| 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. | ||
