Spatial Distribution Pattern of Hippota dorsalis (Stal) and Its Application

Abstract: All overwintering nymphs of Hippota dorsalisobeyedaggregation distribution at different population density. The basic part ofdistribution was individual colony.The cause of aggregation was related to not only the environmental factors but also the gathering behavior of the overwintering nymphs. Two to three nymphs ofHippota dorsalisin mean up a plant were critical value of changing the aggregation system. The sample data was transformed by Iwao's transformation formulae could get a better result. In addition, with Iwao's method, the sequential sampling table of the overwintering nymphs ofHippota dorsalis was obtained and the optimum sample size was calculated.
