Managed honeybees aggressively displace wild pollinators from crucial food sources, according to a recent study published on September 12, 2026, which recorded 300 competitive interactions between insect species [3][4][5][6][7][8][10]. Researchers observed that honeybees frequently won foraging contests, often by chasing away other insects [3][4][5][6][8].

This finding raises significant concerns for the health of wild pollinator populations, which are vital for ecosystem function across the United Kingdom and beyond [5][7][9]. The study suggests that an increasing number of managed honeybee colonies may intensify competitive pressures on vulnerable native insect species, impacting biodiversity and ecological stability [5][7].

## What the records show

The study, led by PhD student Victoria A. Buckle and senior author Dr. Tom Ings at Anglia Ruskin University (ARU), appeared in the journal *Ecological Entomology* [3][6][9]. Conducted over two years, from 2023 to 2024, observations took place at five sites in and around Cambridge, UK [2][3][4][5][6][10]. All study locations were within 300 meters of known honeybee colonies [2][4][5][6][10]. Researchers focused on pollinators foraging on bramble (*Rubus fruticosus*) and ivy (*Hedera helix*), plants that provide important nectar and pollen and attract many visitors when in bloom [2][3][4][5][6][7][8][10].

The research team observed 300 pairs of interactions during 93 hours of fieldwork, categorizing flower visitors into honeybees, bumblebees, solitary bees, hoverflies, and an "other" group including butterflies, beetles, and wasps [2][3][4][5][6][7]. Outcomes were recorded as a "win" if one pollinator gained access to a flower, a "loss" if prevented, or a "share" if both accessed without conflict [2][3][4][5][6][7].

Higher densities of honeybees correlated with both fewer wild pollinators and more frequent competitive interactions [2][4][5][6]. Honeybees secured a higher proportion of "wins" in these encounters [2][3][4][5][6]. Specifically, a doubling of honeybee density on bramble was linked to a 14% reduction in bumblebee abundance [2][4][5][6]. An increase in honeybees on ivy corresponded with fewer solitary bees and hoverflies [4][5][6]. Honeybees often instigated these competitive interactions, winning resources by chasing away other insects [4][5][6]. Other pollinators actively avoided honeybees in 28% of interactions on bramble and 36% on ivy [3][5][8]. Honeybees physically displaced or chased rival pollinators in at least one in five winning outcomes on both plant species [3][5][8]. An exception to this pattern was the ivy bee, a non-native solitary bee, which successfully defended its food source by displacing honeybees [5][8]. The study's findings "add new depth to existing literature about behavioural interactions among honeybees and non-Apis pollinators," evidencing interference competition [3].

## The timeline

The study was conducted over a two-year period, from 2023 to 2024, in Cambridgeshire, UK [3][10]. The findings were published in the journal *Ecological Entomology* on September 12, 2026 [3].

## What changed and for whom

The context for this study includes a significant increase in registered beekeepers in the UK. The number of registered beekeepers more than doubled, rising from 19,000 in 2010 to 47,000 by 2025 [7]. This surge has led to more managed honeybee hives [7]. Researchers also observed that competitive interactions became more frequent with rising temperatures, suggesting climate change could intensify competition [5][8].

## What the subject has said publicly

Lead author Victoria Buckle, a PhD student at Anglia Ruskin University, stated the study's aim is "not to discourage beekeeping, but to better understand how competition happens between wild and managed pollinator species with the aim of helping to conserve our wild pollinators, which play such an important ecological role" [9].

## What we could not confirm

We could not confirm specific policy actions or conservation strategies that are being considered by UK authorities in response to these findings. We also could not confirm the global applicability of these specific competitive behaviors or detailed long-term population trends for individual wild pollinator species mentioned.
