The control effectiveness of combinations of biocontrol and rodenticide on plateau pika in the Northern Tibetan Plateau

A series of experiment was conducted to determine the effect of the combinations of different control measures on plateau pika (Ochotona curzoniae) in the Northern Tibetan plateau, and these control measure included perches treatment, the combination of Zhaoyingling rodenticide and perches treatment, and the combination of botulinum D toxin and perches treatment. The optimal concentration of botulinum D toxin for control plateau pika was selected by different concentration treatments, and the control effectiveness of 0.10% botulinum D toxin and Zhaoyingling rodenticide on plateau pika was compared in this study. This study showed that the control effectivenesses of 0.10% and 0.15% of botulinum D toxin were not significant differences but significant higher than that of 0.05% of botulinum D toxin. The control effectiveness of 0.10% botulinum D toxin was better than that of Zhaoyingling rodenticide. The control effectiveness of the combination of 0.10% botulinum D toxin and perches was the best, and this study suggested that the combination of 0.10% botulinum D toxin and perches could be applied into control plateau pika in the future.
