The silvicultural, chemical and biological measures were employed respectively to control the larva ofKumasia kumaso (Sugi) of Acidosasa edulis. :The silvicultural measures mainly included weeding & deeply bury-ing, weeding combined with burning , weeding & deeply burying combined with DDVP. And the biological measuresincluded spraying with two kinds of B. t (made respectively in Jianou and Fuqing), Bacillust huringiensis (16000IU/mg), AcNPV etc. And the chemical measures included spraying with 80% DDVP E. C, 40% Omethoate E. C,Shachongguang or Lindane 1:500 × and 1: 1000 × in 1999, and 17.5% Imidan E.C, 5% Cypermethrin E.C,20 % Fenpropathrin E. C, 20 % Baibusi E. C 1: 800 × and 1: 1500 × in 2000. the results showed as follow:1. In silvicultural measures, different treatments have no remarkable influence on the experiment results, but it canimprove the hygienic condition.2. In biological measures , different treatments have no remarkable influence on the experiment results.3. In chemical measures, 1: 500 of Lindane was adapted to eliminate the larva in the mother shoots with the deathratio amounting to 91.10% What' smore, 20% Fenpropathrin E. C 1: 800 × , 5% Cypermethrin E. C 1: 800 × ,20% Baibusi E. C 1: 800 × are also adapted to generalize in forestry with the death ratio amounting to 92.09%,76.81%, 75.74 % respectively.
