Number of different insecta groups and its dynamics on burned areas after megafires (second year of study)

Abstract

The paper describes the results of studying the insect fauna after the megafires of 2021. Studied of 30,721 individuals from 10 insect orders were obtained for study in 2023, the second year after the megafires. We have established that in the traps were dominated by taxa from the orders Lepidoptera, Coleoptera, Neuroptera, and Hymenoptera. It is shown that the remaining orders were relatively few in number and occurred as single specimens. It is noted that the number of species belonging to the orders Heteroptera, Neuroptera, Lepidoptera, Hymenoptera, Mecoptera, and Trichoptera increased in 2023 in comparison to the previous year. As a result of this the number of individuals of the Heteroptera (4.8 times), the Neuroptera (3.2 times), and the Lepidoptera (2.0 times) increased significantly in the second year after megafires. It is shown that the seasonal dynamics was characterized by the configuration observed in insects native to temperate zones, with a single maximum observed in either July or August.
