          Abstract

          Los trips (Thysanoptera: Thripidae) son polífagos y, por lo tanto, son capturados en muchas especies de plantas cultivadas, lo cual no implica que en ellas se comporten como plagas. El objetivo de este trabajo fue relevar la presencia y abundancia trips, en los cultivos de especies ornamentales. En febrero de 2005 se colectaron flores de 65 especies de plantas, hallándose individuos adultos en diversos niveles de densidad en 49 de ellas. Las especies de trips más frecuentes y abundantes fueron: Thrips simplex (Morison) (trips del gladiolo), Frankliniella schultzei Trybom (trips de los capullos), Frankliniella occidentalis (Pergande) (trips californiano de las flores), Frankliniella insularis Franklin (trips del malvabiscus) y Frankliniella gemina Bagnall. Para T. simplex, plaga del gladiolo, se registró en sus flores una abundancia media (por flor) de 5 a 10 individuos (considerando adultos, juveniles o ambos). Niveles similares de densidad se registraron en otras plantas: F. schultzei en Lathyrus latifolius, Ipomea y Tropaleum majus, F. insularis en Punica granatum, Malvaviscus arboreus, Hibiscus rosa sinensis y Duranta erecta, y F. gemina en Agapanthus africanus y Dietes bicolor. Se espera que resultados preliminares puedan orientar futuras investigaciones sobre la interacción de especies de trips con estos cultivos.

          Translated abstract

          Since thrips (Thysanoptera: Thripidae) are polyphagous, they are usually caught in flowers of many crops, but it does not necessary mean they are pests. The aim of this survey was to list the thrips presence and abundance in ornamental crops. During february 2005 were collected flowers form 65 plant species, and they were recorded thrips, in different abundance levels in 49 plant species. The thrips species more frequently found were Thrips simplex (Morison) (gladiolus thrips), Frankliniella schultzei Trybom (blossom thrips), Frankliniella occidentalis (Pergande) (western flower thrips), Frankliniella insularis Franklin (malvaviscus thrips) and Frankliniella gemina Bagnall. For T. simplex - a gladiolus pest - it was recorded a mean abundance of 5 to 10 individuals per flower in that crop (considering larvae, adults or both). Similar densities were recorded also for F. schultzei in Lathyrus latifolius, Ipomea and Tropaleum majus, F. insularis in Punica granatum, Malvaviscus arboreus, Hibiscus rosa sinensis and Duranta erecta, and for F. gemina in Agapanthus africanus and Dietes bicolor. It is expected these preliminary results may assist in the establishment of priorities for future research on thrips-crops interaction.
