Author Biography

Roy Van Driesche, University of Massachusetts, is an expert in biological control in the Entomology Division of the University of Massachusetts at Amherst. An earlier book on this topic by Van Driesche was published in 1996 as well as one on the invasive species problem. He is currently working to resolve the threat to eastern hemlock (a native forest tree) posed by an invasive Japanese adelgid.

Mark Hoddle, University of California, Riverside, has written numerous articles and edited conference proceedings on biocontrol. He has recently successfully controlled the glassy wing sharpshooter in French Polynesia with introduced egg parasitoids.

Ted Center, US Department of Agriculture, Agriculture Research Service, is a world leader in biological control of invasive plants, in particular against the world's worst water weed, waterhyacinth, and against melaleuca, an invasive Australian tree threatening the survival of the Florida Everglades, a World Heritage site.
