论文摘要
本研究研究了阿尔及利亚萨哈拉北部收获了两种植物的叶提取物的杀虫剂和除草剂作用。这些是阿拉伯氏菌（Cleome Arabica）（卡帕拉辛科）和pergularia tomentosa（Asclepiadaceae）。通过回流提取方法评估植物提取物的功效。与Tomentosa的提取物相比，对阿拉伯蛋白酶水的水提取物的植物化学筛查表明，活跃原理具有显着的丰富性。包括类黄酮，皂苷，糖苷，萜烯，固醇，脱氧糖，多酚和总生物碱。用阿拉比卡梭菌和tomentosa的水提取物处理的三分之一至100％的tribolium condo的成像，死亡率为73.33％至96.67％，36.67％至86.67％。估计阿拉比卡梭菌水提取物的致命时间50（TL50％）约为6.41天，而T。Concusum图像的提取物P. tomentosa则为6.94天。 tomentosa的提取物的毒性低于阿拉比卡菌的提取物。关于杂草dactyctenium eygyptium（poaceae）和包括hodeumvulgare和Triticumdurum（poaceae）在内的杂草种子的发芽测试的C. obalica和tomentosa的化推导性潜力，表明阿拉伯氏菌的抑制作用是非常重要的。它体现在H. ustgar和T. durum的空中和地下部分的生长中。对于用不同浓度处理的D.埃及种子的抑制率超过84.44％。抑制率在85.56％至91.11％的灌溉小麦灌溉时为80％至100％，但对用相同浓度治疗的大麦种子（80％至100％）的大麦种子只有55.56％至77.78％。
The present study investigates the insecticidal and herbicidal effects of leaf extracts from two plants were harvested in the Northern Algerian Sahara. These are Cleome arabica (Capparaceae) and Pergularia tomentosa (Asclepiadaceae). The efficacy of the extracts from the plants was evaluated by the reflux extraction method. The phytochemical screening of the aqueous extracts of C. arabica shows a remarkable richness in active principles in comparison with the extract of P. tomentosa; including flavonoids, saponosides, glycosides, terpenes, sterols, deoxyose, polyphenols and total alkaloids. The imago of Tribolium confusum treated with aqueous extracts of C. arabica and P. tomentosa at doses of 80% to 100% respectively have mortality rates of 73.33% to 96.67%, and 36.67% to 86.67%. The lethal time 50 (TL50%) of the aqueous extract of C. arabica was estimated about 6.41 days, and 6.94 days for the extract P. tomentosa for the imago of T. confusum. The extracts of P. tomentosa is less toxic than the extracts of C. arabica. The allelopathic potentials of C. arabica and P. tomentosa tested on germination of the seeds of a weed Dactyloctenium aegyptium (Poaceae) and two cultivated species, including Hordeumvulgare and Triticumdurum (Poaceae), show that the inhibitory effect of extracts of C. arabica is very highly significant. It manifests itself in the growth of the aerial and underground part of the H. vulgar and T. durum. The inhibition rate is more than 84.44% for D. aegyptium seeds treated with the different concentrations. The inhibition rates range from 75.56% to 91.11% for T. durum wheat irrigate at 80% to 100%, but are only 55.56% to 77.78% for barley seeds treated with the same concentrations (80% to 100%).
