Invasive plants present a major ecological concern, and their successful management is vital for the sustenance of ecosystem integrity and biodiversity. Alliaria petiolata (garlic mustard) invades deciduous forests in North America with few natural threats from herbivores. Biological controls, however, might be an effective and environmentally sound way to eradicate garlic mustard populations. Simulated herbivory is a suitable way to experimentally study the effects of herbivory on plant growth and reproduction. After simulating herbivory on garlic mustard plants, we found that our treatments had no effect on the plants’ growth or reproduction. If ecologists plan to utilize biological controls, these herbivores must inflict a large amount of damage to produce an effect on garlic mustard. Due to its resilience against herbivory, this plant deserves a great deal of attention and might require more swift means of eradication than herbivory.
