True or False: The number of samples needed per field varies with field size and pest, with larger fields generally requiring more samples to get an accurate estimate.

• A. True
• B. False
• C. Not sure
• D. Depends

Answer: (A)

When you’re estimating pest levels, you plan the sampling to achieve a certain precision. Larger fields introduce more area to cover and often more variation in pest presence or density, so a bigger set of sampling points is usually needed to get an accurate picture. More samples help reduce sampling error and give you a confidence interval narrow enough to make reliable decisions about whether to treat. Pest distribution matters too: if pests are clustered or highly variable, you’ll need more samples to detect those patterns across the field. If pests were perfectly uniform and easy to spot everywhere, you might get away with fewer samples, but that’s not the typical case in real fields. So the statement is true: larger fields generally require more samples to produce an accurate estimate. The other options don’t fit because a fixed sample count across all field sizes ignores field-to-field variability, and while there are scenarios where the exact number depends on specific pest behavior, the general rule is that bigger fields demand more sampling.
