Abstract
La presente investigación se realizó con el objetivo de evaluar el uso de hembras vírgenes para la captura de machos de Elamospalpus lignosellus (Zeller) en caña de azúcar. Para obtener las hembras vírgenes se crio en condiciones de laboratorio E. lignosellus, una vez obtenidas las hembras. Los tratamientos consistieron en colocar 2, 4, y 6 trampas por hectárea (Anexo 7) más un tratamiento testigo sin colocación de la hembra. Para la distribución de las trampas se empleó un diseño de bloques completos al azar, con cuatro tratamientos y tres repeticiones. Los parámetros evaluados fueron: número promedio de machos capturados por trampa por tratamiento y número de brotes picados o barrenados por metro lineal. Los promedios obtenidos de machos capturados de E. lignosellus por tratamiento fueron 668 (T3) ,413 (T2) y 237 (T1), sin embargo, el análisis estadístico no mostro diferencia estadística significativa entre ellos, pero si con respecto al tratamiento testigo. La utilización de hembras vírgenes resulto eficaz para la captura de machos de E. lignosellus y redujo el número de tallos picados o barrenados en todos los tratamientos en un porcentaje que fluctuó entre 68 a 87 %.
ABSTRACT The present investigation was carried out with the objective of evaluating the use of virgin females to capture males of Elamospalpus lignosellus (Zeller) in sugarcane. In order to obtain the virgin females, they were bred in laboratory conditions E. lignosellus, once the females were obtained. The treatments consisted of placing 2, 4, and 6 traps per hectare (Annex 7) plus a control treatment without placing the female. For the distribution of the traps, a randomized complete block design was used, with four treatments and three repetitions. The parameters evaluated were: average number of males captured per trap per treatment and number of shoots chopped or bored per linear meter. The averages obtained from males captured of E. lignosellus by treatment were 668 (T3), 413 (T2) and 237 (T1), however, the statistical analysis showed no significant statistical difference between them, but with respect to the control treatment. The use of virgin females was effective for the capture of males of E. lignosellus and reduced the number of stems chopped or bored in all treatments in a percentage that fluctuated between 68 to 87%.
