✦ Synopsis

We investigated relationships between host plant hybridization in the Quercus grisea x Q. gambelii species complex and the distribution and performance of a leaf-mining moth in the genus Phyllonorycter. In 2 years at two sites Phyllonorycter densities were lowest on Q. grisea and increased through the categories of hybrid host plants to Q. gambelii. Direct host plant effects on Phyllonorycter performance were consistent with Phyllonorycter distribution; unexplained mortality of larvae in the mines, which is often associated with direct plant effects, decreased from Q. grisea through the hybrids to Q. gambelii. Plant hybridization influenced parasitism of Phyllonorycter. Parasitism was density dependent, and across all densities was higher on Q. grisea and Q. gambelii than on hybrid host plants.

In recent years an increasing amount of information leaves no doubt that the costs to the victims of plant closures are more than economic. The stress occasioned by job loss often results in ill health. These findings aside, little systematic research has been done of the consequences of unemploymen
