Curtis Paul Clausen
Curtis Paul Clausen (March 28, 1893 – February 28, 1976) was an American entomologist and professor at the University of California, Riverside, who specialized in biological control. He wrote an influential text on the biology of insect predators and parasites, ''Entomophagous Insects'' (1940). Clausen was born in Randall, Iowa in a family of Danish immigrants, and grew up on the family farm in Oklahoma and from 1910 in Ontario, California. He graduated from the University of Berkeley in 1914 and received an MS in entomology in 1920. He then worked at the citrus experiment station for two years under H.J. Quayle before assisting H.S. Smith at the State Insectary in Sacramento. From 1916 to 1918 he traveled across Asia seeking natural enemies of citrus scale insects. He served in the US Army Coast Artillery for fourteen months and joined the US Department of Agriculture at the Bureau of Entomology in 1920. He then traveled around the world searching and studying the biology of po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
