“…They cause severe damage to both the yield and quality of the harvested product [3,4]. Among the phytophagous stink bugs that damage soybean crops, the brown stink bug, Euschistus heros (Fabricius, 1794) (Hemiptera: Pentatomidae), is the most abundant species in the Neotropical region, including Brazil [5], Argentina, Paraguay, Panama, Uruguay, and Bolivia [3,6,7].…”

Brazil is one of the largest producers of pulses globally, and soybean ranks highly in terms of production. However, pests increase crop production costs and affect oilseed production and quality. Pests are primarily controlled by chemicals, leading to changes in insect pest populations. For example, secondary pests can become primary pests because of the selection of resistant insects and the elimination of natural enemies. Farmers have widely accepted biological control because of its high control efficacy and low environmental contamination risk. Two successful biological control programs in soybean used Telenomus podisi Ashmead (Hymenoptera: Platygastridae) to manage the Neotropical brown stink bug, Euschistus heros (Fabricius) (Hemiptera: Pentatomidae), and Trissolcus basalis (Wollaston, 1858) (Hymenoptera: Scelionidae) to manage the southern green stink bug, Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae), when these pests were the most abundant in soybean-producing regions. To release parasitoids, rearing protocols must be developed in order to optimize production. This study evaluated the effect of temperature on the biological characteristics of T. podisi and T. basalis when fresh or frozen E. heros eggs were provided. Fifty fresh or previously frozen eggs were placed with parasitoids for 24 h in a climate chamber (25 ± 1 °C, 70 ± 10% RH, and 14-h photophase). At the end of this period, the eggs were transferred to other chambers and maintained at different temperatures (19, 22, 25, 28, 31, and 34 ± 1 °C, 70 ± 10% RH, with a 14-h photoperiod). The number of emerging adults from eggs parasitized by T. basalis was lower than that from eggs parasitized by T. podisi. Differences in T. basalis and T. podisi parasitism were observed depending on whether the E. heros eggs were frozen or fresh, but neither development nor emergence were affected. The duration of egg–adult development and the longevity of the two parasitoids were inversely proportional to the temperature increase. The sex ratio of T. basalis and T. podisi progeny was not affected by different temperatures or by the use of frozen or fresh eggs. The estimated number of both parasitoids’ generations corresponded with temperature, reaching 14–15 generations/cycle of soybean for Rio Verde, GO, and 12–14 generations/cycle for Barreiras, BA. Given these characteristics, we conclude that a biological control program using T. podisi can benefit large areas of soybean production by controlling the eggs of phytophagous bugs in soybean crops.

“…Euschistus heros (Fabricius, 1794) (Hemiptera: Pentatomidae) is the most abundant and prevalent species in areas cultivated with soybeans in Brazil (Panizzi et al, 2012;Krinski et al, 2013) Bedbugs occur in soybean at all stages and are harmful from the beginning of pod formation until grain maturity (Zambiazzi et al, 2012). The damage caused by E. heros when uncontrolled can get up to 30% on soybean (Vivan & Degrande, 2011).…”

To deploy the appropriate management of adults and nymphs of Euschistus heros (Fabricius, 1794) in soybean, we need to construct a sampling plan that allows estimate population density quickly and accurately. This research aimed to perform sequential sampling of adults and nymphs of E. heros in Bt and non-Bt soybeans. For the evaluations we used the method of cloth-to-hit, two regions in which the sample areas where we collected a sample randomly per plot of each trial were installed. Evaluations were performed at 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98 days after emergence (DAE). We adopted the model of contagious distribution, it was constructed a sequential sampling plan in accordance with the Sequential Probability Ratio Test (TSRP). The adopted control level two bugs (adults and nymphs) per cloth beat. The analysis showed two lines of decision: the upper, which is the condition that the adoption of a method of control is recommended, defined by S1 = 6.2449 +0.14244 n; and below, representing that the adoption of some method of control is not recommended, defined by S0 = -6.2449 +0.14244 n. The sampling showed a maximum expected number eight samples to determine the need or otherwise of control. For management based on economic injury level, the expected number of sample units is 17, indicated by the Sequential Probability Ratio Test Wald curve.

O percevejo-marrom Euschistus heros é considerado uma das principais pragas no Brasil por causar prejuízos em diversas culturas. Atualmente, a principal forma de controle é o uso de inseticidas químicos, no entanto, o uso excessivo resulta no desenvolvimento de populações resistentes e contaminação ambiental. Devido a isso existe a necessidade de explorar novas alternativas de controle mais sustentáveis, como os agentes biológicos. Dentre esses, bactérias entomopatogênicas têm comprovada atividade tóxica em diversas famílias de insetos e ácaros, porém há carência de pesquisas para o controle desse percevejo. Portanto, o objetivo deste trabalho foi avaliar bactérias com potencial de controle do percevejo-marrom. Para isso, foi realizada uma pré-seleção representada por 125 isolados bacterianos que foram avaliados em condições de laboratório.
