The emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), was discovered as the cause of extensive ash tree (Fraxinus spp.) An interactive story map of the USDA’s history of combating the infestation and the continuing efforts to protect ash trees in the U.S. ChemicalIn Canada, chemical control of EAB is undertaken using a systemic insecticide with one of three active ingredients (imidacloprid, acephate, and azadirachtin) which is directly injected into the trunk of a recently infested tree, or a tree that is susceptible to infestation (NRCan, 2013). In an attempt to control the spread of EAB in Canada, the Canadian Food Inspection Agency (CFIA) has developed regulations that restrict the transport of ash materials (such as firewood) out of affected areas, under the Plant Protection Act (CFIA, 2011). Larvae: 25 – 32 mm long at maturity, creamy white in colour, brown head, flat, broad shaped body; 10-segmented abdomen (bell-shaped segments) and a fork-like appendage on the tip of the abdomen.

The emerald ash borer (EAB) is an invasive wood-boring beetle, native to parts of Asia. Some potential ecological impacts are as follows: changes to forest structure, altered canopy gaps, reduced coarse woody debris, altered biogeochemical and nutrient cycling, and altered ecological interactions among organisms (both aquatic and terrestrial). In 2013, the emerald ash borer was found in Granville, Person, Vance, and Warren counties in North Carolina. You may also see larval galleries (pictured below, right) beneath the bark. Several tiny wasp species are helping to control EAB. Map: U.S. Department of Agriculture (June 2018).https://www.aphis.usda.gov/plant_health/plant_pest_info/emerald_ash_b/downloads/AshRangeMap.pdf.

Since its arrival, the EAB has been rapidly spreading across North America, having devastating effects on the ash tree population, killing up to 99% of ash trees in its path. Emerald ash borer can only fly within a 15 km radius. EAB is responsible for the death of millions of ash trees in the Midwest. Management efforts no longer focus on eradication of the insect from Canada, as this is not a realistic outcome. First confirmed sighting of a new invasive in North America: elm zigzag sawfly, Epicormic branches (shoots that typically grow out of the lower trunk, but can be found on all parts of the trunk or branches). Although the direct effects of EAB on ash trees are fairly conspicuous, the indirect or downstream ecological impacts of EAB are much more difficult to quantify. EAB emerges in late spring, flying from June to August. A new USDA Forest Service study shows that e-noses can detect emerald ash borer (Agrilus planipennis) larvae lurking under the bark – an early, noninvasive detection method. These insects could make their way into Montana through firewood brought from out of state. 1. As of February 2014, all 99 counties in Iowa have been quarantined (.

USDA. The Invasive Species Centre aims to connect stakeholders. Prevention of an emerald ash borer infestation in a new area is the most effective way to reduce long-term impacts. 2. In Ontario, EAB has become well established and its distribution continues to increase from natural spread of the insect flying from tree to tree and from human-mediated spread through movement of infested ash materials.
