The shortest period for acquisition feeding of potato leaf roll virus by green peach aphid (Myzus persicae Sulzer) from infected potato or Datura stramonium L. plants was 5 to 10 minutes. Viruliferous aphids transmitted the virus to healthy Physalis floridana Ridb. plants by inoculation feeding of at least 5 minutes. The transmission threshold period of potato leaf roll virus in aphids was 16-24 hours in room temperature, but latent period after acquisition feeding of l,4 and 8 hours was found to be 23-24, 12-16 and 8-16 hours, respectively, and also it differed with infection source plants. The results of experiments on the effects of temperature on infectivity indicated that the aphids were more transmissible at high temperature (30°C) than low one (15 and 22°C). The shortest latent period was found to be 72 hours at 15°C, 16 hours at 20°C and 8 hours at 25-30°C, respectively. It indicated that there was correlation between temperature and length of latent period in the aphid vector. (Received October 14, 1969)
