Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.

取食构树的桑天牛成虫取食量大，存活时间长，产卵量大，遗卵量少，其他3个树种则相反。4树种树皮内总糖和可溶性蛋白含量与桑天牛抗性无关，树皮内可溶性糖含量、总氨基酸和必需氨基酸含量对抗性有一定影响。4树种树皮内水溶性总酚含量和单宁含量差异对成虫取食有较大影响，酚类和单宁等次生物质对桑天牛成虫的忌避作用是导致抗性的主要原因。
