During the syrup feeding on July 21, several key observations were made. A ½ gallon of 1:1 sucrose syrup was fed to the colonies as part of the third feeding. A spot check showed that most colonies had drawn a few frames of foundation in the second box, though not all had done so. Notably, very little beebread was found in the combs, signaling that the trial should conclude. This lack of beebread, combined with the progress in foundation drawing, indicated the colonies' nutritional and developmental state at that time.
Key Points Explained:
-
Syrup Feeding Details
- Quantity & Type: Each colony received ½ gallon of 1:1 sucrose syrup. This ratio is common for stimulating brood rearing and comb building.
- Timing: This was the third feeding, suggesting prior feedings had occurred (e.g., July 7), with the nectar flow tapering off by then.
-
Colony Progress Assessment
- Foundation Drawing: Most colonies had drawn "a few frames of foundation in the second box," indicating comb-building activity. However, the inconsistency ("not all") hints at variability in colony strength or resource allocation.
- Beebread Scarcity: The minimal beebread (stored pollen) suggested dwindling pollen supplies, critical for brood nutrition. This scarcity was a decisive factor in ending the trial.
-
Trial Conclusion Rationale
- The lack of beebread implied colonies might struggle to sustain brood without supplemental pollen, risking colony health.
- Combined with the comb-building progress, the data provided a clear endpoint for the trial’s objectives.
-
Context from Prior Observations
- Earlier feedings (e.g., July 7) showed adequate pollen stores ("four colors of pollen"), highlighting a decline by July 21.
- Equipment limitations (e.g., honeycomb-clogged rims) noted earlier may have influenced colony dynamics.
-
Implications for Beekeepers
- Monitoring: Regular checks for beebread levels are vital to gauge colony nutrition.
- Intervention Timing: The observations underscore the need to adjust feeding or pollen supplementation before stores deplete.
This structured approach ensures clarity for equipment or consumable purchasers, linking observations to actionable insights for hive management.
Summary Table:
| Observation | Details | Implications |
|---|---|---|
| Syrup Feeding | ½ gallon of 1:1 sucrose syrup per colony (third feeding) | Stimulates brood rearing and comb building; timing aligns with nectar flow taper. |
| Foundation Drawing | Most colonies drew a few frames in the second box; some lagged. | Variability in colony strength or resource allocation. |
| Beebread Scarcity | Minimal stored pollen found in combs. | Indicates dwindling pollen supplies, risking brood nutrition; trial endpoint. |
| Trial Conclusion Rationale | Lack of beebread + comb progress = clear endpoint for objectives. | Prevents colony health risks due to nutritional deficits. |
