Mosquitoes are blood sucking arthropods and serve as vectors of many diseases causing serious health problems to human beings. and were responsible for Filariasis and Dengue. Synthetic pesticides were effective against mosquitoes as well as main sources of environmental pollution and most of them are immunosuppressant. Botanicals were widely used as insecticides, growth disruptors, repellents, etc. The aim of this research was to determine larvicidal properties of powdered leaf, against late third or early fourth in-star larvae of and .
Larvae of and were tested at various concentrations of 100, 120, 140, 160, 180 and 200mg/100ml and mortality was recorded after 24h. The LC values of the leaf powder were calculated by Probit analysis.
The plant powder exhibited strong larvicidal activity against with LC value of 116.07mg/100ml against 124.25mg/100ml respectively. The result indicated that the plant powder of showed potential larvicidal activity against . and .
The overall findings of the present investigation suggested that the highly effective against and larvae. may be used as an alternative to synthetic chemical pesticides for control of vectors to reduce vector borne diseases and did not harm to total environment.
蚊子是吸血节肢动物,是许多疾病的传播媒介,给人类健康带来严重问题。[此处两个“and”可能有误,暂不影响整体理解]分别导致丝虫病和登革热。合成农药对蚊子有效,但也是环境污染的主要来源,且大多数具有免疫抑制作用。植物提取物被广泛用作杀虫剂、生长抑制剂、驱避剂等。本研究的目的是确定[植物名称]粉末状叶片对[蚊子名称1]和[蚊子名称2]晚期三龄或早期四龄幼虫的杀幼虫特性。
以100、120、140、160、180和200mg/100ml的不同浓度测试[蚊子名称1]和[蚊子名称2]的幼虫,24小时后记录死亡率。通过概率分析计算[植物名称]叶片粉末的LC值。
该植物粉末对[蚊子名称1]和[蚊子名称2]表现出较强的杀幼虫活性,对[蚊子名称1]的LC值为116.07mg/100ml,对[蚊子名称2]为124.25mg/100ml。结果表明,[植物名称]的植物粉末对[蚊子名称1]和[蚊子名称2]显示出潜在的杀幼虫活性。
本研究的总体结果表明,[植物名称]对[蚊子名称1]和[蚊子名称2]的幼虫高效。[植物名称]可作为合成化学农药的替代品用于控制病媒,以减少病媒传播疾病,且对整个环境无害。
