| description | Though rarely used in this way, biological control could potentially be exploited for managing spread of invasive species. Because spread of invasive species emerges from the combined action of population growth and dispersal, natural enemies that affect either of these processes should also affect spread. Dispersal of parasitoid species plays a key role in determining their impact on population growth of an invading host species along their expanding population front. In contrast, dispersal of most true parasites only occurs via movement of hosts so any impact that parasites may have on host dispersal may limit the parasite’s own capacity to keep up with an expanding host population. We test this premise by examining field data from what is probably the best example of the successful use of true parasites in biological control: the nematode Beddingia (=Deladenus) siricidicola, which is released for management of Sirex noctilio populations. We analyze the historical impact of nematode releases on the rate of spread of invasive S. noctilio populations in Southern Argentina. Our findings suggest that, nematode releases did not discernibly slow the spread of S. noctilio populations. We conclude that although entomophagous parasites could be effective at reducing the growth and dispersal of localized host populations, they are unlikely, unless widely released through the leading edges, to slow the spread of invading hosts |
