This polyphagous insect is not known to occur in Canada and poses a significant threat to Canada's forests, biodiversity and economy. The larval stages (i.e. caterpillars) (Figure 2) feed on the leaves of many economically important trees such as oak, larch, birch, alder, hazelnut, apple, cherry, pear, poplar, willow, pine and spruce. Caterpillars can consume the entire leaf and under high populations, this insect can strip all the leaves from a tree leading to reduced growth and in the event of multiple years of defoliation, tree mortality. <o:p></o:p></p><p class=MsoNormal>Female moths lay egg masses (Figure 3, 4) on host trees as well as man-made structures. This behavior allows this moth to hitch-hike to new areas – thus the term gypsy moth.<o:p></o:p></p><h2><span lang=EN-US>Pathways into Canada<o:p></o:p></span></h2><p class=MsoNormal>As with many moths that are nocturnal, female AGM are attracted and fly towards lights. When containerized consignments (e.g. iPads, running shoes, granite, food, etc.) are loaded onto ships and cargos in Asia, female moths can lay egg masses on them or their content. If the egg masses arrive in Canada during the hatching period, the larvae will disperse with the wind over long distances, thereby increasing the likelihood of finding a host tree. If enough individuals successfully develop to the moth stage, a population could become established.<o:p></o:p></p><h2><span lang=EN-US>What Can You Do To Help?<o:p></o:p></span></h2><p class=MsoNormal>As AGM feeds on a wide range of hardwood and coniferous trees, its introduction into Canada would likely impact municipal street trees and natural areas as well as many industries. Therefore, early detection of this pest, if introduced into Canada is crucial. This is why the Canadian Food Inspection Agency has put in place a <a href="http://www.inspection.gc.ca/plants/plant-protection/plant-pest-surveillance/eng/1344466499681/1344466638872">surveillance program and developed outreach tools</a> for this pest.<o:p></o:p></p><p class=MsoNormal>If you see suspect egg masses or adult moths, please contact your local CFIA<a href="http://www.inspection.gc.ca/about-the-cfia/offices/eng/1313255382836/1313256130232"><span style='color:windowtext;text-decoration:none'> o</span>ffice</a>. AGM is regulated by the CFIA.

Cet insecte polyphage (qui s’accommode de nourritures variées) n’est pas un insecte indigène au Canada et il pose un grand risque aux forêts, à la biodiversité et à l’économie du Canada. Au stade larvaire (p. ex. chenille) (Figure 2), cet insecte se nourrit des feuilles d’arbres ayant une importance économique, comme le chêne, le mélèze, le bouleau, l’aulne, le noisetier, le pommier, le cerisier, le poirier, le peuplier, le saule, le pin et l’épinette. Les chenilles peuvent consommer la feuille au complet et lorsque leur population est élevée, ces insectes peuvent enlever toutes les feuilles d’un arbre, entravant sa croissance et, lorsque l’arbre subit plusieurs années de défoliation, causant sa mort.<o:p></o:p></span></p><p class=MsoNormal><span lang=FR-CA>Les spongieuses femelles pondent des grappes d’œufs (Figures 3 et 4) sur les arbres infestés ainsi que sur des structures artificielles. Ce comportement permet aux spongieuses de se déplacer d’un endroit à l’autre.<o:p></o:p></span></p><h2><span lang=FR-CA>Voies d’accès au Canada<o:p></o:p></span></h2><p class=MsoNormal><span lang=FR-CA>Comme c’est le cas de différents papillons de nuit, les spongieuses asiatiques femelles sont attirées et se dirigent vers la lumière. Lorsque de la marchandise transportée par conteneur (comme des iPads, des espadrilles, du granit, de la nourriture, etc.) est chargée dans des cargaisons et sur des navires en Asie, les spongieuses femelles peuvent pondre des grappes d’œufs sur les conteneurs ou la marchandise. Si les grappes d’œufs arrivent au Canada pendant la période d’éclosion, les larves se disperseront au vent sur de grandes distances, leur donnant ainsi plus de chance de trouver des arbres hôtes. Si un nombre suffisant de larves atteignent le stade adulte, une population peut s’établir.<o:p></o:p></span></p><h2><span lang=FR-CA>Que pouvez-vous faire pour aider à prévenir les infestations?<o:p></o:p></span></h2><p class=MsoNormal><span lang=FR-CA>Comme la spongieuse asiatique peut consommer diverses espèces de feuillus et de conifères, son introduction au Canada aurait probablement des répercussions sur les arbres de rue municipaux et les aires naturelles ainsi que sur plusieurs industries. Il est donc essentiel de déceler sa présence dès le début si cet insecte s’introduit au Canada.
