Instructable research topic for doctoral thesis

  • 上記、農業害虫・衛生害虫・貯穀害虫を対象とした害虫防除研究を実施していますが、この他に興味のある研究材料や防除技術、研究分野があればぜひ提案してください。どういった方法論で希望するテーマを形にできるか一緒に考えましょう。どうせやるなら、ワクワク感を持って没頭できる楽しい卒論テーマ選びをしたいと考えています。

農業害虫管理学分野では「潜在収量レベル」という言葉があります。これは、防除を実施することで損失をゼロにした場合の農作物の収量のことです。現状では、防除を実施しても30〜50%が病害虫の被害で損失しているとされており、防除技術のイノベーションにより、これだけの増収が可能であることを示してます。我々は、この潜在収量レベルにいかに近づけるか、害虫による被害をいかに軽減するか、試行錯誤を重ね日夜研究を進めております。
​当ラボの上位目的として「食糧安定供給」と「感染症制圧」とがあげられますが、いずれも人類の生存や豊かさにつながるテーマです。これらの課題に対して害虫の防除というアプローチから問題の解決に取り組んでいます。

Self introduction

I’m from Sapporo. I played basketball in junior high school, did alpine skiing in high school, and did freestyle kayaking and Western riding at university. Since entering the workforce, I’ve enjoyed playing ice hockey. The lab I chose was one where I would be able to research phytopathology. But at a tremendous turning point, my supervisor changed his specialty and before I knew it, I’d become a specialist in applied entomology. I’m an Obihiro University of Agriculture and Veterinary Medicine faculty member who’s also an alumnus, one of few such faculty members in recent years. I’m interested in DIY, and I’ve been hooked on cooking, camping and wood carving.

Introduction

Research materials handled in this laboratory are largely divided into three types: agricultural pests, medical insect pests and stored-grain insect pests. I conduct research on how to control these pests, how to cause them to die and how they change upon death. Basically, most of my research is on biocontrol using insect parasites. But as long as I can kill pests beautifully or otherwise render them harmless, I’ll use whatever means I can find, such as natural enemies, plant pesticides and insect light traps.

I’m currently engaged in the following: (1) research on changes in plant nutrient components that could change the behavior of insect vectors and research on the effect of that change on the efficiency of the insect vector-mediated transmission of plant viruses, (2) research on the phenomenon whereby vector mosquitos infected with entomopathogenic fungi are alive but are no longer effective as vectors, and the clarification of the mechanism behind that ineffectiveness, (3) the exploration of control methods targeting the eggs of whiteflies, which are agricultural pests, and clarification of the insecticidal mechanism, (4) the development of crop cultivation techniques to reduce insect pest damage on stored grain in Africa, and (5) the exploration of plant components that could have repellent/insecticidal activity on stored-grain insect pests in the Republic of Malawi.
