Abstract:: Taking pepper planting base of Regiment 21 Division No.2 of Xinjiang Production and Const Ruction Group as research object,the timing fixed-point investigation was used to investigate the occurrence law of pepper virus disease and the effects of climatic conditions，aphid on pepper virus disease in Yanqi reclamation region of Xinjiang.The results showed that the pepper virus disease occurred from late May,and developed rapidly from late June to late July,and reached to the peak from early August to late September.It was advantageous to the pepper virus disease when the average temperature was 20-25℃.High rainfall in the incidence rapidly expanding period would inhibit the number of aphids and inhibit the occurrence of virus disease.The accumulative rainfall was positively correlated with the virus disease.The occurrence peak of aphids coincided basically with the rapid development period of disease.Aphids were important transmission mediators of pepper virus disease in Yanqi reclamation region.When spraying the 400 times liquid of 6% oligosaccharides at the beginning of virus disease occurrence，the defensive efficiency could reach 80.16% two weeks after the second spraying，and it did not produce the phytotoxicity.Oligosaccharides was better obviously than the other three pesticides，which could be recommended to use in prevent and control of pepper virus disease.
