Insecticides and repellent chemicals are used to control the exposure to disease vectors. In this study, the repellence activity of ethanol extracts of the leaves of spearmint (Mentha spicata) and rosemary (Rosemarinus officinalis) was evaluated against the adult stages of female Anopheles arabiensis. In addition, the larvacidal effect of seed powder of neem (Azadrichiata indica) was evaluated against the 4th instar larvae of Aedes aegypti under laboratory condition. M. spicata caused average percent repellence effects ranging from 95 to 97% at six different concentrations whilst, R. officinalis induced between 63 and 74%. One-way analysis of variance (ANOVA) revealed that there was no significant difference in the repellence effect among the different concentrations of M. spicata extracts used against An. arabiensis (F = 0.848; P = 0.542). In contrast, statistically significant variation in the repellence effects were observed among the different concentrations of ethanolic extracts of R. officinalis against An. arabiensis females (F = 3.609; P = 0.032). The mean percent larval mortality against Ae. aegypti caused by the seed powder of A. indica at a concentration of 5 g/250 mL was 58% at 24 h and 81% at 48 h. There was no significant difference in larval mortality between 24 and 48 h of exposure (t = 2.328; P = 0.145). In conclusion, ethanolic extracts of M. spicata and R. officinalis could be used as potential sources of repellents against An. arabiensis. Besides, A. indica seed powder could be a potential source of larvicides against the larvae of Ae. Aegypti.

杀虫剂和驱避剂用于控制疾病媒介的暴露。在这项研究中，评估了留兰香（Mentha spicata）和迷迭香（Rosemarinus officinalis）叶片的乙醇提取物对雌性阿拉伯按蚊成年期的驱避活性。此外，在实验室条件下，针对印度伊蚊的四龄幼虫评价了印em（Azadrichiata indica）种子粉的幼虫作用。在六种不同浓度下，M。spicata引起的平均排斥百分率在95％到97％之间，而R. officinalis诱发率介于63％和74％之间。单因素方差分析（ANOVA）显示，在不同浓度的十字花螺提取物对An。的驱虫作用之间，驱虫效果没有显着差异。阿拉伯（F = 0.848; P = 0.542）。与此相反，进行了不同浓度的乙醇提取物中观察到排斥作用统计学显著变化R.巴戟针对一种。阿拉伯女性（F = 3.609; P = 0.032）。相对于Ae的平均幼虫死亡率。埃及by草种子粉引起的埃及伊蚊浓度为5 g / 250 mL时24小时的58％和48小时的81％。暴露24至48小时之间的幼虫死亡率无显着差异（t = 2.328； P = 0.145）。总之，M。spicata和R. officinalis的乙醇提取物可以用作抗An。的驱避剂的潜在来源。阿拉伯菊。此外，A种子粉可能是杀灭Ae幼虫的潜在杀幼虫剂来源。埃及人。
