	abstract = {Numerous groups of herbivorous insects in the Hawaiian archipelago have undergone adaptive radiations. RCL Perkins collected and documented species in nearly all of these groups. In this study I tested whether patterns of host plant use by herbivoreous insects can be explained by host plant history. I examined a group of insects in the planthopper genus Nesosydne (Hemiptera: Delphacidae) that feed on plants in the Hawaiian silversword alliance, many of which are endangered or threatened. For these Nesosydne species feeding on the silversword alliance, mitochondrial DNA sequence data revealed a statistically significant pattern of cospeciation between these insects and their hosts. These planthoppers are highly host-specific, with each species feeding on only one, or a few closely related, plant species. Patterns of host plant use across th plant lineage, as well as within extensive hybrid zones between members of the silversword alliance, suggest that planthopper diversification parallels host plant diversification. Data collected thus far are consistent with, but do not directly demonstrate, reciprocal adaptation. For other herbivorous insects associated with members of the Hawaiian silversword alliance, patterns of host plant use and evolutionary history are not yet well understood. However, cospeciation appears not to be universal. For example, endemic flies in the family Tephritidae (Diptera) are less host-specific and demonstrate host-switching. Research is under way to reveal the mechanisms associated wih cospeciation and host-switching for different insect groups associated with the Hawaiian silversword alliance.},

	abstract = {Many advances in the understanding of insect-plant interactions have come from examining particular taxa or systems in isolation. Here, we examine the contribution of studies on remote oceanic islands to our understanding of insect-plant interactions. For ecological and evolutionary studies, island systems offer a number of advantages that stem from their isolation, small size, well-defined boundaries, and that they can be used as replicate systems. Unlike recent introductions to islands where many of the insect herbivores show generalist associations, among indigenous species the majority are endemic and show varying levels of host specialization. We examine patterns of of host specialization, plant-associated diversification, cospeciation, symbiosis, and plant hybridization across a range of island systems, though most work to date has focused on the Macaronesian Islands and the Hawaiian archipelago. Advances in molecular and analytical approaches have opened new avenues for research, such as the ability to calibrate the ages of both insect and plant lineages and to examine the demographic history of individuals within populations. Island insect-plant systems illustrate that allopatric isolation in particular, but also host switching to related hosts, are important correlates of insect diversification. Observations of cospeciation are rare, but this may be a consequence of studying periods of rapid host adaptation and diversification in which patterns of cospeciation, if they exist, may be obscured. Island systems offer many opportunities to expand our understanding of factors that promote host-associated diversification, including the roles of internal and external symbionts and plant hybrids.},

Thirty individuals from one population and 10 individuals from two populations across the species{\textquoteright} range were tested to investigate polymorphism. The observed loci contained two to nine alleles per locus. Expected heterozygosity within this species ranged from 0.2 to 0.85. These markers will be used to assess intraspecific differentiation and population structure within N. chambersi.},
