Oryzaephilus surinamensis (L.) and Sitophilus granarius (L.) are major pests of stored wheat, Triticum aestivum (Linn.) and cause huge economic loss to it. This study aimed to evaluate the toxic and repellent effects of Camelina sativa (L.) extract using green synthesis of silver nanoparticles against O. surinamensis and S. granarius. The bioassays were performed by applying three concentrations (5, 10 and 15%) of C. sativa extract and 200, 300 and 500 ppm in case of silver nanoparticles. Mortality was recorded at 24, 48 and 72 h while repellency was noted after 12, 24, and 36 h of the post-treatment. After 72 h of exposure, the highest concentration of C. sativa extract (15%) caused mortality of 43.1 and 35.2% to O. surinamensis and S. granarius, respectively. In repellency bioassays, the extract of C. sativa caused 37.7 and 30.2% repellency against O. surinamensis and S. granarius after exposure period of 36 h. While the highest mortality of 60.1% was observed against O. surinamensis at highest concentration (500 ppm) of the silver nanoparticles of C. sativa extract compared to S. granarius (46.2%) at same concentration after exposure period of 72 h. Highest repellency (42.7%) was observed against O. surinamensis at 500 ppm of the silver nanoparticles of C. sativa extract compared to S. granarius (36.2%) at same concentration after exposure to 36 h. The results revealed that green synthesized silver nanoparticles from C. sativa extract proved effective and can be used as eco-friendly management strategy of O. surinamensis and S. granarius.

surinamensis（L.）和Sitophilus granarius（L.）是储存的小麦Triesum aestivum（Linn。）的主要害虫，对其造成巨大的经济损失。本研究的目的是评估的毒性和驱避效果亚麻荠使用针对银纳米颗粒的绿色合成（L.）提取物O.盗和S. granarius。通过应用三种浓度（5、10和15％）的苜蓿提取物和200、300和500 ppm的银纳米颗粒进行生物测定。在治疗后12、24和36小时记录死亡率，而在24、48和72小时记录排斥反应。暴露72小时后，C的最高浓度。苜蓿提取物（15％）的43.1引起死亡率和35.2％至O.盗和小号。分别为格拉纳留斯。在排斥性生物测定中，C的提取物。暴露36小时后，苜蓿对苏里南O. surinamensis和S. granarius的驱避力分别为37.7％和30.2％。在暴露72 h后，在相同浓度下，苜蓿中华。提取物的最高浓度（500 ppm）对苏里南稻的最高死亡率为60.1％，而在相同浓度下，沙棘（46.2％）对苏里南稻（S. granarius）的最高死亡率为60.1％。观察到最高的排斥性（42.7％）Ø。与S. S.相比，C。sativa提取物的银纳米颗粒在500 ppm处具有苏里南藻。暴露36 h后，保持相同浓度的格拉纳瑞斯（36.2％）。结果显示来自绿色合成的银纳米颗粒C.苜蓿提取物证明是有效的，并可以用作环保型管理策略O.盗和S. granarius。
