Article: "Assessment of the In Vivo and In Vitro Release of Chemical Compounds from Vespa velutina"

Vespa velutina 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 communication and they could be used an integrated pest management tool alternative to conventional pesticides. A previous determination of the organic chemical profile should be the first step in the study of these semiochemicals. HS-SPME in living individuals and the sting apparatus extraction followed by GC-MS spectrometry were combined to extract a possible profile of these compounds in 43 hornets from Galicia. The identified compounds were hydrocarbons, ketones, terpenes, and fatty acid, and fatty acid esters. Nonanal aldehyde appeared in important concentrations in living individuals. While pentadecane, 8-hexyl- and ethyl oleate were mainly extracted from the venom apparatus. Ketones 2-nonanone, 2-undecanone and 7-nonen-2-one, 4,8-dimethyl- were identified by both procedures, as was 1,7-Nonadiene, 4,8-dimethyl-. Some compounds were detected for the first time in V. velutina such as naphthalene, 1,6-dimethyl-4-(1-methylethyl). The chemical profile by caste was also characterized.

New Research Study "Vespa velutina: características e impactos de una exitosa especie exótica invasora"

Vespa velutina: traits and impacts of a successful invasive alien species

The invasion of Vespa velutina Lepeletier, 1836 continues to expand into new areas. It is an invasive alien species that currently produces
social alarm and concern for its ecological, economic and social impacts. The objective of this work is to explore the biological traits of the species to
understand the reasons for its invasive success and impacts. These are related to aspects such as a complex social system, a versatile generalist behaviour
or a high reproductive rate added to its ability to establish colonies from a single mated queen. The impacts of this hymenopteran on ecosystems
and beekeeping are related to its behaviour as a predator of insect-pollinators, particularly honeybees. The increase of the population during summer
and its preference for urban and semi-urban areas entail frequent encounters with people, resulting in an increased risk of being stung. Its defences
involve chemical communication triggering collective attacks and the injection of a venom rich in toxins that impacts human health.
