The number of insect species has explosively increased for more than 450 million years, which counts as the most flourished species on the current earth. One of the most critical events for such extensive diversification of insect species is “adaptive radiation.” This event has occurred by the adaptation of plant-feeding (herbivorous) characteristics. The emergence of herbivorous insects brings interesting feeding habitats in insect species such as herbivores, carnivores, and omnivores. To understand this feeding habitat in insects, we are trying to solve many questions, dietary recognition, selection, metabolisms….

Introduction

Biologically active compounds contributte to most of all physiological and biological events. Discoveries and functional studies of bioactive compounds experienced during my graduate student life encompass my current research interests.
Our current research projects aim to elucidate innate behavioral control by bioactive compounds in insects. Mainly, we focus on the fundamental feeding selective behavior by insects. For satisfying the elucidation, we investigate the cricket behavior, which has omnivorous characteristics. This cricket provides many exciting issues, body color, individual recognition, cannibalism, in addition to feeding selection controlled by endocrine factors, nervous systems, metabolisms.. We hope that chemical biology, molecular biology, and borderless fields will address such exciting issues.

  • Many crickets in our cricket-rearing room

  • International meeting with scientists in the entomological endocrinology.
