Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee

Stunning Intricacies of RNA Editing Complexes RECC, RESC, and REH2C: Functional Organization, Developmental Regulation, and Evolutionary History in Kinetoplastid Protists

open access: yesWIREs RNA, Volume 17, Issue 2, March/April 2026.
U‐indel RNA editing targets mRNA:gRNA duplexes through three key complexes that collectively govern assembly, specificity, catalysis, and developmental regulation. Modern tools, including artificial intelligence, analyze the organization, dynamics, and evolution of the remarkable holo‐editosome, opening new avenues in RNA biology and therapy.

Diversity of phlebotomine sand flies and molecular detection of trypanosomatids in Brumadinho, Minas Gerais, Brazil.

open access: yesPLoS ONE, 2020
This study aimed to describe the sand fly fauna and detect trypanosomatids in these insects from Casa Branca, state of Minas Gerais, Brazil, an endemic area of both visceral (VL) and tegumentary leishmaniasis (TL).

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

open access: yesEcology 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 ...

Testing Dose-Dependent Effects of the Nectar Alkaloid Anabasine on Trypanosome Parasite Loads in Adult Bumble Bees.

open access: yesPLoS ONE, 2015
The impact of consuming biologically active compounds is often dose-dependent, where small quantities can be medicinal while larger doses are toxic. The consumption of plant secondary compounds can be toxic to herbivores in large doses, but can also ...

Resource supplementation later in the colony cycle improves real‐world bumblebee colony survival

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our findings suggest that B. terrestris colonies became food‐limited towards the end of their colony cycle in early summer. We suggest ecological intensification through planting native wildflower species may be more effective if it targets this flowering period, particularly within heavily arable areas, and that a staggered patchwork of mowing or ...

Leishmania RNA Virus and Its Impact on Drug Response and Clinical Outcomes in Leishmaniasis: A Comprehensive Review

open access: yesJournal of Parasitology Research, Volume 2026, Issue 1, 2026.
Leishmania RNA viruses (LRVs) have emerged as significant modulators of disease severity, therapeutic response, and clinical outcomes in various forms of leishmaniasis. This review provides a comprehensive overview of the current knowledge surrounding LRV1 and LRV2, focusing on their taxonomy, molecular biology, epidemiological patterns, and pathogenic

The role of gallery forests in maintaining Phlebotominae populations: potential Leishmania spp. vectors in the Brazilian savanna

open access: yesMemorias do Instituto Oswaldo Cruz
BACKGROUND Knowledge on synanthropic phlebotomines and their natural infection by Leishmania is necessary for the identification of potential areas for leishmaniasis occurrence.

Does pathogen spillover from commercially reared bumble bees threaten wild pollinators? [PDF]

open access: yesPLoS ONE, 2008
The conservation of insect pollinators is drawing attention because of reported declines in bee species and the 'ecosystem services' they provide. This issue has been brought to a head by recent devastating losses of honey bees throughout North America ...

Animal medical systems from Apis to apes: history, recent advances and future perspectives

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2608-2624, December 2025.
ABSTRACTAnimal medical systems encompass a wide range of behaviours aimed at maintaining or improving health. It has become clear that these behaviours are not limited to animals treating themselves (self‐medication) but also include the treatment of group members, resulting in the adoption of the more inclusive term “animal medication”. Behaviour with
