Conventional maize vs. organic-polyculture maize agroecosystems: low abundance of Dalbulus maidis (Hemiptera: Cicadellidae) and high plant richness within the organic system
Abstract
The corn leafhopper Dalbulus maidis (DeLong), one of the most important pests of maize throughout Latin America, was found in greater numbers within conventional maize that received agrochemicals compared to the adults found within the organic-polyculture maize crop. This pattern is reported for first time in the present study in an organic polyculture of maize.
Sumario
La chicharrita del maíz, Dalbulus maidis (DeLong), una de las plagas más importantes del maíz en América Latina, se encontró en gran abundancia dentro de maíz cultivado en forma convencional que recibieron agroquímicos comparado a los adultos encontrados dentro de un policultivo orgánico de maíz. Este patrón es reportado por primera vez en este estudio en un policultivo orgánico de maíz.
