| dc.description | At a global level, the potato has great economic and social importance as it is the fourth most consumed crop in the world, after corn, wheat and rice. The objective of the research was to detail the importance of the leafminer fly (Liriomyza spp) in the cultivation of Potato (Solanum tuberosum), in Ecuador. The conclusions determine that according to producers, potato production can be reduced by up to 40%. Furthermore, the increase in costs that its control entails makes it important; Since 2013, the Ecuadorian province of Carchi has seen signs of mumps, including leaf curling, purple or yellowing of leaves, development of aerial tubercles, and early senescence; The larvae mainly damage the leaves by creating mines or galleries by boring between the upper and lower surfaces of the leaves, destroying the mesophyll. As the larvae develop, the size of the mines increases and causes more foliar damage. At first the tunnels are small; By counting the feeding points on a sample of leaflets or making an educated guess about the surface that has been impacted, the adult insect is tracked. The number of leaflets that contain mines for the larvae is measured. The adult population is evaluated using yellow traps; Chemical control is carried out: Larvae control: Trigard (Cyromazine) 50 G/200 L. Vertimec (Abamectin) 100 cm3 /200 L. Basudin (Diazinon) 250cm3 /200 L. Adult control: Ninja (Lambda Cyhalothrin) 100 cm3 /200 L. Bronka (Alfacypermethrin) 250 cm3 /200 L. Cypermethrin 25 (Cypermethrin) 100 cm3 /200 L.; since they may contain Liriomyza spp. At various stages of development, broadleaf weeds and senescent crops are destroyed and buried as part of cultural control, and three different types of parasitoid larvae have been found in Ecuador: Closterocerus sp. and Chrysocharis sp. together with Neochrysocharis sp. | es_ES |

| dc.description.abstract | A nivel mundial, la papa tiene gran importancia económica y social por ser el cuarto cultivo más consumido en el mundo, luego del maíz, trigo y arroz, el objetivo planteado en la investigación fue detallar la importancia de la Mosca minadora (Liriomyza spp) en el cultivo de Papa (Solanum tuberosum), en Ecuador. Las conclusiones determinan que según los productores, la producción de patatas puede reducirse hasta en un 40%. Además, el incremento de costes que supone su control lo hace importante; desde 2013, la provincia ecuatoriana de Carchi ha visto signos de paperas, incluido el enrollamiento de las hojas, coloración púrpura o amarillenta de las hojas, desarrollo de tubérculos aéreos y senescencia temprana; las larvas dañan principalmente las hojas creando minas o galerías al perforar entre las superficies superior e inferior de las hojas, destruyendo el mesófilo. A medida que las larvas se desarrollan, el tamaño de las minas aumenta y causan más daño foliar. Al principio los túneles son pequeños; contando los puntos de alimentación en una muestra de folíolos o haciendo una suposición fundamentada sobre la superficie que ha sido impactada, se lleva a cabo el seguimiento del insecto adulto. Se mide la cantidad de folíolos que contienen minas para las larvas. Mediante trampas amarillas se evalúa la población adulta; el control químico se realiza: Control de larvas: Trigard (Ciromazina) 50 G/200 L. Vertimec (Abamectina) 100 cm3 /200 L. Basudin (Diazinon) 250cm3 /200 L. Control de Adultos: Ninja (Lambda Cihalotrina) 100 cm3 /200 L. Bronka (Alfacipermetrina) 250 cm3 /200 L Cipermetrina 25 (Cipermetrina) 100 cm3 /200 L.; dado que pueden contener Liriomyza spp. en diversas etapas de desarrollo, las malezas de hoja ancha y los cultivos senescentes se destruyen y entierran como parte del control cultural y en el Ecuador se han encontrado tres tipos diferentes de larvas de parasitoides: Closterocerus sp. y Chrysocharis sp. junto con Neochrysocharis sp. | es_ES |
