Small Hive Beetle Trap Threshold Checker
Actual trap-exposure-normalized small hive beetle observations vs caller independently applicable monitoring threshold; no population extrapolation or control recommendation. Caller independently verifies strain, site, protocol and evidence; not colony-health, treatment, transport-safety or regulatory certification.
Description
Trap counts need matched observation durations to express beetles per trap-day.
Trap counts need matched observation durations to express beetles per trap-day.1
A monitoring threshold does not identify population size or establish a treatment prescription. Use Small Hive Beetle Trap Threshold Checker to evaluate the supplied inputs under the model explained below.
When to use Small Hive Beetle Trap Threshold Checker
Use Small Hive Beetle Trap Threshold Checker to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Small Hive Beetle Trap Threshold Checker and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed trap beetle counts, Observed matched trap days, Caller beetles per trap day threshold using the field table and validation rules below, then run the tool.
- Read Pooled beetles per trap day, Caller monitoring threshold reached; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedTrapBeetleCounts | Observed trap beetle counts | array of number | Required; constraints below |
| observedMatchedTrapDays | Observed matched trap days | array of number | Required; constraints below |
| callerBeetlesPerTrapDayThreshold | Caller beetles per trap day threshold | number | Required; constraints below |
Enter nonempty aligned nonnegative safe-integer beetle counts and positive matched trap-days, plus a nonnegative caller rate threshold. Divide pooled counts by pooled trap-days and compare inclusively. No threshold, diagnosis, treatment or unobserved trap efficiency is inferred.
beetlesPerTrapDay=Σcounts/ΣtrapDays; reached=rate≥callerThreshold Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| pooledBeetlesPerTrapDay | Pooled beetles per trap day | number |
| callerMonitoringThresholdReached | Caller monitoring threshold reached | boolean |

}Limitations and assumptions
A monitoring threshold does not identify population size or establish a treatment prescription. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
