| Abstract: | Grassland rodents and locusts pests occurred in 1997～1998 were investigated. The results indicated that rodents and locusts had a wide distribution in all five major type grasslands, especially in alpine meadow and alpine steppe. A total of 22 506 hm2and 21 986 hm2grassland suffered from rodents and locusts damage, respectively. Predominant harmful rodents were Myospalax baileyi and Ochotona curzoniae. Predominant locusts were Chorthippus dubibius, Chorthippus j~'llasc and Angaracris rhodopa. The densities of Myospalax baileyi and Ochotona curzoniae were 3.0 and 2.5 individuals/hm2. Average density of locusts was 21 individuals/hm2. |
