dc.description.abstractThis study was made to determine the life cycle, the effectiveness of various insecticides, and the damage of Holopothrips tabebuia, a new invasive species, in the western region of Puerto Rico. Holopothrips tabebuia took 23.5 days to complete the egg, larvae 1-2, prepupa, pupa and adult on White Cedar, Tabebuia heterophylla, saplings. Imidacloprid and acephate insecticides were very effective in controlling larvae and adult stages of H. tabebuia on saplings of White and Yellow Cedar (T. aurea) and Calabash (Crescentia cujete), while neem and orchard oils were ineffective. The thrips was found attacking trees of White cedar in urban, rural and forest areas between Mayagüez, Maricao and Sabana Grande municipalities. In Maricao and Sabana Grande forests, H. tabebuia was found attacking Red Cedar, T. schumanniana. The White Cedar was more susceptible to attack than other species in the Family Bignonaceae.en_US
dc.description.abstractEste estudio se realizó con el propósito de determinar el ciclo de vida, la efectividad de varios insecticidas, y el estado de daño de Holopothrips tabebuia, una nueva especie invasora, en la zona oeste de Puerto Rico. Holopothrips tabebuia tomó 23.5 días en completar las etapas de huevo, larva1-2, prepupa, pupa y adulto en arbolitos de roble nativo, Tabebuia heterophylla. Los insecticidas imidacloprid y acephate fueron muy efectivos controlando larvas y adultos de H. tabebuia en arbolitos de T. heterophylla, roble amarillo (T. aurea) e higüero (Crescentia cujete), mientras que los aceites neem y de huerta no lo controlaron. El trípido se encontró atacando árboles de T. heterophylla en zonas urbanas, rurales y de bosque entre Mayagüez, Maricao y Sabana Grande. En los bosques de Maricao y Sabana Grande se encontró atacando el roble colorado, Tabebuia schumanniana. T. heterophylla es la especie de la familia Bignonaceae más susceptible al ataque de H. tabebuia.en_US
