Experimental report of the Shi-Shuang-Shu-Ba on the prevention and control effect of Rhombomys opimus in natural Haloxylon ammodendron forests in Ulat Hou Banner
In recent years,the Rhombomys opimus in natural Haloxylon ammodendron forest region of Inner Mongolia caused serious damage to local habitats.By digging caves and eating high-quality forage,they had caused a large amount of soil and water loss in the grassland,and the productivity of the grassland and the live-stock carrying capacity of the grassland decreased seriously.At the same time,Rhombomys opimus are also carri-ers and disseminators of yersinia pestis,which is a potential hazard to human health.Therefore,the grassland station of the Ulat Hou banner utilized biological control technology and conducted rodent control trials by using the Shi-Shuang-Shu-Ba ecological rodenticide.The results showed that the Shi-Shuang-Shu-Ba rodenticide had significant effects in the prevention and control of Rhombomys opimus,the rodents effective hole extinction rate was up to 55%,the poisonous bait feeding rate was up to 75%within 5 days and the average feeding rate was 60%.Shi-Shuang-Shu-Ba rodenticide had good palatability,no environmental pollution and no poisoning deaths of non-target were detected.Therefore,Shi-Shuang-Shu-Ba ecological rodenticide can be widely used for rodent control work in this region.
