Michigan State University Researchers Address Spread of Invasive Lily Leaf Beetle
The lily leaf beetle, an invasive species originally from Eurasia, is spreading across Michigan, prompting scientists at Michigan State University (MSU) to seek public assistance in tracking its presence. Known for feeding on the leaves, stems, and flowers of lily plants, the beetle poses a significant threat to plants in the Lilium and Fritillaria families. The beetle was first detected in North America in the 1940s and entered the United States in 1992, rapidly spreading across New England. Michigan's first confirmed detection occurred in 2016 in Jackson County, and by 2022, it had spread significantly across Southeast Michigan. MSU scientists are studying the beetle's spread and exploring a biological control program that has been effective on the East Coast. This program involves using a small parasitoid insect that targets the beetle's larvae, potentially reducing its population.
