摘要
根据2009年林中不同位置引诱松褐天牛Monochamus alternatus Hope的试验结果,分析诱捕器周围林分因子对诱捕效果的影响,结果表明:郁闭度等5个林分因子对松褐天牛的诱捕量都有显著影响,其中,林分位置和郁闭度达到了极显著水平;在不同的林地植被覆盖率、坡向、坡位条件下,松褐天牛诱捕器的诱虫量都有显著差异。
This paper had analyzed the trapping effect based on the Monochamus alternatus quantity in different trap types in 2009. The results showed that the five forest stand factors around the traps have a significant impact to the trapping effect. Among them, the stand location and the shade densities reached extremely significant level. The traps in these places of different forest vegetation coverage rate, slope directions, slope positions, had significant differences.
