Survey using pheromone traps, of Gnathotrichus sulcatus (Col: Scolytidae) in two Vancouver Island dryland sorting areas

J. A. McLean

Abstract


Forty-eight traps baited with the aggregation pheromone, sulcatol, were placed in two dryland sorting areas on Vancouver Island, B.C. during 1977. A late-summer peak flight of the ambrosia beetle <i>Gnathotrichus sulcatus</i>, was recorded in both areas. Trap sites with the greatest catches of <i>G. sulcatus</i> showed where suppression traps would be most effective.
