Damage symptoms The yellow rose aphids usually live in young unfolded [...] and adults extract nutrients from the plant and disturb the balance of growth hormones. As a result, the plant’s growth is retarded giving rise to deformed [...] ornamental crops. At the same time, photosynthesis in the leaves is reduced, affecting production. The yellow rose aphid is also a vector of several viruses

  damage is the immediate result of larvae feeding on the roots. The larvae feed mainly on decaying plant material and on algae and fungi present in the soil [...] Pupation takes place in a small hole in the ground. Pupae are white, but later become yellow to brown. The posterior end of the pupa remains mobile.

Plant sap is rich in sugars, but [...] secretion of the mealybugs, reduces the ornamental value of the affected plants. Fruit and flowers are also fouled, rendering them unfit for sale, and the reduced [...] reduced level of photosynthesis in the leaves also reduces flower and fruit production.
