Insect outbreaks often occur in the absence of natural enemies and in the presence of excess suitable host materials. Outbreaks of gypsy moths are especially problematic in remote areas located in high-latitude regions in Japan because the majority of adults emerge during the short summer season and initiate synchronous mass flight toward artificial lights. The aggregation of moths in public facilities not only is an annoyance to visitors but also permits the establishment of new populations the following year. The aim of this study was to establish a method to reduce the numbers of large moths that are attracted to lights in the rest areas of expressways in Hokkaido based on the results of research on their behavioral ecology and physiology. First, we conducted extensive insect surveys using light traps that emit light at different wavelengths; the traps were set along the expressways in the summers of 2014–2018. The insects attracted to the light were roughly classified into those showing a preference for broadband light wavelengths (from UV-A to green) and short light wavelengths (from UV-A to blue). The former included aquatic insects and winged ants, and the latter included moths and beetles. Next, we analyzed correlations between moth emergence and daily meteorological data. When gypsy moths were abundant during an outbreak, the daily catch of gypsy moths was positively correlated with the highest ambient temperature on the catch day but not with the visibility range, wind speed, or moon phase. In contrast, the daily catch of oak silkmoths did not correlate with any of these parameters. Our results provide guidance for the management of forest insects inhabiting cool-temperate to subarctic regions based on light wavelengths with reference to weather variables.

通过产学合作管理高速公路上的飞虫:评估光波长和气象因素对昆虫吸引力的影响
昆虫爆发通常发生在没有天敌和存在过量合适宿主材料的情况下。吉普赛蛾的爆发在日本高纬度地区的偏远地区尤其成问题,因为大多数成虫在短暂的夏季出现并开始同步大规模地向人造光飞行。公共设施中飞蛾的聚集不仅对游客来说是一种烦恼,而且还允许在第二年建立新的种群。本研究的目的是根据对行为生态学和生理学的研究结果,建立一种方法来减少北海道高速公路其余区域被灯光吸引的大型飞蛾的数量。首先,我们使用发射不同波长光的光阱进行了广泛的昆虫调查;这些陷阱是在 2014-2018 年夏天沿高速公路设置的。被光吸引的昆虫大致分为偏好宽带光波长(从UV-A到绿色)和短光波长(从UV-A到蓝色)的昆虫。前者包括水生昆虫和有翅蚂蚁,后者包括飞蛾和甲虫。接下来,我们分析了飞蛾出现与每日气象数据之间的相关性。当暴发期间舞毒蛾大量出现时,舞毒蛾的日捕捞量与捕捞日的最高环境温度呈正相关,但与能见度、风速或月相无关。相比之下,橡树蚕蛾的每日捕获量与这些参数中的任何一个都不相关。
