1 Trapping Protocols 2008 Emerald Ash Borer Survey A. Trap Assembly (should be completed in the field) 1. Items needed: a. Traps (pre-glued) b. Cable ties - 7 inches long (2 per trap) c. Parchment or wax paper d. Utility knife 2. Two traps will come together with the glued faces touching. You should peel these apart. If you are only going to use one of the traps at a site, cover the exposed, sticky face of the other trap with the parchment (or wax) paper to protect it. Figure 1. Diagram of prism trap 3. The line (A) on the side containing the two slots should be scored with a utility knife (or similar item), taking care not to cut completely through the line. The two tabs (B) should be placed inside the slots (see picture below). Cable ties can be inserted into the holes marked (1) on Figure 1, and as shown below.

2 B. Low Trap Placement (on tree) 1. Items Needed: a. Assembled trap b. Cable ties - 7 inches long (4 per trap; 3 to attach the trap to the pole, 1 to attach the lure to the trap) c. Cable ties 4 feet long (2 per trap) d. Rebar pole ¼ inch diameter; 4 feet long with a 90-degree bend approximately in the middle, and a second slight (15-degree bend near the tip) 2. Attach the rebar pole to the tree by running two of the 4-foot cable ties around the diameter of the tree. One should be placed at the bend, and one at the bottom of the pole. 3. Seven-inch cable ties should be used to attach the traps to the pole the three positions marked (2) on Figure 1. The one at the bottom of the trap is not shown in the above photo, but the tie should be run around the pole, through the two holes, and then fastened. 4. The lure should be attached to the trap at hole (3) (Figure 1). Care should be taken to ensure the placement of the lure inside the trap, and not stuck to the glue on the outside. C. Low Trap Placement (off tree) 1. Items Needed:

a. Assembled trap b. Cable ties - 7 inches long (4 per trap; 3 to attach the trap to the pole, 1 to attach the lure to the trap) c.

5 feet down the pole so that the pole is L-shaped e. A rubber mallet or 5 pound sledge (may not be necessary) 2.

Place the trap over the top of the pole, so that the pole is inside the trap, and the top of the trap is flush with the top of the trap 3.

The lure should be attached to the trap at hole (3) (Figure 1).

3 a. Assembled trap b. Cable ties - 7 inches long (4 per trap; 3 to attach the trap to the pole, 1 to attach the lure to the trap) c. Cable ties 4 feet long (2 per trap) d. Rebar pole ¼ inch diameter; 8 feet long with a 90-degree bend approximately 1.5 feet down the pole so that the pole is L-shaped e. A rubber mallet or 5 pound sledge (may not be necessary) 2. Place the rebar pole in the ground, so that it stands upright. This may require the use of the mallet or sledge. 3. Place the trap over the top of the pole, so that the pole is inside the trap, and the top of the trap is flush with the top of the trap 3. Seven-inch cable ties should be used to attach the traps to the pole the three positions marked (2) on Figure The lure should be attached to the trap at hole (3) (Figure 1). Care should be taken to ensure the placement of the lure inside the trap, and not stuck to the glue on the outside. D. High Trap Placement (lower canopy). Pole Method 1. Items needed: a. Assembled trap b. Cable Ties 7 inches long (4 per trap; 3 to attach to spreader to the trap, and 1 to attach the lure to the trap) c. Spreader (may be different than in pictures below) d. Hanger

The spreader can be attached to the holes in the trap labeled (4) on Figure 1

The photos below illustrate this with the Umbrella Rig Spreader.

The hanger should then be attached to the spreader at the loop in the top, and

4 e. Pliers (or similar tool) f. Telescoping Pole (to 24 feet) with hanger attachment 2. The spreader can be attached to the holes in the trap labeled (4) on Figure 1 using the cable ties. The photos below illustrate this with the Umbrella Rig Spreader. Note: the design of the spreader may change. 3. The hanger should then be attached to the spreader at the loop in the top, and secured with the pliers. 4. The lure can be attached to the spreader on a loop located on the underside of the spreader. 5. Using the pole and attachment, the trap can be hoisted into the lower canopy, and the trap hanger placed over a (preferably large, stable) branch.

6. The trap can be taken down and serviced by

5 6. The trap can be taken down and serviced by slipping the attachment on the pole under the hanger, and lifting it off of the tree, and then down to the ground. E. High Trap Placement (lower canopy) Rope Method 1. Items needed: a. Assembled trap b. Cable Ties 7 inches long (4 per trap; 3 to attach to spreader to the trap, and 1 to attach the lure to the trap) c. Spreader (may be different than in pictures below) d. Hanger e. Pliers (or similar tool) f. Throw weight (14 or 16 oz) g. Throw line h. Rope (~ 100 ft per trap) i. Knife

Untie the throw line from the weight, and tie one end of the rope to that end of the throw line. Pull the throw line and rope back over the branch.

6 2. Follow the methods described in Section C (High Trap Placement (Pole Method)) for spreader attachment. 3. Toss the throw line, tied to the weight over a branch in the lower canopy. Allow, or coax the weight to fall to the ground. 4. Untie the throw line from the weight, and tie one end of the rope to that end of the throw line. Pull the throw line and rope back over the branch. When the rope is over the branch and reachable, untie it from the throw line, and tie it to the top loop on the trap. Tie a second section of rope to the bottom loop on the spreader (where the lure is attached). This second section will now be the steering rope, while the original section will be the pulling rope.

7 5. Pull the trap up to the branch using the pulling rope, while keeping it from banging against the tree with the steering rope. The steering rope can later be used to help pull the trap down when servicing it. Wrap the excess rope from both sections around the tree (preferably apart from each other).
