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.

本文综述了蛀干昆虫对寄主植物选择机制和规律的国内外研究进展及其在森林健康评价中的应用前景，根据蛀干昆虫中次期性种类总是与亚健康和衰弱林木相伴的规律，提出了利用蛀干昆虫早期诊断和评价森林健康的思路，以蛀干昆虫种群数量与林木健康状况的相互关系为主，辅以物种间相互作用关系、环境因子等建立数学模型，定量分析和综合评价森林健康及其发展趋势。
