Abstract: | While the accidental introduction of insect pests is becoming increasingly common due to intense and rapid commercial exchanges, the incidence of accidental introduction of their parasitoids seems to be much less frequent or is overlooked. The case reported here, for a tachinid Phasiinae, is both fortuitous and fortunate since the parasitoid has been carried from the New World by a pest that is already present in the new country, Italy, where there are virtually no competitors. Establishment and specificity of the parasitoid was confirmed by the first follow-up studies immediately after its discovery. |
