    Notes: Abstract The bark beetles,Ips pini andI. paraconfusus, are not cross-attractive in the field although they attack the same host material at the same time. Logs containing the pheromone-producing sex (males) of both species side by side attract significantly fewer beetles of each species than do males of either species alone. Ipsenol, a component of the maleI. paraconfusus pheromone, duplicates the activity of maleI. paraconfusus in inhibiting the response ofI. pini to maleI. pini. Linalool from maleI. pini also reduces the catch ofI. paraconfusus in response to maleI. paraconfusus. Simultaneous production of a specific attractant pheromone and an interspecific chemical inhibitor favors exclusive use of the host substrate by the first arriving species.
