在夏季，在商业光源处聚集诸如舞毒蛾的飞虫不仅对公共设施具有美学上的负面影响，而且还允许从明年开始在那里建立新的昆虫种群。尽管配备有发光二极管（LED）的节能型光诱捕器最近已用于控制农业中的害虫，但市场上可获得的免维护光诱捕器很少。根据野外调查的结果，我们制作了一个原型的光陷阱，在其中实现了昆虫对光照射角度和波长的偏好。田间试验表明，窄照射角的光比宽照射角的光更能吸引飞蛾。此外，有一个趋势，更少的飞蛾被收集时，荧光涂料被施加到飞行拦截板的表面，表明由照明和背景的高对比度是飞行飞蛾的首选。结合我们以前的研究结果，我们发现，蛾捕获的影响更多的是由修改的光设计，而不是由可见光波长的变化。一种半便携式光陷阱，命名为“栗原陷阱”后，其主要贡献者的发展，是由轻质塑料和太阳能驱动。该灯诱器是全方位的，无需维护，因此适合部署在休息区的后院以及房屋中进行长期的大型蛾采样。
Aggregation of flying insects such as gypsy moths at commercial light sources in summer not only has an aesthetically negative impact on public facilities but also permits the establishment of new insect populations there from the next year. Although energy-efficient light traps equipped with light-emitting diodes (LEDs) have recently been used for controlling pest insects in agriculture, there are very few maintenance-free light traps that are available on the market. Based on the results of field surveys, we fabricated a prototype light trap in which the preferences of insects for light irradiation angle and wavelength are implemented. Field experiments revealed that flying moths were attracted more to light with a narrow irradiation angle than to light with a wide irradiation angle. Moreover, there was a tendency for fewer moths to be collected when fluorescent paint was applied to the surface of the flight-interception board, indicating that a high contrast made by illumination and the background is preferred by flying moths. Taken together with our previous results, we found that the moth catch was influenced more by modification of the light design than by change in visible light wavelengths. A semi-portable light trap, named the “Kurihara trap” after the primary contributor to its development, is made of light-weight plastic and is driven by solar power. This light trap is omnidirectional and maintenance-free and is therefore suitable for deployment in the backyards of rest areas as well as at houses for long-term macromoth sampling.
