Welcome to the Delaware Invasive Species Council
New Pest Alert:
Japanese Cedar Longhorned Beetle
There's a new pest on the watch list called Japanese cedar longhorned beetle. It has been found in Newark and may be present in other areas. No one really knows for sure since no surveys have been done.
It has been confirmed in other states on Leyland-cypress, arborvitae, and eastern redcedar. If you find groups of declining trees of these species, look for exit holes, frass, and larval damage. Exit holes are oval-shaped and small (about an eighth of an inch).
This is a reportable pest for APHIS. If you think you may have found it please contact Jimmy Kroon in Plant Industries on this (302) 698-4500.

Be Alert:
Kudzu and the Kudzu Bug
The kudzu bug, that was first detected in the United States in November of 2009. It was first identified on kudzu in Georgia. Unlike stink bugs which tend to feed on soybean pods and beans, it prefers to feed on soybean petioles and stems, removing plant sap which can ultimately results in significant yield losses. In Georgia, yield losses as high as 20 BU/A have been documented. Since being identified, it has rapidly spread throughout Georgia and been identified in South Carolina, North Carolina, Tennessee, and Virginia ( in one county near the North Carolina border).
All indications suggest that it will continue to spread at a rapid rate and potentially reach Delaware in 2012. It appears, although it is not totally confirmed, that it starts in kudzu but then moves to soybeans. So far the only two plants that it is known to complete its life cycle on are kudzu and soybeans. We are interested in finding a mix of kudzu locations - some near soybeans as well as isolated patches - to use as survey sites.

The DISC Education/Outreach Committee has submitted a workshop proposal to the Delaware Teacher Center.
Delaware's MOST WANTED: Understanding the First State's Nastiest Invasive Species
Blackbird Creek Reserve, Townsend, DE Tuesday, August 14, 2012
Teachers will participate in content presentations and hands-on activities, from state natural resource educators, focusing on the top terrestrial and aquatic invasive species of Delaware and the region. Once teachers are fully briefed on invasives, they will participate in an invasives-removal exercise at the workshop site. Teachers will receive a wealth of classroom resources and other materials, which will be aligned to state standards where possible.
At the end of the invasive species workshop, participants will be able to:
- Define the term invasives species
- List at least five vectors of invasive species
- Identify at least five of Delaware’s terrestrial and aquatic invasive species
- Introduce their students to Delaware’s “Most Wanted” invasive species
- Plan an invasive species removal project

About DISC
An invasive species is an alien species whose introduction causes or is likely to cause economic or environmental harm or harm to human health according to the National Invasive Species Monitoring Plan. The spread of invasive species is a pervasive and growing problem within Delaware and the United States.
The Delaware Invasive Species Council, Inc. (DISC) was formed to help Delaware deal with this rapidly growing problem.
