通过两种指示剂对不同类型疫区、非疫区病、健木以及不同试样类型的测试表明：０．０４％溴酚兰酒精溶液对松材线虫病（Ｂｕｒｓａｐｈｅｌｅｎｃｈｕｓｘｙｌｏｐｈｉｌｕｓ）的检疫检验，准确率可达８５％以上；０．０４％二甲基黄酒精溶液（ｐＨ＝２）只达６０％，效果较差。检验时所取试样，无论是木段的横断面还是木屑均可。此外，两种指示剂均不能区分松材线虫病死木和有松天牛（Ｍｏｎｏｃｈａｍｕｓａｌｔｅｒｎａｔｕｓ）、拟松材线虫（Ｂ．ｍｕｃｒｏｎａｔｕｓ）分布的病死木。利用指示剂进行松材线虫病快速检验已获初步成效，但推广应用尚待深入研究
The tests of different types of epidemic area, pest free area disease, healthy wood and different sample types by two kinds of indicator showed that the detection rate of Bursaphelenchus xylophilus with 0.04% bromophenol blue in alcohol solution was higher than that of Bursaphelenchus xylophilus Up to 85%; 0.04% dimethyl yellow alcohol solution (pH = 2) only up to 60%, the effect is poor. The test sample taken, whether wood cross-section or wood chips can be. In addition, neither indicator could distinguish between dead wood from pine wilt disease and dead wood from Monochamusalternatus and B. mucronatus distribution. Rapid detection of pine wood nematode using indicator has achieved initial success, but the application has yet to be further studied
