Abstract Vespula germanica (F.) is a social vespid that has invaded many parts of the world, including Argentina. This wasp usually becomes a pest, affecting several economic activities. It also may impact the host community through predation or competition. The purpose of our study was to field test toxic baiting for reduction of wasp abundance. Wasps were poisoned with 0.1% fipronil mixed with raw minced beef in two beech forest sites on 20 February 2000 in northwestern Patagonia. All nests… 

Control of Vespula germanica (Hym. Vespidae) populations using toxic baits: bait attractiveness and pesticide efficacy

It is shown that beef proved to be the most attractive bait tested, for Vespula germanica wasps in NW Patagonia, through field trials, and the use of hydramethylnon may allow the alternating of insecticides in specific situations.

Effective distances of wasp (Vespula vulgaris) poisoning using clustered bait stations in beech forest

Overall this baiting strategy did not produce the 80-90% average traffic reductions achieved by more intensive grid baiting systems, but suggests that spacing grouped bait stations approximately 250 m apart has the potential to reduce wasp densities to below an ecologically damaging level with considerably less effort.

The efficacy of Vespex® wasp bait to control Vespula species (Hymenoptera: Vespidae) in New Zealand

Transitioning from trials to pest control tool, the efficacy of controlling wasps Vespula vulgaris and V. germanica using Vespex® wasp bait was tested in 2015 and signals a future potential in the way that pest wasps might be managed in a community context for social, economic and biodiversity conservation objectives.

The effects of introduced vespid wasps (Vespula germanica and V. vulgaris) on threatened native butterfly (Oreixenica ptunarra) populations in Tasmania

An increase in the intensity of wasp control, in combination with other conservation management methods, is required for the protection and recovery of O. ptunarra without ongoing conservation measures, it is likely that butterfly numbers will stay low, potentially leading to genetic bottlenecks and more local extinctions.

Are invasive species promoting yellowjacket invasion in Patagonia?

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

Feeding strategies and intraspecific competition in German yellowjacket (Vespula germanica)

The results confirm the major role of the German yellowjacket as a scavenger, because its diet is based mostly on bee carrions, and reveal that intraspecific competition events increase when the resource is fresh (predation vs necrophagy), and that the number of competing wasps was significantly higher when the food consisted of pupae and drones, compared to adult bees.

Field preferences of the Social Wasp Vespula germanica (Hymenoptera: Vespidae) for Protein-rich Baits

The preference of an invasive wasp, V. germanica, for protein foods in field conditions is studied and it is suggested that food choice is a complex process subject to the influence of diverse factors.

Three non-toxic insect traps useful in trapping wasps enemies of honey bees

The results showed that the use of the wood-glue trap in combination with the fish as a bait was a reliable solution for controlling the wasps in apiaries.

Behavioural responses of Vespula germanica (Hymenoptera: Vespidae) wasps exposed to essential oils

A push–pull system combining attractive baits with the use of plant‐based repellents is a promising management strategy in urban settings for this insect pest.

Fresh meat baits are currently the only available effective option to detect low‐density Vespula germanica (Hymenoptera: Vespidae) populations in South Africa

The eusocial wasp Vespula germanica is a problematic invasive species in the Southern Hemisphere regions. Especially in New Zealand, Tasmania and Argentina, population densities can be very high and



Toxic baiting of the Western yellowjacket (Hymenoptera: Vespidae) in Hawaii.

Forager populations of the western yellow jacket, Vespula pensylvanica (Saussure), regularly declined in Hawaii in December despite the warm winter. This decline may be correlated with the


Individual wasps were about 16% heavier in the poisoned sites at the peak of the wasp season than in the non-poisoned sites, although this had a minimal effect on cumulative biomass over the entire season, and conservation gains need to be quantified.

Reduction of wasp (Hymenoptera : Vespidae) populations by poison-baiting; experimental use of sodium monofluoroacetate (1080) in canned sardine

Wasp numbers visiting bait stations containing non-toxic baits increased to about 30% of pre-poison levels 4 weeks after poisoning, but partially recovered at nests more than 100 m from baits.

Invasion success of the wasp parasitoid Sphecophaga vesparum vesparum (Curtis) in New Zealand

Abstract The wasp parasitoid Sphecophaga vesparum vesparum has been released in many parts of New Zealand since 1987 as a biological control agent for German (Vespula germanica) and common ( V.

Restructuring of Lepidoptera communities by introduced Vespula wasps in a New Zealand beech forest

Wasp abundance must be reduced by at least 88% to conserve the more vulnerable species of free-living caterpillars at wasp densities similar to those observed in the study sites, which equates to a damage threshold of 2.7 wasps per Malaise trap per day.

The impact of common and German wasps (Hymenoptera: Vespidae) on the New Zealand beekeeping industry

Overwintering nests were more common, and wasps caused more problems during spring buildup in the North Island than the South Island, relative to their population levels in the environment.

Reducing predation of orb‐web spiders by controlling common wasps (Vespula vulgaris) in a New Zealand beech forest

An experimental approach was used to test whether reducing the abundance of common wasps increases the probability of native invertebrates surviving and the level of wasp control necessary to protect natural populations of orb‐web spiders was estimated.

Seasonality of crane flies (Diptera: Tipulidae) in South Island beech forest in relation to the abundance of Vespula wasps (Hymenoptera: Vespidae)

The seasonality of adult crane fly species was determined by Malaise trapping so that species potentially vulnerable to an impact from high wasp numbers could be identified as possible indicator species for analyzing the wider impacts of wasps in beech forest (Nothofagus spp.) ecosystems.

Comparison of baits containing fipronil and sulfluramid for the control of Vespula wasps

Despite the low doses of fipronil needed to kill colonies, low bait attractiveness may limit the success of control operations using fipronsil in some situations.
