  • Sep 2019
Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) is an economically important, internally feeding pest of ornamental and fruit-producing palms in many subtropical regions. A related weevil, Rhynchophorus cruentatus (Fabricius) (Coleoptera: Dryophthoridae), is an internally feeding palm pest in the southeastern USA. Acoustic methods...

  • Nov 2017
Rhynchophorus ferrugineus (Olivier; Coleoptera: Dryophthoridae) is a pest of many crop and ornamental palm tree species in subtropical regions worldwide. Larvae tunnel and feed unseen in the trunks, ultimately causing irreparable harm and killing the palm. Beauveria bassiana (Balsamo-Crivelli; Hypocreales: Clavicipitaceae) Vuillemin is under evalua...

  • Mar 2015
Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) is an economically important pest of palm trees in the subtropics. Beauveria bassiana (Balsamo-Crivelli) Vuillemin (Hypocreales: Clavicipitaceae), has been shown to be pathogenic against R. ferrugineus in laboratory and field studies. However, because they remain inside the trunks unt...

  • Dec 2013
A solid state formulation of Beauveria bassiana (Balsamo) Vuillemin has been developed for biological control of the Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Olivier, 1790). Two kinds of bioassays (dry conidia and dipping) using 10 isolates from several coleopterans in Mediterranean environments, identified 2 RPW derived isolates (193 and...

Chitosan increases conidiation in fungal pathogens of invertebrates
Article

  • Aug 2010
Antifungal activity of chitosan on plant pathogenic fungi has been widely studied, but little is known about the effect of chitosan on fungal biocontrol agents. In this work, we characterize the increase of conidiation induced by chitosan in fungal pathogens of invertebrates (FPI). Chitosan increased conidiation of FPI, including Beauveria bassiana...

Infection of the Red Palm Weevil ( Rhynchophorus ferrugineus ) by the entomopathogenic fungus Beauveria bassiana : A SEM study
Article
  • Jan 2009
The Red Palm Weevil (Rhynchophorus ferrugineus) is a devastating pest of palms in the Mediterranean, Middle East, and Eastern countries. No effective control measures are available. R. ferrugineus has been found naturally infected by the entomopathogenic fungus Beauveria bassiana, but its infection process in this host is unknown. We have studied t...
