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)

Abstract

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. Xerophilic Ae. rostrata colonized the overgrown burnt area ten years after the fi re, refl ecting the process of xerophylization of the post-pyrogenic ecosystem in forest-steppe conditions.
