Oedaleus decorus is a widely distributed species over the Eurasian semi-arid territories, from the Atlantic coast to the Pacific one. In many semi-arid territories, O. decorus was and is the important pest. In the south-eastern part of West Siberian Plain, until the 1960s it was not considered a pest. We compared two sets of data on the acridid distribution in the region: until the 1950s and from the 1960s until 2019. Until the 1960s the species occurred mainly in the southern steppes. Since the 1960s its distribution changed significantly. Nowadays it occupies almost all local steppes and the southern part of the forest-steppes and was also found on the eastern side of the Ob River. These shifts may be explained by both climatic changes and changes in human activities. During upsurges the densities of O. decorus were often more than 1-2 adults per square meter. It was and is often abundant in the same habitats and in the same periods as the Italian locust (Calliptamus italicus)one of the most important pest. This means during joint outbreaks these two species can simultaneously damage almost all spectrum of plants.

Oedaleus decorus is a widely distributed acridid over the Eurasian semi-arid territories, from the Atlantic coast to the Pacific coast. In many semi-arid territories, O. decorus was and is the most important pest, but in the south-eastern part of West Siberian Plain, it was not considered a pest until the 1960s. We compared two sets of data on the acridid distribution in the region: before 1960 and from 1961 until 2021. Until the 1960s, the species occurred mainly in the southern steppes. Since the 1960s, its distribution changed significantly. Nowadays, it occupies almost all local steppes and the southern part of the forest-steppes and can be also found on the eastern side of the Ob River.

“…All spiders were counted and identified to the order level, and grasshoppers were counted and identified to suborder. In addition, insects from each order were separated into guild groups based on Nonnaizab, Qi, and Li (1999) and Ma, Li, and Kang (1991) and then we determined whether they were herbivores or carnivores.…”

Arthropod pest outbreaks are becoming more common in the grasslands of Inner Mongolia, China, most likely due to the expansion of agriculture. The area of cropland has increased from 43,300 km 2 in 1949 to 76,300 km 2 in 2005. To understand the effects of agricultural activities on arthropod distribution, sweep net sampling was conducted in a natural grassland. We collected 1287 individuals belonging to 23 families and 9 orders of arthropods from 41 sites. We divided these samples into two guild types (predator and herbivore) and analyzed six groups (grasshoppers, herbivorous Coleoptera, herbivorous Hemiptera, Cicaddidae, Araneae, predatory Coleoptera) of them. Using a negative binomial regression analysis we analyzed the relationships between each group's sampled population size and measured environmental factors including pesticide application and mean temperature of the previous year, agricultural site, and vegetation condition. The best model for each group was determined using Akaike's information criterion. Grasshoppers showed a significant positive response to pesticide application and degraded vegetation, whereas spider (natural enemies of some insect pests) showed a negative response to these factors. The population of grasshoppers increased at sites where pesticides were applied, vegetation was degraded, and spider numbers were reduced. Other groups were not significantly correlated with pesticide application and degraded vegetation. Some of the environmental factors we studied promoted pests the following year. Our results also suggest that the current use of pesticides may not be effective for pest control and that alternative options should be considered in the grasslands of Inner Mongolia.
