The yellow-legged hornet, Vespa velutina nigrithorax is an Invasive Alien Species introduced into Europe in 2004, and is currently present in France, Italy, Spain, Portugal, Germany, and Belgium. It was also recently introduced in the United Kingdom and Switzerland. Here we present the first detection of V. velutina in the westernmost Mediterranean islands (Majorca, Balearic archipelago). In

Vespa crabro Linnaeus. Vespa crabro (Hornet) is a species of Hymenoptera in the family Vespidae. They visit flowers of English ivy, coastal sweetpepperbush, rockspray cotoneaster, and Giant Angelic. They are diurnal. Individuals can grow to 25 mm. Saccharomyces cerevisiae (Desm.) Meyen 1838 (baker's yeast)

The European hornet Vespa crabro L. (Hymenoptera: Aculeata: Vespidae) is considered the largest native vespid wasp in Europe. The females use their sting to defend themselves and the colony.

Vespula germanica. Los véspidos ( Vespidae) son una familia de insectos himenópteros apócritos, cosmopolita y diversa (alrededor de 5000 especies) que incluye a casi todas las avispas eusociales conocidas, así como muchas avispas solitarias. Se distinguen de otras familias cercanas, a veces también denominadas de manera genérica avispas

Vespoidea. Los vespoideos ( Vespoidea) son una superfamilia de insectos del orden Hymenoptera; en antiguos esquemas taxonómicos varía en esta categorización, particularmente en su reconocimiento de la superfamilia Scolioidea, ahora obsoleta. Los miembros más conocidos de este grupo son avispas y hormigas .

The yellow-legged hornet, Vespa velutina, is a recent invasive species in Galicia (NW Spain). Its invasion has an important socio-economic impact because it preys upon honeybees (Apis mellifera) and other crucial insect pollinators. The dispersal of this species must be monitored to minimise the damage it causes and to take the necessary control actions. The aims of this study were to Vespa crabro is a social species that displays a caste polymorphism. The fertile females, called queens, are 3,5 to 5 cm long, the sterile females (workers) and the males measure about 3 cm. The main morphological and chromatic characteristics of the species can thus be summarized. The head is big, of brown yellowish colour; the clipeus 5. This laboratory study provides a first assessment under controlled conditions of the factors affecting competition between workers of two hornet species and proposes a framework to assess, in wild contexts, the magnitude of the competition and the impact of the introduced V. velutina on the native V. crabro.

In the last checklist of Korean Vespidae, eight species of Vespa have been listed (Choi et al., 2013) and the only key to Korean Vespa species (Kim et al., 2006) is out of date. The world key to 23 Vespa species was provided by Archer (1989) and later was updated by Archer (2012) after V. auraria and V. velutina were synonymized.

The Vespinae are a subfamily of social wasps in the family Vespidae. The group consists of four genera: Vespa (hornets, 22 known species), Provespa (nocturnal hornets, three species), and Dolichovespula and Vespula (yellowjackets, respectively 19 and 23 species) [ 1, 2 ]. Phylogenetic relationships among the four genera have been the subject of By Amber Bass, Karen Needham, & Andrew M R Bennett Zootaxa, 5154(3): 305-318, 2022 Cite: 2218564 with citation markup [cite:2218564] Social wasp venoms contain amines (histamine, tyramine, serotonin, and catecholamines), pep- tides, and proteins, including many hydrolases, 573 but quite different in nature from those in bee venom. The hornet Vespa crabro produces 19 mg of hydroxytryptamine per gram of venom sac. 574 Polyamines include putrescine, spermidine, and spermine. ^{Carisio et al.

We present a genome assembly from an individual female Vespa crabro (the European hornet; Arthropoda; Insecta; Hymenoptera; Vespidae). The genome sequence is 230 megabases in span. The majority of the assembly (94.93%) is scaffolded into 25 chromosomal pseudomolecules.

Low effective mating frequency in Vespa, in combination with data from other vespines, suggests that high paternity frequency is derived in the group, which is significantly biased with the majority male fathering on average 80% of the female offspring. Abstract Queen mating frequency was studied in the European hornet, Vespa crabro, by analyzing four DNA microsatellite loci in 20 workers from

Characteristics.-Vespa was introduced into the materia medica by Hering. The symptoms of the Schema Are mostly the results of stings. Berridge proved Vesp. crabro 30 on three persons. Low spirits; pain in right ear; nausea with faint feeling and trembling; pain in left side of the neck on waking-these were the chief symptoms experienced by them
