We investigate the possibility that the presence of terrestrial planets could affect the volatile\u2010to\u2010refractory abundance ratios. Stars with and without planets exhibit very similar abundance behaviours, either for solar twins or even when considering the whole sample of 95 solar analogs, 33 with and 62 without detected planets, in the metallicity range \u20130.3 &lt; [Fe\/H] &lt; 0.5. After removing the Galactic chemical evolution effects, the small differences in the abundance patterns of stars with and without planets practically disappear and the mean volatile\u2010to\u2010refractory abundance ratios of the two samples are very close to solar values. If the depletion signature depends on the size of the convective zone, then stars hotter than the Sun should, in principle, show enhanced volatile\u2010to\u2010refractory abundance differences. Thus, we have also selected a sample of late F\u2010 and early G\u2010type main\u2010sequence stars with high\u2010quality spectra. We have in total 29 planet\u2010host stars and 32 stars without planets in the <jats:italic>T<\/jats:italic><jats:sub>eff<\/jats:sub> range 5950\u20136400 K. We find very accurate Galactic chemical trends of these hotter stars that match those of solar analogs. Finally, we compare the abundance ratios of volatile and refractory elements versus the condensation temperature of this sample of main\u2010sequence stars hotter than the Sun with respect to those of solar analogs, paying special attention to those stars containing super\u2010Earth\u2010like planets.
