| 摘 要： | 松褐天牛从取食开始到试验结束（50d），将松材线虫通过补充营养伤口传递到健康松树，取食到20d时传递的数量最多，每头694条，到第30天数量较多，在此之前和之后数量较少，每头100条左右。松褐天牛将60％的松材线虫传递到当年生树树，随着树枝年龄增加，传递数量减少。实验室和林间试验分离分离测计表明，松褐天牛的身体仍残留一定数量的松材线虫。

| Abstract: | Transmission characteristic of pinewood nematode, Bursaphelenchus xylophilus through feeding wounds of Monochamus alternatus was investigated from feeding beginning to experiment end for 50 days.The result showed that the number of nematode transmitted to pine trees was greatest about 694 nematode per sawyer at the 20th day,and was greater at the 30th day after feeding but about 100 nematode per sawyer was transmitted at before and after these day.60% of nematode was transmitted to one year old pine branches,but the number of nematode was less with increase of pine branch age.The laboratory and forest field test showed that a few number of nematode remained within the sawyer,thus it was provided one of basis for early detecting the pine wilt disease. |
