| dc.description.abstract | Liriomyza huidobrensis B. es una plaga económicamente importante en cultivos de vegetales y ornamentales, que ha desarrollado resistencia por el indiscriminado uso de pesticidas para su control, sin embargo, investigaciones han mostrado que existen diversos parasitoides y predadores que contribuyen a reducir su población. El objetivo de esta investigación se enfoca en buscar estrategias de liberación de enemigos naturales. A través de un diseño completamente al azar se implementaron cajas entomológicas de tela tul, dentro de las cuales se ubicaron cilindros PVC cubiertos de mallas con diferentes tamaños de orificio (1, 0.96 y 0.65 mm2). Los insectos se colectaron con una máquina aspiradora del cultivo de Gypsophila paniculata L, los cuales se colocaron en los cilindros PVC de cada caja, luego de 48 horas se contabilizaron el número de individuos de Diglyphus isaea W., Coenosia attenuata S. y Liriomyza huidobrensis B. en cada cámara. Los resultados mostraron que existe 96% de minadores, 3% de D. isaea, y menos del 1% de C. attenuata, mostrando diferencia en la liberación de parasitoides en los distintos tipos de mallas. En la malla de 1 y 0.96 mm2, se liberó el 90%, mientras que en la malla de 0.65 mm2, el 94% del total de D. isaea; a diferencia de Liriomyza que permaneció en el cilindro PVC entre el 58 y 75%. Esta investigación sugiere que la estrategia del uso de la aspiradora para control de minador es una herramienta eficiente para el manejo de control biológico, sin embargo, se debe considerar las mallas adecuadas y el tiempo indicado para la liberación de enemigos naturales. | es_EC |

| dc.description.abstract-en | Liriomyza huidobrensis B. is an economically important pest in vegetable and ornamental crops, which has developed resistance due to the indiscriminate use of pesticides for its control. However, research has shown that various parasitoids and predators contribute to reducing the population of this species. The objective of this research focuses on searching for strategies to release natural enemies. Using a completely randomized design, entomological boxes were located with PVC cylinders covered with meshes of varying hole sizes (1, 0.96, and 0.65 mm²). Insect populations were collected using a vacuum machine from a crop of Gypsophila paniculata L. Insect sample were placed in PVC cylinders within each box. After 48 hours, the number of individuals of Diglyphus isaea, Coenosia attenuata, and Liriomyza huidobrensis was counted in each chamber. The results showed that 96% of the leafminers, 3% of D. isaea, and less than 1% of C. attenuata exhibited a difference in the release of parasitoids through various types of mesh. In the study, 90% of the D. isaea population was released using the 1 mm² and 0.96 mm² mesh, while 94% was released with the 0.65 mm² mesh. In contrast, between 58% and 75% of Liriomyza remained trapped in the PVC cylinder. This research suggests that using a vacuum machine to control leaf miners can be an effective strategy for biological control. However, it is important to consider the appropriate mesh sizes and the optimal timing for the release of natural enemies. | es_EC |
