Biological control is introducing a naturally occurring predator to a pest. Here at SCWP, we use flea beetles (Aphthona lacertosa and Aphthona nigriscutis) in order to treat Leafy spurge infestations throughout the county. In late spring, the adults emerge and feed on the plant's leaf tissue. Almost immediately the females start laying eggs at the soil near the stem base. When the larva hatch, they begin feeding on the root system, severely weakening the Spurge. This type of weed management is especially important in hard-to-reach areas where spray equipment is not feasible.
Other weed-control insects are available for the following species:
