Abstract To develop a practical integrated pest management (IPM) system for the multicolored Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), in wine grapes, we assessed the spatial distribution ofH. axyridis and developed eight sampling plans to estimate adult density or infestation level in grape clusters. We used 49 data sets collected from commercial vineyards in

The Asian longhorned beetle (Anoplophora glabripennis), also known as the starry sky, sky beetle, or ALB, is native to eastern China, Japan, and Korea. This species has now been accidentally introduced into the United States, where it was first discovered in 1996, as well as Canada, and several countries in Europe, including Austria, France, Germany, Italy and UK.
