Host races in the larch
budmoth Zeiraphera diniana
We have been investigating distinct "host races"
of a forest pest, the larch budmoth Zeiraphera
diniana. Each host race feeds on a different coniferous tree species,
and the races appear to be in the process of speciation. Igor Emelianov,
Michele Drès and I are estimating the rate of gene flow between the host
races, and mapping genetic loci which keep the two forms separate and are therefore,
in a sense, genes for speciation.
