Edited by Italy's leading experts on the subject, this publication brings together all the information currently available on the Asian hornet, or Vespa velutina, and is intended to be a kind of emergency manual "for environmental resistance against the Asian invader," in defense of the complex ecological system that forms the Italian peninsula. It is addressed primarily to beekeepers, but also to all citizens who, unable to stand idly by, want to understandand try to take action against a threat that could have very serious repercussions for our entire ecosystem.From an editorial point of view, this is a small gamble that, in agreement with the authors, we have gladly accepted, with the hope of offering one more tool (and in our own way), filling a gap in the printed paper.
