Insecticidal property of aloe, ginger, garlic, and hot pepper extracts were evaluated in the form of alone spray or in combination of two plant sources or as a mixture of all plant extracts in comparison to the insecticide Lambda on the mango scale insect, Aulacaspis tubercularis (Newstead) (Hemiptera: Diaspididae). Field experiments were carried out at Fayoum Governorate, Egypt, in February 2017 and March 2018. Results revealed that Lambda insecticide decreased the population of treated A. tubercularis, and the total reduction rates reached to 62.0 and 72.52% in seasons 2017 and 2018, respectively. Meanwhile, the used botanical mixture caused 83.60 and 72.52% reduction of the scale insects in the respective seasons. Also, results revealed that the combination of garlic and aloe was the most effective one in reducing A. tubercularis in the two successive seasons by 58.71 and 59.93%, respectively. The hot pepper was the least effective one in reducing population with the rates of 19.48% in season 2017 and 21.51% in season 2018.

植物提取物对芒果鳞茎虫（Aulasaspis tubercularis）（纽斯特德）的抑制作用（半翅目：蛇蝎科）

相对于芒果级昆虫结核分枝杆菌（Auracaspis tubercularis）的杀虫剂Lambda，以单独喷雾的形式或以两种植物来源的组合或以所有植物提取物的混合物的形式评估了芦荟，姜，大蒜和辣椒提取物的杀虫特性（纽斯特德）（半翅目：Dia科）。2017年2月和2018年3月在埃及法尤姆省进行了田间试验。结果表明，Lambda杀虫剂减少了治疗的结核分枝杆菌的种群，2017年和2018年的总减少率分别达到62.0％和72.52％。 。同时，所使用的植物混合物在各个季节减少了83.60％和72.52％的鳞屑昆虫。同样，结果显示，大蒜和芦荟的组合是减少A的最有效方法。连续两个季节结核菌分别增加58.71％和59.93％。辣椒是减少人口数量最无效的一种，2017年季节的比率为19.48％，2018年季节的比率为21.51％。
