Abstract：
BACKGROUND: Soybean is the third-greatest global commodity crop with respect to grain production, Brazil is the largest soybean producer in the world. We performed the first extensive survey including all the five main soybean cultivation regions in Brazil over three seasons (2018/2019, 2019/2020, and 2020/2021). A total of 2386 localities were sampled, corresponding to 145 municipalities in 11 states. Sampling was carried out between the R1 and R8 soybean growth stages, using a beating sheet.
RESULTS: Fifteen species were recorded, with five species accounting for more than 99% of the sampled insects. The Neotropical brown stink bug, Euschistus heros (F.), was the most abundant species (82.4% of the adults and 84.1% of the nymphs overall), with differences in the mean abundance between soybean macroregions. The melacanthus green belly stink bug, Diceraeus melacanthus Dallas was the second most abundant species overall, followed by the brown winged stink bug, Edessa meditabunda (F.), the furcatus green belly stink bug, Diceraeus furcatus (F.) and the red-banded green stink bug, Piezodorus guildinii (Westwood). The relative abundance of each species differed between soybean macroregions. The mean abundance of nymphs and adults of Euschistus heros at different soybean reproductive stages showed an increase from early reproductive stages to the beginning of the late reproductive stages (R5 or R6).
CONCLUSIONS: This large-scale assessment of stink bugs provides a basis for outlining integrated pest management programs and drives the development of monitoring and control strategies, as well as future studies investigating population dynamics over time and space in soybean fields. © 2024 Society of Chemical Industry.

摘要：
背景：就谷物生产而言，大豆是全球第三大商品作物，巴西是世界上最大的大豆生产国。我们进行了首次广泛调查，包括巴西三个季节（2018/19、2019/20和2020/21）的所有五个主要大豆种植区域。共抽取了2386个地方,相当于11个州的145个城市。在R1和R8大豆生长阶段之间进行采样，使用跳动的床单。
结果：记录了15种，其中5种昆虫占采样昆虫的99%以上。新热带棕色臭虫，Euschistus英雄（F.),是最丰富的物种(82.4%的成虫和84.1%的若虫)，大豆大区域之间的平均丰度存在差异。黑瓜绿色的腹部臭虫，DiceraeusmelacanthusDallas是总体上第二丰富的物种，接着是棕色翅膀的臭虫，Edessameditabunda(F.),furcatus绿色的腹部臭虫，双对虾(F.)和红色条带的绿色臭虫，Piezodorusguidinii（韦斯特伍德）。大豆大区域之间每个物种的相对丰度不同。在不同的大豆生殖阶段，若虫和E.heros成虫的平均丰度从生殖早期到生殖后期（R5或R6）开始增加。
结论：这种对臭虫的大规模评估为概述病虫害综合管理计划提供了基础，并推动了监测和控制策略的制定，以及未来研究大豆田中种群随时间和空间的动态。本文受版权保护。保留所有权利。
