Social Wasps on Eugenia uniflora Linnaeus (Myrtaceae) Plants in the Urban Area of Viçosa, Minas Gerais State, Brazil

Sociobiology, 2013
Social wasps (Hymenoptera: Vespidae) of the subfamily Polistinae, being biological pest control agents, can effectively participate in ongoing efforts to limit the use of chemical agents used in combating insect pests in urban forestry.

Survey of social wasps (Hymenoptera, Vespidae, Polistinae) in Amazon rainforest fragments in Acre, Brazil [PDF]

Acta Amazonica, 2018
The State of Acre, in the southwestern Brazilian Amazon, harbors high biodiversity and a high degree of endemisms. Nevertheless, there are few studies on the diversity of social wasps occurring in this region.

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

Oikos, EarlyView.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

Oikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Predation of Chlorostilbon lucidus (Shaw, 1812) (Apodiformes: Trochilidae) hummingbird chicks by Polistes canadensis (Linnaeus, 1758) (Polistinae: Polistini): A new predatory interaction documented in the Brazilian Caatinga

Entomological Communications
Non-aggressive interactions between Neotropical social wasps (Vespidae) and birds frequently occur but remain poorly understood. Typically categorized as commensalism, where birds benefit while no advantages for the wasps have been documented, the ...

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Yellow does not improve the efficiency of traps for capturing wasps of the genera Vespula and Dolichovespula (Hymenoptera: Vespidae)

European Journal of Entomology, 2019
Social wasps are often considered as nuisance pests in urban environments and are often controlled by using traps. The majority of commercially produced traps for catching wasps have yellow as the dominant colour around the trap entrance.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.

Flower-Visiting Social Wasps and Plants Interaction: Network Pattern and Environmental Complexity

Psyche: A Journal of Entomology, 2012
Network analysis as a tool for ecological interactions studies has been widely used since last decade. However, there are few studies on the factors that shape network patterns in communities.

Nesting Ecology of Polistes Species (hymenoptera, Vespidae) in Urban Areas of South-western Iberian Peninsula

Sociobiology, 2020
Urbanization is increasing across the globe and it is recognized as a major factor affectingspecies, populations and assemblages. Although urbanization is recognized as a major threat to biodiversity, there is increasing evidence that urban habitats may ...
