Percentage of predicted pecky rice damage fitted by the extended model that represents the sensitivity of the model prediction. The lowest (Semine region in 2018, blue dotted lines) and highest (Maesawa region in 2011, red and pink solid lines) risk cases are demonstrated. The fitted values were calculated using the minimum, average, and maximum areas of source habitat (0.37, 3.12, and 8.32 ha, respectively) and soybean fields (0, 0.33, 2.90 ha, respectively), and the average area of rice paddy fields (9.42 ha). Circles, triangles, and squares indicate the minimum, average, and maximum areas of source habitat. The background color of the graph indicates the grades of pecky rice damage
