PhD student or a Postdoc position: Invasive wood borers

Join the Forest Entomology team (http://www.ambrosiasymbiosis.org/) at the University of Florida on our quest to discover which of the thousands of wood borer species in exotic jungles have the potential to be the next big invader into American forests. We are looking for passion in areas ranging from molecular ecology to integrative taxonomy to biosecurity regulation, someone who can master the flow of material from a foreign jungle to a DNA sequencer, someone who will love analyzing their data, writing their manuscripts, and strategically posting on social media.

Georgia’s pecan producers need to scout for pests like the Asian ambrosia beetle

by Clint Thompson, University of Georgia

Pecan season may be over, but Georgia’s producers should continue to scout for pests, like the Asian ambrosia beetle, that could impact future crops.

A New Invasive Insect and Disease Threatens the Avocado Industry

While on vacation in Hilton Head, South Carolina in August 2004, Minnesota plant pathologist Kathy Kromroy hiked through the Newhall Audubon Nature Preserve. As she walked, she noticed several trees drooping with wilted leaves. A park display blamed the death of the trees on a long drought, but Kathy noticed that only one tree species was dying. All of the other trees were still green and thriving.
