FIELD EVALUATION OF SOME COMPOUNDS AGENT FOR CONTROLLING OLIVE FRUIT FLY DACUS OLEAE (GMELIN) (Diptera; Tephritidae) IN ALARISH, NORTH SENAI, EGYPT

In the present study two experimental trials were carried out to evaluate the efficacy of the food attractant (Buminal 800 ml / 20 L) mixture with Match EC 5% (IGR; 160 ml / 20 L) for controlling the olive fruit fly, Dacus oleae (Gmelin) on olive orchard at Alarish district, North Senai, Egypt during period from June to July 2006 and2007 by food attractant traps and partial spray for trees trunk. In 1st experimental trial, results showed that the mean of reductions percentages by using Handerson and Telton (1955) formula for both periods 2006 and 2007 were 39.02 % & 50.00% & 55.81 % & 75.0 % & 80.77 % and 41.03% & 53.33% & & 70.20% & 78.70% & 82.35%, respectively, % mean of reductions during the same periods 2006 and 2007 were 60.2 % and 65.1 %, respectively. Regarding the second experiment, data showed that the total number of % reduction for both year 2006 and 2007 were 29.27 % & 45.65 % & 55.81 % & 70.83 % & 78.0 % and 33.33 % & 48.81 % & 63.83 % & 74.47% & 76.47%, respectively. The mean percentage of reduction for all these samples were 56.06 % in 2006 and 59.4 % in 2007. The statically analysis (L.S.D0.05) showed that a positive highly significant correlation for traps attracting which values was 8.427** and 7.956** for both years 2006 and 2007, respectively.
