Eye can see clearly now: Identifying the locus associated with a white‐eye mutation in honey bees (Apis mellifera)

Insect Molecular Biology, EarlyView.
We performed a community science investigation with the beekeepers nationwide to find phenotypic mutants. Alongside a beekeeper in Kentucky, we performed a GWAS to identify a region associated with a white‐eye phenotype. We identified an eight bp region in a non‐coding RNA strongly associated with white eyes.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Balarılarında ( Apis mellifera L. ) hormonlar ve feromanlar

, 1993
SUMMARY Hormones and Pheromones take very important place with their effect on the growth, metamorphism, development, reproduction, heredity, action, digestion, nerval activities and endocrin activity in insects world. In this study hormones were discussed generally but juvenile hormone was taken as a first important are with it's important effect

Genome‐wide and gene‐specific DNA methylation across developmental stages in Pogonomyrmex californicus: A socially polymorphic ant

Insect Molecular Biology, EarlyView.
Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

Is Nocturnal Pollination Important for Crop Production? Experimental Evidence From Small Fruit Crops

Journal of Applied Entomology, EarlyView.
ABSTRACT Insect‐mediated pollination is essential for crop production but is mainly studied considering diurnal pollinators only. Here, we use pollinator exclusion techniques to prevent either diurnal or nocturnal insect visits in small fruit crops: raspberry (Rubus idaeus), over 1 year, and red currant (Ribes rubrum) and black currant (Ribes nigrum ...

Determining Terminal Velocities of Selected Insects and Substitute Materials to Develop Future Test Procedures for Insect‐Friendly Mowing Technology

Journal of Applied Entomology, EarlyView.
ABSTRACT Agricultural grasslands are vital habitats for insects that provide key ecosystem services. However, conventional rotary mowers are proposed to cause significant insect mortality due to the high rotational speed of their blades and the resulting airflow.
