This study investigates the effects of semiochemical treatments on the catch of Dendroctonus simplex in funnel traps over a period from 2001 to 2003. It compares data collected in diverse land areas, including undisturbed, wind-disturbed, salvaged, and burned regions. Results show variations in the number of D. simplex captured, revealing insights into the effectiveness of different semiochemical treatments in managing this pest across distinct ecological conditions.
