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 ... -
Heptyl butyrate, a putative pheromone involved in social communication of Vespula germanica wasps
(2018-02)Greater knowledge on the social communication of invasive Vespula germanica wasps is needed to fully understand their foraging behavior. This is particularly valuable considering that poison baiting is currently the only ... -
Honeydew production by the giant willow aphid (Tuberolachnus salignus, Hemiptera: Aphididae) and its effect on foraging yellowjackets (Hymenoptera: Vespidae)
(Wiley, 2023-08)BACKGROUND: Understanding the factors that promote the success of invasive species is important for managing biological invasions. Interactions between invasives and other species (e.g. competitors, pathogens, or predators), ... -
Host-related volatile cues used by a parasitoid wasp during foraging for its woodboring host
(Wiley, 2018-12)Parasitoids relymainly on infochemicals to search for their herbivore hosts to oviposit on. Megarhyssa nortoni (Cresson) (Hymenoptera: Ichneumonidae) is a parasitoid of siricid wasp larvae which are concealed inside tree ... -
Insectos de importancia económica y sanitaria : “Avispas barrenadoras de la madera: Sirícidos invasores en la Patagonia”
(EEA Bariloche, 2020-08)Durante las últimas tres décadas han sido introducidas accidentalmente en la región patagónica tres especies de avispas barrenadoras de la madera. Su gran potencial invasor e impactos sobre la actividad forestal han llevado ... -
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 ... -
Managing nuisance social insects in urban environments : an overview
(2017-04)Urbanization is progressing worldwide where social insects often attain pest status. We present an overview of the practices applied for the management of social insects in urban settings from 1990 to 2016. We found that ... -
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 ... -
No evidence of enemy release in pathogen and microbial communities of comnon wasps [Vespula vulgaris] in their native and introduced range
(2015-03-23)When invasive species move to new environments they typically experience population bottlenecks that limit the probability that pathogens and parasites are also moved. The invasive species may thus be released from biotic ... -
Nueva avispa invasora en Chile : El Avispón Oriental, Vespa orientalis ¿Llegará a la Argentina? ¡Estaremos atento!
(EEA Bariloche, INTA, 2020-12)Una nueva avispa social invasora, conocida como “Avispón Oriental”, fue detectada recientemente en el centro de Chile (Región Metropolitana). Si bien este hallazgo no implica necesariamente que llegue a la Argentina, estar ... -
Of volcanoes and insects: the impact of the Puyehue–Cordon Caulle ash fall on populations of invasive social wasps, Vespula spp.
(2013-03)Las erupciones volcánicas tienen importantes efectos en los ecosistemas terrestres. Los efectos bióticos de ceniza volcánica en las poblaciones de insectos varian de un generalizado y catastróficoa lo sutil y localizada. ... -
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 ... -
Pest management of social insects in urban settings
(2017-04)Pest management of social insects in urban environments is a growing global concern, given the problems that these pests generate and the growth of urban areas worldwide. In this special issue, we present studies on the ... -
Polistes dominula (Hymenoptera: Vespidae) paper wasps detect native grasshoppers using olfactory cues
(Wiley, 2023-10)Polistes dominula is an invasive social wasp that preys on the grasshopper Dichroplus elongatus, which constitutes a potential agricultural pest in Northwest Patagonia. This grasshopper feeds on a wide variety of plants, ... -
Polistes dominula, “falsa chaqueta amarilla” : la avispa de papel presente en la Patagonia Argentina
(Ediciones INTA, 2018-12)Polistes dominula es una especie invasora exitosa, que ha mostrado tener efectos ambientales y económicos negativos en diferentes partes del mundo, sumado a su poderosa picadura. Desde el año 2003 esta especie está presente ... -
