Asian longhorned beetle outbreak reported on Long Island

By Curt Kipp — Posted October 2, 2014

Officials are redoubling their efforts to stamp out the Asian longhorned beetle in New York City and Long Island, according to a report in the New York Times.

Website educates public on invasive pest threats

By Curt Kipp — Posted April 3, 2014

Although the agriculture community is well aware of invasive pests and pathogens — including the emerald ash borer, sudden oak death, the giant African snail, the citrus psyllid, the Asian longhorned beetle and many others — agriculture cannot fight them alone. These pests can be transported unwittingly by the general public; therefore, public awareness is needed to […]

Oregon gets a B- in invasive species management

By Curt Kipp — Posted January 15, 2014

Oregon, as a whole, could be doing better in its fight against invasive species. That’s the verdict from the Oregon Invasive Species Council (OISC), which gave the state a B-minus on its annual Invasive Species Report Card (PDF). That’s down a full letter grade from 2012, when the state received an A-minus. The main difference? […]

Azalea lace bug (Stephanitis pyrioides) There is a relatively new pest in Oregon that can damage azaleas, rhododendrons and pieris (Ericaceae): The azalea lace bug (Stephanitis pyrioides) was first confirmed in Oregon in 2009 by Oregon State University (OSU) researchers after it was found in Washington in 2008.

Oregon gets an A minus on invasive species report card

By Curt Kipp — Posted January 15, 2013

Minnesota enlists dogs against emerald ash borer

Asian longhorned beetle traps developed

By Curt Kipp — Posted March 14, 2012

Researchers have developed a trap (PDF) for luring in the destructive and much-feared asian longhorned beetle (ALB), which has no natural enemies as it cuts a path through neighborhoods and forests. The secret? Bug pheromones. Hat tip to “bug ladies” Suzanne Wainwright-Evans and Robin Rosetta for passing this information along.

An enemy for the emerald ash borer

By Curt Kipp — Posted December 14, 2010

We don’t have the emerald ash borer in Oregon, and we hopefully never will. But this blog post talks about a new way of detecting fighting the tree-killing beetle — predatory wasps. Evidently the wasps will quickly find the beetle if it is present in the area. This definitely beats the method of watching for […]
