1973 年，一种产瘿蝇 Urophora affinis Frfld. 被释放到蒙大拿州西部的一个地点，用于控制斑矢车菊（Centaurea maculosa Lam.）。共有 279 只 U. affinis 被释放到野外，其中 150 只被释放到野外笼子中。田间笼内的 U. affinis 种群在两年内显着增加，受感染的种子头从 15.2% 增加到 71.3% 就证明了这一点。 2年后，在距离初始释放点50 m处发现了野外释放的U. affinis虫瘿；整个田地里都发现了少量成虫。苍蝇的生活史与其寄主植物的发育密切同步。
A gall-producing fly, Urophora affinis Frfld., was released at a site in western Montana in 1973 for the control of spotted knapweed ( Centaurea maculosa Lam.). A total of 279 U. affinis was field-released while 150 were released into a field cage. The U. affinis population within the field cage increased significantly over a 2-yr period as evidenced by an increase of infested seed heads from 15.2–71.3%. Galls of field-released U. affinis were found at a distance of 50 m from the initial release point after 2 yr; adults were found throughout the field in small numbers. The life-history of the fly was closely synchronized with the development of its host plant.
