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.

Floral reward traits change between sexual phases in two Helleborus species

Scientific Reports
Nectar and pollen attractants as well as visitors in Helleborus viridis ssp. viridis and H. purpurascens (Ranunculaceae), i.e. European species, were studied during two flowering seasons.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

From moths to microbes: investigating reproductive biology, pollination and nectar in Platanthera Transversa (Suskd.) R.M. Bateman (Orchidaceae)

Journal of Plant Interactions
Platanthera transversa is a common orchid in western North America yet it is poorly studied. This makes it difficult to understand the breadth of pollinators and floral attractant mechanisms present, both of which are vital to understanding the dynamics ...

No evidence of a decoy effect in bees: Rewardless flowers do not increase bumblebees' preference for neighbouring flowers

Ecological Entomology, EarlyView.
Many plants retain nectarless flowers; we tested whether these act as “decoys” for bees by making neighbouring rewarding flowers seem more valuable—a cognitive bias known as the decoy effect. The presence of decoy flowers did not shift bumblebee preferences between two equally rewarding inflorescences, and bees quickly learned to avoid these nectarless

Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

Ibis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

Assessment of Floral Nectar and Amino Acid Yield in Eight Landscape Trees for Enhanced Pollinator Food Resources in Urban Forests

Plants
Urban environments pose challenges for pollinators due to habitat loss and limited floral resources. However, green infrastructure, particularly street and ornamental trees, can play a critical role in supporting urban pollinator communities.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Sheep and cattle grazing regimes differentially affect ground beetle and ant communities in Mediterranean cork oak woodlands

Insect Conservation and Diversity, EarlyView.
Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

Journal of Applied Entomology, EarlyView.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...
