Resumo: | The neotropical brown stink bug Euschistus heros (Hemiptera: Pentatomidae) is one of the most important pests in soybean and knowledge of its distribution is necessary to determine the moment of control and enable the appropriate use of strategies to avoid production losses. This research aimed to study the temporal variation and the spatial distribution of E. heros in soybean. The study was carried out in an area of 6600 m2 of soybean, with 60 plots of 100 m2 each, with two sampling points/plot being evaluated weekly by the beat cloth method to count nymphs and adults. The evaluations occurred from fruiting (R3) to physiological maturation (R8). The data were subjected to dispersion indices (variance/mean ratio, Morisita index, and exponent k), theoretical frequency distributions (Poisson, negative binomial, and positive binomial), and spatial analysis by inverse distance weighting (IDW). This study demonstrated the infestation of E. heros throughout the evaluation period, and the dispersion indices showed the trend of nymph aggregation and the sum of nymphs and adults (total population). However, adults tended towards a moderate to uniform aggregation. Theoretical frequency distributions for nymphs and total population indicated randomness at the beginning of the infestation, tending to aggregation from R5 onwards. Aggregation is confirmed in adults, but the population tended towards uniformity at the end of the cycle. The use of the IDW method is an important tool for the rational management of the neotropical brown stink bug in the soybean crop. |

El presente trabajo tuvo como objetivo, estudiar la variación temporal y la distribución espacial de Euschistus heros (Hemiptera: Pentatomidae) en el cultivo de la soja. El trabajo se realizó en un área de 6000 m² de soja, con 60 parcelas de 100 m² cada una, siendo evaluados semanalmente dos puntos de muestreo/parcela por el método de paño de batida, contando ninfas y adultos. Las evaluaciones ocurrieron desde la fructificación (R3) hasta la maduración fisiológica (R8). Los datos fueron sometidos a los índices de dispersión (razón de varianza/media, Morisita y Exponente k) y distribuciones teóricas de frecuencias (Poisson, binomial negativa y binomial positiva), además del análisis espacial por Inverse Distance Weighting (IDW). Este estudio demostró la infestación de E. heros durante todo el período de evaluación, y los índices de dispersión demostraron la tendencia de agregación de ninfas y la suma de ninfas y adultos (población total), sin embargo, los adultos tendieron hacia una moderada agregación a la uniformidad. Las distribuciones teóricas de frecuencia para ninfas y la población total indicaron aleatoriedad al inicio de la infestación, con tendencia a la agregación a partir de R5. En los adultos se confirma la agregación, sin embargo, la población tendió a la uniformidad al final del ciclo. El uso del método IDW es una herramienta importante para un manejo racional de esta chinche en el cultivo de la soja.O percevejo marrom Euschistus heros (Hemiptera: Pentatomidae) é uma das mais importantes pragas em soja e o conhecimento da forma de distribuição deste inseto é necessário para determinar o momento de controle e possibilitar o uso apropriado das estratégias para evitar perdas na produção. O presente trabalho, objetivou estudar a variação temporal e a distribuição espacial de E. heros na cultura da soja. O trabalho foi conduzido em uma área de 6600 m2 de soja, com 60 parcelas de 100 m2 cada, sendo avaliada dois pontos amostrais/parcela semanalmente pelo método de pano de batida, contabilizando ninfas e adultos. As avaliações ocorreram a partir da frutificação (R3) até a maturação fisiológica (R8). Os dados foram submetidos aos índices de dispersão (razão variância/média, Morisita e Expoente k) e distribuições teóricas de frequências (Poisson, binomial negativa e binomial positiva), além da análise espacial por Inverse Distance Weight (IDW). Este estudo demonstrou a infestação de E. heros durante todo o período de avaliação, e os índices de dispersão demonstraram a tendência de agregação de ninfas e o somatório de ninfas e adultos (total da população), contudo, os adultos tenderam de uma moderada agregação à uniformidade. As distribuições teóricas de frequência para ninfas e total da população indicaram aleatoriedade no início da infestação tendendo a agregação a partir de R5.
