Importancia de los ácaros en los cítricos (Citrus spp)

Citrus crops, oranges, tangerines, limes, lemons and grapefruit, are some of the most cultivated fruits in the world. From a nutritional point of view, citrus fruits are characterized by being a source of vitamins (vitamin C, folic acid, vitamin A.), minerals (potassium, with a slight diuretic effect) and antioxidants. Currently citrus fruits are grown in most of the tropical and subtropical regions of the planet between the parallels 44° North 41° South, demonstrating the high capacity of adaptation to a wide climatic condition. This allows distribution in several regions with different climatic conditions, however, the environmental condition of the environment can significantly alter the characteristics of the plants such as height, appearance of the leaves, longevity of the fruits. For example: shape, size, shell color, pulp color, texture, acid and sugar content. The mite bites produce a diffuse and dull discoloration of the epidermis of the organs in which it lives, leaves, fruits and tender branches. The main damage occurs at the end of summer and in autumn, a time when it causes significant quality losses in the fruits by discoloring them and giving them a matte appearance. They comprise between 15 and 20% of the pest species with the greatest economic impact on crops. Many lines of mites have evolved from the supposed predation of the primitive arachnid, to practically adopting every form of resource exploitation imaginable.
