Indirect genetic benefits derived from female mate choice comprise
additive (good genes) and non-additive genetic benefits (genetic
compatibility). Although good genes can be revealed by condition-dependent
display traits, the mechanism by which compatibility alleles are detected
is unclear because evaluation of the genetic similarity of a prospective
mate requires the female to assess the genotype of the male and compare it
to her own. Cuticular hydrocarbons (CHCs), lipids coating the exoskeleton
of most insects, influence female mate choice in a number of species and
offer a way for females to assess genetic similarity of prospective mates.
Here, we determine whether female mate choice in decorated crickets is
based on male CHCs, and whether it is influenced by females’ own CHC
profiles. We used multivariate selection analysis to estimate the strength
and form of selection acting on male CHCs through female mate choice, and
employed different measures of multivariate dissimilarity to determine
whether a female's preference for male CHCs is based on similarity to
her own CHC profile. Female mating preferences were significantly
influenced by CHC profiles of males. Male CHC attractiveness was not,
however, contingent on the CHC profile of the choosing female, as certain
male CHC phenotypes were equally attractive to most females, evidenced by
significant linear and stabilizing selection gradients. These results
suggest that additive, rather than non-additive genetic benefits accrue to
female mate choice, in support of earlier work showing that CHC expression
of males, but not females, are condition dependent.
