Cage Types, Nutrition, and Care
In the fascinating world of honey bees, the queen is more than just a monarch—she is the very heart of the colony, responsible for its growth, genetic diversity, and ultimate survival. Beekeepers and researchers often face the challenge of keeping virgin queens alive outside their colonies for short periods, whether for breeding programs, research purposes, or commercial distribution.
The temporary storage of these precious queens is a delicate art that requires precise conditions to ensure their survival and future acceptance back into colonies. Recent scientific investigations have revealed that the type of cage used, the food provided, and the presence of attendant workers can dramatically affect a queen's chances of survival during this critical period.

Beekeepers and researchers temporarily cage honey bee queens for several important reasons. Commercial queen rearing often involves transporting mated queens from specialized breeders to beekeepers who need to replace failing queens or establish new colonies 1 .
Virgin queens may also be held outside the colony as part of selective breeding programs, allowing time for genetic testing or evaluation of physical characteristics before introduction to a mating nucleus hive. This practice is particularly valuable when beekeepers want to screen many queens for specific traits, as only a small percentage may meet the desired criteria.
Virgin honey bee queens face specific physiological challenges during temporary storage. Unlike workers, queens have not evolved to perform foraging activities or feed themselves independently. They rely on worker bees for nourishment and care, which makes them particularly vulnerable when isolated without attendants 1 .
Additionally, queens destined for mating have a limited biological window for successful mating and introduction to colonies—typically around one week of age—which corresponds to their natural mating schedule.
Researchers designed a comprehensive experiment to test three key factors that might influence virgin queen survival during temporary storage: cage type (wooden versus plastic), food type (sugar candy, honey, or both), and the presence or absence of attendant worker bees. The experiment employed a complete three-way factorial design, resulting in 12 unique combinations of these factors 1 .

The experiment yielded fascinating insights into how different factors affect virgin queen survival during temporary storage. While all 12 combinations showed high survival rates (90-100%) during the first three days, significant differences emerged by day seven, with survival rates ranging from 0% to 100% across the different combinations 1 .
| Cage Type | Food Type | Attendant Workers | Survival Rate at Day 7 |
|---|---|---|---|
| Wooden | Honey | Present | 100% |
| Wooden | Candy | Present | 70% |
| Wooden | Candy + Honey | Present | 60% |
| Plastic | Honey | Present | 10% |
| Wooden | Honey | Absent | 40% |
| Plastic | Honey | Absent | 0% |
The dramatic differences in survival rates across the experimental combinations reveal important insights into honey bee biology and the specific needs of virgin queens. The superior performance of wooden cages with honey and attendants suggests that queens benefit from the absorbent properties of wood, which likely helps maintain optimal humidity levels and prevents food spoilage 1 .
Across all combinations, queens with attendants showed significantly higher survival rates (53%) compared to those without attendants (18%) 1 .
Plastic cages with honey resulted in particularly poor survival rates, suggesting negative interactions between materials and food types.
Based on these findings, beekeepers who need to store virgin queens for up to one week should:
Essential materials and equipment for conducting queen cage research, based on the methodologies used in this study.
Function: Provide housing with absorbent properties that maintain optimal humidity levels and prevent food spoilage.
Example: "Three-hole" wooden cages with metal mesh tops were used in the study.
Function: Alternative housing option that allows comparison of material effects on survival and food preservation.
Example: Plastic "Puzzle" cages were tested alongside wooden cages.
Function: Solid food source suitable for mailing; less messy than liquid foods but potentially less nutritious.
Example: Prepared by mixing semi-crystallized honey and powdered sucrose in approximately 1:4 weight ratio.
Function: Natural food source that provides complete nutrition; may require special precautions to prevent disease transmission.
Example: Honey from apiaries free of American foulbrood was used in the study.
The research exploring cage types, feeding methods, and attendant workers for holding virgin honey bee queens has provided valuable insights with immediate practical applications for beekeepers and researchers alike. The discovery that wooden cages with honey and five attendant workers can maintain 100% survival for seven days represents a significant advance in queen management techniques 1 .
These findings underscore the complex interplay between environmental conditions, nutrition, and social factors in honey bee health. They remind us that successful beekeeping depends not only on broad management strategies but also on attention to precise details.
