Abstract

REIS, Paulo R.; SOUZA, Júlio C. de; SOUSA, Elber de O.  and  TEODORO, Adenir V.. Spatial distribution of Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) in coffee plants (Coffea arabica L.). An. Soc. Entomol. Bras. [online]. 2000, vol.29, n.1, pp. 177-183. ISSN 1981-5328.  http://dx.doi.org/10.1590/S0301-80592000000100022.

The spatial distribution of the false spider mite Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae), vector of the ringspot virus, was studied in coffee plants (Coffea arabica L.), in order to assess the mite preferred sites. Samples were taken throughout leaves, branches and berries, from lower, medium and superior parts of the plants. The inner and the outer side of the plants were compared. All development stages of the mites were recorded. B. phoenicis was mostly found on the internal leaves, branches and berries, in the lower and medium parts of the plants. On the leaves, mites were localized mostly at the lower leaf surface, mainly next to the midrib. On the berries, eggs and mites were found mainly at the crown and peduncle. On the branches, they were found in the nodes and coat gap.

Keywords : Acari; false spider mite; ringspot virus; citrus.
