Japanese beetles are a highly invasive species of beetle native to Japan, as their name suggests. They were first discovered in the United States in 1916, having likely been introduced accidentally through imported plant material. Since then, they have become a significant pest in many parts of Minnesota.
Japanese beetles are known for their distinctive metallic green bodies with coppery-brown wing covers. These beetles feed on a wide variety of plants, both as adults and as larvae. As larvae, they are known as white grubs and live in the soil, feeding on grassroots, which can cause damage to lawns and agricultural crops. As adults, they feed on the foliage, flowers, and fruits of over 300 different plant species.
Their feeding behavior can cause significant damage to plants, including skeletonizing leaves, defoliation, and ultimately weakening or killing the plant if infestations are severe enough.
Controlling Japanese beetles can be challenging, as they have few natural predators in Minnesota and are highly mobile, capable of flying several miles in search of food and suitable egg-laying sites. Various methods are used to control Japanese beetles, including chemical pesticides, biological controls (such as predatory insects or pathogens), and cultural practices like handpicking beetles off plants.
