In the context of possible biological control of Eurasian watermilfoil (Myriophyllum spicatum), available information is summarized on the distribution of M. spicatum and closely related species, and the known insect natural enemies recorded from Europe. Research gaps identified include (1) lack of adequate understanding of frequency, distribution and ecological differences resulting from hybridization between M. spicatum and other Myriophyllum spp., (2) that surveys to date have been limited geographically and temporally, and have neglected organisms attacking the roots, and (3) preliminary studies to date on potentially useful biological control agents have not considered potential impact on non target indigenous species. A phased programme to address these gaps is put forward.
