. 1 The oak treehopper Platycotis vittata (Fabricius) is bivoltine throughout its range with discrete generations in the early spring and autumn. Females of both generations diapause. 2 Latitudinal variation in the timing of life history exists among four populations of P. vittata along the eastern coastal plain of the United States. 3 We disrupted synchronization between P.vittata life history and host-plant phenology in the springs of 1984 and 1985 by placing southern populations… CONTINUE READING
