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 ... -
Determining the origin of invasions and demonstrating a lack of enemy release from microsporidian pathogens in the common wasps (Vespula vulgaris)
(2014-08)La comprensión del papel de la liberación de enemigo en las invasiones biológicas requiere una evaluación del área de distribución del invasor, el número de eventos de invasión y la prevalencia del enemigo. La avispa común ... -
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 ... -
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 ...
