Fungal Biology Available online 25 February 2021 Fungi associated with galleries of the emerald ash borer. The emerald ash borer (EAB) is an exotic forest pest that has killed millions of ash trees in the United States and Canada, resulting in an ecological disaster and billions of dollars in economic losses of urban landscape and forest trees.

Fungal Biology Available online 25 February 2021 Fungi associated with galleries of the emerald ash borer

The beetle was first detected in Michigan in 2002 and has spread through much of the Eastern and Midwestern U.S., reaching Minnesota in 2009. Since then, it has spread across the state and poses a great risk to the more than 1 billion ash trees in Minnesota. The larval stage of EAB creates wounds on trees as they feed on the inner bark, causing disruption of water and sap flow that results in tree death. The fungal community associated with EAB larval galleries is poorly understood and the role these fungi may play in tree death is not known. This study describes fungi isolated from EAB larval galleries sampled throughout the main geographic areas of Minnesota where ash is affected by EAB.

SILIVE 03/06/20 NYC releasing stingless wasps to combat tree-eating beetle (agrile du frêne) STATEN ISLAND, N.Y. -- In an effort to combat a beetle endangering a species of tree found throughout New York City, the city Parks Department is releasing parasitoid (or stingless) wasps in Willowbrook Park.

SILIVE 03/06/20 NYC releasing stingless wasps to combat tree-eating beetle (agrile du frêne)

Ash trees, a common native tree species in this area, are being eaten by insects known as emerald ash borers. The insect was first identified in New York City in October 2017. And for the first time ever, the New York City Department of Parks and Recreation is releasing the wasps as a form of biocontrol -- which is the reduction of pests through the use of natural enemies -- against the invasive insects. The wasps only attack the emerald ash borers, the agency said. The use of parasitoid wasps is approved by the U.S. According to the Parks Department, New York State has already introduced these wasps in other areas to control the spread of emerald ash borers -- but this is the first time the wasps are being released in New York City.

Elle est toutefois très efficace dans la lutte contre l’agrile. Les guêpes pondent leurs oeufs directement dans les larves de l’agrile du frêne, situées à la surface de l’écorce des frênes. Lorsque les oeufs des guêpes éclosent, les jeunes guêpes se nourrissent des oeufs ou des larves de leur hôte, explique l’Agence canadienne d’inspection des aliments. Selon un chercheur du Service canadien des forêts, Chris McQuarrie, de 500 à 1000 de ces mini guêpes seront libérées dans la région d’Edmundston cet été. Il faudra quatre ans avant que l’on sache si les guêpes ont réussi à s’établir durablement dans les forêts de la région. Des résultats prometteurs au Michigan M. Les guêpes ont ensuite été introduites au Québec et en Ontario, à partir de 2013. Un insecte redoutable.

Ces guêpes, originaires d'Asie, tout comme l'agrile, sont des prédateurs naturels du coléoptère indésirable. De la taille d'une tête d'aiguille, elles sont inoffensives pour l'humain, précise-t-on. Quelque 3000 femelles de cette espèce seront relâchées au cours de la saison estivale, au Bois-de-Coulonge, mais aussi sur les plaines d'Abraham, lieux connus pour la présence de l'agrile dans la capitale. Tête chercheuse Les guêpes ont été insérées dans des bûchettes, lesquelles contenaient des larves d'agriles. Tels des missiles à tête chercheuse, elles ont la capacité de détecter leur cible sous l'écorce.

FORESTS 15/03/18 Progress and Challenges of Protecting North American Ash Trees from the Emerald Ash Borer Using Biological Control

This biocontrol program began in 2007 after federal regulatory agencies and the state of Michigan approved release of three EAB parasitoid species from China: Tetrastichus planipennisi Yang (Eulophidae), Spathius agrili Yang (Braconidae), and Oobius agrili Zhang and Huang (Encyrtidae). A fourth EAB parasitoid, Spathius galinae Belokobylskij (Braconidae) from Russia, was approved for release in 2015. We review the rationale and ecological premises of the EAB biocontrol program, and then report on progress in North American ash recovery in southern Michigan, where the parasitoids were first released.

A sample of 1000 contigs harbored 150–550 k SNPs or 1–2.8 SNPs per kb. A phylogeny base on these SNPs clarified relationships among the 4 species. Four primer pairs amplified fragments with fixed length differences between species.

VILLE DE MONTREAL - Lutte biologique - Agrile du frêne. L’agrile du frêne menace actuellement la forêt urbaine. En Amérique du Nord, l'éradication de cet insecte ravageur est impossible. Les experts recommandent plutôt la mise en place de la lutte biologique partout où cela est possible et réalisable. Dans ce contexte, la lutte biologique classique, par l’utilisation d’ennemis naturels exotiques de l’agrile, s’avère une stratégie à long terme pour la sauvegarde des boisés naturels en milieu urbain. Projet d’envergure à Montréal Ce projet consiste à relâcher des ennemis naturels de l’agrile, des guêpes parasitoïdes de l’espèce Tetrastichus planipennisi (Photo : David Cappaert, Michigan State University, Bugwood.org) et de l'espèce Oobius agrili dans certains boisés de l'île de Montréal.

Comment ça fonctionne? En combinant les deux espèces de parasitoïdes, on attaque ce ravageur sur deux fronts. Forest Health Technology Enterprise Team - 2014 - Emerald Ash Borer Biological Control. USDA FOREST SERVICE 06/05/16 Biological Control of the Emerald Ash Borer. Research Issue In 2002, the emerald ash borer (EAB), Agrilus planipennis(Coleoptera: Buprestidae), an Asian beetle that feeds on ash trees (Fraxinus spp.), was discovered as the cause of widespread ash tree mortality in southeastern Michigan and nearby Windsor, Ontario.

Evidence shows that EAB was introduced to Michigan during the early 1990s by transport of infested solid-wood packing materials from China. Despite eradication efforts by regulatory agencies in the U.S. and Canada, EAB is now considered established throughout much of Michigan and areas of Illinois Indiana, Ohio, Pennsylvania, and Ontario, Canada.
