根据1949-2004年在日本中部关西地区采集的265具标本，分析了六斑小菜蛾的采集季节的长期变化。结果表明，夏季7、8月份的采集记录呈下降趋势，2000-2004年没有夏季记录。同时，关西地区年平均气温和夏季气温呈上升趋势，夏季湿度呈下降趋势。因此，由于最近的气候变暖，六斑沼虾在夏季的活动将受到限制。
Long-term changes in the collection season of Menochilus sexmaculatus (Fabricius) were analysed based on 265 specimens collected from the Kansai district, central Japan, during 1949-2004. Results show that collection records in the summer months, July and August, decreased during this period, and that there were no summer records from 2000 to 2004. Concurrently, the annual mean and summer temperatures tended to increase and summer humidity decreased during this period in the Kansai district. Thus, the activity of M. sexmaculatus would be limited in summer because of the recent climate warming.
