Abstract

Abstract Global climate change and, specifically, rising temperatures, may increase the number of generations of necrophagous insects. The common green bottle fly Lucilia sericata (Meigen, 1826) (Diptera, Calliphoridae) ranks among the most important cosmopolitan necrophagous insects that utilize corpses and cause myiasis in farm animals and humans. Based on the data simulations, the use of accumulated degree-hours enables to calculate the number of generations of this forensically important species of blowfly with a greater accuracy than before, considering short-term increases of temperature at the boundary of the cold and warm seasons. The number of generations of L. sericata has increased from 7.65 to 8.46 in the Ukrainian steppe zone over the last 15 years, while the active developmental period of this species has increased by 25 days due to earlier start in spring. The average temperature increase of 1 °C increased the number of generations of L. sericata by 0.85. With a global climate change following the Representative Concentration Pathway (RCP) 4.5 scenario (average temperature increase of 2.4 °C), adopted by the Intergovernmental Panel on Climate Change, by 2100 the number of generations of L. sericata in a simulated ecosystem will increase by 2.0 to 9.0 generations per year.

环境温度升高对丝光绿蝇季节性代数的影响(双翅目，蛱蝶科)

摘要全球气候变化，特别是气温上升，可能会增加噬尸昆虫的世代数量。常见的绿瓶蝇Lucilia sericata（Meigen，1826）（直翅目，丽蝇科）是世界上最重要的尸食性昆虫之一，它们利用尸体并在农场动物和人类中引起蝇蛆病。基于数据模拟，考虑到寒冷和温暖季节边界温度的短期升高，使用累积度数小时能够比以前更准确地计算这种具有法律意义的重要物种的蝇类的世代数量。在过去的15年里，乌克兰草原地区的L.sericata的代数从7.65代增加到8.46代，而由于春季开始较早，该物种的活跃发育期增加了25天。平均温度升高1°C使蚕桑的世代数增加了0.85。随着全球气候变化遵循政府间气候变化专门委员会采用的代表性浓度路径（RCP）4.5情景（平均气温上升2.4°C），到2100年，模拟生态系统中的蚕桑L.世代数量将每年增加2.0至9.0代。
