Most terrestrial invertebrates are in considerable decline, and the range expansion of invasive hornet, Vespa velutina nigrithorax, poses an additional threat. Although now found much western Europe, full extent hornet's predatory activity remains unexplored. While impacts on honey bees well-documented, evidence a wider dietary spectrum is emerging, indicating potentially broad ecological ramifications. Here, we conduct first large-scale study diet V. velutina, utilising deep sequencing to characterise larval gut contents over 1500 samples from Jersey, France, Spain, UK. Our results indicate that highly flexible predator, enabling its continued capacity. Analyses detected 1449 taxa, with greater prey richness southern latitudes, spatiotemporal variation composition. Hymenoptera, Diptera, Hemiptera, Coleoptera, Lepidoptera, Araneae were most frequently occurring orders predated, each characterised by high taxonomic diversity. The bee Apis mellifera was abundant species, being all sampled nests showing relative read numbers increasing apiary density proximity, supporting concerns for impact apiculture. Notably, 43 50 commonly predated also flower visitors, including 4 common bumblebee substantial risks wild pollinators. These data provide wide support risk evaluation this species potential environmental as it spreads across Europe.

New problems for old vineyards: Mitigating the impacts of yellow-legged hornets (Vespa velutina) in a historical wine-producing area

Traditional small-sized vineyards are especially sensitive to different impacts, including the arrival of new pests. The adults yellow-legged hornet (Vespa velutina), an invasive alien species present in Iberian Peninsula since 2010, feed on sugary foods, causing crop losses vineyards. However, management techniques for control V. velutina limited, and they do not provide effective agricultural settings. This work aims evaluate use exclusion system a traditional non-mechanized vineyard highly invaded area by NW Spain (Protected Geographical Indication Betanzos, Galicia) as method mitigate damage caused hornets. Anti-hail nets were used factorial design experiment with groups netted unnetted vines two white wine cultivars order address production loss. In particular, we aim 1) asses effectiveness anti-hail netting preventing grape yield loss, 2) assess impact ripening incidence bunch fungal infection, 3) study potential relationship between diseases. Results show that tested increases yield, it prevents effectively both hornets birds. No significant correlation diseases was found either cultivar. increased slightly final sugar content one cultivars, well damage. We discuss implications this within framework land abandonment loss landscapes.

Comparative morphological analysis of mature larvae of eight Vespa Linnaeus, 1758 species (Hymenoptera, Vespidae) in South Korea

Journal of Hymenoptera Research, Год журнала: 2025, Номер 98, С. 435 - 465

Опубликована: Апрель 8, 2025

The social wasp genus Vespa , encompassing insects commonly referred to as hornets, consists of 22 species that are predominantly distributed across the Palearctic and Indomalayan regions. These harmful pests, often spread through trade, pose risks public health. Hornet larvae undergo development within protected environment nests. Hence, they may exhibit more conserved characteristics than adults, which face direct selection pressure. To date, larval morphology has been studied in only approximately half known hornet species, in-depth comparative research on is scarce. In South Korea, comprehensive descriptions identification keys for eight reported two subspecies lacking. address this gap, study aimed provide morphological mature from Korea. Between 2021 2024, were collected nests observed under scanning electron microscopy, optical stereo microscopy evaluate various characteristics. Results indicated distinguishing morphologically other taxonomic groups challenging. Specifically, no significant differences noted between V. velutina nigrithorax simillima . lack distinctive features complicates identification, making it challenging compared adult specimens.

Honey bees are vital to human well-being and under multiple stresses. We need be able assess the viability productivity of honey bee colonies in different landscapes management climate change scenarios. have developed a prototype digital twin, HONEYBEE-pDT, based on BEEHAVE model, which simulates foraging, population dynamics Varroa mite infestation single colony. The main input data land cover maps daily weather data. Users can run pDT for specific site or larger areas, up whole Germany. Hive weight from hundreds hives will used calibration validation.

Using the Beehave Honey Bee Model Across Climates: Emerging Instead of Imposed Queen Egg-Laying Rate and the Influence of Weather Conditions, Pollen Storage and Brood Size

Опубликована: Янв. 1, 2024

Multiple stressors threaten honey bees and increase the risk of colony mortality. Empirical studies to determine relative importance critical stress levels are not feasible because most characteristics cannot be controlled. Modelling bee colonies can help fill this gap. The BEEHAVE model is well acknowledged analysis impacts local land use, including pesticide weather, mite infestation beekeeping practices on However, it based an imposed egg-laying rate which only representative average central European conditions at same time main driving factor for dynamics. We developed a modified version, BEEHAVE-PPE (Pollen Pheromone Egg laying), where maximum depends pollen storage intake. assumed that daily foraging, thus uptake, but also brood size, pheromones, temperature. was successfully calibrated using demographic weather data from monitoring area in France. While our yet unverified assumptions concerning pheromone production dynamics therefore needs further empirical confirmation, results indicate possible let emerge climate feedbacks brood.

Density of predating Asian hornets at hives disturbs the 3D flight performance of honey bees and decreases predation success

Abstract Automated 3D image‐based tracking systems are new and promising devices to investigate the foraging behavior of flying animals with great accuracy precision. analyses can provide accurate assessments flight performance in regard speed, curvature, hovering. However, there have been few applications this technology ecology, particularly for insects. We used analyze behavioral interactions between Western honey bee Apis mellifera its invasive predator Asian hornet, Vespa velutina nigrithorax . investigated whether predation success could be affected by hovering hornet bees front one beehive. recorded a total 603,259 trajectories 5175 predator–prey leading 126 successful events, representing 2.4% success. Flight speeds hornets hive entrances were much lower than that their prey; contrast capacity, while curvature range overlapped two species. There large differences exit entrance flights bees. Interestingly, we found density both hornets. Higher led decrease speed leaving hive, an increase entering together more curved trajectories. These effects suggest some avoidance resulted Results showed when number increased up 8 individuals, above which decreased, likely due competition among predators. Although based on single colony, study reveals interesting outcomes derived from use automated derive measures individual
