Outline of Final Research Achievements

Currently, Asian gypsy moths (Lymantria dispar) are wary of invasion outside the habitat area such as North America by ships. Laboratory experiments were conducted with the objective of developing effective illumination techniques for adult activity. When illuminated with LED in the dark period, the activity was significantly suppressed with yellow 200 mW / m 2, light yellow 10 mW / m 2, light yellow 200 mW / m 2 irradiation. Compared to untreated, the number of individuals that spawned significantly at yellow 200 mW / m 2, but no significant difference was detected in other illumination zones. The most suitable for suppression of behavior of female adults is considered to be 200 mW / m 2 of yellow LED, indicating that irradiance is related to activity.
