A toxicogenomics approach reveals characteristics supporting the honey bee (Apis mellifera L.) safety profile of the butenolide insecticide flupyradifurone [PDF]

, 2021
Flupyradifurone, a novel butenolide insecticide, selectively targets insect nicotinic acetylcholine receptors(nAChRs), comparable to structurally different insecticidal chemotypes such as neonicotinoids and sulfoximines.

Deep Learning Approaches for Image-Based Classification of Honey Bee (Apis mellifera) Lineages

Türkiye Tarımsal Araştırmalar Dergisi
Honey bees (Apis mellifera) play a vital role in maintaining ecosystem balance and supporting the sustainability of agricultural production. Accurate classification of these insects at the species and subspecies levels is essential for biodiversity monitoring, understanding local adaptation, and developing effective conservation strategies.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Diversity of the Microbiomes in the Larval and Adult Stages of the European Cherry Fruit Fly (Rhagoletis cerasi) and Identification of Potential Biocontrol Candidate Taxa

Entomologia Experimentalis et Applicata, EarlyView.
First comprehensive characterization of the R. cerasi microbiome is reported. Stage‐specific variations in microbial composition are documented. Multiple bacterial entomopathogen taxa are identified as potential biocontrol candidates for R. cerasi.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Evaluating cape honey bee sperm quality and the in vitro effect of miticides on sperm functionality and structure [PDF]

, 2021
Magister Scientiae (Medical Bioscience) - MSc(MBS)Apis mellifera (honey bees) are essential pollinators and thus considered a keystone species. Reproductive success is therefore important to the survival of the species, with drone sperm quality playing a

MtDNA Analysis Indicates Human-Induced Temporal Changes of Serbian Honey Bees Diversity

Insects, 2021
Local populations of Apis mellifera are rapidly changing by modern beekeeping through the introduction of nonnative queens, selection and migratory beekeeping.

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

Plant Biology, EarlyView.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...

Using the Software DeepWings© to Classify Honey Bees across Europe through Wing Geometric Morphometrics

Insects, 2022
DeepWings© is a software that uses machine learning to automatically classify honey bee subspecies by wing geometric morphometrics. Here, we tested the five subspecies classifier (A. m. carnica, Apis mellifera caucasia, A. m.
