Ambrosia beetles of the Euwallacea fornicatus (Eichhoff, 1868) species complex are emerging tree pests, responsible for significant damage to orchards and ecosystems around world. The comprises seven described species, all which nearly identical. Given that morphology-defined boundaries have been ambiguous, historically, there has much disagreement on validity, was compounded by presumed loss type series E. fornicatus. recently reviewed using morphometrics associate specimens clades...
Abstract The ambrosia beetle Euwallacea fornicatus Eichhoff sensu lato is a complex of genetically divergent emerging pests responsible for damages to tree industries and ecosystems around the world. All lineages within species are currently considered morphologically identical, presenting problems their delineation highlighting shortcomings concepts based solely on type-specimen morphology. objectives this work were 1) broaden geographic sampling E. in Asia, 2) reconstruct relationships...
The plantation and natural forests of South America have been highly impacted by native exotic pests in recent decades. interaction emerging invasive pests, climate change, timber markets will define the region’s forests, with significant but uncertain ecological changes economic losses expected. Southern Cone Forest Health Group (SCFHG), a joint ad hoc initiative run forest health professionals from Argentina, Brazil, Chile, Uruguay, aims to strengthen relationships between forestry...
Research Highlights: Sentinel-2 Normalized Difference Vegetation Index (NDVI) products show greater potential to detect indications of disturbance by bark beetles in the southeastern US than Moderate Resolution Imaging Spectroradiometer (MODIS), as high spatiotemporal heterogeneity forest land prevents its deployment at current resolution. Background and Objectives: Remote sensing technologies have been an essential tool disturbances caused insect pests through spectral trait variation. In...
Abstract Forested wetlands support diverse biota and provide a wide range of ecosystem services. Archips goyerana Kruse (Lepidoptera: Tortricidae) is native pest that defoliates baldcypress (Taxodium distichum var. (L.) Rich.; Cupressaceae) pondcypress imbricarium (Nuttall); Croom), 2 keystone trees throughout forested the southeastern United States. Outbreaks A. have been isolated to Louisiana, where they caused reduced growth, crown dieback, limited tree death. However, aerial detection...
The invasive ambrosia beetle Euwallacea fornicatus (Eichhoff, 1868) poses a significant threat to forests sensu latu in South America. Uruguay marked the third regional record since 2022, following infestations Brazil and Argentina. pest’s distribution now spans ~ 3,500 km of coastline, highlighting its adaptability diverse climates vulnerability urban ecosystems. Currently, two started foci distant 500 each other: Rivera, northern city bordering with an established population Montevideo,...
<title>Abstract</title> Global trade and the spread of non-native host plants are driving introduction forest insects to new regions, often causing substantial ecological economic damage in forests. Understanding invasion pathways is essential tracking preventing these introductions. This study investigates two pine bark beetle species (<italic>Orthotomicus erosus</italic> <italic>Cyrtogenius luteus</italic>) South America using mitochondrial DNA analysis. We collected samples from native...
The occurrence of the exotic "granulate ambrosia beetle" Xylosandrus crassiusculus (Motschulsky) in Argentina and Uruguay is reported for first time, documenting expansion South America. Morphological characters are provided to allow distinction this species from other similar beetles. Molecular identification was also done on basis 5′ region mitochondrial cytochrome c oxidase I (COI) gene, obtained a specimen compared with available "barcode" sequences public databases. Phylogenetic...
Abstract Thaumastocoris peregrinus Carpintero & Dellapé (Heteroptera: Thaumastocoridae) is a sap‐sucking insect that feeds on leaves of Eucalyptus. In Uruguay, it was detected in 2008 causing significant economic losses Eucalyptus plantations. At present, there no efficient control for this pest; thus, the use biological agents seems to be an environmentally friendly alternative reduce damage caused by insect. The aims study were isolate and identify species entomopathogenic fungi...
Forestry in Uruguay has grown exponentially for the last 20 years. Even though plantations of Eucalyptus L’Her. account about 80% total forested area country, pine tree are relevant production high quality timber. Following introduction 1810, large scale started 1940, mainly with Pinus radiata Don (Pinaceae) (Porcile 2007). In 1950, seeds taeda L. and elliottii Engelm., among others, were brought from United States. To date, occupy 20% country (250,000 ha northern part country), mostly P....
Outbreaks of the southern pine beetle (SPB) Dendroctonus frontalis Zimmermann in Central America have had a devastating impact on forests. It remains unclear to what extent these outbreaks are caused by beetle’s ecology, climate, and historical management practices. Using research data experience accumulated northern latitudes guide forests is associated with great uncertainty, given many unique features conifer this region. The main recommendation from review that American bark need be...
We report the presence of invasive ambrosia beetle, Euwallacea fornicatus (Eichhoff, 1868), for first time in South America. The identity is established by morphological and molecular methods, although sequences suggest that it represents a separate haplotype from populations have caused significant damage Africa, Israel, California, most phylogenetically similar to specimens Asia greenhouses Europe. This pest one successful invaders, causing high economic ecological impacts regions where...
The increasing forested area in Uruguay facilitates the establishment of exotic bark and ambrosia beetles.In 2009, first infestation beetles was officially recorded.The outbreak included Hylurgus ligniperda, Cyrtogenius luteus Orthotomicus erosus.The objective this study to describe compare seasonal flight activity development time Pinus taeda commercial stands.Flight monitored by placing interception traps from July 2012 2013.Every 15 days, were collected.Development assessed with sets trap...
We present a reassessment of the diversity bark and ambrosia beetles in Cuba. For first time decades, an official Cuban-American binational collaboration allowed us to re-visit all known entomology collections Cuba, collect field. There are at least 94 species scolytine report new species, Xylosandrus aurinegro Gomez & Hulcr (Coleoptera: Curculionidae), 7 records, including genus record for Dryocoetoides Hopkins Tricolus Blandford (both Coleoptera: Curculionidae) island. In terms with...
Leptocybe invasa is a recently introduced forest pest, responsible for significant economic loss in Eucalyptus spp.plantations worldwide.The objective of this work to report its presence Uruguay, providing data distribution and biology.A survey galls was conducted from 2013 2015.The confirmed 15 out 35 surveyed points four 157 traps.Eucalyptus benthamii recorded as new host.Three periods emergence were observed.Life cycle completed only E. tereticornis, camaldulensis grandis.
