摘要：
In May 1989, a study was conducted in southwestern Idaho to test the hypothesis that infestations of Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, would not differ among plots containing five semiochemical baits per 0.4 ha, two semiochemical baits per 0.4 ha, and control plots containing no baits. On average, 5.8 times and 6.4 times more trees were infested on the plots with two- or five-bait treatments, respectively, compared with the control plots. The average number of infested trees did not differ significantly between baited plots. However, means in baited plots differed significantly from means in the control plots.
