Ecologically-based preventative management of grasshoppers has received limited attention due to the historical emphasis on grasshopper outbreak suppression and intervention. Mahowald AP, 1972. Schistocerca nitens : Observed on Painted Rock Mountain, Maricopa Co., Arizona, 01 Nov 2008. Schistocerca nitens. In the ‘Region de Los Llanos’ (plains region) of Durango, Mexico, where S. nitens is found, annual mean rainfall is 457 mm and the annual mean temperature 17 °C. When several references are cited, they may give conflicting information on the status. A contribution to insect embryology, 8:1-160. The flight patterns of adult S.nitens are more precise and faster than the gregarious S. piceifrons (Cano-Santana et al., 2006).

Johannsen OA; Butt FH, 1941. The Nitens Group of the genus Schistocerca is a diverse and problematic one due to the variability present both within species and across them.

In the area of greatest infestation on Oahu, for example, northeasterly trade winds frequently reach velocities of 40 km/h (25 mph). Zacatecas, Mexico: Universidad Autonoma de Zacatecas. The male copulatory organ is symmetrical and is a distinctive character for species identification (Song, 2002). Biology and ecology of Schistocerca nitens [ed. Biological control of insect pests by insect parasitoids and predators has also been proposed by Greathead and Greathead (1992). S. nitens is solitary (not gregarious) and non-migratory (sedentary), but under certain conditions can form swarms or outbreaks and cause damage to crops and native plant species. At present, S.nitens impact has not been estimated in areas where it causes problems. The external morphogenesis of grasshopper embryos, 43:161-169.
