caption_attribution_description: English: Coconuts injured by Eriophyes or Aceria guerreronis, the eriophyid coconut mite.
context_page_description: The eriophyid coconut mite, Aceria guerreronis, is a mite which infests coconut plantations. It is economically devastating, and can destroy up to 60% of coconut production. The immature nuts are infested and injured by mites feeding in the portion covered by the perianth of the immature nut.
context_section_description: Aceria guerreronis is the only member of its family considered to be a serious pest of coconuts. Coconuts take about twelve months to mature. Damage from the initial infestation under the perianth becomes apparent as the fruit develops and more of its surface becomes visible. The nut develops corky brown, fissured patches of damaged tissue and becomes distorted if the damage is on one side of the fruit and not the other. Further attacks on the same nut can occur but the number of mites present decreases as the nut nears full size, and by the time the nut is harvested, it is usually devoid of mites. Estimates of the amount of economic damage done by the mite range up to 60%.
