1 Dispersal of bark beetles and predators
Arnaud Costa and Dr John Reeve Insect Ecology Department of Zoology Southern Illinois University, Carbondale

2 1- Introduction: predators and bark beetles in the red pine system
Main objective: measure dispersal of three Coleoptera associated to red pine stands decline Predator: Thanasimus dubius (Cleridae) Root colonizer: Dendroctonus valens (Scolytidae) Bark beetle prey / Stem colonizer: Ips pini (Scolytidae)

3 Question: How far do these insects fly?
1- Introduction: predators and bark beetles in the red pine system Question: How far do these insects fly? - predators limit the expansion of declining stands by reducing Ips numbers - interactions could be approached by measuring dispersal of each guild member measuring beetles' dispersal evaluate connectedness among stands

4 2 - Methods - traps set at 50,100, 200, 300, 400, 500, 750, 1000, 1250, 1500, 1750 and 2000 m. Mark recapture grid

5 Semiochemicals / lures
2 - Methods Semiochemicals / lures Species Ipsdienol + lanierone Δ-3 carene frontalin α-pinene I. pini + + + D. valens “0” T. dubius

6 - insects will be released at the center of a grid of traps
2 - Methods Mark recapture - T. dubius and D. valens caught are marked with a spot of paint on the pronotum - I. pini will be marked with fluorescent powder while emerging from infested logs - insects will be released at the center of a grid of traps

7 3 - Field sites Mirror Lake Spring Green Kettle Moraine

8 Black rivers Falls ? (2006) Mirror Lake (2007) Spring Green
3 - Field sites Black rivers Falls ? (2006) Mirror Lake (2007) Spring Green Kettle Moraine (2006)

9 4 - Field sites Black rivers Falls (2006)

10 • Baiting traps early- mid April
4 – Expected schedule • Field sites hunting July March 2006 (“done”) - Kettle Moraine mid March (done) • Set grids of traps - Black rivers falls ? early April • Baiting traps early- mid April • Cut logs / Ips pini late April • 1st Capture/release (T. dubius / D. valens) mid May • 2nd Capture/release (T. dubius / D. valens) mid June • 1st Capture/release (Ips pini) mid June

11 T. dubius Recapture 2000 m 33 % caught > 2 km 66 %
(Cronin et al., 2000) 66 %
