Which sampling method would you use to collect insects from vegetation by beating the plants and catching insects on a sheet?

• A. Beat sheet sampling
• B. Sweep net sampling
• C. Pitfall trapping
• D. Aerial netting

Answer: (A)

Beat sheet sampling is used to dislodge insects from vegetation by beating the plants and catching them on a sheet. You place a light-colored sheet under the plants, strike the foliage with a stick, and the insects fall onto the sheet for counting and collection. This method is especially good for insects that live on leaves and stems and are easily knocked off, such as many foliar feeders on shrubs or herbaceous vegetation. Sweep net sampling, in contrast, gathers insects by sweeping a net through vegetation, catching those that are in motion or resting in grasses and similar habitats. Pitfall trapping targets ground-dwelling insects that fall into a buried container. Aerial netting captures flying insects in the air, not those dislodged onto a sheet from the vegetation.
