Summary
A recent model in sexual selection has proposed a role for parasites in maintaining heritable fitness variation. Females are envisaged as benefitting from preferentially mating with males that show resistance to infection. The post-copulatory guarding behaviour characteristic of many species of field cricket, has been envisaged as a means by which females assess male health and vigour. This hypothesis was tested in a field cricket, G. bimaculatus, which harbours a protozoan gut parasite. In enclosed arena trials, no direct correlations between female behaviours and levels of infection in males were found. However, there were significant correlations between the intensity of male guarding and the number of parasites found in the gut; infected males guarded more intensely in order to maintain contact with the female. In a second experiment simulating open field conditions, females left heavily parasitized males sooner than mildly or uninfected individuals. These data are discussed in relation to female choice for male health and vigour.
