Research Abstract

The details of evolutionary process of host-range expansion by phytophagous beetles are largely unknown. In this research project, I hypothesized that the utilization of subsidiary host plants by adult beetles provides potential ability of larvae to develop on the novel hosts, and tried to test this hypothesis by field surveys and several laboratory experiments. Although only a part of results supported the hypothesis, it was suggested that the ability of larvae to develop on a potential host could be conferre by very rare utilization of the host by adults, and the hypothesis would be supported only for adults' and larval survival on a particular host.
