Join Holden Arboretum’s Natural Areas Biologist Rebecah Troutman to learn more about a newly discovered enemy of the invasive garlic mustard. This webinar will teach participants how to find and identify Liaphis alliariae, a garlic mustard specialist aphid native to Europe. This aphid was found during the 2021 field season. Affected plants produced twisted seed pods and puckered/wilted leaves. Given the importance of controlling garlic mustard, the novel nature of the newly discovered aphid in the United States, we are trying to better understand the impact this species has on garlic mustard- could it be a desperately needed biocontrol agent? The objective is to quantify the impact of this novel aphid on garlic mustard and map its current distribution.
