Abstract The populations of phytophagous stink bugs may vary with cultivar and crop management. The aim of this study was to know the population dynamics of stink bugs Euschistus heros, Nezara viridula, and Piezodorus guildinii at different soybean phenological stages. Samples of each stink bug species were done in three soybean (Syn1059, P97R01, and M7110IPRO) cultivars conducted in two seasons. For three cultivars and two seasons, E. heros was the most abundant, followed by P. guildinii and N. viridula. The soybean phenology influenced stink bug population dynamics, mainly in the inflorescence emergence, flowering, development of fruits and seeds, and ripening of fruits and seeds stages. For soybean cultivars, Syn1059 and M7110IPRO were high colonized by stink bugs, while colonization in P97R01 was low suggesting susceptible differences between cultivars. The relationship between stink bug populations and soybean phenology can provide information to monitoring pest populations during these stages.

The soybean, Glycine max (L.) Merrill (Fabaceae) is a native plant from China and grown in large areas worldwide. Abiotic and biotic factors reduce soybean yield (Justiniano et al. 2014). Among biotic factors, stink bugs (Hemiptera: Pentatomidae) are phytophagous insects in soybean cultivars (Pan et al. 2013). Damages caused by stink bugs in soybean reduce seed yield and quality, low germination rate, foliar retention, delay in maturation and abnormal plant growth (Tuelher et al. 2016; Bentivenha et al. 2018; Mantia et al. 2018). The green bug, Nezara viridula Linnaeus, small green bug, Piezodorus guildinii Westwood and brown stink bug, Euschistus heros Fabricius are the main soybean pest (Bortolotto et al. 2015). Stink bug phytophagous are present in soybean crops during the principal gr
