Botanical insecticides are promising pest control agents. This research investigated the novel pesticidal efficacy of and extracts against four ectoparasites through treated envelopes. Seven days post-treatment (PT) with 25 mg/mL of and , complete mortality of the camel tick, and cattle tick, were reached. Against , the median lethal concentrations (LC) of the methanol extracts were 1.13 and 1.04 mg/mL and those of the hexane extracts were 1.47 and 1.38 mg/mL, respectively. The LC values of methanol and hexane extracts against were 1.09 and 1.41 plus 1.55 and 1.08 mg/mL, respectively. Seven days PT with 12.5 mg/mL, extracts completely controlled and ; LC of were 0.56 and 0.62 mg/mL for methanol extracts and 0.55 and 1.00 mg/mL for hexane extracts, respectively, whereas those of were 0.67 and 0.78 mg/mL for methanol extract and 0.68 and 0.32 mg/mL, respectively, for hexane extracts. extracts contained sesquiterpene, fatty acid esters and phenols, whereas those of possessed monoterpene, sesquiterpene, terpene alcohols, fatty acid, and phenols. Consequently, methanol extracts of and were recommended as ecofriendly pesticides.
植物源杀虫剂是很有前景的害虫防治剂。本研究通过处理信封调查了[两种植物名称]提取物对四种体外寄生虫的新型杀虫效果。用25毫克/毫升的[两种植物名称]提取物处理七天后，骆驼蜱[蜱虫名称1]和牛蜱[蜱虫名称2]全部死亡。对于[蜱虫名称3]，甲醇提取物的半数致死浓度（LC）分别为1.13和1.04毫克/毫升，己烷提取物的半数致死浓度分别为1.47和1.38毫克/毫升。甲醇和己烷提取物对[蜱虫名称4]的LC值分别为1.09和1.41以及1.55和1.08毫克/毫升。用12.5毫克/毫升的[两种植物名称]提取物处理七天后，完全控制了[蜱虫名称5]和[蜱虫名称6]；[蜱虫名称5]的甲醇提取物LC分别为0.56和0.62毫克/毫升，己烷提取物LC分别为0.55和1.00毫克/毫升，而[蜱虫名称6]的甲醇提取物LC分别为0.67和0.78毫克/毫升，己烷提取物LC分别为0.68和0.32毫克/毫升。[植物名称1]提取物含有倍半萜、脂肪酸酯和酚类，而[植物名称2]提取物含有单萜、倍半萜、萜醇、脂肪酸和酚类。因此，推荐[植物名称1]和[植物名称2]的甲醇提取物作为生态友好型杀虫剂。
