The paper reviewed the host selection mechanisms and rules of xylophagous insects and their application foreground in forest health evaluation. According to the rule that some secondary xylophagous insects always accompany with trees which are sub-healthy or unhealthy, ideas of diagnosing and evaluating forest health betimes using xylophagous insects were posed. Mathematical models would be established based mainly on interactions between quantity of xylophagous insect populations and status of forest health, interspecific interactions (community structure, biodiversity) and environmental factors were also added as supplementary parameters, in order to quantitatively analyzing and comprehensively evaluating forest health and its developing trend.
