Mealy Bugs

Both the Vine mealybug (Planococcus ficus) and Grape mealybug (Pseudococcus maritimus) are small, cryptic insects that infest all parts of the vine and produce large amounts of honeydew (clear, sugary excretions) that damage the fruit and foliage, resulting in unmarketable grapes. The mealybugs also cause the grapevine to decline in vigour and production, as well as transmitting grapevine viruses.
