| Summary: | The current paper has presented the generalized research data of the species composition of grain bugs in the winter common wheat agrocenosis during the spring-summer period in the forest-steppe of the Samara region in 2021–2023. The purpose of the study was to identify the species composition of grain bugs according to the phenophases of winter common wheat development in the spring-summer vegetation period. For this purpose, there have been recorded imago and larvae of grain bugs by mowing with an entomological net in different phenophases of winter wheat development in the experimental plots of the Povolzhsky RIBSP. The species composition was determined in the laboratory. The weather conditions of the research period were contrasting. The years of 2021, 2023 were dry and the year of 2022 was cool with abundant precipitation in the first half of the spring-summer vegetation period. There were identified 2 species of grain bugs in a tillering stage, 4 species in a booting stage, in the stages ‘heading – full ripeness’ there were 6 species of bugs belonging to 4 families: Pentatomidae (Dolycoris baccarum L., Aelia acuminata L.), Scutelleridae (Eurygaster maura L., Eurygaster integriceps Puton.), Berytidae (Notostira erratica L.), Miridae (Trigonotylus ruficornis Geoffr.). In a heading stage, the dominant species was Aelia acuminata (55–38 %). During the ripening stage (milk, wax, dead ripeness), the dominant species was Eurygaster integriceps Puton. (36–51 %). Imago and larvae of the Trigonotylus ruficornis Geoffr. and Dolycoris baccarum L. bug were found in the agrocenosis of winter common wheat at all stages of wheat development. Eurygaster integriceps and Aelia acuminata were found on the crops starting from a booting stage, Eurygaster maura and Notostira elongata were found on the crops starting from a heading stage of winter wheat. |
