The destructive aphid (Sitobion avenae) of wheat, generally accomplished by chemical pesticides, is responsible for the substantial agricultural damages that occur annually. The present experimental study, a protein elicitor, PeBL1, has been examined for the possibility of inducing a defense response to S. avenae in wheat. In comparison to the positive (Water) and negative 70.58 μg ml⁻¹ (50 mM Tris–HCl, pH 8.0) controls, the population growth (intrinsic Increase) rates of S. avenae (second and third generation) with PeBL1-treated wheat seedlings declined. S. avenae preferred control plants for colonizing in an experiment with the host selection compared with the PeBL1-treated wheat plants, with PeBL1 treated wheat seedlings; the nymphal development time of aphid has been extended. In comparison with positive (water) and negative controls, less fecundity was observed with less offspring's in PeBL1-treated wheat seedlings. S. avenae had a harmful surface environment for wheat seedlings treated with PeBL1, caused by trichomes and wax formation. The level of Jasmonic acid (JA), salicylic acid (SA) and ethylene (ET) was significantly higher, and the PeBL1 treated wheat seedlings had significant accumulations. The findings presented that PeBL1 considerably altered the wheat surface structure so that the replication of S. avenae was minimized and colonization was prevented. Defensive processes also include pathway activation (JA, SA, and ET). A biocontrol study for the use of PeBL1 in the protection against S. avenae has been produced in this area.

小麦的破坏性蚜虫（Sitobion avenae）通常由化学杀虫剂造成，每年都会造成大量农业损失。本实验研究，蛋白质激发子，PeBL1，已审查了诱导防御反应的可能性，麦长管蚜在小麦。与阳性（水）和阴性 70.58 μg ml ^-1（50 mM Tris-HCl，pH 8.0）对照相比，PeBL1 处理小麦的S. avenae（第二代和第三代）的种群增长（内在增加）率幼苗下降。燕麦与用 PeBL1 处理的小麦幼苗相比，与 PeBL1 处理的小麦植物相比，宿主选择实验中用于定植的优选对照植物；蚜虫的若虫发育时间延长。与阳性（水）和阴性对照相比，在 PeBL1 处理的小麦幼苗中观察到的繁殖力较低，后代较少。由于毛状体和蜡形成，S. avenae对用 PeBL1 处理的小麦幼苗具有有害的表面环境。茉莉酸（JA）、水杨酸（SA）和乙烯（ET）水平显着升高，PeBL1处理的小麦幼苗有显着积累。研究结果表明，PeBL1 显着改变了小麦表面结构，从而使S. avenae的复制被最小化并防止了殖民化。防御过程还包括通路激活（JA、SA 和 ET）。在打击保护利用PeBL1的生物防治研究麦长管蚜在这一领域已经产生。
