Leaves of red oak trees that had been defoliated by gypsy moth larvae during the previous year and again during the period of the study had higher values of tanning coefficients, total phenolics, hydrolyzable and condensed tannins, dry matter contents, and toughness than did leaves of undamaged trees. These changes may influence larval growth and alter the course of further outbreaks.
前一年和研究期间被舞毒蛾幼虫取食过的红橡树的叶子比未受损树木的叶子具有更高的鞣酸系数、总酚类、可水解和缩合单宁、干物质含量和韧性。这些变化可能会影响幼虫的生长并改变进一步爆发的进程。
