Sirex Trapping Survey Update

Well, we wrapped up our trap construction and initial collections for Sirex spp. in white pine stands.  And we finally caught some wasps!

Urocerus cressoni collected from one of our Cold Mountain traps.

Sirex nigricornus collectedfrom one of our Dupont S.F. traps.

We made our final collections from funnel traps during the last week of October.  The traps attracted everything from bark beetles to grasshoppers to woodwasps, but it was the bears that made the most significant impact.

Teeth marks most likely from a bear snooping around our traps.

 Evidence of a large mammal disturbing a trap at Cold Mountain.

Our lincoln log stacks will remain in the forest until summer.  We will retrieve them and rear out whatever critters have decided to colonize the trap.
