Aceria guerreronis

Definition

A minute eriophyid mite (family Eriophyidae) that infests developing coconuts, feeding beneath the perianth of immature nuts and causing scarring, deformation, and severe yield losses in coconut plantations worldwide. This species exemplifies the economic impact of acarines in tropical agriculture.

Etymology

Specific epithet honors Mexican acarologist Luis F. Guerrero; genus Aceria from Greek 'aceros' (pointed, sharp), referring to the pointed empodium characteristic of eriophyid mites.

Example

Aceria guerreronis populations can reduce coconut yields by up to 60% in heavily infested plantations; control relies on acaricide applications or biological control using predatory mites such as Neoseiulus baraki.

Usage Notes

Often cited as a model case of invasive acarine pest spread; first described from Mexico in 1965, now pantropical. The feeding site beneath the perianth (the cap-like structure covering the young nut) is diagnostic and influences control timing. Not to be confused with Raoiella indica (red palm mite), another invasive palm pest with different feeding habits and damage symptoms.
