A simple sampling method using a sticky board of 18×25 cm for estimationg the population of brown planthopper nymphs on rice hills was developed and the efficiency of this method was studied.When a rice hill was struck by hand three times successively, about 90% of the total catch was caught by the initial two beatings. Approximately 40% of the total nymphs which fell around the rice hill were caught by a sticky board in the standard position. A significant correlation was obtained between the catch on the sticky board and the total number of fallen nymphs. Highly significant correlation coefficients were also obtained between the partial counts in the medial 1/2〜1/4 area of a sticky board and the whole board counts, suggesting that the partial count can be substituted for the whole board count.
