Usman forest

Xerophilization as a formation vector of the postpyrogenic complex of hemipteran insects (Heteroptera) in the conditions of the Eastern European forest-steppe (on the example of the Usman forest, Voronezh region)

The article analyses the current composition of the complex hemipteran insects (Heteroptera) after the fi re in 2010 in the Usman pine forest (Voronezh region) based on materials collected and counted at the post-pyrogenic succession monitoring polygon with an area of 84 hectares in 2021–2022. The infl uence of microrelief and phytocenotic heterogeneity on the structure of Heteroptera communities was assessed within three accounting areas, 100 sq. m each, located on three lines of the polygon.

Dynamics of the populations of stink bugs of the genera Aelia and Neottiglossa (Heteroptera, Pentatomidae) in overgrown with vegetation burnt areas of the Usman Forest (Voronezh region)

Based on quantitative counts of the abundance of four species of the genera Aelia and Neottiglossa (Heteroptera, Pentatomidae), the process of formation of their populations in the overgrown burnt areas of the Usman Forest (Voronezh region) after a fi re in 2010 was modeled. It has been established that mesoxerophilic species Ae. acuminata and N. leporina appeared in the formerly burnt areas 5–6 years after the fi re. The mesophilic species N. pusilla is a permanent inhabitant of ecotone biotopes and has not shown a tendency to colonize the formerly burnt areas.
