The greenhouse whitefly (Trialeurodes vaporariorum) is a typical greenhouse pest that affects many crops.
Sciarid flies are small, black insects (3-5 mm) with slender antennae and long legs. Especially the larvae cause a lot of damage.
Adult thrips are small, elongated insects with typical fringed wings. They measure about 1 mm, and have a greyish or yellow to brown colour. The two most common harmful species are the onion thrips (Thrips tabaci) and the western flower thrips (Frankliniella occidentalis).
