Seasonal Patterns in the Adult Population of Pine Spittlebug, Aphrophora flavipes(Homoptera : Cercopidae), with Special Attention to the Dispersal during the Reproductive Period

Description
Adult populations of the pine spittlebug, Aphrophora flavipes were studied by individual marking, release and recapture technique at three study plots in the University Forest Experiment Station at Tanashi in 1984. The population sizes and survival rates were estimated by the JOLLY-SEBER method and seasonal fluctuation patterns were compared among the plots. The species had a relatively long adult life span : 20-30 days on average and a little over four months at maximum for both sexes. Females made up about 70% of the total population and the sex ratio was constant throughout the seasons. Dispersal and mating activities both increased in autumn. Also in autumn, the population at each plot, containing a high proportion of immigrants, fluctuated in size, possibly as a result of the balance between immigration and emigration.
