description | The mite Tetranychus urticae is a key pest in papaya crop in Valle del Cauca (Colombia), and it has been generally controlled with chemical products; other management alternatives have not been used. Therefore, this study aimed to evaluate the effects of alternatives: plant extract (garlic-chili vegetable extract, Alisin®), mineral oil (vegetable fatty acid complex, Adimel®), entomopathogenic fungus (Successor®), chemical control (spiromesifen, abamectin, fenazaquin), untreated (control treatment) and farmer’s practices (14 applications of pesticides) in a randomized complete block design with three replications/treatment in a Hybrid Tainung-1 papaya crop in the municipality of Roldanillo. The sampling was done every 8 days by measuring the variables: number of leaves/plant, number of infested leaves/plant, number of floral structures/plant, number of fruits/plant, diameter of stem/plant (every 30 days), population of T. urticae/leaf and yield. It was found that the populations of T. urticae/leaf were low in entomopathogenic fungus (11.978) and chemical control (10.548), with no significant differences (P>0.05) from farmer’s practices (3.339). In contrast, the mite populations were very high in plant extract (22.086), mineral oil (20.411) and untreated (35.746), as compared to farmer’s practices. There was a significant difference in all treatments for the variable infestation from farmer’s practices, and the number of leaves/plant in mineral oil and untreated treatment was significantly different from farmer’s practices. No significant differences were found between the treatments in the rest of the evaluated variables. The entomopathogenic fungus turned out to be the best alternative for a management program of T. urticae in papaya in this region. |

El ácaro Tetranychus urticae es considerada una plaga clave del cultivo de papaya en el Valle del Cauca (Colombia) y su control ha sido generalmente con productos químicos sin probar otras alternativas de manejo. Por lo anterior, el objetivo de este estudio fue evaluar en un cultivo de papaya Hibrido Tainung-1, en el municipio de Roldanillo, el efecto de las alternativas: extracto de planta (extracto vegetal de ajo-chile, Alisin®), aceite mineral (complejo de ácidos grasos vegetales, Adimel®), hongo entomopatógeno (Successor®), control químico (spiromesifen, abamectina, fenazaquin), sin manejo (tratamiento control) y prácticas del agricultor (14 aplicaciones de plaguicidas), utilizando un diseño de bloques al azar con tres repeticiones/tratamiento. Se hicieron muestreos cada 8 días midiendo las variables número de hojas/planta, número de hojas infestadas/planta, número de estructuras florales/planta, número de frutos/planta, diámetro del tallo/planta (cada 30 días), población de T. urticae/hoja y rendimiento. Se encontró que las poblaciones de T. urticae/hoja fueron bajas en los tratamientos hongo entomopatógeno (11,978) y control químico (10,548), donde no presentaron diferencias significativas (P>0,05) con respecto a las prácticas del agricultor (3,339); en contraste, las poblaciones del ácaro fueron muy elevadas en los tratamientos extracto de planta (22,086), aceite mineral (20,411) y sin manejo (35,746) frente a las prácticas del agricultor. Se presentó una diferencia significativa en todos los tratamientos y prácticas del agricultor para la variable infestación y entre los tratamientos aceite mineral y sin control vs. prácticas del agricultor para número de hojas/planta. Del resto de variables evaluadas no se encontró diferencias significativas entre tratamientos. El hongo entomopatógeno resultó ser la mejor alternativa para un programa de manejo de T. urticae en papaya en el departamento.
