Insects face the challenge of locating hosts in a complex odor landscape. Plants face the challenge of trying to lure pollinators while, simultaneously, deterring herbivores. Although this predicament may be quite common, it has rarely been investigated. Through a combination of analytical chemistry and field research the components of the scent blend of Cirsium arvense, Canada thistle, important for insect attraction will be investigated, and mechanisms by which floral volatile emissions are modified to avoid attracting detrimental insects will be identified. C. arvense is in many ways well suited for this study. Because it is dioecious, scent, which can act as a long distance attractant for pollinators, becomes paramount to extending its distribution. Additionally there are distinct selection pressures on the two sexes by beneficial and detrimental floral visitors. Preliminary data demonstrates a difference in both insect visitation and scent between male and female plants.

昆虫面临着将宿主定位在复杂的气味景观中的挑战。 植物面临着试图引诱传粉媒介的挑战，同时阻止了草食动物。 尽管这种困境可能很普遍，但很少对此进行调查。 通过分析化学和现场研究的结合，将研究加拿大菊花菌的气味混合物的组成部分，对昆虫吸引力很重要，并且将修改花卉挥发性排放以避免吸引有害昆虫的机制。 C. Arvense在许多方面都非常适合这项研究。因为它是富裕的，所以可以充当传粉媒介的长距离吸引剂，因此对于扩展其分布至关重要。 此外，有益和有害的花卉游客对两性有明显的选择压力。 初步数据表明，雄性植物和雌性植物之间的昆虫探访和气味有所不同。
