Field evaluation of malathion fogging against Japanese encephalitis vector, Culex tritaeniorhynchus.
Malathion technical fogging is considered as a potent tool for the control of vectors of various diseases. The purpose of fogging is to interrupt the further transmission by killing the vectors carrying pathogens. Fogging operation was launched in India in 1970 as an urgent remedial measure. Thermal fogging with malathion is very effective in malaria and dengue outbreaks, but it has a very litt...

متن کاملInsecticide susceptibility status of Culex tritaeniorhynchus giles, vector of Japanese encephalitis in Delhi.
Laboratory studies were carried out to ascertain the current susceptibility status of adult and larval stages of the Culex tritaeniorhynchus mosquito, vector of Japanese encephalitis, to various insecticides used under public health programs in India. The present study revealed that exposure of adult mosquitoes to diagnostic concentrations of DDT - 4.0%, malathion - 5.0%, fenitrothion - 1.0%, a...
متن کاملLarvicidal 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...
متن کاملLarvicidal 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...
