Save The Grapes! Enter The Mealybug Destroyer! | Deep Look | KQED
"If there ever was a bug that we should all raise a glass of wine for, it's the mealybug destroyer."
"This heroic bug has been brought in to protect grape vineyards from being ruined by the mealybugs sticky honeydew excrement."
"But first, the mealybug destroyer must get past the mealybugs' army of ant bodyguards who want that sweet honeydew excrement for themselves."
The mealybug destroyer is a beneficial insect introduced to vineyards to control mealybug infestations. Mealybugs secrete sticky honeydew excrement that can ruin grape vineyards by promoting sooty mold and damaging fruit. Ants protect and tend mealybugs to harvest that honeydew, forming a defensive barrier around mealybug colonies. The mealybug destroyer must bypass or overcome ant defenses to reach and reduce mealybug populations effectively. Managing ant activity or disrupting ant-mealybug interactions can improve the success of the biological control agent and the overall health of the vineyard.
