Brewer’s yeast, Saccharomyces cerevisiae, enhances attraction of two invasive yellowjackets (Hymenoptera: Vespidae) to dried fruit and fruit powder
(2017-09)The German yellowjacket, Vespula germanica F., and common yellowjacket, Vespula vulgaris L. (Hymenoptera: Vespidae), are pests of significant economic, environmental, and medical importance in many countries. There is a ... -
Conducta de recolección de alimento en Vespula Germanica: Implicancias para el control de avispas sociales invasoras en la Patagonia
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2019)Durante la búsqueda de alimentos los individuos necesitan resolver si explotar un recurso dado o continuar buscando nuevos sitios de alimentación, que posiblemente sean mejores. Esta decisión se basa principalmente en la ... -
Dinámica de la dispersión y actividad de la avispa exótica Vespula germanica F. (Hymenoptera: Vespidae) en Argentina
(Centro Regional Universitario Bariloche, Universidad Nacional del Comahue, 2013)Las invasiones biológicas son un tema central de la ecología. Por un lado, la introducción de especies exóticas brinda un excelente escenario para estudiar procesos demográficos y las interacciones sobre la estructura de ... -
Dispersal behavior of yellowjacket (Vespula germanica) queens
(2018-02)Understanding the factors that affect animal dispersal behavior is important from both fundamental and applied perspectives. Dispersal can have clear evolutionary and ecological consequences, but for nonnative insect pests, ... -
Field preferences of the Social Wasp Vespula germanica (Hymenoptera: Vespide) for Protein-rich Baits
(2013-09)Las preferencias alimentarias mostrados por forrajeo insectos son importantes desde una perspectiva fundamental y en el control de plagas. Se estudió la preferencia de un invasiva avispa, V. germanica, de alimentos ricos ... -
Flexible foraging decisions made by workers of the social wasp Vespula germanica (Hymenoptera: Vespidae) in response to different resources: influence of ontogenetic shifts and colony feedback
(Wiley, 2022-04)Decisions made by foraging animals conform a complex process based on the integration of information from multiple external environmental stimuli and internal physiological signals, which in turn are modulated by individual ... -
Gustatory responsiveness in Vespula germanica workers: exploring the interplay between sensory perception and task specialization
(Wiley, 2023-08-03)Workers’ task specialization and division of labor are critical features of social insects’ ecological success. It has been proposed that the division of labor relies on response threshold models: individuals varying their ... -
Long-term coexistence of two invasive vespid wasps in NW Patagonia (Argentina)
(Springer, 2022-07-03)In Patagonia (Argentina) two non-native vespid wasps became established in the last decades. Vespula germanica was first detected in 1980, while V. vulgaris arrived some 30 years later. Both species can have a strong ... -
Nest-departure behaviour of gynes and drones in the invasive yellowjacket Vespula germanica (Hymenoptera: Vespidae)
(Cambridge University Press, 2020-08)Inbreeding costs can be high in haplodiploid hymenopterans due to their particular mechanism of sex determination (i.e., single-locus complementary sex-determination system, sl-CSD), as it can lead to the production of ... -
Perspectivas de estrategias para el manejo de la Chaqueta Amarilla
(EEA Bariloche, INTA, 2021-12)Las avispas “chaqueta amarilla” se encuentran bien establecidas en la Patagonia Argentina. Cada verano, cuando la abundancia de estas avispas comienza a ser alta, muchas actividades cotidianas al aire libre se ven afectadas ... -
Sugar responsiveness could determine foraging patterns in yellowjackets
(Nature, 2023-11)Sympatric-related species often exhibit resource partitioning. This can occur through diferent mechanisms, such as behavioral, morphological, and sensory variations, leading to qualitative, temporal, or spatial diferences ... -
The origins of global invasions of the German wasp (Vespula germanica) and its infection with four honey bee viruses
(Springer, 2018-12)A successful control or eradication programme using biological control or genetically-mediated methods requires knowledge of the origin and the extent of wasp genetic diversity. Mitochondrial DNA variation in the native ...
