Cicadas Active in Virginia

In Virginia both the 17 and 13-year cicadas are active, and have drawn lots of notice from citizens. Cicadas are not poisonous and do not have a stinger, but the emerging cicadas create a substantial noise. The insects damage many ornamental and hardwood trees. Heavily infested areas reveal cicadas on just about any type of plant. Halifax and Hanover counties experienced heavy cicada activity.

Purple Prisms Pluck Pests

More than 5,500 purple prism traps have been placed to help detect the emerald ash borer.The large, purple triangle-shaped objects you may have seen hanging in a tree are part of the 2011 Emerald Ash Borer (EAB) survey. This year, the survey has expanded significantly. More than 5,500 traps have been deployed statewide. With one trap placed per 2x2 mile grid area, you’ll probably see one soon.

The traps are especially useful for revealing new infestations that would otherwise remain undetected. This year, a large swath of central, southern and western Virginia forms the trapping grid. The 14" wide by 24" long traps are baited with natural plant oil attractant and covered with a non-toxic glue to catch the insects.

The EAB larvae kill ash trees by feeding on the inner bark and disrupting the tree’s ability to transport water and nutrients. EAB was introduced accidentally into the United States and was first detected in Michigan in 2002. The first EAB detection in Virginia occurred in Fairfax County in 2003. Subsequent detections at multiple sites in 2008 resulted in the establishment of a quarantine for more than 10 northern Virginia counties and independent cities. The quarantine is an effort to slow the spread of this destructive beetle by restricting the movement of articles capable of transporting EAB.
