Investigating trade-offs between ovary activation and immune protein expression in bumble bee (<i>Bombus impatiens</i>) workers and queens

By: A. Mcafee n, A. Chapman*, G. Bao*, D. Tarpy n & L. Foster*

author keywords: resource allocation; trade-off; immunity; reproduction; bumble bees; proteomics
TL;DR: Proteomics is used to interrogate the patterns of immune protein expression of female bumble bees by sampling queens at different stages of their life cycle, then by sampling workers with different degrees of ovary activation to investigate patterns of immune protein expression associated with ovary activation.

Drone honey bees are disproportionately sensitive to abiotic stressors despite expressing high levels of stress response proteins

COMMUNICATIONS BIOLOGY, 5(1).

By: A. McAfee n, B. Metz n, J. Milone n, L. Foster* & D. Tarpy n

MeSH headings : Animals; Bees / drug effects; Bees / physiology; Cold Temperature; Female; Gene Expression Regulation / drug effects; Male; Neonicotinoids / toxicity; Nitro Compounds / toxicity; Pesticides / toxicity; Sex Factors; Stress, Physiological
TL;DR: Surprisingly, although drones are more likely to die from some stressors than workers, they exhibit higher baseline stress response proteins, suggesting that drones’ stress tolerance systems are fundamentally rewired relative to workers, and susceptibility to stress depends on more than simply gene dose or allelic diversity.

Honey bee queen health is unaffected by contact exposure to pesticides commonly found in beeswax

SCIENTIFIC REPORTS, 11(1).

By: A. McAfee n, J. Milone n, B. Metz n, E. McDermott n, L. Foster* & D. Tarpy n

MeSH headings : Animals; Beekeeping; Bees / drug effects; Bees / physiology; Dose-Response Relationship, Drug; Environmental Exposure / adverse effects; Environmental Exposure / analysis; Fat Body / drug effects; Fat Body / metabolism; Female; Insect Proteins / drug effects; Insect Proteins / metabolism; Male; Oviposition / drug effects; Pesticide Residues / analysis; Pesticide Residues / toxicity; Pesticides / analysis; Pesticides / toxicity; Proteomics; Reproduction / drug effects; Sperm Count; Waxes / chemistry; Waxes / toxicity
TL;DR: It is suggested that previously reported associations between high levels of pesticide residues in wax and queen failure are most likely driven by indirect effects of worker exposure (either through wax or other hive products) on queen care or queen perception. (via Semantic Scholar)

Queen honey bees exhibit variable resilience to temperature stress

PLOS ONE, 16(8).

By: A. McAfee n, D. Tarpy n & L. Foster*

MeSH headings : Acclimatization / physiology; Animals; Bees / physiology; Biomarkers / metabolism; Cell Survival; Female; Gene Expression Regulation; Hot Temperature; Insect Proteins / metabolism; Male; Mass Spectrometry; Ovum / metabolism; Proteomics / methods; Spermatozoa / metabolism; Spermatozoa / physiology
TL;DR: It is found that cold stress, but not heat stress, reduced stored sperm viability; however, there was no significant effect of temperature stress on any other recorded metrics (queen mass, average callow worker mass, laying patterns, the egg proteome, and queen spermathecal fluid proteome).

Trade-offs between sperm viability and immune protein expression in honey bee queens (Apis mellifera)

COMMUNICATIONS BIOLOGY, 4(1).

MeSH headings : Animals; Bees / immunology; Bees / metabolism; Bees / virology; Cell Survival; Female; Insect Proteins / metabolism; Male; Proteome; Reproduction; Serpins / metabolism; Spermatozoa
TL;DR: Quality metrics and viral loads of honey bee queens from nine genetic sources are surveyed and it is found that lower measures of fertility correlated with high levels of the immune effector lysozyme, consistent with a trade-off between immunity and fertility. (via Semantic Scholar)

Candidate stress biomarkers for queen failure diagnostics

BMC GENOMICS, 21(1).

author keywords: Honey bees; Queens; Sperm viability; Biomarkers; Proteomics; Stressors; Spermatheca
MeSH headings : Bees; Biomarkers; Pesticides
TL;DR: It was found that heat-shocking queens for upwards of 1 h at 40 °C was necessary to induce significant changes in the two strongest candidate heat-shock markers, and that relative humidity significantly influenced the degree of activation. (via Semantic Scholar)

MeSH headings : Adaptation, Physiological / drug effects; Animals; Bees / drug effects; Bees / enzymology; Environmental Monitoring / methods; Esterases / metabolism; Larva / drug effects; Larva / enzymology; North America; Pesticides / toxicity; Pollination
TL;DR: It is suggested that selective breeding may inadvertently increase honey bees' sensitivity to pesticides, whereas unselected, putatively feral and Old World stocks have larvae that are more tolerant. (via Semantic Scholar)

Vulnerability of honey bee queens to heat-induced loss of fertility

NATURE SUSTAINABILITY, 3(5), 367–376.

By: A. McAfee n, A. Chapman*, H. Higo*, R. Underwood*, J. Milone n, L. Foster*, M. Guarna*, D. Tarpy n, J. Pettis*

TL;DR: It is found that queens have two potential routes of temperature-stress exposure: within colonies and during routine shipping, and data suggest that temperatures of 15–38 °C are safe for queens at a tolerance threshold of 11.5%, which is the viability difference associated with queen failure in the field.

Feminizer and doublesex knock-outs cause honey bees to switch sexes

PLOS BIOLOGY, 17(5).

By: A. McAfee n, J. Pettis*, D. Tarpy n & L. Foster*

TL;DR: Using clustered regularly interspaced short palindromic repeats (CRISPR) to knock out two key genes (feminizer and doublesex) that guide sexual development yielded remarkably low rates of genetic mosaicism and offers a promising tool for engineering and phenotyping bees for diverse applications.
