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. |
