Abstract

Studies of dispersal of Podisus maculiventris (Say) nymphs in immature soybeans revealed that they tended to disperse along rows rather than across rows. Sampling these nymphs 1 and 2 days post-release provided data which fitted the equation, Y = a + b Log x + c/x , where Y = density, x = distance from the release point, a = intercept, b = slope, and c = a proportionality constant. Results from samples obtained 4 and 7 days post-release did not provide good fits to the same equation.
