Are invasive species promoting yellowjacket invasion in Patagonia?
(Wiley, 2022-06)In recent decades, yellowjacket wasps, including Vespula vulgaris, have successfully been established in Patagonia. Additionally, the invasive willow Salix fragilis has also invaded areas next to watercourses, which in ... -
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 ... -
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 ... -
A comparative analysis of host feeding and life-history traits in parasitoid wasps
(2016-05)Feeding in insect parasitoids can have significant implications from behavioral and evolutionary ecology standpoints. Females of many species not only search for hosts to lay their eggs on, but also may use them as a food ... -
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 ... -
Ecological effects and management of invasive alien Vespidae
(Springer, 2011-08)Insect species associated with human goods continue to be accidentally introduced into new locations. A small proportion of these introduced species become invasive, causing a range of impacts in the receiving community. ... -
Factors affecting success of galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) = Factores que afectan el éxito de las agallas de Aditrochus coihuensis (Hymenoptera: Pteromalidae)
(Sociedad Entomológica Argentina, 2011-12)Galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) were collected from their host tree, the southern beech Nothofagus dombeyi, near San Carlos de Bariloche, Argentina, during the spring of 2007. Galls were carefully ... -
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 ... -
Flight capabilities of invasive yellowjacket Vespula germanica drones: the effect of kinship and nutrition
(Wiley, 2024-01)Dispersal is a multifactorial process which may influence, among several others, population dynamics, inbreeding likelihood, and mate competition. For species that disperse by flight, many studies have suggested that ... -
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 ... -
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 ... -
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 ... -
