Cyphocleonus achates（Fahaeus）是一种欧亚大陆的根食象鼻虫，引入北美用于生物控制斑点矢车菊（Centaurea maculosa Lamarck）。Stinson et al.（1994）报道C.在欧亚大陆，刺蛾是矢车菊上最具破坏性的食根昆虫之一，应该是北美生物防治工作的一个有价值的补充。Stinson等人（1994年）描述了象鼻虫的生物学、宿主特异性和潜在影响。落叶松进入根皮层，在那里它们诱导形成明显的根瘿。老幼虫取食会造成很大的损害，特别是对小植物或含有几个幼虫的植物。象甲以幼虫在根部越冬，7月中旬至10月成虫羽化。成年象鼻虫很大（14毫米长），不会飞，以矢车菊叶子为食。象鼻虫一年发生一代。
Cyphocleonus achates (Fahaeus) is a Eurasian, root-feeding weevil introduced into North America for the biological control of spotted knapweed, Centaurea maculosa Lamarck. Stinson et al. (1994) reported that C. achates is one of the most damaging root-feeding insects on knapweed in Eurasia and should be a valuable addition to the biocontrol effort in North America. The biology, host specificity, and potential impact of the weevil were described by Stinson et al. (1994). Larvae mine into the root cortex where they induce formation of a conspicuous root gall. Feeding by older larvae causes much damage, especially to small plants or plants containing several larvae. The weevil overwinters as a larva in the root and emerges as an adult from mid-July to October. Adult weevils are large (14 mm long) and flightless, and feed on knapweed foliage. The weevil has one generation per year.
