Scientists from the Agricultural Research Service have released a new biological control for the invasive melaleuca tree (Melaleuca quinquenervia) in southern Florida. The insect, Boreioglycaspis melaleucae, was chosen based on the damage it does to melaleuca in their native Australia. Scientists are hoping that the insects will work in concert with the melaleuca leaf weevil (also called the melaleuca snout beetle), Oxyops vitiosa, a biological control first introduced in 1997. You can read additional information about this project from the ARS here. There are several other biological control agents that have been introduced to help slow the spread of melaleuca.
