Grasshopper problems in Yacutia (Eastern Siberia, Russia) Grasslands
Journal of Orthoptera Research 4, 29-34
Abstract: The zone of natural Yacutia grasslands is situated between 60-64°N and 130-135°E. Vegetation of the meadow-steppe occupies vast glades dispersed in woodlands. These glades are inhabited by a dozen grasshopper species, three of which (Chorthippus albomarginatus, Aeropus sibiricus, and Omocestus haemorrhoidalis) are of economic importance. Most (up to 98%) of the grasshopper population consists of C. albomarginatus, which can produce mass outbreaks in years with deficient rainfall. Overgrazed pasture grasslands are particularly subject to grasshopper depredation. A recent outbreak took place in 1986-87, and an upsurge was observed in 1992. Prospective control strategies are under discussion-including rotational grazing, grassland management, and effective utilization of appropriate chemical measures on limited areas based on phenology forecasts. Special consideration is given to the search for and possible utilization of alternative control agents.
