| 摘 要： | 在系统地研究柏木鲜叶量，鞭角华扁叶蜂幼虫种群食叶量及各虫态种群数量幼态变动的基础上，利用柏木的失叶量2估计鞭角华扁叶蜂入土老熟幼虫虫口密密，进而预测来年的发生量，结果表明，利用柏木失叶量预测发生量，预测准确达90％。

| Abstract: | On studying the relations between the fresh leaf amount of Cupressus funebris and leaf damaged by larva of Cephalcia flagellicornis and variation of population amount of different stage of larva, the leaf loss of Cupressus funebris could estimate the insect density of underground matured larva of Cephalcia flagellicornis for forecasting the next year occuring. It shows the accuracy ratio for 90%. |
