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, a serious outbreak occurred in Italy during 2017 in soybean, planted directly after canola. During this 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. There is typically one generation per year, and the adult overwinters.
