Research Projects

The chemical factors which regulate the host selection behavior of phytophagous insects have been investigated. Influence of light on physiology of insects has also been investigated.

  1. Feeding and oviposition stimulants for phytophagous insects.
  2. Host-finding mechanism of coleopteran phytophagous insects.
  3. Olfactory responses of phytophagous insects to plant volatiles.
  4. Attractants and repellents to stored product insects.
  5. Lethal effects of short-wavelength visible light on insects.

  • Lethal effects of blue light on insects

Our research team revealed the strong lethal effect of short-wavelength visible light (blue light: 400–500 nm) on insects. That is, we found that blue light irradiation by using a common light-emitting diode (LED) can kill the eggs, larvae, pupae, and adults of various orders of insects. Our findings will provide clean and safe pest-control technique as well as important information on the hazards of exposure to visible light.
