Soybean resistance to stink bugs [Nezara viridula and Piezodorus guildinii] increases with exposure to solar UV-B radiation and correlates with isoflavonoid content in pods under field conditions
Solar UV-B radiation [280-315nm] has a significant influence on trophic relationships in natural and managed ecosystems, affecting plant-insect interactions. We explored the effects of ambient UV-B radiation on the levels of herbivory by stink bugs [Nezara viridula and Piezodorus guildinii] in field...

| 520 | |a Solar UV-B radiation [280-315nm] has a significant influence on trophic relationships in natural and managed ecosystems, affecting plant-insect interactions. We explored the effects of ambient UV-B radiation on the levels of herbivory by stink bugs [Nezara viridula and Piezodorus guildinii] in field-grown soybean crops. The experiments included two levels of UV-B radiation [ambient and attenuated UV-B] and four soybean cultivars known to differ in their content of soluble leaf phenolics. Ambient UV-B radiation increased the accumulation of the isoflavonoids daidzin and genistin in the pods of all cultivars. Soybean crops grown under attenuated UV-B had higher numbers of unfilled pods and damaged seeds than crops grown under ambient UV-B radiation. Binary choice experiments with soybean branches demonstrated that stink bugs preferred branches of the attenuated UV-B treatment. We found a positive correlation between percentage of undamaged seeds and the contents of daidzin and genistin in pods. Our results suggest that constitutive and UV-B-induced isoflavonoids increase plant resistance to stink bugs under field conditions. | ||
