Abstract

Background: Mosquitoes are blood sucking arthropods and serve as vectors of many diseases causing serious health problems to human beings. Culex quinquefasciatus and Aedes aegypti 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, Elytraria acaulis against late third or early fourth in-star larvae of Cx. quinquefasciatus and Ae. aegypti.

Methods: Larvae of Cx. quinquefasciatus and Ae. aegypti were tested at various concentrations of 100, 120, 140, 160, 180 and 200mg/100ml and mortality was recorded after 24h. The LC₅₀ values of the E. acaulis leaf powder were calculated by Probit analysis.

Results: The plant powder exhibited strong larvicidal activity against Cx. quinquefasciatus with LC₅₀ value of 116.07mg/100ml against Ae. aegypti 124.25mg/100ml respectively. The result indicated that the plant powder of E. acaulis showed potential larvicidal activity against Cx. quinquefasciatus and Ae. aegypti.

Conclusion: The overall findings of the present investigation suggested that the E. acaulis highly effective against Cx. quinquefasciatus and Ae. aegypti larvae. Elytraria acaulis 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.

白蛉对致倦库蚊和埃及伊蚊的杀幼虫活性(双翅目:库蚊科)

背景:蚊子是一种吸血节肢动物，是多种疾病的传播媒介，对人类健康造成严重威胁。致倦库蚊和埃及伊蚊是丝虫病和登革热的主要病原。合成农药除对蚊虫有效外，也是环境污染的主要来源，多数具有免疫抑制作用。植物药被广泛用作杀虫剂、生长干扰剂、驱蚊剂等。摘要本研究旨在测定黄菖蒲叶粉对大蠊3星末和4星初幼虫的杀虫性能。致倦库蚊和伊蚊。蚊。方法:采蚊幼虫。致倦库蚊和伊蚊。分别以100、120、140、160、180、200mg/100ml的不同浓度检测埃及伊蚊，并记录24h后的死亡率。采用Probit分析法计算了小檗叶粉的LC50值。结果:植物粉对Cx有较强的杀虫活性。致倦库蚊对伊蚊LC50值为116.07mg/100ml;埃及伊蚊分别为124.25mg/100ml。结果表明，黄芩植物粉具有潜在的杀虫活性。致倦库蚊和伊蚊。蚊。结论:本研究结果表明，黄芽孢杆菌对Cx有较好的防治作用。致倦库蚊和伊蚊。蚊幼虫。黄鞘翅可作为合成化学农药的替代品，用于控制病媒生物，减少病媒传播疾病，且对环境无害。
