Study of barley yellow dwarf virus: dynamics of aphid-plant interaction

Abstract Physics continues to be an inexhaustible source of problems that have inspired the theoretical development mathematics, particularly in theory dynamical systems their origin physics 15th century, with beginning differential calculus by Newton and Leibniz; equations are appropriate tool for research different areas knowledge. Our objective is show example how we can use a problem framed forestry agricultural systems, ecology, epidemiology. This work one essential primary crops energy intake human diet, wheat; as it turns out, productivity this food affected several biotic stresses, including viral diseases associated vectors. Among infections barley yellow dwarf virus, which causes 11% 33% yield losses wheat fields; virus moves through landscape via aphid species (vectors). The main aphids prefer colonizing plants causing rapid growth infected substantially decreasing crop productivity; therefore, propose study dynamics aphid-plant interaction, impact preference determined, obtained result key parameter quantity quality consumed aphids.
