身近な昆虫を材料とした

配偶行動に関する研究
社会性進化に関する研究
形態と行動に関する研究

など，野外や室内での観察や操作実験を中心とした研究（材料は要相談）

Message

その間，アシナガバチを材料とした昆虫の社会性進化の研究や，熱帯・亜熱帯域の世界的なサツマイモ害虫であるゾウムシ類の，不妊虫放飼法を利用した個体群管理に関する研究に取り組んできました．テーマも材料も全く異なっていますが，何れの研究でも，対象とする昆虫をよく観察することが新たなアイデアを生み出すきっかけとなりました．

みなさんが昆虫のある形質（行動や形態）の適応的意義を明らかにしたい場合，先行研究にもとづき仮説をたて，野外観察や室内での飼育・観察，操作実験によって検証することになります．研究を開始する際には，どこから手を付ければよいのかよくわからないかもしれませんが，まずはしっかり虫の生き様を観察することが，研究の糸口を見つける近道なのかもしれません．

「最も基礎的な研究が最も役に立つ研究」という言葉が示すように，一見，応用的にも見える害虫管理のような研究課題も，実は基礎研究の集積なのです．昆虫の行動の理解は，生物多様性の理解だけでなく，その知見を活かした害虫管理技術の確立につながり，我々の生活をより豊かなものにしてくれるものと考えています．

Self introduction

I am an evolutionary biologist fascinated by behavioral ecology, and my research has mostly focused on insects.

I was born in Hyougo, Japan in 1972.

Introduction

Today's global climate change and increasing people's movement are threatening our lives through the invasion and distribution of vectors and pests. In order to solve these problems, knowledge of insect ecology and management by environmentally friendly methods becomes important.

I have been studied based on the keyword "evolution of insect eusociality", "pest management using sterile insect technique", "ecological study of sweet potato weevils". Currently, in addition to these studies, we are also expanding to pollination insects, invasive insects and insects closely related to agriculture in Hokkaido. Studies conduct in and out laboratory to learn the evolution and adaptation of behavior, shape, coloration of target insects. My study aim is to understand the balancing the ecology through the interactions between species and community.
