Abstract： Investigation, monitoring, forecast and integrated management of several whitefly pests, including Bemisia tabaci(Gennadius), Trialeurodes vaporariorum(Westwood), Aleurocanthus spiniferus(Quaintance) and Pealius mori(Takahashi) and Aleurocybotus indicus(David et subramaniam), weres carried out in south, southeast, north, southwest and central China. The results indicate that Bemisia tabaci has been recorded in more than 20 provinces and the other species are distributed as follows; Trialeurodes vaporariorum in north and southwest China, Aleurocanthus spiniferus in south, southeast, and southwest China, Pealius mori in south China and Aleurocybotus indicus in eastern Fujian Province. The identification of the Q and B biotypes of B. tabaci using mt COI DNA sequencing, SCAR and CAPS methods revealed that the Q biotype is increasing its range and has displaced the B biotype in several regions. Suitable habitat, northern overwintering boundary and the number of generations in different regions were forecast using the Maxent model and GIS technology. The results of chemical resistance detection indicate that abamectin and nitenpyram are the best pesticides for the control of B. tabaci, which is more resistant to bifenthrin, thiamethoxam, acetamiprid and imidacloprid. The relative effectiveness of controlling whiteflies using abutilon plants and yellow sticky traps, insect natural enemies and spraying entomopathogenic fungal pesticides, was investigated and methods and strategies of integrated management proposed. Twelve bases were established for the technological demonstration of integrated whitefly management in South, North, Central, Southeast and Southwest China. During these demonstrations, more than 124 thousand technical handbooks were delivered and 54.3 thousand farmers trained on 4 300 hm2 of farms and orchards. This program had obvious economic, ecological and social benefits.
