Determination of damage yield loss relationships and economic injury levels of Oedaleus asiaticus (Orthoptera: Acrididae) in steppe of China

摘要：

Previous studies reported that Oedaleus asiaticus is the common and dominant grasshopper of Xilingol grassland, in Inner Mongolia, China.( Lu et al., 2005 ).O.asiaticu occurs every growing season and results in yield losses through premature dropping of grass.Grain yield losses have also been reported for grasshoppers on grassland from different areas of China (Qiu et al., 2004 ).Study was to establish the relationship between Oedaleus asiaticus populations and yield loss of grass, and determine EILs for Oedaleus asiaticus in steppe.
