African armyworm "S. exempta" larvae feed almost exclusively on Poaceae, also called Gramineae. Poaceae is a family of flowering grasses which includes cereal grasses and the grasses of grasslands and pastures. The species targets most cereal crops, including maize, sorghum, rice, millet, and other grasses. Young caterpillars are also known to feed on wheat and oat seedlings. The larvae eat the upper and lower surfaces of the plant tissue first, preferring to feed on younger and recently germinated crops. Studies have shown that two larvae can completely consume a 10-day-old maize plant with 6-7 leaves, indicating the devastating potential of a high-density
Nonpathogenic organisms many different types or strains. One strain of a bacterium species can be nonpathogenic and another strain of the same bacterium can be pathogenic. Nonpathogenic organisms Nonpathogenic organisms are those that do not cause disease, harm or death to another organism and is usually used to describe bacteria. It describes a property of a bacterium - its ability to cause disease. Most bacteria are nonpathogenic. It can describe the presence of non-disease causing bacteria that normally reside on the surface of vertebrates and invertebrates as commensals. Some nonpathogenic microorganisms are commensals on and inside the body of animals and are
