A review of the status of the coconut mite, Aceria guerreronis (Acari: Eriophyidae), a major tropical mite pest

The coconut mite (CM), Aceria guerreronis Keifer, has spread to most coconut production areas worldwide and it has been considered one of the most notorious and important pests of coconut fruits in many countries. Although CM has been reported to damage coconuts for over 40 years in the Americas and Africa it continues to cause considerable losses in countries of these continents, and in the last 15 years it has also reached countries from southeast Asia—India and Sri Lanka. Several other countries of southeast Asia are also major coconut producers and the impact by the mite in currently affected areas suggests that the dispersion of CM to these major producers could lead to very heavy losses. Great advances about our knowledge on CM and its control have been achieved, especially in the last decade, after its introduction into Asia. However, much remains to be known to allow the design of efficient strategies to it. This paper brings together information on CM invasive history, distribution, hosts, morphology, biology, dispersal, colonization process, population dynamics, symptoms and injury, estimated losses, sampling techniques, control strategies and new perspectives for its control.
