Mutualistic interactions are ubiquitous in nature. These type of interactions generally provide benefits to interacting species. Insects and plants are commonly involved in diverse forms of mutualism, however little is known if genetic variation among plants allows for a positive symbiosis with arthropods. In this study, we investigated whether plant traits in Boechera stricta (Brassicaceae) play a role in arthropod recruitment, and if so, whether the genetic basis of the plant contribute to this interaction. We also addressed whether visitation by ants and other insects minimized herbivory. We established a common garden experiment in which insect visitation to B. stricta was observed. We assessed insect visitation and herbivory on >400 known genotypes, as well as other plant traits. Within plant characteristics (number of flowers and fruits), plant height had a predominantly positive effect on the abundance of arthropods. Overall, plant height led to higher insect visitation, but the abundance of ants and other insects had no effect on herbivory due low insect observations and insufficient statistical power. Furthermore, we found a significance in the genetic basis of ant recruitment. These results indicate ant visitation can be influenced by plant traits, yet further studies are needed to determine what specific genes underlie in these traits.
