First report of the exotic species Megalurothrips usitatus (Thysanoptera: Thripidae), pest of Fabaceae, in Puerto Rico
Abstract
Megalurothrips usitatus (Bagnall) (Thysanoptera: Thripidae) has been recently found throughout the bean growing regions of Puerto Rico. Megalurothrips usitatus was observed affecting the Andean bean lines (Phaseolus vulgaris L.), Glycine max (L.), and Phaseolus acutifolius L. This is the first time M. usitatus has been reported from Puerto Rico. Given the high risk that this pest represents to legumes in Puerto Rico, it is necessary to evaluate which bean growing area and which local crops could be most affected.
Megalurothrips usitatus (Bagnall) (Thysanoptera: Thripidae) se ha encontrado recientemente en todas las regiones productoras de frijol de Puerto Rico. Se observó que Megalurothrips usitatus afecta a las líneas de frijol andino (Phaseolus vulgaris L.), a Glycine max (L.) y también a Phaseolus acutifolius L. Esta es la primera vez que se reporta M. usitatus en Puerto Rico. Dado el alto riesgo que representa esta plaga para las leguminosas en Puerto Rico, es necesario evaluar qué zona de cultivo de habichuela y qué otros cultivos locales podrían verse más afectados.
