松材线虫是一种非常细小的蠕虫,体长仅有14—16微米。可是,这个小虫却是世界各国严密防范的入侵生物,因为它就是松材线虫病的病原。松材线虫病又名松枯萎病,是影响最严重的森林病害,危害的对象主要是松属树种,如马尾松、黑松、白皮松和红松等,也包括部分非松属的树木,如一些落叶松属和云杉属的树种。患病的树木水分运输、光合作用、呼吸和蒸腾逐渐停顿,树皮变得干枯,针叶开始
Pine wood nematode is a very small worm, body length of only 14-16 microns. However, this bug is an invaded organism closely guarded all over the world because it is the causative agent of pine wilt disease. Bursaphelenchus xylophilus, also known as pine wilt, is the most seriously affected forest disease. The main targets are pine tree species such as Pinus massoniana, Pinus thunbergii, Pinus bungeana, Pinus koraiensis and Pinus koraiensis, as well as some non-Pinus species such as Some larch and spruce species. Sick trees water transport, photosynthesis, breathing and transpiration gradually pause, bark becomes dry, needles begin
