Mosquitoes are the most common vector for transmitting causative agents from an infectious source to a susceptible host. The key tool for preventing the spread of infection is vector control. Mosquito control is achieved by a variety of means, including personal protection, the use of synthetic insecticides, and so on. Mosquito resistance to chemical insecticides has resulted in mosquito control failure all over the world. This study was done to evaluate the mosquito larvicide effect of to develop an effective herbal alternative for mosquito control.
Five different concentrations of in the range of 25-125 ppm were taken and subjected to bioassay against late third instar larvae of . After 24 h, mortality response was observed and compared with Neem seeds extract. Log probit regression analysis was applied to the mortality data to calculate the median lethal concentrations LC50 and LC90 for the larvae subjected to the treatment.
91 % mortality in larvae of Female was recorded at 125 ppm of . The mortality percentage increased with the increase in concentration. Hydro alcoholic extract of revealed LC50 value at 66.799 ppm and LC90 value at 119.709 ppm.
extract exhibited larvicidal activity against late third instar larvae of Female and was found to be more potent than Neem extract.
蚊子是将病原体从传染源传播到易感宿主的最常见媒介。预防感染传播的关键工具是病媒控制。蚊子控制可通过多种方式实现，包括个人防护、使用合成杀虫剂等。蚊子对化学杀虫剂产生抗性已导致全球范围内蚊子控制失败。本研究旨在评估[某种物质]的杀蚊幼虫效果，以开发一种有效的草药替代品用于蚊子控制。
选取25 - 125 ppm范围内的五种不同浓度的[某种物质]，对[某种蚊子]的晚期三龄幼虫进行生物测定。24小时后，观察死亡率反应并与印楝种子提取物进行比较。对死亡率数据应用对数概率回归分析，以计算接受处理的幼虫的半数致死浓度LC50和LC90。
在125 ppm的[某种物质]浓度下，记录到[某种蚊子]雌性幼虫的死亡率为91%。死亡率百分比随浓度增加而升高。[某种物质]的水醇提取物显示LC50值为66.799 ppm，LC90值为ll9.709 ppm。
[某种物质]提取物对[某种蚊子]雌性晚期三龄幼虫表现出杀幼虫活性，且发现其比印楝提取物更有效。
