What is the scientific name of the Grape Mealybug?

The Grape Mealybug is scientifically identified as Pseudococcus maritimus. This species is known for infesting grapevines and can cause significant damage to grape crops through its feeding, as it extracts sap and can also lead to sooty mold growth.

The other options refer to different species not associated with the grape mealybug. Pseudococcus viburni is known as the viburnum mealybug, affecting various plants but not specifically grapes. Amyelois transitella is the scientific name for the navel orangeworm, which is a pest of stone fruits, and Anarsia lineatella refers to the peach twig borer, another pest that targets specific fruit crops but not grapes. Thus, the specificity of Pseudococcus maritimus to grapevines makes it the correct identification for Grape Mealybug.
