Bioactive potentials of Melia azedarach L. with special reference to insecticidal, larvicidal and insect repellent activities

S Sabiha, Hasan Ali, Kamrul Hasan, ASMS Rahman and Nurul Islam

A lab experiment was conducted during June 2015 - Feb 2016 at the Crop protection & Toxicology Lab., University of Rajshahi, Bangladesh to evaluate the insecticidal, repellent and larvicidal efficacy of Petroleum ether (Pet. ether), CHCl3 and CH3OH extracts of the fruits and leaves of Melia azedarach against adults of Tribolium castaneum and larvae of. Tribolium adults exhibited mortality when exposed to all the doses of Pet. ether extracts of fruits and leaves whereas the CHCl3 and CH3OH extracts of the same didn’t show mortality at all. All extracts showed larvicidal activity by yielding different LC50 values in different time exposure. The Pet. ether extracts of fruit did not show repellent activity, while the Pet. ether extract of leaf showed repellent activity at 5% level of significance (P<0.05) and the CHCl3 and CH3OH extracts of both fruit and leaf offered repellent activity at 5% level of significance (P<0.05).
