Summary

  • • 
    Metal hyperaccumulation has been proposed as a plant defensive strategy. Here, we investigated whether cadmium (Cd) hyperaccumulation protected Thlaspi caerulescens from leaf feeding damage by thrips (Frankliniella occidentalis).
  • • 
    Two ecotypes differing in Cd accumulation, Ganges (high) and Prayon (low), were grown in compost amended with 0–1000 mg Cd kg−1 in two experiments under glasshouse conditions. F2 and F3 plants from the Prayon × Ganges crosses were grown with 5 mg Cd kg−1. Plants were naturally colonized by thrips and the leaf feeding damage index (LFDI) was assessed.
  • • 
    The LFDI decreased significantly with increasing Cd in both ecotypes, and correlated with shoot Cd concentration in a log-linear fashion. Prayon was more attractive to thrips than Ganges, but the ecotypic difference in the LFDI was largely accounted for by the shoot Cd concentration. In the F2 and F3 plants, the LFDI correlated significantly and negatively with shoot Cd, but not with shoot zinc (Zn) or sulphur (S) concentrations.
  • • 
    We conclude that Cd hyperaccumulation deters thrips from feeding on T. caerulescens leaves, which may offer an adaptive benefit to the plant.
