ESTUDOS PARA O MONITORAMENTO DO PERCEVEJO MARROM Euschistus heros EM LAVOURAS DE SOJA

Abstract

The brown stink bug is considered a pest of great importance in the soybean crop, its severity is quantitative and qualitative. Given the current management scenario of this pest, failures in control could be observed, coupled with the non-application of MIP techniques. The present study aims to develop new monitoring techniques combined with studies on the behavior of surveying population fluctuations. For the study of behavior, lights of different colors were tested on the attractiveness of the stink bug, different later models of traps were developed in the 2019/20 and 2020/21 harvests for evaluations of catches by attractiveness, in the last study in the 2020/21 harvest they were carried out insect sampling through imaging throughout the development period of the soybean crop, to form a database of soybean development stages and as pests that occur during the harvest. In behavioral studies, field families were more attracted to light stimuli, the green color attracted the greatest number of male field insects. Fabric traps capture more insects compared to those made from PVC. The population of Euschistus heros monitored by images had the same representation as a crash panorama, enabling effective monitoring.
