Rufous grasshopper of "G. rufus" through the use of feces as a source of DNA. It has been documented to eat plants of the genus "Bromus", the species "Holcus lanatus", and the subfamily Pooideae, all within the family Poaceae. Poaceae is a family of flowering monocots whose members are referred to as true grasses. Pooideae includes lawn grasses and cereals such as wheat and barley. "Bromus" is composed of grasses called brome grasses or cheat grasses. "Holcus lanatus", more commonly known as Yorkshire fog or velvet grass, is a species of perennial pasture grass noted for its hairy texture. The rufous grasshopper
Detection of genetically modified organisms near infrared light, chemical bonds in the sample vibrate and re-release the light energy at a wavelength characteristic for a specific molecule or chemical bond. It is not yet known if the differences between GMOs and conventional plants are large enough to detect with NIR imaging. Although the technique would require advanced machinery and data processing tools, a non-chemical approach could have some advantages such as lower costs and enhanced speed and mobility. The Cantons of Switzerland perform tests to assess the presence of genetically modified organisms in foodstuffs. In 2008, 3% of the tested samples contained detectable amounts of
