Castes and Polymorphisms in Neotropical Social Wasps

, 2020
Neotropical social wasps have a set of chimeric characteristics that make them unique and difficult to fit into current theories on the evolution of social behavior (Noll and Wenzel, Biol J Linn Soc 93: 509–22, 2008). Among them, the presence of more than one functional queen (polygyny), absence of strong morphological differentiation, and flexibility ...

Social wasps as models to study the major evolutionary transition to superorganismality.

Current Opinion in Insect Science, 2018
The major evolutionary transition to superorganismality has taken place several times in the insects. Although there has been much consideration of the ultimate evolutionary explanations for superorganismality, we know relatively little about what ...

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Comparative nesting success of the keyhole mud-dauber (Hymenoptera, Crabronidae, Trypoxylon nitidum) in different substrates

Journal of Hymenoptera Research, 2016
The solitary wasp Trypoxylon nitidum F. Smith nests in a variety of existing cavities. Nesting success – the fraction of completed, provisioned cells that produced adult offspring – can be estimated by examination of old cells.

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

Nordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

Examining the multi‐disciplinary origins of biophobia towards threatening and non‐threatening wildlife in a highly urbanised city in China

People and Nature, EarlyView.
Abstract Urbanisation is reshaping how people experience wildlife, reducing our shared spaces with local biodiversity. Fewer opportunities for human–wildlife interactions weaken our emotional attachments to nature and precipitate a loss of species knowledge and familiarity.

Foraging of Protopolybia exigua (Saussure, 1854) (Vespidae: Polistinae) on Salvinia auriculata Aubl. (Salviniaceae) in an urban environment in Southeast Brazil

Heringeriana
There is limited information regarding the plant species from which social wasps extract fibers as raw material for nest construction, as well as their foraging behavior for such materials.

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.

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.

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.
