Abstract

Red clover (Trifolium pratense) has been observed to persist longer than white clover (T repens) during field screening of legumes for tolerance of clover root weevil (Sitona lepidus) It has been suggested that this is linked to adult feeding preferences A laboratory trial was undertaken to confirm the feeding preference for white clover over red and to determine whether adults became habituated to red clover over time Groups of clover root weevil adults were caged on either white clover cv Grasslands Huia or 3 lines of Grasslands Pawera red clover At weeks 2 4 6 and 8 subsamples of adults were removed from the cages and were subjected to a 24 h choice test It was found that although adults showed a strong preference for white clover those that had been continuously fed red clover were more likely to feed on red clover in the choice test than those that had previously been fed white clover
