Abstract

This study aims to study the population density of the Peach Aphid Myzus persicae Sulzer and  compared the efficiency of color traps with some insecticides Acetampride (ACelan 20% SL), Imidacloprid (Confidor 20% SL), Tiamethoxam (Actara 25 WG) and cold aqueous extract of Azadirachta indica seeds and Ricinus communis seeds in the insect control, The study was conducted in the Ishaqi city, Salahedin Governorate famous which known the cultivation of tomato Soalnum lycopersicum.The highest average of insects caught during  May 2020 was 85.42 adult/plant, while the lowest insects reached 12.50 adult/plant during March 2020 in the first site while the highest average of insects caught during May reached 86.21 adult/plant, while the lowest rate was 22.35 adult/plant during the March in the second site This study show that the yellow color more attractive colors than white and red and shows that the red color less attractive colors. The highest mortality rate of acetampride was 92.3% after 24 h of treatment ,while the highest mortality rate of thiamethoxam and amidacloprid was 85.65% and 55.52%, respectively, after 24 h of treatment.The results showed the effect of cold water extracts on mortality of M .persicae Sulzer  was 67.42% for the A.indica seeds, while the mortality rate was 78.59% for the R .communis, after 24 h, highest mortality rate of acetambride was 87.1% after 72 h of treatment, while highest mortality of thiamethoxam and amidacloprid was 71.3% and 49.2%, respectively, after 72 h of treatment. The results showed the effect of cold water extracts on mortality of M. persicae Sulzer, causes a mortality rate of 45.23% for the cold water extra of A .indica , while the mortality rate was 58.46% for the cold water extracts of castor plant R .communis after 72 h of treatment.
