摘要
以卷叶数作为长鞘卷叶甲Leptispa longipennis(Gestro)的危害量,人工剪枝叶模拟该虫危害,建立产量与失叶率的回归模型,并经计算确定了长鞘卷叶甲的防治指标为277.095头/丛。
Taking the number of rolled leaves as the infestation quantity of Leptispa longipennis and stimulating its damage by artificial pruning, the regression model between the yield and defoliation rate was established and the control index of L. longipennis was determined as 277.095 beetles per clump.
