Abstract

Snow peas intercropped with faba beans in the Guatemalan highlands did not show a reduction in thrips densities compared to snow peas in monoculture, and faba bean does not appear to function as a trap crop. Thrips species composition differed markedly on each host, which may largely explain the results. Thrips tabaci was predominant on snow peas, while Frankliniella occidentalis was the main species on faba beans.

 

El cultivo de arveja china en asocio con haba en el altiplano de Guatemala no produjo reducción significativa de trips comparado con arveja china en monocultivo. No hubo evidencia que el haba funcione como cultivo trampa. La composición de especies de trips mostró diferencias marcadas entre hospederos, lo cual ayuda a explicar los resultados. La especie predominante en arveja china fue Thrips tabaci mientras que la especie principal en haba fue Frankliniella occidentalis.
