This small black beetle has been used to control and eradicate almost every whitefly species of commercial importance, from the “Giant” whitefly on Eucalyptus in California, to Bemisia in Poinsettia. It is native to Florida where its’ natural host is, Bemisia. Because of this, Delphastus will seek out and destroy any Bemisia colonies before it moves on to other species of whitefly.
• Cloudywinged, citrus and rhododendron whitefly (Dialeurodes spp.)
• Citrus blackfly (Aleurocanthus woglumi)
