Abstract

The soybean crop occupies a prominent place in Brazilian and world agribusiness, being one of the commodities that generate the most income for Brazil. However, phytosanitary problems, such as pest attacks, hinder economic exploitation and cost production. In order to control pests, there is a need to develop new tools to enable effective management of pests and also to avoid the excessive use of insecticides, which result in the selection of individuals resistant to the active principles, reduction of the presence of natural enemies and contamination the environment and man. In the current agricultural scenario, the brown bug, Euschistus heros, appears as a key pest of soybeans, causing severe losses in yield and quality of crop production. However, one of the promising strategies currently used is the adoption of integrated pest management, with emphasis on the use of biological control techniques. Currently, several studies have been conducted with the parasitoid of Telenomus podisi eggs in the control of E. heros. However, in order to guarantee the effectiveness of the applied biological control program, there is a lack of information on release techniques, such as the ideal season, frequency of releases and the time the parasitoid stays in the field. As a result, it is essential to evaluate the best release time in relation to the phenological stage of the culture, in order to establish the frequency of the releases, as well as to evaluate the period of the permanence of T. podisi in the field after the release. These parameters are fundamental for the commercial development of technological packages, aimed at the recommendation of the use of T. podisi in the applied biological control of the complex of phytophagous bugs in the soybean crop.
