Experience of using a Malaise trap to analyze the seasonal activity of some insects

Various methods of insect catching are used to monitor seasonal activity. The Malaise trap is not always popular with researchers because it is bulky and difficult to maintain. Seasonal experiments were conducted to analyze the possible use of the Malaise trap in studying the activity of four groups of insects: Orthoptera, Hemiptera (Heteroptera), Mordellidae (Coleoptera), Asilidae (Diptera). From May to October 2021, 914, 101, 662, and 173 individuals were recorded in the Malaise trap, respectively. For all groups, except Hemiptera, the maximum abundance during the season was revealed. The Malaise trap can be successfully used to study the seasonal dynamics of the number of species of different insect groups.
