| Aceria guerreronis Keifer can cause severe damage to coconuts in several countries around the world. Rare studies have been conducted to determine the predatory mites associated with A. guerreronis in Brazil. The study evaluated the prevalence of A. guerreronis and associated predators on the bracts and on the surface of the fruits underneath the bracts, for 12 months, on coconut palms grown along the coast of the States of Alagoas, Paraíba and Pernambuco, Northeastern Brazil. Mites of 10 families were found, but by far the most abundant species was A. guerreronis, corresponding to 99.5% of the mites collected. The prevailing species amongst the predators were the Phytoseiidae mites Neoseiulus baraki (Athias-Henriot) and Neoseiulus paspalivorus (De Leon).... |

| Abstract The coconut mite, Aceria guerreronis Keifer (Acari: Eriophyidae), is one of the main pests of the coconut crop by attacking the fruits. Colonies can reach 10,000 mites/fruit at high infestation. A diagrammatic scale (Galvão scale) has been developed and tested by Brazilian researchers to estimate the number of mites/fruit by determining the percentage of necrotic area of the fruit surface. Our objective was to develop and validate a new diagrammatic scale based on the percentage of the damaged perimeter of the fruit at the base of the perianth, in order to facilitate and improve the quantification of A. guerreronis per fruit. Fruits were collected in an urban coconut plantation in Ilhéus, Bahia, Brazil. For the development of the new diagrammatic... |
