Abstract

Attributes of pest species like host range are frequently reported as being evolutionarily constrained and showing phylogenetic signal. Because these attributes in turn could influence the abundance and impact of species, phylogenetic information could be useful in predicting the likely status of pests. In this study, we used regional (China) and global datasets to investigate phylogenetic patterns in occurrence patterns and host ranges of spider mites, which constitute a pest group of many cropping systems worldwide. We found significant phylogenetic signals in relative abundance and distribution range both at the regional and global scales. Relative abundance and range size of spider mite were positively correlated with host range, although these correlations became weaker after controlling for phylogeny. The results suggest that pest impacts are evolutionarily constrained. Information that is readily easily obtainable – including the number of known hosts and phylogenetic position of the mites – could therefore be useful in predicting future pest risk of species.
