Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

Entomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, Volume 82, Issue 9, Page 8132-8151, September 2026.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Habitat-specific variation in gut microbial communities and pathogen prevalence in bumblebee queens (Bombus terrestris). [PDF]

PLoS ONE, 2018
Gut microbial communities are critical for the health of many insect species. However, little is known about how gut microbial communities respond to anthropogenic changes and how such changes affect host-pathogen interactions.

Temperature Alters Specificity in a Host–Parasite Interaction

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The Red Queen Hypothesis predicts that host–parasite coevolution maintains genetic variation through strong genetic specificity, but this specificity may be sensitive to environmental conditions. Using Meloidogyne arenaria and its parasite Pasteuria penetrans, we tested host–parasite interactions across three temperatures and found specificity at two ...

Integrating the Microbiome Into Infection Ecology and Evolution in Wild Animals

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Parasites are a ubiquitous force in nature threatening wildlife populations and ecosystems. Interactions between hosts and their parasites are impacted by host‐associated microbiomes, which are essential for host development, physiology and immunity.

Pollen as Bee Medicine: Is Prevention Better than Cure?

Biology, 2023
To face environmental stressors such as infection, animals may display behavioural plasticity to improve their physiological status through ingestion of specific food.

Multiple Key Hosts and Network Structure Shape Viral Prevalence Across Multispecies Communities of Bees

Ecology Letters, Volume 29, Issue 2, February 2026.
This study develops a quantitative framework that integrates field data, epidemiological models, simulations, and Bayesian inference to identify key viral hosts in multispecies bee communities. By estimating species‐specific R0 values from flower‐visitor networks and viral screening, we show that honeybees, as well as other wild bees, can drive the ...

Long-term prevalence of the protists Crithidia bombi and Apicystis bombi and detection of the microsporidium Nosema bombi in invasive bumble bees [PDF]

, 2020
An initial survey in 2009 carried out at a site in northwestern Patagonia region, Argentina, revealed for the first time in South America the presence of the flagellate Crithidia bombi and the neogregarine Apicystis bombi, two pathogens associated with ...
