A novel approach for the control of the red palm weevil Rhynchophorus ferrugineus (F) using Microsporidia

THE MICROSPORIDIAN VAIRIMORPHA (NOSEMA) EPHESTIAE (MATTES) – (PROTOZOA, MICROSPORIDIA) WAS TESTED AGAINST THE RED PALM WEEVIL (RPW),RHYNCHOPHORUS FERRUGINEUS (F). THE PATHOGEN WAS ISOLATED FROM THE MEDITERRANEAN FLOUR MOTH LARVAE, EPHESTIA KUEHNIELLA ZELL , AND PROPAGATED SUCCESSFULLY ON THE SAME HOST OR ON THE EGYPTIAN COTTON LEAFWORM. THE PATHOGEN CAUSED LETHAL EFFECT TO RPW LARVAE ADULTS WHEN APPLIED AT 25 -100?106 …
