Aphids can cause deformation, wilting and defoliation of new growth of blueberry plants. High infestations can reduce fruiting bud formation for the following year's crop. Aphids produce copious amounts of honeydew and can cause secondary pest outbreaks of sooty molds on foliage and fruit. Aphids also can transmit blueberry scorch virus.
