DINÂMICA E ESTRATÉGIAS DE MANEJO DO PERCEVEJO-MARROM (Euschistus heros) NA SOJA

Abstract

Brazil stands out as one of the world's leading agricultural powers, with a significant share in soybean (Glycine max) production. However, the crop is affected by a complex of pests, most notably the brown stink bug (Euschistus heros), a species native to the Neotropical region and highly adapted to soybean cultivation systems.

This insect is one of the main pests of the crop due to its direct feeding on the grains, causing significant productivity losses. The management of E. heros, traditionally based on chemical control, has shown reduced effectiveness due to the selection of populations resistant to different groups of insecticides, which has resulted in failures in pest control and increased production costs. In this context, this literature review aimed to analyze the records of E. heros resistance to insecticides and discuss its implications for integrated pest management (IPM) in soybean cultivation, with emphasis on sustainable management strategies, including rotation of modes of action, population monitoring, the use of the economic damage threshold, and the integration of control methods. It is concluded that the resistance of the brown stink bug constitutes a growing challenge for soybean farming, making it essential to strengthen IPM to ensure productivity and sustainability.
