تعیین میزان رهاسازی مناسب فرومون سوسک شاخدار خرما برای استفاده در تله های فرومونی

Date palm fruit stalk borer, Oryctes elegans Prell. (Col.: Scarabaeidae) is one of the most important pests of palm in Iran and Asia. 4- methyloctanoic acid has been identified as the essensial component of the male aggregation pheromone of O.elegans. An experiment on the determination of the best dose of aggregation pheromone of O. elegans for using in pheromone traps, have been carried out in infested date palm groves of Saravan region during 2004-2005. The reasults showed that different release rates (1.3-9.2 mg/day ) of 4- methyloctanoic acid compound combined with date palm core were equally attractive.Also there was not a significant difference in the number of catches by traps baited with pheromone and date palm core in comparison with traps baited with two males beetles(+date palm core).In the filed, 1.3-9.2 mg/day release rates of 4- methyloctanoic acid were active.So higher dose were not evaluated because release rates 1.3-3.5 mg/day were as good as the higher dose of 9.2 mg /day and can be used in pheromone traps. Key words : Date palm fruit stalk borer, Attraction, Aggregation pheromone, Date palm core
