The Asian longhorned Beetle A pest we can stop through early detection Joanna Fisher Department of Entomology Cornell University [email protected] What is the Asian longhorned beetle? J. Fisher Bugwood.org Bugwood.org Bugwood.org Before ALB Bugwood.org After ALB 19,344 trees destroyed: New York 6,963 infested! 34,329 trees destroyed: Massachusetts 24,213 infested! 61,756 trees destroyed: Bethel Ohio 6,963 infested! Monitoring by the public is critical! Before ALB “The public is our first line of defense because early detection is crucial and could mean more trees saved”- Rebecca Blue, Deputy Under Secretary of the USDA (APHIS). After ALB Bugwood.org Early detection is critical! All but one unique outbreak first detected by homeowners Worchester is the largest infestation: Went undetected of about 10 years Willow, Salix Buckeye, Aesculus Ash Maples, Acer ALB has a very wide host range! 47 Deciduous tree species, from 14 plant families Sycamore, Plantanus Bugwood.org Birch, Betula horsechestnut, Aesculus © Bugguide Forestry Imates Elm, Ulmus According to 2001 estimates, it would cost the US $669 billion to remove and replace vulnerable trees ($2.2 billion NY) Bugwood.org Reductions of tree canopy up to 35% Up to 30% tree mortality Bugwood.org Questions/ Comments?
