Propuesta de muestreo para Neohydatothrips signifer (Thysanoptera: Thripidae) en el cultivo de maracuyá

Abstract: Resumen -El objetivo de este trabajo fue desarrollar una propuesta de muestreo de Neohydatothrips signifer en el cultivo de maracuyá. Se correlacionó la infestación promedio del trips en el cultivo con las variables meteorológicas de humedad relativa, temperatura y precipitación, con uso del coeficiente de correlación de Pearson. Así mismo, se determinó el índice de agregación de la población en el cultivo, con la prueba chi cuadrado (X 2 ) para la distribución de Poisson, la prueba de la razón V²/μ, y la dist… Show more

“…Therefore, 15 sampling events in the plant adjacent to every sticky trap were carried out. The sampling of every plant was performed by beating three times one branch against a white letter paper (22x28 cm) as described by Santos et al (2012a). Three sub-samples (i.e.…”

“…Previous studies have proposed a monitoring protocol (Santos et al, 2012a) which provides an economic threshold for N. signifier in yellow passion crops of 6-10 thrips per terminal bud depending on the mean temperature (Santos et al, 2012b). However, no study to date has attempted to establish the effectivity of sticky traps equipped with semiochemicals to control this pest species.…”
