Adult beetles average 3/8″ to 3/4″ long and 1/6″ wide. For best results, the insecticide should be injected prior to infestation, or as soon after infestation as possible, and during adult EAB emergence in the late spring or early summer (OMAFRA, 2013), A technician injects an infested ash tree with insecticide to control emerald ash borer. 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). Native to China, Mongolia, North Korea, South Korea, Japan, Taiwan, and the Russian Far East, the emerald ash borer beetle (EAB) was unknown in North America until its discovery in southeast Michigan in 2002. Typical signs of EAB infestation include crown dieback and epicormic branches. 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). Violating these restrictions could result in fines and/or prosecution (CFIA, 2014) . There are two main methods of detection used for emerald ash borer: 1. Even if a tree is injected with the insecticide, it may take several years to fully recover from the EAB infestation, and re-treatment may be needed to prevent additional infestations.

Branch sampling allows for detection of the pest even at low population densities. There are several control methods currently being used to contain EAB to infested sites within Southern Ontario: MechanicalEAB infested trees can be cut down and their wood either burned or buried. Experts believe the EAB was introduced to Detroit hidden inside wooden packaging materials or shipping crates. The plan includes the removal of specific ash trees and chemical treatment of specimen trees. Experts believe the EAB was introduced to Detroit hidden inside wooden packaging materials or shipping crates. The full story is even darker. The Invasive Species Centre aims to connect stakeholders. The emerald ash borer beetle is considered one of the most serious invasive species in Maine, according to the Maine Department of Agriculture, Conservation and Forestry. Urban tree removal comes at a high economic and ecological cost for municipalities across infested areas. These parasitoids are being used in an attempt to control the spread of EAB and to reduce its population. In 2015, it was found in many additional counties. Three species have been released in Canada (Tetrastichus planipennisi, Spathius galinae, and Oobius agrili), the fourth species (Spathius agrili) has not been released as research has shown it would not be able to successfully establish a population in a Canadian climate.
