Abstract

The effects of Neem Oil, Neem Leaf Extract and Beauveria bassiana on the larvicidal, pupicidal, adulticidal and anti-ovipositional activities of the filarial vector Culex quinquefasciatus were investigated. Neem Oil showed high bioactivity in all doses, while Neem Leaf Extract and B. bassiana were less active compared to Neem Oil. Neem Oil was found to be most effective and highly potent. The first instar larvae were found to be more susceptible
