Abstract
The compatibility of essential oils and antimoulting hexaflumuron with
Egyptian isolates of the entomopathogenic fungus Beauven'a bassiana ( Balsamo)
was examined against the red palm weevil Rhyncnophorus ferrugrneus (Olivier) under
laboratory, greenhouse and field conditions . Effectiveness of fungus with the
addition of essential mint oil at a concentration of 2.5 mlfl toward red palm weevil was
increased in the laboratory. The results indicated that the impact of the combination of
fungus and antimoulting hexaflumuron inSecticide was variable, ranging from
synergism to antagonism depending on the concentration of hexaflumuron and larval
instars. Significant larval mortality in palm trees injected with a combination of fungus
(10a sporeslmi), mint oil (1.0 mill) and antimoulting hexafiumuron (0.1%) was evident
in greenhouse. in the field, using the combination applied by injection was an
effective method for controlling R. fenugineus in naturally infested palm trees in two
weeks .The success of the treatments was 98.9 %, 95.1 %, and 86.2 % within two
weeks after injection in light? median and heavy infestations, respectively. The study
suggests that curative control of R. ferrugr'neus in infested palm trees is highly too
possible with a combination of fungus B. bassiana, essential mint oil and
antimoulting hexaflumuron.
