| 摘 要： | 通过对病根中媒介昆虫松褐天牛种群数量、松材线虫密度以及线虫演替规律的调查研究,对伐根在松材线虫病流行中的作用进行初步评价。认为伐根在病害流行中的作用很小,考虑到挖除病根增加的劳动强度和经费支出,今后在疫区内部可以不强调挖根,而在疫区的边缘应挖除病根以防止这种国内森林植物检疫对象的自然蔓延。

| Abstract: | In order to evaluate the effect of stumps on epidemic of pine wilt disease caused by pine wood nematode (PWN), Bursaphelenchus xylophilus, the pine stumps of pine wilt disease were surveyed and the population density of PWN and its vector, Monchamus aiternatus and succession of the nematodes were studied in pine stumps. It is considered that the effect of stum ps on epidemic of pine wilt disease is not important. Considering of increase of labor intensity and payment to uproot stumps, it is suggested that the uprooting of stumps is not necessary in the disease control in the central areas of occuring Bursaphelenchus xylophilus. And the stumps should be uprooted to provent the disease from natural spread in the border areas of occuring pine wilt disease. |
