The 2016 season highlighted the need to protect crops from Halyomorpha halys, aka the brown marmorated stink bug. The main characteristics that make this insect particularly dangerous are: • considerable damage to crops, • quick transfers, • habitat on both forestry and agricultural        species, • lack of effective chemical products, • poor biological control results. "Field tests show that using nets as a physical barrier is currently the only viable option to obtain a reduction of the population up to 80-90%, in some cases even 99%," explains CEO Paolo Arrigoni. Choosing the right net is essential to obtain this results. All net characteristics must be taken into consideration i.e. warp-knitting, thread quality and the quantity of sunlight and air let through. These characteristics contribute to the degree of protection of the crop.
