文摘内容 The result of integrated control against Otidognathus rubriceps was reported in the paper. Spraying the bamboo at 9～10 am. during the peak of the adult who oviposited going up to the bamboo, adopting the 20% of the emulsifiable solution of fenvalerate 1000 time'solution, spraying again after 5 days, the control effect was higher than 90 percent. The highest rate of infecting the larva with insect's pathogenic nematode in lab was Steinernema carpocapsae Beijing, the corrected mortality was 51.35% after 10 days when it was treated. The control effect reached 42.56～66.08% if it was sprayed by different strains of nematodes in the dosage of 2 x 105 ~m-2 on the ground of forest. Beauveria bassiana had a poor infected effect on the larva,which is 32.43% of corrected mortality after 15 days. Spraying the power of B. bass/ana on the ground before the larva going down could reduce the new bamboo's injured rate by 12.52% the next year, and reached 29.21% of control effect. Shaking the tips before the peak of the larva going down could reduce the hibernating population, the control effect reached 89.44%. The adult was caught by manual, comparing with the comparative stand, the injuring rate of the one-year-old bamboo declined by 43.74% and the control effect was 64.50%. Reclaiming the land deeply had a certain effect on Otidognathus rubriceps in winter, but it was better doing it after the larva going down (in the middle of May), the injuring rate of the one-year-old bamboo descented by 60.00%, and control effect was 87.84%。
