Abstract
Experiments were carried out in areas of Yangzhou, Nanjing and Zhenjiang in Jiangtsu Province in 1979-1984. Results showed that alate aphids were the major vectors of SMV transmission and apterous aphids had no relation to the epidemic of SMV in the field. Alate aphids were collected by yellow -pan water traps and apterous aphids were quantified by observations on soybean plants. Predominant spec ies of alate aphids transmitting SMV were Myzus persicae, Aphis craccivora and Rhopalosiphum pseudobrassicae. Species, number of aphids, and landing date varied considerably in differents area and from year to year. During the aphid flight activity period, the younger the soybean plants, the more severe the disease. Non-persistent insecticides used against aphids in soybean fields provided no significant effect on SMV disease control.
