杉木半穿刺线虫新发现三种寄主植物杉木、柳杉、野柿，原国内外报道寄主植物有柑桔、甜橙、橄榄、葡萄、紫丁香、核桃、杏树、海棠、苹果、梨、柿树、构桔、黄杨、桂花、兰棕等．杉木与非杉木半穿刺线虫寄主植物马尾松、酸枣、泡桐、火力楠、湿地松、楠木、檫树、油桐、枣柏、木荷等混交，可大大降低虫口密度，促进杉木生长，是一种较好的控制线虫密度的营林措施；杉木与杉木半穿刺线虫寄主植物柳杉混交，其虫口密度大大增加 Chinese cedar (Nelumbo nucifera) has newly discovered three kinds of host plants: cedar, cedar and wild persimmon. The host plants of citrus, orange, olive, grape, lilac, walnut, apricot, Tree, structure orange, boxwood, sweet-scented osmanthus, blue-brown and so on. Chinese fir and non-Chinese fir semi-pierced nematode host plants Masson pine, jujube, Paulownia, pyracantha, Slash pine, Phoebe bournei, tung tree, jujube, Schima superba, etc. can greatly reduce the population density and promote the growth of Chinese fir, is a Better control of nematode density silviculture measures; fir and Chinese fir semi-pierced nematode host Cryptomeria mix, the population density increased greatly
