RODRIGUEZ, H; RAMOS, Mayra  y  SURIS, Moraima. PREDATORY MITES: AN ALTERNATIVE FOR THE CONTROL OF Thrips palmi KARNY (THYSANOPTERA: THRIPIDAE). Rev. Protección Veg. [online]. 2007, vol.22, n.2, pp. 89-96. ISSN 2224-4697.

In order to determine the importance of predatory mites in the regulation of Thrips palmi populations, 95 samplings were carried out in 23 different crops from May 1997 to December 2000 in La Habana and Ciudad de La Habana provinces. Twenty five leaves or 10 flowers damaged with thrips were taken. Species richness of the predatory mites was determined. Two crops of Solanum tuberosum, localized in San José de las Lajas and Güira de Melena municipalities were compared through ecological indexes. Other qualitative and quantitative observations were carried out in field and laboratory. Twenty four predatory mite species belonging to Phytoseiidae, Blattisociidae, Ascidae and Laelaptidae family were identified. The Phytoseiidae family was the most representative with 20 species, generally with generalist food habit. San José de las Lajas potato crops presented the highest species richness and diversity. The implications of these results for T. palmi management are discussed.
