Larvicidal activity of medicinal plant extracts against Anopheles subpictus & Culex tritaeniorhynchus
BACKGROUND & OBJECTIVES Mosquitoes transmit serious human diseases, causing millions of deaths every year and the development of resistance to chemical insecticides resulting in rebounding vectorial capacity. Plants may be alternative sources of mosquito control agents. The present study assessed the role of larvicidal activities of hexane, chloroform, ethyl acetate, acetone, and methanol dried...
متن کاملVectorial role of Anopheles subpictus Grassi and Anopheles culicifacies Giles in Angul District, Orissa, India.
Malaria transmission by Anopheles subpictus Grassi, 1899 and Anopheles culicifacies Giles, 1901 was studied from March 2004 to February 2007 in Angul District, Orissa, India, which is highly endemic for malaria. Adult mosquitoes were collected from human dwellings using sucking tubes and a mechanical aspirator. After identification, some An. subpictus and An. culicifacies specimens were subject...

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 and Histopathological Effects of Cassia siamea Leaf Extract against Culex quinquefasciatus.
A traditional Thai medicinal extract from Cassia siamea was evaluated with respect to its larvicidal properties by determining the median lethal concentration (LC50) at 24, 48, 72 and 96 h against the fourth instar larvae of Culex quinquefasciatus, which is a carrier of mosquito-borne diseases, by studying the histopathological alterations. The 24, 48, 72 and 96 h LC50 values were 394.29, 350.2...
متن کاملBioefficacy of Cassia fistula Linn. (Leguminosae) leaf extract against chikungunya vector, Aedes aegypti (Diptera: Culicidae).
The leaf extract of Cassia fistula with different solvens viz, methanol, benzene and acetone were studied for the larvicidal, ovicidal and repellent activity against Aedes aegypti. The extract exhibited dose dependent activity and produced significant mortality. The 24 h LC50 concentration of the extract against Aedes aegypti were observed at 10.69, 18.27 and 23.95 mg/l respectively. Mean perce...
