Relationship between stink bug populations and soybean (Glycine max L.) phenology
International Journal of Tropical Insect Science 41 (1), 225-229
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 collected from 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 reproductive 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 number of collected insects was positively related between reproductive soybean phonological stages, suggesting that stink bugs population can compromise crop production.
