Accuracy of occurrence and abundance estimates from insect metabarcoding

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2343-2363, August 2026.
Abstract DNA metabarcoding—high‐throughput sequencing of barcode regions from bulk samples—has become a key tool for insect biodiversity assessment. Yet, how methodological choices affect the accuracy of metabarcoding data remains insufficiently explored. In this paper, we ask: (1) How does the lysis method (non‐destructive lysis vs.

Annual flower strips under the ‘Sweden Blossom’ initiative – how do they perform for pollinators, natural enemies and herbivores?

Agricultural and Forest Entomology, Volume 28, Issue 3, Page 458-470, August 2026.
Pollinator‐targeted annual flower strips increase abundances of pollinators but also natural enemies and herbivores. Natural enemies and herbivores disperse in a taxon‐specific manner into nearby crops. Pest control by ground‐dwellers slightly increases in crop areas near the flower strips.

The wild honeybee population of Europe is in decline: Evidence from monitoring studies

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Studying the population trends of wild honeybees is possible when considering that managed and wild colonies form different subpopulations within regional honeybee metapopualtions. Abstract Populations of wild western honeybees (Apis mellifera) have been neglected because the species has been considered to consist of managed colonies only.

Plant Traits and Reproduction in a Multitrophic System: The Role of Aphids, Parasitoids and Hyperparasitoids

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 822-830, August 2026.
This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...

Bumblebees mediate landscape effects on a forest herb's population genetic structure in European agricultural landscapes

Ecology and Evolution
Spatially isolated plant populations in agricultural landscapes exhibit genetic responses not only to habitat fragmentation per se but also to the composition of the landscape matrix between habitat patches.

Impacts of a Sweet Orange Essential Oil–Based Biopesticide on Exorista larvarum, a Parasitoid Tachinid Fly With a Dual Role

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 933-941, August 2026.
Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.

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

Ecological Entomology, Volume 51, Issue 4, Page 799-809, August 2026.
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

Pollination Under Pressure: Grazing and Nutrient Enrichment Reshape Arctic Pollinator Communities and Interaction Networks

Global Change Biology, Volume 32, Issue 8, August 2026.
Grazing exclusion reshaped Arctic flower‐visitor communities, increased plant‐pollinator interactions, and altered interaction networks, while nutrient enrichment had weaker, context‐dependent effects. Together the two drivers produced both independent and interactive effects, with tundra grasslands showing the greatest sensitivity to environmental ...
