Three sampling methods—sweep-net, hand-vacuum modified from a leaf vacuum/blower, and a wheeled, blower-vacuum designed to blow insects from the foliage into the vacuum port of a leaf vacuum—were compared as methods for sampling insects in sweetpotatoes, Ipomoea batatas L. Results of the 4-yr study at 2 locations in Mississippi showed that the number of insects collected by the blower-vacuum method was lower than the number collected by the other 2 methods. Although results differed with different insect species, the numbers of insects collected in hand-vacuum samples were usually greater than or equal to those collected in sweep-net samples during the first few weeks after planting, but less than those in sweep-net samples late in the season. Based upon these results, sweep-nets are the preferred method for season-long sampling of insects in sweetpotatoes.
