3.3. Monitoring data
A monthly overview of each facility revealed two different patterns of growth for detected beetle population levels (Fig. 2). Average daily trap capture rates observed for the first month after fumigation (September) in Facility B were five times the rates observed in the first month after fumigation (August) for Facility A. Additionally, Facility A population levels exhibited an almost steady, incremental growth pattern across all months of the observation period, while Facility B exhibited an irregular growth pattern that grew and fell from one month to the next.
