他1929年出生于大坂，在第二次世界大战中幸存下来，作为一个年轻的少年，他总是把筷子放在口袋里，这样如果他要找到食物，他就可以吃了。1954年毕业于京都大学，后进入博士研究生院。该项目由Syunro Utida教授领导，他因在豆象鼻虫种群动态方面的工作而闻名国际。1959年，他被农林水产省（MAFF）聘为阿索和歌山农业实验站的负责人，负责调查入侵的Nezara viridula。他鼓励许多学生和专业人士谁来与他合作，虽然合作是罕见的日本科学在那个时候。在接下来的七年里，Kiritanisensei（我们中的许多人都和他一起工作）发表了43篇关于种群动态、种间交配、范围扩张和颜色多态性的合作学术论文。在这个过程中，他完成了博士学位。1966年，农林水产省将桐谷千成调到高知县研究站，担任水稻害虫抗药性研究室主任。当时的农药抗性研究主要集中在敏感性试验、人工选择和农药降解酶活性等方面。而不是采取这些方法，桐谷老师的理由是，害虫获得抗药性，因为他们喷洒杀虫剂，所以如何才能减少杀虫剂的使用在水稻？因此，开始了对水稻主要害虫之一的稻叶蝉种群动态的深入研究，发现蜘蛛可以在不使用杀虫剂的情况下控制这些种群。这种对蜘蛛重要性的早期认识
Born in Osaka in 1929, he survived World War II as a young teenager, always keeping his chopsticks in his pocket so that if he were to find food, he could eat. He graduated from Kyoto University in 1954, then entered the Ph. D. program under Professor Syunro Utida, internationally known for his work on the population dynamics of bean weevils. In 1959, he was hired by the Ministry of Agriculture Forestry and Fisheries (MAFF) as Chief of the Wakayama Agricultural Experiment Station at Asso to investigate the invasive Nezara viridula. He encouraged collaboration among the many students and professionals who came to work with him, although collaboration was uncommon in Japanese science at that time. During the next seven years, Kiritanisensei (as the many of us who worked with him would call him) published 43 collaborative academic papers on population dynamics, interspecific mating, range expansion, and color polymorphism. In the process, he finished his Ph. D. thesis from Kyoto University.In 1966, MAFF transferred Kiritanisensei to the Kochi Prefecture Research Station as Director of the laboratory for research on pesticide resistance of rice pests. Pesticide resistance research at that time focused on susceptibility tests, artificial selection, and insecticide-degrading enzyme activity. Instead of taking these approaches, Kiritani-sensei reasoned that pests acquire resistance because they are sprayed with insecticides, so how can insecticide use be reduced in rice? Thus began an intensive study of the population dynamics of rice leafhoppers, one of the main rice pests, leading to the discovery that spiders could control these populations without insecticides. This early recognition of the significance of spiders
