The host range of the knapweed nematode, Subanguina picridis (Kirjanova) Brzeski, under controlled environmental conditions was extended to include, in addition to Russian knapweed, Acroptilon repens (L.) DC., plant species within the Centaureinae, and Carduinae subtribes of the Cynareae tribe of the Asteraceae family. Examination of host response to nematode infection revealed that Russian knapweed was the only highly susceptible host plant. Diffuse knapweed (Centaurea diffusa Lam.) was moderately susceptible, and other plants which formed galls were resistant to S. picridis.
在可控环境条件下，矢车菊线虫（Subanguina picridis (Kirjanova) Brzeski）的寄主范围得以扩大，除了俄罗斯矢车菊（Russian knapweed）外，还包括顶羽菊（Acroptilon repens (L.) DC.）、菊科（Asteraceae）菜蓟族（Cynareae）矢车菊亚族（Centaureinae）和刺头菊亚族（Carduinae）内的植物物种。对寄主对线虫感染的反应进行检查后发现，俄罗斯矢车菊是唯一高度易感的寄主植物。扩散矢车菊（Centaurea diffusa Lam.）为中度易感，而其他形成虫瘿的植物对矢车菊线虫具有抗性。
