The marbled brown heron, Halyomorpha halys Stål has been in Catalonia for seven years, and since then, it has spread through the four Catalan provinces. During this time it has caused damage to some crops. Nevertheless, thanks to the increase in the knowledge of the biology of the plague in our conditions, it is possible to avoid serious damage.
