Earwigs are often abundant in orchards. This research will increase our understanding of the biocontrol potential of this predator. The study will assess the extent to which earwigs consume pest species such as aphids. It will enable us to determine if the diet changes over the season and whether any changes are preferences of the predator or simply the result of availability of prey species. The information obtained will enable us to assess the potential usefulness of earwigs in helping to suppress pests.
