The mosquitocidal activity of methanolic extracts of Lantana cramera root and Anacardium occidentale leaf: role of glutathione S-transferase in insecticide resistance.

Larvicidal activity of methanolic plant extracts of Lantana cramera (P1) root and Anacardium occidentale (P2) leaf was investigated against the larvae of the three mosquito species (Culex quinquefasciatus, Anopheles stephensi, and Aedes aegypti reared in the laboratory), and the respective glutathione S-transferase (GST) activity was analyzed as an index of protection against the extracts. The LC50 (extract concentration that shows 50% mortality) values of P1 extract for An. stephensi, Ae.
