Pseudococcus viburni, also known as the viburnum aphid, is an aphid species belonging to the Pseudococcidae family. This small insect is often found in orchards, gardens, and greenhouses, where it can cause significant damage to host plants, particularly viburnum species and other woody plants.
Adult Pseudococcus viburni are small insects, generally measuring between 2 and 3 millimeters in length. Their body is usually oval and varies in color from light brown to dark brown. They have relatively short antennae and barely visible legs. Young nymphs may be lighter in color and more translucent in appearance.
Pseudococcus viburni reproduces parthenogenetically, which means females can produce eggs without requiring fertilization by a male. Young nymphs hatch from the eggs and quickly develop into reproductive adults, which can lead to a rapid increase in aphid populations under favorable conditions.
Viburnum aphids feed by piercing plant tissues with their piercing-sucking mouthparts. This can weaken host plants and lead to symptoms such as wilting, leaf deformation, premature leaf drop, and slowed growth. In addition, aphids secrete excess honeydew, a sticky sugary substance, which can promote the growth of sooty mold, a black fungus, on the leaves, thereby reducing the plant’s ability to photosynthesize.
Wearing gloves, place the pheromone in a special mealybug trap (delta trap type).
From the first captures, treat using a natural insecticide to eliminate eggs and larvae, or release green lacewings.
This pheromone can be stored for up to 2 years in the freezer. Once opened, you must use it. Results may vary from one period to another depending on the weather, the number of attacks, and the environment. The key is to understand that the pheromone trap and the pheromone are mainly used to detect moth flights, so you can treat at the right time, or not treat at all if there are no catches
