1) At the temperature and humidity in Fukken Province in early summer, which is the epidemic season in this area, the <I>X. cheopis</I> under starving condition after sucking bloodd from the rat suffering from plague bacillus septicemia :<BR>a. demonstrates the highest of long term bacterial carrier in the body.<BR>b. has a vigorous desire of blood sucking.<BR>c. is markedly and highly infectious to guinea pigs.<BR>2) At the temperature of approximately 30°C, which is the midsummer temperature in this area, a sudden drop in the rate of carriers is noted among those fleas which once became plague bacillus carriers beginning from 3-4 days after starvation, and quite a good number of them lose the inf ectivity.<BR>3) The above described results are considered to be a major factor to the fact that the epidemic of plague in Fukken Province is limitted within the early summer not being extended to the midsummer or later.<BR>4) Among the fleas which had repeatedly sucked the infected blood, a fair number was found acquired the infectivity within 1-2 days.<BR>A deepest appreciation is due to the kind advice given by Dr. Tadayoshi Kasuga of the Kitasato Institute for Infectious Diseases at the time the results of this work were consolidated.
