In mountainous districts of Japan, fruit-piercing moths such as Adris tyrannus amurensis STAU-DINGER, Calpe gruesa DRAUDT, Oraesia excavata BUTLER and others are important nocturnal pests for various fruits. The authors studied some fundamental problems of the orchard illumination, one of the useful methods for controlling them, by means of many experiments and observations. The results obtained are summarized as follows. 1. According to many experiments, the relationship between the moths'activities and the physiological condition of compound eyes, namely dark or light adaptation, was considered, and it was recognized that their activities were controlled remarkably in the eye condition of light adaptation, even if under dark environment. 2. Under the illuminated environmet the activities of moths with light adaptation eyes were inhibited more remarkably. It is considered as an important reason for the illumination effects. 3. The influence of light elements, such as wave ength, brightness, illumination level and light energy, on the change to light adaptation from dark adaptation were examined by the filter method mainly. From these experiments both the wave length and the illumination level were pointed out as important elments concerning the promotion of light adaptation. It is concluded that the range between blue and yellow of wave length is more effective as well as higher illumination level in general. 4. In order to compare with the practical effects of different wave length, the authors practised some field experiments by using of several kinds of fluorescent lamps. Among these lamps, the yellow colored lamp, the dominant wave length is about 580mμ, was most effective due to the inhibition of moths'coming and piercing. 5. Considering the influence of illumination on other nocturnal pests in orchards, the authors recommend the yellow colored lamp mentioned above or the incandescent lamp as an available light for the orchard illumination.
