Robert Nelson (entomologist)
Robert Hale Nelson (1903–1996) was an American entomologist, federal agriculture- and insecticide researcher, and leader within the Entomological Society of America. Nelson was born June 13, 1903 on a farm in Bristow, Nebraska. He received a B.S. in 1929 and a M.S. the following year from the University of Nebraska. Upon finishing his M.S. Nelson, in 1931 Nelson was hired by the USDA's Bureau of Entomology and Plant Quarantine. His entire career was spent at various positions in the USDA, in 1946 being put in charge of insecticide and acaricide screening. Moved in 1953 to USDA's Agricultural Research Service division, specifically ARS's Entomological Research Branch. During this time Nelson also took further graduate level courses at Iowa State College and Ohio State University. Starting in 1947 he simultaneously served on the Chemical Specialties Manufacturers Association's Insecticide Scientific Committee. Nelson held various positions within the ESA, most notably as E ...

Agricultural Research
Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists. History In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulphate) as a fertilizer.John Armstrong, Jesse Buel. ''A Treatise on Agriculture, The Present Condition of the Art Abroad and at Home, and the Theory and Practice of Husbandry. To which is Added, a Dissertation on the Kitchen and Garden.'' 1840. p. 45. In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entomological Research Branch
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many ...

University Of Nebraska Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school.

Chemical Specialties Manufacturers Association
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...
