Bioresources and Management

The number of exotic species introduced in novel habitats has recently increased with increasing trade and tourism. It becomes a serious problem when they displace indigenous species, cause damage to agriculture, or disrupt native ecosystems. Exotic species that cause negative impacts on human beings, animals, crops, or environments after introduction into the novel habitats-in other words, when exotic species become pests in the new habitats-are referred to as invasive pests. In our laboratory, we conduct research on the mechanisms underlying how exotic species become invasive pests-through the steps of introduction, establishment, spread, and outbreak, and the effects of invasive species on agro- and natural-ecosystems. Our study also aims at the improvement of plant quarantine systems to prevent the introduction of exotic species and the development of biological control programs for invasive pests. Basic studies of behavior and ecology in parasitic wasps have been conducted to develop an effective biological control strategy.

Insect ecology, insect behavioral ecology, insect physiology, and insect pest management are our research approaches. We conducted field surveys, not only in Japan, but also in Southeast Asia, Africa, and the USA, as well as laboratory experiments to elucidate the ecology and physiology of target insects. In addition, our mission is to develop an international network and administrative system for plant protection in Asia and other global regions.

We welcome prospective students (graduate students) who are interested in working on basic research such as insect behavior, ecology and physiology, and its applications to pest management.
