Subject(s): Online resources: In: Alexandria Journal of Agricultural Research 2010.v.55(2)Summary: A field experiment was conducted to evaluate the integrated effect of baited aggregation pberomone traps and entomopathogenic fungus Beauveria bassiana or insecticide for controlling the red palm weevil (RPW),Rhyncophorus fer-rugineus Olivier (Coleoptera: Rbyncbopboridae) through 2008-2009. Result< indicated that the intensity of captured weevils were decreased as a result of using combination of baited pheromone traps and fungus or insecticide compared with using baited pheromone trap only. Statistical analysis revealed significant differences between the mean numbers of captured adults in treated areas with baited pberomone traps alone and combination of traps and fungos or insecticide wbereas the total mean numbers were 17.04,4.93 and 8.02 adultsl3traps, respectively. The total mean reduction of RPW population caused by mass trapping and fungus B. bassiana or insecticide were 61.40% and 40.16% , respectively. Considerable reduction of infested palm tree numbers was noticed in treated areas with combination compared with untreated areas. There were significant differences among different field trials and untreated areas on mean numbers of infested palms. They were lower (0.77 and 0.82 palms) wben used combination of baited pheromone traps plus fungus and baited pheromone traps plus insecticide, respectively and higher (2.03 and 2.15 palms) when used mass trapping or insecticide alone. However the untreated areas recorded highest infested palm trees whereas mean number was 3.73 palms.
