Swarm Cell Inspection Interval Days
Screen a visit interval against the oldest observed queen-cell age and caller earliest-capping/lead assumptions; does not predict swarming or prescribe an inspection interval.
Description
An inspection timing scenario can compare the oldest observed queen cell with a supplied capping-age model.
An inspection timing scenario can compare the oldest observed queen cell with a supplied capping-age model. An intervention lead allowance shortens the remaining modeled interval.1
Screen a visit interval against the oldest observed queen-cell age and caller earliest-capping/lead assumptions; does not predict swarming or prescribe an inspection interval.
When to use Swarm Cell Inspection Interval Days
Use this tool to screen a visit interval against the oldest observed queen-cell age and caller earliest-capping/lead assumptions; does not predict swarming or prescribe an inspection interval.
Prepare the hive, sample or operating measurements and any supplied target values. Confirm units, timing and whether counts or masses refer to the same population or batch.
How to use Swarm Cell Inspection Interval Days and understand its results
- Prepare the hive, sample or operating measurements and any supplied target values. Confirm units, timing and whether counts or masses refer to the same population or batch.
- Enter observedCellAgesDays, earliestModelCappingAgeDays, inspectionLeadDays, currentVisitIntervalDays using the field table and calculation rules, then run the tool.
- Read maximumModelInspectionIntervalDays, visitIntervalMarginDays. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedCellAgesDays | Observed cell ages days | list of number | Required |
| earliestModelCappingAgeDays | Earliest model capping age days | number | Required |
| inspectionLeadDays | Inspection lead days | number | Required |
| currentVisitIntervalDays | Current visit interval days | number | Required |
Enter a nonempty list of nonnegative observed cell ages, positive earliest modeled capping age and nonnegative lead and current visit interval, all in days. Reject an already negative remaining lead window. Return maximum modeled interval and signed margin, including a negative margin when the current interval is too long.
maximumInterval = earliestCappingAge−max observedCellAge−lead; margin = maximumInterval−currentInterval Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| maximumModelInspectionIntervalDays | Maximum model inspection interval days | number |
| visitIntervalMarginDays | Visit interval margin days | number |

}Limitations and assumptions
Ages and capping assumptions are supplied. The result does not predict swarming or prescribe an inspection schedule, and it does not ensure all cells were observed.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Walk Away Split Timing Checker: Screen a caller walk-away development/mating timing scenario against a forage horizon; no natural queen-development constants, mating success or split recommendation is embedded. For a complementary task, use Drone Brood Trapping Cycle Days: Intersect caller removal/emergence windows for observed capped drone-brood cohorts; describes a timing scenario only, not a validated mite-control schedule or efficacy claim.
