Experiment on three biological pesticides preventing and controlling Dendrolimus houi

Abstract: Experiment on three biological pesticides preventing and controlling 3 -4 instar larva of Dendrolimus houi including Ludebao , Bacillus thuringiensis (Bt)and Aveyjunsu was conducted .The results indicated that the effective rate of the Ludebao at the proportion of 1∶10 , 1∶15 and 1∶20 all reached over 84.97 %.Ludebao at the proportion of 1∶15 was suitable for preventing and controlling D .houi within the vast area of the forest .The effective rate of Aveyjunsu at the proportion of 1∶4 000 was up to 93.23 %, which was suitable for preventing and controlling D .houi within a small area with sufficient water source and short trees or around houses .[ Ch , 1 tab . 7 ref .]
