This indicated that the resin excreting speed of pines was negatively correlated with disease resistance to Bursaphelenchus xylophilus. 因此，樹榦泌脂速度或樹脂含量可能是評價松樹對松材線蟲病抗性的重要性狀之一。
Besides, the trace observations on the amount of B. xylophilus into pine twigs revealed that the peak period of nematode transmission advanced in higher temperatures. 通過對松褐天牛取食傳入松枝的松材線蟲量的追蹤記錄發現，隨著溫度的升高，傳播線蟲的高峰時段隨之提前。
