The leek moth (LM) is a recent invasive pest occurring within Northern NY and Vermont. A pest of onions and garlic, LM is a serious threat to diversified farms in the region. Recent ecological simulations predict that “the continued range expansion of LM…appears to be inevitable”. Our monitoring program will monitor the LM’s known and potential distribution. The objective of the monitoring program will be to describe the current distribution of the pest and to assess its local phenology.
