Nysius cymoides (Spinola, 1837)
This species of false chinch bugs is found in southern and central parts of Europe, the Mediterranean region and parts of western Asia. Like most other Nysius species, it is polyphagous, but appears to have a preference for Brassica species. Damage on crops like sunflower or soybeans have been also reported.
There have been several outbreaks in the Mediterranean region. For example, in Italy during 2017, a serious outbreak occurred on soybean, planted directly after canola. During that outbreak up to 250 bugs were recorded per plant, resulting in necrosis, wilting and often plant death (Scaccini & Furlan, 2019).
Adult bugs are 3½ to 4 mm long, with a mottled brownish/greyish colouration. Typically, there is one generation per year, with the adults being the overwintering stage.
