Abstract

Green peach aphid (Myzus persicae) is the most important pest of stone fruit trees such as peach and plum. It damages annual crops as common been, tomato, potato, cabbage and herbs. The aphid uses its slender stylet to penetrate the plant tissues intracellularly and consume considerable amount of phloem sap, causing extensive damage to host plants. In this study, ability of β-aminobutyric (BABA) and salicylic acid (SA) to induce resistance against Myzus Persicae on broad bean (Vicia faba) were investigated. For this purpose, one phenotype experiment and one molecular experiment were performed. Greenhouse experiments showed that BABA and SA treatments had inhibitory effects on aphid`s growth and development by increasing life cycle length and decreasing of reproduction. Results of molecular experiment showed increasing  mRNA levels of chitinase, after application of BABA and SA.
