Larvicidal efficacy of botanical extracts against two important vector mosquitoes.
OBJECTIVE To determine the larvicidal efficacy of different solvent leaf extract of Ervatamia coronaria and Caesalpinia pulcherrima against Anopheles subpictus and Culex tritaeniorhynchus. MATERIALS AND METHODS Twenty five early third instar larvae of Anopheles subpictus and Culex tritaeniorhynchus were exposed to various concentrations and were assayed in the laboratory. The larval mortality...
متن کاملLarvicidal Efficacy of Plant Extracts against the Malarial Vector Anopheles stephensi Liston (Diptera: Culicidae)
Malaria is transmitted by Anopheles stephensi and for controlling the malaria parasite Plasmodium spp., the vector mosquito has to be controlled. Extensive use of synthetic and chemical insecticides has resulted in environmental hazards and also in development of physiological resistance among vector mosquito species. Plant products are considered to be a potential alternative approach as they ...
متن کاملLarvicidal Efficacy of Strychnos nuxvomica Linn. (Loganiaceae) Leaf Extracts Against the Filarial Vector Culex quinquefasciatus Say (Diptera: Culicidae)
The larvicidal activity of hexane, chloroform and ethyl acetate leaf extracts of Strychnos nuxvomica against the third instar larvae of Culex quinquefasciatus was studied. The ethyl acetate leaf extract was found to be the effective larvicide with LC value of 222.28 and 146.99 ppm after 24 and 48 hours. The results indicate 50 promising larvicidal activity against Culex quinquefasciatus. Furthe...
متن کاملLarvicidal efficacy of Vernonia cinerea (L.) (Asteraceae) leaf extracts against the filarial vector Culex quinquefasciatus Say (Diptera: Culicidae)
The larvicidal efficacy of Vernonia cinerea leaf extracts against the common filarial vector, Culex quinquefasciatus was determined. Ground Vernonia cinerea leaves were sequentially extracted with ethyl acetate, chloroform, acetone and methanol. A series of concentrations of the extracts ranging from 0.05 – 2 mg/ml were tested against third instar larvae using WHO protocol and their percentage ...
متن کاملPreliminary evaluation of mosquito larvicidal efficacy of plant extracts.
Mosquitoes are the most important single group of insects in terms of public health importance, which transmit a number of diseases, such as malaria, filariasis, dengue, Japanese encephalitis, etc. causing millions of deaths every year. Repeated use of synthetic insecticides for mosquito control has disrupted natural biological control systems and led to resurgences in mosquito populations. It ...
