Abstract

We describe the effect of a Beauveria bassiana solid formulation on Rhynchophorus ferrugineus infesting naturally canary palms in SE Spain in the field. The formulation included a highly pathogenic strain of B. bassiana derived from R. ferrugineus. The formulation was applied 3 times in 2009 in 2 sites (Catral and El Hondo), at 3-month intervals. Beauveria bassiana caused 70–85% R. ferrugineus mortality. Beauveria bassiana solid formulation with high RPW pathogenicity and persistence, could be applied as a preventive as well as curative treatment for RPW control. Our B. bassiana formulation can be a significant component of an IPM strategy for RPW control.

En este artículo se describe el efecto de un formulado sólido a base de Beauveria bassiana contra Rhynchophorus ferrugineus infestando de forma natural palmeras canarias en campo (SE España). El formulado incluye un aislado obtenido de R. ferrugineus altamente patogénico contra la plaga. El formulado se aplicó tres veces en dos localidades (Catral y El Hondo) en 2009, con un intervalo de tres meses entre las aplicaciones. Beauveria bassiana causó un 70-85% de mortalidad en R. ferrugineus. Este formulado seco con alta patogenicidad sobre R. ferruginues y elevada persistencia en campo, podría utilizarse como medida tanto preventiva como curativa para su control. Nuestro formulado sólido y seco a base de B. bassiana podría aplicarse en programas de manejo integrado de R. ferrugineus.
