A contribuição teórico-metodológica da "Vª Jornadas Interdisciplinarias de Estudios Agrarios y Agroindustriales"

Abstract

O presente relato de experiência destaca a estrutura, bem como as contribuições teórico-metodológicas das "V Jornadas Interdisciplinarias de Estudios Agrarios y Agroindustriales", evento organizado a cada dois anos, que aconteceu de 7 a 9 de novembro de 2007 na Universidade de Buenos Aires (UBA), sob responsabilidade da Faculdade de Economia, onde estiveram presentes centenas de pesquisadores latino-americanos.

Population genetic diversity in Nezara viridula by analysis of mitochondrial control region sequences

“…This result is consistent with the expansion of soybean crops in Argentina, which began in the east of the province of Córdoba and south of Santa Fe. Subsequently, soybean crops continued to spread to other areas, including the centre and south of Córdoba and the north of La Pampa, where they present a lower density because they were recently established (Conte et al, 2007; Martínez‐Alvarez, 2012; Viglizzo & Jobbágy, 2010). The results of migrants per generation obtained in the Lamarc program suggest that the direction of migration of N. viridula would be associated with the growth pattern of the populations of its host plant.…”

“…The incorporation of technology, mainly in soybean crops, has produced a rapid increase in the cultivated area. In this regard, the area cultivated with soybeans increased from 1,700,000 to 13,000,000 hectares in the period 1970–2021 (Conte et al, 2007; Informe Soja, 2021–2022). The specimens analysed in this work were collected in localities of three provinces (Córdoba, Santa Fe and La Pampa) belonging to the region with the highest agricultural productivity in Argentina.…”

“…The specimens analysed in this work were collected in localities of three provinces (Córdoba, Santa Fe and La Pampa) belonging to the region with the highest agricultural productivity in Argentina. Córdoba and Santa Fe are among the provinces where there has been a significant growth in the area cultivated with soybean (Conte et al, 2007; Martínez‐Alvarez, 2012; Viglizzo & Jobbágy, 2010). Since soybean is the preferred host of N. viridula , the increase in the cultivated area of this host plant would improve fecundity and survival of the insect.…”
