Due to their size, thrips are difficult to recognize. One can recognize an infestation however very well by the damage pattern. Thrips suck out the outer leaf cells with their proboscis, leaving silvery, white spots on the upper leaf surfaces and the flowers, which can later turn brown. This can lead to deformations in young leaves and heavily infested leaves die off. The damage pattern of thrips is similar to that of spider mites. The difference is, however, that spider mites form threads and, unlike thrips, have a rounded body.
Thrips lay between 60 and 70 eggs, from which a reproductive generation has developed after 4 weeks. The so-called fringe-wingers like it dry and therefore occur above all in apartments and greenhouses. Since they are so small, they are easily carried by the wind to other plants.
As soon as thrips are visible on the plants or blue and yellow panels show the first catches, the affected plants should be isolated.
