Abstract
The aim of this research is to study factors affecting thermal fogger for controlling “Parloria Blanchardi” on the date-palm trees. The outlet tube of the tested fogger was modified by addition tube of 1000 mm length with 30.8 mm diameter. So, the total resonator length increased to 1740 mm to suit with palm-tree heights and easy fog flow. The studied variables included fogger conditions (mobile fogger by human and fogger attached to tricycle), control materials (Malathion, Mineral oil(KZ),“KZ+malathion” and without insecticide), tricycle forward-speeds (0.6, 0.8, 1.0 and 1.2 m/s), the fog angles (30⁰, 45⁰ and 60⁰) and resonator length (74 and 174 cm). The maximum control efficiencies for the nymphs and adult insect were 84.7 and 95.81% respectively, using fog angle of 45⁰, resonator length of 174 cm, control material of “KZ” and forward-speed of 0.6 m/s. The fogger capacities were 93, 108, 120 and 132 tree/h using tricycle forward-speeds of 0.6, 0.8, 1.0 and 1.2 m/s respectively. Using optimum fog angle of 45⁰ with resonator length of 174 cm, the maximum yield of date-palm fruit is 109.6 kg/tree at forward-speed of 0.6 m/s and “KZ” controlling material. Meanwhile, the minimum yield recorded 88.2 kg/tree was obtained under forward-speed of 1.2 m/s and “Malathion” control material. Under fog angle  45⁰ approximately and resonator length of 174, the minimum range of hourly, operation and production costs of using the fogger attached to tricycle at forward speed range of 0.6-1.2 m/s were 24.6-26.2 L.E./h, 0.20-0.26 L.E./tree and 1.96-2.41 L.E./Mg fruit for “KZ”.
