Identification of Pieris rapae attractant components in Brassicaea plants and elucidation of biological interaction both P. rapae and Brassicaeae plants.

我专注于开发防治破坏性昆虫Pieris raiscrucivora所需的知识，Pieris raiscrucivora是包括许多经济上重要的蔬菜作物在内的豆科植物的主要害虫，并阐明了P. raiscrucivora和豆科植物的生物相互作用。雌虫对甘蓝的选择性高于其它4种豆科植物。此外，还对甘蓝提取液中的4种引诱剂进行了初步的测定。甘蓝挥发物释放最大浓度的时间与油菜潜蝇的最大偏好百分率基本一致。

I focused on the knowledge needed to develop a control method against a destructive insect, Pieris rapae crucivora, which is a major pest of the Brassicaceae family that includes many economically important vegetable crops, and elucidation of biological interaction both P. rapae and Brassicaeae plants. Adult females were preferred cabbage to other 4 kinds of Brassicaeae plants. In addition, 4 attractants in cabbage extract were estimated. Moreover, it was clarified that time emitted maximum volatile concentration from cabbage was almost same as maximum preference percentage of P. rapae.
