Abstract

Halyomorphahalys(Stål) is a severe agricultural pest that is spreading worldwide from its original distribution in Asia. Egg parasitoids from Asia, which play a key role in the population dynamics ofH.halys, are following its host along global pathways. We present the first records ofTrissolcusmitsukuriiin Europe, and ofTrissolcusjaponicusin Italy. Both discoveries were made in northern Italy, whereH.halysis widely present and has reached extremely high population densities in some areas. Given the availability of their host, the distributions and populations of these exotic egg parasitoids are expected to expand, even in the absence of human intervention.
