Abstract On behalf of Koppert Biological Systems, a desk study has been carried out on effects of diffuse greenhouse coverings and coverings with a different light spectrum on pollination and seed setting in tomatoes. The information in the literature was found to be limited. Under diffuse glass, production increases by bigger and sometimes more fruits, but it is unknown whether this is partly due to a better seed setting. Red and pearl netting above the crop does increase production. Yellow and pearl nets reduce the virus attack by less activity and rejection of harmful insects. Higher UV-light absorption increases the protection against harmful insects, but may reduce the search behavior of predators and bumblebees
