Biological Control of Cenopalpus lineola in Mountain Huangshan Scenic Spot by Paecilomyces cateniannulatus
An experiment was conducted to control Cenopalpus lineola, which do harm to Pinus taiwanensis, by Paecilomyces cateniannulatus. Results show that P. cateniannulatus has a strong virulence to C. lineola and has great development potential. The virulence of P. cateniannulatus was affected by spore density in suspension solution, host instars and acting time. The corrected accumulative mortality increased with the prolonged time. The median lethal time decreased with increasing spore density at the same larval instar, and the death rate of the larva increased with decreasing larval instar at the same spore density. Therefore, more attention should be paid to the control of the second instar larvae of C. lineola in practice.
