Vitis rotundifolia Michx., commonly known as the muscadine, is a grapevine species native to the south-eastern and south-central regions of the United States. It remains the primary grape species in Florida with an estimated economic impact value of approximately $1 billion dollars . The grapevine aphid, Aphis illinoisensis Shimer (Hemiptera: Aphididae), is a key muscadine pest that feeds on young leaves and shoots thereby reducing the number of grapes produced. Additionally, this pest reduces yield by causing direct and indirect injury, including the potential to vector a variety of aphid borne viruses. A survey was conducted to determine the current population levels across major viticulture regions in Florida. The results of this survey serve as the cornerstone of an infographic that drives home the critically important role of Integrated Pest Management in the management of the grapevine aphid.
