2023 journal article

Differential bumble bee gene expression associated with pathogen infection and pollen diet

BMC Genomics, 24(1).

By: J. Giacomini n, L. Adler *, B. Reading n  & R. Irwin n

author keywords: Sunflower pollen; Bumble bee; Parasitism; Immune transcripts; Gut epithelial cells; Detoxification
MeSH headings : Bees / genetics; Animals; Pollen / genetics; Helianthus / genetics; Crithidia / genetics; Diet; Gene Expression
TL;DR: D dissimilar immune responses between sunflower- and wildflower-fed bumble bees infected with C. bombi indicate a response to physical damage to gut epithelial cells caused by sunflower pollen, and a strong detoxification response toSunflower pollen consumption. (via Semantic Scholar)

2022 journal article

Sunflower pollen induces rapid excretion in bumble bees: Implications for host-pathogen interactions

Journal of Insect Physiology, 137, 104356.

By: J. Giacomini n, N. Moore  n, L. Adler * & R. Irwin n

author keywords: Host physiology; Host-pathogen interactions; Insect excretory system; Protozoan pathogens; Rapid excretion
MeSH headings : Animals; Bees; Crithidia / physiology; Diet; Helianthus; Host-Pathogen Interactions; Pollen
TL;DR: It is shown that a sunflower pollen diet can affect host physiology gut function, causing more rapid and greater excretion, which provides important insight into a mechanism that could underlie the medicinal effect ofSunflower pollen for bumble bees. (via Semantic Scholar)

2022 journal article

Sunflower pollen reduces a gut pathogen in the model bee species, <i>Bombus impatiens , but has weaker effects in three wild congeners

By: A. Fowler *, J. Giacomini n, S. Connon  n, R. Irwin n & L. Adler *

author keywords: bee pathogen; pollinator; pollen; Bombus; sunflower; Crithidia
MeSH headings : Animals; Bees; Crithidia / physiology; Diet; Helianthus; Parasites; Pollen
TL;DR: Sunflower pollen could control Crithidia infections in B. impatiens and potentially close relatives, but may hinder reproduction if other resources are scarce, and be interpreted carefully as findings may not relate to all bee species. (via Semantic Scholar)

2021 journal article

The costs and benefits of sunflower pollen diet on bumble bee colony disease and health

Ecosphere, 12(7).

By: J. Giacomini n, S. Connon  n, D. Marulanda n, L. Adler * & R. Irwin n

author keywords: bee health; conservation; disease ecology; parasitology; pollination biology; pollination services; tri-trophic interactions
TL;DR: Evidence is provided that sunflower pollen as part of a mixed pollen diet can reduce infection in individual bees and whole colonies with no significant nutritional trade-offs for colony worker production and most aspects of colony reproduction. (via Semantic Scholar)

2018 journal article

Medicinal value of sunflower pollen against bee pathogens

Scientific Reports, 8(1).

By: J. Giacomini n, J. Leslie *, D. Tarpy n , E. Palmer-Young *, R. Irwin n & L. Adler *

MeSH headings : Animals; Bees / parasitology; Crithidia / growth & development; Helianthus; Nosema / growth & development; Pollen
TL;DR: It is discovered that sunflower pollen dramatically and consistently reduced a protozoan pathogen infection in bumble bees and also reduced a microsporidian pathogen of the European honey bee, indicating the potential for broad anti-parasitic effects. (via Semantic Scholar)
