Popis: Removal samples from an irrigated pasture were used as a calibration technique for the D-Va.®. Plots 4 m2 were enclosed with a frame and 1 initial and 3 removal samples were taken. Equations are given for computing the population and probability of collecting an insect. For leafhopper adults, leafhopper nymphs, Orius insidiosus (Say), and corn flea beetle, Chaetocnema pulicaria Melsheimer, calibrations (m2/linear m) were 0.405, 0.328, 0.272, and 0.490, respectively.
