title: Extraction and physicochemical characterization of chitin derived from the Asian hornet, &lt;em&gt;Vespa velutina&lt;/em&gt; Lepeletier 1836 (Hym.: Vespidae)
abstract: The yellow-legged Asian hornet [Vespa velutina Lepeletier 1836 (Hymenoptera: Vespidae)] is naturally distributed in Southeast Asia, India, and China; however, fifteen years ago, at least one multimated female Asian hornet arrived in France. The species has subsequently expanded its range and is now presently recognized as a pan-European threat. In the present work, the isolation and characterization of chitin from Vespa velutina (VV) is described. Moreover, a trapping procedure is presented to s
