In this research, the effect of five treatments of Arbuscular Mycorrhizal Fungi (AMF) including <em>Glomus caledonium, G. etanicatum, G. geosporum, G. intradicese</em> and <em>G.</em> <em>mosseae </em>together with control treatmenton total amount of phenol content in bell pepper and also their impact on biological parameters of <em>M.</em> <em>persicae</em> were investigated. Based on the results, the highest amount of the total phenolic compound in the plant infested with aphid was observed on<em> G. mosseae</em>and<em>G. intradicese </em>(686.1 and 664.3 mg/mL, respectively) and the lowest amount was on control (410.8 mg/mL).The shortest and longestadult longevity of the green peach aphid were observed on <em>G. mosseae</em>(16.00 days)and control (22.35 days), respectively. The net reproductive rate (<em>R</em>₀) varied from 37.54 to 53.34 offspring/individual, with the lowest and highest values obtained on <em>G. mosseae</em> and control, respectively.Also, the lowest intrinsic rate of increase (<em>r</em>) and finite rate of increase (<em>λ</em>) of the aphid were recorded on <em>G. mosseae</em> treatment (0.2867 and 1.3320 day^-1, resp.) compared to other treatments. The results of this study showed that <em>G. mosseae</em> treatment significantly reduced the population growth of <em>M. persicae</em>. Therefore, <em>G. mosseae</em> can be used to produce induced resistance in bell pepper to this aphid, which can be useful in the IPM program of this pest.
