description The whitefly Aleurotrachelus socialis Bondar (Hemiptera: Aleyrodidae) is one of the most important pests in cassava (Manihot esculenta Crantz) crops in the Neotropics. In Colombia, this is the major pest to the crop in the departments of Cauca, Valle del Cauca and Tolima, causing yield losses in experimental fields of up to 79%. Since 1995, this species has colonized and increased its populations in new varieties and areas where it was a secondary pest before. To estimate the potential of A. socialis to develop populations in new cassava varieties, the biological parameters and the main vital statistics of this pest were evaluated under controlled conditions (25± 2º C, 70±5% HR, 12L:12D) on the varieties Chirosa (Mcol 2066), Ica Armenia (HMC1) and CMC 40. The results indicated that A. socialis females lived for a longer time (6,4 days) on the genotype CMC-40 and showed a higher reproductive potential (33.8 eggs per female). On the contrary, the lowest developmental time (32,72 days) was obtained on the genotype HMC1. The three genotypes showed high survival rates, being highest on HMC1 (89%). The greatest population increase (rm) was found on HMC1 (0,167 day-1) and CMC40 (0,079 day -1). The biological and population parameters obtained constitute a basic tool to elaborate control strategies for A. socialis.

La mosca blanca Aleurotrachelus socialis Bondar (Hemiptera: Aleyrodidae) es una de las plagas más importantes en el cultivo de yuca (Manihot esculenta Crantz) en el Neotrópico. En Colombia, es el principal limitante del cultivo en los departamentos del Cauca, Valle del Cauca y Tolima ocasionando pérdidas en rendimiento en campos experimentales hasta del 79%. En 1995 esta especie ha colonizado e incrementado sus poblaciones en nuevas variedades y áreas donde anterior- mente era una plaga secundaria. Con el objetivo de conocer el potencial de A. socialis para desarrollar poblaciones en nuevos materiales de yuca, se estimaron los parámetros biológicos y los principales estadísticos vitales de este insecto plaga, realizando bioensayos bajo condiciones controladas (25± 2º C, 70±5% HR, 12L:12D) sobre las variedades Chirosa (MCOL 2066), Ica Armenia (HMC1) y CMC 40. Los resultados mostraron que las hembras de A. socialis vivieron más tiempo (6,4 días) sobre el genotipo CMC-40 y presentaron un alto potencial reproductivo (33,8 huevos por hembra). Por el contrario el menor tiempo de desarrollo (32,72 días) se obtuvo en el genotipo HMC1. Los tres genotipos presentaron altas tasas de supervivencia, siendo mayor en HMC1 (89%). El mayor incremento de las poblaciones (r m ) se presentó en los genotipos HMC1 (0,167 día -1) y CMC40 (0,079 día -1). Los parámetros biológicos y poblacionales obtenidos constituyen una herramienta básica para elaborar estrategias de control de A. socialis. 2006 2014-10-02T08:33:42Z 2014-10-02T08:33:42Z Journal Article https://hdl.handle.net/10568/44392 es Open Access
