Spinosad, Lufenuron and Malathion were evaluated in controlling olive fruit fly, Bactrocera oleae (Gmelin) under field conditions by using partial bait spray and killing bags during fruiting seasons of 2008 and 2009. The obtained results showed that the percentages of B. oleae populations and fruit infestation were obviously low in treated plots with Lufenuron, Spinosad and Malathion, respectively in comparison with control plot which were relatively high. The mean reduction percentages in B. oleae population in treated plots with Lufenuron, Spinosad and Malathion were 86.2±8.2, 77.3±3.0 and 71.3±11.2% during 2008 season and 74.8±10.1, 71.9±9.4 and 70.2±7.2% during 2009 season, respectively. While, the mean reduction percentages in fruit infestation by B. oleae larvae in treated plots with Lufenuron, Spinosad and Malathion were 77.5±6.5 & 73.1±5.1, 76.9±5.2 & 71.5±5.1 and 70.8±6.8 & 64.9±6.2% during 2008 & 2009 seasons, respectively.
