Comparison on Efficiency of Pheromone Lures Equipped with Panel Traps in Catching Japanese Pine Sawyer Monochamus alternatus Adults

Objective To screen effective pheromone lures.

Method A field test was carried out to investigate the attractiveness to Monochamus alternatus of 2 new pheromone lures (lure A and lure C) in compare with lure B and lure D.

Result The results showed that lure A could catch more M. alternatus beetles than the other lures, which were 1.17, 1.41 and 1.58 times as many as that of lure B, lure C and lure D respectively. The trapping amount of lure C was higher than that of lure D, but no significant difference was found between them. The average amount of female beetles attracted by the pheromone lures were 1.76 times as many as that of male ones.

Conclusion Lure A, with higher efficiency, stability and persistence, is more effective and reliable than the other 3 lures. So the priority should be given to lure A in monitoring and controlling M. alternatus adults.
