Data on natural enemies in the regulation of S.nitens populations are scarce (Latchininsky, 2008). The NPARL (Northern Plains Agricultural Research Laboratory) is working to bring the existing isolates into the USA for large-scale field trials in cooperation with USDA APHIS and the University of South Utah (Diaz-Soltero, 2009; Foster et. > 10°C, Cold average temp. [ed. diet) and abiotic (e.g. (Acridoideos (Insecta: Orthoptera) del Estado de Guanajuato, Mexico)., 89 29-38. Duffy DC, 2010. Proceedings of the Hawaiian Entomological Society, 22(3):451-456, Branson DH, 2006. Acridoideos (Insecta: Orthoptera) of the State of Guanajuato, Mexico. Latchininsky (2008) is one of the references that reported the plant species affected in the 2002-2004 outbreak in Nihoa Island, Hawaii. Each pod contained an average of 66 ±20 eggs (32 minimum to 97 maximum). Stn. A Hawaii Biological Survey Handbook. First ecdysis occurs within 10 minutes when the cuticle of the first instar nymph splits along the mid-dorsum. Although grasshopper herbivory can have negative economic consequences, it may also have important ecological consequences of interest to land managers and conservation organizations such as effects on plant community structure and rangeland productivity. In S. nitens, this asynchrony was often less than ±0-5% of total developmental time. Nymphs are green or occasionally brown (Mariño-Perez et al., 2011). Preliminary study of some insects and mites, pests of cultivated cassava (M. esculenta) in Zulia State, Venezuela. RAAT's treatments. Females laid eggs 10-15 days during their life span. (1977) studied the dispersal and mechanical vectors of the diseaseand concluded that the possible role of insects as mechanical vectors remained speculative. USDA Agricultural Research Service Northern Plains Agricultural Research Laboratory. S. nitens (Thunberg) is a short-horned grasshopper classified in the Family Acrididae. Distribution Atlas for grasshoppers and Mormon crickets in Wyoming 1987-2012. In: Genus Schistocerca (Acridomorpha, Insecta). Its hind tibia shows one inner dorsal apical immovable spine at tip. Records of the Hawaii Biological Survey for 2004-2005. Blue pigment persists within the antennae (Roonwal, 1947). Young adults started mating in 8 to 12 days. Proceedings of the Royal Society B. Likewise, subspecies described by Dirsh as S. nitens virginica, S. nitens nitens and S. nitens columbina are considered species and not subspecies. Researchers are also testing promising pathogens for their potential as biocontrol agents for grasshoppers, as well as examining the insect’s dietary preferences during different life stages, which could ultimately lead to new cultural methods for curbing population growth (USDA-ARS NPARL, 2012a).

Brust M L, Keim D L, Jenkins T M, 2015. Entries are listed below in alphabetical order (A-to-Z). S. nitens is also known as S. vaga (Scudder) in the USA (Bianchi and Kajiwara, 1966). Life-history responses of Ageneotettix deorum (Scudder) (Orthoptera: Acrididae) to host plant availability and population density. USGS. Insects serve as mechanical vectors for infectious Ustilago species, mainly U. violaceae and probably U. succisae (Ingold, 1971), and S. nitens may be a potential vector.

There are no pictures available for this datasheet, is now present in all the main islands of the Hawaiian archipelago, Data on natural enemies in the regulation of, Sugarcane harvest could force displaced insects to invade new areas. This causes grasshopper populations to collapse, and without new nymphs emerging from desiccated eggs.

It is far more infectious in Orthoptera than the currently registered Beauveria. As of 2012, these are the only two publications that document the species occurring in the Eastern Hemisphere.

There are a total of 37 North American Grasshoppers & Crickets in the Insect Identification database. Honolulu, Hawaii, USA: Hawaii Wildlife Fund. The name "bird grasshopper" is applied to members of the genus Schistocerca, apparently because of their large size, approaching that of small birds.
