Kiwifruits, notwithstanding their late arrival in Chile, were immediately subject to mite colonization, thus posing another quarantine problem to some importing countries, namely the USA. Growth Stages Top of page Fruiting stage, Vegetative growing stage.

However, they are subject to post-harvest mandatory fumigation treatments to importing markets such as Mexico and the USA. Red wine cultivars suffer the most due to false mite feeding through the spring and summer. Table grape cultivars, with the exception of a couple of old red varieties, are practically not attacked by the mite and bunches can be harvested without mobile stages on the berries. No twisting or distortion occurs. The distribution in this summary table is based on all the information available.

Chillensis fruit trees, the vines are the most economically affected crops, particularly red grape wine cultivars, which must be treated with chemical acaricides to deplete populations.

When several references are cited, they may give conflicting information on the status.

Brevipalpus is a large, widespread genus, including over 65 species of very small flat mites. The forthcoming invasion of the leaves in early summer may produce leaf rolling and discoloration of the leaves; grape bunches are also damaged by feeding. They can be easily found in preferred host plants with the aid of a x15 magnification hand lens. The latter species is recognized as a major mite predator, particularly against tetranychid mites.

Shortly after, the false mite was found to occur throughout the major wine grape areas in central Chile.
