Assessment of the In Vivo and In Vitro Release of Chemical Compounds from <i>Vespa velutina</i>

<i>Vespa velutina</i> has been rapidly expanding throughout Galicia since 2012. It is causing human health risks and well-known losses in the beekeeping sector. Control methods are scarce, unspecific, and ineffective. Semiochemicals are insect-derived chemicals that play a role in commun...
