Last week (6-8-13) the first emergence of the adult red-headed flea beetle (Systena frontalis) was observed in a Cumberland County nursery. This insect has been a major pest at numerous NJ nurseries during the past several years. Primarily a concern with container crops in nurseries, it has an extensive host range. The foliage damage to plants from this 0.2-0.25 inch adult beetle can become extreme.
