Abstract
The olive fruit fly, Bactrocera oleae Rossi is a serious pest attacking olive fruits causing a quantitive and qualitative damages. The response of olive fruit fly adults to some ammonium compounds and certain food attractants was evaluated under field conditions throughout two experimental trails. The study was carried out at olive orchards of Dakhlia governorate by using the modified Nadel traps during the period of July 2011 until January 2012. The obtained results illustrated that the olive fruit fly, B. oleae exhibited different responses to the tested compounds depending on the average temperature and used concentration. For the 1st trail, six local ammonium compounds including ammonium acetate, di-ammonium phosphate, ammonium chloride, ammonium carbonate, ammonium hydroxide and ammonium bicarbonate were evaluated as lures for B. oleae adult flies. Four concentrations (1,2,3 and 4%) of each compound were evaluated during months of July, September and October 2011.
Among all tested ammonium compounds, two concentrations of Ammonium acetate (3 & 4%) exhibited the highest efficiency and lured ,8.25 & 8.00 flies/ trap/14 days. In the second trial, certain food attractants were evaluated in comparison with diammonium phosphate and ammonium acetate ( at 1, 2, 3 and 4 %) during October, December 2011 and January 2012. The tested food attractants included Buminal, Prolure and Conserve (GF-120) at concentrations of 2.5, 5 and 10%. In addition Torula yeast was also evaluated at rates of 2, 3 and 4 pellets of Torula yeast /300 cm3 water. Diammonium phosphate 2, 3, 1% and Buminal 2.5% recorded the highest efficiency with 19.58, 18.58, 17.08 and 16.52 flies/trap/ 14 days, respectively. The obtained results indicate that di-ammonium phosphate and ammonium acetate could be involved in population monitoring and mass trapping technique of B. oleae as a part of its integrated control program due to their superiority in female attractancy of B. oleae and lower cost when compared with other food attractants.
