Abstract： An automatic counting system for surveying the density of Bemisia tabaci(Gennadius) adults was developed according to image recognition theory.The automatic counting method included the following steps: 1. Measure the distance between imager and image object. 2. Discriminate B. tabaci individuals from background image and count. 3. Compute the area of host plant leaves. 4. Compute the density of B.tabaci adults.This counting system was over 90% accurate.
