- Method / resource Spring and late-summer aphid counts fit the Poisson series poorly.
- Method / resource Midsummer pea aphid populations were very low and closely fit the Poisson series.
- Method / resource Spring, late-summer, and midnight aphid samples generally fit the negative binomial series.
- Method / resource Omitting one or two stems with unusually high aphid counts improved negative binomial fit.
