Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(2012) In Bulletin of Entomological Research 102. p.149-155- Abstract
- In the interaction between two ecologically-associated species, the population
structure of one species may affect the population structure of the other. Here, we
examine the population structures of the aphid Metopeurum fuscoviride, a specialist on
tansy Tanacetum vulgare, and its specialist primary hymenopterous parasitoid
Lysiphlebus hirticornis, both of which are characterized by multivoltine life histories
and a classic metapopulation structure. Samples of the aphid host and the parasitoid
were collected from eight sites in and around Jena, Germany, where both insect
species co-occur, and then were genotyped using suites of polymorphic microsatellite
markers. The... (More) - In the interaction between two ecologically-associated species, the population

were collected from eight sites in and around Jena, Germany, where both insect
species co-occur, and then were genotyped using suites of polymorphic microsatellite
markers. The host aphid was greatly differentiated in terms of its spatial population
genetic patterning, while the parasitoid was, in comparison, only moderately
differentiated. There was a positive Mantel test correlation between pairwise shared
allele distance (DAS) of the host and parasitoid, i.e. if host subpopulation samples
were more similar between two particular sites, so were the parasitoid subpopulation
samples. We argue that while the differences in the levels of genetic differentiation
are due to the differences in the biology of the species, the correlations between host
and parasitoid are indicative of dependence of the parasitoid population structure on
that of its aphid host. The parasitoid is genetically tracking behind the aphid host, as
can be expected in a classic metapopulation structure where host persistence depends
on a delay between host and parasitoid colonization of the patch. The results may also
have relevance to the Red Queen hypothesis, whereupon in the ‘arms race’ between
parasitoid and its host, the latter ‘attempts’ to evolve away from the former. (Less)
