Weight loss of copra due to infestation by Aceria guerreronis

2010
The commonly known coconut mite, Aceria guerreronis, inhabits the meristematic tissue of the coconut and has a high reproductive potential, hence it is important to assess its impact on coconut yield loss. This article focuses on yield loss in terms of copra. Infestation by A.

Distribution of Aceria guerreronis and Neoseiulus baraki among and within coconut bunches in northeast Brazil

Experimental and Applied Acarology, 2011
Aceria guerreronis Keifer (Acari: Eriophyidae) is considered a major pest of coconut in many countries in the Americas, Africa and parts of Asia. Neoseiulus baraki Athias-Henriot (Acari: Phytoseiidae) is one of the predatory mites most commonly found in association with A. guerreronis in parts of northeast Brazil.

Management of Coconut Eriophyid Mite (Aceria guerreronis K.) to Revive Coconut Cultivation in Bangladesh

2023
Coconut mite injures the tender portion of young nuts and suck sap. Initially the damage appears as a triangular yellowish brown patch extending distally on the fruit surface from beneath the perianth. The injury ultimately leads to warting and longitudinal fissures on the nut surface. The growth of nut is prevented and ultimately the usual size of the

Rearing of coconut mite Aceria guerreronis and the predatory mite Neoseiulus baraki in the laboratory

Experimental and Applied Acarology, 2007
A method was developed for the rearing of coconut mite, Aceria guerreronis Keifer (Acari: Eriophyidae), and its predatory mite Neoseiulus baraki (Athias-Henriot) (Acari: Phytoseiidae) on embryo culture seedlings of coconut (Cocos nucifera) in the laboratory. Seedlings in the ages of

Occurrence and seasonal prevalence of the coconut mite, Aceria guerreronis (Eriophyidae), and associated arthropods in Oman

Experimental and Applied Acarology, 2013
The coconut palm is an important crop in the sub arid coastal plain of Dhofar, Oman, for the high demand for its nut water and its use as ornamental plant. Damage of coconut fruits by the eriophyid mite Aceria guerreronis Keifer was first reported in that region in the late 1980s, but background information about the ecology of the pest in Oman was ...

Fusarium species: acaropathogenic fungi as potential control agents against coconut mite, Aceria guerreronis

2010
Aceria guerreronis (Acari: Eriophyoidea) inflicts severe damage on the nuts of commercial coconut palms. Investigations were carried out in India and Sri Lanka to investigate the association of mycopathogens with A. guerreronis. Mite-infested nuts were collected, brought to the laboratory, and examined for the presence of fungi associated with A ...

A New Method to Estimate the Population Size of Coconut Mite, Aceria Guerreronis, on a Coconut

Experimental and Applied Acarology, 2005
Studies of the coconut mite, Aceria guerreronis, often require accurate assessment of the population density on individual infested coconuts. Here an efficient and accurate method was developed to estimate its population density on an infested coconut. The coconut mites were removed by washing the bracts and surface of an infested coconut with 30 ml of

L'acariose à Aceria guerreronis (Keifer), ravageur du cocotier

1970
L'incidence des attaques de Aceria guerreronis sur la production est envisagée sous deux aspects : chute des noix immatures et réduction en coprah. Les pertes par chute des fruits sont difficiles à estimer avec précision mais n'excèdent pas quelques p. 100.

Status of coconut mite Aceria guerreronis and biological control research in Sri Lanka

2010
The coconut mite, Aceria guerreronis (Acari: Eriophyidae), invaded Sri Lanka in 1997, and subsequently spread in many areas infesting 17% of the total coconut extent by 2005. It is more prevalent in the dry zone than in the intermediate and wet zones. Within each year, populations fluctuated with high peaks in June-August and relatively low levels in ...
