Abstract
El gorgojo común (Acanthoscelides obtectus Say) es una plaga agresiva en la pos cosecha de habichuelas (Phaseolus vulgaris L). Esta plaga ataca la semilla almacenada, lo que reduce la germinación y la calidad comercial de los granos. El uso de insecticidas es la práctica principal para controlar el gorgojo. El desarrollo de líneas de habichuelas con resistencia a los gorgojos puede reducir el daño causado por esta plaga y disminuir el uso de plaguicidas durante el periodo de almacenaje del grano. Los investigadores del Centro Internacional de Agricultura Tropical (CIAT) han identificado líneas de habichuelas con resistencia a los gorgojos en la habichuela y el frijol tépari (P. acutifolius L.) En los últimos años, los fitomejoradores en la Universidad del Estado de Oregon (UEO) han desarrollado poblaciones interespecíficas que presentan un mayor nivel de resistencia a esta invasiva plaga. En Puerto Rico no hay información sobre la reacción de las líneas de habichuela de UEO cuando son expuestas a los gorgojos presentes en la Isla. A. obtectus Say fue identificado como la especie de gorgojo de la habichuela en la Subestación Experimental de Isabela. Una técnica de evaluación sencilla fue efectiva en la identificación de líneas de frijol con resistencia a los gorgojos. Cultivares de habichuela de Puerto Rico, República Dominicana, Haití, Honduras, Ecuador y Angola fueron susceptibles a esta especie de gorgojo. La línea, PR1012-29-3, derivada del cruzamiento„Rojo*3/SMARC2///ICAPijao*2/G40199‟, tenía el nivel más alto de resistencia a los gorgojos. Esta línea fue utilizada como progenitor en cruzamientos para combinar la resistencia a los gorgojos con la resistencia a las enfermedades virales Bean Golden Yellow Mosaic Virus (BGYMV), Bean Common Mosaic Necrosis Virus (BCMNV) y Bean Common Mosaic Virus (BCMV).
The common bean weevil (Acanthoscelides obtectus Say) is a serious post-harvest pest in common bean (Phaseolus vulgaris L). This pest attacks the stored seed, reducing germination and commercial quality of beans. The use of insecticide is the main practice employed to control bean weevils. The development of bean lines with resistance to weevils can reduce the damage caused by this pest and reduce the use of pesticides during the storage of grain. CIAT (Centro Internacional de Agricultura Tropical) researchers have identified sources of resistance to weevils in common bean and tepary bean (P. acutifolius L.). In recent years, breeders at Oregon State University (UEO) have developed interspecific populations that provide a higher level of resistance to this important pest. In Puerto Rico, there is no information concerning the reaction of the UEO bean lines when infested with weevils present on this island. Acanthoscelides obtectus Say was identified as the species of weevils present at the Isabela Substation. A simple evaluation technique was effective in identifying lines with resistance to bean weevils. Bean cultivars from Puerto Rico, Dominican Republic, Haiti, Honduras, Ecuador and Angola were susceptible to the common bean weevil. The line, PR1012-29-3, derived from the cross 'Red *3/SMARC2 / / / ICAPijao *2/G40199' had the highest level of resistance to weevils. This line was used as parent in crosses to combine resistance to weevils with resistance to the viral diseases Bean Golden Yellow Mosaic Virus (BGYMV), Bean Common Mosaic Necrosis Virus (BCMNV) y Bean Common Mosaic Virus (BCMV).
