Phytochemical Screening, Larvicidal and Pupicidal Activity of Murraya paniculata (L.) Jack (Rutaceae) Leaf Extracts against Three Important Vector Mosquitoes (Diptera: Culicidae)

Larvicidal and adult emergence inhibition activity of Abutilon indicum (Linn.) (Malvaceae) leaf extracts against vector mosquitoes (Diptera: Culicidae)

The crude leaf extracts of Abutilon indicum were evaluated for larvicidal, pupal deformities and adult emergence inhibition activity against vector mosquitoes viz., Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus. Larvicidal activity was carried out using WHO protocol. Hexane extract with LC50 value of 261.31 ppm after a period of 24 hr was found to be effective against Aedes aegy...

Larvicidal properties of Breyenia vitis-idaea (Burm.f.) Fischer (Euphorbiaceae) against important vector mosquitoes (Diptera: Culicidae).

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...

Larvicidal and phytochemical properties of Callistemon rigidus R. Br. (Myrtaceae) leaf solvent extracts against three vector mosquitoes.

BACKGROUND & OBJECTIVES Due to ever-growing insecticide resistance in mosquito vectors and environmental contamination by synthetic insecticides, plants may be a source of alternative agents for mosquito control. Therefore, the present investigation involved the determination of larvicidal and phytochemical properties of Callistemon rigidus leaf extracts against Anopheles gambiae, Aedes aegypti...

Larvicidal 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 ...
