little is known about contribution genetic admixture to invasive potential populations. To address this issue, we studied recent invasion Asian tiger mosquito (Aedes albopictus) in Europe. Combining genome-wide single nucleotide polymorphisms historical knowledge using an approximate Bayesian computation framework, reconstruct colonization routes establish demographic dynamics invasion. The Europe involved at least three independent Albania, North Italy Central that subsequently acted as dispersal centres throughout We show topology human transportation networks shaped histories with being main Introduction modalities conditioned levels diversity invading populations, genetically diverse admixed populations promoted more secondary have spread farther than single-source invasions. This genomic study provides further crucial insights into a general understanding role by modern trade driving biological

The evolutionary dynamics of biological invasions: A multi‐approach perspective

Biological invasions, the establishment and spread of non-native species in new regions, can have extensive economic environmental consequences. Increased global connectivity accelerates introduction rates, while climate land-cover changes may decrease barriers to invasive populations spread. A detailed knowledge invasion history, including assessing source populations, routes spread, number independent introductions, effects genetic bottlenecks admixture on success, adaptive potential, further is crucial from an applied perspective mitigate socioeconomic impacts species, as well for addressing fundamental questions evolutionary dynamics process. Recent advances genomics together with development geographic information systems provide unprecedented large datasets at local scales link population genomics, landscape ecology, distribution modeling into a common framework study Although factors underlying invasiveness been extensively reviewed, analytical methods currently available optimally combine molecular data inferring demographic parameters predicting spreading are still under development. In this review, we focus few recent insect studies that different approaches show how integrating genetic, observational, ecological, pave way more integrative biological science. We guidelines invasions each step process, conclude benefits all types up-to-date tools research areas single framework.

Deciphering the worldwide invasion of the Asian long‐horned beetle: A recurrent invasion process from the native area together with a bridgehead effect

Molecular Ecology, Год журнала: 2019, Номер 28(5), С. 951 - 967

Опубликована: Янв. 24, 2019

Retracing introduction routes is crucial for understanding the evolutionary processes involved in an invasion, as well highlighting invasion history of a species at global scale. The Asian long-horned beetle (ALB) Anoplophora glabripennis xylophagous pest native to Asia and invasive North America Europe. It responsible severe losses urban trees, both its invaded ranges. Based on historical genetic data, several hypotheses have been formulated concerning history, including possibility multiple introductions from zone secondary dispersal within areas, but none formally tested. In this study, we characterized structure ALB ranges using microsatellites. order test different scenarios, used approximate Bayesian "random forest" algorithm together with traditional population genetics approaches. strong differentiation observed area was not geographically structured, suggesting complex migration events that were probably human-mediated. Both populations had low diversity, characteristic did prevent success invasions. Our results highlight complexity pathways insect pests. Specifically, our findings indicate might be repeatedly introduced their range, they emphasize importance multiple, human-mediated successful Finally, demonstrate can spread across continents following bridgehead path, which may acted source another invasion.

Bridgehead effect and multiple introductions shape the global invasion history of a termite

Communications Biology, Год журнала: 2021, Номер 4(1)

Опубликована: Фев. 12, 2021

Abstract Native to eastern Asia, the Formosan subterranean termite Coptotermes formosanus (Shiraki) is recognized as one of 100 worst invasive pests in world, with established populations Japan, Hawaii and southeastern United States. Despite its importance, native source(s) C. introductions their pathway out Asia remain elusive. Using ~22,000 SNPs, we retraced invasion history this species through approximate Bayesian computation assessed consequences on genetic patterns demography. We show a complex history, where an initial introduction resulted from two distinct events Hong Kong region. The admixed Hawaiian population subsequently served source, bridgehead, for US. A separate event southcentral China occurred Florida showing admixture first introduction. Overall, these findings further reinforce pivotal role bridgeheads shaping distributions Anthropocene illustrate that global distribution has been shaped by multiple China, which may have prevented possibly reversed loss diversity within range.

Abstract The North American oak lace bug feeds on leaves of ‘white oaks” in its native range. In Europe, it was first discovered northern Italy 2000. recent years, has subsequently spread rapidly and population outbreaks have been observed several European countries. the present study, we summarize steps expansion. To predict potential host range, checked 48 species 20 sentinel gardens seven countries between 2013 2018. total, 27 were recorded as suitable hosts; 13 them are globally new ones, 23 out 29 section Quercus (∼ white oaks, an intrageneric taxonomic unit within genus ), including Asian to Japan, Korea China, four five Cerris (another same genus), accepted hosts. None Lobatae (red oaks) or Ilex group accepted. Host records also collected forest stands 10 We found 11 that infested. Outbreak populations most commonly robur , frainetto petraea cerris comprising widespread outstandingly important oaks Europe. Based our findings, conclude hosts for Europe Asia.
