The results showed that the rate of mating disruption was 71.1%-80.7% caused by 150-750 rubber pheromone dispersers per hm 2. The egg numbers were reduced by 79.4%-86.1%, 72.9%-84.7%, 58.3%-65.1% and 58 9% at the treatments of 750, 300-375, 120-150 and 30 rubber dispersers per hm 2, respectively. In large scale disruption demonstrations, numbers of egg masses decreased 82.4% and 73.2% at placements of 60 dispersers per hm 2 in mid season rice seeding paddy and in early season transplanting paddy, respectively.

Models of space variation were constructed at the directions of east-west and south-north based on the geostatistical method by using 10 survey data from the transplanting to ripening of the rice in Xiushan, Chongqing in 2008. Isoclines maps of the WBPH nymphs at each stage were created by the geostatistical software Surfer8.0 with Kriging interpolation.
