Abstract
Pest control is still the important work to manage the grassland in West China. E. baileyi Pallas is the main rodent in Qinghai-Tibetan Plateau grassland, so population density of E. baileyi Pallas was continuously investigated from 2015 to 2016 based on the previous works of 2013 and 2014, compound poison baits effects were tested on E. baileyi Pallas. The block-open method was used to survey the population density with three repeat grids. Rapeseed oil and peanut oil was used as attractant to make compound poison, and then determine the compound poison bait effects on E. baileyi Pallas. The density was 37.12 and 35.32 individuals/hm2 in 2015 and 2016, respectively. The results showed that the average feeding rate of rapeseed oil was 76.7%, which was significantly higher than that of peanut oil with 65.12% (P<0.05). The average killing rate of poison bait without attractant was 74.68%, which was significantly lower than the rate of poison bait with attractant (88.85%, P<0.01). The average density of E. baileyi Pallas in Hongyuan County was 36.22 individuals/hm2 which indicated that the pest was highly harmful to the grassland. The effect of D-type kreotoxin poisoning E. baileyi Pallas could be significantly improved with the attractant.
