However, attempts to document demic adaptation in natural populations of scale insects have yielded conflicting results (Wainhouse and Howell 1983; Unruh and Luck 1987; Cobb and Whitham 1

Thus, to thoroughly understand both the conditions that favor the evolution of local adaptations in phytophagous insects and the scale at which those adaptations occur, it is essential to elucidat

Deme Formation in a Dispersive Gall-Forming Midgedmunds and Alstad 1978). If some herbivore genotypes have advantages over others on particular hosts, and this variation is heritable over time, then these isolated populations, or demes, should diverge from the parent population and become reproductively isolated.
