Avispas exóticas en la Patagonia: la importancia de la ecología de invasiones en el manejo de plagas
(2014-08)El manejo integrado de plagas (MIP) se basa en el conocimiento de la ecología de las especies problema. Se ha sugerido que cuando las plagas son especies invasoras, la comprensión del proceso de invasión puede mejorar aun ... -
Balance fitosanitario: plagas de relevancia temporada 2022-23
(EEA Alto Valle, INTA, 2023)La temporada 2022/23 se caracterizó por un conjunto de condiciones climáticas que orientó la presencia y abundancia de determinadas plagas. A continuación, se detallan las plagas que estuvieron presentes, pero con una ... -
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 ... -
Chaqueta amarilla : biología, monitoreo y control de la avispa Vespula germanica en el Alto Valle de Río Negro y Neuquén
(EEA Alto Valle, 2013)La especie Vespula germanica (Fabricius, 1793) conocida vulgarmente como "chaqueta amarilla" es un insecto de hábitos sociales originario de Eurasia y el norte de África, colonizó numerosos lugares del mundo incluido nuestro ... -
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 ... -
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, ... -
Distribution, dispersal and spread of the invasive social wasp (Vespula germanica) in Argentina
(2013-04)Se estudió la distribución y difusión de la avispa invasora sociales Vespula germanica en Argentina, se centra en la contribución de la dispersión de la reina de la expansión territorial. Vespula germanica es originaria ... -
Drone aggregation behavior in the social wasp Vespula germanica (Hymenoptera: Vespidae): Effect of kinship and density
(Nature Research, 2020-04)Inbreeding can have negative consequences on population viability because of the reduced fitness of the progeny. In general, most species have developed mechanisms to minimize inbreeding such as dispersal and kin avoidance ... -
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 ... -
Foraging behavior interactions between two non-native social wasps, Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) : implications for invasion success?
(2016-01)Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded – 35 yrs earlier – by another wasp, Vespula germanica. Although V. vulgaris ... -
Foraging niche separation of social wasps in an invaded area: Implications for their management
(Wiley Online Library, 2019-10)Foraging niche separation may be a mechanism to promote coexistence of two competing species by concentrating intraspecific competition relative to interspecific competition. The present study investigated foraging behaviour ... -
Local dynamics of worker activity of the invasive Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) wasps in Argentina
(2016-02)1. The abundance of insects depends essentially on the reproductive success of individuals. In social insects, however, the abundance of sterile workers outside a nest depends on colony size but is also determined by ... -
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 ... -
Mate-searching behavior in the invasive German wasp, Vespula germanica, in Patagonia
(John Wiley & Sons Ltd, 2018-07)In order to increase the probability of reproduction, social insects can adopt various mate‐finding strategies, such as increasing densities of males at specific locations, and/or visual and chemical cues that attract the ... -
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 ... -
