Management Tactics for Ambrosia Beetles Attacking Horticultural Tree Crops
Wednesday, May 10, 2 p.m. EST 
Christopher M. Ranger, Ph.D. | Research Entomologist, Horticultural Insects Research Lab — USDA-Agricultural Research Service

If you've already experienced or are at risk for exotic ambrosia beetle attacks, this webinar is critically important for management strategies and prevention measures that will ultimately impact your bottom line for better or for worse.

Exotic ambrosia beetles are among the most destructive pests of trees growing in ornamental nurseries and tree fruit orchards. Beetles tunnel deep into the heartwood of trees, where they farm and consume their fungal symbiont. Pathogenic microorganisms can also be passively introduced into host trees during tunneling and gallery formation. Symptoms resulting from attacks include toothpicks protruding from the tunnel entrance, defensive sap production, wilting, and branch dieback. A wide range of trees are attacked, but thin-barked deciduous trees are generally preferred. Host quality plays an important role during host selection and beetles efficiently locate and preferentially attack physiologically stressed trees that are emitting ethanol. A variety of stressors can induce ethanol; flooding/inadequate drainage, frost injury, and freezing injury have preceded extensive attacks on intolerant trees growing in ornamental nurseries and tree fruit orchards. Monitoring and management tactics will be discussed for these destructive pests.
