Nano-Imidaclorprid was tested against following olive insect pests: Bactrocera oleae, Ceratitis capitata and Prays oleae under laboratory and field conditions. Results obtained showed that the LC50 of Imidaclorprid obtained 200, 221 and 225 mg/L for B. oleae, C. capitata and B. oleae, respectively. The LC50 of the corresponding pests after nano- IMI treatments obtained, 99, 111 and 115 mg/L, respectively. Under field conditions the infestations of the three olive pests were recorded, the lowest percent of infestations. The percentage of B. oleae was significantly decreased to 12±4.2 and 12±3.5 individuals as compared to 79±1.2 and 81±1.2 individuals in the control. During season 2013 the weight of the olive fruit obtained significantly increased to 5896± 20.10 kg/feddan as compared to 3120± 20.72 kg/feddan in the control. During season 2014 the weight of the olives fruits were significantly increased to 6994±31.18 kg/ feddan as compared to 2909±81.50 kg/feddan in the control. Percentage of the olive insect pests under field conditions which show that the imidaclorprid causing a significant decrease in the insect pests infestations.
