A lab studying biological control, which suppresses pests using natural enemy insects.

AboutAbout the lab
Exploring how natural enemy insects can suppress pests
The lab studies the biological control of pests using parasitoid and predatory natural enemy insects, from both basic and applied perspectives.
Natural enemy insects include predators, which capture and eat other insects, and parasitoids, which lay eggs on or in other insects.
Prof. Tuda studies population fluctuations and evolution of pests and their natural enemies, as well as pest control using nanomaterials.
Associate Professor Ueno studies the behavior, ecology, and life history of parasitoid wasps, and also works on pest control methods that use natural enemies.
Key terms
- Natural enemy insect
- An insect that causes other insects to die. Some are predatory and some are parasitoid.
- Biological control
- A method of suppressing pest outbreaks by using the activity of living organisms, such as natural enemies.
- Parasitoid wasp
- A type of wasp that lays eggs on or in other insects; the hatched larvae eat the host completely.

ResearchResearch themes
The lab studies biological control, which suppresses pests using parasitoid and predatory natural enemies. It aims to clarify the behavior, ecology, and life history of natural enemy insects and apply that knowledge to methods of suppressing pests.
*Illustrative imageBiological control of pests using beneficial insects
This research aims to suppress pests using beneficial insects. Keywords in the researcher information include parasitoid wasps, environmentally friendly agriculture, food production, and functional biodiversity.
*Illustrative imageManipulating the reproductive behavior of beneficial natural enemy insects
The research theme is manipulating the reproductive behavior of beneficial insects that suppress pests. Keywords in the researcher information are mass rearing and production costs.
*Illustrative imageBehavioral ecology and life-history evolution of parasitoid wasps
The lab investigates the behavior, ecology, and life-history evolution of parasitoid wasps. Keywords listed in the researcher information include learning, sex ratio, and environment.
*Illustrative imageEvolutionary maintenance of polymorphism within populations
The lab examines, from an evolutionary perspective, the mechanisms that maintain differences in individual traits (polymorphism) within a single population. Keywords in the researcher information include antennae and sexual conflict.
