Brazil is one of the largest cereal producers in the world and soybeans occupy a prominent place in this production. However, the pest complex costs the production cost of the crop, directly affecting the production and quality of the grains. Chemical control is the main management tactic used, which leads to an imbalance in the population of insect pests, causing pests previously considered secondary, to assume key pest status due to the selection of resistant insects and the death of one of the main suppression factors, the natural enemies. With this, biological control becomes a management tactic with potential and use for pest reduction, which has been accepted by farmers because it has high efficacy in the control, with low risk of contamination of the environment and man. This characteristic encourages research and production of new biological products. In the soybean complex, one of the main pests is the brown bug, Euschistus heros (Fabricius) (Hemiptera: Pentatomidae), which directly impacts the production and quality of the grains. However, in recent years, strategies of applied biological control have been studied, such as the use of the natural enemy Telenomus podisi Ashmead (Hymenoptera: Platygastridae). However, for mass production of T. podisi it is necessary to establish the methods of production of the parasitoids, on a large scale, without affecting the biological characteristics of the parasitoid. Therefore, it is fundamental to evaluate the potential of egg storage in the host at low temperatures, as well as to determine the ideal temperature and the best way of stocking the eggs, in order to increase the availability time of this product, which are fundamental steps for the commercial development of technological packages for the recommendation of the use of T. podisi in the applied biological control of the bug bugs complex in the soybean crop.
