Forest fires have a significant impact on forest fauna, killing not only mammals and birds, but also less noticeable representatives of forest fauna - insects. Existing research have mainly studied the effects on vertebrate taxa, but the data on the effects of fires on the number of insects living in forests is currently insufficient to cover all the groups. The research presented in this paper examines the immediate impact of forest fires on the number of adults in mosquito populations (Culicidae) in burned areas of the boreal forest. The data were collected in the boreal forests of Eastern Siberia, in the Republic of Sakha (Yakutia). Field survey was conducted in ten forest areas, including five recently burned and five unburned areas. Mosquitoes were caught in flight and counted during daylight hours within the time span of 7 days after the fire. We compared the data obtained from burned and unburned adjacent forest plots, which allowed us to establish the level of immediate impact of forest fires on the abundance of adult mosquito populations in the burned plots of the boreal forest. In all five pairs of forest plots, a decrease in the abundance of adult mosquitoes was noted, within the range of 86.6-93.9%. The data clearly show a lower number of adult mosquitoes for several days after the forest fire. The results obtained are of interest for further studying, regardless of the medical significance of mosquitoes, with consideration of their role in boreal ecosystems. This study is planned to be continued over the next few years in order to obtain new data on the impact of forest fires on mosquito populations in a medium and long term, which will allow us to form a broader vision of this problem.
森林火灾对森林动物群有重大影响,不仅会杀死哺乳动物和鸟类,还会杀死森林动物群中不太引人注意的成员——昆虫。现有研究主要关注对脊椎动物类群的影响,但关于火灾对森林中昆虫数量影响的数据目前还不足以涵盖所有类群。本文所呈现的研究考察了森林火灾对北方森林烧毁地区蚊子种群(蚊科)成虫数量的直接影响。数据收集于东西伯利亚萨哈共和国(雅库特)的北方森林。在十个林区进行了实地调查,包括五个最近被烧毁的地区和五个未被烧毁的地区。在火灾发生后的7天内,于白天对飞行中的蚊子进行捕捉并计数。我们比较了从相邻的烧毁和未烧毁森林地块获得的数据,这使我们能够确定森林火灾对北方森林烧毁地块中成年蚊子种群数量的直接影响程度。在所有五对森林地块中,都观察到成年蚊子数量减少,减少幅度在86.6%至93.9%之间。数据清楚地表明,森林火灾后的几天内成年蚊子数量较少。无论蚊子的医学意义如何,考虑到它们在北方生态系统中的作用,所获得的结果对于进一步研究都具有重要意义。本研究计划在未来几年继续进行,以便获得关于森林火灾对蚊子种群中长期影响的新数据,这将使我们对这个问题有更全面的认识。
