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

open access: yesEcological 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

Computer Vision for Monitoring Wild Bees and Wasps: A Structured Literature Review

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This review surveys recent (2020–2026) computer vision research on automated monitoring of wild bees and wasps, covering tasks such as species detection, habitat observation, and behavior analysis. It analyzes datasets, public resources, hardware, and software development.

A larval hunger signal in the bumblebee Bombus terrestris

open access: yesInsectes Sociaux, 2006
Larvae of Bombus terrestris, a pollen-storing bumblebee, are dependent on progressive provisioning by workers. We test the hypothesis that larval cuticular chemicals can act as a hunger signal. We first show with a new classical conditioning experiment, using a Y-shaped tube, that workers can be trained to prefer the extracts of normally fed larvae ...

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

A core linkage map of the bumblebeeBombus terrestris

open access: yesGenome, 2006
The bumblebee Bombus terrestris is an economically important pollinator and an emerging model species in quantitative and population genetics. We generated genetic linkage maps for 3 independent mapping populations of B. terrestris. The linkage map with the highest resolution had 21 linkage groups, which adequately represents the haploid chromosome ...

How landscape, pollen intake and pollen quality affect colony growth in Bombus terrestris

open access: yes, 2016
Context: Abundance and diversity of bumblebees have been declining over the past decades. To successfully conserve bumblebee populations, we need to understand how landscape characteristics affect the quantity and quality of floral resources collected by

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Multi‐Omics Analyses Elucidate the Venom Components of the Wasp Vespa mandarinia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
The wasp Vespa mandarinia was widely reared in Yunnan province. The venom was responsible for their aggressive behavior. Tweety proteases, hyaluronidase, venom dipeptidyl peptidase 4, and phospholipase A1 and A2 isozyme were identified. In addition, organic heterocyclic compounds, organic acids, and derivatives were found.
