Intentionally translocated species mostly have very re- stricted food preference. The chances that they become a problem as a result of feeding on non-target species is lowest in monophagous species. We analysed the food preference of the unintentionally translocated species. In Figure 3 the number of species is presented for the next groups of phytophages: monophages - species that de- velop on a single plant species or genus; oligophages - species that develop on more than one plant genus of a single plant family; polyphages - species that develop on plant species of more than one family. It shows that most of these successful translocated species are mono- or oligophagous; they develop on plant species within a single genus or within a single plant family. This more or less implies that, because of the food restriction of most leaf beetles, host plants from the same genus or family have to be avail
