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

我的重点是开发一种防治十字花科主要害虫菜青虫的方法所需的知识，菜青虫是十字花科的一种主要害虫，包括许多重要的经济蔬菜作物，并阐明菜青虫和十字花科植物的生物相互作用。与其他4种十字花科植物相比，甘蓝成虫更受欢迎。此外，还对甘蓝提取物中的4种引诱剂进行了鉴定。此外，还阐明了甘蓝释放的最大挥发性浓度时间与菜青虫的最大偏爱百分率几乎相同。

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.
