Insecticides should be used only where treatment is deemed necessary for the tree's health. Methods to Improve Survival and Growth of Planted Alternative Species Seedlings in Black Ash Ecosystems Threatened by Emerald Ash Borer. The Emerald Ash Borer (EAB) is a small, invasive beetle that is devastating to all ash tree species in MA. 73 species of insects that rely on ash trees are being threatened with extinction, as their habitats are being destroyed. All biocontrol species are thoroughly researched prior to introduction into the ecosystem to avoid any negative impacts. the City. For emerald ash borer life stages found in ash saplings, we constructed lifetables and estimated population growth rates using methods previously applied in larger ash trees at the same sites from 2008 to 2014 (Duan et al., 2014, Duan et al., 2015). Influence spread of EAB populations. MERCADER ET AL. The invasion spread of the emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Buprestidae) is characterized by the formation of satellite populations that expand and coalesce with the continuously invading population front. A tree in Lafayette, Colo. damaged by the emerald ash borer. May be used as detection tools and management tools to reduce population growth. In predetermined locations, the bureau has treated 1,700 ash trees within the state forest system for emerald ash borer between the years 2014-2015. Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. BROOMFIELD, Colo. – National and state experts have confirmed the presence of emerald ash borer (EAB) – an invasive, highly destructive tree pest – in the City and County of Broomfield, northwest of Denver. since it was accidentally introduced to North America in the 1990s. emerald ash borer populations would be expected to rebound to current densities in a generation or less (<1 to 2 years); however, this brief population setback provides additional time for communities to develop or implement plans for ash borer management. (2011) SIMULATING THE EFFECTIVENESS OF THREE POTENTIAL MANAGEMENT OPTIONS TO SLOW THE SPREAD OF EMERALD ASH BORER (AGRILUS 2.2. The emerald ash borer has killed approximately 200 million of the United States’ 8 billion ash trees since their discovery in the US. Birds such as woodpeckers feed on emerald ash borer larva, although the adult beetles have not been used by any American fauna as food. (2003) and Bauer et al. Understanding how predators such as woodpeckers (Picidae) affect the population dynamics of EAB should enable us to more effectively manage the spread of this beetle, and toward this end we … Ash trees that have a historic or ecological significance as well as select seed producing ash trees are currently being treated with a systemic insecticide to prevent attack by EAB.
